Sexual media use by young adults in Hong Kong: prevalence and associated factors.

The prevalence of sexual media use, and factors associated with it, among Chinese young adults were studied in Hong Kong. Questions on use of sexual media were asked as part of a youth sexuality study conducted by the Family Planning Association in 1996. In a population-based cross-sectional study, 517 men and 447 women aged 18-27 years completed an anonymous structured self-administered questionnaire. The overall prevalence [95% confidence interval (CI)] of ever purchased or rented any type of sexual media was 57.8% (54.7-60.9). More men (70.2%; 95% CI: 66.3-74.2) than women (43.4%; 95% CI: 38.8-48.0) used sexual media. Of 31 independent variables tested by stepwise logistic regression, seven variables significantly predicted sexual media use: age (adjusted odds ratio OR = 1.5 for 21-24 and 1.8 for 25-28, versus 20 or below), male gender (OR = 3.0), number of sexual partner (OR = 2.2 for one and 2.8 for two or more partners), masturbation in the past week (OR = 3.2), being out of school (OR = 1.5), quarrel with family member in past 6 months (OR = 1.8), and religion (OR = 1.6 for no religion and 3.4 for traditional Chinese religion, versus Christians) (all adjusted OR:p < 0.05).
