Prevalence and types of sexual inactivity in Britain: analyses of national cross-sectional probability survey data.

OBJECTIVES: To examine how prevalence and context of sexual inactivity varies across the life-course, assess dissatisfaction with sex life among those who are sexually inactive and identify associations with factors that may represent reasons for sexual inactivity. DESIGN: Analysis of cross-sectional probability sample survey data. SETTING: British general population. PARTICIPANTS: 14 623 participants (n men: 6045 unweighted, 7245 weighted), aged 16-74 years, of the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), undertaken in 2010-2012. MAIN OUTCOME MEASURES: Sexual inactivity, defined as not reporting oral, vaginal or anal intercourse in the past year and further categorised into those who were sexually inexperienced (had never had sex), single or in a relationship. RESULTS: Overall, 15.9% (weighted n 1155/7245) of men and 22.2% (1646/7410) of women were sexually inactive (p<0.001). The proportion of sexually inactive individuals who were sexually inexperienced was larger among men than women (26.3% (304/1155) vs 16.3% (268/1646)), while the proportion who were singles was larger among women (49.8% (820/1646) vs 40.4% (467/1155)). Sexual inexperience was the most common type of sexual inactivity in early adulthood, with this declining with age. A minority of those who had sexual experience but were sexually inactive-34.8% (293/842) of men and 23.6% (319/1349) of women-reported being dissatisfied with their sex lives. Associations with sexual inactivity was observed for a range of sociodemographics and sexual behaviours/attitudes, for example, religion, ethnicity, Body mass index, height, employment status and index of multiple deprivation; these associations varied by type of sexual inactivity and gender. CONCLUSIONS: While sex is important for well-being, a non-negligible proportion of the population at all ages are sexually inactive, yet many are not dissatisfied with their situation, with implications for sex and relationship counselling.

Assessing the impact of an educational intervention program on sexual abstinence based on the health belief model amongst adolescent girls in Northern Ghana, a cluster randomised control trial.

BACKGROUND: Adolescent pregnancy is a worldwide problem because of its health, social, economic and political repercussions on the globe. Even though the rates of adolescent pregnancy have declined over the decade, there is still unacceptably high rates especially in lower and middle-income countries including Ghana. Although the problem has been widely investigated, there is little information on the effectiveness of different methods to improve adolescent sexual abstinence based on theoretical models. This study is aimed to assess an educational intervention program on sexual abstinence based on the Health Belief Model (HBM) among adolescent girls in Northern Ghana. METHODS: A cluster randomized control trial was conducted in Ghana from April to August 2018. Participants within the ages of 13-19 years were enrolled voluntarily from six randomly selected Senior High Schools (3 for intervention and 3 for control). A total of 363 adolescent were enrolled. A self-structured questionnaire was administered to both groups of participants at baseline and endpoint of the study. Control participants received their normal classes whiles the intervention group additionally received comprehensive sexuality education for 1 month. Qualified midwives conducted the health education program. At least two sessions were conducted for each participating class weekly. The lessons focused on perceived susceptibility, perceived severity of adolescent pregnancy, perceived benefits, perceived barriers to adolescent pregnancy prevention, personal and family values, perceived self-efficacy and knowledge of contraceptives. Educational strategies such as discussions, demonstrations, role-play and problem solving techniques were used to deliver the lessons. Sexual abstinence was the outcome variable of the study and it was measured after 3 months of the intervention. Binary logistic regression was used to assess the impact of the intervention on sexual abstinence practice. RESULTS: At baseline, there was no difference between control and intervention groups. The mean score of Knowledge and attitude for control were (58.17 and 139.42) and intervention (60.49 and 141.36) respectively. Abstinence practice was 69.4% for control and 71.6% in the intervention group. However, after the intervention, the mean score of knowledge and attitude for control were (87.58 and 194.12) respectively. Sexual abstinence in the control was 84.4% and intervention was 97.3% respectively. The educational interventions resulted in a significant difference in sexual abstinence between intervention and control groups (OR = 13.89, 95% Confidence Interval (2.46-78.18, P < 0.003). CONCLUSION: Educational intervention, which was guided by HBM, significantly improved sexual abstinence and the knowledge of adolescents on pregnancy prevention among the intervention group. Provision of comprehensive sex education guided by behavioural theories to adolescents at Senior High Schools in Ghana is recommended. TRIAL REGISTRATION: This trial was retrospectively registered in Protocol Registration and Results System (PRS) with trial number NCT03384251 .

