Final report April 2010
INTRODUCTION Nicaragua is a Central American country with a population of just under 6 million. It is one of the least developed of the region with almost half of the population living in poverty and 17% in extreme poverty, higher in rural than urban areas. The population is of mixed ethnic origin and is also a young population with more than half under 17 years of age. Nicaragua has several public health and nutrition problems but progress has been made in recent years. Infant mortality rates decreased from 58 per 1,000 births in 1992-93 to 39 in 2001, but since then have only reduced slightly to 29 in 2006 (ENDESA 2006/7). Child malnutrition rates at the national level have also decreased: stunting or chronic malnutrition in children under 5y has diminished from 25% in 1998 to 20% in 2001 and in 2006/7 was 17.5% (NCHS reference standard), although wide disparities between urban (12.3%) and rural (22.6%) areas exist. Nicaragua has a significant public health problem of Vitamin A deficiency in both children and pregnant women and anaemia is prevalent, particularly in these same vulnerable groups. However there have been several national interventions to address these problems. These include fortification of sugar with Vitamin A since 2000, Vitamin A supplementation for children under 5y and postpartum women and fortification of wheat flour with iron, thiamin, riboflavin, niacin and folate since 1997 (Mora 2007). Infant feeding practices as described in ENDESA 2006/7 are not optimum. Although most mothers in this national survey (94.5%) started breastfeeding, the giving of prelacteal feeds was not uncommon and exclusive breastfeeding amongst infants 0 – 3 months of age is quite low, 37.9%, having decreased since 2001 (39.3%) but higher than in 1998 (29.5%). The current rate is lower than some other countries in Latin America (Update USAID). Inadequate introduction of complementary foods was also described. In many rural areas there is difficulty of access to health and nutrition services. In recent years the MOH has established several programmes to address this such as the AIN-C (Integrated child attention in the community) and PROCASAN (Community programme of health and nutrition) in which education and communication strategies are an integral component (Mardini). In this context CARE Centro America in Nicaragua is implementing a project with the objective of improving infant and maternal feeding practices for better nutrition and the
growth and health of young children and their mothers in specific districts. A baseline survey for this Project “Ventana de Oportunidad” has been conducted, with data collected on infant and young child (IYC) nutritional status (anthropometry) and feeding practices in a cross-sectional sample of 1152 children and their mothers from four districts, each with intervention and control participant communities. The instrument that was applied was developed locally, but is similar to that currently being tested by WHO and other organizations to measure infant feeding practices for the recently defined and published updated infant feeding indicators (WHO Indicators for assessing infant and young child feeding practices). We have analyzed this baseline data and present the results according to the IYCF and other indicators of the project for the intervention and control populations. METHODOLOGY Data management and analysis The data was received from CARE as an Access file. It was first reviewed to detect abnormal values, outliers, inconsistencies and doubts regarding each of the variables in the 7 sections of the survey instrument, both at the individual level and in relation to the other variables. The number of registries and variables were checked within each section and any duplicate values identified. The ranges and logical values for each variable were checked. All queries were consulted with Lic. Carlos Rojas with whom criteria for validity, inclusion/exclusion and any modifications were discussed and corrections made where necessary. SPSS version 17 was used for the data checking and analysis. Exclusions from the analysis included 15 children for the anthropometry analyses as they were outliers as defined by the NCHS or WHO 2006 growth standard references as described below in section 3. Ten cases were identified that reported the infant received no liquid during the first 3 days after birth; this was confirmed against the survey forms and it was decided to do the analysis with and without these 10 cases; in fact there were no differences in the results with their exclusion. According to the characteristics of each variable the corresponding statistical test was applied. In the case of categorical variables, for the comparison of proportions between intervention and control, Pearson's Chi square test was applied where the expected frequencies were greater than 5; when it was found that at least one of the expected frequencies was less than 5 we proceeded to make the correction of continuity or Yates’ correction, typically used in CHI-square analysis with 1 degree of freedom where expected frequencies of less than 5 are found. For the comparison between intervention and control for the continuous variables a variance analysis was conducted. In all cases if the p-value was < 0.05 it was considered statistically significant. In the analysis we assumed that there was only one child younger than 24 months per household, as duplicates were not found in the identification code RESULTS The results are presented according to the terms of reference and the IIN analysis proposal, with the incorporation of the additional indicators and components requested by CARE in March 2010.
Description of the population Four districts were included in the baseline survey, with intervention and control communities in each. The total number of children included in the survey was 1152 of which 722 were from the intervention communities and 430 from control. The distribution of the sample from the different districts is shown in the following table.

