This multiyear, cross-sectional study explores the changes over time in how U.S. middle- and high-school students perceive the harm and addiction risk of E-cigarettes. ⋯ The perceptions of both harm and addictiveness of E-cigarettes have increased over time, independent of current use. Perceptions vary on the basis of age, sex, race/ethnicity, and current use. Efforts should be made to further educate adolescents about E-cigarettes and to regulate their sale and advertisement. Efforts to reduce the uptake of combustible cigarettes among adolescents have been successful and should be duplicated for E-cigarettes.

This paper describes the sources, magnitude, and correlates of missing data in the Behavioral Risk Factor Surveillance System Sexual Orientation and Gender Identity module. ⋯ Missing the Behavioral Risk Factor Surveillance System Sexual Orientation and Gender Identity data is much more prevalent than item nonresponse alone would suggest. Analytic techniques that consider only item nonresponse, such as complete case analysis, risk producing biased findings. Including the Sexual Orientation and Gender Identity module in the required core demographics section is the only feasible method to reduce the amount and complexity of missing data.

In the U.S., universal genotyping of culture-confirmed tuberculosis cases facilitates cluster detection. Early recognition of the small clusters more likely to become outbreaks can help prioritize public health resources for immediate interventions. ⋯ Clusters accumulating ≥3 cases within a year should be prioritized for intervention. Effective response strategies should include plans for targeted outreach to U.S.-born individuals, incarcerated people, those experiencing homelessness, people using substances, and individuals self-identifying as being of American Indian or Alaska Native race or of Black race.

This paper describes the methodology of partial identification and its applicability to empirical research in preventive medicine and public health. ⋯ Partial identification methods are likely to be of considerable interest to clinicians and others engaged in preventive medicine and public health research.

Individuals with noncommunicable diseases account for a disproportionate share of medical expenditures, absenteeism, and presenteeism. Therefore, employers are increasingly looking to worksite wellness programs as a cost-containment strategy. Previous reviews examining whether worksite wellness programs deliver a positive return on investment have shown mixed results, possibly because the more optimistic findings come from studies with poorer methodologic quality. The purpose of this systematic review is to critically revisit and update this literature to explore that hypothesis. ⋯ The highest-quality studies do not support the hypothesis that worksite wellness programs deliver a positive return on investment within the first few years of initiation.
