Selected AbstractsA REAPPRAISAL OF THE OVERLAP OF VIOLENT OFFENDERS AND VICTIMS,CRIMINOLOGY, Issue 4 2008CHRISTOPHER J. SCHRECK Because research shows a close association between offending and victimization, recent work has argued that theories that account for crime should explain victimization as well. The current study uses a new approach to examine the extent of the overlap between offenders who commit violent crime and victims of violence to determine whether it is worthwhile to pursue separate theories to account for these phenomena. Specifically, we take the statistical approach that Osgood and Schreck (2007) developed for analyzing specialization in violent versus property offending and apply it to analyzing tendencies to gravitate toward violent offending versus victimization. In doing so, we treat the differentiation into victim and offender roles as an individual-level latent variable while controlling for confounding between the likelihood that individuals will take either role in violent acts and their overall numbers of encounters with violence (as either offender or victim). Our purpose is to examine 1) whether significant differentiation can be observed between the tendency to be an offender versus the tendency to be a victim, 2) whether any such differential tendency is stable over time, and 3) if it is possible to predict whether individuals will tend toward violent offending versus victimization. Using two waves of data from the National Longitudinal Study of Adolescent Health to explore these objectives, we find significant and stable levels of differentiation between offenders and victims. Moreover, this differentiation is predictable with explanatory variables. [source] THE TIMING AND MECHANISMS OF THE OFFENDING-DEPRESSION LINK,CRIMINOLOGY, Issue 3 2007SONJA E. SIENNICK Why is juvenile delinquency associated with depression in young adulthood? One possibility is that delinquency interferes with socioeco-nomic attainment and disrupts entry into adult roles, perhaps because of official labeling processes or adolescent socialization into deviance, and these repercussions of delinquency lead to depression. Another possibility is that grown delinquents may show high levels of depression because they tend to offend in adulthood, and adult offenders tend to be depressed. I use data from the National Longitudinal Study of Adolescent Health to examine the timing and mechanisms of the offending-depression relationship. The results suggest that delinquency is negatively associated with later status attainment and that the status attainment deficits of grown delinquents are not fully explained by justice system contacts or by adolescent delinquent peer influence. A portion of the longitudinal delinquency-depression link is explained by the low levels of education of grown delinquents and by their involvement with the justice system. Still, young adult depression is more closely tied to recent offending than it is to juvenile delinquency, official labeling, or the status attainment consequences of delinquency. [source] RACE, FRIENDSHIP NETWORKS, AND VIOLENT DELINQUENCYCRIMINOLOGY, Issue 4 2006DANA L. HAYNIE Although a growing body of literature emphasizes the role of friendship networks and peer relations for youth involvement in violence and delinquency, little research has examined the role of friendship networks in understanding the varying involvement of different racial-ethnic groups in violence. Using data from approximately 13,000 respondents to the first two waves of the National Longitudinal Study of Adolescent Health (Add Health), we explore the ability of friendship networks to account for the differential rates of violence among racial-ethnic groups. In addition, we evaluate whether race moderates the degree to which friendship characteristics predict adolescent violence. Findings indicate significant differences in the structure and behavioral orientation of friendship networks across racial-ethnic identities. Moreover, incorporating characteristics of friendship networks into multivariate analyses accounts for greater involvement in violence among black and Hispanic youths. Network racial heterogeneity and friends' popularity also emerge as particular network characteristics that operate differently for black and white youth. [source] Gender differences in genetic and environmental influences on gambling: results from a sample of twins from the National Longitudinal Study of Adolescent HealthADDICTION, Issue 3 2010Kevin M. Beaver ABSTRACT Aims To examine the extent to which genetic factors and shared and non-shared environmental factors are implicated in the development of gambling behaviors and to examine whether there are gender differences in the genetic and environmental contributors to gambling behaviors. Design A genetically informative analysis was performed by using DeFries,Fulker (DF) analysis. Setting Analysis of secondary data drawn from the National Longitudinal Study of Adolescent Health (Add Health). Participants A total of 324 monozygotic (MZ) twins and 278 same-sex dizygotic (DZ) twins were included in the analysis. Of these twins, there were 150 male MZ twins, 144 male DZ twins, 174 female MZ twins and 134 female DZ twins. Measurements Gambling behavior was measured through eight self-reported questions that tapped a range of items designed to measure problems related to gambling. Self-reported measures of self-control and delinquent involvement were also included to examine the degree to which