Does later school start improve adolescents' sleep and substance use?: A quasi-experimental study.
A later school start time policy has been recommended as a solution to adolescents' sleep deprivation. We estimated the impacts of later school start times on adolescents' sleep and substance use by leveraging a quasi-experiment in which school start time was delayed in some regions in South Korea. ⋯ Our findings suggest that policies that increase sleep in adolescents may have positive effects on health behaviors, but additional efforts may be required to sustain positive impacts over time. Physicians and education and health policymakers should consider the long-term effects of later school start times on adolescent health and well-being.

Associations of educational and marketing messages with beliefs about nicotine and reduced nicotine cigarettes.
Widespread misperceptions about nicotine may have unintended effects on public health. We examined associations between existing messages about nicotine or tobacco and beliefs about nicotine and reduced nicotine cigarettes (RNC). ⋯ Few existing messages improved understanding of the risks of nicotine separately from the risks of combustible products. Communication research is needed to promote greater public understanding of nicotine while minimizing unintended effects on nicotine and tobacco use.

Sex differences in appeal, reward, and sensory experience of E-cigarette flavors among adults who smoke cigarettes.
Flavors enhance nicotine e-cigarette appeal by altering sensory experience. Females may be more sensitive to tobacco-associated cues and uniquely affected by flavor. The current study is an exploratory analysis to examine differences by sex on reward, appeal, and sensory experience of popular e-cigarette flavors. ⋯ Menthol in e-cigarettes may play an important role in mediating appeal and/or reward among females. This may be due in part to their ability to better detect sensory effects of e-cigarettes.

Associations between news coverage, social media discussions, and search trends about celebrity deaths, screening, and other colorectal cancer-related events.
Colorectal cancer (CRC) is the third leading cause of cancer death among both men and women in the United States. CRC-related events may increase media coverage and public attention, boosting awareness and prevention. This study examined associations between several types of CRC events (including unplanned celebrity cancer deaths and planned events like national CRC awareness months, celebrity screening behavior, and screening guideline changes) and news coverage, Twitter discussions, and Google search trends about CRC and CRC screening. ⋯ CRC events provide opportunities to increase attention to CRC. Media and public health professionals should actively intervene during CRC events to increase emphasis on CRC screening and evidence-based recommendations.
