BMI distribution changes in adolescent British girls.

摘要

Body mass index (BMI) distribution changes were assessed in 2547 relatively affluent English girls, aged 12-16 years, during the UK childhood obesity epidemic (1986-96). An increase in BMI variability was observed only in 12-14 year olds, suggesting that BMI changes for population subgroups were complex, and inconsistent with a generalised increase in BMI.
