Adolescent sexual behaviour and academic performance of Italian students

摘要

This article estimates the effect of sexual activity during adolescence on academic performance of high school students in Italy. We exploit a sample of university students drawn from the two waves (2000 and 2017) of the SELFY survey. The survey collects information on sexual behaviours during adolescence and on the grade obtained at the high school final examination, as well as on a number of family-related variables. Overall, results suggest a negative relationship between sexual activity and the grade obtained in the high school final examination supporting the idea that health and education consequences of sexual activities among adolescents merit public policy efforts. To deal with the potential influence of unobserved characteristics at individual and family level, we also pursue an instrumental variables approach. As instruments, we use three questions as proxy of erotophobia-erotophilia personality trait. This extension of the analysis confirms the results of the baseline models.
