Sexual behavior among high school students in Brazil: alcohol consumption and legal and illegal drug use associated with unprotected sex

The Association of Substance Use Before Sex and Condomless Sex: The Moderating Effects of Sexual Risk Behaviors, Perceived Sex Approval, and HIV/STI Risk Perception Among Youth

Youth are disproportionately affected by substance use and associated sexual risk behaviors, increasing STI and HIV susceptibility. This study analyzed the interplay between alcohol/drug use before sex (ABS/DBS), perceived sex approval (e.g., perceived familial or peer approval in engaging in sex), and HIV/STI risk perception among youth aged 13-21 (n = 150). We assessed how these factors influenced condomless vaginal/anal sex (VAS) and oral sex practices. Results showed significant interactions between perceived sex approval and lifetime ABS for lifetime condomless VAS, and between HIV/STI risk perception and lifetime ABS for current condomless oral sex. These findings underline the influence of perceived sex approval and HIV/STI risk perception on youth's sexual behaviors. Implications for targeted interventions are discussed.

Examining the mediating effect of real and cyber self-control on cyberbullying and health risk behaviors among secondary vocational students in China: a cross-sectional study

BACKGROUND

Cyberbullying and health risk behaviors are pervasive issues for secondary vocational students that not only detrimentally impact their academic achievement but also pose a significant threat to overall health. The purpose of this study was to understand the current situation of cyberbullying and health risk behaviors among secondary vocational students in China and to explore the relationships among cyberbullying, self-control, self-control over internet usage, and health risk behaviors through a mediation model.

METHODS

This was a cross-sectional study. From March to April 2023, a self-administered questionnaire was completed by a cluster sample of 1184 students from grades 1 to 3 at three secondary vocational schools in Jilin Province. The researchers utilized a sociodemographic questionnaire, the Cyberbullying and Cybervictimization Scale (CAV), the Adolescent Health Related Risky Behavior Inventory (AHRBI), the Self-Control Scale (SCS), and the Internet Usage Self-Control Scale (IUSCS-CS) to assess the prevalence and impact of cyberbullying and health risk behaviors. Descriptive statistics, spearman correlation analyses. Finally, the Process plug-in V2.16.3 was used to analyze a mediation model for the data.

RESULTS

Among secondary vocational students, 839 individuals (70.86%) experienced cyberbullying and 1036 individuals (87.50%) had one or more health risk behaviors. A chi-square test showed that the differences in cyberbullying incidence were statistically significant (P < 0.05) for being children, type of accommodation, residence, ethnicity, purpose of using the internet, and family composition. Statistically significant differences in health risk behaviors were observed based on gender, type of accommodation, residence, ethnicity, academic achievement, classmate relationships, purpose of using the internet, and family composition (P < 0.05). Health risk behaviors and cyberbullying were correlated (r = 0.60), health risk behaviors and self-control and internet usage self-control were negatively correlated (r = -0.42, -0.50). Mediation analysis indicated that self-control (0.02, 0.08) and internet usage self-control (0.08, 0.17) partially mediated the association between cyberbullying and health risk behaviors.

CONCLUSIONS

Secondary vocational students exhibit a high prevalence of cyberbullying and health risk behaviors. The study confirmed that self-control and internet usage self-control has an important role in mediating cybeibullying and health risk behaviors. Adolescent health promoters should develop targeted strategies to enhance the self-control of secondary vocational school students to mitigate their engagement in health risk behaviors.

Behind Prep Decisions: Understanding User Patterns and Discontinuation Factors in Real-World

This study aimed to characterize the epidemiological aspects of PrEP use and barriers to accessing this prophylaxis. This cross-sectional study was conducted between January 2021 and April 2022, encompassing 140 PrEP users treated at the Testing and Counseling Center (CTA) in Campo Grande, Mato Grosso do Sul. Data on sociodemographic characteristics and factors associated with PrEP discontinuation were obtained using a standardized questionnaire. Most PrEP users were cisgender men (92.00%), predominantly white (51.00%), over 30 years of age (56.50%), homosexual-oriented (76.50%), and had a minimum of 12 years of education (77.50%). Approximately 60.00% admitted to inconsistent condom use in recent sexual encounters, primarily involving anal intercourse. Approximately 88.00% perceived themselves as at risk of contracting STIs in the upcoming year. Regarding new presentation forms, 54.00% indicated a willingness to use "on-demand PrEP," and 92.00% expressed interest in using "injectable PrEP." After 6 months of follow-up, 43.60% (95.00% CI: 35.50-52.00) discontinued PrEP use, primarily due to changes in sexual behavior (38.30%) and difficulties accessing healthcare services (21.28%). This study underscores the need to involve diverse key populations and highlights the significance of PrEP as an ongoing monitoring strategy for HIV/STI prevention in addition to the importance of incorporating new formulations such as daily oral PrEP into the Brazilian National Health System (SUS).

Risky sexual behavior and associated factors among out-of-school youths in Addis Ababa, Ethiopia; mixed methods study

INTRODUCTION

Sexual risky behaviors, as defined by the World Health Organization, encompass a spectrum of sexual activities that heighten the likelihood of negative outcomes related to sexual and reproductive health. Despite the implementation of various healthcare programs and interventions, youths continue to encounter challenges in accessing reproductive health services. Consequently, they remain vulnerable to engaging in high-risk sexual behaviors; 50.36% of adolescents in Ethiopia. Therefore, this study was aimed to determine the prevalence of risky sexual behavior and associated factors among out-of-school Youths in Addis Ababa, Ethiopia; 2023.

METHODS

A community based cross sectional mixed methods study was conducted among 701 youths in Addis Ababa from September 1st to 30th, 2023. The quantitative data were collected through face to face interview using a pre-tested structured questionnaire, while qualitative data were gathered through in depth interviews and focus group discussions. For the quantitative study, the study samples were chosen using systematic sampling. Conversely, purposive sampling was employed for the qualitative study. Variables with P-value ≤ 0.25 in the bivariate analysis were considered as candidates for the multivariable analysis. Statistical significance was declared at a P-value less than 0.05.

RESULTS

The prevalence of risky sexual behavior among out of school students in Addis Ababa was 40.6% (95%CI: 36.8, 44.1). Age 15-19 years (AOR: 2.52; 95%CI: 1.61, 3.94), being female (AOR: 2.84; 95%CI: 1.93, 4.18), fathers who were unable to read and write (AOR: 4.13; 95%CI: 2.04, 8.37), alcohol consumption (AOR: 2.07; 95%CI: 1.33, 3.19), peer pressure (AOR: 2.59; 95%CI: 1.81, 3.72), live together with either of biological parent (AOR: 2.32; 95%CI: 1.52, 3.55), watching pornography (AOR: 2.10; 95%CI: 1.11, 3.97) and parental monitoring (AOR: 0.59; 95%CI: 0.39, 0.90) were factors associated with risky sexual behavior.

