Exploring muscularity concerns and behaviours among boys and men with probable eating disorders.

The muscular body ideal and muscularity concerns and behaviors have been posited to be major drivers of eating disorder psychopathology among boys and men. However, there is limited evidence of this, particularly among large, international samples. This study aimed to compare muscularity concerns and behaviors across probable eating disorder diagnoses among a non-clinical sample of boys and men from Canada and the United States.

Family incarceration and barriers to mental health care among low-income US veterans.

Background: Family member incarceration is a risk factor for mental health challenges. However, less research has investigated the relationship between family member incarceration and barriers to mental health services.

Methods: Data were drawn from the 2023 National Veteran Homeless and Other Poverty Experiences (NV-HOPE) Survey, a nationally representative sample of US veterans living at or below 300 % of the federal poverty level (N = 978).

Police Contact and Mental Health Among Adolescents With Autism: Findings From the UK Millennium Cohort Study.

Purpose: The present study examines differences in police contact and mental health outcomes between autistic and nonautistic youth in the United Kingdom.

Methods: Data from the UK Millennium Cohort Study-a nationally representative cohort study that follows youth born between September 2000 and January 2002-were analyzed in 2024 (n = 11,859).

Objectives: This study examined the relationship between early-life violent victimisation and dental care utilisation patterns from adolescence to middle adulthood (ages 11-43).

Methods: Data were from Waves I through V of the National Longitudinal Study of Adolescent to Adult Health (Add Health). Group-based trajectory modelling (GBTM) was used to examine patterns of dental care use across five waves, spanning ages 11-43.

Family social support during incarceration: implications for health upon release.

Incarceration is associated with adverse physical and mental health that are often brought to light during reentry into the community, particularly in the immediate period following release. Social support, specifically from family members, has been identified as a key protective factor that may promote health and reintegration success among formerly incarcerated individuals. However, less is known about how specific types of family support-emotional and instrumental-relate to health outcomes following release from incarceration.

Prior incarceration and food insecurity trajectories through older adulthood: findings from the Health and Retirement Study.

Introduction: Prior cross-sectional research has identified incarceration as a risk factor for food insecurity across the life course. However, there is a lack of longitudinal studies on the relationship between prior incarceration and food insecurity over time.

Methods: This study uses biennial data across 10 time points from the Health and Retirement Study (years 2012-2022) to examine the association between prior incarceration and longitudinal trajectories of food insecurity among adults aged 55 and older in the USA (N=8229).

Police Avoidance and Depressive Symptoms Among Black Youth.

Objective: Police violence is a public health crisis that disproportionately impacts Black youth, worsens their mental health, and potentially heightens their efforts to circumvent police surveillance (ie, police avoidance). Even so, the link between Black youths' police avoidance and depressive symptoms has yet to be empirically examined. The present study examined this association, adjusting for police violence stress and diverse police exposures.

Protocol for the Houston Hospital-Based Violence Intervention Program.

Firearm violence is a leading cause of injury and mortality in the United States. Hospital-based violence intervention programs (HVIPs) are a promising public health strategy designed to reduce recurrent violence by engaging patients during hospitalization and connecting them to support services after discharge. This protocol describes the design and implementation of the Houston Hospital-Based Violence Intervention Program (Houston-HVIP), which will be evaluated by a randomized controlled trial conducted at a Level 1 trauma center in Houston, Texas.

Prescription weight loss medication use and eating disorder psychopathology among adolescent boys and young men from Canada and the United States.

This study aimed to identify the prevalence of prescription weight loss medication use among boys and men, describe the sociodemographic differences between those who did and did not report use, and explore differences in eating disorder attitudes and behaviors between those who did and did not report use. Data from 1543 boys and men from Canada and the United States aged 15 to 35 were analyzed. The prevalence of prescription weight loss medication use in the past 12 months was estimated.

Cyberbullying, mental health, and substance use experimentation among early adolescents: a prospective cohort study.

Background: Although cyberbullying has been linked with adverse health outcomes, most prior studies have been cross-sectional, and there are limited large-scale, prospective analyses examining cyberbullying and mental health and substance use outcomes in early adolescents. Therefore, the aim of this study was to determine prospective associations between cyberbullying, mental health, and substance use experimentation one year later in a US national cohort of early adolescents (11-12 years old).

Methods: We analyzed prospective cohort data from the Adolescent Brain Cognitive Development (ABCD) Study (Year 2, N = 9799).

Social epidemiology of bedtime screen use behaviors and sleep outcomes in early adolescence.

Objectives: The current study aimed to determine sociodemographic associations of bedtime screen use behaviors and the sociodemographic differences in the associations between bedtime screen use and sleep outcomes in a national (US) study of early adolescents.

Methods: We analyzed cross-sectional data from 10,305 early adolescents (12-13years, 48.4% female) in the Adolescent Brain Cognitive Development (ABCD) Study (Year 3, 2019-2021).

Expanding Access to Quality Reproductive Health Care After the Dobbs v. Jackson Women's Health Organization Decision.

