Sperm donor lifestyle survey: modifiable risk factors for potential sperm donors.

OBJECTIVES: To examine the association between modifiable lifestyle factors and the main semen parameter values, the number of qualified sperm donors, and to provide some sensible guidance for sperm donors. METHODS: Healthy men screened as potential sperm donors were recruited in the Hunan Province Human Sperm Bank of China from March 2019 to December 2019. Participants were invited to complete interviewer-assisted questionnaires on eleven items of information. Univariate and multivariate analyses were conducted to analyze which lifestyle factors collected by the questionnaire had an impact on the eligibility and main semen parameters of sperm donors. RESULTS: The eligibility of men as sperm donors was strongly influenced by the duration of abstinence (P = 0.002). The rate of eligibility sperm donors increased significantly with the number of days of abstinence. In addition, semen volume increased with abstinence time (P = 0.000). Exercise frequency (P = 0.025) and abstinence time (P = 0.000) were positively correlated with sperm concentration, and masturbation frequency was negatively correlated with sperm concentration (P = 0.013). Progressive sperm motility was significantly affected by abstinence time (P = 0.000) and bedtime (P = 0.047). CONCLUSIONS: Abstinence time was highly associated with semen parameters and donor qualification. Increase the abstinence time before donation may be meaningful in improving the proportion of eligible sperm donors.

Preserving Abstinence and Preventing Rape: How Sex Education Textbooks Contribute to Rape Culture.

Recent academic and popular conversations regarding #MeToo, sexual violence and harassment, and rape culture have begun to focus on K-12 educational spaces in the U.S., but they rarely examine how educational curricula actually foster or combat these dynamics. In this article, we present a qualitative content analysis of health education textbooks, which explores the following question: What implicit and explicit messages do youth receive about sexual violence, and specifically, sexual violence prevention in health education textbooks? As we explored this question, we analyzed the roles that sex education curricula may play in shaping (e.g., contributing to, intervening upon) rape culture. We found the following messages across textbooks: abstinence is the only way to preserve one's safety; lack of abstinence increases risks, including the risk of being raped; and girls/women must assume personal responsibility and enact strategies that preserve one's abstinence and prevent them from being raped. This article concludes by teasing out how curricula can shape interactions, relationships, and culture, and by offering recommendations for improving sex education curricula.

Increasing role of abstinence and infecundity in non-use of contraceptive methods in India.

This paper assesses the reasons for non-use of contraceptive methods, and the possible complexity of reported data on women in India. The study used recent data from two successive rounds of the National Family Health Survey (NFHS) (2005-06: N=37,296; 2015-16: N=247,024), which surveyed currently married women aged 15-49 years. The reporting on non-use of contraceptives and the changing pattern of the reasons for non-use were analysed, classified into fertility and other cited reasons. The self-reported reasons for non-use of contraception were verified with other related information captured in the survey. Bivariate and logistic regression analyses were conducted. Sexual abstinence (not having sex: 10%; infrequent sex: 3%) and infecundity (menopausal/hysterectomy: 12%; subfecund/infecund: 10%) were the most commonly reported reasons for non-use of contraceptive methods in 2015-16, followed by refusal to use (10%). The proportion of non-users who wanted to have a child soon (25% to 21%), were pregnant (16% to 13%), in postpartum amenorrhoea (68% to 40%) and who had method-related reasons (10% to 6%) declined over time (from 2005-06 to 2015-16, respectively). A higher proportion of less-educated women reported abstinence (6%) and menopause/hysterectomy (19%) than educated women. Abstinence was more commonly reported in states with low prevalence of modern contraceptive use. The findings suggest that the increasing trend of abstinence and infecundity among non-users of contraception may be a concern for future research and reproductive health programmes, as it questions both the quality of data and sexual health of married couples.

Sexual Abstinence and Associated Factors Among Young and Middle-Aged Men: A Systematic Review.

