摘要：The purpose of the present study was to examine differences in lifestyle factors such as physical activity among homosexual (gay or lesbian), bisexual, and heterosexual Korean adolescents.The sample consisted of 74,186 adolescents from grades 7-12 (ages 12-18) who participated in the 8(th) annual Korea Youth Risk Behavior Web-based Survey in 2012. Of this sample, only 11,829 provided enough information regarding their romantic and sexual experiences to define them as gay, lesbian, bisexual, or heterosexual. From this information, males were divided into gay (n = 323), bisexual (n = 243), and heterosexual (n = 6,501) groups, and females were divided into lesbian (n = 208), bisexual (n = 113), and heterosexual (n = 4,441) groups. Differences in lifestyle factors according to sexual orientation were analyzed using one-way analysis of variance.Males showed significant differences by sexual orientation group in terms of frequency of smoking (P = 0.029), alcohol consumption (P < 0.001), muscular strength exercises (P = 0.020), and walking for at least 10 minutes per week (P < 0.001). Females showed significant differences by sexual orientation group in terms of frequency of smoking (P < 0.001), alcohol consumption (P < 0.001), vigorous physical exercise (P < 0.001), moderate physical exercise (P < 0.001), and muscular strength exercises (P < 0.001), as well as for self-reported mental stress (P < 0.001).We concluded those gay and bisexual males and lesbian and bisexual females had significant lifestyle differences as compared with heterosexual adolescents. This effect was stronger for females than for males.
