Correlates of Sexual Behavior Across Fatherhood Status: Finding From the National Longitudinal Study of Adolescent to Adult Health (Add Health), 2016-2018

Amid national trends in postponed parenthood and more diverse family structures, the fatherhood identity may be important to men's sexual behaviors. This study examined factors associated with reports of consistent contraceptive use and multiple sexual partners across fatherhood status. Using public data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), Wave V (2016-2018), two sexual behaviors were examined among 1,163 men aged 32 to 42 years. Outcomes were two binary indicators: consistent contraceptive use with partner and having multiple (≥2) sexual partners in the past year. Fatherhood status was categorized as nonfather, resident father, and nonresident father. Demographic (e.g., race/ethnicity, education, income, and relationship type) and health-related (e.g., drinking, perceived stress, depressive symptoms, and insurance status) factors were considered. Logistic regression analysis produced odds ratios and 95% confidence intervals and were stratified by fatherhood categories. In the sample, 72% of men were resident fathers, 10% were nonresident fathers, and 18% were nonfathers; 28% reported consistent contraceptive use and 16% reported multiple sexual partners. For nonfathers, relationship type and race were associated with reporting multiple sexual partners. For resident fathers, relationship type was the crucial factor associated with consistent contraceptive use and reporting multiple sexual partners. In nonresident fathers, relationship type, education, and income were important factors to consistent contraceptive use and reporting multiple sexual partners. Key findings suggest that relationship type, income, and education are crucial factors to men's sexual behavior. Heterogeneous effects were observed across fatherhood status. This study adds to limited research on fatherhood and sexual behavior among men transitioning from young adulthood to middle age.

The Patient Protection and Affordable Care Act and oral health care use among formerly incarcerated people in the United States

BACKGROUND

Formerly incarcerated people report less frequent oral health care use, despite having more substantial oral health problems. This study aimed to determine whether the adoption of the Patient Protection and Affordable Care Act (ACA) has improved oral health care use among formerly incarcerated people in the United States.

METHOD

Data were from Wave I (1994-1995), Wave IV (2008), and Wave V (2016-2018) of the National Longitudinal Study of Adolescent to Adult Health (n = 9,108), a nationally representative cohort study in the United States.

RESULTS

On the basis of the results of multiple logistic regression analysis with interaction terms, the authors found a positive and statistically significant interaction between prior incarceration and living in a state with ACA adoption on past-year oral health care use, net of potential confounding variables (incarceration × ACA: odds ratio, 1.587; 95% CI, 1.043 to 2.414). Substantively, the findings suggest that people with a history of incarceration are less likely to use oral health care, and this disparity is more likely to occur in states without ACA adoption.

CONCLUSIONS

ACA adoption corresponds with improvements in the receipt of oral health care among formerly incarcerated people.

PRACTICAL IMPLICATIONS

This study builds on prior evidence highlighting that the ACA is beneficial in connecting formerly incarcerated people to health care services and suggests that these benefits may extend to improving access to and use of oral health care.

Sex Work and Educational Mobility: Results from the National Longitudinal Study of Adolescent to Adult Health

The purpose of the study was to assess the relationship between sex work involvement and education mobility among a national sample of US young adults. Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health; N = 7732) were analyzed to explore the prospective association between lifetime sex work involvement measured in young adulthood (Wave III; ages 18-26) and educational mobility measured in adulthood (Wave V; ages 33-43). Multinomial logistic regression analyses were conducted, adjusting for relevant demographic and control variables. Results indicated that young adults who reported ever having been paid for sex by the ages of 18-26 had twofold greater risk (95% confidence interval 1.26-3.18) of having downward educational mobility compared to a stable level of education, or the same education, relative to their parents in adulthood. Given that education, by means of regular social connectedness to social supports, may be the most salient resiliency factor protecting adolescents from potential risks associated with sex work involvement (e.g., stigma, isolation from services), the findings from this study support the promotion of inclusive engagement from school settings to foster educational attainment and prevent poorer health and psychosocial outcomes that research to date has associated with sex work involvement.

Children of immigrants: Racial assortative mating and the transition to adulthood

Few studies have followed immigrant-origin individuals from adolescence to adulthood or examined their spousal choices. Using longitudinal data from Add Health, we present a life-course model that examines the differences in racial assortative mating between children of immigrants and non-immigrants. The results reveal substantial variation in racial endogamy from generation to generation. Racial endogamy was highest in the third generation, but this is due entirely to high racial endogamy among whites. Out-marriage was most pronounced among first- and second-generation immigrants. Our life-course approach shows that the effects of race and generation on intermarriage were mediated by family background (e.g. language proficiency and residence) and educational attainment (at time of marriage), a finding largely indicative of processes of marital assimilation that unfold over time and generation. Evidence of acculturation and structural assimilation, however, could not fully account for the large, persistent, and uneven effects of race and generation on interracial marriage.

To Make and Keep Friends: The Role of Health Status in Adolescent Network Tie Formation and Persistence

Health status may shape network structure through network dynamics (tie formation and persistence) and direction (sent and received ties), net of typical network processes. We apply Separable Temporal Exponential Random Graph Models (STERGMs) to National Longitudinal Study of Adolescent to Adult Health survey data (n = 1,779) to differentiate how health status shapes network sent and received tie formation and persistence. Results indicate that networks are shaped by withdrawal of adolescents experiencing poor health, highlighting the importance of separating distinct and directed processes of friendship formation and persistence when considering how health relates to adolescent social life.

Testing Environmental Effects on Age at Menarche and Sexual Debut within a Genetically Informative Twin Design

Life-history-derived models of female sexual development propose menarche timing as a key regulatory mechanism driving subsequent sexual behavior. The current research utilized a twin subsample of the National Longitudinal Study of Adolescent to Adult Health (Add Health; n = 514) to evaluate environmental effects on timings of menarche and sexual debut, as well as address potential confounding of these effects within a genetically informative design. Results show mixed support for each life history model and provide little evidence rearing environment is important in the etiology of individual differences in age at menarche. This research calls into question the underlying assumptions of life-history-derived models of sexual development and highlights the need for more behavior genetic research in this area.

One of these things is not like the other: Predictors of core and capital mentoring in adolescence

Informal mentoring has many demonstrated impacts on young people, including increased educational attainment, economic mobility, and both physical and mental health. Emerging work on a typology within informal mentoring suggests that "core" mentors are often extended family members and provide emotional support, while "capital" mentors are connected to formal institutions and provide valued advice and social capital. The present paper contributes to this emerging body of work by examining which qualities of a young person and their environment lead to core versus capital mentoring using a nationally representative sample of youth (N = 4226). Using both a series of regression analyses and conditional inference trees, findings demonstrate the importance of racial-ethnic identity and socioeconomic status. Peabody Picture Vocabulary score, a likely indicator of socioeconomic resources, was consistently a robust indicator of capital mentoring. Implications for both practice and research are discussed.

