Sexual behaviour in a low-income high school setting in Stockholm.

Teenage abortions and sexually transmitted infections (STIs) are increasing in Sweden, and risky adolescent sexual behaviour is an issue of major concern. The aim of the present cross-sectional questionnaire-based study was to investigate adolescent sexual experience in a low-income high school setting in Stockholm. Among 340 students, 258 participated, response rate=75.9%, mean age=17 years. Homo- or bisexual preference was reported by 11.6% (29/250). Experience of oral sex was reported by 66.3% (163/246), vaginal intercourse by 55.5% (141/254), and anal sex by 10.0% (25/250), with no gender-specific differences. Five or more coital partners were reported by 29.8% (34/114). Condom use at first and most recent intercourse was reported by 61.7% (87/141) and 42.6% (60/141), respectively, and condom breakage by 39.5% (34/86). Truancy, smoking, alcohol and drug use were factors associated with coital experience. Sexual abuse was reported by 2.2% (3/134) of the boys and 13.0% (16/123) of the girls.
