The influence of puberty, family processes, and leisure activities on the timing of first sexual experience

Higher parental socioeconomic status accelerates sexual debut: Evidence from university students in Italy

In this paper we analyze how the timing and type (protected or unprotected) of sexual debut are influenced by parental socioeconomic status (SES). We argue that depending on whether a "parental control" or a "cultural openness" mechanism prevails, one could find a postponing or an anticipating effect of higher parental SES on children's timing of sexual debut. By applying event-history techniques to unique data from the two releases of the Sexual and Emotional Life of Youths survey (2000 and 2017), we found a clear accelerating effect of higher parental SES-parental education and father's social class-on the sexual debut of Italian university students. The effect is partly mediated by family characteristics related to the cultural openness mechanism, such as low parental religiosity, greater communication about sex, and parental permissiveness; on the contrary, we only found weak support for the parental control explanation. Higher parental education is associated with a higher likelihood of protected first sexual intercourse-and especially of condom use-even if more precocious. Our results dispute the North American- and Anglo-Saxon-driven finding that high-SES children postpone their sexual debut.

Sexual Experiences and Perspectives of Adolescents and Young Adults With Intellectual and Developmental Disabilities

The purpose of this study is to understand the sexual experiences and perspectives of adolescents and young adults (AYA) with intellectual or developmental disabilities, how they are receiving sexual education, and how sexual education can be tailored to their needs. This qualitative study utilized semi-structured focus groups and interviews with eight AYA with intellectual or developmental disabilities from January 14 to May 7, 2019. Data were analyzed using a constant comparative approach. Participants reported a diverse range of sexual experiences and an interest in marriage and parenting in the future. Two themes emerged for how AYA are learning about sexual health information: through formal (school, doctors’ visits, or from caregivers) and informal education (peers, siblings, self-exploration, or Pop Culture). Sexual education can be tailored to this population by addressing educational gaps (pregnancy, contraception, sexually transmitted infections, intimacy, and sexual activity) and by implementing specific participant recommendations (proactive, inclusive education with real-life examples). With a growing emphasis on disability rights to sexual education among individuals with intellectual or developmental disabilities, it is vital to understand AYA’s experiences, perspectives, and current understanding of sexual health information so that we can design a program specifically tailored to meet their unique needs.

The Effects of Pubertal Timing and School Transition on Preadolescents' Well-Being

Previous research has indicated that pubertal development and the transition from middle or elementary school to junior high may present problems for some preadolescents. The effects of these transitions on achievement, psychological well-being, and social relations were examined using data from the National Longitudinal Survey of Children and Youth. Children were tracked during a 2-year period and the changes in outcome scores were assessed. Results indicate that psychological well-being was closely related to social relations, and socioeconomic status was predictive of achievement and social relations. However, pubertal development and school transition had a minimal impact on outcome.

Father Knows Best: Paternal Presence and Sexual Debut in African-American Adolescents Living in Poverty

Adolescents found within single-parent families without a residential father have reported higher levels of sexual debut and higher levels of reported pregnancy. Using data from the Mobile Youth Survey, the purpose of this study is to determine the impact of the presence of a father figure on the sexual debut of African-American adolescents living in poverty and to determine if gender moderates the relationship between the presence of a father figure and sexual debut. Additionally, this study will examine the family processes in which the presence of a father figure can affect the sexual debut of African-American adolescents who live within economically and socially disadvantaged communities. The results revealed that African-American adolescents reporting a father figure had lower rates of sexual debut than those youth reporting no father figure. Gender was not found to be a significant moderator in the relationship between father figure presence and sexual debut. However, existing curfews and family rules did account for some of the effects of presence of a father figure and sexual debut. The results suggest that when adolescents have a father figure in their lives, it may reduce the possibility of early sexual debut.

