Introduction: Sexual health education is crucial in reducing the burden of STIs among young adults. Comprehensive sexuality education can lead to positive risk reduction outcomes, such as delayed initiation of sex, a decreased number of sexual partners and frequency of sex, and increased use of contraceptives. The purpose of this study was to…

Background: Knowledge of specific health-related events encountered by students studying abroad and the availability and use of pre-travel healthcare for these students is lacking. Methods: Anonymous web-based questionnaires were sent to study abroad offices, student health centers, and undergraduate students after studying abroad at eight…

Background: Due to the risk of cross-contamination and the enforcement of strict infection control guidelines, patients with cystic fibrosis (CF) and their families have engaged in social and physical distancing for the past decade and a half. Family members, such as parents, are considered to be a critical component of patients' lives. Objective:…

Narratives have been widely acknowledged as a powerful persuasion tool in health promotion and education. Recently, great efforts have been devoted to identifying message components and causal pathways that maximize a narrative's persuasion power. Specifically, we investigated how narrator point of view and readers' subjective relative risk…

Objective: The present study focuses on factors that predict sexual risk behaviors and sexual health screening behaviors in a sample of university students in Lebanon. Participants: A convenience sample of 250 undergraduate students was recruited at a private university in Beirut, Lebanon. Methods: Students completed measures of religiosity,…

Risk of bias (RoB) assessments are a core element of evidence synthesis but can be time consuming and subjective. We aimed to develop a decision rule-based algorithm for RoB assessment of seroprevalence studies. We developed the SeroTracker-RoB algorithm. The algorithm derives seven objective and two subjective critical appraisal items from the…

Dengue, Zika and Chikungunya arboviruses (DZC), mainly transmitted by mosquito "Aedes aegypti," are global health public issues affecting 390 million people each year. In most endemic countries, vector control strategies have been focused on reducing breeding sites and adult mosquito populations. Most health communication strategies have…

In this article, we suggest that aging and development are two sides of the same coin, and that developing a comprehensive understanding of health and disease risk requires examining age-related processes occurring throughout the earliest years of life. Compared to other periods in life, it is during this early period of acute vulnerability, when…

Objective: To examine how in-person classroom instruction was related to risk of SARS-CoV-2 infection in undergraduate students. Participants: Indiana University undergraduate students (n = 69,606) enrolled in Fall 2020, when courses with in-person and remote instruction options were available. Methods: Students participated weekly in mandatory…

Objective: This longitudinal study tested the relationship between cigarette and e-cigarette use and SARS-CoV-2 seroconversion among US college students. Participants: Undergraduate students (n = 764), drawn from a randomly selected invitation-only pool from a large Midwestern university, that were initially negative for SARS-CoV-2 antibodies and…

Limited research has been done among pregnant people participating in investigational drug trials. To enhance the ethical understanding of pregnant people's perspectives on research participation, we sought to describe motives and risk perceptions of participants in a phase 1 trial of ledipasvir/sofosbuvir (LDV/SOF) treatment for chronic Hepatitis…

The association between autism spectrum disorder (ASD) and subsequent sexually transmitted infections (STIs) and the potential effects of medications on STI risk remain unknown. In all, 5076 adolescents and young adults with ASD and 57,060 age-/sex-matched individuals without ASD were enrolled between 2001 and 2009 and followed-up to the end of…

The COVID-19 pandemic has forced children to reckon with the causal relations underlying disease transmission. What are children's theories of how COVID-19 is transmitted? And how do they understand the relation between COVID-19 susceptibility and the need for disease-mitigating behavior? We asked these questions in the context of children's…

Background: Tobacco use is known to worsen asthma management. No studies have investigated how trends in youth tobacco use and related harm perceptions vary by asthma status and sex. This study examined these trends among Florida high school students during 2012-2018. Methods: Data from the 2012, 2014, 2016, and 2018 Florida Youth Tobacco Survey…

The proportion of infants in the United States who are breastfed at 1 year remains well below the Healthy People 2030 target. The health implications of suboptimal breastfeeding durations are significant, including increased risk of childhood leukemia and maternal Type 2 diabetes. Prenatal breastfeeding education provides an opportunity to improve…
