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.

Recommended school policies are associated with student sugary drink and fruit and vegetable intake.
To examine the association between 8 recommended school obesity-related policies and student behaviors and weight in a cohort of Minnesota schools. ⋯ Students attending schools that added recommended policies to promote healthy eating showed improved dietary behaviors, independent of secular trends compared with students in schools that did not add recommended policies.

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.

ReviewThe obesity paradox: understanding the effect of obesity on mortality among individuals with cardiovascular disease.
To discuss possible explanations for the obesity paradox and explore whether the paradox can be attributed to a form of selection bias known as collider stratification bias. ⋯ Results demonstrate that collider stratification bias is one plausible explanation for the obesity paradox. After conditioning on CVD status in the design or analysis, obesity can appear protective among individuals with CVD.

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.
