Outline of Final Research Achievements

The purpose of this study was to determine the effect of maternal carbohydrate intake in early pregnancy on postnatal infant development, using the Longitudinal Study of Maternal and Child Health, a collaborative study initiated in 1988 and still ongoing by the University of Yamanashi Graduate School of Social Medicine and Koshu City, Yamanashi Prefecture. The diet of mothers during the first trimester of pregnancy over a period of about 30 years showed a decrease in the frequency of rice, fruit, seaweed, and seafood intake, and a slight increase in bread and meat intake. The association between maternal carbohydrate intake in early pregnancy and low birth weight (<2,500 g) of the infants was then examined. The percentage of low birth weight infants was 7.6%, and there was no statistically significant association between maternal carbohydrate intake status in early pregnancy and low birth weight of the infants.

Academic Significance and Societal Importance of the Research Achievements

同地域における約30年間という長期間の母親の食事内容の変化を明らかにしたことは日本において数少なく重要な結果であると考える。また、炭水化物摂取状況と低出生体重との検討も、妊婦の食生活は胎児の発育や出生後の児の成長にも影響することから、意義のある研究であったと考える。
