Socio-Environmental and Behavioral Correlates of Having Ever Had Sexual Intercourse Among Adolescents in Peru: A School-Based Cross-Sectional Study

Objective: We assessed the socio-environmental and behavioral correlates of having ever had sexual intercourse among Peruvian adolescents aged 12–18 years in Lima. Methods: A cross-sectional study was conducted in 2014. Result: Of 950 participants, 26.5% of males and 13.0% of females had ever had sexual intercourse. Early adolescents who ever had sexual intercourse had higher odds of being insulted, being involved in a fight, and smoking; whereas late adolescents having sexual experiences were more likely to be male and to report smoking, alcohol consumption, involvment in a fight, and having no/low parental understanding. Conclusion: An integrated approach is useful in addressing risk behaviors in adolescents.     

Abstinence and Birth Control Among Rural Adolescents in Impoverished Families: A Test of Theoretical Discriminators

This was a study of 357 adolescents who resided with AFDC families in ten rural counties in Arkansas. The study examined predictors of birth control from sociodemographic variables, control, strain and differential association theories. This was the first theoretically-based investigation of abstinence and birth control among adolescents living with families on welfare in impoverished rural communities. Bivariate analyses indicated that all of the study factors, with the marginal exception of attachment to father, showed significance variance between the three groups of adolescents who had not had sexual intercourse, those who always used birth control, and those who did not always use birth control. The first function of the discriminant analysis discriminated between youth who had not had sexual intercourse and those who were sexually active, and indicated that the former (in order of discrimination) were younger, had fewer sexually active friends or family members, were more religious, had more fear of giving birth if sexually active, and had stronger beliefs in the moral validity of societal laws and norms. The second function discriminated between those who always used birth control and youth who did not always use birth control. The significant discriminators (in order of discrimination) showed that adolescents who always used birth control attended church more often, were more likely to be persons of color than Caucasian, had closer attachments to their mothers, and presently did not desire a baby to love. Social work implications of these findings are discussed from an ecological perspective.     

Physical Abuse in Early Childhood and Transition to First Sexual Intercourse among Youth in Cape Town,South Africa

This study examined the relationship of physical abuse in early childhood and timing of first sexual intercourse among young South Africans aged 14 to 22 in Cape Town. Using the Cape Area Panel Survey and applying log-normal models, time ratios were estimated to show how rapidly or slowly youth experience first sexual intercourse. Results indicated that boys who experienced physical abuse in early childhood had faster timing to first sex. Boys and girls with violent school environments had faster timing to first sex. Race moderated the effects of physical abuse. Compared to Blacks, Coloreds who experienced higher levels of physical abuse in early childhood had faster timing to first sex. Youth with greater knowledge about HIV/AIDS and those with greater risk perception of contracting HIV/AIDS delayed first sex. On the basis of these findings, policy makers are encouraged to consider the early childhood experiences of youth when designing policies toward HIV/AIDS prevention in South Africa.     

Looking back: the experience of first sexual intercourse and current sexual adjustment in young heterosexual adults

A young person's first consensual sexual intercourse experience is often a remarkable and memorable experience. However, little systematic information exists regarding contextual factors of first intercourse, the affective salience of the experience, possible effects on sexual attitudes and beliefs, and subsequent sexual development and adjustment. This retrospective study aimed to examine these in a sample of 475 young adults. Overall, young men and women experienced intercourse for the first time around age 17, were in a committed relationship, and reported positive affective responses. Affective reactions to the first sexual intercourse experience, sexual self-efficacy, sexual aversion, and age at first intercourse affected individuals' current sexual adjustment; however, only sexual self-efficacy mediated between first intercourse and current sexual adjustment in young men and women. Older age at first intercourse was associated with less sexual self-efficacy and lower current sexual adjustment for women. This study provides initial data to suggest that the first sexual intercourse experience significantly impacts current sexual adjustment by affecting beliefs about sexual self-efficacy.

The Role of Religiousness and Gender in Sexuality Among Mexican Adolescents

This study examined the role of religiousness and gender in age at first intercourse, and sexual expectations and values in Mexico, a macrocontext where the majority is Mexican and Catholic (83%). Participants were Catholic and nonreligious adolescents (54% girls) attending middle (71%) or high school. Findings indicated that Catholic adolescents engaged in sexual intercourse at later ages than nonreligious adolescents. Both religious attendance and importance of religion and values in sexual decision making were associated with more conservative sexual values. Boys who were raised Catholic were more likely to endorse female virginity values and were less likely to expect to wait to have sex until married than nonreligious boys. These associations were not significant among girls. Catholic boys may be more likely to internalize sexual double standard beliefs regarding premarital sex than nonreligious boys. This study expands our understanding of the role of religiousness in Mexican adolescents’ sexuality.     