INTRODUCTION: Sexual activity is an essential human need and an important predictor of other aspects of human life. A literature review was conducted to investigate whether sexual abstinence in young and middle-aged men is generally considered a deliberate, healthy behavior and whether it has other causes and consequences. AIM: To review the prevalence and factors associated with sexual abstinence in young (10-24 years) and middle-aged (25-59 years) men. METHODS: Studies were retrieved from Science Direct, PubMed, and EBSCOhost published from 2008 to 2019. The selection criteria were original population- or community-based articles, published in the English language, on sexual abstinence, and in young and middle-aged men. MAIN OUTCOME MEASURE: This article reviewed the literature on the proportions of and factors associated with sexual abstinence in young and middle-aged men. RESULTS: A total of 13,154 studies were retrieved, from which data were extracted for 37 population- or community-based studies. The prevalence of sexual abstinence varied from 0% to 83.6% in men younger than 60 years. The prevalence of primary sexual abstinence was 3.4%-83.3% for young men and 12.5%-15.5% for middle-aged men. The prevalence of secondary abstinence for young men ranged from 1.3% to 83.6%, while for middle-aged men, it was from 1.2% to 67.7%. The prevalence of sexual abstinence decreased with increasing age in young men but increased with increasing age in middle-aged men. The significant factors reported were age, single status, poor relationships, low socioeconomic status, sex education, religious practices, caring and monitoring parents, and not using alcohol, cigarettes, or drugs. Although the variations in findings from different studies can be explained by different regions and cultures, the information cannot be generalized worldwide because of a lack of studies in Asian and Australian populations. CLINICAL IMPLICATIONS: The studies on sexual abstinence in the future should use a consistent and standard definition, cover all sexual behaviors, and investigate all related factors. STRENGTH & LIMITATIONS: The restricted timeframe (2008-2019), English language, availability of full text, and variability in definition and time duration may be the sources of bias. CONCLUSION: Young men had higher proportions of sexual abstinence than middle-aged men, and age, unavailability of a partner, lower educational levels, low socioeconomic status, conservative and religious conditions, and no or less knowledge about sexually transmitted infections were common predictors of sexual abstinence in most of the men. Although determinants of sexual abstinence were identified, further investigation of biological factors in men younger than 60 years is needed. Irfan M, Hussain NHN, Noor NM, et al.

Frequency of Sexual Activity and Long-term Survival after Acute Myocardial Infarction.

BACKGROUND: Previous studies have shown an inverse relationship between sexual activity and mortality in the general population. We evaluated the association between sexual activity and long-term survival among patients with acute myocardial infarction. METHODS: Patients aged ≤65 years (n=1120; mean age, 53) discharged from 8 hospitals in central Israel after first myocardial infarction from 1992-1993 were followed for mortality through 2015. Frequency of sexual activity was self-reported during the index hospitalization (baseline; referring to the year preceding the infarct) and after 5 and 10-13 years, along with sociodemographic and clinical data. Cox proportional hazards models were constructed to estimate the association with all-cause mortality in time-dependent sexual activity categories. RESULTS: At baseline, a > once per week frequency of sexual activity was reported by 42% of the patients, whereas no sexual activity was reported by 6%. After 10-13 years, the rates were 21% and 27%, respectively. Lower sexual activity was associated with older age, female sex, lack of a steady partner and more comorbidities. During follow-up, 524 deaths (47%) occurred. An inverse relationship was observed between sexual activity frequency and death, with hazard ratios (95% confidence intervals) of 0.30 (0.23-0.38) for > once per week, 0.36 (0.28-0.46) for once per week, and 0.53 (0.42-0.66) for < once per week, compared with none. After adjusting for relevant confounding factors, the estimates were attenuated to 0.68 (0.50-0.91), 0.63 (0.48-0.83), and 0.72 (0.57-0.93), respectively (P for trend = .004). CONCLUSIONS: Using repeated assessments of sexual activity after myocardial infarction, an inverse association was demonstrated with mortality, which was only partly accounted for by measured potential confounders.

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.

Exploring the Protective Effects of Judaism on Risky Behaviors in College Students: A Pilot Study.

BACKGROUND: Common risky behaviors among college-aged young adults include risky sexual behaviors and substance use. PURPOSE: This study examines the protective effects of Judaism on students' engagement in risky behaviors, building on a body of research on the protective effects of religious beliefs on risky health behaviors. METHODS: Validated and reliable measures were used to assess religiosity and risky behaviors through anonymous surveys. Data was collected in Fall 2018 from a small cohort (N = 15) of Jewish day school students. RESULTS: Females had overall higher rates of risky behaviors such as drinking or using drugs before sex (27% compared to 13% for males), not using condoms (62% to 0% for males), and higher rates of binge drinking (62% to 20% for males). CONCLUSION: Higher religiosity was more associated with delayed sexual activity than substance use behaviors. Judaism and religiosity were more strongly associated with the male participants than the female. PRACTICE IMPLICATIONS: Since the participants still had low rates of condom use and other high risk behaviors despite speaking with their healthcare providers, the health care community must better educate adolescents and young adults on the health and social consequences of such risky activities, both in formal education programs during middle and high school, and in office visits.