Risk and Protective Factors Associated With Lifetime Sexual Experience Among Rural, Reservation-Based American Indian Youth.

Early sexual initiation is a catalyst for sexually transmitted infection and unintended pregnancy. American Indian/Alaska Native (AI/AN) youth initiate sex prior to age 13 more often than other U.S. youth, contributing to current inequalities in sexual health. Identifying what factors were associated with lifetime sexual experience among AI/AN youth can inform the development of primary prevention programming to delay sexual initiation, alleviate the costs of early sexual activity, and improve sexual health outcomes in this population. We analyzed cross-sectional data from 267 AI youth ages 13-19, recruited from a rural, reservation-based community. We used multivariate logistic regression models to estimate associations between independent variables and lifetime sexual experience (vaginal and/or anal sex) across the following categories: sociodemographic, knowledge, attitudes/perceptions, beliefs, intentions, skills, behaviors, and theoretical constructs. The sample was 56.2% female, mean age 15.1 years (SD = 1.7), and 22.5% were sexually experienced. In our final model, condom use self-efficacy (attitude/perception factor) and intentions to remain abstinent until marriage (intention factor) were associated with lower odds of lifetime sexual experience. Age (sociodemographic factor), intention to have sex (intention factor), use of any contraception (behavior factor), and higher response efficacy (theoretical construct) were associated with lifetime sexual experience. Of these, intention to have sex was the strongest indicator. These results both corroborate and contrast with other research conducted among rural, reservation-based AI/AN youth. Our findings show programs targeting intentions may have the greatest impact among reservation-based AI youth, and justify program delivery stratified by age group in this setting.

Associations Between Patterns of Sexual Initiation, Sexual Partnering, and Sexual Health Outcomes from Adolescence to Early Adulthood.

The goal of this study was to examine, in a nationally representative sample, relationships between various sexual initiation patterns, subsequent sexual partnerships, and related health outcomes from adolescence through early adulthood. Data were from a subset of 6587 respondents from the National Longitudinal Study of Adolescent to Adult Health. Bivariate analyses and adjusted logistic and ordinary least squares regression models were used to determine associations between membership in three sexual initiation classes, lifetime sexual partner counts, and multiple health outcomes, including lifetime sexually transmitted infection or disease (STI/STD) diagnosis, lifetime unintended pregnancy, and romantic relationship quality. Broadly, having fewer lifetime sexual partners was associated with lower odds of STI/STD diagnosis and unintended pregnancy, and better relationship quality; however, findings also indicated both within and between sexual initiation class differences in the relationship between lifetime sexual partners and all three health outcomes. In particular, results showed little variation in health outcomes by sexual partnering among those who postponed sexual activity, but members of the class characterized by early and atypical sexual initiation patterns who had fewer lifetime partners exhibited better health outcomes than most other initiation groups. These results show that while both sexual initiation and partnering patterns add important information for understanding sexual health from adolescence to early adulthood, partnering may be more relevant to these sexual health outcomes. Findings indicate a need for more comprehensive sexuality education focused on sexual risk reduction and promotion of relationship skills among adolescents and adults.

Abstinence-Only-Until-Marriage: An Updated Review of U.S. Policies and Programs and Their Impact.

