Nutrition, Obesity, Pregnancy in AdolescenceAbstract
Nutrition is undoubtedly a factor that determines fetal growth and life after birth. The nutritional status of the mother and its direct effect on the newborn has been widely studied. However, there are indirect pathways that have not been largely explored, such as weight gain during pregnancy. The objective of the study was to evaluate the effect of pre-pregnancy weight mediated by gestational weight gain on the weight of the newborn.
Methodology: Observational Design of a historical cohort.
Data collected from the births of adolescent women were analyzed. Data analysis included descriptive statistics using chi2 and Mann Whitney. Structural equation models were used to evaluate the direct and / or mediated effect of the variables, habitual weight of the pregnant woman (weight prior to pregnancy) and gestational weight gain on the weight of the newborn.
Results: In a direct way, the usual weight of the woman affects the weight of the newborn, so that, for each kilo of maternal increase, the weight of the child increases by 9.7 grams. Additionally, it was found that, for each kilogram of maternal weight gain, the child's weight increased 17.47 grams.
Conclusions: The findings are of great importance, since although starting pregnancy with an adequate maternal weight is important for the well-being of the newborn, this study suggests that the impact of feeding on the process is greater, so directing management strategies Adequate nutrition during pregnancy is essential.