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 .

Correlates of sexual inactivity and met need for contraceptives among young women in Ghana.

BACKGROUND: Young women in sub-Saharan Africa continue to experience unintended pregnancies despite effective contraceptive methods being more readily available than ever. This study sought to determine the correlates of met need for contraceptives and sexual inactivity among young women in Ghana who want to postpone childbearing. We examine this among all women and then separately by marital status. METHODS: Using data from 1532 females aged 15-24 years from the 2014 Ghana Demographic and Health Survey, we conducted descriptive and multinomial logistic regression analyses to assess sociodemographic, economic and obstetric determinants of the type of family planning method (current abstinence, modern contraceptive method) used by married and unmarried young women. RESULTS: A higher proportion (~ 44%) of the respondents was currently abstinent compared to those with met need (~ 25%). Abstinence was higher among single young women while unmet and met need were higher among the married. Having at least senior high school education was significantly associated with the likelihood of current abstinence (especially among single women) and with met need. Being in the middle and rich categories, on the other hand, was associated with lower likelihood of current abstinence and a met need. Compared with multiparous women, those with one or no surviving child had a lower likelihood of being abstinent and having a met need. Other correlates of both current abstinence and met need are region of residence and ethnicity, while previous pregnancy termination and age were associated with abstinence and contraceptive use, respectively. CONCLUSIONS: Unmet need is high among young women but abstinence is an option they are using. As reproductive health programmes target the at-risk groups, the secondary and higher educational levels must be attained by most women as this is associated with use of abstinence and met need.

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.

Technology-Based Interventions to Reduce Sexually Transmitted Infections and Unintended Pregnancy Among Youth.

PURPOSE: Technology-based interventions to promote sexual health have proliferated in recent years, yet their efficacy among youth has not been meta-analyzed. This study synthesizes the literature on technology-based sexual health interventions among youth. METHODS: Studies were included if they (1) sampled youth ages 13-24; (2) utilized technology-based platforms; (3) measured condom use or abstinence as outcomes; (4) evaluated program effects with experimental or quasi-experimental designs; and (5) were published in English. RESULTS: Sixteen studies with 11,525 youth were synthesized. There was a significant weighted mean effect of technology-based interventions on condom use (d = .23, 95% confidence interval [CI] [.12, .34], p < .001) and abstinence (d = .21, 95% CI [.02, .40], p = .027). Effects did not differ by age, gender, country, intervention dose, interactivity, or program tailoring. However, effects were stronger when assessed with short-term (1-5 months) than with longer term (greater than 6 months) follow-ups. Compared with control programs, technology-based interventions were also more effective in increasing sexual health knowledge (d = .40, p < .001) and safer sex norms (d = .15, p = .022) and attitudes (d = .12, p= .016). CONCLUSIONS: After 15 years of research on youth-focused technology-based interventions, this meta-analysis demonstrates their promise to improve safer sex behavior and cognitions. Future work should adapt interventions to extend their protective effects over time.

An Abstinence and Safer Sex Intervention for Adolescents Attending the Public Sexually Transmitted Infection Clinic in Singapore.

PURPOSE: The objective of this study was to evaluate the efficacy of a behavioral intervention in increasing secondary abstinence and safer sex among heterosexually active adolescents aged 16-19 years. METHODS: This was a randomized controlled trial conducted at the only national sexually transmitted infection clinic in Singapore. The intervention focused on information giving, motivation, and skills building to abstain or practice safer sex. The outcome measures were self-reported secondary abstinence, consistent condom use, and keeping to one partner in the past 6 months over a 12-month period. We recruited 688 adolescents, with 337 participants receiving intervention and 351 receiving standard care (control). RESULTS: At the 12-month follow-up, 187 (56%) intervention participants and 189 (54%) control participants were retained. Over the 12-month period, the intervention had a significant effect on secondary abstinence in adolescent boys (42% vs. 27%, adjusted risk ratio [aRR] 1.80, 95% confidence interval [CI] 1.29-2.34) but not in adolescent girls (21% vs. 24%, aRR 1.10, 95% CI .68-1.66). Consistent condom use was higher among intervention adolescent girls than control adolescent girls (40% vs. 20%, aRR 2.01, 95% CI 1.32-2.82), but this effect was not evident in adolescent boys (51% vs. 43%, aRR 1.27, 95% CI .78-1.88). Intervention effect on keeping to one partner was evident in both adolescent boys (76% vs. 45%, aRR 1.35, 95% CI 1.06-1.50) and adolescent girls (79% vs. 65%, aRR 1.20, 95% CI 1.02-1.23). CONCLUSIONS: An intervention targeting adolescents in a clinical care setting did achieve an increase in secondary abstinence in adolescent boys, consistent condom use in adolescent girls, and keeping to one partner in both genders at 1-year assessment.

