Résumé :	[BDSP. Notice produite par INIST-CNRS LtEFR0xC. Diffusion soumise à autorisation]. Objectives : We described changes in body mass index (BMI) and the prevalence of thinness among young Japanese women (aged 15-29 years) from 1976 to 2000 by reanalyzing the nationwide data in the National Nutrition Survey, Japan. Methods : We used height and weight data sets for 30903 non pregnant, non-lactating women during the 25-year period. We calculated the mean values of BMI and the prevalence of thinness for 3 age groups (15-19,20-24, and 25-29 years of age). Results : Changes in BMI per 10 years were - 0.17 kg/m2, - 0.22 kg/m2, and - 0.34 kg/m2 for each age group, respectively. Extreme thinness (BMI<17 kg/m2) increased from 2.4% in 1976-1980 to 4.2% in 1996-2000. Conclusions : Further studies regarding topics such as increased smoking prevalence are needed to identify the underlying causes of increasing thinness.
