National Needs of Family Planning Among US Men Aged 15 to 44 Years.

OBJECTIVES: To estimate national need for family planning services among men in the United States according to background characteristics, access to care, receipt of services, and contraception use. METHODS: We used weighted data from the 2006-2010 National Survey of Family Growth to estimate the percentage of men aged 15 to 44 years (n = 10 395) in need of family planning, based on sexual behavior, fecundity, and not trying to get pregnant with his partner. RESULTS: Overall, 60% of men were in need of family planning, defined as those who ever had vaginal sex, were fecund, and had fecund partner(s) who were not trying to get pregnant with partner or partner(s) were not currently pregnant. The greatest need was among young and unmarried men. Most men in need of family planning had access to care, but few reported receiving family planning services (< 19%), consistently using condoms (26%), or having partners consistently using contraception (41%). CONCLUSIONS: The need for engaging men aged 15 to 44 years in family planning education and care is substantial and largely unmet despite national public health priorities to include men in reducing unintended pregnancies.

Family Planning and Preconception Health Among Men in Their Mid-30s: Developing Indicators and Describing Need.

The Centers for Disease Control and Prevention and Healthy People 2020 call for improvements in meeting men's reproductive health needs but little is known about the proportion of men in need. This study describes men aged 35 to 39 in need of family planning and preconception care, demographic correlates of these needs, and contraception use among men in need of family planning. Using data from Wave 4 (2008-2010) of the National Survey of Adolescent Males, men were classified in need of family planning and preconception care if they reported sex with a female in the last year and believed that they and their partner were fecund; the former included men who were neither intentionally pregnant nor intending future children and the latter included men intending future children. Men were classified as being in need of both if they reported multiple sex partners in the past year. About 40% of men aged 35 to 39 were in need of family planning and about 33% in need of preconception care with 12% in need of both. Current partner's age, current union type, and sexually transmitted infection health risk differentiated men in need of family planning and preconception care (all ps < .01) and participants' race/ethnicity further differentiated men in need of preconception care (p < .01). More than half of men in need of family planning reported none of the time current partner hormonal use (55%) or condom use (52%) during the past year. This study identified that many men in their mid-30s are in need of family planning or preconception care.

Men Aged 15-44 in Need of Preconception Care.

OBJECTIVES: Preconception care for men focuses on prevention strategies implemented prior to conception of a first or subsequent pregnancy to improve pregnancy and infant outcomes. Little is known about U.S. men in need of preconception care. This analysis describes the proportion of men in need of preconception care and associations of these needs by background characteristics, related health conditions, access to care and receipt of services. METHODS: Data from men aged 15-44 in the National Survey of Family Growth 2006-2010 were analyzed to describe men in need of preconception care, based on future childbearing intentions and self and partner fecundity status (among sexually experienced only), and associated factors with these needs using weighted bivariate analyses. RESULTS: About 60 % of men are in need of preconception care. Higher prevalence of being in need was observed among men aged 15-29 than older; living in urban than non-urban settings; in school than not in school regardless of working status; not in a coresidential union than married or cohabiting; who were recent immigrants than U.S. born; and reporting never having had a child than ≥1 child(ren). Men in need were overweight/obese (56 %), ever binge drank in the last year (58 %), and have high STI risk (21 %). The majority of men in need reported access to care in the last year (>70 %), but few reported receipt of services including STD/HIV testing (<20 %) or counseling (<11 %). CONCLUSIONS FOR PRACTICE: Findings from this analysis have implications for promoting preconception care among U.S. men.

Depression outcomes associated with an intervention implemented in employment training programs for low-income adolescents and young adults.

