[[alternative]]A prospective study of maternal nutrient intakes on infant anthropometric outcomes

[[abstract]]The purposes of this study are to collect and evaluate mother’s dietary information during pregnancy and to examine the effects between maternal diet and newborn outcomes including weight, height, and head circumference. We recruited health pregnancy women less than 20 weeks from Taipei Municipal Women’s and Children’s Hospital. We collected data including mother’s general characteristics, dietary information, anthropometry assessment and newborn outcomes by face-to-face and telephone interview. The SPSS 11.0 software package was used for all statistical analyses. The study initially recruited 151 pregnant women to participate, there were 11 dropped out until delivery, therefore the final analyses included 140 women and their newborn. Before pregnancy, the subjects’ average age was 30.2 years old, weight was 53.4 kg, and BMI was 21.0 kg/m2, total gestational weight gain was 14.2 kg. Newborns’ average gestational age was 38.7 weeks, birth weight was 3166 g, height was 49 cm, and head circumference was 34 cm. By 24 hour recall the women’s three trimesters energy intake were 1861 Kcal, 1971 Kcal and 2163 Kcal, respectively. The percentage of energy was 52% of carbohydrate, 15% of protein and 33% of fat. We found gestational age, gestational weight gain and BMI before pregnancy were positively correlated with newborn outcomes (p<0.05), but mother’s age, educational years, children’s number, family incomes, family social-economical status and father’s educational years had no correlation with newborn outcomes. During pregnancy, mother’s vitamin B12 nutrition density intakes was positively correlated with newborn height (p<0.05), but vitamin A, vitamin C, folate, potassium and dietary fiber had negative correlations (p<0.05). Mother’s nutrition density intakes including vitamin B1 and zinc were positively correlated with newborn weight (p<0.05), but vitamin A, vitamin B2, vitamin C, folate, potassium, iron and dietary fiber had negative correlations (p