Retrospective Paternal and Maternal Parenting Styles,Regulatory Self-Efficacy and Adolescent Risk Taking

This study aims to calculate a scaled risk-taking behavior index and to test a model in which maternal and paternal parenting styles affect risk-taking behavior with a mediation of adolescents’ regulatory self-efficacy. Participants were 816 adolescents (44% males) responding to a self-report questionnaire about their risk-taking behavior, regulatory self-efficacy, and retrospective memories of paternal and maternal parenting styles. Results suggested an item rating in the index showing that behaviors considered less risky referred to alcohol use and the unplanned first sexual intercourse, whereas behaviors considered more risky referred to the lack of use of contraceptives and the age of the first sexual intercourse. Results revealed a significant indirect effect of authoritative and authoritarian styles on risk-taking behavior. These styles shaped the adolescents’ regulatory self-efficacy, which in turn predicted adolescent risk-taking behavior. Results underline the complex interplay of relationships between parents and their children.     

Investigating the Timing of First Sexual Intercourse Among Youth in EDO State,Nigeria in the Context of the Aids Epidemic

ABSTRACT

Objectives: This study examined the timing of sexual debut among youth in Edo state, Nigeria given the role that sexual abstinence plays in HIV prevention in sub-Saharan Africa. Methods: Survey data were collected from rural youth aged 11 to 17 years old enrolled in Junior Secondary Schools in Edo State, Nigeria. Discrete-time hazard techniques were used to examine the effects of theoretically relevant covariates on the timing of sexual debut among youth in Edo State. Results: Results indicate strong, significant relationships between psychosocial predictors and age at first sex for boys and girls. Youth with higher levels of knowledge about HIV as well as those who rejected common myths about HIV transmission delayed first sexual intercourse. Early sexual intercourse was strongly associated with experiencing pressure to engage in sex, while delay was associated with greater confidence that one could decline to participate in sex. On the other hand, youth with higher condom use self-efficacy engaged in first sexual intercourse at an earlier age. Conclusions: These results support the relevance of programs such as Nigeria's Family Life and HIV Education to contribute to delaying sexual intercourse focusing precisely on the forms of knowledge, myth rejection, motivation, and behavioral self-efficacy measured here. They provide policymakers with concrete evidence to increase support for such programming as a means to combat the spread of HIV among youth.     

The amount and timing of parent‐adolescent sexual communication as predictors of late adolescent sexual risk‐taking behaviors

This study examined the moderating role of timing of first discussion of sexual intercourse with mothers and fathers on the relationship between the amount of sexual communication and sexual risk‐taking behaviors in late adolescence. Late adolescents (N = 214) completed questionnaire measures regarding the amount and timing of sexual communication with their mothers and fathers. In addition, the participants provided information about their various sexual risk‐taking behaviors. In general, the results suggest that timing of first discussion of sexual intercourse contributes additional variance in several sexually risky behaviors beyond that contributed by the amount of communication with both fathers and mothers. The implications of these findings are discussed.     

“Dude,I’m Seventeen … It’s Okay Not to Have Sex by This Age”: Feelings,Reasons, Pressures,and Intentions Reported by Adolescents Who Have Not Had Sexual Intercourse

This study investigated feelings, reasons, pressures, and previous sexual experiences reported by students who have not had sexual intercourse and how these factors are associated with self-rated likelihood of having sex during the next year. Using data from the Fifth National Survey of Australian Secondary Students and Sexual Health (n = 783), this study found, in general, students had positive feelings about not having sex. Reasons for not having sex such as being proud to say no and not being ready were rated higher in importance than fear of potential outcomes or religious/cultural beliefs. Students reported limited pressure from parents and friends and, despite not having sexual intercourse, more than half of the sample had experienced some form of sexual activity. Stronger likelihoods of having sex during the next year were reported by students who had previously engaged in other sexual practices, reported more pressure from friends to have sex, and had negative feelings about not having sex. Sexuality educators can use these findings to guide approaches to sex education, emphasizing feelings, intentions, and reasoning over fear tactics. Discussion of a range of sexual practices will address more closely the experiences of young students as they begin their sexual lives.     

