Prevalence and correlates of early sexual initiation among Brazilian adolescents

Background Early adolescence is a critical stage in adolescents. This is the phase at which many young people start their sexual life early, increasing the risk of sexually transmitted infections and unintended pregnancy. Few studies have analyzed the factors associated with early sexual initiation in very young adolescents in low- and middle-income countries. Therefore, this study assessed the early sexual initiation stratified by sex and its correlates in a sample of Brazilian adolescents. Methods The study sample included Brazilian adolescents aged 12–14 who participated in The Study of Cardiovascular Risk in Adolescents (ERICA), a multicenter, school-based, country-wide, cross-sectional study. Early sexual initiation was defined as the first sexual intercourse at or before 14 years old. Multivariate logistic regression was used to identify independent factors associated with early sexual initiation. Results The prevalence of early sexual initiation was 7% among girls and 18% in boys. In a multivariate analysis, the adolescent’s age, mother’s schooling, smoking, alcohol consumption, and Tanner Stages were associated with early sexual initiation for both boys and girls. For girls, living with both parents, common mental disorders, and age at menarche were predictors of early sexual initiation, while race and type of school were correlated to early sexual initiation only for boys. Conclusions The early sexual initiation was associated with sociodemographic, lifestyle risk factors and secondary sexual characteristics in both sexes, while there were differences between the predictors of early sexual initiation among girls and boys. It emphasizes the importance of sex education and promotes healthy lifestyles in environments through families and schools in early adolescence.

Early Sexual Debut among Ghanaian Women: Correlates and Psychological Effect

Early sexual initiation is linked to an increased risk of HIV/AIDS and other STIs among teenagers, as well as having multiple partners, not using contraception, unintended pregnancy, and illegal abortions. Aim. To identify the correlates and psychological effects of early sexual debut among not-in-union women in Ghana. A descriptive cross-sectional survey was used for this study using data from Ghana Multiple Indicator Cluster Survey (MICS) for the year 2017/2018. SPSS software was used for data analysis, bivariate analysis for association was done using chi-square, and the prediction was done using a binary logistic regression model. The national prevalence of nonmarital early sexual initiation this current study recorded was 56.9%. Predictors variables were age, 15-24/≥35 years ( AOR = 1.51 , 1.28-1.78), ever educated ( AOR = 0.50 , 0.43-0.60), urban address ( AOR = 0.85 , 0.74-0.98), married/single ( AOR = 1.23 , 1.07-1.42), cohabitation/single ( AOR = 1.43 , 1.19-1.72), Greater Accra Region/Upper West Region ( AOR = 0.67 , 0.49-0.92), and health insurance ( AOR = 0.89 , 0.79-0.998). As the wealth indices of the woman decrease from the richest to poorest, the likelihood of early sexual debut inversely increases: fourth/richest ( AOR = 1.23 , 1.04-1.45), middle/richest ( AOR = 1.31 , 1.09-1.58), second/richest ( AOR = 1.38 , 1.11-1.72), and poorest/richest ( AOR = 1.44 , 1.12-1.86); use of the internet ( AOR = 0.58 , 0.50-068); substance use and alcohol ever use ( AOR = 1.32 , 1.17-1.49); cigarette ever use ( AOR = 2.58 , 1.44-4.64); contraceptive use ( AOR = 1.31 , 1.16-1.49); and ever heard of HIV ( AOR = 59 , 0.42-0.82). In conclusion, the prevalence of early sexual debut is still high in Ghana, especially among the northern regions. Several factors predicted early sex debut, and low life satisfaction and happiness were related to early sexual debut.

Birth Order and First Sexual Experience: Do Siblings Influence Sexual Debut in Adolescents?

Birth order may foster specific roles for individuals within the family and set in train a dynamic that influences the development of specific behaviors. In this paper, we explored the relationship between birth order, sex, timing of sexual initiation, and its consequences for risky sexual behavior and sexual health. We conducted a path analysis to simultaneously estimate direct and indirect effects using data from the National Survey of Sexual Attitudes and Lifestyles (NATSAL-3). Whereas women born as only-children were more likely to sexually debut at later ages, middle-child boys were significantly more prone to initiate sexual intercourse earlier compared with first-borns. As expected, early sexual initiation was associated with riskier behaviors and sexual health outcomes. These associations were partially moderated by siblings role as confidants about sexuality. Our findings have implications for preventive programs aimed at promoting healthy sexual debuts and behaviors over the life span.

