Background – as of 2011

Inappropriate feeding practices during the complementary feeding

period contribute to inadequate nutrient intake among infants &

young children

Even when food resources are available in the home, caregivers are

not able to make the best use of them:

Inadequate knowledge

Unhealthy beliefs & practices

Inappropriate advice

Need for interventions to improve quality of complementary foods by

promoting consumption of a variety of foods, including local foods

Lack of evidence!

Page 4: Impact of Food Security Interventions and Nutrition Education on Child Dietary Diversity

IFSN Project

To improve food security & nutrition:

• Support to joint nutrition education between Agriculture and Health

for increased impact of knowledge and skills on: production,

processing, storage and utilization including improved

complementary feeding practices

• Distribution of a range of agricultural inputs to vulnerable

households including those with young children and pregnant

women

• Increased diversification of local production to include different

livestock and nutritious food crops covering the six food groups

Page 5: Impact of Food Security Interventions and Nutrition Education on Child Dietary Diversity

Key Activities

5

Promote diversified agriculture to improve availability, access and utilization of all six food groups

Capacity building of farmers, lead farmers, frontline staff

Promote income generating activities: fruit trees, apiary, mushrooms, vegetables, cassava, Irish potatoes, orange-fleshed sweet potatoes

Promotion of environment, soil & water conservation

Improve water & sanitation

Promotion of small scale irrigation-gravity fed, treadle pumps, residual moisture

Page 6: Impact of Food Security Interventions and Nutrition Education on Child Dietary Diversity

Objectives of the Research Project …

… was to test the following hypotheses:

1. TIPs formative research generates behaviour

change communication messages & nutritionally

improved recipes that lead to lasting improvements in

complementary feeding practices, dietary intakes &

child nutritional status

2. Locally available & affordable foods can provide a

significant contribution to the nutritional requirements of

children 6-23 months6

Page 7: Impact of Food Security Interventions and Nutrition Education on Child Dietary Diversity

3. Nutrition education with focus on IYCF & linked with

a food security intervention can improve child

feeding practices & nutritional status, &

4. Using locally available foods for improving

complementary feeding practices & children’s nutrition

status is a sustainable strategy, which can be

replicated by households at low cost & taken to scale

using available Government services.

Primary outcome indicator: change in length of children

Secondary outcome indicators: achieved Minimum Dietary Diversity (MDD) among children achieved Minimum Meal Frequency (MMF) among children improved caregiver’s knowledge, attitudes & feeding, hygiene & food

safety practices

Enrolment criteria:

Caregivers with children 6-9 months at first assessment

Intervention area: member of FAO nutrition education group

Control area: resident in FAO intervention villages; matched by sex &

age in days (±14 days)

Assessments: every 3 months for one year = five assessments

Cross-sectional SurveysBaseline, Mid-term, & Impact

• Cross-sectional nutrition surveys in 24 EPA sections in Kasungu & Mzimba Districts

• Study population: mothers/primary caregivers and children <2 years

• Random selection of 3 villages on section (cluster) level (PPS) (baseline and mid-term)

• Random selection of 4 villages per section (PPS) (impact)

• Random selection of participants at village level

Page 11: Impact of Food Security Interventions and Nutrition Education on Child Dietary Diversity

11

• Baseline: August/September 2011 (sample size: height-for-age z-score)– IFSN intervention villages

• Mid-term: August/September 2013 (sample size: children’s dietary diversity)– Intervention area: nutrition education villages only (Round 1)– Control area: food security intervention villages only

• Impact: August/September 2014 (sample size: height-for-age z-score)

– Intervention area: nutrition education villages only(Round 1, same as in mid-term + 1 additional per section)

– Control area: food security intervention villages only

Impact on Height-for-age Z-score (DiD)Midterm Survey & Impact Survey

• Midterm Survey: Sign. differences in mean

HAZ between intervention (-0.17) & control (-

0.19) which can be related to the intervention:

food security & nutrition education

• Impact Survey: No sign. differences in mean

HAZ between intervention (-0.17) & control (-

0.18)

Conclusions

• Food security interventions & participatory

nutrition education improved children’s

nutritional status at community level

• IFSN nutrition education approach using

local resources has a high potential to

improve dietary diversity of children