Race and Ethnicity, Racism, and Population Health in the United States: The Straightforward, the Complex, Innovations, and the Future

For far too long, U.S. racialized groups have experienced human suffering and loss of life far too often and early. Thus, it is critical that the population sciences community does its part to improve the science, education, and policy in this area of study and help to eliminate ethnoracial disparities in population health. My 2022 PAA Presidential Address focuses on race and ethnicity, racism, and U.S. population health in the United States and is organized into five sections. First, I provide a descriptive overview of ethnoracial disparities in U.S. population health. Second, I emphasize the often overlooked scientific value of such descriptive work and demonstrate how such seemingly straightforward description is complicated by issues of population heterogeneity, time and space, and the complexity of human health. Third, I make the case that the population sciences have generally been far too slow in incorporating the role of racism into explanations for ethnoracial health disparities and lay out a conceptual framework for doing so. Fourth, I discuss how my research team is designing, collecting, and disseminating data for the scientific community that will have potential to, among many other purposes, create a better understanding of ethnoracial health disparities and the role of racism in producing such disparities. Finally, I close by suggesting some policy- and education-related efforts that are needed to address racism and population health within U.S. institutions.

Estimating the Long-Term Causal Effects of Attending Historically Black Colleges or Universities on Depressive Symptoms

Racism is embedded in society, and higher education is an important structure for patterning economic and health outcomes. Historically Black Colleges and Universities (HBCUs) were founded on antiracism while predominantly White institutions (PWIs) were often founded on white supremacy. This contrast provides an opportunity to study the association between structural racism and health among Black Americans. We used the National Longitudinal Study of Adolescent to Adult Health (Add Health) to estimate the long-term causal effect of attending an HBCU (vs. PWI) on depressive symptoms among Black students in the United States from 1994-2018. While we found no overall association with attending an HBCU (vs. PWI) on depressive symptoms, we found that this association varied by baseline mental health and region, and across time. For example, among those who attended high school outside of the South, HBCU attendance was protective against depressive symptoms 7 years later, and the association was strongest for those with higher baseline depressive symptoms. We recommend equitable state and federal funding for HBCUs, and that PWIs implement and evaluate antiracist policies to improve mental health of Black students.

The Immigrant Experience and Alcohol Use: Heart Rate as a Source of Risk and Resilience

The immigration experience in the USA has been linked to a wide range of behavioral and physical outcomes. Studies report that immigrants, relative to native-born citizens, are less likely to develop alcohol use habits despite facing hardship during the acculturation process. Limited research, however, has examined whether and to what extent resting heart rate (RHR) plays a role in accounting for individual differences in the acculturation process in the USA. To begin to address this gap in research, cross-sectional self-report data (N = 4775) from a nationally representative sample of US adults are analyzed to examine the association between the immigrant experience, alcohol use, and drunkenness. The role of low, mean, and high RHR on this association is investigated. The results reveal that respondents with higher levels of the immigrant experience report lower levels of alcohol use and drunkenness. RHR partially conditions the relationship between the immigrant experience and alcohol use, whereby respondents with higher levels of the immigrant experience and high RHR report less alcohol use and drunkenness, compared to more native respondents with low RHR. Immigrant experience and alcohol use were associated, but not with drunkenness among respondents with average RHR levels, relative to those with low RHR levels. The results suggest that RHR may be a potential source of both risk for and resilience to the development of alcohol use behaviors among immigrants going through the acculturation process in the USA.

Involvement in Crime and Delinquency and the Development of Technological and Computer Skills: A Longitudinal Analysis

A body of research has revealed that involvement in crime and delinquency is associated with a wide number of social, economic, and health consequences. The current study built off this knowledge base and examined whether measures of adolescent violent delinquency and contact with the criminal justice system were related to the access of basic, and experience with, technology, and computers. To do so, longitudinal data drawn from the National Longitudinal Study of Adolescent to Adult Health (Add Health) were analyzed. The results revealed that self-reported violent delinquency in adolescence was associated with a decreased probability of owning a computer and having an email account 10 to 12 years into the future. Additionally, measures of contact with the criminal justice system, low self-control, delinquent peers, and governmental public assistance were also associated with the probability of owning a computer and having an email account.

Commercial Sexual Exploitation Outcomes in a Community Sample of Youth

PURPOSE

Researchers have suggested that victims of commercial sexual exploitation (CSE) have deleterious long-term outcomes; however, longitudinal trajectories of youth who experience CSE have not been explored. For the current study, the National Longitudinal Study of Adolescent to Adults Health (Add Health) survey was used to compare trajectories of youth who had experienced CSE with their nonexploited peers.

METHODS

Propensity score matching was used to match youth at waves 1 and 2 who experienced CSE and who did not experience CSE but had similar risk profiles. Youth with low-risk profiles were also matched. Our sample included 430 youth who experienced CSE, a matched sample of 430 youth who did not experience CSE but had a similar risk profile, and a sample of youth who did not experience CSE and had low-risk profiles (n = 782). Outcomes of interest included psychological, behavioral, physical, and interpersonal well-being.

RESULTS

Youth who had experienced CSE had higher levels of injection drug use, more police stops, more emergency room visits, and lower relationship satisfaction than their nonexploited peers. Well-being for individuals who experienced CSE as youth changed some over time, but those changes were comparable to the changes experienced by individuals of similar risk who did not experience CSE. Well-being measures for low-risk youth were universally higher compared to high-risk youth, regardless of CSE.

DISCUSSION

Youth receiving drug treatment, experiencing delinquency, or being seen in emergency medical settings may benefit from CSE screening, so that victims can be identified and provided immediate and comprehensive services.

Risk of Food Insecurity in Young Adulthood and Longitudinal Changes in Cardiometabolic Health: Evidence from the National Longitudinal Study of Adolescent to Adult Health

BACKGROUND

Studies have demonstrated relations between food insecurity, the lack of access to enough nutritious food, and greater risk of diet-sensitive chronic diseases. However, most prior evidence relies on cross-sectional studies and self-reported disease.

OBJECTIVES

The objective was to assess the longitudinal relation between risk of food insecurity in young adulthood and changes in diet-sensitive cardiometabolic health outcomes across 10 y among non-Hispanic white, non-Hispanic black, American Indian or Alaska Native, and Hispanic adults.

