We evaluate the impacts of small high schools on youth risky behaviors and mental health in New York City, using a two-sample-instrumental-variable approach to address endogenous school enrollment. We find heterogeneous effects. School size, overall, has little effect. Among "students" most likely to attend small schools opened…

Background: Pregnant women are at increased risk of complications from flu, but uptake of flu vaccination is below 75% targets. Evidence suggests that changing illness risk appraisals may increase vaccination behaviour. In 2018-2019, researchers, public health specialists, and pregnant women co-designed a short animation targeting (unhelpful)…

Beginning in 2010, the U.S. Department of Health and Human Services (HHS) sponsored numerous studies testing the effectiveness of Adolescent Pregnancy Prevention programs on youths' risky sexual behaviors. This article presents results from a meta-analysis of such studies completed between 2015 and 2019 and provided to us by HHS. Studies were…

High-risk sexual behaviors (HRSBs; e.g., having sex without protection against pregnancy or sexually transmitted infections) are a public health problem. HRSBs disproportionally impact college students and are associated with numerous negative outcomes, such as unwanted pregnancies. Alcohol use has been strongly linked to HRSBs in college…

Adopting an ethnographic lens, readers are provided a look inside a California high school sexuality education classroom. On this chosen day, two invited guest speakers from an outside company are teaching students about pregnancy prevention, healthy relationships, and risks associated with having sex. Analysis of the guest speakers' pedagogical…

Objective: Hookup apps, such as Tinder, have become vastly popular among college students, and hookup culture has become more normatively acceptable. The current study seeks to understand the associations of hookup app uses and outcome variables including sexual attitudes, relationship turbulences, and risky sexual behaviors. Participants and…

The Youth Risk Behavior Survey (YRBS) is an epidemiologic surveillance system that was established by the U.S. Centers for Disease Control and Prevention (CDC) to help monitor the prevalence of behaviors that not only influence youth health but also put youth at risk for the most significant health and social problems that can occur during…

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,…

This paper explores the use of withdrawal as a harm reduction approach to adolescent pregnancy prevention and its association with condom use. Data come from a baseline survey of a randomised controlled trial to test the effectiveness of FLASH, a sexual health education curriculum. Study participants completed electronic self-report surveys in…

The purpose of this study was to investigate the association between unrealistic optimism (UO) and risky sexual behavior (RSB) and related consequences in a college student sample. Participants believed they had significantly lower "personal" risk of engagement in alcohol-related sexual activity, unintended pregnancy, and STIs than the…

Objective: Numerous studies have examined the effectiveness of graphic health warnings on different population segments, including male and female smokers, in an effort to reduce health disparities in Europe and the USA. However, research exploring the impact of gender-specific tobacco control interventions on Asian smokers is lacking. This study…

School-based health clinics (SBHCs) offer convenient, free, and much-needed health services to adolescents who have been shown to lack access to preventative care and treatment. With high rates of risky sexual behavior and associated negative health outcomes, SBHCs are particularly effective in providing sexual health services. This article…

School nurses are often sources of health-care support for teens with sexually transmitted infections (STIs) and unintended pregnancies. However, providing prevention (e.g., condoms) and teaching technical skills (e.g., condom use) needed to reduce high-risk sexual behavior may require a change in perceptions and policies. This study used a…

Montana is proud to have completed over three decades of participation in the Youth Risk Behavior Survey (YRBS). These results are valuable to educators, school boards, and communities, including parents and students, in understanding the health risks of Montana students, enabling districts to design local health and physical education curriculum…