Beyond simple models of self-control to circuit-based accounts of adolescent behavior

Adolescence is the transition from childhood to adulthood that begins around the onset of puberty and ends with relative independence from the parent. This developmental period is one when an individual is probably stronger, of higher reasoning capacity, and more resistant to disease than ever before, yet when mortality rates increase by 200%. These untimely deaths are not due to disease but to preventable deaths associated with adolescents putting themselves in harm's way (e.g., accidental fatalities). We present evidence that these alarming health statistics are in part due to diminished self-control--the ability to inhibit inappropriate desires, emotions, and actions in favor of appropriate ones. Findings of adolescent-specific changes in self-control and underlying brain circuitry are considered in terms of how evolutionarily based biological constraints and experiences shape the brain to adapt to the unique intellectual, physical, sexual, and social challenges of adolescence.

Adjusting behavior to changing environmental demands with development

Plasticity refers to changes in the brain that enable an organism to adapt its behavior in the face of changing environmental demands. The evolutionary role of plasticity is to provide the cognitive flexibility to learn from experiences, to monitor the world based on learned predictions, and adjust actions when these predictions are violated. Both progressive (myelination) and regressive (synaptic pruning) brain changes support this type of adaptation. Experience-driven changes in neural connections underlie the ability to learn and update thoughts and behaviors throughout life. Many cognitive and behavioral indices exhibit nonlinear life-span trajectories, suggesting the existence of specific sensitive developmental periods of heightened plasticity. We propose that age-related differences in learning capabilities and behavioral performance reflect the distinct maturational timetable of subcortical learning systems and modulatory prefrontal regions. We focus specifically on the developmental transition of adolescence, during which individuals experience difficulty flexibly adjusting their behavior when confronted with unexpected and emotionally salient events. In this article, we review the findings illustrating this phenomenon and how they vary by individual.

The Later, the Better? Early, Average, and Late Timing of Sexual Experiences in Adolescence and Psychosocial Adjustment in Young Adulthood

The present article challenges the assumption that later timing of sexual experiences is unequivocally associated with higher psychosocial adjustment. Data from two representative cross-sectional German studies conducted in 1996 and 2005 were analyzed to examine the psychosocial adjustment of young adults (age 20–29) who had their first sexual experiences early (before age 16), at an average age (between age 16 and 18), or late (later than age 18 or not yet). Early timing of sexual experiences was associated with lower educational attainment. Late timing of sexual experiences was associated with poorer social relations. Early and late timing of sexual experiences were associated with lower subjective well-being. Results were replicated across the two studies and controlled for sociodemographic characteristics and (in Study 1) early adversities, parental involvement, and pubertal timing. These findings show that not only early but also late timing of first sexual experiences can be associated with lower psychosocial adjustment in selected domains in young adulthood. Further research is needed to understand maladaptive correlates of late sexual timing.

Maternal programming of reproductive function and behavior in the female rat

Parental investment can be used as a forecast for the environmental conditions in which offspring will develop to adulthood. In the rat, maternal behavior is transmitted to the next generation through epigenetic modifications such as methylation and histone acetylation, resulting in variations in estrogen receptor alpha expression. Natural variations in maternal care also influence the sexual strategy adult females will adopt later in life. Lower levels of maternal care are associated with early onset of puberty as well as increased motivation to mate and greater receptivity toward males during mating. Lower levels of maternal care are also correlated with greater activity of the hypothalamus-pituitary-gonadal axis, responsible for the expression of these behaviors. Contrary to the transition of maternal care, sexual behavior cannot simply be explained by maternal attention, since adoption studies changed the sexual phenotypes of offspring born to low caring mothers but not those from high caring dams. Indeed, mothers showing higher levels of licking/grooming have embryos that are exposed to high testosterone levels during development, and adoption studies suggest that this androgen exposure may protect their offspring from lower levels of maternal care. We propose that in the rat, maternal care and the in utero environment interact to influence the reproductive strategy female offspring display in adulthood and that this favors the species by allowing it to thrive under different environmental conditions.

Parenting and Adolescents’ Sexual Development in Western Societies

This review examines associations between parenting styles and the psychosexual development of adolescents. Methods and results of empirical studies of associations between parental support, control, and knowledge and the sexual behavior and sexual health of adolescents are described and evaluated. The results show that, in general, higher scores on support, control, and knowledge relate to a delay of first sexual intercourse, safer sexual practices, and higher sexual competence. Despite the vast amount of literature on this subject, the majority of these studies focus on single dimensions of parenting and unidirectional parenting influences. This review generates hypotheses regarding interactions of different parenting styles and reciprocal associations between parents and their children. There is a need for more dynamic, dialectical studies of parenting, and children’s sexual development.

