Trends in suicidality among sexual minority and heterosexual students in a Canadian population-based cohort study.

OBJECTIVES: Despite evidence from numerous studies that document disparities in suicidality for sexual minorities, few have investigated whether or not these trends have improved over time, which is the objective of the current study. METHODS: Using school-based population data over a 15-year period (1998 to 2013), multivariate logistic regressions were used to calculate age-adjusted odds ratios separately by gender. Interactions were included to test widening or narrowing disparities within orientation groups, which makes this one of the first studies to test whether gaps in disparities between heterosexual and sexual minorities have widened or narrowed over time. RESULTS: Results show that sexual minority youth are persistently at a greater risk for suicidal behaviour, a trend that has continued particularly for bisexual youth of both sexes. Results also suggest that the gap in suicidal behaviour is widening among some female sexual orientation groups, yet narrowing for other male sexual orientation groups. CONCLUSIONS: These findings have important public health implications, especially since we see decreases in suicidal behaviour for heterosexual adolescents, but not in the same way for many sexual minority youth, despite advances in social acceptance of gay, lesbian, and bisexual issues in North America.

Pride and prejudice: factors affecting school attachment among lesbian, bisexual, and heterosexual girls.

School attachment is often regarded as a key measure in gauging the integration and wellbeing of students. Previous research suggests that levels of school attachment are generally lower among sexual minority students, but most studies focus on between-gender comparisons and do not conduct within-gender analyses. Using data from the First National Climate Survey on Homophobia and Transphobia in Canadian schools, this study set out to empirically analyze what, if any, differences exist among lesbian, bisexual, and heterosexual female students when assessing the relationship between homophobic and gender-negative language, feelings of safety, harassment/direct victimization, and school climate on school attachment. Bivariate and multivariate findings suggest that there are key differences among female students in terms of school attachment.