CONCLUSION AND RECOMMENDATIONS

A lower prevalence of risky sexual behavior compared to prior research efforts. Age, gender, educational level of the husband, alcohol consumption, peer pressure, living arrangements, exposure to pornography, and family monitoring emerged as significant factors associated with risky sexual behavior. Therefore, government should prioritize strategies to reduce substance use, mitigate the impact of watching pornography, and enhance parent-youth connectedness.

Effectiveness of a School-Based Pregnancy Prevention Intervention for Female Teenagers and Their Boyfriends: A Randomized Controlled Trial

PURPOSE

This study examined the effectiveness of a school-based pregnancy prevention intervention.

METHODS

73 female and male teenagers were recruited from an urban secondary school and randomly assigned to the intervention and control groups. The females were aged 13-15 years, and the boyfriends were aged 13-18 years. The intervention was implemented in six sessions over six weeks. Sessions 1-4 were conducted at the school, and sessions 5-6 were delivered via a smartphone messaging application. The outcomes included sexual health literacy, pregnancy prevention behaviors, and sexual risk behaviors. They were measured three times: at baseline (week 0, T1), immediately post-intervention (week 6, T2), and follow-up (week 10, T3). Two-way mixed repeated measure ANOVA was used to determine the differences of the outcomes.

RESULTS

After completion of the intervention, participants in the intervention group had significantly higher sexual health literacy both at T2 and T3 and better pregnancy prevention behavior. They had lower sexual risk behaviors at T3 than the control group.

DISCUSSION

The results indicate that the school-based pregnancy prevention intervention is effective. It improved the outcomes in female teenagers and their boyfriends at six weeks and 10 weeks post-intervention.

Knowledge and practice of high school students regarding HIV/AIDS prevention and transmission: Results from a cross-sectional study in an Iranian less-developed, high-risk region

BACKGROUND

Some residents of the Persian Gulf Coastline (PGC) areas are circular migrants due to geo-commercial issues. They have a higher risk of HIV infection and non-disclosure of their HIV/AIDS status. These people who live with HIV (PLHIV) are considered as the bridge population for HIV transmission to general population, especially adolescents. This study sought to investigate the knowledge and behavior of adolescents regarding HIV/AIDS prevention and transmission in a less-developed, high-risk area located along the PGC.

MATERIALS AND METHODS

In this cross-sectional study, using multistage cluster random sampling, 1450 students were invited to complete a standardized questionnaire previously used in a 2013 Iranian national high-risk behaviors survey. The prevalence of adequate knowledge, condom use, and stigmatization of HIV/AIDS and their 95% confidence intervals (CIs) were estimated. Adjusted odds ratios (ORs) were estimated using ordinal logistic regression.

RESULTS

Totally, 17.09% (CI: 15.0-19.3) of the students had adequate knowledge. Social networks and the internet were the most important sources of information (20.9%, CI: 18.6-23.3). Socioeconomic status (OR: 2.0, 95% CI: 1.7-2.3), gender (0.6, CI: 0.5-0.8), residential area (0.08, CI: 0.05-0.1), and using social networks and the internet as the main sources of information (1.5, CI: 1.1-1.9) were correlated to the level of knowledge. Furthermore, 29.8% (CI: 27.2-32.5) of the students respected the social rights of PLHIV, and 12.6% (CI: 10.7-14.6) reported condom use.

CONCLUSION

HIV/AIDS-related education is needed in the PGC. Such education should be focused on males, students from marginalized areas, and people with lower socioeconomic status. Social networks and the internet may be the most effective way to improve people's knowledge about HIV/AIDS.

Alcohol and drug use during sex and its association with sexually transmitted infections: a retrospective cohort study among young people aged under 25 years visiting Dutch STI clinics

INTRODUCTION

Alcohol use and drug use are common behaviours among young people. STI positivity is higher in young people than in people aged above 25 years. While there is an increasing amount of knowledge about drug use during sex among men who have sex with men (MSM), data on this behaviour among young women and heterosexual men are scarce. Therefore, this study aims to assess the proportion and characteristics of women and heterosexual men aged under 25 years reporting alcohol and/or drug use during sex and its association with STI positivity.

METHODS

Surveillance data of heterosexual individuals younger than 25 years visiting two Dutch STI clinics between 2016 and 2019 were assessed (n=11 714). We used multivariable logistic regression analyses to assess associations between alcohol and drug use during sex and STI positivity (Chlamydia trachomatis and/or Neisseria gonorrhoeae diagnosis), adjusting for sociodemographic characteristics (sex, age, ethnicity, educational level, socioeconomic status and urbanisation) and sexual behaviour (condom use, number of sex partners).

RESULTS

Alcohol use during sex was reported by 45.3% (5311/11 714; 49.5% in men vs 43.2% in women, p<0.001) and drug use during sex by 22.0% (2580/11 714; 30.7% in men vs 17.6% in women, p<0.001). The most reported drugs were cannabis (17.9%), ecstasy (XTC)/methylenedioxymethamphetamine (MDMA) (6.9%) and cocaine (4.7%). The use of at least one of the following drugs (XTC/MDMA, cocaine, speed, ketamine, gamma-hydroxybutyrate (GHB)/gamma-butyrolactone (GBL), heroin, crystal meth and/or designer drugs) was significantly associated with STI positivity after adjustment for sociodemographic characteristics (adjusted OR (aOR): 1.3, 95% CI 1.1 to 1.4), but this association did not remain significant after adjustment for sexual behaviour (aOR: 1.12, 95% CI 0.94 to 1.34). Significant associations between drug use during sex and inconsistent condom (aOR: 2.5, 95% CI 1.9 to 3.2) use and having four or more sex partners (aOR: 3.2, 95% CI 2.8 to 3.6) in the past 6 months were assessed.

DISCUSSION

Alcohol and drug use during sex was highly prevalent among young women and heterosexual men visiting the STI clinic and drug use during sex was associated with an increased risk for STI, probably mediated by sexual behaviour. This indicates that a holistic health promotion strategy, addressing STI prevention and alcohol and drug use-related harm reduction, is important in this group. STI clinics should address this behaviour not only among MSM, but also among young women and heterosexual men.

