LEAL F., Ingrid et al. Edad de inicio sexual y asociación a variables de salud sexual y violencia en la relación de pareja en adolescentes chilenos. Rev. chil. obstet. ginecol. [online]. 2018, vol.83, n.2, pp.149-160. ISSN 0048-766X.


To analyze the age of sexual debut, its association with variables of sexual health and intimate partner violence (PV) in Chilean adolescents.


Cross-sectional and analytical study. The sample was obtained from a database with national representation. Multiple logistic regression analysis was carried out controlling by age and socioeconomic group and stratifying by sex to determine association between the variables.


In women, the age of early sexual initiation increases in 0.85 times the risk of unplanned pregnancy (OR: 1.85, 95% CI: 1.08 – 3.15). In men, the age of early sexual debut increases by 2.33 times the risk of not using contraception in the first sexual relationship (OR: 3.33, 95% CI: 1.85 – 6.01) and 4.33 times of having 2 and more sexual partners during the last 12 months (OR: 5.33, 95% CI: 3.25 – 8.75).

The prevalence of PV was 10%, psychological violence was the most frequent in men and women. In women, the age of early sexual initiation increases 5.72 times the risk of physical violence (OR: 6.72, 95% CI: 2.52 17.87) and 7.82 times psychological violence (OR: 8.82; 95% CI: 4.10 – 19.0)

Adolescents who have an early onset of sexual activity show more evidence of control practices and abuse toward their partner, compared to men.


Intimate partner violence exists with a worrisome frequency, having an association with early sexual initiation, especially in women, increasing the risk to health in general. It is necessary to train health and education teams and implement comprehensive strategies that contribute to promoting the health and well-being of adolescents.
