Wu F, Juonala M, Sabin MA, et al. - Researchers conducted this population‐based cohort study to explore whether a longer duration of overweight or obesity from youth to adulthood is correlated with multiple cardiometabolic outcomes in adulthood and if this connection is independent of adult adiposity. The sample consisted of 1,268 youths, aged 3 to 18 years, with follow‐ups at 3, 6, 9, 12, 21, 27, and 31 years. Duration of overweight or obesity over a 31‐year follow‐up has been estimated. Data reported that overweight/obesity rates were 7.9% at baseline and 55.9% after 31 years. Longer duration of overweight or obesity was linked to increased risk of all outcomes after adjustment for confounders. When the body mass index was further adjusted, such affiliations vanished or were significantly reduced. Overweight or obesity in adulthood seems to be more important for adult cardiometabolic health than childhood.