In 2 cases in the intervention group the father was the informant and in 5 cases for both intervention and control it was the grandmother. The mean age of the mother was 25.3 years, similar between intervention and control groups, ranging between 14 and 58 years for the intervention group and between 14 and 44 years for the control group (see Table 1A in Appendix). The median age was 25 years and 24 years respectively for control and intervention groups. Table 2 shows the education level of the informant. A high proportion of those interviewed were illiterate (30.9%) or with some, incomplete primary schooling (47.2%). The education levels of the informant are the same between intervention and control groups.

The age of the child at the time of the survey was calculated from the birth date. This was obtained mostly from the growth monitoring carnet (86.0% control, 91.1% intervention) or the birth certificate (1.6% control, 1.0% intervention) or other non-specified document (11.9% control, 7.9% intervention). For only 2 children in the control group was there no birth date. 50.7% of the children were female, 49.3 % male, similar between control and intervention groups.
Section 03 of the survey instrument: Anthropometry. Children were measured for length and weight. All length measurements were done in a supine position as the children were under 2 years. Nutritional status of the children has been calculated using both the NCHS growth reference standards and the more recent, internationally adopted WHO 2006 (WHO) standards (WHO Anthro 3.01 April 2009) A total of 1137 children were included in the nutritional status analysis. Fifteen children were excluded as they were outside the accepted range for either the NCHS or WHO reference standards, shown in the appendix Table 2A. Twelve children were outside the NCHS range for one of the indicators and 7 for one of the WHO indicators (4 of these were the same as for NCHS plus 3 additional children). All 15 were excluded so that the evaluation of nutritional status by the two reference standards was of the same population. Nutritional status Z-scores using WHO 2006 and NCHS reference standards Under nutrition The description of the anthropometric Z-scores is presented by age group for intervention and control populations in the Appendix (Tables 3A – 8A). Using the WHO 2006 reference the mean length for age Z-score is -0.38 for infants 0 – 5.9 months and decreases with age, reaching a mean of -1.45 for the 12 – 23 age group (Table 3A), a typical growth faltering pattern of developing countries. The HAZ-scores are similar between control and intervention groups. Similarly, weight for age decreases with increasing age although less than for length. The mean Z-score is -0.21 (+1.06) for infants 0 – 5 months, and reaches -0.56 (+1.10) for the 12 – 23 month age group (Table 4A). The control group has a significantly lower Z-score than the intervention population for the youngest age group (p=0.047) but for the other ages the Z-scores are similar between groups. The WHZ-score is around 0 for each age group, indicating that this is not a population with wasting (Table 5A). However there are small but significant differences between intervention and control for the youngest 2 age groups, showing a lower mean WHZ for the control group. Using the NCHS reference standards the tendencies for the Z-scores are similar to those using the WHO standards although there are some differences in the values, shown in Tables 6A – 8A. The mean HAZ ranges from -0.25 (+0.89) for infants 0 – 5 months to -1.39 (+1.16) for the 12 – 23 month age group (Table 6A), values higher than when using WHO 2006 but with no significant differences between intervention and control populations. Mean WAZ ranges from 0.22 (+0.99) for infants 0 – 5 months to -0.97 (+1.07) for the oldest age group, but in this case giving lower values than for WHO (Table 7A). Similarly the mean WHZ is lower using the NCHS reference than for WHO, but showing the same significant differences between intervention and control groups for the 2 youngest age groups (Table 8A). Tables 3-5 show the proportion of IYC with under nutrition according to the WHO reference standards. The proportion of children with stunting starts at 4.8% for the younger age group and increases with age, reaching a high prevalence of 30% in the 12 – 23 month age group (Table 3). There are no differences between control and intervention groups.

Similarly, the proportion of children with low weight for age starts at 4.5% and also increases with age but less than for stunting, reaching around 9% for the 12 – 23 month age group (Table 4). There are no differences between intervention and control populations.

Table 5 shows that the mean wasting (low weight for height) is 4.5 – 2.2% of children according to age group. However, there is a significant difference between control and intervention groups for the 6 – 11 month age group, however this represents very few children.