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.

Comparison of comprehensive and abstinence-only sexuality education in young African American adolescents.

The purpose of this study was to identify predictors of sexual behavior and condom use in African American adolescents, as well as to evaluate the effectiveness of comprehensive sexuality and abstinence-only education to reduce adolescent sexual behavior and increase condom use. Participants included 450 adolescents aged 12-14 years in the southern United States. Regression analyses showed favorable attitudes toward sexual behavior and social norms significantly predicted recent sexual behavior, and favorable attitudes toward condoms significantly predicted condom usage. Self-efficacy was not found to be predictive of adolescents' sexual behavior or condom use. There were no significant differences in recent sexual behavior based on type of sexuality education. Adolescents who received abstinence-only education had reduced favorable attitudes toward condom use, and were more likely to have unprotected sex than the comparison group. Findings suggest that adolescents who receive abstinence-only education are at greater risk of engaging in unprotected sex.

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.

Impacts of Abstinence Time on Semen Parameters in a Large Population-based Cohort of Subfertile Men.

OBJECTIVE: To assess the effects of abstinence time on semen parameters in normozoospermic and oligozoospermic men using a large cohort of subfertile men. MATERIALS AND METHODS: From 2002 to 2013, we retrospectively reviewed data from 15,623 patients seen at our fertility clinic. Data on patient age and semen parameters were extracted along with abstinence time. Abstinence time was categorized into 4 groups (≤2 days; >2 and ≤5 days; >5 and ≤7 days; and >7 days). Semen samples were further categorized as normozoospermic or oligozoospermic based on concentration. Age-adjusted linear mixed effect regression models were used to test the effect of abstinence categories on semen parameters. RESULTS: Data from 11,782 encounters (10,095 patients) were used for the final analysis after excluding patients <18 years old, azoospermic samples, and those missing all semen parameters. Mean age was 32.4 (standard deviation: 6.5) and median abstinence time was 4.0 days. There were 9840 normozoospermic and 1939 oligozoospermic samples. In normozoospermic men, longer abstinence was associated with increases in ejaculate volume, concentration, total sperm count, and total motile sperm count. However, in oligozoospermic men, longer abstinence time was not associated with improvements in semen parameters except ejaculate volume. CONCLUSION: The effects of abstinence are different on semen parameters in normozoospermic and oligozoospermic patients. Longer abstinence does not improve most semen parameters in oligozoospermic samples. The World Health Organization recommendations for 2-7 days of abstinence may not be beneficial for subfertile patients when timing is a factor.

Measures Taken to Prevent Zika Virus Infection During Pregnancy - Puerto Rico, 2016.

Zika virus infection during pregnancy remains a serious health threat in Puerto Rico. Infection during pregnancy can cause microcephaly, brain abnormalities, and other severe birth defects (1). From January 1, 2016 through March 29, 2017, Puerto Rico reported approximately 3,300 pregnant women with laboratory evidence of possible Zika virus infection (2). There is currently no vaccine or intervention to prevent the adverse effects of Zika virus infection during pregnancy; therefore, prevention has been the focus of public health activities, especially for pregnant women (3). CDC and the Puerto Rico Department of Health analyzed data from the Pregnancy Risk Assessment Monitoring System Zika Postpartum Emergency Response (PRAMS-ZPER) survey conducted from August through December 2016 among Puerto Rico residents with a live birth. Most women (98.1%) reported using at least one measure to avoid mosquitos in their home environment. However, only 45.8% of women reported wearing mosquito repellent daily, and 11.5% reported wearing pants and shirts with long sleeves daily. Approximately one third (38.5%) reported abstaining from sex or using condoms consistently throughout pregnancy. Overall, 76.9% of women reported having been tested for Zika virus by their health care provider during the first or second trimester of pregnancy. These results can be used to assess and refine Zika virus infection prevention messaging and interventions for pregnant women and to reinforce measures to promote prenatal testing for Zika.

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.