Does #Tamojunto alter the dynamic between drug use and school violence among youth? Secondary analysis from a large cluster-randomized trial

The present study investigated how intervention might alter the relationship between perpetrating violence and later drug use. A cluster-randomized controlled trial design involving 72 schools (38 intervention, 34 control) and 6390 students attending grades 7 and 8 was employed in Brazil. Drug use and violence were assessed at three points. A random-intercept cross-lagged panel model examined the reciprocal association between drug use and school violence domains across the three data collection waves. For both groups, we found that the cross-lagged effect of perpetration on further drug use in adolescents was stronger than the reverse, but the interrelationship was not statistically significant between #Tamojunto and control schools. The carry-over effects of drug use and violence were also not significantly different between groups. There is a lack of evidence showing that #Tamojunto can modify the dynamics between drug use and school violence across the 21-month period. The direction of the causal effect (i.e., the more perpetration behavior, the more subsequent drug use behavior) is present, but weak in both groups. The trial registration protocol at the national Brazilian Register of Clinical Trials (REBEC) is #RBR-4mnv5g.

Relationship Between Alcohol Consumption and Risky Sexual Behaviors Among Adolescents and Young Adults: A Meta-Analysis

Objectives: Adolescents exposed to alcohol have increased risky sexual behaviors (RSBs); however, the association between alcohol consumption and RSBs has to be systematically and quantitatively reviewed. We conducted a meta-analysis of the literature to systematically and quantitatively review the association between alcohol consumption and RSBs in adolescents and young adults. Methods: We searched for qualified articles published from 2000 to 2020 and calculated pooled odds ratios (ORs) using the random-effect model. We also conducted meta-regression and sensitivity analyses to identify potential heterogeneity moderators. Results: The meta-analysis of 50 studies involving 465,595 adolescents and young adults indicated that alcohol consumption was significantly associated with early sexual initiation (OR = 1.958, 95% confidence interval (CI) = 1.635-2.346), inconsistent condom use (OR = 1.228, 95% CI = 1.114-1.354), and having multiple sexual partners (OR = 1.722, 95% CI = 1.525-1.945). Conclusion: Alcohol consumption is strongly associated with RSBs, including early sexual initiation, inconsistent condom use, and multiple sexual partners among adolescents and young adults. To prevent the adverse consequences of alcohol consumption, drinking prevention programs should be initiated at an early age and supported by homes, schools, and communities.

Influence of preventive sex education programmes in compulsory secondary education students: a descriptive observational study

BACKGROUND

Sex education programmes conducted by health professionals and educators are essential for young people to adopt healthy habits and attitudes towards their sexuality. The Forma Joven Program, promoted by the Andalusian Regional Government's Ministry of Health and Families and Education, is a good example of this. The aim of the study is to determine if different "degrees of intervention" in the informative consultancies of the Forma Joven Program imply differences in knowledge and attitudes towards sexuality.

METHODS

This descriptive observational study analysed 27 Compulsory Secondary Education high schools in Huelva. These were included in the Program and belonged to a Primary Care Health District. Out of the 17 institutes initially selected because they met the inclusion criteria (4.256 students), finally 14 (3.596 students) participated. During the 2018/2019 school year, students from 3rd, 4th year of Secondary Compulsory Education (ESO), 1st, and 2nd Baccalaureate of the selected centres were asked to fill in a questionnaire of knowledge and attitudes towards sexuality. It collected variables such as age, sex, school year, institute, educational level and employment status of the father or mother and profile of the professional who delivers the counselling.

RESULTS

A total of 1.237 students completed the questionnaire, which represents a participation rate of 34.4%. The average age was 15.59 years (SD 1.26) and 39.9% were girls. In some evaluated questions, we found statistically significant differences between the groups with different levels of exposure to counselling and the acquisition of knowledge and attitudes towards students' sexuality, although in most of them no such differences were found. The results of this study suggest the importance of the quality of counselling over quantity. Some classic myths persist in relation to sexuality and in some situations, they can be decisive when adopting preventive measures to avoid risks related to pregnancy and contagion of STIs.

CONCLUSIONS

A greater number of counselling sessions does not imply acquiring a higher level of knowledge or better attitudes towards sexuality. Perhaps the quality of the education is more important than the quantity of counselling sessions.

Risky sexual behavior and associated factors among sexually experienced secondary school students in Guduru, Ethiopia

Adolescents at secondary schools are susceptible to engaging in risky sexual behavior (RSB) due to their teenage stage and the new environment they face. Limited researches in district towns have evaluated the RSB among adolescents with various findings. This study aimed to assess the RSB and associated factors among sexually experienced secondary school students. School-based cross-sectional study was conducted in Guduru district from March 4-8, 2019. A total of 1236 secondary school students were undergoing a survey. The data were collected using a pretested anonymously self-administered questionnaire and students who reported having ever had sex were evaluated for RSB. From all participants, 352 (29.8%) had ever started sexual intercourse from which 240 (68.2%) students were involved in RSB. During the multivariable logistic regression analysis, sex (AOR: 3.73; 95%CI: [1.71-8.14]), father educational level (AOR: 0.37; 95%CI: [0.16-0.84]), drinking alcohol (AOR: 2.76; 95%CI: [1.29-5.69]), perceived peer pressure (AOR: 4.22; 95%CI: [1.59, 11.24]), communication with parents (AOR: 9.58, 95%CI: [3.53, 25.94]), and perceived parental monitoring (AOR: 0.33; 95%CI: [0.14-79]) were significantly associated with RSB. This study outlined that the majority of sexually active adolescents are involved in RSB. Interventions at the health facility and school level should focus on the identified determinants of sexual behaviors among adolescents to minimize the risky consequences.

Sexual risk behaviour and its correlates among adolescents in Mozambique: results from a national school survey in 2015

The study aimed to assess the prevalence and correlates of sexual risk behaviours among adolescents in Mozambique. In the cross-sectional 'Global School-Based Health Survey (GSHS)', 1918 students aged 11-18 years from Mozambique responded to a questionnaire in 2015. More than half (57.4%) of the students ever had sex, 68.4% among boys and 45.8% among girls. Among students who ever had sex, 41.5% had early sexual debut (<14 years), 57.9% had multiple sexual partners, 25.0% had not used a condom and 42.0% had not used birth control at last sex, and 59.4% engaged in multiple sexual risk behaviour. In adjusted logistic regression analysis, alcohol use, school truancy, older age and male sex were associated with multiple sexual risk behaviours. A large number of adolescents in Mozambique reported sexual risk behaviours, emphasising the need for interventions.

Substance use amongst high school learners in the south of Johannesburg: Is this the new norm?

Background

Substance use amongst high school learners is common in South Africa, with related risky behaviours and outcomes. Because of the social and geographical trends, studies in various parts of the country are essential to contribute to the understanding of the overall picture. The purpose of this study was to determine the prevalence of substance use, as well as the factors associated with substance use in a sample of high school learners in a suburb south of Johannesburg.

Methods

A quantitative cross-sectional survey, by using a self-administered questionnaire, was conducted amongst 308 learners in four high schools. The parents of all the learners provided consent for their children to participate in the study.

