Correlates of leisure time physical activity compliance in colorectal cancer survivors.
Physical inactivity is a risk factor for cancer morbidity and mortality, but its influence in colorectal cancer (CRC) survivors is understudied. We investigated sociodemographic, physically limiting, and behavioral predictors influencing leisure time physical activity (LTPA) among CRC survivors. ⋯ Hispanics, non-Hispanic Blacks, those with >2 physically limiting chronic conditions and current smokers warrant additional efforts to encourage physical activity and to determine the impact of regular physical activity on CRC survivorship.

Randomized Controlled Trial Multicenter StudyEfficacy of face masks and respirators in preventing upper respiratory tract bacterial colonization and co-infection in hospital healthcare workers.
We compared the efficacy of medical masks (MM) and N95 respirators (N95) in preventing bacterial colonization/infection in healthcare workers (HCWs). ⋯ N95 respirators were significantly protective against bacterial colonization, co-colonization and viral-bacterial co-infection. We showed that dual respiratory virus or bacterial-viral co-infections can be reduced by the use of N95 respirators. This study has occupational health and safety implications for health workers.

Metabolically healthy obesity: what is the role of sedentary behaviour?
The role of sedentary behaviour in metabolically healthy obesity is unknown. We examined cross-sectional differences in television viewing time across metabolic and obesity phenotypes, hypothesizing that healthy obese individuals spend less time viewing television than their unhealthy counterparts. ⋯ A common type of leisure-time sedentary behaviour varies across metabolic and obesity phenotypes. However, healthy obesity is not explained through differences in leisure-time sedentary behaviour.

Multicenter StudyMen benefit more from midlife leisure-time physical activity than women regarding the development of late-life disability--results of the KORA-Age study.
Encouraging physical activity is an important public health measure to reduce disability prevalence in the aged. The aims of this study were to determine the association between midlife physical activity and late-life disability and to investigate gender-specific differences. ⋯ Elevated physical activity reduces the risk of becoming disabled and postpones the onset of disability by several years, but we could not show an effect on the severity of disability. In addition, men seem to benefit more from leisure-time physical activity than women.

Supplemental Nutrition Assistance Program participation did not help low income Hispanic women in Texas meet the dietary guidelines.
Low-income Hispanic women are at greater risk for dietary deficiencies and obesity. We assessed the association between Supplemental Nutrition Assistance Program participation and dietary intake among 661 Hispanic women aged 26-44 years living in Texas. ⋯ Supplemental Nutrition Assistance Program should play an important role in enhancing the overall dietary quality of low-income households. Policy initiatives such as limiting the purchase of sugar-sweetened beverages and education to enable women to reduce consumption of high sodium processed foods deserve consideration as means to improve the dietary quality of Supplemental Nutrition Assistance Program participants. Effective measures are needed to increase Supplemental Nutrition Assistance Program participation rates among Hispanics.