METHODS

Data from the fourth and fifth waves (n = 3992) of the National Longitudinal Study of Adolescent to Adult Health were used. Measures included risk of food insecurity, body weight, diabetes, and sociodemographic characteristics. Body weight and diabetes were assessed with direct measures. Mixed-effects models assessed the association of risk of food insecurity with BMI, obesity, and diabetes while accounting for sociodemographic characteristics and the complex survey design.

RESULTS

Risk of food insecurity was associated with increases in BMI as well as incidence of obesity and diabetes from young to middle adulthood in unadjusted and adjusted models (all P < 0.01). In models stratified by race and ethnicity, the relations of risk of food insecurity with body weight outcomes and diabetes varied.

CONCLUSIONS

Risk of food insecurity in young adulthood was related to BMI and obesity during young and middle adulthood but not in changes over time. Risk of food insecurity in young adulthood related to an increased incidence of diabetes in middle adulthood. However, the relations among specific racial and ethnic groups were unclear. Estimates of the relation between food insecurity and cardiometabolic health outcomes within racial and ethnic groups experiencing the highest prevalence of these conditions should be refined.

Adolescent Delinquency and Adulthood Economic Disadvantage and Job Benefits: Results From a Longitudinal Sample of Males and Females

There is a long history of examining the connection between crime and delinquency and economic well-being and employment quality. Despite this vast literature, there still remains unanswered questions surrounding these associations, including whether the timing of adolescent delinquency is associated with adulthood economic disadvantage and job quality, whether different types of adolescent delinquency maintain differential associations with measures of economic disadvantage and employment quality in adulthood, and whether any associations between delinquency and economics/employment are invariant between males and females. The current study sought to address these issues by exploring the associations between adolescent involvement in nonviolent and violent delinquency (measured at two times in adolescence) and adulthood economic disadvantage and job quality. To do so, data drawn from the National Longitudinal Study of Adolescent to Adult Health were analyzed. The results revealed consistently null associations between the measures of adolescent delinquency and economic disadvantage and job quality for males. For females, however, the results were consistently significant, indicating that females who self-reported greater involvement in delinquency were more likely to be economically disadvantaged as adults and to have lower quality jobs. These results indicate that the associations between delinquency and economic disadvantage and job benefits differs between males and females, with females, in comparison with males, paying a significantly greater toll for engaging in acts of violent and nonviolent delinquency.

Does Self-control Predict Crime, Delinquency, and Victimization in Immigrants? A Longitudinal Analysis

Gottfredson and Hirschi's theory of low self-control has generated a considerable amount of research and the results of these studies have shown that low levels of self-control are consistently associated with involvement in antisocial outcomes. Despite the empirical support for this theory, there still remain areas of it that need to be more fully evaluated. Once such area is whether self-control is associated with antisocial outcomes in samples of immigrants. The current study sought to address this gap in the literature. To do so, data drawn from the National Longitudinal Study of Adolescent to Adult Health (Add Health) were analyzed. The results of the statistical models revealed that low levels of self-control were associated with increases in self-reported delinquency, being arrested, being convicted of a crime, being sentenced to probation, being incarcerated, and being victimized. Taken together, the results of this study show that self-control is a robust predictor of antisocial outcomes among immigrants. We conclude by identifying limitations of the current study and directions for future research.

A Gene-Environment Interaction Study of Polygenic Scores and Maltreatment on Childhood ADHD

This study explored whether maltreatment moderates the association of polygenic risk for ADHD. Because individuals with low polygenic scores (PGS) for ADHD were previously shown to have better than expected functional outcomes (i.e., cognitive, mental health, social-emotional) than individuals with middle or high ADHD PGS, we hypothesized low ADHD PGS may confer a protective effect from maltreatment in the development of ADHD. Data were from participants with phenotypic and genotypic data in the National Longitudinal Study of Adolescent to Adult Health (Add Health; n = 4,722). ADHD PGS were generated from the most recent genome-wide association study on ADHD and categorized into three groups (i.e., low, medium, high) using empirically determined cut-points. A maltreatment factor score was derived from five forms of self-reported maltreatment experiences prior to age 18. ADHD PGS and maltreatment were positively associated with ADHD symptoms, as expected. However, no interaction between ADHD PGS and maltreatment on ADHD symptoms was detected. Despite the increase in predictive power afforded by PGS, the lack of an interaction between ADHD PGS and maltreatment on ADHD symptoms converges with an emerging body of PGS studies that have also failed to detect PGS-environment interplay in mental disorders. We discuss possible reasons for this pattern of results and offer alternative methods for future research in understanding gene-environment interactions.

Examining the Potential Association Between Immigration and Criminal Involvement Using a Nationally Representative and Longitudinal Sample of Youth

There has been a great deal of debate regarding the association between immigration and criminal involvement. Against this backdrop, this study sought to make an incremental increase to the literature by examining the nexus between immigration and crime. To do so, data were drawn from the National Longitudinal Study of Adolescent to Adult Health (N = 7,622-8,334). The results of the multivariate regression models revealed no evidence that immigrants, in comparison with U.S. citizens, self-reported more involvement in nonviolent delinquency or violent delinquency. Where statistically significant effects did emerge, U.S. citizens reported greater involvement in these acts. Moreover, the analyses also did not provide any evidence that immigrants were more likely than U.S. citizens to report being arrested, pleading guilty, being sentenced to probation, or being incarcerated. Once again, U.S. citizens were significantly more likely to have contact with the criminal justice system when compared with immigrants. These results suggest that the potential link between immigration and crime is likely complex and is not a straightforward association. We conclude by discussing some of the implications of the findings and directions for future research.

Parents, Peers, and Trajectories of Cigarette Smoking: A Group-Based Approach

This study examines the independent, relative, and additive associations between both parent and peer role models and longitudinal patterns of smoking across adolescence and early adulthood. An analysis of data from the National Longitudinal Study of Adolescent to Adult Health (N=10,166) reveals at least four distinct trajectories of smoking across ages 13-35: (1) non-smokers; (2) late peak (almost 10 cigarettes per day around age 30); (3) an early peak group that reached roughly 10 cigarettes per day around age 20 and declined; and (4) a high group that increased during adolescence and early adulthood and then remained high. Parent and peer smoking behaviors were associated with trajectory group membership net of controls for sociodemographic characteristics, parental SES, parent-child relations, and the availability of cigarettes in the family home. Parents and peers appear to have at least some independent associations net of each other, but their combined effects are powerful.