Tables 6 – 8 show the proportion of IYC with malnutrition according to NCHS reference standards. The pattern of increasing stunting prevalence with increasing age is similar to that for the WHO standards but showing a lower proportion of children stunted than with the WHO standard across age groups. The results are similar between control and intervention groups.

Low WAZ increases with age from 1.1% in the youngest age group reaching 15% for the 12 – 23 months age group using the NCHS standards (Table 7). This is higher than with the WHO standards.

Total 2.6 2.0 2.2 0.495 ª = with Yates’ correction In summary, the above tables show that the there are differences in Z-scores of the IYC in this population when using the WHO 2006 or the NCHS reference standards, to be expected from comparisons made in other countries. For length for age, the mean Z-scores are slightly higher when using the NCHS standards than for the WHO standards for the youngest age group, 0 – 5.9 months, similar for the middle age group and again higher with NCHS for the 12 – 23.9 month age group. In the case of weight for age the mean Z-score values for this population are higher using the WHO standards except for the youngest age group, and in the case of weight for length, higher Z-scores are found with the NCHS for the youngest age group, similar values between the 2 standards for the 6 – 12 months but higher with the WHO standards for the children 12 – 23.9 months. When comparing the proportion of the population with under nutrition between the 2 reference standards, as defined by <-2sd, there is a higher proportion of stunted children with the WHO 2006 standards than with the NCHS in all age groups, also as expected. In the case of weight for age there is a higher proportion of children below -2sd in the youngest age group when using the WHO standards, a similar proportion for the middle age group but a higher proportion for the 12 – 23.9 month age group with the NCHS standards. In general the nutritional status for under nutrition is similar between the control and intervention groups. There are however significant differences between these 2 groups for Z-scores for weight for length (WHZ) for children 0 – 11.9 months using both NCHS and WHO standards although the proportion of children with low WHZ is similar, with the exception of 6 – 11.9 months using the WHO standards. Differences are also found using the WHO standards for weight for age Z score for the 0 – 5.9 months age group. There is a difference in the proportion of children 6 – 11.9 months with <-2sd weight for length for the WHO standards between study groups. Overweight and obesity As well as under nutrition there is growing concern about overweight in IYC and the risks this can bring in later life. The following categories of Z-scores for weight for height (length) are used to assess overweight and obesity for both WHO 2006 and NCHS reference standards: Z-score WHZ: 1 – 2 = possible rick for overweight
2.01 – 3 = overweight >3 = obese
In addition WHO 2006 assesses this condition using BMI for age, using the same categories. Table 9 shows the WHZ for overweight and obesity for all IYC 0 – 23 months of age by study group using the WHO reference standards. The prevalence is low prevalence: a total of 3.8% of the children classified as overweight and under 1% obese in this age range. However there are 19% of children classified as possible risk for overweight as defined by WHO. The distribution is similar between intervention and control communities.

>3, obese 0.2 1.3 0.9 *Chi-square = 0.164 The prevalences for overweight and obesity by age and study group is shown in Table 9A in the appendix. There is a tendency for overweight and obesity to decrease with increasing age, from 6.7% in the youngest age group to 3.6% in the oldest, although the risk for overweight is less in the youngest group than the 2 older groups. The prevalences are similar between intervention and control groups although there is a small but significant difference for infants 6 – 12 months. The WHO 2006 reference standards allow the calculation of BMI for age for these young children. The prevalences of possibly at risk of overweight, overweight and obese using this indicator for children 0 – 23 months, shown in Table 10, are very similar to the results presented above, with a prevalence of overweight and obesity of 5.7%, and no differences between study groups. However there are some differences in the patterns by age group with a higher prevalence of possible at risk for overweight in the older age group (24.6%) (Table 10A). There is a tendency for a higher prevalence in the intervention group but this only reaches significance in the infants 0 - 6 months.

Using the NCHS reference standard 4.4% of children under 2 years are classified as overweight or obese, values similar to the WHO reference (Table 11). However 13.6% of children is classified as at possible risk for overweight, a lower proportion than with the WHO reference. Table 11A in the appendix shows the rates of overweight by age and study groups. There is a higher prevalence of overweight and obesity in the children in the youngest age group (7%), decreasing with age to 2.2% at 12 – 24 months, but the proportion is small. The higher rates in the youngest children probably reflect the growth pattern of breastfed children when using NCHS. There are no differences between intervention and control groups.

