- Importance attributed by adolescents to sexual education: correlation with their attitudes, knowledge, and sexual behaviorPublication . Gonçalves, Raquel dos Santos; Alves, Carolina dos Santos Folques; Luz, Alexandra Maria Branco da; Ramalho, Sónia; Gordo, Clementina Maria Gomes de Oliveira; Barros, Teresa Madalena Kraus Brincheiro Hüttel; Dixe, Maria dos Anjos Coelho Rodrigues; Moleiro, PascoalIntroduction: Sexual education plays an important role in the prevention of risk-taking sexual behaviors. The objective of this study was to evaluate the importance attributed to sexual education by adolescents, correlating it with the assessment they make of their attitudes and with their knowledge towards sexuality. Methods: This observational study included adolescents who attended elementary or high school in the central region of Portugal. A characterization of sociodemographic and sexual data was made and the Adolescent Students’ Attitudes Scale towards Sexuality (E3AS) was applied. Results: We included 394 adolescents with a mean age of 14.9 ± 1.4 years. The majority (89.3%) attributed importance to sexual education. Adolescents that gave more importance to sexual education were the ones that ranked higher the information they learned about sexuality (r = 0.236), had less unprotected sex due to lack of information (r = -0.363) or because they were under the effect of alcohol and/or drugs (r = -0.365) and had a superior classification in F2 (r = 0.380), F5 (r = 0.402) and in the total scale (r = 0.531). Discussion and conclusion: Adolescents that attributed greater importance to sexual education were the ones that ranked higher the information they possessed about sexuality. After initiating sexual activity, a greater importance attributed to sexual education seems to have a protective effect on risk-taking sexual behaviors.
- Sexual behaviors: study in the youthPublication . Miranda, Patrícia Sofia Ferreira; Aquino, Joana Margarida Gonçalves; Monteiro, Ricardo Miguel Patrício de Carvalho; Dixe, Maria dos Anjos; Luz, Alexandra Maria Branco da; Moleiro, PascoalObjective: To characterize sexual behaviors in a sample of adolescents and youth. Methods: An analytical descriptive study using a questionnaire about sexual behaviors, adapted from the World Health Organization. It was distributed to students from a Portuguese city aged 14-24 years, during two months. Two age groups were defined: G1 – students aged 14-19 years; G2 – aged 20-24 years. Results: The sample included 2,369 students, 61% females and 70% in G1. The mean age of first sexual intercourse was 16.4±1.8 years; 93% used some contraceptive method in the first sexual intercourse. Out of those who did not use contraception in the first sexual intercourse, 83% were in G1 (p<0.001). Emergency contraception was used at least once by 54% (63% in G2, p<0.001). Among those who had unprotected sexual intercourses, 9% were under the influence of alcohol, 53.6% were female and 53.4% were in G2 (p<0.001). Homosexual contacts occurred in 21% of cases; in that, 62% in G1 and 84% among females (p<0.001). Conclusion: The use of contraceptionin the first sexual intercourse was common in our sample. However, the number of adolescents not using any contraceptive method in subsequent sexual intercourses, and the high percentage of them who consider it unnecessary, are a concern. Unprotected sexual intercourses, as well as unplanned intercourses and under influence of alcohol or drugs, especially in the youngest, urge the need for intervention regarding sexual education.