Results

The sample consisted of 308 learners who were in grades 8–12, with a mean age of 16.3. The majority (57%, n = 177) were females and 43% (n = 131) were males. The prevalence of substance use was 31% (n = 94), with 52% (n = 49) of those who use substances being male, compared with 48% (n = 45) females. Of those who used substances, 69% (n = 65) used alcohol, 10% (n = 9) smoked dagga, 5% (n = 5) smoked cigarettes, 7% (n = 7) used other substances and 46% (n = 43) were polyusers. Age, missing school because of illness, use of leisure time and friends using substances were significantly associated with the use of substances (p < 0.05).

Conclusion

The prevalence of substance use was high at 31%, which is of concern because the use of legal psychoactive substances remains illegal for minors. The risky factors associated with the use of substances highlight the threat that this behaviour has on the social well-being and educational outcomes of the learners.

Prevalence and Correlates of Sexual Risk Behavior among School-Going Adolescents in Four Caribbean Countries

This study aimed to assess the prevalence and correlates of sexual risk behaviors among adolescents in the Caribbean. Nationally representative cross-sectional data were analyzed from 9143 adolescents (15 years = median age) that took part in the 2016 Dominican Republic, 2016 Suriname, 2017 Jamaica, and 2017 Trinidad and Tobago Global School-Based Student Health Survey (GSHS). The results indicate that 41.4% of the students had ever had sex, ranging from 26.4% in Trinidad and Tobago to 48.1% in Jamaica. Among the sexually active, 58.8% had had ≥2 sexual partners; 58.6% had had an early sexual debut (≤14 years); 41.9% had not used birth control the last time they had sex; 28.4% had not used a condom the last time they had sex; and, of the whole sample, 31.9% had engaged in two or more (multiple) sexual risk behaviors, ranging from 16.5% in Trinidad and Tobago to 40.3% in Jamaica. In an adjusted logistic regression analysis, substance use (tobacco, alcohol, and cannabis), psychological distress, frequent soft drink intake, participation in physical fighting, school truancy, older age, and male sex were associated with single and/or multiple sexual risk behaviors. A large number of adolescents in the Caribbean reported sexual risk behaviors, emphasizing the need for intervention.

Sexual risk behaviour and its correlates among adolescents in Indonesia, Laos, Thailand and Timor-Leste: results from national school surveys in 2015

OBJECTIVES

The study aimed to assess the prevalence and correlates of sexual risk behaviours among adolescents in four Southeast Asian countries.

METHODS

In the cross-sectional "Global School-Based Student Health Survey (GSHS)", 24,423 adolescents (mean age 14.1 years, SD=1.7) from Indonesia, Laos, Thailand and Timor-Leste responded to a questionnaire in 2015.

RESULTS

Overall, 8.5% of the students (11.0% males and 6.3% females) ever had sex, ranging from 5.3% in Indonesia to 26.4% in Timor-Leste. Among the sexually active, 49.3% (55.9% males and 36.8% females) had their first sexual intercourse before the age 14 years, ranging from 16.1% in Laos to 73.9% in Indonesia, 59.7% (62.6% males and 53.5% females) had multiple sexual partners, ranging from 55.5% in Timor-Leste to 63.4% in Indonesia, 46.9% (46.8% males and 46.5% females) did not use a condom at last sex, ranging from 37.0% in Thailand to 65.3% in Indonesia, 49.8% (53.7% males and 43.7% females) had not used or did not know of the use of birth control at last sex, ranging from 40.6% in Thailand to 61.5% in Timor-Leste, and 54.2% (54.9% males and 47.0% females) engaged in multiple sexual risk behaviour, ranging from 45.9% in Laos to 78.0% in Indonesia. In adjusted logistic regression analysis, male sex, older age, food insecurity, tobacco use, alcohol use, ever cannabis and/or amphetamine use, psychological distress, and school truancy were associated with two or more and/or multiple sexual risk behaviours.

CONCLUSIONS

A high proportion of students engaged in various sexual risk behaviours calling for a scale up comprehensive sexuality education and integration of substance use and mental health into such intervention programmes in this adolescent school population.

Risky sexual behavior and associated factors in undergraduate students in a city in Southern Brazil

OBJECTIVE

To describe the sexual behavior of freshmen undergraduate students according to demographic, economic, psychosocial and behavioral characteristics, and evaluate the prevalence of risky sexual behavior and its associated factors.

METHODS

A cross-sectional study of the census type with undergraduate students over 18 years old of 80 undergraduate courses of the Universidade Federal de Pelotas (UFPel), in Rio Grande do Sul (RS), who entered in the first semester of 2017 and remained enrolled in the second semester. Undergraduate students who reported having had sex were evaluated. We considered as risky sexual behavior having more than one sexual partner within the last three months and not having used condoms in the last sexual intercourse.

RESULTS

The prevalence of risky sexual behavior was 9% (95%CI 7.6–10.5). Men presented more risky behavior than women, with a prevalence of 10.8% and 7.5%, respectively. Of the undergraduate students, 45% did not use condoms in the last sexual intercourse, and 24% had two partners or more within three months before the survey. Smartphone applications for sexual purposes were used by 23% of students within three months before the survey. Risky sexual behavior was associated with gender, age at first sexual intercourse, frequency of alcohol consumption, consumption of psychoactive substances before the last sexual intercourse and use of smartphone applications for sexual purposes.

CONCLUSION

Although undergraduate students are expected to be an informed population, the prevalence of risky sexual behavior was important, indicating the need to expand public investment in sexual education and awareness actions.

Contradições acerca da violência sexual na percepção de adolescentes e sua desconexão da lei que tipifica o “estupro de vulnerável”

Resumo: O Art. 217-A da Lei nº 12.015/2009 definiu como crime de estupro de vulnerável a conjunção carnal ou outro ato libidinoso praticados com menor de 14 anos. Diante da baixa idade de início da atividade sexual observada na atualidade, objetivamos neste estudo compreender a concepção de adolescentes acerca da iniciação sexual, da violência sexual e da lei que a tipifica como “estupro de vulnerável”. Utilizamos método qualitativo por meio de 13 grupos focais com 132 estudantes do Ensino Médio de escolas públicas e privadas do Município do Rio de Janeiro, Brasil. A análise dos dados foi realizada com apoio do software webQDA, em uma abordagem hermenêutico-dialética que deu origem a três categorias: sentir-se apto a iniciar o sexo, (in)vulnerabilidade à violência sexual e mecanismos de proteção. A iniciação sexual para as moças está relacionada a uma visão romântica, a se sentirem seguras e terem confiança no parceiro, ao passo que, para os rapazes, está associada a oportunidade, livre de outros fatores. Para a maioria dos estudantes, quando o consentimento para a prática sexual é mútuo, independente da idade, não há violência. Ao mesmo tempo, questionam-se quanto à capacidade de discernimento das mais jovens para permitir o sexo. A maior parte discorda das medidas protetivas previstas na lei, por entender que é dever da família prover esse cuidado. As contradições na percepção dos adolescentes sobre a vulnerabilidade à violência sexual e o estupro de vulnerável previsto em lei nos levam a concluir que é necessário ampliar e qualificar a educação sexual de forma abrangente para adolescentes, assim como criar espaços de discussão que possam proporcionar aperfeiçoamento desse dispositivo legal.