Also there is a similar pattern between intervention and control groups. Overweight and breastfeeding pattern. This data was used to explore a relationship between overweight and breastfeeding practices in this population. Using the WHO 2006 standards we present results of overweight with exclusive breastfeeding in infants under 6 months (Table 12) and for continued breastfeeding for children 12-15 months (Table 13). There is an apparent tendency for higher rates of possible risk for overweight amongst infants not exclusively breastfed, but there is no difference in prevalences of overweight or obesity. This is also a small sample and no definitive association is indicated. When using BMI the results are similar between the 2 groups as shown in Table 12A in the appendix.

10.8 19.8
2.01– 3 overweight 6.1 5.0 >3, obese 0.7 1.7
For continued breastfeeding at 12 – 15 months there appears to be a tendency for a greater proportion of children to be at possible risk of overweight amongst those not breastfeeding (Table 13). A similar tendency, although with higher prevalences, is found with BMI for age (Table 13A). However, with the small sample size, especially of the children not receiving breastmilk at this age, as well as the extremely low prevalences of overweight and obesity at this age, no association can be concluded.

Infant and young child feeding core indicators are presented using the definitions in: Indicators for assessing infant and young child feeding practices. Part I. Definitions. WHO 2008. The complete sample of 1152 children was used for these analyses. a. Table 14 shows early feeding practices during the first 3 days after the birth of the infant. Almost all mothers gave breastmilk but 24% gave another liquid or drink during that time. This was most frequently sugared water, milk or tea or coffee. Honey was given to 5% of infants. The early breastfeeding (BF) initiation indicator, putting the infant to the breast within 1 hour of birth, was calculated using the following formula.

Early breastfeeding was further explored by place of birth: institutional or home. Table 15 shows the percent of infants put to the breast during the first hour after birth for institutional or home births. It can be seen that the majority of infants, were put to the breast within the first hour, although this was significantly higher for institutional births, and similar between intervention and control communities.

b. Exclusive breastfeeding for infants under 6 months Table 16 shows the infant feeding practices during the first 6 months of age. Most mothers breastfed (94%) but other liquids, particularly water, cow’s milk and “fresco” were also given. Patterns were similar between control and intervention groups although there was a higher use of fresco in the intervention group.

Total number of infants 0 – 5 months of age Figure 1 and table 14A show the prevalence of EBF for different age groups. 56.5% of infants 0-5.9 months were reported to be exclusively breastfed; 60.2% in the control group and 54.1% in intervention. 80.7% of infants were EBF in the first month and this decreased to 26% at 4 – 5 months. Breastfeeding patterns were similar between control and intervention groups, except for the older age group where there was a considerably higher rate of EBF in the control group. The “n” in table 14A is the sample for each of these age groups; care needs to be taken in the use of the indicators for those age groups where the sample is small, specifically for the for the 2 monthly age group intervals.

c. Continued breastfeeding at 1 year and at 20 – 23 months Breastfeeding at 1 year and at 20 – 23 months were calculated using the following formulae respectively. Children 12 – 15 months who received breast milk during the previous 24 hours x 100
Children 12– 15 months of age
Children 20 – 23 months who received breast milk during the previous 24 hours x 100 Children 20 – 23 months of age
The validity of these indicators depends upon sufficient sample size in these age groups; there appears to be ample sample in both of these age groups in this baseline survey. Figures 2 and 3 and table 15A show that 85% of children were still breastfed at 12 – 15 months, and 53% at 20 – 23 months, indicating a high proportion of children were breastfed at 1 year and more than half of children were breastfed at the end of the second year. A lower proportion of children were breastfed at 20 – 23 months in the intervention group than control.

d. Introduction of complementary foods. The indicator for the introduction of appropriate complementary foods (solid, semi-solid or soft foods) for children 6 – 8 months was calculated using the following formula. Infants 6 – 8 months who received solid, semi-solid or soft foods in the previous 24 hours x 100
Infants 6 – 8 months Eighty-six percent of infants were reported receiving solid, semi-solid or soft foods at 6 – 8 months of age (Table 17), similar between intervention and control groups. Care needs to be taken to be sure that there is sufficient sample in this narrow age range; however with a total of 199 this should be sufficient for use of this indicator.

e. The process of infant feeding practices, breastfeeding and introduction of other liquids and complementary foods by month of age is illustrated in Figures 4 and 5. Figure 4 shows how the proportion of exclusively breastfed infants decreases with age and the increase in consumption of solid, semi-solid or soft foods during the first year. By 6 – 7 months there is almost no EBF as most infants are receiving semi-solid complementary foods.