these factors covaried with gambling behavior. Findings The results of the DF analysis indicated that when male and female twin pairs were analyzed simultaneously, genetic factors explained approximately 70% of the variance in gambling and non-shared environmental factors explained the remaining variance. When gender-specific models were calculated, substantial gender differences emerged. For males, genetic factors explained approximately 85% of the variance in gambling, with the non-shared environment accounting for the remaining variance. For females, genetic factors explained none of the variance in gambling behaviors, while the shared environment explained 45% of the variance and the non-shared environment explained 55% of the variance. Conclusions Analysis of twins from the Add Health data suggests that there are significant gender differences in the genetic and environmental underpinnings to gambling behaviors. [source] Romantic Relationships among Immigrant Adolescents1INTERNATIONAL MIGRATION REVIEW, Issue 2 2007Rosalind Berkowitz King We examine the importance of the family and friendship group as two crucial developmental contexts for adolescent relationship experiences. We focus particularly on immigrant adolescents who make up an increasing proportion of the youth population and who come from cultural contexts with stronger family traditions than native-born adolescents. Using data from the National Longitudinal Study of Adolescent Health, we model the characteristics associated with having romantic relationships and participating in sex-related activities within relationships for immigrant adolescents, children of immigrants and adolescents in native-born families. First generation adolescents are less likely to enter romantic relationships than adolescents in native-born families, but those who do participate engage in similar sex-related activities as native-born youth. This evidence suggests that immigrant youth who enter romantic relationships are selective of the more assimilated to native adolescent norms of heterosexual behavior. The peer group is especially important for immigrant adolescents because it provides opportunities for romantic relationship involvement.

Using data from the National Longitudinal Study of Adolescent Health (Add Health), we used a person-oriented analysis to categorize young men according to patterns of adolescent religious involvement. Youth indentified as "highly religious evangelical" are more likely to enlist in the military compared to their "highly religious nonevangelical" and "nonreligious" counterparts; however, these findings hold only for those young men without college experience. These findings are discussed along with study limitations and promising directions for future research. [source] Catholic Schooling, Protestant Schooling, and Religious Commitment in Young AdulthoodJOURNAL FOR THE SCIENTIFIC STUDY OF RELIGION, Issue 2 2009Jeremy E. Uecker If and how Catholic and Protestant schools influence the religious lives of their students once they have graduated is unclear. Methodological limitations and inconsistencies in previous studies have resulted in confusing and often contradictory findings. Using data from two waves of the National Longitudinal Study of Adolescent Health (N,= 11,212), I compare the religious lives of young adults who attended Catholic, Protestant, and secular schools as adolescents. The results suggest that Protestant schoolers are far more religious as young adults than those who attended a secular school, a difference that is at least partially explained by the schools' religious environment. But young adults who attended Catholic schools report levels of religiosity that are similar to those educated in a secular school, and are actually lower for some outcomes. Studies of religious schoolers that ignore the religious tradition of the school overlook these differing effects and forfeit statistical explanatory power. [source] Cross-sectional study of violence in emerging adulthoodAGGRESSIVE BEHAVIOR, Issue 2 2009Robert F. MarcusArticle first published online: 9 DEC 200 Abstract Theories of emerging adulthood, the evolutionary perspective, and the presence of turning points in the lives of 19,25-year olds were examined in relation to serious perpetrated violence for a cross-sectional sample of men and women (n=14,098) from the National Longitudinal Study of Adolescent Health (Add Health), Wave III. Perpetrated, self-reported violence included armed robbery, gang fighting, using a weapon in a fight, pulling a knife or gun on someone, or shooting or stabbing someone. Results showed that 11.3% of emergent adults had perpetrated at least one of these behaviors in the past year. Hierarchical logistic regression analysis partially supported the three theories for both men and women, beyond the contribution of violence in adolescence. The presence of Wave III violence was more likely given the unique contributions of unmarried status and economic risk. Moreover, and consistent with the theory of emerging adulthood, both sensation seeking and depression declined with age and contributed to the acknowledgement of Wave III violence, beyond the contribution of controls for Wave I violence (6 years earlier), demographics, age, gender, unmarried status, and economic risk. Findings of age-related declines and gender differences in prevalence rates were consistent with previous research on nationally representative samples, and with the predictions of the three theories.