Association between sociodemographic characteristics and sexual behaviors among a nationally representative sample of adolescent students in Brazil

Although low socioeconomic status (SES) adolescents suffer from higher rates of adverse sexual and reproductive health outcomes, evidence on the association between SES and sexual behaviors has been less consistent. A cross-sectional analysis of the association between sociodemographic characteristics (household wealth, maternal education and race/ethnicity) and sexual behaviors (sexual initiation, multiple sexual partners, inconsistent condom use and inconsistent contraceptive use) of Brazilian adolescents was carried out using the 2015 Brazilian National Survey of School Health (PeNSE), a nationally representative school-based survey of 102,301 adolescents. Analyses included multivariable logistic models, which accounted for geographic and family characteristics. About 27.5% of adolescents were sexually initiated. Household wealth was associated with female sexual initiation, while race/ethnicity was associated with condom use and multiple sexual partners among males. For instance, black males had 35% higher odds of having multiple partners (aOR = 1.35, 95%CI: 1.13-1.62), but 22% lower odds of condom use (aOR = 0.78, 95%CI: 0.65-0.94), compared to white males. Frequent parental supervision was positively related to condom use (females, aOR = 1.28, 95%CI: 1.10-1.49; and males, aOR = 1.33, 95%CI: 1.18- 1.49). Results show the complex relationship between SES and sexual behaviors. Researchers should pay attention to gender, racial and social norms salient to adolescent sexual behaviors, as they can influence data collection and results. National policies should also support active parental supervision, since it can be a protective factor.

Alcohol misuse among women in Brazil: recent trends and associations with unprotected sex, early pregnancy, and abortion

Objective:

This study compared the rates of binge drinking (BD) and alcohol use disorder (AUD) reported for 2006 with those reported for 2012, exploring their associations with unprotected sex, early pregnancy, and abortion in a representative sample of women in Brazilian households.

Methods:

This was a descriptive analysis of data from a cross-sectional study involving randomized multistage cluster sampling of the population ≥ 14 years of age. Weighted prevalence rates and odds ratios were estimated, and serial mediation analysis was performed.

Results:

A total of 4,256 women were analyzed. The BD prevalence was 35.1% and 47.1% in 2006 and 2012, respectively, a significant increase, especially among women 40-59 years of age. There was no significant difference in AUD prevalence. BD (without AUD) was found to increase the odds of unprotected sex and abortion. The path analysis showed that early pregnancy was a mediator of the relationship between alcohol consumption and abortion.

Conclusion:

Among women in Brazil, the harmful use of alcohol is increasing, which has an impact on female reproductive health and exposure to risks. There is a need for specific prevention initiatives focusing on alcohol-related behaviors in women.

Oral Health Impact Profile and Associated Variables in Southern Brazilian Drug Users

BACKGROUND

This study investigated the association between sociodemographic, behavioral, oral health, variables of drug consumption, and the short version of the Oral Health Impact Profile (OHIP-14), in Southern Brazilian drug users.

METHODS

In this cross-sectional study, 202 drug users aged 18 or over admitted for treatment at the Institute for Research and Treatment of Alcoholism (Instituto de Pesquisa e Tratamento do Alcoolismo -IPTA) from the municipality of Campo Largo, PR, Brazil, from 2012 to 2014, were involved. They answered a questionnaire and were examined by a calibrated researcher. Data were collected and bivariate (Chi-square test) and multivariate (logistic regression and Wald's test) analyses were performed.

RESULTS

There was statistical difference (P<0.05) in bivariate analysis and the worst impacts were reported by non-whites, those who reported feeling metallic taste in mouth and tooth mobility, which use cigarettes for over 15 yr and consume more than 3 g of crack/day, with DMFT >10, and number of teeth in mouth ≤27. In the multivariate analysis, statistical difference remained, except for ethnicity (P=0.207).

CONCLUSION

Self-perception of oral health was associated with the variables explored, which suggests the need for strategies focused on this population.

Sexual behavior across the transition to adulthood and sexually transmitted infections: Findings from the national survey of human papillomavirus prevalence (POP-Brazil)

The sexual behaviors of 15- to 24-year-olds increase the risk of this population to acquire sexually transmitted infections (STIs). The present study aimed to describe the sexual behavior in the transition to adulthood Brazilian population and its association with STI history.We analyzed cross-sectional data collected from 8562 sexually active women and men who participated in the National Survey of Human Papillomavirus Prevalence (POP-Brazil). This large-scale survey enrolled participants from 26 Brazilian capitals and the Federal District. Professionals from primary care facilities were trained to collect data utilizing a standardized questionnaire with questions on sociodemographic, sexual behavior, and drug use. We constructed a Poisson model with robust variance for both crude and adjusted analysis to investigate the associations between the variables. To adjust the distribution of the sample to the study population, we weighted the measures by the population size in each city and by gender.There were differences in several aspects from sexual behavior between genders. The majority of men reported an early sexual initiation, more sexual partners, and a different practice in sexual positions when compared with women. Women reported use of contraception more frequently than men (P < .001). The use of alcohol and drugs and the use of drugs before sexual intercourse impact in STIs equally between the genders. Exclusive for women, the presence of any STI was associated with the practice of vaginal sex and other types of intercourse (adjusted prevalence ratio [APR] 1.43, 95% CI 1.08-1.88). For men, the number of sexual partners in the last year (APR 1.02, 95% CI 1.01-1.04), not having vaginal sex (APR 3.25, 95% CI 1.78-5.92) and sexual experience with someone of the same sex (APR 4.05, 95% CI, 2.88-5.70) were associated with a higher presence of STIs.This is the first report regarding sexual behavior in a nationally representative population sample in Brazil. This study provides more valid estimates of sexual behavior and associated STIs, identifying important differences in sexual behavior and identifying predictors for referred STIs among females and males.

Drug use prevention: factors associated with program implementation in Brazilian urban schools

Background

A school is a learning environment that contributes to the construction of personal values, beliefs, habits and lifestyles, provide convenient settings for the implementation of drug use prevention programs targeting adolescents, who are the population group at highest risk of initiating drug use. The objective of the present study was to investigate the prevalence of factors associated with implementing drug use prevention programs in Brazilian public and private middle and high urban schools.