f. Breastfed infants (6 – 9 months, a 4-month period) with timely introduction of complementary foods An additional, previous indicator is presented in Table 18 showing the introduction of solid, semi-solid or soft foods over a wider period, 6 – 9 months. This earlier indicator includes receiving breastmilk and is calculated using the following formula. Thus, as this is not comparable with the current 6 – 8 month indicator, we present for all children and for those receiving breastmilk in Table 18.

g. Minimum dietary diversity Figure 6 and table 16A show the different food groups of the survey instrument consumed by children 6 – 23 months. Food groups consumed (yesterday) by most children were cereals and beans, followed by milk products, fats, and non vitamin A rich fruits and vegetables. Patterns were similar between control and intervention groups except for roots and tubers, vitamin A rich fruits, fats and chocolates/sweets. 32.8% of children (0 – 23 months) were given a feeding bottle, similar between intervention and control groups.

The 14 food groups of the survey were grouped into 7 food groups as defined in the WHO indicators to calculate dietary diversity; table 17A shows the 7 food groups and the corresponding assignation of the survey food groups to each of these. The minimum dietary diversity indicator is the consumption by the infant of 4 or more of the 7 food groups on the previous day and is calculated using the following formula for children 6 – 23 months of age: Children 6 – 23 months who received foods from >4 food groups during the previous day _______________________________________________________________________
Children 6– 23 months of age
As can be seen in the figure 7 and table 18A, half of all children 6 – 23 months met the minimum dietary diversity, with a similar proportion in both study groups.

The minimum dietary diversity data for breastfed and non breastfed children by age group are presented in Figure 8 and tables 19A and 20A in the appendix. For breastfed children 47.2% met this criteria and for non breastfed, 60%, possibly due to more non breastfed children receiving cow’s milk (data not analysed) and so these values between breastfed and not breastfed children should not be directly compared. In the case of breastfed children the proportion of children with minimum dietary diversity increases with age, whereas this does not occur with the non breastfed children, however, as mentioned above, these cannot be directly compared, and in the latter case the small sample in each of the sub age groups should be taken into consideration.

h. Minimum meal frequency The minimum meal frequency, number of meals or feeding episodes consumed by the child during the previous day or night, is a proxy for adequate energy intake from complementary foods of the child based on the following minimum times according to age and breastfeeding status. In the case of breastfed children it includes non-liquid foods and for non-breastfed children also includes milk feeds. The minimum feeding frequency definitions are:
- 2 times for breastfed infants 6 – 8 months - 3 times for breastfed infants 9 – 23 months - 4 times for non breastfed infants 6 – 23 months
“Meals” include meals and snacks other than trivial amounts, which we assume is implied in question 18 of the survey instrument. This indicator is calculated from the following 2 fractions:
Breastfed children 6 – 23 months of age who received solid, semi-solid or soft foods the minimum number of times or more during the previous day
Breastfed children 6 – 23 months and
Non-breastfed children 6 – 23 months of age who received solid, semi-solid or soft foods or milk feeds the minimum number of times or more during the previous day
Non-breastfed children 6 – 23 months
As shown in Figure 9 and Table 21A, 71.9% of children 6 – 23 months met the minimum meal frequency, similar between intervention and control groups. This indicates however, that 28.1% of children are not meeting even minimum meal frequency.

For breastfed children 68.8% meet the minimum meal frequency (Figure 10). There is a higher proportion of non breastfed children meeting the minimum food frequency (84.0%), probably due to the number of milk feeds that this group receives.

The proportion of children meeting minimum meal frequency is presented by sub age groups and shown in Tables 22A and 23A in the Appendix. For breastfed children there is
an increase with age group, and similar between intervention and control; for the non breast fed children this increase is not observed. Table 19 shows the mean number of feeding frequency of solid, semi-solid and soft foods during the previous day and night for breastfed children and the number of feeding frequency of solid, semi-solid and soft foods for non breastfed children. In the case of breastfed children this ranges from 2.2 to 3 times according to age and for non breastfed from 2.3 to 3.2 with increasing age and similar between intervention and control communities.

