Associated factors and sex differences in condom non-use among adolescents: Brazilian National School Health Survey (PeNSE).

ABSTRACT: BACKGROUND:Condom non-use among sexually active adolescents is a major cause of unintended pregnancy and sexually transmitted infections. In order to promote condom use, it is essential to understand factors associated with condom non-use. AIM:Our aim was to evaluate sex differences and associated factors of condom non-use based on the nationally representative Brazilian National School Health Survey. METHODS:The study participants were 100,962 adolescents 13-18?years old, 9th graders from both public and private schools throughout Brazil. The following factors were considered as explanatory group variables for the outcome of condom non-use among adolescents: school and health service, sexual behavior, substance use, and self-reported body and health perception. Poisson regression model was performed. RESULTS:Of the total students, 28% (n?=?28,157) had had sexual intercourse at least once. (boys, 37.1%; girls, 19.5%). Of these, 69.2% had used condoms the last time they had intercourse (girls: 68%; boys: 69.9%). The variables associated with condom non-use for both sexes were not having accessed a health service or approached a health professional for health-related care; not having received pregnancy prevention counseling or guidance on AIDS or STI prevention at school; early sexual initiation; no additional contraception method; substance use; feeling alone; not being satisfied with their own body; feeling fat or thin; and poor self-reported health. The number of sexual partners was also associated with condom non-use; however, contrasting behavior was indicated between sexes. A higher number of sexual partners indicated less use of condoms among girls, while for boys, a higher number of sexual partners indicated higher condom use. CONCLUSION:High condom non-use appears to be associated with lack of health care access and sexual health education, poor sexual practices, substance use, and poor self-perception, indicating areas for health promotion programs.

Project description:ObjectiveTo identify the association between educational level and physical activity (PA) in specific domains according to sex, among residents of 26 Brazilian state capitals and the Federal District.MethodsThis is a cross-national survey, with data obtained from the Telephone-based Surveillance of Risk and Protective Factors for Chronic Diseases (VIGITEL), in 2017, conducted with individuals ≥ 18 years old (n = 53,034). The education level (classified as ≤ 4 years, 5 to 8 years, 9 to 11 years, and ≥ 12 years of education) and PA of participants (meeting PA recommendations and performing this active behaviour) in the commuting, domestic, leisure, and work domains were self-reported. Binary logistic regression was used to analyze the data obtained from the survey.ResultsMales and females with higher education were less likely to meet PA recommendations (males: OR = 0.68 [95% CI 0.52-0.91]; females: OR = 0.41 [0.34-0.48]) and perform the active behaviour (males: OR = 0.73 [0.57-0.93]; females: OR = 0.27 [0.23-0.32]) in the domestic domain. In the work domain, the two outcomes were associated with education only for males, indicating that those with more years of education had less chance of meeting PA recommendations (OR9 to 11 years = 0.61 [0.46-0.83]; OR≥12 years = 0.21 [0.15-0.30]) and performing it (OR9 to 11 years = 0.64 [0.49-0.84]; OR≥12 years = 0.25 [0.18-0.34]). However, more years of education seemed to positively influence meeting PA recommendations (males: OR9-11 years = 2.26 [1.79-2.87]; OR≥12 years = 2.91 [2.28-3.72]; females: OR5-8 years = 1.26 [1.04-1.54]; OR9-11 years = 1.81 [1.52-2.16]; OR≥12 years = 2.69 [2.25-3.22]) and practicing this behaviour (males: OR5-8 years = 1.29 [1.01-1.63]; OR9-11 years = 2.54 [2.04-3.17]; OR≥12 years = 3.31 [2.64-4.16]; females: OR5-8 years = 1.23 [1.03-1.46]; OR9-11 years = 1.75 [1.51-2.01]; OR≥12 years = 2.94 [2.53-3.40]) in leisure time for both sexes.ConclusionEducation level appears to be an important determinant in the relationship with PA in its different domains, especially in the leisure and domestic domains, for both sexes.