Adolescence is marked by the emergence of human sexuality, sexual identity, and the initiation of intimate relations; within this context, abstinence from sexual intercourse can be a healthy choice. However, programs that promote abstinence-only-until-marriage (AOUM) or sexual risk avoidance are scientifically and ethically problematic and-as such-have been widely rejected by medical and public health professionals. Although abstinence is theoretically effective, in actual practice, intentions to abstain from sexual activity often fail. Given a rising age at first marriage around the world, a rapidly declining percentage of young people remain abstinent until marriage. Promotion of AOUM policies by the U.S. government has undermined sexuality education in the United States and in U.S. foreign aid programs; funding for AOUM continues in the United States. The weight of scientific evidence finds that AOUM programs are not effective in delaying initiation of sexual intercourse or changing other sexual risk behaviors. AOUM programs, as defined by U.S. federal funding requirements, inherently withhold information about human sexuality and may provide medically inaccurate and stigmatizing information. Thus, AOUM programs threaten fundamental human rights to health, information, and life. Young people need access to accurate and comprehensive sexual health information to protect their health and lives.

Implementation and assessment of a prevention with positives intervention among people living with HIV at five hospitals in Thailand.

BACKGROUND: We implemented a hospital-based prevention with positives (PwP) intervention among people living with HIV (PLHIV) that included HIV transmission risk screening, short HIV prevention messages, family planning, HIV disclosure counseling, and partner HIV testing at five hospitals in Thailand. We assessed changes in sexual risk behaviors among PLHIV who received the PwP services at the hospitals. METHODS: From January 2008-March 2009, we systematically selected a subset of PLHIV receiving care at the five hospitals to offer participation in the PwP intervention. We collected demographic, risk behavior, and laboratory data using a standardized questionnaire. We analyzed data from PLHIV who completed at least four visits, using generalized estimating equations to identify baseline participant characteristics that were associated with adopting sexual practices less likely to be associated with HIV transmission during follow-up. RESULTS: A total of 830 PLHIV were interviewed and 756 (91.1%) completed four visits. The median age of these 756 participants was 37 years, 400 (52.9%) were women, and 475 (62.8%) had a steady partner. At baseline, 353 (74.3%) of the steady partners had been tested for HIV and 132 (37.4%) had tested negative. Among the 756 PLHIV, 427 (56.5%) reported having sex in the 3 months before enrollment and 413 (54.6%) in the 3 months before the fourth visit. The proportion reporting having vaginal or anal sex without a condom decreased from 20.8% at baseline to 5.1% at the fourth visit (p<0.001). Factors associated (p<0.05) with abstinence or 100% condom use at follow-up visits included: completing ≥ two visits, being diagnosed with HIV for longer than 3 months, and receiving HIV prevention messages from a doctor (versus a nurse or counselor). CONCLUSION: Safe sex behaviors increased among PLHIV receiving PwP services, suggesting that expansion of hospital-based PwP services may reduce the number of new HIV infections in Thailand.

The Effects of State-Mandated Abstinence-Based Sex Education on Teen Health Outcomes.

In 2011, the USA had the second highest teen birth rate of any developed nation, according to the World Bank, . In an effort to lower teen pregnancy rates, several states have enacted policies requiring abstinence-based sex education. In this study, we utilize a difference-in-differences research design to analyze the causal effects of state-level sex education policies from 2000-2011 on various teen sexual health outcomes. We find that state-level abstinence education mandates have no effect on teen birth rates or abortion rates, although we find that state-level policies may affect teen sexually transmitted disease rates in some states.

Factors Associated With Intentions to Engage in Vaginal Intercourse Among Sexually Abstinent Missouri High School Freshmen.

BACKGROUND: We examine personal characteristics, alcohol consumption, normative beliefs, household factors, and extracurricular engagement associated with intentions to have intercourse before marriage among abstinent students. METHODS: Data were analyzed from 245 freshmen enrolled in a school-based abstinence-only-until-marriage program. Two binary logistic regression analyses identified factors associated with intentions to engage in intercourse before marriage and within the next year. RESULTS: Approximately 21% and 14% of participants reported intentions to have intercourse. Respondents participated in 2.2 (standard deviation [SD] = 1.2) extracurricular activities. Freshmen who were male, perceived their friends to approve of premarital sex, and consumed alcohol were more likely to report intentions to have intercourse. For every additional extracurricular activity in which freshmen participated, they were less likely to report intentions to have intercourse within the next year (odds ratio [OR] = 0.56). CONCLUSIONS: Factors such as extracurricular activities provide youth with opportunities to build supportive relationships, connect with peers and role models, and positively engage in schools and communities. Extracurricular activities typically already exist, have funding, and are generally well-supported. School-based strategies can increase teenagers' autonomy by providing a variety of activities to participate in and reduce unsupervised time. This, in turn, has the potential to decrease sexual risk taking behaviors.