Sexual Abuse and Sexually-Transmitted HIV/AIDS in Jamaican Children and Adolescents Aged 6-19 Years

Introduction: Risk factors and outcomes of sexually-acquired human immunodeficiency virus infection were characterized in Jamaican children and adolescents. Methodology: Management was carried out by multidisciplinary teams in Infectious Diseases clinics during August 2003 through February 2019 using modified World Health Organization HIV criteria. Results: There were 78 clients, aged 6 to 19 years, with females:males = 4:1 (p < 0.05). Sexual-initiation occurred in 60%, 47 before < 16 years (median 13 years, with four < 10 years; females:males = 7:1). Sexual-initiation preceded HIV diagnosis in all cases (median 2 years). Secondary education 93% (69/77) and living with non-parental relatives 17% (13/78) were associated with early sexual-initiation (p < 0.042); as was later imprisonment in 6% (3/52). Other sexually transmitted infections 36% (19/53) were associated with sexual-initiation ≥ 16 years (p < 0.01). Risks for ongoing HIV-transmission included infrequent condom use 74% (39/53), body-piercings 50% (24/48), illicit drug use 37% (28/76), tattoos 36% (19/52), transactional sex 14% (7/53) and pregnancy 56% of girls. 77% (59/77) had Centres for Diseases Control’s Category A HIV infection; 82% (61/75) initiated anti-retroviral therapy; 75% (56/75) had first-line drugs, with helper T lymphocyte counts ≥ 500 cells/μL in 61% (48/78) and HIV viral load of < 1,000 copies/μL in 63% (40/64). Complications included dermatological 39% (20/52), respiratory 25% (13/52) and neurological 15% (8/52). Early sexual initiation was associated with depression 43% (33/76; p < 0.004) and suicidal attempt or ideation 23% (18/77; p < 0.096). Four (5%) died. Conclusions: Sexually transmitted HIV/AIDS in children and adolescents should preempt prompt medical, legal and psychosocial interventions.

Rigorous evaluation of a substance use and teen pregnancy prevention program for American Indian girls and their female caregivers: a study protocol for a randomized controlled trial

Background Early sexual initiation is associated with higher risk for sexually transmitted infection, teen pregnancy, domestic violence and substance use in later adolescence and early adulthood. Native American adolescents are more likely to have early sexual initiation compared to other racial/ethnic groups. Few programs designed with and for Native adolescents to delay sexual initiation and substance use have been tested through rigorous evaluations. This is the protocol for the randomized controlled trial of the Asdzáán Be’eena’ program, a teen pregnancy and substance use prevention program for young Native girls and their female caregivers. Methods N = 410 female adolescents ages 10–14 and their female caregivers will be enrolled in the study and randomized to the intervention or control arm. The intervention consists of the 11-session Asdzáán Be’eena’ program. The control arm consists of mailed non-monetary incentives. All participants will complete evaluations at baseline and 3 follow-up timepoints (immediate, 6 and 12 months post intervention). Evaluations include measures to assess protective factors associated with delayed sexual initiation and substance use. Discussion This is one of the first rigorous evaluations of a gender-specific, culturally tailored teen pregnancy and substance use primary prevention program for Native girls and their female caregivers. If proven efficacious, Native communities will have a culturally appropriate program for promoting protective factors associated with delayed substance use and sexual risk taking. Trial registration NCT04863729; April 27, 2021.

Prevalence and Factors Associated with Early Sexual Initiation among College Students in Southwest Ethiopia