Sexual Partner Accumulation From Adolescence to Early Adulthood in Populations With Physical Disabilities in the U.S

PURPOSE

This study aimed to examine the lifetime and pre-18 sexual partnering patterns of populations with physical disabilities from adolescence to early adulthood and how these patterns further vary by biological sex, race/ethnicity, and sexual orientation.

METHODS

Data were from 13,458 respondents to Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health. Poisson regression models were used to assess differences in pre-18 and lifetime sexual partner counts among populations with physical disabilities compared with those without disabilities. Moderation analyses by biological sex, race/ethnicity, and sexual orientation were used to consider further differences among minority subgroups.

RESULTS

The results indicated more similarities than differences in sexual partnering patterns across disability severity groups. Specifically, populations with disabilities had just as many pre-18 and lifetime sexual partners as peers without disabilities. There was variation by biological sex, race/ethnicity, and sexual orientation, although this was not tied to disability status.

CONCLUSIONS

These results fill an important gap in the literature by considering the sexual partnering behaviors of populations with physical disabilities in the U.S. over the life course. Future research should continue to include populations with disabilities and other minority groups to ensure that their experiences are represented in sexual health policies and programs.

Misuse of Prescription and Illicit Drugs in Middle Adulthood in the Context of the Opioid Epidemic

Background: The United States' opioid epidemic continues to escalate overdose deaths. Understanding its extent is complicated by concurrent misuse of other prescription or illicit drugs, increasing risk for overdose. Current surveillance using electronic medical records and police data has limitations and frequently fails to distinguish middle-aged adults from other age groups in reporting. Objectives: The purpose of this analysis is to (1) describe characteristics of middle-aged US adults who report misusing prescription and illicit drugs and (2) evaluate if misusing prescription opioids increases risk of misusing other drugs. Methods: We analyzed data from 12,300 adults ages 32-42 from Wave V of the Add Health study collected from 2016 to 2018. Self-reported past 30-day misuse of prescription sedatives, tranquilizers, stimulants, and opioids as well as cocaine, crystal methamphetamine, heroin, and other illicit drugs were analyzed for associations with demographic characteristics in weighted bivariate analysis and multivariable logistic regression. Results: Those misusing prescription opioids were more likely to misuse prescription sedatives, tranquilizers, and stimulants compared to those not misusing prescription opioids. Those misusing prescription opioids were also more likely to misuse heroin, crystal meth, cocaine, and other illicit drugs. Higher levels of education and personal income were protective for prescription opioid misuse, any prescription drug misuse, and any illicit drug misuse. Race/ethnicity was not significantly associated with prescription opioid misuse. Conclusions/Importance: Our analysis shows those misusing prescription opioids are at high risk of misusing other prescription and illicit drugs. Practitioners and researchers should consider concurrent drug misuse when treating and studying opioid misuse disorders.

Childhood polyvictimization and marijuana use trajectories

Despite public sentiment to the contrary, recreational marijuana use is deleterious to adolescent health and development. Prospective studies of marijuana use trajectories and their predictors are needed to differentiate risk profiles and inform intervention strategies. Using data on 15,960 participants in the National Longitudinal Study of Adolescent to Adult Health, variable-centered approaches were used to examine the impact of childhood polyvictimization on marijuana onset, marijuana use from age 15 to 24 years, and marijuana dependence symptoms. Zero-Inflated Poisson latent class growth analysis (ZIP-LCGA) was used to identify marijuana use subgroups, and their associations with childhood polyvictimization were tested via multinomial logit regression within ZIP-LCGA. Results showed that the overall probability and frequency of marijuana use increased throughout adolescence, peaked in early adulthood, and diminished gradually thereafter. Polyvictimization was associated with earlier onset and greater overall use, frequency of use, and dependence symptoms. ZIP-LCGA uncovered four subgroups, including non-users and three classes of users: adolescence-limited users, escalators, and chronic users. Polyvictimization distinguished non-users from all classes of marijuana users. The findings underscore the lasting developmental implications of significant childhood trauma. Children who experience polyvictimization represent a group that may benefit from selective interventions aimed at preventing early, frequent, chronic, and dependent marijuana use.

The intersection of individual differences, personality variation, & military service: A twin comparison design

In societies where military service is voluntary multiple factors are likely to affect the decision to enlist. Past research has produced evidence that a handful of personality and social factors seem to predict service in the military. However, recent quantitative genetic research has illustrated that enlistment in the military appears to be partially heritable and thus past research is potentially subject to genetic confounding. To assess the extent to which genetic confounding exists, the current study examined a wide range of individual-level factors using a subsample of twins (n = 1,232) from the restricted-use version of the National Longitudinal Study of Adolescent to Adult Health. The results of a series of longitudinal twin comparison models, which control for the latent sources of influence that cluster within families (i.e., shared genetic and family factors), illustrated generally null findings. However, individuals with higher scores on measures of extraversion and the general factor of personality were more likely to enlist in the military, after correction for familial confounding. Nonetheless, the overall results suggest that familial confounding should be a methodological concern in this area of research, and future work is encouraged to employ genetically informed methodologies in assessments of predictors of military enlistment.

Behavioral symptoms of eating disorders among adopted adolescents and young adults in the United States: Findings from the Add Health survey

OBJECTIVE

More adopted individuals report experiencing general psychopathology, poor parental attachment, and early childhood eating difficulties than nonadopted individuals, yet little is known about disordered eating in this population. This study sought to describe the relationship between adoption status and behavioral eating-disorder (ED) symptoms, and to examine potential correlates of ED symptoms that are unique to adopted individuals.

METHOD

We examined data from adolescents and young adults from Waves 1 (n adopted = 561, nonadopted = 20,184), 2 (n adopted = 211, nonadopted = 14,525), and 3 (n adopted = 416, nonadopted = 14,754) of the National Longitudinal Study of Adolescent to Adult Health. ED symptom items included dieting, breakfast skipping, binge eating, extreme weight loss behaviors (EWLBs; i.e., self-induced vomiting, laxative use, diet pill use) and lifetime ED diagnosis.

RESULTS

Compared to nonadopted individuals, adopted individuals were more likely to report EWLBs at Wave 2 and binge eating and lifetime ED diagnosis at Wave 3 (ps < .05). Among adopted individuals, contact with a biological parent was associated with higher rates of binge eating and lifetime ED diagnosis at Wave 3 (ps < .05), whereas age at adoption and having ever been in foster care were not associated with rates of ED symptoms.

DISCUSSION

This study provides preliminary evidence that being adopted may be a risk factor for certain behavioral symptoms of EDs. Given the benefits of early detection and treatment of ED symptoms, mental health professionals working with adopted individuals should assess for disordered eating.