Community-based abstinence education project: program outcomes.

PROBLEM: Middle school and adolescent populations demonstrate high rates of unintended pregnancies and sexually transmitted infections, with young people in inner cities in the United States especially vulnerable. Teen births remain high, and youth are affected physically, mentally, socially, and economically. METHODS: The Sex After Marriage primary prevention program, a federally funded, community-based abstinence education (CBAE) initiative, was implemented for 3 years in Philadelphia neighborhoods with vulnerable youth 12 to 18 years of age, supporting adults, healthcare professionals, and the general public. The three-tiered program offered a middle school curriculum, Sex Can Wait, at 16 different sites. The CBAE program delivered by the university's nursing center attempted to support vulnerable youths' decisions to postpone sexual activity by matching the interests of young people through an established curriculum, by holding workshops for supporting adults, and by creating a multimedia approach to supplement abstinence education initiatives including public service announcements and a website. Youth and college ambassadors and community colleagues were trained in the curriculum with a focus on healthy lifestyles. Youth and parents in experimental and control groups completed self-report surveys before and after program implementation. FINDINGS: The project achieved most of its objectives on program evaluation. Youth (n = 1,428) 12 to 18 years of age received services, with most completing ≥75% of the program. Parents (n = 338) and other participating adults (n = 486) also received education or services. CONCLUSIONS: The need for risk reduction programs persists for youth in light of pregnancy, birth, and sexually transmitted disease statistics. Bailey Wolf.

The association between sexual orientation identity and behavior across race/ethnicity, sex, and age in a probability sample of high school students.

OBJECTIVES: We examined the prevalence and associations between behavioral and identity dimensions of sexual orientation among adolescents in the United States, with consideration of differences associated with race/ethnicity, sex, and age. METHODS: We used pooled data from 2005 and 2007 Youth Risk Behavior Surveys to estimate prevalence of sexual orientation variables within demographic sub-groups. We used multilevel logistic regression models to test differences in the association between sexual orientation identity and sexual behavior across groups. RESULTS: There was substantial incongruence between behavioral and identity dimensions of sexual orientation, which varied across sex and race/ethnicity. Whereas girls were more likely to identify as bisexual, boys showed a stronger association between same-sex behavior and a bisexual identity. The pattern of association of age with sexual orientation differed between boys and girls. CONCLUSIONS: Our results highlight demographic differences between 2 sexual orientation dimensions, and their congruence, among 13- to 18-year-old adolescents. Future research is needed to better understand the implications of such differences, particularly in the realm of health and health disparities.

Prevalence and predictors of sexual inexperience in adulthood.

The emergence of partnered sexual behavior represents an important developmental transition. However, little is known about individuals who remain sexually inexperienced well into adulthood. We used data from 2,857 individuals who participated in Waves I-IV of the National Longitudinal Study of Adolescent Health (Add Health) and reported no sexual activity (i.e., oral-genital, vaginal, or anal sex) by age 18 to identify, using discrete-time survival models, adolescent sociodemographic, biosocial, and behavioral characteristics that predicted adult sexual inexperience. The mean age of participants at Wave IV was 28.5 years (SD = 1.92). Over one out of eight participants who did not initiate sexual activity during adolescence remained abstinent as young adults. Sexual non-attraction significantly predicted sexual inexperience among both males (aOR = 0.5) and females (aOR = 0.6). Males also had lower odds of initiating sexual activity after age 18 if they were non-Hispanic Asian, reported later than average pubertal development, or were rated as physically unattractive (aORs = 0.6-0.7). Females who were overweight, had lower cognitive performance, or reported frequent religious attendance had lower odds of sexual experience (aORs = 0.7-0.8) while those who were rated by the interviewers as very attractive or whose parents had lower educational attainment had higher odds of sexual experience (aORs = 1.4-1.8). Our findings underscore the heterogeneity of this unique population and suggest that there are a number of different pathways that may lead to either voluntary or involuntary adult sexual inexperience. Understanding the meaning of sexual inexperience in young adulthood may have important implications for the study of sexuality development across the life course.