[source] Race/Ethnic Differences in Effects of Family Instability on Adolescents' Risk BehaviorJOURNAL OF MARRIAGE AND FAMILY, Issue 2 2010Paula Fomby We used data from the National Longitudinal Study of Adolescent Health (N = 7,686) to determine whether racial and ethnic differences in socioeconomic stress and social protection explained group differences in the association between family structure instability and three risk behaviors for White, Black, and Mexican American adolescents: delinquent behavior, age at first nonmarital sex, and age at first nonmarital birth. The positive association between mothers' union transitions and each outcome for White adolescents was attenuated by social protection. The association of instability with age at first sex and first nonmarital birth was weaker for Black adolescents but not for Mexican American adolescents. The weaker association was explained by Black adolescents' more frequent exposure to socioeconomic stress in the context of union instability. [source] Intimate Partner Violence in Young Adult Dating, Cohabitating, and Married Drinking PartnershipsJOURNAL OF MARRIAGE AND FAMILY, Issue 2 2010Jacquelyn D. Wiersma Using data from the National Longitudinal Study of Adolescent Health, this study examined intimate partner violence (IPV) and drinking partnerships in 741 young adults in male-female dating, cohabitating, and married relationships. Cluster analyses revealed four similar kinds of drinking partnerships: (a) congruent light and infrequent, (b) discrepant male heavy and frequent, (c) discrepant female heavy and infrequent, and (d) congruent moderate/heavy-frequent drinkers. Overall, there were no significant main effect differences across relationship type and clusters. The type of relationship and the type of drinking partnership interacted with contexts examined (i.e., type of violence severity, gender, and whether the violence was perpetration or victimization). Given the severity of IPV in couple relationships, additional empirical attention to drinking partnerships is warranted. [source] Stepfamily Formation: Implications for Adolescent Ties to Mothers, Nonresident Fathers, and StepfathersJOURNAL OF MARRIAGE AND FAMILY, Issue 4 2009Valarie King This study examines how the entrance of a stepfather influences adolescent ties to mothers and nonresident fathers and how prior ties to each biological parent influence the development of stepfather-stepchild ties. Data come from 1,753 adolescents in the National Longitudinal Study of Adolescent Health who lived with a single mother in Wave 1 who remained single, cohabited, or married by Wave 2, approximately 1 year later. Stepfamily formation had little consequence for adolescent-nonresident father ties. Adolescent-mother closeness, however, declined when cohabiting, but not married, stepfathers entered the household. Close ties to married stepfathers were more likely to develop when adolescents were closer to their mothers before stepfather entry. Prior ties to nonresident fathers were unrelated to stepfather-stepchild ties. [source] Religion, Pledging, and the Premarital Sexual Behavior of Married Young AdultsJOURNAL OF MARRIAGE AND FAMILY, Issue 3 2008Jeremy E. Uecker Social scientists know little about the effect of religion and abstinence pledging on premarital sex beyond adolescence. Evidence from a sample of married young adults in the National Longitudinal Study of Adolescent Health (N = 2,079) reveals that premarital sex is widespread even among religious Americans and abstinence pledgers. Nevertheless, these individuals are much more likely than their counterparts to avoid premarital sex entirely. When they do have premarital sex, pledgers are more likely to restrict the behavior to their future spouse. Though contextual, exposure, and social control effects explain some of the influence of religion and abstinence pledging, religion and abstinence pledging appear to exert robust, direct effects on premarital sexual behavior. [source] Parents' Union Dissolution and Adolescents' School Performance: Comparing Methodological ApproachesJOURNAL OF MARRIAGE AND FAMILY, Issue 3 2007Michelle L. Frisco We use data from the National Longitudinal Study of Adolescent Health and the Adolescent Health and Academic Achievement Study to estimate how parents' union dissolution influences changes in adolescents' mathematics course work gains, overall grade point average, and course failure rates during a window of approximately 1 year (N =2,629). A primary purpose of this study is demonstrating the utility of propensity score matching techniques for studying topics such as ours that pose methodological challenges such as dealing with endogeneity and selection bias. We compare propensity score matching techniques to ordinary least squares (OLS) regression methods to show and discuss comparability of results obtained using these different procedures. Findings suggest that associations between parents' union dissolution and achievement may be causal, regardless of method used. [source] Race/Ethnic Differences in the Marital Expectations of Adolescents: The Role of Romantic RelationshipsJOURNAL OF