Modelling population-level and targeted interventions of weight loss on chronic disease prevention in the Canadian population.
Obesity is a known risk factor for major chronic diseases. Prevention of chronic disease is a top global priority. The study aimed to model scenarios of population-level and targeted weight loss interventions on 10-year projected risk of chronic disease in Canada using a population-level risk prediction algorithm. ⋯ The population-level intervention estimated a greater reduction in risk (0.2%), compared to the targeted interventions (0.1%). The combined approach estimated a 0.3% reduction in chronic disease risk. Our modelling predicted that population-level approaches that achieve weight loss in combination with targeted weight loss interventions can substantially decrease the chronic disease burden in Canada.

State expansion of supplemental nutrition assistance program eligibility and rates of interpersonal violence.
Food insecurity is associated with an increased likelihood of interpersonal violence. The Supplemental Nutrition Assistance Program (SNAP) is the largest program addressing food insecurity in the U.S. States can eliminate the asset test and/or increase the income limit for SNAP eligibility, expanding the number of households receiving assistance. We examined the association of state elimination of the asset test and increases in the income limit with rates of interpersonal violence, including intimate partner violence (IPV), other relationship violence (violence by a parent, friend, etc.), and stranger violence. ⋯ Expanding SNAP eligibility may help prevent interpersonal violence at the population-level.

The role of language in mammography orders among low-income Latinas over a 10-year period.
Latinas in the United States have higher mortality from breast cancer, but longitudinal studies of mammography ordering (a crucial initial step towards screening) in primary care are lacking. ⋯ These findings suggest that breast cancer detection barriers in low-income Latinas may not stem from a lack of orders in primary care, but in the subsequent accessibility of receiving ordered services.

Physical activity and recreational screen time change among adolescents in Canada: Examining the impact of COVID-19 in worsening inequity.
The purpose of this study was to assess if sub-populations of adolescents in Canada (i.e., race/ethnicity, sex/gender, and socioeconomic status [SES]) experienced a larger change in physical activity and screen time between the 2019-2020 (pre-pandemic) and the 2020-2021 (mid-pandemic) school years. Longitudinally linked data from pre-pandemic and mid-pandemic school years of a prospective cohort study of secondary school students in Canada (n = 8209) were used for these analyses. Multivariable regression modelling tested the main effects of race/ethnicity, sex/gender, and SES on changes in moderate-to-vigorous physical activity (MVPA) and screen time duration as well as adherence to Canada's 24-h Movement Guidelines. ⋯ MVPA in White participants decreased less than Asian participants (-10.7 [-19.5, -1.9] min/day) with a similar non-significant pattern observed in Black and Latin participants. Adolescents in higher SES categories fared better on adherence to MVPA (highest vs. lowest OR = 1.41 [0.97, 2.06]) and screen time recommendations(highest vs. lowest AOR = 3.13 [0.91, 11.11]). Results support the hypothesis that existing inequitable sociodemographic differences in MVPA participation and screen time have worsened throughout the pandemic.

The role of sleep duration in suicide risk among sexual and gender minority adolescents.
Short sleep duration is linked with suicide risk in adolescence. Sexual and gender minority (SGM) adolescents experience substantially increased risk for suicide compared to their non-SGM peers. ⋯ Sleep duration is a crucial and understudied mechanism underlying suicide risk disparities affecting SGM adolescents. Family-based interventions may improve SGM adolescent sleep and reduce suicide risk.