The timing of sexual debut among Chinese youth.

CONTEXT: The age at sexual debut is declining in China, but little is known about the relationship between the social and demographic characteristics of Chinese youth and the timing of debut. METHODS: Data were drawn from the 2009 National Youth Reproductive Health Survey, which collected background information and age at sexual debut from 22,300 unmarried youth aged 15-24. Life table analysis was used to estimate the gender-specific distributions of sexual debut by age, according to urban or rural residence and by region. Cox proportional hazard regression models were then employed to identify characteristics associated with the timing of debut among males and females. RESULTS: The mean age at sexual debut was 22.8 years (22.5 years for men and 23.1 years for women). Sexual debut before age 18 was rare for both genders, and ages 21-24 appear to be the normative range for sexual debut. Life table analysis found that debut was earlier for males than for females, for those living in a rural area than for those in urban areas, and for those living in western China than for those in other regions. In multivariate hazard regression analysis, males had a 30% greater risk of experiencing sexual debut within each year of age than did females. Living in a household with both biological parents, having a father with a junior or senior high school education, being a college graduate and living in an urban area were associated with a reduced risk of experiencing sexual debut. CONCLUSION: This study provides insight into the basic patterns and social and demographic correlates of sexual debut among Chinese youth.

Abstinence-only education and teen pregnancy rates: why we need comprehensive sex education in the U.S.

The United States ranks first among developed nations in rates of both teenage pregnancy and sexually transmitted diseases. In an effort to reduce these rates, the U.S. government has funded abstinence-only sex education programs for more than a decade. However, a public controversy remains over whether this investment has been successful and whether these programs should be continued. Using the most recent national data (2005) from all U.S. states with information on sex education laws or policies (N = 48), we show that increasing emphasis on abstinence education is positively correlated with teenage pregnancy and birth rates. This trend remains significant after accounting for socioeconomic status, teen educational attainment, ethnic composition of the teen population, and availability of Medicaid waivers for family planning services in each state. These data show clearly that abstinence-only education as a state policy is ineffective in preventing teenage pregnancy and may actually be contributing to the high teenage pregnancy rates in the U.S. In alignment with the new evidence-based Teen Pregnancy Prevention Initiative and the Precaution Adoption Process Model advocated by the National Institutes of Health, we propose the integration of comprehensive sex and STD education into the biology curriculum in middle and high school science classes and a parallel social studies curriculum that addresses risk-aversion behaviors and planning for the future.

Adolescent sexual abstinence: a test of an integrative theoretical framework.

The purpose of this study was to test an integrative theoretical framework in explaining adolescents' sexual abstinence and intentions to remain abstinent and refine the framework to reflect which elements contribute more powerfully to the explanation of abstinence and intentions. We administered an anonymous, theory-based questionnaire to two nonrandom samples of seventh- and eighth-graders (n = 451 and 447, respectively). Measurement modeling provided sufficient evidence for establishing construct validity. A refined structural equation model demonstrated good fit. Pro-abstinence standards predicted stronger beliefs toward staying abstinent, stronger perceptions that others endorse pro-abstinence norms, and a greater self-efficacy to remain sexually abstinent until marriage. In turn, beliefs, norms, and self-efficacy were predictive of intentions, which predicted sexual abstinence at a later time point. Similar findings emerged in a replication using a second set of sample data. Results suggest that this integrative theoretical framework is useful in explaining adolescents' intention and their subsequent sexual abstinence.