Not only in my genes: The effects of peers' genotype on obesity

We use data from three waves of Add Health to study the short- and long-run effects of high school peers' genetic predisposition to high BMI-measured by grade-mates' average BMI polygenic scores-on adolescent and adult obesity in the U.S. We find that, in the short-run, a one standard deviation increase in peers' average BMI polygenic scores raises the probability of obesity for females by 2.8% points, about half the size of the effect induced by a one standard deviation increase in one's own polygenic score. No significant effect is found for males. In the long-run, however, the social-genetic effect fades away, while the effect of one's own genetic risk for BMI increases substantially. We suggest that mechanisms explaining the short-run effect for females include changes in nutrition habits and a distorted perception of body size.

Who Owns a Handgun? An Analysis of the Correlates of Handgun Ownership in Young Adulthood

Previous research on firearms has not adequately addressed a fundamental question about handgun ownership: Why do some people own handguns while most in the United States do not? We use data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine adolescent and adult correlates of handgun ownership, including socialization, victimization and fear of crime, political ideology, and societal insecurities. We also investigate the differences between "typical" owners and "atypical" owners who own more handguns. We find that socialization, victimization, conservatism, and societal insecurity all independently increase the likelihood of handgun ownership, and atypical handgun owners are more likely to be conservative and to have experienced victimization than typical owners.

Population-based RNA profiling in Add Health finds social disparities in inflammatory and antiviral gene regulation to emerge by young adulthood

Health in later life varies significantly by individual demographic characteristics such as age, sex, and race/ethnicity, as well as by social factors including socioeconomic status and geographic region. This study examined whether sociodemographic variations in the immune and inflammatory molecular underpinnings of chronic disease might emerge decades earlier in young adulthood. Using data from 1,069 young adults from the National Longitudinal Study of Adolescent to Adult Health (Add Health)-the largest nationally representative and ethnically diverse sample with peripheral blood transcriptome profiles-we analyzed variation in the expression of genes involved in inflammation and type I interferon (IFN) response as a function of individual demographic factors, sociodemographic conditions, and biobehavioral factors (smoking, drinking, and body mass index). Differential gene expression was most pronounced by sex, race/ethnicity, and body mass index (BMI), but transcriptome correlates were identified for every demographic dimension analyzed. Inflammation-related gene expression showed the most pronounced variation as a function of biobehavioral factors (BMI and smoking) whereas type I IFN-related transcripts varied most strongly as a function of individual demographic characteristics (sex and race/ethnicity). Bioinformatic analyses of transcription factor and immune-cell activation based on transcriptome-wide empirical differences identified additional effects of family poverty and geographic region. These results identify pervasive sociodemographic differences in immune-cell gene regulation that emerge by young adulthood and may help explain social disparities in the development of chronic illness and premature mortality at older ages.

The Association Between Genetic Predisposition and Parental Socialization: An Examination of Gene-Environment Correlations Using an Adoption-Based Design

An extensive body of research has examined the role that genetic influences play in the development of antisocial behavior. Even so, there remains much that is unknown regarding the intersections among antisocial behavior, environments, and genetic influences. The current study is designed to shed some light on this issue by examining whether gene-environment correlations are present in the lives of adopted adolescents. More specifically, this article seeks to contribute to scholarship efforts aimed at understanding whether biological parents' antisocial behavioral phenotypes-behaviors often attributed to an increased likelihood of receiving a genetic propensity for antisocial behaviors-predict variation in environments that are experienced by their adopted-away offspring. To do so, the biological parents of adoptees were assessed and used to identify ways in which children elicit certain responses from their adoptive parents based, in part, on their genotype. Correlational analyses were calculated on a sample of adoptees (the final analytic sample ranged between n = 229 and n = 293) drawn from the National Longitudinal Study of Adolescent to Adult Health (Add Health). The results of the study revealed very little evidence of gene-environment correlations. The implications of these findings are considered.

Fraternal Birth Order, Only-Child Status, and Sibling Sex Ratio Related to Sexual Orientation in the Add Health Data: A Re-analysis and Extended Findings

The fraternal birth order (FBO) effect related to men's sexual orientation refers to the finding that the number of older brothers that a man has increases his chance of being androphilic. The FBO effect has generally been well replicated in diverse samples; one instance of non-replication was by Francis (2008) using Waves I and III of the Add Health data. We attempted to replicate the FBO effect in the Add Health data taking into account family size and other limitations of Francis' (2008) analyses. Also, we examined other sibling characteristics related to the FBO effect: sibling sex ratio and only-child status. We used two subsamples from Waves I (n = 20,745) and IV (n = 15,701) of the Add Health data, consisting of adolescents who were followed longitudinally from 1994 to 1995 until 2008. Wave I data were used to compute numbers of younger and older brothers and sisters from household roster information. Wave IV information about sexual orientation identity was used. Analyses were conducted within men and within women. We found modest support for the FBO effect in men, but not in women, using the older brother odds ratio, logistic regression analyses, and sibling sex ratio, which provided the strongest support for FBO. We found that gynephilic/biphilic women, but not androphilic/biphilic men, were more likely to be only-children compared to androphilic women and gynephilic men, respectively. We discuss limitations of the Add Health data and purported mechanisms for the FBO effect in men and the only-child effect in women.

Beyond the Classroom: The Intergenerational Effect of Incarceration on Children's Academic and Nonacademic School-Related Outcomes in High School

The author uses strategic comparison regression and the Longitudinal Study of Adolescent to Adult Health (n = 11,767) to explore the effect of parental incarceration on academic and nonacademic outcomes in high school. This method compares youth whose parents were incarcerated before the outcomes are measured with those whose parents will be incarcerated after. The author examines most recent grades and a range of nonacademic outcomes, such as truancy, involvement in school activities, and suspension. Results indicate that the associations between parental incarceration and grades are largely accounted for by selection, but associations between parental incarceration and nonacademic processes persist. Maternal incarceration holds particular importance for behavioral outcomes (fighting and truancy), and paternal incarceration holds particular importance for behavioral, connectedness, and disciplinary outcomes. Researchers examining the intergenerational consequences of incarceration should examine school contexts beyond the classroom and explore the pathways through which this disadvantage occurs.

Examining the Association Between Personal Victimization in Adolescence and Intimate Partner Victimization in Adulthood

A large body of research has examined various issues related to repeat victimization, including potential risk factors and theoretical explanations. Despite the amount of studies dedicated to focusing on repeat victimization, there are some notable gaps in the literature. One particularly noteworthy omission in this research is whether there is a link between personal victimization in adolescence and intimate partner violence (IPV) victimization in adulthood. The current study sought to address this gap. To do so, data drawn from the National Longitudinal Study of Adolescent to Adult Health were analyzed. The results revealed a statistically significant and relatively consistent association between personal victimization in adolescence and IPV victimization in adulthood. This association was detected for both males and females, and it was detected even after controlling for low self-control (males and females) and being the perpetrator of IPV (males). We conclude by noting some of the implications of these findings, as well as limitations to the study that need to be addressed in the future.

