Habitual exercise may amplify the respiratory uptake of air pollutants in the lung, exacerbating the adverse effects of air pollution. However, it is unclear whether this can reduce the health benefits of habitual exercise (referred to as leisure-time exercise). Thus, the combined effects of habitual exercise and chronic exposure to ambient fine particulate matter 2.5 on cardiovascular mortality were examined among adults in Taiwan. ⋯ High level of habitual exercise combined with low exposure level of ambient particulate matter 2.5 is associated with the lowest risk of cardiovascular death. A higher level of habitual exercise is associated with a lower risk of cardiovascular death at all levels of particulate matter 2.5 exposure studied. The results indicate that habitual exercise is a safe health promotion strategy even for people residing in relatively polluted regions.

New warning labels for alcohol could reduce alcohol-related health harms. This study examined consumer responses to alcohol warnings with different designs. ⋯ New alcohol warnings could discourage alcohol consumption, especially if warnings include icons.

Prepared (ready-to-eat) foods are sold in >90% of U.S. supermarkets, but little is known about their nutritional quality. This study examined trends in purchases of supermarket prepared foods and compared their nutritional profile with that of supermarket packaged foods and restaurant foods. ⋯ Supply of and demand for supermarket prepared foods have grown substantially over time. These trends are concerning given these foods' overall poor nutritional quality.

Among individuals with chronic respiratory conditions, transitions between patterns of tobacco product use are not well understood. This study examines how transitions, including quitting altogether, differ over time between those who do and do not have chronic respiratory conditions. ⋯ Although combustible tobacco use negatively impacts the management and prognosis of respiratory illnesses, combustible tobacco users who were recently diagnosed with a chronic respiratory condition were not likely to quit using tobacco. Efforts to encourage and support cessation in this medically vulnerable population should be increased.

The purpose of this study was to describe the proportion of U.S. adults who support, oppose, or are neutral toward a policy designating R-ratings for movies depicting cigarette smoking and to identify predictors of policy opposition or neutrality among a nationally representative sample. ⋯ Study findings show that a near majority of U.S. adults support a policy that would designate R-ratings for movies depicting cigarette smoking and that there is greater neutrality than opposition toward the policy. Assessing public opinion toward a policy designating R-ratings for movies depicting cigarette smoking may inform efforts to educate the public about the value of such policies for preventing youth tobacco initiation.
