Physical activity and incident diabetes mellitus in postmenopausal women
Abstract
Objectives: This study determined whether the incidence of diabetes is reduced among physically active older women.
Methods: We assessed physical activity by mailed questionnaire and 12-year incidence of diabetes (ostensibly type 2 diabetes) in a cohort of 34257 women aged 55 to 69 years.
Results: After adjustment for age, education, smoking, alcohol intake, estrogen use, dietary variables, and family history of diabetes, women who reported any physical activity had a relative risk of diabetes of 0.69 (95% confidence interval = 0.63, 0.77) compared with sedentary women.
Conclusions: These findings suggest that physical activity is important for type 2 diabetes prevention among older women.