Background. Early age at first sexual practice is a public health issue and now common around the world especially in the developing countries. The development of effective strategies to reduce the adverse consequences of early sexual initiation becomes real when sufficient data is available. Therefore, this study is aimed at assessing the prevalence and factors associated to early sexual initiation among college students in southwest Ethiopia. Methods. A cross-sectional study was conducted among 453 college students in southwest Ethiopia from April to May 2018. A two-stage stratified sampling technique was used to select the study participants. The data were collected using structured pretested self-administered questionnaire. The collected data were entered using Epi-Data version 4.2.0.0 and analyzed using SPSS version 20. Logistic regression models were fitted to assess the effect of independent variables on the outcome variable. Significance was declared at p < 0.05 in the multivariable logistic regression analysis. Results. The proportion of early sexual initiation among college students was 17.9%, 95% CI (14.4%-24.4%). The mean age of sexual intercourse was 17.6 (±2 SD) years. Nearly three-fourths (73.4%) of the respondent’s reason for early sexual intercourse was falling in love. More than half (62.2%) of the respondents used a condom for their first sexual intercourse. The factors associated with early sexual initiation were being female ( AOR = 2.09 and 95% CI [1.17-2.35]), chewing khat ( AOR = 7.05 and 95% CI [3.81-13.1]), exposed to pornographic materials at age < 18 years ( AOR = 3.57 and 95% CI [1.94-6.89]), and poor knowledge of sexually transmitted diseases ( AOR = 8.69 and 95% CI [3.52-21.5]). Conclusion. The prevalence of early sexual initiation among college students was alarmingly high. This may be associated with a huge burden of poor sexual and reproductive health. Therefore, creating awareness of the factors and related negative sexual and reproductive health effect of early sexual initiation for young peoples through the use of mass media (television and radio), school teachers, and parents plays a paramount importance.

Early sexual initiation and risky sexual practices among alcohol- and tobacco-using young adults in Taiwan: mediation analysis of preceding-sex use of illicit drugs

Background As early sexual initiation is increasingly common in East Asia, we examined its relations to risky sexual practices in alcohol- and tobacco-using individuals in Taiwan and evaluated whether the associations were mediated through preceding-sex use of illicit drugs. Methods Participants, recruited from alcohol- and tobacco-using adults aged 18 to 50 in Taipei through respondent-driven sampling (N = 1115), completed a computer-assisted self-interview covering questions on substance use and sexual experiences. In a subsample of 916 participants who had had sexual experience (median age 27), we examined the relations of early sexual initiation (< 16 years) to multiple sexual partners, casual sex, group sex, and rare condom use. Causal mediation analyses were conducted to examine whether illicit drug use preceding sex mediated these associations. Results Around 9.3% reported early sexual initiation and the prevalence of risky sexual practices ranged from 7% (group sex) to 47% (rare condom use). Early initiators had a higher prevalence of regular binge drinking, illicit drug use, and risky sexual practices. In the multivariable analyses, higher odds of multiple sexual partners, casual sex, and group sex were consistently associated with early sexual initiation, gender, and their interaction. Mediation through preceding-sex use of illicit drugs was found between early sexual initiation and the three risky sexual practices, with the proportions mediated ranging from 17 to 19%. Conclusions Early sexual initiators were more likely to engage in risky sexual practices and preceding-sex use of illicit drugs partially explained this relationship, calling for more attention to this population’s sexual health.

Determinants of early sexual initiation among female youth in Ethiopia: a multilevel analysis of 2016 Ethiopian Demographic and Health Survey

Background Evidences on determinants of early sexual initiation among female youth is still limited especially; community-level factors are not investigated in Ethiopia. Therefore, the aim of this study was to assess individual and community-level factors associated with early sexual initiation among female youth in Ethiopia. Methods The 2016 Ethiopian Demographic and Health Survey (EDHS) dataset were used and a total of 6143 participants (female youth) were included. Multi-level mixed-effect logistic regression was done to identify individual and community-level factors. Adjusted odds ratio along with 95% confidence interval was used to show the strength and direction of the association. Finally, the level of statistical significance was declared at P value less than 0.05. Results Individual-level factors significantly associated with early sexual initiation among female youth were; age group from 19 to 24 years [AOR = 5.8, 95% CI = (4.6, 7.3)], not attending school [AOR = 14.1, 95% CI = (8.1, 24.7)], ever chewing Chat [AOR = 2.0, 95% CI = (1.3, 3.0)]. From community-level factors: living in Addis Ababa [AOR = 0.3, 95% CI = (0.2, 0.5)], living in Gambella [AOR = 2.7, 95% CI = (1.7, 4.3)] and live in a low proportion of poor communities [AOR = 0.7, 95% CI = (0.5, 0.9)] were significantly associated with early sexual initiation among female youth in Ethiopia. Conclusions Age, low educational status, ever chewing Chat, region and live in a high proportion of poor community had a statistical association with early sexual initiation among female youth in Ethiopia. Improving educational coverage and community-level of wealth status are important intervention areas to delay the age of early sexual initiation.
