Abstract
Objective
Identify the prevalence of sexual activity initiation in adolescents and the practice of safe sex among them.
Method
A cross-sectional study carried out with 499 adolescents in Porto Alegre, Minas Gerais, from February to April 2017, using a self-administered and semi-structured questionnaire, covering sexual initiation and practices, knowledge about contraceptive methods, prevention of sexually transmitted infections and participation in educational activities on the theme. The data were analyzed using descriptive statistics and the statistical differences were assessed using Pearson's X2 test.
Results
The prevalence of sexual activity was 47.3%, with a mean age of 14.1 years old at first sexual intercourse, and a tendency for early sexual initiation in the male gender. One third of the first sexual intercourses were unprotected (33.9%). Female participants had greater knowledge about contraceptive methods and disease prevention, lower adherence to condom use and greater use of oral and emergency contraceptives.
Conclusion and implications for the practice
The study showed an early initiation of sexual life among adolescents, and one third of unprotected sexual intercourses. There is a need for health and education actions that guarantee the acquisition of knowledge and access to contraceptive methods.
