Do Adolescent Sexual Behavior and Intention to Engage in Sexual Behavior Change in High School Years in Hong Kong?

We also focused on the related sociodemographic and family correlates. Design, Setting, Participants, Interventions, and Main Outcome Measures: A 6-year longitudinal study was conducted. At each wave, a questionnaire was used to collect data on sociodemographic characteristics, positive youth development, and family functioning in the respondents. Results: Individual growth curve models showed that adolescent sexual behavior and intention increased over time. Adolescents with higher levels of positive youth development reported lower levels of past sexual behavior. Youths from better-off and higher functioning families increased their sexual behavior at slower rates than did youths from families with economic disadvantage and poor family functioning. Regarding intention to have sex, older adolescents reported higher levels of intention. Youngsters with higher levels of perceived family functioning and positive youth development reported lower levels of initial intention. Adolescent boys increased their intention at a faster rate than did girls. Conclusion: Findings from the study identified risk factors (ie, age, gender, and economic disadvantage) and protective factors (ie, healthy family functioning, positive youth development) that influence the levels and growth rates of adolescent sexual behavior and intention. Implications for future research and interventions are discussed.