IMPORTANCE: Recent estimates indicate that 6.5 million adolescents and young adults in the United States are neither in school nor working. These youth have significant mental health concerns that require intervention. OBJECTIVE: To determine whether a mental health intervention, integrated into an employment training program that serves adolescents and young adults disconnected from school and work, can reduce depressive symptoms and improve engaged coping strategies. DESIGN, SETTING, AND PARTICIPANTS: A quasi-experimental study was conducted; 512 adolescents and young adults newly enrolling in one employment training program site were intervention participants, while 270 youth from a second program site were enrolled as controls. Participants were aged 16 to 23 years and not in foster care. Study recruitment took place from September 1, 2008, to May 31, 2011, with follow-up data collection occurring for 12 months after recruitment. Propensity score matching adjusted for observed baseline differences between the intervention and control groups. MAIN OUTCOMES AND MEASURES: Depressive symptoms measured on a Center for Epidemiologic Studies Depression Scale (CES-D) and engaged coping strategies. RESULTS: The mean age of participants was 19 years, 93.7% were African American, and 49.4% were male. Six- and 12-month follow-up rates were 61.0% (n = 477) and 56.8% (n = 444), respectively. Males in the intervention group with high baseline depressive symptoms exhibited a statistically significant decrease in depressive symptoms at 12 months (5.64-point reduction in CES-D score; 95% CI, -10.30 to -0.96; P = .02) compared with similar males in the control group. A dosage effect was observed at 12 months after the intervention, whereby males with greater intervention exposure showed greater improvement in depressive symptoms compared with similar males with lower intervention doses (effect on mean change in CES-D score, -3.37; 95% CI, -6.72 to -0.09; P = .049). Males and females in the intervention group were more likely than participants in the control group to increase their engaged coping skills, with statistically significant differences found for males (effect on mean change in CES-D score, 0.32; 95% CI, 0.14-0.50; P = .001) and females (effect on mean change in CES-D score, 0.19; 95% CI, 0.01-0.37; P = .047) at 12 months. CONCLUSIONS AND RELEVANCE: Given the growing number of adolescents and young adults using employment training programs and the mental health needs of this population, increased efforts should be made to deliver mental health interventions in these settings that usually focus primarily on academic and job skills. Ways to extend the effect of intervention for females and those with lower levels of depressive symptoms should be explored.

The association between social support and mental health among vulnerable adolescents in five cities: findings from the study of the well-being of adolescents in vulnerable environments.

PURPOSE: Globally, adolescents are at risk of depression, traumatic stress, and suicide, especially those living in vulnerable environments. This article examines the mental health of 15- to 19-year-old youth in five cities and identifies the social support correlates of mental health. METHODS: A total of 2,393 adolescents aged 15-19 years in economically distressed neighborhoods in Baltimore, MD; New Delhi, India; Ibadan, Nigeria; Johannesburg, South Africa; and Shanghai, China were recruited in 2013 via respondent-driven sampling to participate in a survey using an audio computer-assisted self-interview. Weighted logistic regression and general linear models were used to explore the associations between mental health and social supports. RESULTS: The highest levels of depression and posttraumatic stress symptoms were displayed in Johannesburg among females (44.6% and 67.0%, respectively), whereas the lowest were among New Delhi females and males (13.0% and 16.3%, respectively). The prevalence of suicidal ideation ranged from 7.9% (New Delhi female adolescents) to 39.6% (Johannesburg female adolescents); the 12-month prevalence of suicide attempts ranged from 1.8% (New Delhi females) to 18.3% (Ibadan males). Elevated perceptions of having a caring female adult in the home and feeling connected to their neighborhoods were positively associated with adolescents' levels of hope across the sites while negatively associated with depression and posttraumatic stress symptoms with some variation across sites and gender. CONCLUSIONS: Adolescents living in the very economically distressed areas studied register high levels of depression and posttraumatic stress. Improving social supports in families and neighborhoods may alleviate distress and foster hope. In particular, strengthening supports from female caretakers to their adolescents at home may improve the outlooks of their daughters.

Predictors of substance use among vulnerable adolescents in five cities: findings from the well-being of adolescents in vulnerable environments study.

PURPOSE: Adolescent substance use has numerous consequences. Our goals in this article are to compare the prevalence and correlates of substance use among ethnically diverse adolescents. METHODS: Data were from 2,332 adolescents aged 15-19 years recruited via respondent-driven sampling from disadvantaged settings in five cities. Multivariate logistic regression was used to identify correlates of current substance use. RESULTS: About half of the respondents were male. Most adolescents (73.4%) were currently enrolled in school and identified a father (86.2%) and mother (98.6%) figure and strong peer support. Sixty-two percent reported lifetime use of at least one substance. Overall, the most common substances ever used were alcohol (44.6%), cigarettes (26.2%), and marijuana (17.9%). Mean age at first use of alcohol was 14.2 ± 3.1 years. Current alcohol use was highest in Johannesburg (47.4%) and lowest in Delhi (2.1%). The mean age at first use of cigarettes was 14.4 ± 2.8 years. Current cigarette smoking was highest in Johannesburg (32.5%) and lowest in Delhi (3.7%). Male gender predicted current alcohol use in all sites, older age (17-19 years) was also a predictor in Baltimore. Male gender (Johannesburg and Shanghai), older age (Baltimore and Shanghai), and being out of school (Baltimore, Johannesburg, and Shanghai) predicted current cigarette smoking. Absence of a caring father figure was predictive for current alcohol use in Baltimore and Shanghai. Stronger peer support predicted alcohol (Johannesburg and Shanghai) and cigarette use (Johannesburg). CONCLUSIONS: Substance use is still a major issue among adolescents around the world, underscoring the need for continued research and interventions.

