Outline of Final Research Achievements

It has been well established that prenatal and postnatal nutritional status would give long-term effects on some physiological functions and risk of diseases. In this study, we showed that prenatal undernutrition alter the relationship between gonadal hormone and metabolic function in later life and that this alterations would exacerbate the effects of hyperandrogegism on metabolic functions. In addition, we established the experimental animal models which can be used for the evaluation of mechanisms. This study gives some important information in order to evaluate the pathophysiology of polycystic ovary syndrome.

Academic Significance and Societal Importance of the Research Achievements

日本は他の先進国に比べて生殖世代における女性のやせの割合が極めて高く、この状態が本人ならびに次世代の健康状態に及ぼす影響が危惧されている。本研究成果は、妊娠中の低栄養が子供の生殖機能や栄養代謝機能に及ぼすことを明らかにしており、今後生殖世代の女性に対して妊娠前および妊娠中の適切な栄養摂取を推奨する上で重要な知見となり得る。また、これをきっかけとしてやせ願望が蔓延する現在の社会情勢が改善されることが期待される。
