Type 2 DiabetesThe increased risk of
diabetes as weight increases has been shown by prospective studies in Norway(7), the United
States (8), Sweden (9), and Israel (10). More recently, the Nurses' Health Study,
using data based on self-reported weights, found that the risk of developing
type 2 diabetes increases as BMI increases In recent studies, the development of type 2 diabetes has been found to be associated with weight gain after age 18 in both men (82) and women (81). The relative risk of diabetes increases by approximately 25 percent for each additional unit of BMI over 22 kg/m2 (83). Additionally, in a prospective study representative of the U.S. population, it was recently estimated that 27 percent of new cases of diabetes were attributable to weight gain in adulthood of 5 kg (11 lb) or more (84). Both cross-sectional (85-87) and longitudinal studies (82, 88, 89) show that abdominal obesity is a major risk factor for type 2 diabetes (82, 87). |