Prevalence and determinants of adolescent pregnancy in urban disadvantaged settings across five cities.

PURPOSE: The impact of pregnancy on the health and livelihood of adolescents aged 15-19 years is substantial. This study explored sociodemographic, behavioral, and environmental-level factors associated with adolescent pregnancy across five urban disadvantaged settings. METHODS: The Well-Being of Adolescents in Vulnerable Environments study used respondent-driven sampling (RDS) to recruit males and females from Baltimore (456), Johannesburg (496), Ibadan (449), New Delhi (500), and Shanghai (438). RDS-II and poststratification age weights were used to explore the odds associated with "ever had sex" and "ever pregnant"; adjusted odds of pregnancy and 95% confidence interval were developed by site and gender. RESULTS: Among the sexually experienced, pregnancy was most common in Baltimore (females, 53% and males, 25%) and Johannesburg (females, 29% and males 22%). Heterosexual experience and therefore pregnancy were rare in Ibadan, New Delhi, and Shanghai. Current schooling and condom use at the first sex decreased the odds of pregnancy among females in Baltimore and Johannesburg participants. Factors associated with higher odds of pregnancy were early sexual debut (Johannesburg participants and Baltimore females) being raised by someone other than the two parents (Johannesburg females); alcohol use and binge drinking in the past month (Baltimore participants); greater community violence and poor physical environment (Baltimore males and Johannesburg participants). CONCLUSIONS: The reported prevalence of adolescent pregnancy varies substantially across similarly economically disadvantaged urban settings. These differences are related to large differences in sexual experience, which may be underreported, and differences in environmental contexts. Pregnancy risk needs to be understood within the specific context that adolescents reside with particular attention to neighborhood-level factors.

Respondent-driven sampling for an adolescent health study in vulnerable urban settings: a multi-country study.

The global adolescent population is larger than ever before and is rapidly urbanizing. Global surveillance systems to monitor youth health typically use household- and school-based recruitment methods. These systems risk not reaching the most marginalized youth made vulnerable by conditions of migration, civil conflict, and other forms of individual and structural vulnerability. We describe the methodology of the Well-Being of Adolescents in Vulnerable Environments survey, which used respondent-driven sampling (RDS) to recruit male and female youth aged 15-19 years and living in economically distressed urban settings in Baltimore, MD; Johannesburg, South Africa; Ibadan, Nigeria; New Delhi, India; and Shanghai, China (migrant youth only) for a cross-sectional study. We describe a shared recruitment and survey administration protocol across the five sites, present recruitment parameters, and illustrate challenges and necessary adaptations for use of RDS with youth in disadvantaged urban settings. We describe the reach of RDS into populations of youth who may be missed by traditional household- and school-based sampling. Across all sites, an estimated 9.6% were unstably housed; among those enrolled in school, absenteeism was pervasive with 29% having missed over 6 days of school in the past month. Overall findings confirm the feasibility, efficiency, and utility of RDS in quickly reaching diverse samples of youth, including those both in and out of school and those unstably housed, and provide direction for optimizing RDS methods with this population. In our rapidly urbanizing global landscape with an unprecedented youth population, RDS may serve as a valuable tool in complementing existing household- and school-based methods for health-related surveillance that can guide policy.

Clients' perceptions of service quality and satisfaction at their initial Title X family planning visit.

