Population-based study demonstrates shifting childhood obesity trends and identifies critical onset windows in youth, highlighting key developmental targets for prevention.

Key Points

To evaluate 30-year cross-sectional and longitudinal trends in obesity prevalence and identify critical ages of obesity onset among Japanese youth aged 5 to 17 years.
Analyzed nationwide population-based data from the Annual Reports of the School Health Survey in Japan from 1978 to 2007.
Defined obesity as a body mass index at or above the 95th percentile for age and sex using 1979 to 1981 Japanese reference cohorts.
Cross-sectional assessments showed obesity prevalence peaked in the late 1990s to early 2000s and gradually declined thereafter across most age groups, with the exception of 17-year-old boys.
Longitudinal tracking identified late infancy (ages 5 to 6 years) as a critical onset window for both sexes, with an additional critical period occurring during high school for boys.