Adolescence: what do transmission, transition, and translation have to do with it?

Negotiating the transition from dependence on parents to relative independence is not a unique demand for today's youth but has a long evolutionary history (transmission) and is shared across mammalian species (translation). However, behavioral changes observed during this period are often described as delinquent. This review examines changes in explorative and emotive behaviors during the transition into and out of adolescence and the underlying neurobiological bases in the context of adaptive and maladaptive functions.

All they need is love? Placing romantic stress in the context of other stressors: A 17-nation study

The present study focuses on romantic stress and coping styles in the context of identity and future-related stressors in 8,654 adolescents with a mean age of M = 15.3; SD = 1.84. The adolescents from 17 countries were grouped into seven regions, i.e., Mid-Europe, Northern Europe, Eastern Europe, Southern Europe, South Africa, South America, and the Middle East. Future-related stressors were perceived as being more stressful than romantic stressors by all adolescents, irrespective of the region in which they lived. Identity-related stressors were of greater concern to adolescents from South Africa, South America, and the Middle East. Romantic stress was much higher in adolescents from Mid-Europe and Southern Europe compared to adolescents from other regions. Roughly 80% of all adolescents employed adaptive coping styles in that they negotiated with the romantic partner, sought support from friends and others, and shared an overall positive outlook. Adolescents from Mid-, Northern, and Eastern Europe were the most active in negotiating and support-seeking when dealing with romantic stressors.

Connectedness as a predictor of sexual and reproductive health outcomes for youth

To review research examining the influence of "connectedness" on adolescent sexual and reproductive health (ASRH). Connectedness, or bonding, refers to the emotional attachment and commitment a child makes to social relationships in the family, peer group, school, community, or culture. A systematic review of behavioral research (1985-2007) was conducted. Inclusion criteria included examination of the association between a connectedness sub-construct and an ASRH outcome, use of multivariate analyses, sample size of >or=100, and publication in a peer-reviewed journal. Results were coded as protective, risk, or no association, and as longitudinal, or cross sectional. Findings from at least two longitudinal studies for a given outcome with consistent associations were considered sufficient evidence for a protective or risk association. Eight connectedness sub-constructs were reviewed: family connectedness (90 studies), parent-adolescent general communication (16 studies), parent-adolescent sexuality communication (58 studies), parental monitoring (61 studies), peer connectedness (nine studies), partner connectedness (12 studies), school connectedness (18 studies), and community connectedness (four studies). There was sufficient evidence to support a protective association with ASRH outcomes for family connectedness, general and sexuality-specific parent-adolescent communication, parental monitoring, partner connectedness, and school connectedness. Sufficient evidence of a risk association was identified for the parent overcontrol sub-construct of parental monitoring. Connectedness can be a protective factor for ASRH outcomes, and efforts to strengthen young people's pro-social relationships are a promising target for approaches to promote ASRH. Further study regarding specific sub-constructs as well as their combined influence is needed.

The quality of young people's heterosexual relationships: a longitudinal analysis of characteristics shaping subjective experience

CONTEXT

Research on young people's sexual relationships often overlooks subjective experiences and enjoyment. Perceived quality of sexual relationships may be related to gender, background characteristics, circumstances of first intercourse and subsequent sexual history.

METHODS

Longitudinal data from 13-16-year-olds who participated in randomized trials of school sex education in either Scotland (N=5,356) or England (N=6,269) were used to examine young people's subjective experiences of heterosexual relationships. Logistic regression models tested for associations between selected variables and pressure and regret at first intercourse, pressure and enjoyment at most recent intercourse, and three measures of relationship quality.

RESULTS

Of the 42% of youth who reported having had sex by follow-up, most assessed their first and most recent sexual relationships positively. Greater proportions of females than of males felt pressure at first sexual intercourse (19% vs. 10%), regretted their first time (38% vs. 20%) and did not enjoy their most recent sex (12% vs. 5%). Younger age at first sex was an important correlate of partner pressure and regret at first intercourse (odds ratios, 2.0 each, for those 13 or younger vs. 15-16-year-olds). Negative experiences were associated with less control (e.g., feeling pressure, being drunk or stoned, and not planning sex) and with less intimacy (e.g., sex with a casual partner and less frequent sex). Background social characteristics had limited influence compared with circumstances of first intercourse and subsequent sexual history.