Family planning service quality and clients' satisfaction with services are important determinants of clients' contraceptive use and continuation. We examine women's experiences at family planning clinics on a range of dimensions, including patient-centered communication (PCC), and identify experiences associated with higher ratings of service quality and satisfaction. New female clients (n = 748), ages 18-35 years, from clinics in three major metropolitan areas completed computer-administered interviews between 2008 and 2009. Factors associated with primary outcomes of service quality and satisfaction were assessed using multinomial and ordinary logistic regression, respectively. Higher scores on a Clinician-Client Centeredness Scale, measuring whether clinicians were respectful, listened, and provided thoughtful explanations, were associated with perceptions of good quality care and being very satisfied. Higher scores on a Clinic Discomfort Scale, measuring staff and waiting-room experiences, were associated with reduced satisfaction. Clients' interactions with clinicians, especially PCC, influence their perceptions of service quality, whereas their satisfaction with services is also influenced by the facility environment. These measures are adaptable for agencies to identify the factors contributing to their own clients' satisfaction-dissatisfaction with care and perceptions of service quality.

Union status and sexual risk behavior among men in their 30s.

CONTEXT: Understanding the relationship between union status and men's sexual risk behavior in their 30s is important to ensure appropriate reproductive health services for men in middle adulthood. METHODS: Data from 1,083 men aged 34-41 who participated in the 2008-2010 wave of the National Survey of Adolescent Males were used to examine differentials in sexual risk behaviors by union status, past risk behavior and selected characteristics. Bivariate tabulations were done to assess relationships between current risk behavior and background variables, multinomial regression analysis was conducted to identify associations between union status and past risk behavior, and logistic regression analysis was used to assess associations between current behavior and both union status and past behavior. RESULTS: Eight percent of men in their 30s had had three or more sexual partners in the last 12 months, 10% had had at least one risky partner and 8% had had concurrent partners. Men living outside co-residential unions reported higher levels of these behaviors (24%, 29% and 24%, respectively) than did married men (1-2%) or cohabiting men (7-12%). In multivariate analyses that controlled for past risk behavior, married men were less likely than cohabiting men to have had at least one risky partner or concurrent partners in the last year (odds ratio, 0.2 for each), while men who were not in a co-residential union had an increased likelihood of reporting each risk behavior (2.2-5.3). CONCLUSIONS: Men in their 30s, especially those who are not married, engage in risky sexual behaviors. Further studies are needed to assess what contributes to behavioral differences by union status and what types of services might help men in this age-group reduce their risk.

Effectiveness of a brief curriculum to promote condom and health care use among out-of-school young adult males.

CONTEXT: Out-of-school black males aged 15-24 have higher levels of sexual risk-taking than in-school black males of the same age. However, few sexual risk reduction curricula are focused on out-of-school male youth. METHODS: A sexual and reproductive health intervention conducted at a Baltimore youth employment and training program in 2008-2010 was evaluated in a study involving 197 youth aged 16-24 from a predominantly black population. Ninety-eight participants received three one-hour curriculum sessions on consecutive days; 99 served as controls. At baseline and three months later, participants completed a survey assessing demographic characteristics and various knowledge, attitude and behavior measures. Regression analysis with random effects was used to assess differences between intervention participants and controls in changes in outcomes over time. RESULTS: In analyses adjusting for baseline characteristics, intervention participants showed greater improvements in outcomes between baseline and follow-up than did controls. Specifically, a male who received the intervention was more likely than a control male to report increases in knowledge of STDs and health care use (odds ratio, 1.6 for each), frequency of condom use (1.8), use of lubricant with condoms (23.6), communication with a provider about STDs (12.3) and STD testing (16.6). CONCLUSION: These findings suggest the potential benefits of integrating safer-sex and health care information into a sexual and reproductive health curriculum for out-of-school male youth.

Coping, stress, and social support associations with internalizing and externalizing behavior among urban adolescents and young adults: revelations from a cluster analysis.

PURPOSE: To use cluster analysis to explore how coping, stress, and social support align and intersect with each other and relate to internalizing and externalizing behavior among urban adolescents and young adults disconnected from school and work. METHODS: Baseline audio computer assisted self-interview (ACASI) data from a study of 683 urban, low-income, African-American 16-24-year-old youth (mean age = 18.7; SD = 1.8) participating in an employment training program was cluster analyzed. This method reveals how well youth group together based on coping strategies, stress exposure, and social support. RESULTS: Using four coping, two support, and two stress subscales, a three-cluster solution best fit the data. One cluster, representing 65% of the sample, was characterized by moderate coping, high support, and low stress. These youth also reported lower weapon carrying compared to youth in the remaining two clusters. Another cluster, representing 17% of the sample, was defined by high coping, moderate support, and high stress. Youth in this cluster reported the highest levels of depressive symptoms and high levels of suicidal ideation as well as high levels of perpetrating intimate partner violence compared to other youth. The final cluster, also representing 17% of the sample, was marked by low coping, low support, and low stress. These youth also reported high levels of suicidal ideation. CONCLUSIONS: Given the varying profiles of stress, support, and coping reported by urban adolescents and young adults, future research and policy should further explore targeted and tailored intervention approaches for these youth.

