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.

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.

Pneumococcal vaccination of the elderly during visits to acute care providers: who are vaccinated?
Many elderly remain unvaccinated against invasive pneumococcal disease yet frequently visit acute care providers where they have an opportunity to receive the pneumococcal vaccine. We describe factors associated with pneumococcal vaccination in adults aged 65 years and older during visits to acute care providers. ⋯ Acute care visits were associated with greater pneumococcal vaccine uptake for the elderly during the annual influenza season and long hospital stays.

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.

Review Meta AnalysisImproving diet and physical activity to reduce population prevalence of overweight and obesity: an overview of current evidence.
The aim of this study is to provide an overview of interventions to reduce or prevent overweight or obesity and improve diet or physical activity. ⋯ Various individually targeted interventions were shown to reduce body weight, although effect sizes were typically modest, and the durability of effects has been questioned. New approaches to evaluating population-based interventions, such as taxes and regulation, are recommended. Future research modelling the long-term effects of interventions across the lifespan would also be beneficial.
