N1 - Funding Information:
Supported by a National Institutes of Health/National Heart, Lung, and Blood Institute, contract N01-HC-25195, and research grants 2K24HL04334 (R.S.V.), and K23HL074077 (T.J.W.). The funding sources had no role in the design/conduct of the study, management, analysis, and interpretation of data, or the preparation of the manuscript. The National Heart Lung Blood Institute funded the collection of data on height and weight (NO1-HC-25195) used in this investigation, and approved the manuscript. Dr. Vasan had full access to all of the data in the study and takes responsibility for the integrity of and the accuracy of the data analysis.

N2 - Purpose: We evaluated trends in the incidence of overweight and obesity over the past 50 years. Methods: We evaluated trends in the incidence of overweight (25 ≤ body mass index [BMI] <30 kg/m2), obesity (BMI ≥30 kg/m2) and stage 2 obesity (BMI ≥35 kg/m2) from 1950 to 2000 in Framingham Study participants (n = 6798, 54% women). Individuals aged 40-55 years who attended 2 examinations 8 years apart in each decade were eligible. Results: The incidences of overweight, obesity, and stage 2 obesity increased across the decades in both sexes (P for trend <.001). For men, the incidence of overweight rose from 21.8% (95% confidence interval [CI], 17.6-26.5) in the 1950s to 35.2% (95% CI, 28.6-42.5) in the 1990s; of obesity from 5.8% (95% CI, 4.4-7.6) to 14.8% (95% CI, 12.2-17.9); and of stage 2 obesity from 0.2% (95% CI, 0.1-0.9) to 5.4% (95% CI, 4.0-7.2). For women, incidence rates of overweight increased from 15.0% (95% CI, 12.3-18.1) to 33.1% (95% CI, 29.0-37.4); of obesity from 3.9% (95% CI, 2.9-5.3) to 14% (95% CI, 11.6-16.7); and of stage 2 obesity from 1.7% (95% CI, 1.1-2.6) to 4.4% (95% CI, 3.2-6.0). Overall, incidence rates of overweight increased 2-fold and that of obesity more than 3-fold over 5 decades, findings that remained robust upon additional adjustment for baseline BMI in each decade. Conclusions: The incidence of overweight and obesity increased progressively over the last 5 decades, suggesting that the rising trend in prevalence is not a recent phenomenon.