The association between developmental assets and sexual enjoyment among emerging adults.

PURPOSE: To examine the associations between three key developmental assets and an aspect of sexual health, sexual enjoyment, which has rarely been studied in young adults, although its importance is stressed in all recent sexual health policy statements. METHODS: Using data from wave III (2001-2002) of the National Longitudinal Study of Adolescent Health, and multiple logistic and ordered logistic regression, we explored the associations between sexual pleasure and autonomy, self-esteem, and empathy among 3,237 respondents aged 18-26 years in heterosexual relationships of ≥ 3-month duration. We also examined the distribution of sexual pleasure across various socio-demographic groups. RESULTS: Compared with young women, young men reported more regular orgasms and more enjoyment of two kinds of partnered sexual behavior. Sexual enjoyment was not associated with age, race/ethnicity, or socioeconomic status. Among women, autonomy, self-esteem, and empathy co-varied positively with all three sexual enjoyment measures. Among men, all associations were in the same direction, but not all were statistically significant. CONCLUSION: A substantial gender difference in enjoyment of partnered sexual behavior exists among emerging adults in the United States. This study is the first to use a representative population sample to find a relationship between developmental assets and a positive aspect of sexual health - sexual pleasure.

Pathways of early fatherhood, marriage, and employment: a latent class growth analysis.

In the National Longitudinal Survey of Youth 1979 (NLSY79), young fathers include heterogeneous subgroups with varying early life pathways in terms of fatherhood timing, the timing of first marriage, and holding full-time employment. Using latent class growth analysis with 10 observations between ages 18 and 37, we derived five latent classes with median ages of first fatherhood below the cohort median (26.4), constituting distinct early fatherhood pathways representing 32.4% of NLSY men: (A) Young Married Fathers, (B) Teen Married Fathers, (C) Young Underemployed Married Fathers, (D) Young Underemployed Single Fathers, and (E) Young Later-Marrying Fathers. A sixth latent class of men who become fathers around the cohort median, following full-time employment and marriage (On-Time On-Sequence Fathers), is the comparison group. With sociodemographic background controlled, all early fatherhood pathways show disadvantage in at least some later-life circumstances (earnings, educational attainment, marital status, and incarceration). The extent of disadvantage is greater when early fatherhood occurs at relatively younger ages (before age 20), occurs outside marriage, or occurs outside full-time employment. The relative disadvantage associated with early fatherhood, unlike early motherhood, increases over the life course.

Racial and ethnic disparities in sexual risk behaviors and STDs during young men's transition to adulthood.

CONTEXT: Racial and ethnic health disparities are an important issue in the United States. The extent to which racial and ethnic differences in STDs among youth are related to differences in socioeconomic characteristics and risky sexual behaviors requires investigation. METHODS: Data from three waves of the National Survey of Adolescent Males (1988, 1990-1991 and 1995) were used to examine 1,880 young men's history of STDs and their patterns and trajectories of sexual risk behavior during adolescence and early adulthood. Multinomial and logistic regression analyses were conducted to test whether racial and ethnic differences in STDs are due to the lower socioeconomic status and higher levels of risky sexual behavior among minority groups. RESULTS: Young black men reported the highest rates of sexual risk and STDs at each wave and across waves. Compared with white men, black and Latino men had higher odds of maintaining high sexual risk and increasing sexual risk over time (odds ratios, 1.7-1.9). In multivariate analyses controlling for socioeconomic characteristics, black men were more likely than white men to have a history of STDs (3.2-5.0); disparities persisted in analyses controlling for level of risky sexual behavior. CONCLUSIONS: Race and ethnicity continue to differentiate young black and Latino men from their white peers in terms of STDs. Prevention programs that target different racial and ethnic subgroups of adolescent men and address both individual- and contextual-level factors are needed to curb STD incidence.

Associations of Family and Peer Experiences with Masculinity Attitude Trajectories at the Individual and Group Level in Adolescent and Young Adult Males.

