While the health benefits of meeting moderate/vigorous-intensity physical activity (MVPA) guidelines have been well established, the health risks of sedentary behavior, independent of meeting MVPA guidelines, are becoming evident. Sedentary behavior may require different interventions, based on correlates that differ from MVPA. The current review aimed to collect and appraise the current literature on correlates of sedentary behaviors among adults. ⋯ Results point to the high specificity of various sedentary behaviors (e.g., TV viewing vs sitting and socializing), suggesting that the research domain is complex and cannot be considered the simple absence of MVPA. Several sociodemographic and health factors appear reliably linked to sedentary behavior, yet there is an obvious absence of research focused on cognitive, social, and environmental factors that could be of use in anti-sedentary behavior interventions.

Most studies use age as a cutoff to evaluate screening mammography utilization, generally examining screening up to age 75 years (the age-cutoff method). However, many experts and guidelines encourage clinicians to consider patient health and/or life expectancy. ⋯ Estimating screening mammography utilization among older women can be improved by using projected life expectancy rather than the age-cutoff method.