Methods

The present population-based cross-sectional survey was conducted with a probability sample of 1151 school administrators stratified by the 5 Brazilian administrative divisions, in 2014. A close-ended, self-reported online questionnaire was used. Logistic regression analysis was used to identify factors associated with implementing drug use prevention programs in schools.

Results

A total of 51.1% of the schools had adopted drug use prevention programs. The factors associated with program implementation were as follows: belonging to the public school network; having a library; development of activities targeting sexuality; development of “Health at School Program” activities; offering extracurricular activities; and having an administrator that participated in training courses on drugs.

Conclusions

The adoption of drug use prevention practices in Brazilian schools may be expanded with greater orchestration of schools through specialized training of administrators and teachers, expansion of the School Health Program and concomitant development of the schools’ structural and curricular attributes.

Cross-cultural adaptation and validation of the Condom Self-Efficacy Scale: application to Brazilian adolescents and young adults

Objective:

translate and adapt the Condom Self-Efficacy Scale to Portuguese in the Brazilian context. The scale originated in the United States and measures self-efficacy in condom use.

Method:

methodological study in two phases: translation, cross-cultural adaptation and verification of psychometric properties. The translation and adaptation process involved four translators, one mediator of the synthesis and five health professionals. The content validity was verified using the Content Validation Index, based on 22 experts’ judgments. Forty subjects participated in the pretest, who contributed to the understanding of the scale items. The scale was applied to 209 students between 13 and 26 years of age from a school affiliated with the state-owned educational network. The reliability was analyzed by means of Cronbach’s alpha.

Results:

the Portuguese version of the scale obtained a Cronbach’s alpha coefficient of 0.85 and the total mean score was 68.1 points. A statistically significant relation was found between the total scale and the variables not having children (p= 0.038), condom use (p= 0.008) and condom use with fixed partner (p=0.036).

Conclusion:

the Brazilian version of the Condom Self-Efficacy Scale is a valid and reliable tool to verify the self-efficacy in condom use among adolescents and young adults.

Association between the risk of alcohol use and unprotected sex in adolescents in a city in the southern region of Brazil

This paper aims to analyze alcohol abuse and unprotected sex and the association between them in students in a city in the southern region of Brazil. This is a cross-sectional study using a quantitative approach with 590 secondary school students from two public schools. Regarding alcohol use, 14% scored from eight to 40 in The Alcohol Use Disorders Identification Test (AUDIT), which means, at least, a risky drinking behavior, with higher rate among boys. Moreover, 31.1% indulged themselves in binge drinking, which means drinking six or more doses according to AUDIT; and even among those who are low- risk drinkers, 21.1% had this drinking pattern. Regarding sexual behavior, young boys started sexual life earlier and the kind of relationship more referred to by them is one with no commitment; boys have uncommitted relationships, while girls have more relationships with commitment. In relation to the results of the association between alcohol use and sexual intercourse, 47.3% stated alcohol use before having sex, and those who started sexual activity got more drunk and had higher scores in the AUDIT. New studies are recommended regarding the association between both behaviors in Brazil, considering that the causal relationship is not clear and shows several explanation models.

[Contraception in Mexican adolescents in upper secondary schools: use and unmet needs]

OBJECTIVE

To describe sexual behavior and contraceptive use in adolescent students.

MATERIALS AND METHODS

National representative survey in upper secondary schools in Mexico 2014. Logistic regressions identify the factors associated with contraceptive use and unmet needs for contraception (UNC).

RESULTS

For male adolescents, non-contraceptive use in the last sexual relation is associated with non-contraceptive use in the sexual debut (OR=11.5; IC95%:5.6,23.4) and not recognizing effective contraceptive methods (OR=2.4;IC95%:1.04,5.5). For female adolescents, non-contraceptive use is associated with non-contraceptive use in sexual debut (OR=4.5;IC95%:2.3,8.4) and low self-efficacy towards condom use and negotiation (OR=3.1; IC95%:1.1,8.2). UNC were associated with insecure attitudes towards condom use and negotiation (OR=3.5;IC95%:1.3,9.4), non-contraceptive use in sexual debut (OR=9.0;IC95%:2.5,32.4) and use of alcohol or drugs during sexual relations (OR=3.0;IC95%:1.1,8.1).

CONCLUSIONS

Strategies to ensure contraceptive use from sexual debut onwards are required, promoting self-efficacy and safe sex practices among adolescents.

Minority Men Who Have Sex with Men Demonstrate Increased Risk for HIV Transmission

Black and Hispanic (minority) MSM have a higher incidence of HIV than white MSM. Multiple sexual partners, being under the influence of drugs and/or alcohol during sex, having a detectable HIV-1 RNA, and non-condom use are factors associated with HIV transmission. Using data from the Veterans Aging Cohort Study, we consider minority status and sexual orientation jointly to characterize and compare these factors. White non-MSM had the lowest prevalence of these factors (p < 0.001) and were used as the comparator group in calculating odds ratios (OR). Both MSM groups were more likely to report multiple sex partners (white MSM OR 7.50; 95 % CI 5.26, 10.71; minority MSM OR 10.24; 95 % CI 7.44, 14.08), and more likely to be under the influence during sex (white MSM OR 2.15; 95 % CI 1.49, 3.11; minority MSM OR 2.94; 95 % CI 2.16, 4.01). Only minority MSM were more likely to have detectable HIV-1 RNA (OR 1.87; 95 % CI 1.12, 3.11). Both MSM groups were more likely to use condoms than white non-MSM. These analyses suggest that tailored interventions to prevent HIV transmission among minority MSM are needed, with awareness of the potential co-occurrence of risk factors.

Energy drink enhances the behavioral effects of alcohol in adolescent mice

Mixing alcohol with energy drinks has become increasingly popular among teenagers and young adults due to the prevailing view that the stimulant properties of energy drinks decrease the depressant effects of alcohol. Surprisingly, in spite of energy drinks being heavily marketed to and consumed by adolescents, there is scarcely available preclinical data on the neurobehavioral effects of energy drinks mixed with alcohol during adolescence. Thus, here we examine the effects of the combined exposure to alcohol and energy drink on adolescent mice using a variety of behavioral tasks to assess locomotor activity, righting reflex and motor coordination. At postnatal day 40, male and female Swiss mice were assigned to the following experimental groups: alcohol diluted in energy drink (Ed+Etoh), alcohol diluted in water (Etoh) or controls (Ctrl: energy drink or water). Alcohol and energy drink (Red Bull) concentrations were 4g/kg and 8ml/kg, respectively, and all solutions were administered via oral gavage. When compared to Etoh mice, Ed+Etoh animals displayed greater locomotor activity and increased anxiety-like behaviors in the open-field, lost their righting reflexes sooner and displayed poorer motor coordination in the rotarod. Collectively, our findings indicate that alcohol-induced deficits in adolescent mice are worsened by energy drink and go against the view that the stimulant properties of energy drinks can antagonize the adverse effects of alcohol.