i. Minimum acceptable diet The minimum acceptable diet is a composite indicator which includes both minimum feeding frequency and minimum dietary diversity, thus giving an approximation of energy intake and dietary quality. The WHO indicator is calculated from the following 2 fractions:
Breastfed children 6 – 23 months of age who had at least the minimum diversity and the minimum meal frequency during the previous day
Breastfed children 6 – 23 months and
Non-breastfed children 6 – 23 months of age who received at least 2 milk feedings and had at least the minimum diversity not including milk feeds and the minimum meal frequency during the
previous day Non-breastfed children 6 – 23 months
As number of milk feeds is included in the minimum meal frequency for non breast fed children, milk is excluded from the 4 groups for diversity score in this indicator so as not to overestimate with the presence of milk. Figure 11 and Table 24A show that only 34.9% of all children 6 – 23 months of age meet the criteria for a minimum acceptable diet in this population, similar in intervention and control groups. Only 38.1% of breastfed children and 22.3% of non breastfed children met this criterion as shown in Figure 12. It is lower in non breastfed children probably because milk and milk products group is excluded from contributing to the diversity score in this case as it is included as number of milk feeds. The proportion of children increases with age for breastfed children (Table 25A), with a significantly higher proportion in the intervention group for the 12 – 17 month group, but this tendency is not seen with the non breastfed children (Table 26A).

j. Consumption of iron-rich or iron-fortified foods This indicator is a composite indicator that reflects the presence of iron containing foods in the child’s diet. It includes both iron-rich foods (new food group assignation 1) and/or the presence of an iron fortified food or foods fortified in the home (e.g. sprinkles). It is calculated using the following formula:
Children 6 – 23 months of age who received an iron-rich food or a food that was specially designed for infants and young children and was fortified with iron, or
a food that was fortified in the home with a product that included iron during the previous day Children 6 – 23 months
Only 35.4% of children 6 – 23 months consumed an iron rich of iron fortified the previous day increasing slightly with age and similar between control and intervention groups as shown in Figures 13 and 14 and Table 27A.

This indicator is disaggregated for the proportion of children who consumed iron rich (food group assignation 1) or iron fortified foods by age group (Figure 14 and Table 28A). The mean proportion of children receiving food from the meat group ranged from 12 – 27% according to age, with significant differences between control and intervention group for age groups 6 – 11 and 18 – 23 months. The mean proportion of children who received fortified foods ranged from 18 – 30% with a significant difference between control and intervention groups for the oldest age group.

k. Bottle feeding: The indicator of proportion of children 0 – 23 months who are fed with a bottle was calculated using the following formula:
Children 0 – 23 months who were fed with a bottle during the previous day Children 0– 23 months of age
Around one third of the population (32.8%) was fed using a feeding bottle in this population, similar between control and intervention groups as shown in Table 20. 21.6% of infants 0 – 6 months were given a bottle and this increased to around 36% 6 - 23 months.

Section 05 of survey instrument: Maternal and child care. Table 22 gives the results for prenatal attention that the mothers received. Eighty-eight percent of mothers had at least one prenatal check up, mostly done by a doctor and/or nurse. These mothers had a mean of 4.4 check ups during their pregnancy with a range of 1 – 9. The results are similar between control and intervention groups with the exception of who did the prenatal check ups. Distance was a predominant reason for not having a check up amongst those few who did not.

This was more frequently from “brigadistas”, followed by relatives, with differences in these between control and intervention groups.
A high proportion of mothers reported receiving (82%) and of these, taking (99%) iron supplements during pregnancy, similar between control and intervention groups.

About half (52%) of mothers had an institutional birth and 48% a home birth (Table 24). Forty-seven percent of mothers reported that a doctor attended at the birth of their infant, followed by a midwife (28%, nurse (23%) and husband or relative (19%). This was similar between control and intervention groups except in the case of the nurse. The most common reason for not being attended by a doctor or nurse was that the baby came prematurely, followed by distance (12%) or that they did not consider it necessary (9.6%). For this latter reason there was a difference between control and intervention groups. Seventy- eight percent of mothers reported receiving support for their breastfeeding or infant feeding, mostly from their own mother, followed by relatives, husband and then
mother in law. The most common type of support received was help with the housework (612%). Table 24. Maternal and child health care: Attention during birth and breastfeeding Control