The amount and timing of parent-adolescent sexual communication as predictors of late adolescent sexual risk-taking behaviors

The present study examined the moderating role of timing of first discussion of sexual intercourse with mothers and fathers on the relationship between the amount of sexual communication and sexual risk-taking behaviors in late adolescence. Late adolescents (N = 214) completed questionnaire measures regarding the amount and timing of sexual communication with their mothers and fathers. In addition, the participants provided information about their various sexual risk-taking behaviors. In general, the results suggest that timing of first discussion of sexual intercourse contributes additional variance in several sexually risky behaviors beyond that contributed by the amount of communication with both fathers and mothers. The implications of these findings are discussed.     

READING, WRITING, AND SEX: THE EFFECT OF LOSING VIRGINITY ON ACADEMIC PERFORMANCE

Controlling for a wide set of individual- and family-level observables available in the National Longitudinal Study of Adolescent Health, ordinary least squares (OLS) estimates show that sexually active adolescents have grade point averages that are approximately 0.2 points lower than virgins. However, when information on the timing of intercourse decisions is exploited and individual fixed effects are included, the negative effect of sexual intercourse disappears for females, but persists for males. Taken together, the results of this study suggest that while there may be adverse academic spillovers from engaging in intercourse for some adolescents, previous studies' estimates are overstated due to unmeasured heterogeneity.

Family influences on adolescent sexual and contraceptive behavior

Studies of adolescent pregnancy risk are relevant to understanding responsible adolescent sexual behavior because most investigators have focused on the key proximal determinants of pregnancy--sexual intercourse and contraceptive use--rather than analyzing pregnancy status per se. Lesser pregnancy risk is associated with teens remaining sexually abstinent, postponing onset of intercourse, and having intercourse less often or with fewer partners, as well as by using contraception at first or most recent intercourse and by using contraception consistently over time. Living with a single parent, in a lower SES family, having older sexually active siblings or pregnant/parenting teenage sisters, being a victim of sexual abuse, and residing in disorganized/dangerous neighborhoods all place teens at elevated risk of adolescent pregnancy. Parent-child closeness or connectedness, and parental supervision or regulation of children, in combination with parents values against teen intercourse (or unprotected intercourse), decrease the risk of adolescent pregnancy. Studies about parent-child sexual communication and adolescent pregnancy risk are less conclusive, largely because of methodological complexities.     

Early Age of First Sexual Intercourse and Depressive Symptomatology among Adolescents

Past literature has provided conflicting evidence for the association between adolescent sexual intercourse and depressive symptomatology. Whereas some studies conclude that sexually active youth may be at risk for depression, others provide contrary results. Thus, it is unclear as to whether depression results directly from coitus or if this relationship is explained by other factors—that is, there may be biological, psychological, or sociological predictors of both depressive symptomatology and early sexual intercourse. Using the National Longitudinal Study of Adolescent Health dataset, depressive symptomatology in adolescents over a seven-year time period was analyzed. The final sample (n = 6,510) was comprised of 49.35% male (n = 3,213) and 50.65% female (n = 3,297) participants. Although an earlier age of first coitus was predictive of future depressive symptoms, both variables appear to be concomitant outcomes of the biopsychosocial process. Thus, although one may be able to use early coitus as a marker for subsequent depressive symptomatology, it does not appear to occur because of early sexual intercourse. Furthermore, the reverse relationship was not found to be significant in this study—that is, higher levels of previous depressive symptomatology did not predict an earlier age of first sexual intercourse in adolescents.     

Barrier versus oral contraceptive use: a study of female college students

Although they provide birth control and are easier to use, oral contraceptives (OCPs) are not the preferred approach to preventing sexually transmitted disease (STD). Do the knowledge, attitudes, and experiences of oral contraceptive users place them at greater risk for STDs than those who employ barrier methods? This study examined differences between sexually active female college students (ie, those who reported ever having had vaginal intercourse) who used OCPs and those who employed barrier methods of contraception at the time of their most recent intercourse. The authors analyzed HIV- and other STD-related knowledge, attitudes, and behaviors from three consecutive annual health surveys of young women about to begin their first year of college. Findings showed barrier and OCP users to be comparable in knowledge about the effectiveness of various contraceptive methods in protecting them against STDs, perceived personal susceptibility to HIV, and experiences with alcohol before sexual intercourse. Oral contraceptive users, compared with those in the group who used barrier methods, reported a greater number of recent partners (p less than .03) and greater perceived vulnerability to STDs (p less than .03). Student healthcare providers must develop creative educational strategies to encourage simultaneous use of both oral contraceptives and barrier methods to protect students against STDs and pregnancy.     