Condom use and alcohol consumption in adolescents and youth

OBJECTIVE

To determine the association between not using the male condom and alcohol consumption in adolescents and schoolchildren.

METHODS

An epidemiological study, with a cross-sectional, descriptive, and correlation design carried out from March to July 2014. The sample consisted of students in public primary and secondary education, aged between 12 and 24 years. The social and demographic survey and the Youth Risk Behavior Survey questionnaire were used.

RESULTS

The study included 1,275 students, of these; 37.0% reported having had sexual relations. The prevalent age of sexual initiation was 14-16 years 55.7% and 65.6% used condom in the last sexual intercourse. Regarding the lack of condom use at the last intercourse, girls showed an association with drunkenness in the previous 30 days (2.19; 95%CI: 1.06-4.54).

CONCLUSION

In females, the non-use of condoms was associated with drunkenness in the previous 30 days.

OBJETIVO

Identificar os fatores associados ao não uso de preservativo masculino e ao consumo de bebida alcoólica em adolescentes e jovens escolares.

MÉTODOS

Estudo epidemiológico, com delineamento transversal, descritivo e correlacional, desenvolvido de março a julho de 2014. A amostra foi composta por estudantes dos Ensinos Fundamental e Médio da rede pública estadual, com idades entre 12 e 24 anos. Empregaram-se o inquérito sociodemográfico e o questionário Youth Risk Behavior Survey.

RESULTADOS

Foram incluídos 1.275 estudantes; 37,0% deles relataram terem tido relação sexual. A idade prevalente de iniciação sexual foi de 14 a 16 anos, com 55,7%; 65,6% usaram preservativo na última relação. Com relação ao não uso de preservativo na última relação, as meninas apresentaram associação com bebedeira nos últimos 30 dias (2,19; IC95%: 1,06-4,54).

CONCLUSÃO

O não uso de preservativos esteve associado com bebedeira nos últimos 30 dias nas meninas.

Association between the number of sexual partners and alcohol consumption among schoolchildren

OBJECTIVE

To determine the association between the number of sexual partners and alcohol consumption in adolescents and young schoolchildren.

METHODS

The sample consisted of students from public schools aged 12-24 years who answered the Brazilian version of the Youth Risk Behavior Survey questionnaire. The analysis was performed by multinomial logistic regression model.

RESULTS

1275 students were analyzed. For females, having two to five partners was associated with age ≥15 years (OR 14.58) and maternal education up to incomplete high school or lower educational level (OR 3.37). No consumption of alcohol decreased the chances of having more partners by 96%. For males, the associated variables were: age ≥15 years (OR 18.15); having no religion (OR 3.55); age at first dose ≤14 years (OR 3.48). Binge drinking increases the chances of having a higher number of sexual partners.

CONCLUSION

Regardless of the number of partners, binge drinking and age of alcohol consumption onset are risk factors for vulnerable sexual behavior.

Factors associated with the implementation of programs for drug abuse prevention in schools

OBJECTIVE

To analyze if characteristics of managers, schools, and curriculum are associated with the implementation of programs for drug abuse prevention in elementary and high schools.

METHODS

Cross-sectional study, with random sample of 263 school managers. Data were collected between 2012 and 2013 by a program that sends forms via internet. A closed self-filling questionnaire was applied online. Statistical analysis included Chi-square tests and logistic regression models. The outcome variable was the presence of program for drug abuse prevention inserted in the daily life and educational program of the school. The explanatory variables were divided into: demographic data of the manager; characteristics of the school and of the curriculum; health education; and drug use in the school.

RESULTS

We found that 42.5% (95%CI 36.1-49.1) of the evaluated schools had programs for drug abuse prevention. With the multiple logistic regression model, we observed that the more time the manager has worked with education, the chance of the school having a program increased at about 4.0%. Experimenting with innovative teaching techniques also increased at about six times the chance of the school developing a program for drug abuse prevention. The difficulties in the implementation of the programs were more present in state and municipal schools, when compared with private schools, due to, for instance: lack of teaching materials, lack of money, and competing demands for teaching other subjects.

CONCLUSIONS

The implementation of programs for drug abuse prevention in the city of Sao Paulo is associated with the experience of the manager in education and with the teaching strategies of the school.

OBJETIVO

Analisar se características dos dirigentes, das escolas e do currículo escolar estão associadas à implantação de programas de prevenção ao uso de drogas nas escolas do ciclo fundamental II e médio.

MÉTODOS

Estudo transversal, com amostra aleatória sistemática de 263 dirigentes escolares. Os dados foram coletados nos anos de 2012 e 2013 por meio de um programa de envio de formulários pela internet. Aplicou-se questionário fechado, de autopreenchimento on-line. A análise estatística incluiu testes Qui-quadrado e modelos de regressão logística. A variável desfecho foi a presença de programa de prevenção ao uso de drogas inserido no cotidiano e no programa pedagógico da escola. As variáveis explicativas foram divididas em: dados demográficos do dirigente; características da escola e do currículo; educação em saúde; e consumo de drogas na escola.

RESULTADOS

Constatou-se que 42,5% (IC95% 36,1-49,1) das escolas avaliadas possuíam programa de prevenção ao uso de drogas. Com o modelo de regressão logística múltipla, observou-se que, a cada ano de atuação do dirigente na educação, a chance de a escola ter um programa aumentava em aproximadamente 4,0%. O fato de experimentar técnicas de ensino inovadoras também aumentou em cerca de seis vezes a chance de a escola desenvolver um programa de prevenção ao uso de drogas. As dificuldades na implantação dos programas foram mais presentes nas redes estadual e municipal, quando comparadas à rede privada, destacando-se: a falta de material didático, a falta de dinheiro e as demandas concorrentes para ensino de outras disciplinas.

CONCLUSÕES

A implantação de programas de prevenção ao uso de drogas no município de São Paulo está associada à experiência do dirigente escolar na educação e nas estratégias de ensino da escola.

The effect of face-to-face or group education during pregnancy on sexual function of couples in Isfahan

BACKGROUND

Pregnancy can be in conflict with sexual function which can be affected by physical and psychological changes during pregnancy. Therefore, comparison of the effect of face-to-face education with group education on sexual function during pregnancy in couples was the purpose of this research.

