Introduction. One of the main health problems faced by adolescents is Risky Sexual Behavior. The aims of the study were: To compare the CSR among a group of adolescents with different levels of executive functioning and to analyze the factors related to these behaviors using a linear regression model. Method. The sample consisted of 50 adolescents, 25 men and 25 women. To measure the CSR was used, the Scale of Sexual Behaviors and the questionnaire of the National Survey of Health and Sexual Habits, for the evaluation of the executive functions, the subtests of the Orbito Medial index of the Battery of Executive Functions and Lobes Frontals. Results: An ANOVA was performed taking the CSR score as the dependent variable and the level obtained in the Medial Orbit index as the independent variable. Likewise, an ordinary least squares model was made. According to the results, no significant differences were found between the groups p = .525. However, those with lower scores on tasks that evaluated inhibitory control and benefit-risk processing obtained higher CSR scores. On the other hand, the CSR that is mainly related to a high-risk level is: the early age of beginning sexual relations (-.930). Conclusions. Emphasis is placed on the importance of studying the phenomenon and its relationship with cognitive processes. [ABSTRACT FROM AUTHOR]

Introduction: College students, a subpopulation of emerging adults, are particularly vulnerable to exhibit substance abuse and risky sexual behaviors. These behaviors put people at risk for sexually transmitted infections and/or unwanted pregnancy. Aim: To examine, in college students, whether the pattern of substance use (i.e., alcohol versus co-use of alcohol and marijuana) and the level of impulsivity are associated with the frequency of risky sexual behaviors with occasional partners. Method: A sample of 467 college students completed an online survey that assessed the frequency of risky sexual behaviors, past-year alcohol and marijuana use and trait-like impulsivity. Results: Alcohol/marijuana co-users, compared with alcohol users, reported a higher average of sexual partners per year and greater feelings of regret following careless sexual encounters. Co-users with medium or high levels in lack of perseverance and lack of premeditation (i.e., two facets of impulsivity) reported higher frequency of sexual encounters than alcohol users and/or students with low impulsivity. Conclusions: Findings suggest substance co-use, alongside different facets of impulsivity, are associated with greater frequency of specific risky sexual behaviors. These findings could better inform interventions aimed at prevent risky sexual behaviors in Argentinean college students. [ABSTRACT FROM AUTHOR]

Objective: To identify what variables influence having multiple sexual partners. Methods: A cross-sectional study was carried out with 542 women of two higher education institutions from the northwest of Mexico, who answered a questionnaire measuring psychological variables underlying high-risk sexual behaviors. The data were analyzed with T-tests, Mann-Whitney U tests, and with a multiple linear regression. Results: A multiple linear regression analysis showed the following results: for women from Hermosillo, Sonora, the predictors of high-risk sexual behaviors were biological age, age of sexual debut, and one biological state «I was physically excited», with those variables explaining 53.4% of the total variance; for women from Ciudad Juarez, Chihuahua, the predictors were biological age, and two types of biological states «I was physically excited» and «I was under the influence of alcohol», explaining 20.8% of the total variance. Conclusions: The results underscore the need to design prevention programs directed to avoid HIV infection based on behavioral competencies training. [ABSTRACT FROM AUTHOR]

The development of treatment of HIV/AIDS infection and its administration imply a great cost to public and private health systems, therefore, it is very important to insist on prevention as a measure of control of the problem. In this aspect of prevention, sexual behavior has an important role and may be divided into a planned and controlled sexual conduct (condom use, monogamy) and an impulsive and irresponsible one (non-safe sex). In order to avoid risky sexual behavior, it is important how able (self-efficacy) a person is to control and plan his/her sexual conduct. Objective: To show some differences between men and women, in teenagers from health centers, about self-efficacy in sexual behavior to prevent AIDS; the attitude towards the condom's use, planning of sexual relations and monogamy, satisfaction with information about sex and its main source, as well other variables of sexual conducts. Material and methods: A self-administered questionnaire was used, it was integrated by Self-Efficacy Scale for AIDS by Kasen, Vaughan and Walter (1992) with a scale of 22 questions. This scale has been adapted to Spanish and has been studied first by Ochoa, Sayés and Villamarinin 1995 and then by López Rosales, et al, 1999, modified to 27 elements (SEA-27) by Lopez Rosales and Moral de la Rubia; more 23 questions about important aspect of sexual behavior related to HIV transmission. This study was co-relational with a non-experimental design of transversal type. It was performed in a non-probabilistic sample of incidental type of 962 teenagers from 58 public health centers in Monterrey. Results: in women the age of sexual relations' beginning is 15 years and in men, 13 years, 74% of both groups say that their first relation was at home: 76% do not use condom; before 18 years old men have, or average, three sexual partners and women, two. Conclusions: In programs of AIDS prevention, women should develop a higher assertively to request the condom use. Men should develop a higher consciousness of the danger of the disease transmission when they commit risky behaviors, as well as reflect on the attitude of "taking advantage of" any opportunity of sexual contact without caring whether it is of high risk or not.