Data were drawn from 845 males in the National Survey of Adolescent Males who were initially aged 15-17, and followed-up 2.5 and 4.5 years later, to their early twenties. Mixed-effects regression models (MRM) and semiparametric trajectory analyses (STA) modeled patterns of change in masculinity attitudes at the individual and group levels, guided by gender intensification theory and cognitive-developmental theory. Overall, men's masculinity attitudes became significantly less traditional between middle adolescence and early adulthood. In MRM analyses using time-varying covariates, maintaining paternal coresidence and continuing to have first sex in uncommitted heterosexual relationships were significantly associated with masculinity attitudes remaining relatively traditional. The STA modeling identified three distinct patterns of change in masculinity attitudes. A traditional-liberalizing trajectory of masculinity attitudes was most prevalent, followed by traditional-stable and nontraditional-stable trajectories. Implications for gender intensification and cognitive-developmental approaches to masculinity attitudes are discussed.

Adolescents' reports of communication with their parents about sexually transmitted diseases and birth control: 1988, 1995, and 2002.

PURPOSE: We examine trends in adolescents' reports of discussion with parents about sexually transmitted diseases (STDs) and birth control methods from 1988 to 2002. METHODS: Data from the 1988 and 1995 National Survey of Adolescent Males, and the 1988, 1995, and 2002 National Survey of Family Growth were analyzed to evaluate changes in discussions of female adolescents with parents about birth control methods and STDs, and changes in male adolescent discussions with parents about birth control methods. The sample includes never married males and females aged 15-17 years. RESULTS: In 2002, fewer female adolescents reported discussion with a parent about STD or birth control methods than in 1995. The share of female adolescents in 2002 reporting no discussion of either topic with their parents increased by almost half compared to 1995. Patterns across time in male adolescents' discussions of birth control methods with their parents appear stable. CONCLUSIONS: The recent decline in female adolescent reports of parent-communication about birth control and STDs, and the increase in female adolescent reports of no discussion of either topic suggest that public health officials, educators, and clinicians should invigorate their efforts to encourage parents to talk with their children about STDs and birth control.

Women's perspectives on family planning service quality: an exploration of differences by race, ethnicity and language.

CONTEXT: Despite calls to make family planning services more responsive to the values, needs and preferences of clients, few studies have asked clients about their experiences or values, and most have used surveys framed by researchers', rather than clients', perspectives. METHODS: Forty in-depth interviews exploring lifetime experiences with and values regarding services were conducted with 18-36-year-old women who visited family planning clinics in the San Francisco Bay Area in 2007. Women were categorized as black, white, English- or Spanish-speaking Latina, or of mixed ethnicity to allow examination of differences by racial, ethnic and language group. Interviews were audiotaped, transcribed and coded thematically; matrices were then used to compare the themes that emerged across the subgroups. RESULTS: Eight themes emerged as important to women's views of services: service accessibility, information provision, attention to client comfort, providers' personalization of care, service organization, providers' empathy, technical quality of care and providers' respect for women's autonomy. Women reported that it was important to feel comfortable during visits, to feel that their decision-making autonomy was respected, to have providers show empathy and be nonjudgmental, and to see the same provider across visits. The only notable difference among racial, ethnic and language groups was that Spanish-speaking Latinas wanted to receive language-appropriate care and contraceptive information. CONCLUSIONS: Future surveys of family planning service quality should include measures of the factors that women value in such care, and efforts to improve providers' communication and counseling skills should emphasize the personalization of services and respect for clients' autonomy.

What are the consequences of relying upon self-reports of sexually transmitted diseases? Lessons learned about recanting in a longitudinal study.

PURPOSE: Self-reports are the standard measure of STD history used in survey research. We explored to what extent self-reports of ever having an STD are recanted in a follow-up data collection. METHODS: Using the National Survey of Adolescent Males (NSAM), we assessed consistency over time in self-reports of ever having an STD in a sample of young men transitioning from adolescence to young adulthood (aged 15-26 years), a population in which STDs are particularly prevalent. RESULTS: Approximately 7% of all sexually experienced young men rescinded STD self-reports over time. Thus, self-reports at one point in time likely underestimate true STD history, using earlier self-reports as the criterion. Among men who ever report an STD, 94-98% recant their reports in later waves. CONCLUSIONS: Knowledge of the extent of underreporting can potentially be used to adjust cross-sectional estimates of STDs based on survey self-reports. These study findings move us one step closer to estimating just how much underreporting of STDs in self-reports is.
