Introduction

Factors interacting with child development• Breastfeeding period• Gestational age• Birth weight

The breastfeeding period

Benefits: The main source of nutrition[2,4,5] Immune function and protection for diseases[3,4,5] Prevent the obesity [1] baby Physical and mental development[4,5] Uterine shrinkage Decrease the risk of: Breast cancer Osteoporosis mother[5] Depression Protection for metabolic syndrome

The gestational age

The preterm babies have a higher risk of:• Lung function abnormalities[8,9]• Cognitive deficit[8,9]• Metabolic disorders[7]• Cardiovascular or renal diseases[8,9]• Higher blood pressure[9]• Infectious diseases[6,8,9]• infant mortality and morbidity[6]

Discussions

Epidemiological evaluation of factors influencing growth should be an important public health issue

Breastfeeding according to WHO recommendation is still a problem in Romania – according the latest studies developed by WHO that showed a rate of exclusive breastfeeding about 16% in our country in 2010 but now we obtained a rate of breastfeeding of 33.30%

The incidence of low birth-weight after WHO was 9% in 2001,and we’ve obtained 8.65% in our study

About the age of the onset of puberty compaired to WHO that obtained a result between 10-11 years for girls and 11-12 years for boys in 2012 that was my reference,and the mean age that we discovered 10.26+1.58 girls and 10.35+1.6 boys show that it’s not lowered

Conclusions

1. There is an improvement in the percentage of children breastfed according to WHO recommendations,with the mention that we had data about exclusive breastfeeding in earlier studies and now we can’t tell if the children were exclusive breastfed2. The incidence of low birth weight is about the same as the last evaluation available from the WHO. 3. The age of onset of puberty has not lowered in our country, compared to the global tendency