Self-Esteem, Weight Status, and Trying to Lose Weight During Young Adulthood: The Roles of Sex and Ethnicity/Race

Objectives

This study sought to examine sex and ethnicity/race differences in the associations between self-esteem, weight status, and trying to lose weight among young adults in the United States.

Methods

Data were drawn from Wave III (2001/2002) of the US National Longitudinal Study of Adolescent to Adult Health (Add Health public-use sample). Body mass index (BMI) was measured during in-home visits. Weight-loss patterns, self-esteem, and sociodemographics were assessed via self-reports. Logistic regression models were fitted among 4,594 young adults who were aged 21.8 (SD=1.8) years.

Results

Obesity was associated with relatively poor self-esteem among both African American (P=.007) and White females (P<.006). In comparison to not trying to lose weight, trying to lose weight was associated with poorer self-esteem among normal-weight (OR=1.23, 95% CI=1.03-1.47) and overweight (OR=1.36, 95% CI=1.07-1.72) White females, but not among White females with obesity (OR=1.19, 95% CI=.92-1.55), African American females (OR=.81, 95% CI=.57-1.17), or males (OR=1.00, 95% CI=.88-1.14).

Conclusion

The decision to lose weight was linked with poor self-esteem solely among normal-weight and overweight White females. African American and White females with obesity presented with relatively poor self-esteem, but their decision to lose weight was not linked with their self-esteem. More studies are needed to understand the psychological mechanism behind the decision to lose weight among White females with obesity, African American females, and males.

Longitudinal Risks for Domestic Violence

Much research has examined the connections between victimization experiences in the family during childhood, adolescence, and adulthood. However, research that frames these different victimization experiences across the life course as part of a broader, longitudinal risk for experiencing domestic violence on the part of the individual, particularly within a theoretically driven model, is lacking. The current study uses data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a nationally representative sample of American adolescents, to examine how child abuse connects to victimization by dating partners during adolescence and victimization by romantic and marital partners during adulthood, and whether dating victimization mediates the relationship between child abuse and intimate partner victimization in adulthood. Results suggest that this is indeed the case, with child abuse having a direct effect on adolescent dating victimization and a direct and indirect effect on adult intimate partner victimization. Implications of the findings for theory and policy are discussed.

Welfare Participation in Childhood as a Predictor of Cigarette Use in Adulthood in the United States

OBJECTIVE

Smoking is widely acknowledged as a high-risk behavior associated with poor physical health outcomes. We use Add Health Wave I and Wave IV data (N = 15,701) to explore whether childhood welfare participation predicts smoking behaviors in adulthood.

METHOD

We conducted propensity score matching and dosage analysis of welfare participation to explore whether childhood welfare participation had different effects on smoking behaviors in adulthood. We used 3 approaches for dealing with the survey weight and propensity score weights for post-matching regression analyses.

RESULTS

Adults who as children lived in families that participated in welfare programs were more likely to smoke when compared to young adults whose families did not participate in welfare programs. Being from a smoking household, having smoked before adulthood, having peer smokers, and race/ethnicity increased the risk for smoking. Protective factors associated with decreased smoking behaviors included being female, higher parental education, and being older.

CONCLUSIONS

Risk related to cigarette use in adulthood varies based on welfare dosage in childhood. The development and implementation of interventions specific to subpopulations among welfare recipient families may make programs more effective.

Variations in the timing of first sexual experiences among populations with physical disabilities in the United States

BACKGROUND

Timing of first sex has important implications for later sexual health, but little research has considered this in populations with physical disabilities.

OBJECTIVE

The purpose of this paper was to examine timing of sexual experiences among populations with physical disabilities in the United States from adolescence to early adulthood, and how timing varies by biological sex, race/ethnicity, and sexual orientation. We hypothesized that those with physical disabilities would exhibit earlier initiation of each type of sexual activity compared to those without disabilities, but the degree of differences would depend on disability severity. We further hypothesized that these associations would be moderated by biological sex, race/ethnicity, and sexual orientation.

METHODS

Data were from 13,458 respondents to Waves I and IV of the National Longitudinal Study of Adolescent to Adult Health. Cox proportional hazards models assessed differences in timing of vaginal, oral, anal, and first sex by disability severity.

RESULTS

Populations with the most severe physical disabilities had a significantly slower progression to first vaginal sex, oral sex, and their first sexual experience compared to those without disabilities (aHR: 0.74-0.77). Timing also differed by biological sex, race/ethnicity, and sexual orientation, though the direction and degree of these differences varied by disability severity.

CONCLUSIONS

Results fill an important gap in the literature by considering variations in sexual timing among populations with physical disabilities using a longitudinal, nationally representative sample. Future research should continue to promote inclusion of populations with disabilities to inform future policies and programs for healthy sexual development.

The Influence of Parent and Parent-Adolescent Relationship Characteristics on Sexual Trajectories into Adulthood

To examine sexual partner acquisition into young adulthood and to explore what characteristics of the adolescent family context might predict this change, we used growth curve modeling to examine data from a nationally representative sample of adolescents followed longitudinally over 13 years through young adulthood (N = 5385). Growth curve modeling allowed us to treat the outcome as a dynamic variable and to examine 10 potential predictors of change while accounting for the nested nature of the data. Six family characteristics emerged as predictors of mean number of partners and rate of partner acquisition, while accounting for three significant adolescent predictors. Living in a single-parent or blended family and general communication about sex predicted higher lifetime number of sexual partners in young adulthood. Parent religiosity, parent disapproval of adolescent engagement in sex, and parent-adolescent connectedness were predictive of lower lifetime number of sexual partners. By following participants into their late twenties and early thirties, we were able to detect changes in the impact of early family factors that are not apparent in studies restricted to adolescents and emerging adults. For example, parent education, parent disapproval, and parent-adolescent connectedness were associated with higher rates of partner acquisition at age 23, but faster deceleration in partner acquisition as time progressed. Communication about negative consequences of sex was not predictive, regardless of whether it was "on time" (before sexual intercourse) or not. These results reveal that parents have significant, and sometimes unexpected, influence on their children's sexual behavior that persists well into adulthood.