Project description:Preventing unintended pregnancy and sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) infection, among adolescents is a public health priority. This report presents prevalence estimates for condom and contraceptive use among sexually active U.S. high school students from the 2019 Youth Risk Behavior Survey. Behaviors examined included any condom use, primary contraceptive method use, and condom use with a more effective contraceptive method, all reported at last sexual intercourse. Analyses were limited to sexually active students (i.e., those who had sexual intercourse with one or more persons during the 3 months before the survey). Except for any condom use, students reporting only same-sex sexual contact were excluded from analyses. Weighted prevalence estimates were calculated, and bivariate differences in prevalence were examined by demographic characteristics (sex, race/ethnicity, and grade) and other sexual risk behaviors (age of sexual initiation, previous 3-month and lifetime number of sex partners, and substance use before last sexual intercourse). Nationwide, 27.4% of high school students reported being sexually active (n = 3,226). Among sexually active students who reported having had sexual contact with someone of the opposite sex (n = 2,698), most students (89.7%) had used a condom or a primary contraceptive method at last sexual intercourse. Prevalence of any condom use at last sexual intercourse was 54.3%, and condoms were the most prevalent primary contraceptive method (43.9% versus 23.3% for birth control pills; 4.8% for intrauterine device [IUD] or implant; and 3.3% for shot, patch, or ring). Approximately 9% had used condoms with an IUD, implant, shot, patch, ring, or birth control pills. Using no pregnancy prevention method was more common among non-Hispanic black (23.2%) and Hispanic (12.8%) students compared with non-Hispanic white students (6.8%); compared with Hispanic students, using no pregnancy prevention method was more common among non-Hispanic black students. Prevalence of condom use was consistently lower among students with other sexual risk behaviors. Results underscore the need for public health professionals to provide quality sexual and reproductive health education and clinical services for preventing unintended pregnancy and STDs/HIV and decreasing disparities among sexually active youths.

Project description:Compared to the general population, men who have sex with men (MSM) are at greater risk for HIV and less understood due to their more hidden and stigmatized nature. Moreover, the discrepancy in findings in the literature merits further investigations in MSM populations from different cultures and settings. We therefore conducted this study to explore factors associated with inconsistent condom use among high-risk MSM in Cambodia.This cross-sectional study was conducted in 2014 among 367 MSM randomly selected from Battembang and Siem Reap using a two-stage cluster sampling method. A structured questionnaire was used for face-to-face interviews to collect information on characteristics of respondents, HIV testing history, self-perception of HIV risk, substance use, sexual behaviors, mental disorders, and HIV knowledge. Multivariable logistic regression analysis was performed to identify factors independently associated with inconsistent condom use.On average, 62.3% of respondents reported that they always used condoms over the past three months. The rates varied with types of sexual partners; the proportion of respondents who reported always using condoms was 55.1%, 64.2%, 75.9%, 73.0%, 78.1%, and 70.3%, for sexual partners who were girlfriends, boyfriends, female sex workers, male sex workers, female clients, or male clients, respectively. After adjustment, inconsistent condom use was significantly associated with age of ≥25 (AOR = 1.77, 95% CI = 1.09-2.86), self-rated quality of life as good or very good (AOR = 4.37, 95% CI = 1.79-5.67), self-perception of higher HIV risk compared to the general population (AOR = 2.37, 95% CI = 1.35-4.17), illicit drug use in the past three months (AOR = 5.76, 95% CI = 1.65-10.09), and reported consistent lubricant use when selling anal sex to men in the past three months (AOR = 2.85, 95% CI = 1.07-8.12).We found risky sexual behaviors to be considerably high among MSM in this study, especially among those who used illicit drugs or were older than 25. HIV education and social marketing should be expanded and specifically designed for MSM to better educate on the increased risk of HIV with unprotected anal sex and illicit drug use as risk factors, and the importance of the use of both condoms and lubricant during anal intercourse.