Child health care is presented in Table 25. The majority of infants were vaccinated in the first 6 weeks (84%) and in the last 6 months (79%); in this latter variable there is a difference between control and intervention groups. A high proportion of children had diarrhoea in the past 2 weeks (40%). Food was continued to be given to the child during the episode of diarrhoea in 2/3 of the population, either the same as normal (33%) or less than normal (34%); but 32% did not give food during the episode. Approximately similar proportions reported giving or not giving liquids during the diarrhoea. Fifty-three percent of children were reported to have cough in the past 2 weeks and a high proportion of these with rapid or difficulty with breathing. The proportion of children who continued to be fed the same as normal was 35%, or less than normal, 31%, during the cough episode, and 31% were reported to not be fed with cough. Seventy-three percent of children were reported to have growth monitoring check ups, being lower in control than in the intervention group. The mean number of checkups reported was 3.8, with a range of 0 – 15 check ups. This will obviously be related to the age of the child at the time of the survey.

Section 06 of the survey instrument: Knowledge and information The most common source of information regarding child feeding was health personnel (Table 26); Brigadistas/ midwives, health personnel were most frequently mentioned by the mothers as having talked to them about child feeding (around 32% in each case).The mother’s own mother was the next most frequently mentioned (20%). There was a significant difference in the frequency with which the mother’s mother and the husband were mentioned between control and intervention groups. How to feed the child was the topic talked about most mentioned by the mothers (40%) followed by types of food to give the child and the recommendation to exclusively breastfeed for the first 6 months. There was a significant difference between control and intervention groups regarding the topics related to giving BM immediately after birth and feeding the child during illness, in both cases more frequently mentioned in the intervention group. Mothers reported that the source they most trusted for feeding advice was health personnel (42%) followed by brigadistas /midwives and then the mother’s own
mother. There was a difference in the latter between control and intervention groups. The results were very similar for whose recommendation the mother follows. Mothers reported the most frequent source for hearing or seeing information about feeding or caring for their child was the radio (66%) followed by the health centre. Differences are observed for the health centre and the church between control and intervention group.

a=Yates’correction Section 07 of the Surrey instrument: Maternal nutrition Dietary Diversity The frequency of consuming different food groups by the mothers in control and intervention groups during the previous day and night is shown in Table 27. It can be seen that the cereals and beans groups are those that are most consumed by almost all of the mothers, followed by milk products, fats, non vitamin A rich fruits or vegetables, sweets, iron fortified food, eggs and meats. There is no difference between intervention and control groups.

For the purpose of exploring maternal dietary diversity we have grouped the foods into 9 food groups. This is based on recent work by FANTA, IFPRI and others who have been exploring indicators for maternal dietary quality through the analyses of different data sets of dietary intakes of various developing countries and have found a relationship between number of these food groups and mean micronutrient adequacy (MMA) (M Arimond et al. 2009). These authors have explored indicators using 9, 11, 13 and 21 food groups and we have used the 9 food grouping for this exploration as listed below as this most lends to the food group data in this survey. It is important to note that these food groups reflect micronutrient intakes and so do not include the food groups of fats or sweets and sugar. The 9 food groups for analysis (letters show the grouping of the food groups listed in the questionnaire) are the following:
- All starchy staples: aa, bb - All Legumes and nuts: dd - All dairy: ll - Organ meat: hh - Eggs: kk - Other animal source foods: ii, jj - Dark green leafy vegetables: ee - Other vitamin A-rich fruits and vegetables: cc, ff - Other fruits and vegetables: gg
Tables 28 and 29 show the frequency of number of food groups (of the total of 9 for MMA) and the mean and median number of these food groups consumed by the mothers
in the study. The mean number of food groups consumed is 4 and the distribution is similar between control and intervention groups.

Due to the practice of maternal dietary restriction during the first month after birth the number of food groups consumed by mothers with infants in this age group is compared to all other mothers. Table 30 shows that in fact mothers with babies under 1 month receive a significantly lower number of food groups than the other mothers, showing that dietary diversity is less during this period.

