Background: LGB people were reported to have higher levels of psychological distress than their heterosexual counterparts. Health risk behaviors were also found to have negative effects on HRQOL. However, few studies have examined whether the effects of health risk behaviors on HRQOL differ between LGB and heterosexual college students.

Methods: Data from 888 college students were collected via a self-administered anonymous survey, which included questions regarding health risk behaviors and WHOQOL-BREF, an abbreviated version of the World Health Organization QOL assessment (WHOQOL-100). Multivariate linear regression analysis was conducted to examine whether the effects of health risk behaviors on HRQOL were different between LGB and heterosexual college students, separated by gender.

Results: In general, HRQOL was significantly different in the social relationships domain among LGB and heterosexual men and women. For male college students (N=513), past-year heavy episodic drinking had a significant adverse effect on the psychological HRQOL in gay/bisexual (N=62; ß=-2.022, p=0.048) but not in heterosexual men, after controlling for age, class rank quintile, personal monthly income, and sexual debut before age 20. Adjusting for the same variables, for female college students (N=375), problem gambling and having unprotected sex in the past year had significant adverse effects on the environment HRQOL in lesbian/bisexual (N=67; ß=-1.831, p=0.021 and ß=-1.665, p=0.023, respectively) but not in heterosexual women.

Conclusions: Significantly different effects of health risk behaviors on HRQOL were found among LGB and heterosexual college students. Future research may focus on these behaviors and affected domains of HRQOL, and explore possible mechanisms.