Efficacy of a theory-based abstinence-only intervention over 24 months: a randomized controlled trial with young adolescents.

OBJECTIVE: To evaluate the efficacy of an abstinence-only intervention in preventing sexual involvement in young adolescents. DESIGN: Randomized controlled trial. SETTING: Urban public schools. PARTICIPANTS: A total of 662 African American students in grades 6 and 7. INTERVENTIONS: An 8-hour abstinence-only intervention targeted reduced sexual intercourse; an 8-hour safer sex-only intervention targeted increased condom use; 8-hour and 12-hour comprehensive interventions targeted sexual intercourse and condom use; and an 8-hour health-promotion control intervention targeted health issues unrelated to sexual behavior. Participants also were randomized to receive or not receive an intervention maintenance program to extend intervention efficacy. OUTCOME MEASURES: The primary outcome was self-report of ever having sexual intercourse by the 24-month follow-up. Secondary outcomes were other sexual behaviors. RESULTS: The participants' mean age was 12.2 years; 53.5% were girls; and 84.4% were still enrolled at 24 months. Abstinence-only intervention reduced sexual initiation (risk ratio [RR], 0.67; 95% confidence interval [CI], 0.48-0.96). The model-estimated probability of ever having sexual intercourse by the 24-month follow-up was 33.5% in the abstinence-only intervention and 48.5% in the control group. Fewer abstinence-only intervention participants (20.6%) than control participants (29.0%) reported having coitus in the previous 3 months during the follow-up period (RR, 0.94; 95% CI, 0.90-0.99). Abstinence-only intervention did not affect condom use. The 8-hour (RR, 0.96; 95% CI, 0.92-1.00) and 12-hour comprehensive (RR, 0.95; 95% CI, 0.91-0.99) interventions reduced reports of having multiple partners compared with the control group. No other differences between interventions and controls were significant. CONCLUSION: Theory-based abstinence-only interventions may have an important role in preventing adolescent sexual involvement. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00640653.

Predictors of sexual abstinence behaviour in Taiwanese adolescents: a longitudinal application of the transtheoretical model.

AIMS AND OBJECTIVES: To understand (1) the change of stage of changes, self-efficacy, decisional balance and processes of change for sexual abstinence behaviour across a 15-month interval, (2) relations of baseline stage of changes, self-efficacy, decisional balance and processes of change to follow-up stage of changes for sexual abstinence and (3) the important predictors of follow-up stage of changes and transition of stage of changes for sexual abstinence behaviour. BACKGROUND: Examining factors of sexual abstinence behaviour among adolescents can provide useful information in designing sexual abstinence intervention programmes. DESIGN: This study applied a transtheoretical model and used a longitudinal design. METHOD: Anonymous questionnaires were administered to 281 participants at baseline and 15-month follow-up. RESULTS: In summary, 46.3% (n = 130) of the participants were in the same stage, 30.2% (n = 85) regressed and 23.5% (n = 66) progressed their stage from baseline to follow-up. Baseline self-efficacy, decisional balance and processes of change are related to follow-up stage of changes for sexual abstinence. Participants with higher baseline self-efficacy, lower decrease of self-efficacy from baseline to follow-up and lower decrease of decisional balance from baseline to follow-up were more in the definite group (preparation and action stage) at follow-up. Participants with higher baseline decisional balance, lower decrease of decisional balance from baseline to follow-up and lower decrease of self-efficacy from baseline to follow-up were more in the advancement transition group at follow-up. CONCLUSIONS: Focus of interventions could differ according to intervention purpose. Reducing the decrease of self-efficacy and decisional balance across time is important to enable adolescents to be in or progress to better stages across time. RELEVANCE TO CLINICAL PRACTICE: To make adolescents be in later stages at follow-up, increasing baseline self-efficacy is important. If the purpose is to progress the stages, baseline decisional balance should be emphasised. Health care providers should continually boost the self-efficacy and decisional balance of adolescents across time.

Variations in coital and noncoital sexual repertoire among adolescent women.

