Who was studied1,948 people followed from childhood to midlife, 36 years
What changedAdvanced heart, kidney and metabolic problems were more common with higher cumulative body mass index (odds ratio 2.18 per standard-deviation increase)
The catchBMI variability relied on eight measurements over 36 years, potentially missing fluctuations between visits
