Exploring gender differences in the longitudinal association between bullying and risk behaviours with Body Mass Index among COMPASS youth in Canada.
The purpose of this study was to identify gender differences in the association between bullying and Body Mass Index (BMI) longitudinally. Longitudinal data (2013-2015) from 4510 youth (Ontario, Canada) were used to model BMI with consecutive bullying status prospectively, adjusting for previously identified gender-specific health risk behaviour latent classes. To assess for gender differences, these mixed-effects models were stratified by gender. ⋯ I. = 1.11, 2.29)] at follow-up. In contrast with previous literature that measured BMI during adulthood (i.e., years after school victimization), our study adds a unique contribution to the literature that across one year (while youth are still in secondary school), bullying is associated with higher odds of weight status and BMI among female and male youth. Since this increase occurs during secondary school, school-based programs aimed at decreasing youth bullying behaviours and addressing increases in BMI before youth leave school are of paramount importance.

Harmful masculinities among younger men in three countries: Psychometric study of the Man Box Scale.
In response to growing evidence of associations between harmful masculinities and adverse health outcomes, researchers developed the Man Box Scale to provide a standardized measure to assess these inequitable gender attitudes. In 2019, we evaluated the psychometric properties of the 17-item Man Box Scale and derived a 5-item short form. Using previously collected data (in 2016) from men aged 18-30 years across the United States (n = 1328), the United Kingdom (n = 1225), and Mexico (n = 1120), we conducted exploratory (EFA) and confirmatory factor analyses (CFA), assessed convergent validity by examining associations of the standardized mean Man Box Scale score with violence perpetration, depression, and suicidal ideation, and assessed internal consistency reliability of the full scale. ⋯ IRT resulted in a 5-item short form with good fit through CFA and convergent validity, and good internal consistency. The Man Box Scale assesses harmful masculinities and demonstrates strong validity and reliability across three diverse countries. This scale, either short or long forms, can be used in future prevention research, clinical assessment and decision-making, and intervention evaluations.

Physical activity trajectories from childhood to late adolescence and their implications for health in young adulthood.
Physical activity has been associated with physical and mental health across the life course, yet few studies have used group-based trajectory modeling to examine the effect of longitudinal patterns of physical activity during childhood and adolescence on adult health outcomes. The Raine Study data from Gen2 follow-ups at 8, 10, 14, 17, 20, and 22 years collected between 1998 and 2014 were used. Latent class analysis identified trajectories using parent-reported physical activity for ages 8 to 17. ⋯ Physical activity trajectories showed different associations between sexes for self-reported physical and mental health, BMI, systolic blood pressure, and depression symptoms. Being in the high- or mid-activity trajectory was associated with a more favorable cardiometabolic and mental health profile in young adulthood. Strategies are needed to help less active children to increase physical activity throughout childhood and adolescence to improve young adult health outcomes.

Obesity-related multimorbidity and risk of cardiovascular disease in the middle-aged population in the United States.
To investigate the prevalence of obesity-related multimorbidity (co-occurrence of ≥2 obesity-related chronic diseases, ORCDs) and the risk of cardiovascular disease in the presence of multimorbidity in middle-aged adults in the United States. National Health and Nutrition Examination Survey data from 2007 to 2016 were used. Target ORCDs included hypertension (H), diabetes (D), coronary heart disease (C), and stroke (S). ⋯ Compared with no hypertension/diabetes/coronary heart disease, pre-existing hypertension in combination with diabetes/coronary heart disease significantly increased risk of stroke [C + D + H (aHR 32.6, 95% CI 12.2-87.1), C + H (aHR 25.4, 95% CI 12.1-53.6), D + H (aHR 5.3, 95% CI 2.6-10.8)]. Obesity-related multimorbidity is prevalent and highly associated with cardiovascular disease development. To reduce the detrimental health impact of multimorbidity, intervention strategies should target preventing increasing multimorbidity and detecting/managing diabetes and hypertension prior to the onset of cardiovascular disease.

History of child maltreatment and excessive dietary and screen time behaviors in young adults: Results from a nationally representative study.
Child maltreatment is common and has been associated with substance use addictions, yet few studies have examined associations with potentially addictive dietary and screen time behaviors. The goal of this study was to assess associations between retrospectively self-reported child maltreatment (sexual abuse, physical abuse, emotional abuse, and neglect) and excessive self-reported dietary (sugar sweetened beverage and fast food consumption) and screen time behaviors (television/video watching and leisure time computer use) in early adulthood, overall and by sex and race/ethnicity. Associations were examined using data from 10,813 participants 24-32 years old from the National Longitudinal Study of Adolescent to Adult Health. ⋯ Some associations were particularly strong in racial/ethnic minorities, especially Latina females (poly-maltreatment-sugar sweetened beverage association: aPR = 6.14, 95% CI:2.12, 17.75; poly-maltreatment-computer use association: aPR = 3.08, 95% CI:1.44, 6.58). These findings show that child maltreatment is associated with excessive dietary and screen time behaviors into adulthood, and these associations are present in racial/ethnic groups at high risk of cardiometabolic disease. Extension of an addiction paradigm to include dietary and screen time behaviors may inform health risks and disease prevention efforts in child maltreatment survivors.
