The study was done with the purpose to examine the impact of household composition and satisfaction with family life on sexual behaviors among high school male and female students in Hong Kong.

3907 total students fulfilling the inclusion criteria were included in the analysis. 202 students were sexually active. 505 students had ever sexually harassed others and 303 students had ever been sexually harassed by others. 58 students had ever had nude chats. 1005 students had sexted in the last 12 months. Students who lived with both biological parents were less like to be sexually active, to sext, and to have nude chats than those who did not. Students who had higher family life satisfaction were less likely to be sexually active, to sexually harass others, to be sexually harassed by others, to sext, and to have nude chats than students who had lower satisfaction with their family life.

The study concluded that sexual health programs and interventions should consider family functioning. Students who have low family satisfaction and those who do not live with both their biological parents should be targeted for sexual health interventions.
