Flooding and elevated prenatal depression in a climate-sensitive community in rural Bangladesh: a mixed methods study.

Background: Prenatal depression can have lasting adverse impacts on child health. Little is known about the impact of floods on prenatal depression in low- and middle-income countries.

Methods: We conducted a cross-sectional survey of 881 pregnant women from September 24, 2023 to July 19, 2024 in riverine communities in rural Bangladesh.

The Role of Information Avoidance in Managing Uncertainty from Conflicting Recommendations about Electronic Cigarettes.

Insufficient scientific evidence about electronic cigarettes (e-cigarettes) has led to conflicting recommendations (CRs) by credible scientific organizations, creating a public health debate that could prove especially difficult to reconcile as current and former smokers make decisions about whether to use e-cigarettes. To investigate how CRs about e-cigarettes may affect intentions to engage in healthy behaviors, 717 former and current smokers were randomly exposed to one of five conditions (varying in the level of conflict in recommendations) in this between-subject experiment. Our results indicated a significant interaction between the message level of conflict and individuals' information avoidance, employed to maintain hope and deniability.

Leveraging immersive technology to expand access to opioid overdose reversal training in community settings: Results from a randomized controlled equivalence trial.

Background: Immersive video (e.g. virtual reality) poses a promising and engaging alternative to standard in-person trainings and can potentially increase access to evidence-based opioid overdose prevention programs (OOPPs).

Support or competition? How online social networks increase physical activity: A randomized controlled trial.

To identify what features of online social networks can increase physical activity, we conducted a 4-arm randomized controlled trial in 2014 in Philadelphia, PA. Students (n = 790, mean age = 25.2) at an university were randomly assigned to one of four conditions composed of either supportive or competitive relationships and either with individual or team incentives for attending exercise classes.
