Abstract Aim Mid-life obesity is associated with T2D risk. However, less is known about the cumulative effect of obesity during adulthood. Methods Framingham Offspring Study participants who had an examination at 35 ± 2 years and were initially free of T2D were included in this study (N = 1026). A cumulative excess weight (CEW) score (year*kg/m2 ) was calculated until T2D diagnostic or the end of follow-up. Results Eighty-four individuals (8.2%) developed T2D over 20 ± 6 years. Mean CEW scores were 118.0 ± 114.6 year*kg/m2 in individuals who developed T2D and 30.2 ± 91.4 year*kg/m2 in those who did not develop T2D ( P < 0.01). T2D risk was doubled for each standard deviation increase in the CEW score (OR = 1.99 [1.64-2.40]; P < 0.001). However, CEW score was only significantly associated with T2D incidence for participants with a baseline BMI < 25 kg/m2 (OR = 2.13 [1.36–3.36]; P < 0.001). Conclusions Accumulating weight between the mid-thirties to the mid-fifties increases the risk of developing T2D. However, BMI in mid-thirties remains a stronger predictor of T2D risk.
