Resumo
Adolescents and young people engage in risky sexual behavior, resulting in increased number of
sexually transmitted infections, and maintaining high rates of pregnancy. PURPOSE. To evaluate
the differences in sociodemographic and behavioral characteristics among sexually active and
virgin participants; to estimate the prevalence and to identify factors associated with sexual
iniciation up to age 15, and inconsistent condom use, and identify the reasons for not using condom
among adolescents and young adults. METHODS. A community-based, cross-sectional study
involving 1072 adolescents and young women, aged 15 to 24 years, living in three medium-sized
cities in the state of Goiás, between 2007 and 2009. All of them answered a questionnaire
containing sociodemographic and behavioral data. In order to evaluate the factors associated with
sexual iniciation up to age 15, and inconsistent condom use, a logistic regression analysis was
performed, with odds ratio (OR) and adjusted OR, with 95% confidence interval and level of
statistical significance of 5% (p <0.05). All of them signed the free and informed consent form. For
minors under 18 years old the exemption of the parents' signature was obtained by court order. The
project was approved by the Ethics and Research Committee. RESULTS. Of 1072, 64.9% were
sexually active. Sexually active women were 6.3 (95% CI: 3.98-9.96) times more probability of
being older than 19 years old, and 2.04 (95% CI: 1.19-3.49) times more probability of having
schooling less than eight years. The prevalence of sexual iniciation up to age 15 was 46.4% (95%
CI: 42.7-50.1) and inconsistent condom use was 73.2% (95% CI: 63.9% 82.6). The factors
associated with sexual iniciation up to age 15 were age less than 19 years old, had no religion and
had schooling less than eight years, with a OR of 3.13 (2.22-4.40), 2.05 (1.17-3.58) and 6.21 (4.14-
9.32) respectively. The only factor associated with inconsistent condom use was marital status or
stable union, with OR 4.63 (2.86-7.50). The most frequently cited reasons for non-use of condom
were "partner trust" by 49.8% and "partner dislikes" by 43.7%. CONCLUSION. The prevalence
of sexual initiation up to age 15, and inconsistent condom use were high. The factors associated
with these behaviors were different. Age less than 19 years old were associated with sexualiniciation up to 15, indicating a likely reduction in the age of sexual iniciation in adolescence. The
most frequent reasons for not using condoms were related to the sexual partner, which indicates
that gender factors need to be addressed in sex education strategies.
