Abstract: The onset for sexual activity in Grenada is low. Approximately 74% of males have their first sexual encounter by the age of 12 and 55% of females by the age of 13 years. Outside of the health education course in school, the topic of reproductive health is not commonly addressed; putting adolescents at increased risk for teen pregnancies and transmission of sexually transmitted infections. A protective factor for the delay of sexual initiation is parental involvement. Using proxy measures of checking homework, knowing where the child is and understanding the child were used to examine the association of parental involvement and age of sexual initiation. The results provide evidence that parental involvement and the father-daughter relationship do delay sexual initiation for adolescent females. What is less understood are the factors that are associated with adolescent males’ age of sexual initiation.