Socialization Influences on Early Adolescents' Cognitive Susceptibility and Transition to Sexual Intercourse

This study examined the relationship between perceived socialization from parents, school, peers, and media and adolescents' cognitive susceptibility to initiating sexual intercourse and transition to intercourse 2 years later. Baseline and follow‐up in‐home Audio‐Computer Assisted Self Interview surveys were completed by 854 Black and White male and female adolescents who, at baseline, were 12–14 years old and had not engaged in sexual intercourse. Results showed that stronger connections to parents and schools and less exposure to permissive sexual norms from peers and media were associated with less susceptibility and sexual behavior, especially among White adolescents. Susceptibility mediated 38–64% of the relations between parent and school socialization and sexual intercourse behavior, and mediated 28–53% of the peer and media socialization links to behavior. Findings provide support for social cognitive models of adolescents' behavior and suggest potential strategies for successful interventions to delay initiation of sexual intercourse.     

Educational Differences in Adolescents' Sexual Health: A Pervasive Phenomenon in a National Dutch Sample

Educational level is strongly associated with age of first intercourse and risk of unintended pregnancies. This study examined these associations in a large representative sample of Dutch adolescents and also included associations of educational level with other sexual health aspects. Adolescents aged 12 to 25 (3,926 boys and 3,915 girls) completed an online questionnaire that included measures of romantic and sexual experience; the evaluation of their sexual debut; the risk of sexually transmitted infections (STIs) and pregnancy; and sexual attitudes, satisfaction, self-efficacy, knowledge, victimization, and functioning. The results showed that adolescents on a vocational track or who completed fewer years of education were more at risk of several adverse sexual health outcomes than adolescents on an academic track. They had their first sexual experiences at an earlier age; evaluated these experiences less favorably; had less sexual health knowledge and fewer refusal skills; and had a higher risk of unintended pregnancy, STIs, and victimization. Possible explanations for these consistent differences are discussed. Sex education and services should pay specific and targeted attention to less educated young people and tailor their efforts specifically to the needs, characteristics, and realities of this group.     

Child Support Enforcement and Sexual Activity of Male Adolescents

Strong child support enforcement requires fathers to take financial responsibility for their children and may also encourage more responsible sexual behavior. Using the 1997 – 2001 waves of the 1997 National Longitudinal Survey of Youth (N = 4,272), this article examines the association between child support enforcement and the sexual activity of male adolescents. Stronger child support enforcement was associated with fewer sexual partners, less frequent sexual intercourse, and a higher likelihood of using contraceptive methods among adolescents who had had sexual intercourse in the 12 months preceding data collection. The effects of child support enforcement were particularly strong for non‐White adolescents and those living in high‐poverty areas. These findings suggest that strengthening child support enforcement may be associated with reductions in some aspects of male adolescents’ sexual activity.     

Sexual Experimentation in Heterosexual,Bisexual, Lesbian/Gay,and Questioning Adolescents From Ages 11 to 15

To examine adolescent sexuality development, we analyzed data from a British cohort study (N = 5,070), which assessed the same 12–14 sexual activities at ages 11, 12, 13, and 15, and sexual orientation identity at age 15. The sexual activities ranged from low (e.g., cuddling), moderate (e.g., kissing), to high (e.g., sexual intercourse) intensity. We found that most adolescents having sexual activities of low‐to‐moderate intensity with same‐sex individuals also had them with other‐sex individuals, and adolescents having other‐sex contacts of low intensity often reported them nonexclusively. Furthermore, other‐sex and same‐sex sexual activities did not reliably distinguish between sexual orientation identities. Sex differences in these phenomena were absent or small. These findings suggest that many adolescents have low‐intensity nonexclusive sexual behaviors.     

Adaptive training for existing male transsexual gender role: A case history

The development of AIDS interventions for adolescents is hindered by the lack of data on the conditions that influence high‐risk sexual behavior. We examined psychosocial correlates of condom use and multiple partner sex for a sample of sexually‐active heterosexual adolescent women. Respondents reported higher levels of vaginal intercourse than the “average” adolescent. A minority were engaging in anal intercourse. Condom use was associated with perceived enjoyment of condoms and communication skills. Number of sexual partners was associated with susceptibility beliefs, social norms, and sexual communication skills. The findings support the general observation that AIDS interventions with adolescents should build sexual communication skills, address motivational issues, and teach people how to enjoy safe‐sex activities.