CONCLUSION

Most young people evaluated their early sexual experiences positively. The quality of relationships was enhanced by better communication and greater physical intimacy. For a vulnerable minority, however, early sexual experiences were negative. They could be protected by delaying first intercourse, restricting sexual activity to established relationships and learning skills to improve control in sexual encounters.

The under-controlled do it first: childhood personality and sexual debut

The relationship of childhood personality type to the timing of first sexual intercourse was investigated through survival analysis. Participants from the Child Sample of the National Longitudinal Survey of Youth were categorized into one of the three personality types at 5 or 6 years of age: under-controlled, resilient, and over-controlled. Those categorized as under-controlled at 5 or 6 years of age were more likely than those resilient or over-controlled to have sexual intercourse before the age of 16. The extent to which three early adolescent factors--team/club membership, church attendance, and peer influence--mediate the association of childhood personality type to the timing of first sexual intercourse was also explored. The association of childhood personality to timing of first sexual intercourse was partially mediated by peer influence at 11 or 12 years of age. The findings are interpreted in light of their implications for researchers and practitioners interested in improving the health and well-being of children and adolescents.

Young women's narratives of same-sex sexual desire in adolescence

The aim of this study was to investigate young women's retrospective narratives of their experiences of same-sex sexual desire in adolescence. Seven women aged 19-25 were interviewed. An across-narrative analysis was conducted, producing five major themes. It is anticipated that this research will help to redress the missing discourse of desire in social constructions of younger women's sexuality and contribute to the development of knowledge and research related to queer female adolescent sexuality and sexual health.

Stepfather involvement and adolescents' disposition toward having sex

CONTEXT

Existing literature suggests that stepfather relationships may be associated with adolescents' attitudes toward sex. Given the large number of children living with stepfathers, these associations call for the attention of researchers and intervention programs.

METHODS

Attitudes toward sex among participants in the first wave (1994-1995) of the National Longitudinal Study of Adolescent Health (Add Health) who were living in households headed by biological mothers and stepfathers were analyzed using linear regression models. Parental involvement and maternal attitudes toward sex were included as predictors.

RESULTS

The greater the involvement between adolescents and their stepfathers, the less positively disposed adolescents are toward having sex; however, the association holds only for males. Females' dispositions toward sex are tied to their religiosity and their mothers' attitudes toward sex. Both males and females who are sexually experienced view sex more positively than do those who have never had sex.

CONCLUSIONS

Different factors influence males' and females' motivations to engage in sex, and intervention programs need to be structured with these differences in mind. Programs that work toward cultivating close relationships between stepfathers and stepchildren will likely be most effective for males, while programs that highlight the important role that mothers play in making clear their beliefs about the acceptability of teenagers' sexual activity will likely be most effective for females.

Sexual Development and behaviors of adolescents

Adolescents are faced with many developmental tasks related to sexuality, such as forming romantic relationships and developing their sexual identities. Many adolescents will engage in a variety of sexual behaviors, including perhaps oral and anal sex, during this time period. Almost half will engage in vaginal sexual intercourse by the end of high school. A number of biological, psychosocial, and sociocultural factors can influence adolescents' romantic relationships and sexual behaviors. Some of these factors (eg, exposure to violence in the home, early pubertal development) may increase an adolescent's risk of being in an unhealthy relationship or engaging in sex at an early age. Parents, healthcare providers, and communities can support adolescents through these developmental tasks by forming close, connected relationships with teens and devising age-appropriate messages about the development of healthy sexuality.

Having a good relationship with their mother: a protective factor against sexual risk behavior among adolescent females?

STUDY OBJECTIVE

To assess whether having a good relationship with their mother was a protective factor against risky sexual behavior for female adolescents and whether it was independent of family structure.

DESIGN

Cross-sectional survey of in-school adolescents aged 14-19 years.

