Comparative effectiveness of strategies to prevent weight gain among women with and at risk for breast cancer: a systematic review.

Background: Obesity affects cancer risk and treatment outcomes. Preventing weight gain may prevent some cancers, improve cancer outcomes, reduce cancer recurrence and increase cancer-related survival. We performed a systematic review to identify strategies to prevent weight gain in individuals with or at risk for breast cancer.

Ethnic-specific determinants of exercise capacity in a healthy high-risk population.

Purpose: African Americans (AA) have been shown to have lower exercise capacities and a higher prevalence of related risk for cardiovascular disease (CVD) compared to European Americans (EA). Broad biopsychosocial models that may inform the design of ethnic-specific exercise programs have not been well examined. We thus examined exercise capacity and its biopsychosocial correlates in a healthy population of AA and EA at increased risk of CVD.