PURPOSE: Little is known about factors associated with the day-to-day selection and orchestration of sexual repertoire among adolescent women. Analyzing differences in adolescent women's sexual activity may augment both the clinical and behavioral understanding of sexuality development and sexual decision making, and may yield important points to enhance existing programs for prevention of sexually transmitted infection or pregnancy. METHODS: Adolescent women (N = 387, aged 14-17 years at enrollment) were recruited from primary care adolescent clinics serving primarily lower- and middle-income patients. Data were taken from daily sexual diaries. A four-category outcome variable, using generalized estimating equation multinomial logistic regression assessed the likelihood of specific sexual behaviors on a given day: none (abstinence), non-coital-only, coital-only, and dual noncoital/coitus. Separate models were analyzed for fellatio, cunnilingus, and anal sex. Predictor variables included age, menstrual bleeding, alcohol or marijuana use, positive or negative mood, recent coitus, recent noncoital sexual activity, partner support or negativity, sexual interest, feeling in love, time of the week, and same-day noncoital behaviors. Coital-only sexual behavior was used as the reference category. RESULTS: Among adolescent women, abstinence is prevalent on the majority of days. When sexual activity does occur, coital-only activity is most common; however, noncoital behaviors alone and/or in tandem with coitus are not rare. CONCLUSIONS: Differing associations of intrapersonal, partner and situational variables with specific types of day-to-day sexual activity underscores a complex sexual repertoire which may be insufficiently examined with a simple focus on coital risk.

Association of sexual abstinence in adolescence with mental health in adulthood.

We examined whether adolescent sexual abstinence predicts better adult mental health. 1,917 adolescents, recruited from middle schools at age 13, were surveyed at ages 13, 18, 23, and 29. In bivariate analyses, adolescent sexual abstinence was associated with better mental health at age 29 for females, but not males; three adolescent factors, educational prospects, family bonding, and unconventionality were investigated as explanatory variables of this relationship. The abstinence-mental health relationship was nonsignificant when educational prospects was included in multivariate models, and marginally significant when family bonding and unconventionality were included; all three explanatory factors accounted for significant proportions of the variance in adult mental health. Girls who are uninvolved in school, have weak family backgrounds, and exhibit unconventionality may have poor adult mental health, whether or not they abstain from sex in adolescence. Interventions that strengthen adolescents' connections to families and schools may reduce risk for long-term mental health problems.

Use of periodic abstinence in Bangladesh: do they really understand?

Data from a nationally representative study in Bangladesh (BDHS 1996-97) were analysed to identify significant predictors of use of periodic abstinence, in comparison with other modern contraceptive methods. The study found that women in Bangladesh mostly use modern methods during their peak reproductive years, after which some of them switch to periodic abstinence. These women tend to be more from educated and from higher socioeconomic backgrounds and with at least one living son. Another set of data from the Matlab DSS was analysed and the results were in the same direction. Focus group discussions found that women were using the periodic abstinence method incorrectly, abstaining for more days than is necessary. For Bangladeshi contraceptive users to reach a higher degree of use-effectiveness for period abstinence, more IEC materials need to be developed.

Factors associated with sexual abstinence among adolescents in four sub-Saharan African countries.

Drawing on nationally representative data collected from Burkinabé, Ghanaian, Malawian, and Ugandan adolescents, this study examines differences among four groups of never married, 15-19 year olds: primary abstainers (sexually inexperienced), secondary abstainers (last sex more than 12 months prior to the survey), recent abstainers (sexually active in last year but not in the last 3 months), and sexually active (had sexual intercourse in the last 3 months). The percentage of primary abstinent adolescents ranged from 42% (Malawian males) to 85% (Ghanaian males). In general, a greater proportion of females than males were primary abstainers. Primary abstainers were younger than sexually experienced adolescents. Current involvement in a romantic relationship was a significant predictor of sexual status with primary abstainers being the least likely to be romantically involved. Overall, findings suggest that adolescents' gender, prior sexual experiences and contextual circumstances, such as romantic partnerships, should be considered when designing abstinence promotion programs.