SETTING

Catalonia, in northeast Spain.

PARTICIPANTS

A total of 3677 females divided according on whether they had a good (n=3335) or a bad (n=342) relationship with their mother.

MAIN OUTCOME MEASURES

Rates of sexual activity and sexual behavior.

RESULTS

Adolescents in the good relationship group were significantly younger, more likely to live in an intact family, to have a good relationship with their father and siblings, and to talk about sexuality and their partner with their mother. They were also less likely to have ever had sexual intercourse. Among those sexually experienced, they were significantly older at first intercourse and less likely to have multiple partners or a history of STI. After adjusting for potential confounders, females in the good relationship group were less likely to be sexually active and to have had multiple partners, independently of family structure.

CONCLUSIONS

Having a good relationship with their mother is a protective factor against sexual intercourse and having multiple sexual partners independently of family structure. Communication between generations and having a good relationship with their father and siblings also play an important role.

Adolescent girls perceptions of the timing of their sexual initiation: "too young" or "just right"?

PURPOSE

To examine variables associated with adolescent girls' perceptions of the timing of their first consensual intercourse.

METHODS

One hundred seventy-four primarily African-American adolescent girls, aged 12 to 15 years participated in a 3-year longitudinal study of psychosexual development. Seventy-three percent reported being sexually experienced by the end of the study. They were asked whether they believed their age of initiation was "too young," "too old," or "just right." A generalized estimating equation (GEE) model was used to evaluate predictors of perception of timing of first consensual intercourse.

RESULTS

Ninety-nine (78%) said that they were "too young" and 28 (22%) said that their age had been "just right." The results of the final GEE model indicated that variables associated with perceiving age of first consensual intercourse as "just right" included younger chronological age, an older age of first consensual intercourse, endorsement of being "in love" as a reason for first consensual intercourse, greater indirect parental monitoring (vs. "none" or "direct parental monitoring"), and a higher level of education for mothers.

CONCLUSIONS

Most of these adolescents thought their age of initiation was too young. Factors associated with perceiving the timing of consensual intercourse as "just right" are similar to those reported in the literature to be associated with delaying the initiation of consensual intercourse.

Risky parental behavior and adolescent sexual activity at first coitus

Data from the National Longitudinal Study of Adolescent Health (Add Health) were used to examine the impact of parents' behavior on adolescents' sexual experience and contraceptive use. All else being equal, adolescents whose parents engage in risky behaviors are especially likely to be sexually active and to have had sex before age 15. These findings are only partly attributable to the link between parents' risky behaviors (smoking, drinking, driving without seatbelts) and adolescents' risky behaviors (smoking, drinking, delinquent activity, association with substance-using peers). Although parental behaviors are effective predictors of adolescents' sexual activity, they are not effective predictors of contraceptive use or of method choice at first coitus. Overall, parents with low levels of self-efficacy seem to be especially likely to have children at risk of engaging in problem behaviors.

Sexual initiation: predictors and developmental trends

BACKGROUND

Early initiation of sexual intercourse is associated with increased risk for acquiring sexually transmitted diseases.

GOAL

To examine variables related to sexual initiation and developmental changes in the reasons why adolescent girls have sexual intercourse.

STUDY DESIGN

A longitudinal study of girls recruited from an adolescent medicine clinic was performed.

RESULTS

Logistic regression showed that girls who described their families as being expressive, having a moral-religious emphasis, providing supervision, and having greater maternal education, and who experienced menarche at an older age were older at sexual initiation. On the basis of contingency analyses, younger girls were less likely to report attraction or love, and more likely to report peers having sex as a reason for sexual intercourse at initiation. A generalized estimating equation analysis indicated that girls at younger ages are more likely to report curiosity, a grown-up feeling, partner pressure, and friends having sexual intercourse as reasons for intercourse. Girls at older ages are more likely to report a feeling of being in love, physical attraction, too excited to stop, drunk or high partner, and feeling romantic as reasons for having sexual intercourse.

CONCLUSIONS

Prevention programs should include a focus on familial characteristics and susceptibility to peer norms. They should be conducted with sensitivity to the developmental changes in intimate relationships that occur during adolescence.