MATERIALS AND METHODS

In this quasi-experimental pre-test post-test study, 64 pregnant couples were selected and randomized in two groups in Isfahan. The data were collected using the triangulation of Female Sexual Function Index (FSFI), Brief form of Sexual Function Inventory (BSFI), and demographic characteristics questionnaires. The data were analyzed by independent t-test, paired t-test, Chi-square, analysis of covariance (ANCOVA), and analysis of variance (ANOVA) in SPSS.

RESULTS

No significant difference was found in the demographic characteristics between the two groups. Education was effective on sexual function in the two groups of women (P < 0.001), but no significant difference was found between the two groups (P = 0.61). Also, education was effective on sexual function of men in both the groups (P < 0.001) and there was a significant difference between the two groups (P = 0.003). Meanwhile, there was no significant difference between couples regarding the education (P = 0.104).

CONCLUSIONS

The results of the study showed that type of education plays a role in improvement of sexual function in pregnancy. In addition, sex education is effective in prevention of sexual disorders in pregnancy. Therefore, having a special approach toward sex education classes during pregnancy is important for the health providers, particularly midwifery professionals.

Influence of risk-taking health behaviours of adolescents on cervical cancer prevention: a Hungarian survey

An anonymous questionnaire survey was conducted among the Hungarian adolescents to establish their use of tobacco, alcohol and drugs in relation to sexual behaviours, knowledge of human papillomavirus (HPV) and cervical cancer, and beliefs and attitudes towards screening and vaccination. Results indicated that adolescent risk-taking health behaviours correlate with risky sexual behaviours. As risk-taking behaviours do not correlate with a better awareness of the risk associated with HPV infection, it is of crucial importance that HPV/cervical cancer preventing educational programmes shall be sensitive to this 'vulnerable' population and draw the attention of these adolescents to their increased risk of sexually transmitted diseases and undesired pregnancies. Well-designed behavioural change interventions may be effective when in addition to providing adolescents (both men and women) with clear information about the implications of an HPV infection, they also aim to improve safer sex behaviours: consistent condom usage, limiting the number of sex partners, as well as encouraging regular participation in gynaecological screenings and uptake of the HPV vaccine. As this study population demonstrated positive attitudes towards the primary and secondary prevention of cervical cancer, the free HPV vaccination for the 12-13-year-old girls in Autumn 2014 will hopefully increase the currently low uptake of the vaccine in Hungary.

Padrão de consumo de álcool e fatores associados entre adolescentes estudantes de escolas públicas em município do interior brasileiro

OBJETIVO: Identificar aspectos relacionados ao consumo alcoólico entre estudantes de um município do interior do sudeste brasileiro. MÉTODOS: Neste estudo transversal foram avaliados 638 alunos de 13 a 17 anos, sendo 355 (55,6%) meninas, escolhidos de modo randomizado em 13/40 (32,5%) escolas públicas entre novembro de 2009 e agosto de 2010. Foi utilizado um questionário estruturado para coleta de dados pessoais/familiares e o Alcohol Use Disorders Identification Test (AUDIT) para avaliar o consumo alcoólico. Foi usada análise bivariada e regressão logística. RESULTADOS: Foi verificado que 516 (80,9%) estudantes fizeram uso de álcool na vida e 115 (18,4%) faziam consumo de risco (AUDIT ≥ 8). Pela análise bruta, o consumo de risco associou-se à faixa etária (16 a 17 anos), idade do primeiro consumo (≤ 12 anos), maior renda familiar, ambiente familiar conflituoso, não praticar uma religião e consumo alcoólico dos pais. Pela análise ajustada observou-se associação com a idade do primeiro consumo (≤ 12 anos), sendo odds ratio (OR) = 2,5 e intervalo de confiança de 95% (IC95%) 1,4 - 4,4. Vida sexual foi mais frequente entre os que já fizeram uso de álcool na vida (OR = 3,3; IC95% 2,0 - 5,3). Sob efeito do álcool, 22/103 alunos (21,4%) nem sempre utilizaram preservativos. Entre todos, 25,4% acreditam que não há risco em beber e 98% já compraram bebidas alcoólicas. Sentir vontade de beber após assistir a propagandas de bebidas alcoólicas foi mais frequente entre adolescentes que já as consumiram (OR = 1,7; IC95% 1,1 - 2,6). CONCLUSÃO: Foi verificado preocupante e precoce consumo alcoólico entre estudantes, mostrando a necessidade tanto de conscientização dos jovens e de seus responsáveis para os riscos desse consumo, quanto de se cumprir a lei que proíbe a venda de bebidas alcoólicas a menores de idade.

Prevalência de sinais e sintomas e conhecimento sobre doenças sexualmente transmissíveis

Objetivo Estimar a prevalência de sinais e sintomas de doenças sexualmente transmissíveis e verificar o conhecimento para essas infecções em adolescentes e jovens de um assentamento urbano. Métodos Estudo de corte transversal realizado em 105 assentados de 12 a 24 anos. Os dados foram coletados por meio de entrevista e analisados pelo Statistical Package for the Social Sciences, versão 17.0. Resultados Do total de participantes que responderam sobre Doenças Sexualmente Transmissíveis, 20,6% relataram algum sinal e/ou sintoma, com maior proporção em indivíduos do sexo feminino, que possuíam piercing e/ou tatuagem e consumiam álcool antes ou durante a relação sexual (p < 0,05). Também, muitos participantes apresentaram desconhecimento quanto os sinais e sintomas de Doenças Sexualmente Transmissíveis. Conclusão A presença de sinais e/ou sintomas de doenças sexualmente transmissíveis foi associado a fatores relacionados à vulnerabilidade individual dos adolescentes e jovens do assentamento.

Who is not using condoms among HIV-positive patients in treatment in the largest city in Brazil?

Data on risky sexual behaviors in people living with HIV/AIDS (PLWHA) is still scarce in some populations around the world. The purpose of this study was to assess the factors associated with the use of condoms in a representative sample of PLWHA in outpatient treatment in the city of São Paulo. Six hundred and sixty-seven HIV-positive patients (383 men and 284 women) who were being treated at eight centers participated in this study. Data were collected using a sociodemographic survey, the Beck depression and anxiety inventories, a survey of alcohol and other drugs use, the Alcohol Use Disorders Identification Test, a sexual behavior survey, and the Sexual Risk Behavior Assessment Schedule. The majority of study participants were sexually active (almost 62% of the sample had at least one sexual partner in the last three months), and at least one-fourth engaged in unsafe sex (25.3% did not use condoms during at least one instance of anal and/or vaginal intercourse in the past three months). Multivariate logistic regression showed that engaging in unprotected sex was more likely among females (p < .001), persons with an HIV-positive partner (p < .001), and people using cannabis before sex (p = .002). These findings should stimulate health-care workers to create specific groups for women, seroconcordant couples, and cannabis users to discuss condom use, as they seem to be vulnerable groups.
