Abstract:
Objectives To investigate the correlation between dietary fatty acids intake of pregnant women and neonatal anthropometry at birth. Methods Women in early pregnancy were recruited with appropriate value of weight gain in pregnancy. Instant photography was used to assess the dietary situation in both the second trimester and the third trimester to calculate the intakes of food, energy, macronutrients, and fatty acids. The body weight, height and BMI at birth were evaluated with Z scores. The correlation between dietary fatty acids of pregnant women and neonatal anthropometry at birth were analyzed. Results There were 516 pregnant women recruited in this study. The average intakes of polyunsaturated fatty acids (PUFA) and the proportion of total fatty acids in the two trimesters were 15 . 09 g/d, 23 . 93% and 17 . 18 g/d, 24 . 86%. In the second trimester the intakes of n-6 and n-3 PUFA were 14 . 23 g/d and 3 . 45 g/d, and in the third trimester, n-6 and n-3 PUFA were 16 . 08 g/d and 3 . 81 g/d, the average intakes in the third trimester were signiifcantly higher than those in the second trimester (P??0 . 05 ). The intake of DHA ( 64 . 43 mg/d) in the second trimester was lower than that in the third trimester 75 . 12 mg/d, (P??0 . 05 ).The dietary intakes of n-3 PUFA, n-6 PUFA and n-6/n-3 ratio in the second trimester were positively correlated with neonatal BMI r=0 . 142~0 . 189 , P??0 . 05 ). Conclusions The dietary ratio of n-6/n-3 PUFA in the second trimester was positively correlated with neonatal BMI, suggesting that moderately increasing the intake of n-3 PUFA may play a positive role in reducing childhood obesity.
