Abstract :The purpose of the present study was to elucidate the relationship between the physiological characteristics and nutritional intake of pregnant women and the birthweight of their full-term infants. The women had been recommended a certain gestational weight gain according to their body mass index (BMI) classification. We surveyed 477 pregnant women who provided their consent to participate in the study at three hospitals and one clinic in Okinawa. We performed prenatal check-ups during the second and third trimesters and measured the women’s body weight and ordered blood tests and assessed their nutritional intake status using a brief-type self-administered diet history questionnaire (BDHQ). We obtained the pre-pregnancy BMIs of the women using the World Health Organization (WHO) criteria, and classified the amount of gestational weight gain over the entire pregnancy as either “below,” “within,” or “above” the recommended weight gain as indicated by the Ministry of Health, Lab our and Welfare. The fetal birth weights were divided into four percentile groups(≦10^th percentile, 10-50^th percentile, 50-90^th percentile, and ≧90^th percentile) using the “Gestational age-specific standards for birth size (Revised edition)” created by the Japan Pediatric Society in 2010. We analyzed the associations between the four groups of fetal birth weight and the recommended actual gestational weight gains by the women. An analysis of covariance was performed between the birth weight percentile groups and the nutritional intake, with each recommended gestational weight gain classification, age, and pre-pregnancy BMI as covariates. As a result, with regard to the ratio of consumed energy and energy-producing nutrients, in the second trimester the ratio of carbohydrate energy was significantly lower for women gaining less than the recommended weight (10-50^th percentile) than for those in the 50-90^th percentile group; and significantly higher for those gaining the recommended weight (≦10^th percentile). The ratio of protein and fat energy was significantly higher for the group in the 10-50^th percentile than for that in the 50-90^th percentile. In the third trimester, no significant differences were observed. In the second trimester, increasing staple foods in underweight mothers increased the energy intake from carbohydrates, leading to fetal growth; however, projections suggested that overconsumption of energy from carbohydrates by mothers with normal weights according to the recommendations could lead to fetal birth weights that were small-for-gestational-age.
