Physical activity and incident diabetes mellitus in postmenopausal women

Am J Public Health. 2000 Jan;90(1):134-8. doi: 10.2105/ajph.90.1.134.


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.