Intermarriage and mother-child relationships

Research indicates that when adult children marry, ties to parents weaken. Yet less is known about how spousal characteristics, and specifically, spouse's race or ethnicity, affect ties to the family of origin. This paper uses data from the National Longitudinal Study of Adolescent to Adult Health to ask how interracial/ethnic marriage, compared to same-race/ethnicity marriage, is associated with ties to mothers among young adults in the United States. Results indicate that offspring who are intermarried differ little in their relationships to mothers compared to those who married same-race/ethnicity partners. However, findings from this study suggest that intermarriage may have greater consequences for some groups, such as Blacks, compared to other racial/ethnic groups. Overall, the results highlight how intermarriage has a relatively limited effect on offspring relationships with mothers and suggest a role for future research that examines how ties to parents during adolescence may shape partner choices during young adulthood.

Father Absence and Accelerated Reproductive Development in Non-Hispanic White Women in the United States

Girls who experience father absence in childhood also experience accelerated reproductive development in comparison with peers with present fathers. One hypothesis advanced to explain this empirical pattern is genetic confounding, wherein gene-environment correlation (rGE) causes a spurious relationship between father absence and reproductive timing. We test this hypothesis by constructing polygenic scores for age at menarche and first birth using recently available genome-wide association study results and molecular genetic data on a sample of non-Hispanic white females from the National Longitudinal Study of Adolescent to Adult Health. We find that young women's accelerated menarche polygenic scores are unrelated to their exposure to father absence. In contrast, polygenic scores for earlier age at first birth tend to be higher in young women raised in homes with absent fathers. Nevertheless, father absence and the polygenic scores independently and additively predict reproductive timing. We find no evidence in support of the rGE hypothesis for accelerated menarche and only limited evidence in support of the rGE hypothesis for earlier age at first birth.

Comparing cumulative index and factor analytic approaches to measuring maltreatment in the National Longitudinal Study of Adolescent to Adult Health

Child maltreatment is a complex and multifaceted construct in need of advanced statistical techniques to improve its measurement. The current study compared the predictive utility of a cumulative index to a factor analytic approach for constructing a measure of maltreatment. Data were from Waves III and IV of the National Longitudinal Study of Adolescent to Adult Health (Wave III: n = 14,800; Wave IV: n = 12,288). As adults, participants retrospectively reported on their childhood experiences of physical abuse, sexual abuse, emotional abuse, physical neglect, supervisory neglect, and social services investigations. Both the cumulative index and a two-factor solution showed evidence of convergent validity, predicting lifetime incidence of homelessness, being paid for sex, and various measures of running away or living apart from biological parents, and prospectively predicting depression, substance use, and criminal behavior. The latent variables, derived from a factor analytic approach, had greater explanatory power for many outcomes compared to the cumulative index, even when controlling for sociodemographic variables. Results suggest that factor analysis is a better methodology than a cumulative index for measuring maltreatment in large datasets when explanatory power for external outcomes is of greatest concern.

Exploring the relationship between welfare participation in childhood and depression in adulthood in the United States

OBJECTIVE

Depression is a serious mental health disorder, and untangling its causal agents is a major public health priority in the United States. This study examines the relationship between participating in welfare programs during childhood and experiencing depression during young adulthood.

METHOD

This study used wave I and IV data from the Add Health (N = 15,701). Multiple imputation is used to deal with missing data. Propensity score matching is used to reduce the selection bias, and then multiple regressions were used to examine the welfare participation and depression relationships.

RESULTS

Overall, young adults from welfare-recipient families reported significantly higher depression scores, rather than the clinical diagnosis of depression. Subgroup analyses showed only the poor group had significantly higher depression scores, whereas only the near-poor group had a significantly diagnosed depression outcome. Additionally, significantly higher depression scores were found for female youth from welfare-recipient families. However, no significant differences were found between the gender groups regarding diagnosed depression.

DISCUSSION

Using welfare participation as an economic marker, the subgroup analyses help to identify target populations for future intervention. Implications of this study will be of interest to policy makers and have value for informing policy decisions.

Adolescent Fertility Attitudes and Childbearing in Early Adulthood

Teens' attitudes about adolescent childbearing predict childbearing in the short term. If these attitudes reflect persistent goals and values, they may also be linked to later outcomes. To test long-term linkages, we analyze the association of adolescent fertility attitudes with actual and prospective fertility in adulthood using Waves I (1994-95) and IV (2007-08) of the National Longitudinal Study of Adolescent to Adult Health and focusing on men (N = 4,275) and women (N=4,418) without a teen birth. For women, we find that more negative teen attitudes predict lower hazards of a first birth up to around age 30 but that teens' attitudes are unrelated to planned childlessness among those who have not yet had children. Men's adolescent attitudes are unrelated to actual fertility or prospective intentions. For both men and women, more advantaged individuals are less likely to have had a child by around age 30; socioeconomic advantage is also related to postponement of childbearing rather than planned childlessness, though more so for women than men. We interpret the findings as evidence that, for girls, teens' attitudes toward adolescent childbearing capture an internalization of social schema about childbearing, childrearing, and sequencing with other life outcomes but do not reflect overall preferences about having children. More work is needed to understand the psychosocial factors that influence men's fertility.

An Examination of the Importance of Strain in the Cannabis Gateway Effect

Gateway theory has been the source of much debate in both the research literature and public policy. Support for gateway sequencing has been mixed, especially in research that has considered the role of criminological variables in the etiology of substance use. For example, limited prior research has observed as important in gateway sequencing the effects of severe stressors. Data from the National Longitudinal Study of Adolescent to Adult Health are utilized to test gateway theory and examine whether severe stressors affect the relationship between frequency of cannabis use and later use of other illicit drugs (OIDs). Findings suggest that while frequency of cannabis use does increase the likelihood of later use of OIDs, this relationship may be the result of the common cause of experiencing severe stress. Implications of the findings are discussed.

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.

The More You Have, The More You Lose: Criminal Justice Involvement, Ascribed Socioeconomic Status, and Achieved SES

In the present study, we examine the relationship between involvement in the criminal justice system and achieved socioeconomic status (SES), as well as the moderating effect of ascribed SES. Using data from the National Longitudinal Study of Adolescent to Adult Health, we find a nonlinear relationship between criminal justice involvement and achieved SES, such that deeper involvement leads to increasingly negative consequences on achieved SES. Furthermore, those coming from the highest socioeconomic backgrounds are not "protected" from the deleterious consequences of system involvement, but instead experience the greatest declines in achieved SES relative to where they started. In contrast, the effect of criminal justice involvement for those from below average ascribed SES is not significant. Our findings reinforce how normal such experiences are for people with the fewest resources, and also how system involvement inevitably destroys human capital, undermines future life chances, and ultimately promotes a "rabble" class.