Recent studies have shown an increase in the rates of sterilization procedures among women of childbearing age after the Dobbs v. Jackson Women's Health Organization decision in June 2022. This trend may extend to the use of other forms of birth control, such as oral contraceptive pills and long-acting reversible contraception.

Social Media Use and Depressive Symptoms During Early Adolescence.

Importance: In 2023, the US Surgeon General issued the Advisory on Social Media and Youth Mental Health, identifying critical research gaps that preclude evidence-based guidance given that most studies of social media and mental health have been cross-sectional rather than longitudinal and have focused on young adults or older adolescents rather than on younger adolescents.

Objective: To evaluate longitudinal associations between social media use (time spent on social media) and depressive symptoms across 4 annual waves spanning a 3-year follow-up period from late childhood to early adolescence.

Design, Setting, And Participants: In this prospective cohort study using data from the Adolescent Brain Cognitive Development Study across 21 study sites from October 2016 to October 2018, children aged 9 to 10 years at baseline were assessed across 4 waves (baseline, year 1, year 2, and year 3), with year-3 follow-up through 2022.

Associations between muscularity-oriented social media content and muscle dysmorphia among boys and men.

This study aimed to determine whether viewing muscularity-oriented social media content was associated with muscle dysmorphia among a sample of boys and men from Canada and the United States. Data from the Study of Boys and Men (2024; N = 1553) were analyzed. Multiple linear regression analyses were conducted to determine the associations between viewing content with 1) muscular bodies, 2) muscle-building dietary supplements (e.

Social epidemiology of sports and extracurricular activities in early adolescents.

Background: This study examines the social epidemiology of sports and extracurricular activities in early adolescents (9-14 years) using a diverse national U.S.

Methods: We examined data from baseline (2016-2018, ages 9-10) to Year 3 follow-up (2019-2021) of the Adolescent Brain and Cognitive Development (ABCD) Study (N = 11,270).

Violent victimization trajectories over the life course and past year dental care use in adulthood in the United States.

Objectives: Exposure to violence has been linked to poorer health outcomes and reduced healthcare utilization. Yet research has not assessed how patterns of violent victimization over the life course are associated with dental care use. This study aims to fill this gap by examining the relationship between violent victimization trajectories from adolescence to adulthood and dental care use in adulthood.

Eating disorders among an online sample of Canadian and American boys and men.

There is a continued need to identify the prevalence and sociodemographic correlates of eating disorders, particularly among the under-researched group of boys and men, to inform prevention and intervention efforts. Data from The Study of Boys and Men, a sample of 1553 boys and men aged between 15 and 35 years in Canada and the United States, were analyzed in 2024. Probable eating disorder diagnoses were identified using a previously established algorithm based on current diagnostic criteria.

Linkages between incarceration and health for older adults.

The aging population in United States (US) correctional facilities has grown dramatically over the last several decades. At present, roughly one in four adults incarcerated in US prisons are at least 50 years of age. Research over the last ten years has likewise expanded to catalog the impacts of incarceration on older adults, and the myriad ways incarceration is unique for this population.

Firearm Violence and Dental Health: A Neighborhood Analysis in 100 U.S. Cities, 2014-2022.

Introduction: This study examined the relationship between community-level firearm violence and dental health, focusing on dental care utilization and edentulism (i.e., total tooth loss) .

Dental care trajectories among formerly incarcerated older adults in the United States.

A growing body of research has documented an association between prior incarceration and lower dental care use, yet the longitudinal impact of prior incarceration on dental care patterns over time among older adults remains unexplored. This study aims to investigate whether prior incarceration is associated with differing trajectories of dental care use among older adults in the United States. Data were drawn from the 2012-2020 waves of the Health and Retirement Study (HRS), a nationally representative longitudinal survey of older adults in the United States (n =  5,893).

When youth record police: Investigating officer intrusion and mental health repercussions among Black youth in Baltimore City, Maryland.

Rationale: Recording the police is a high-stakes racial justice issue for minoritized youth and communities. No studies to date have explored youths' efforts to record police and the mental health impacts of these experiences for youth.

Objective: This study examined the features and mental health repercussions of in-person stops where youth attempted to record police.

Social epidemiology of cardiometabolic risk factors in early adolescents.

Background: To estimate associations between sociodemographic factors and cardiometabolic risk factors among a demographically diverse sample of U.S. adolescents aged 10-14 years.

Historical redlining and criminal offending trajectories from adolescence to adulthood.

Purpose: Area-level research finds higher contemporary crime rates in historically redlined communities. However, there is a lack of multilevel research assessing the relationship between living in a historically redlined area, individual patterns of criminal offending over time, and whether this relationship varies for different racial-ethnic groups.

Methods: Data are from Waves I, III, IV, and V of the National Longitudinal Study of Adolescent to Adult Health (n = 7843; ages 11-44), including recently digitized 1930s redlining maps from the Home Owners' Loan Corporation.
