若年女性とその母親を対象とし,母親の痩身志向が次世代の健康に与える影響について,意識調査と発育記録をもとに検討した。対象者の在胎週数は39.3週,出産までの母体重の増加量は10.0kg, 新生児の出生体重は3,108gであった。低出生体重児は5名(6.0%)出現したが,指標として示したKaup指数をはじめ若年女性のBMIおよび体脂肪率に母親の痩身志向の有無による差は認められなかった。胎児の在胎週数は37.8週を超える正規産であるが,低出生体重児の在胎週数は3,000グラム以上の出生体重児と比較して有意に短かいことが認められた。しかし,母体重増加量は他の群と比べ最も増加していた。低出生体重児が成長した現在のBMIは,BMI区分では正常であるが,体脂肪率は30%を超える「隠れ肥満」であり,他の群と比べて有意に高かった。若年女性のやせが著しく増加し,妊娠した時点で低栄養状態にある母親が増えている。健康の一次予防の観点から,母体の健康および体重管理の重要性が示唆された。The effect of a desire for slenderness among mothers on the health of their daughters was investigated in these young women and their mothers based on awareness survey results, as well as child development records. Subject pairs had the following average characteristics : daughters were born at a gestational age of 39.3 weeks with a neonatal birth weight of 3,108g and mothers had gestational weight gain of 10.0kg up to delivery. Although a total of five daughters (6.0%) born as low birth weight infants were included, no differences were observed on indices including the Kaup index, BMI, and body fat percentage in daughters of mothers with and without a desire for slenderness. Gestational ages (weeks) in the group of low birth weight infant were an average of 37.8 weeks, and ages were significantly shorter in the group of less than 2,500g in body weight than the group of more than 3,000g. But gestational weight gain was greater in the group of low birth weight infants than the other groups. It appeared that emaciation of young women increases remarkably, and the lower nutrition state in mothers increases at the time that they become pregnant. Current percentage of body fat in the group of low birth weight infants was greater than the other groups, although BMI in the group of low birth weight infant were "common" in the BMI category. From the viewpoint of primary prevention of adult diseases, the importance of the nutrient balance and body weight control in gestation has been clarified