Have Mischievous Responders Misidentified Sexual Minority Youth Disparities in the National Longitudinal Study of Adolescent to Adult Health?

The National Longitudinal Study of Adolescent to Adult Health (Add Health) has been instrumental in identifying sexual minority youth health disparities. Recent commentary suggested that some Wave 1 youth responders, especially males, intentionally mismarked same-sex attraction and, as a result, published reports of health disparities from these data may be suspect. We use two recently developed approaches to identify "jokesters" and mischievous responding and apply them to the Add Health data. First, we show that Wave 1 same-sex attracted youth, including those who later reported completely heterosexual identities in adulthood, were no more likely than different-sex attracted youth and consistently heterosexual participants to be "jokesters." Second, after accounting for mischievous responses, we replicated six previously established disparities: depressive symptoms, suicidal ideation and behaviors, alcohol use, cocaine use, parental satisfaction, and school connectedness. Accounting for mischievousness resulted in the elimination of one observed disparity between heterosexual and sexual minority youth: suicidal ideation for males who reported romantic attraction to both sexes. Results also showed that accounting for mischievous responding may underestimate disparities for sexual minority youth, particularly females. Overall, results presented here support previous studies that identified health disparities among sexual minority youth using these data.

Experiences of Vaginal, Oral, and Anal Sex From Adolescence to Early Adulthood in Populations With Physical Disabilities

PURPOSE

Few studies have sought to understand the typical sexual development of populations with physical disabilities in the United States, and those that do are often based on convenience samples or cross-sectional data. The purpose of this paper is to examine relationships between physical disability and experiences of vaginal, oral, and anal sex in a nationally representative sample of individuals in the United States who have been followed from adolescence through early adulthood.

METHODS

We used data from 13,456 respondents who completed Waves I (1994-1995) and IV (2008-2009) of the National Longitudinal Study of Adolescent to Adult Health (Add Health). Physical disabilities were identified and grouped by severity using information regarding limb difficulties, blindness, and deafness during adolescence. Analyses included bivariate statistics and adjusted logistic regression models relating physical disability and experiences of each type of sex.

RESULTS

Respondents with the most severe physical disabilities had significantly lower odds of experiencing vaginal sex, oral sex, and having any sexual experience compared with the odds of those without disabilities. After stratifying by biological sex, we found that males with the most severe physical disabilities had significantly lower odds of experiencing any type of sex compared with the odds of males without disabilities, whereas females with moderate and severe physical disabilities had significantly lower odds of experiencing vaginal sex compared with the odds of females without disabilities.

CONCLUSIONS

Our findings build on past research often conducted with convenience samples or cross-sectional data, indicating variation in sexual experiences among populations with disabilities.

How Economic Disadvantage Affects the Availability and Nature of Mentoring Relationships During the Transition to Adulthood

Supportive nonparental adults, particularly nonfamilial adults, provide critical support during the transition to adulthood, opening doors to educational and career paths. This study examined whether economic disadvantage shapes access to these relationships. Results showed that low-income adolescents had reduced access to naturally occurring mentors, and the relationships they did form tended to be close bonds with family and friends, rather than nonfamilial adults. Their mentors were more likely to focus on practical support, and less likely to serve as role models or provide career advice. These effects of socioeconomic status on natural mentoring relationships remained evident, even when accounting for youth race/ethnicity. Findings suggest that networks of support differ depending on a youth's socioeconomic context in ways that could perpetuate social and economic inequalities.

The School Contextual Effect of Sexual Debut on Sexual Risk-Taking: A Joint Parameter Approach

BACKGROUND

Previous research has identified individual and school-level characteristics that are associated with sexual risk-taking, but the impact of school-level mechanisms on sexual risk-taking is not well understood. We examine the aggregated effects that early sex at the school level have on risky sexual behaviors.

METHODS

We use 3 waves of data from the National Longitudinal Study of Adolescent Health. An individual's first sexual intercourse before age 15 was recorded along with various risky sexual behaviors at debut. Two variables at respondent's later stage of life were also included: having sex in exchange for drugs or money, and contraction of sexually transmitted disease (STD). Longitudinal analysis was conducted using a joint parameter model that tested unobserved school effects on individual behaviors simultaneously.

RESULTS

An increase in early sexual initiation at the school level was associated with higher probability of sexual debut, along with increased involvement in sexual risk-taking controlling for student family background.

CONCLUSIONS

School behavioral mechanisms are directly related to sexual health behaviors among youth. Our findings have implications for school-based interventions, education programs, and the role of parents.

Identifying diverse life transition patterns from adolescence to young adulthood: The influence of early socioeconomic context

The purposes of the present study are to investigate: (1) the heterogeneity in life transition patterns of youth from adolescence to young adulthood (ages 18-30) involving the timing and sequence of four transition events (college graduation, full-time employment, marriage, and parenthood), (2) the influence of early socioeconomic adversity on life transition patterns from adolescence to young adulthood, and (3) the influence of gender and race/ethnicity on these transition patterns. Using a multivariate discrete-time mixture survival model with a sample of 14,503 adolescents from the National Longitudinal Study of Adolescent to Adult Health (Add Health), the study identified four life transition patterns and found that early socioeconomic adversity shapes disrupted life transition patterns from adolescence to young adulthood. Gender and race/ethnicity differences are discussed. These results highlight the need for prevention and intervention programs that selectively target at-risk youth beginning in adolescence and continuing through subsequent transition periods.

Household Financial Assets Inequity and Health Disparities Among Young Adults: Evidence from the National Longitudinal Study of Adolescent to Adult Health

INTRODUCTION

Research has established a strong relationship between financial resources and health outcomes. Yet, little is known about the effects of assets disparities on health outcomes, especially during the critical period when adolescents transition to adults. Methods: Using data from the National Longitudinal Study of Adolescent to Adult Health (n = 10,861), this study investigated the relationships between three household total assets value groups (low, moderate, and high assets) and three net worth groups (negative, neutral, and positive) on young adults' general health, obese, and depression.

RESULTS

Both assets and debts were related to young adults' health status, young adults with more assets and positive net worth have higher probability to report a better level of both general health and depression. Young adult's obesity was found to be associated with net worth but not with assets.

CONCLUSIONS AND IMPLICATIONS

Our work connects health promotion with poverty alleviation to address the challenge of health disparity. A better understanding of different forms of financial resources (e.g., income, assets, and debt) and their dynamic relationships with health outcomes will contribute to developing effective asset-based interventions for promoting health status. Particularly, current policy and practice should consider the importance of resolving and clearing debt.
