Changes of maternal dietary intake, bodyweight and fetal growth throughout pregnancy in pregnant Japanese women.

Aim: The associations among changes in dietary intake, maternal bodyweight, and fetal growth during the course of pregnancy were investigated in a prospective cohort study carried out on 135 Japanese women.

Material And Methods: Dietary intake was analyzed using digital photos of meals taken over 3 consecutive days, in the first, second and third trimester, and was compared with maternal bodyweight, estimated fetal bodyweight by ultrasound examination, and birthweight.

Results: Surprisingly, the mean total calorie intake remained below 1600 kcal/day during pregnancy, much lower than the value recommended in the 2010 edition of 'Dietary Reference Intakes for Japanese'.