In the analyses by Arimond et al. 2009, statistical relationships with MMA were found to be strongest with cut off points of 4 or 5 of the above 9 food groups. Thus we present the proportion of mothers in this study that consume 4 or more and 5 or more of these food groups using the following formula. Mothers who received foods from >4 (or 5) food groups during the previous day x 100 ______________________________________________________________________

It is important to note that this is an exploratory indicator of maternal dietary diversity and thus no conclusions can be drawn. Yet it is interesting that only 58% of the mothers meet the 4 or more food group intake and 30% of mothers consume 5 or more food groups (Table 31). Nevertheless these indicators can be used to compare maternal dietary diversity before and after the intervention. On the suggestion of Mary Arimond (personal communication) we have calculated 2 further indicators: i) a score for the total number of animal products groups (hh, ii, jj, kk, ll including milk, giving a maximum total score of 5) and ii) a score for the total number of vegetable and fruits groups (ee, ff, gg, cc, giving a maximum score of 4). Table 32 shows that the mean scores amongst mothers in this population is low with a median of only 1 food group out of a possible 5 for animal products and similarly 1 out of 4 for possible vegetable products. This is the same for both intervention and control groups.

Nearly half of the population of mothers (45%) consumed and iron rich food or iron fortified food, the same proportion in control and intervention groups as shown in table 34. DISCUSSION The objective of this survey is to provide cross-sectional baseline data of IYC and maternal feeding indicators, IYC nutritional status and health practices to design and be able to evaluate the education interventions to improve infant and maternal feeding practices and nutritional status of the IYC in these Nicaraguan communities. The base-line data provides information on current practices which allows the selection and design of the intervention content and serves as comparison with a final evaluation using similar criteria. This baseline data also serves to describe these conditions in the control
population to assure that it is comparable with those who will receive the intervention and allows the evaluation of changes that can be attributed to the intervention. The population characteristics described in this baseline survey are similar between intervention and control communities. The nutritional status data of these populations show growth patterns typical of many developing countries, especially in Latin America (LA). Height-for age Z-scores and prevalence of stunting is low at 0 – 6 months but rapidly increases to 30% during the second year using the WHO reference standards. This is a high prevalence, higher than the national average for Nicaragua, and higher than several countries of LA, although less than other Central American countries such as rural Guatemala. When the NCHS standards are used, prevalence of stunting and other under nutrition indicators are lower, as found in other countries, due to the different growth patterns between predominantly breastfed and formula fed children. Although most countries have adopted the new WHO 2006 reference standard, both standards are frequently used for purposes of comparison with information from previous years and because reported national prevalence of stunting is lower with the NCHS standards. For the majority of the anthropometric variables and prevalences of under- nutrition there are similarities between control and intervention populations, indicating that this is a comparable population for nutritional status. The prevalence of overweight and obesity is low in this population using either reference standards, similar between intervention and control groups and tends to decrease with age. Most of the infant feeding practices described are similar between intervention and control groups, indicating that these are comparable populations. Early infant feeding practices show that the majority of infants breastfeed and 75% within the first hour. However the introduction of liquids during the first 3 days is not uncommon. These are practices that need to be addressed in the intervention. Exclusive breastfeeding dropped from 80% in the first month to 26% 4 – 5 months with introduction of cow’s milk, fresco and waters during this time. This level of exclusive breastfeeding is low and needs to be addressed in the intervention. The process of introduction of complementary foods is similar between intervention and control groups. Foods are timely introduced according to the indicator 6 – 8 months but the quality of the complementary food given is inadequate as shown by the low dietary diversity; only half of the children met the minimum dietary diversity. More children met the minimum feeding frequency requirement but only 35% met the minimum acceptable diet, thus both feeding frequency and a more diverse diet need to be addressed in the intervention. Iron intake is low in the Nicaraguan population (Mora 2007) and sources of iron in the diet need to be addressed. The proportion of children consuming iron rich foods is low, only 18% consumed a meat product and 23% an iron fortified foods. Ways to increase iron rich foods need to be addressed in the intervention. Health care and child health indicators were mostly similar between intervention and control groups. Prevalence of diarrhoea and cough are high amongst the children and feeding during illness needs to be addressed in the intervention. Attendance for growth monitoring sessions needs to be encouraged. Mothers receive information about child feeding from a variety of sources; thus consistency in messages needs to be addressed in
the intervention with especial attention to health personnel who are important credible sources of advice. Dietary diversity of the mothers’ diet is low and especially for animal sources (median score 1/5) and vegetable and fruits (median score 1/4). This is especially low during the first month after giving birth. However, the dietary diversity of the mothers may be higher than with the children although different criteria for calculation of these are used (9 food groups for the mothers, 7 food groups for the children). Strategies to increase dietary diversity in both mothers and children need to be sought for the intervention. REFERENCES Arimond M. et al. 2009.