MARRIAGE AND FAMILY, Issue 3 2005Sarah R. Crissey I use a sample of 12,973 adolescents in the National Longitudinal Study of Adolescent Health (Add Health) to examine race/ethnic differences in perception of the likelihood of marriage in adulthood and the role of heterosexual romantic relationship experience in explaining this difference. Compared to adolescents from other race/ethnic backgrounds, White adolescents are more likely to date and are especially more likely than Black adolescents to participate in serious romantic relationships that increase marital expectations. Although the type of current or recent relationship is associated with marital expectations, they do not explain the observed race/ethnic gap in these expectations. Overall, the results suggest that these adolescent romantic experiences likely play only a small role in determining differential marital expectations. [source] Cumulative Environmental Risk and Youth Problem BehaviorJOURNAL OF MARRIAGE AND FAMILY, Issue 3 2004Jean M. Gerard Using data from Wave 1 (n = 5,070) and Wave 2 (n = 4,404) of the National Longitudinal Study of Adolescent Health, we examined the relationship between cumulative risk exposure and youth problem behavior. Cross-sectional analyses revealed a positive, linear association between cumulative risk and problem behaviors. The association between cumulative risk and externalizing problems was stronger for White youth than for Black youth. The association between cumulative risk and internalizing problems was stronger for girls than for boys, and stronger for White youth than for Black and Hispanic youth. Cumulative risk predicted change over time in internalizing problems. Findings support the theoretical notion that adolescents experience diminished psychological comfort when risk factors are present across several social domains. [source] Does sex education affect adolescent sexual behaviors and health?JOURNAL OF POLICY ANALYSIS AND MANAGEMENT, Issue 4 2006Joseph J. SabiaArticle first published online: 6 SEP 200 This study examines whether offering sex education to young teenagers affects several measures of adolescent sexual behavior and health: virginity status, contraceptive use, frequency of intercourse, likelihood of pregnancy, and probability of contracting a sexually transmitted disease. Using data from the National Longitudinal Study of Adolescent Health, I find that while sex education is associated with adverse health outcomes, there is little evidence of a causal link after controlling for unobserved heterogeneity via fixed effects and instrumental variables. These findings suggest that those on each side of the ideological debate over sex education are, in a sense, both correct and mistaken. Opponents are correct in observing that sex education is associated with adverse health outcomes, but are generally incorrect in interpreting this relationship causally. Proponents are generally correct in claiming that sex education does not encourage risky sexual activity, but are incorrect in asserting that investments in typical schoolbased sex education programs produce measurable health benefits. © 2006 by the Association for Public Policy Analysis and Management [source] Does early adolescent sex cause depressive symptoms?JOURNAL OF POLICY ANALYSIS AND MANAGEMENT, Issue 4 2006Joseph J. Sabia A recent study by the Heritage Foundation (Rector, Johnson, & Noyes, 2003) found evidence of a positive relationship between early sexual intercourse and depressive symptoms. This finding has been used to bolster support for funding abstinenceonly sex education. However, promoting abstinence will only yield mental health benefits if there is a causal link between sexual intercourse and depression. Using the National Longitudinal Study of Adolescent Health (Add Health), I carefully examine the relationship between early teen sex and several measures of depression. Controlling for a wide set of individuallevel and familylevel observable characteristics, crosssection estimates consistently show a significant positive relationship between early sexual activity for females and three measures of adverse mental health: selfreported depression, a belief that one's life is not worth living, and serious thoughts of suicide. However, differenceindifference estimates reflect no evidence of a significant relationship between early teen sex and depressive symptoms. These findings suggest that the positive association observed by Rector et al. (2003) can be explained by unmeasured heterogeneity. Thus, promoting abstinence among adolescents is unlikely to alleviate depressive symptoms.© 2006 by the Association for Public Policy Analysis and Management. [source] Longitudinal Associations Between Alcohol Problems and Depressive Symptoms: Early Adolescence Through Early AdulthoodALCOHOLISM, Issue 1 2009Naomi R. Marmorstein Background:, Alcohol use-related problems and depressive symptoms are clearly associated with each other, but results regarding the nature of this association have been inconsistent. In addition, the possible moderating effects of age and gender have not been comprehensively examined. The goals of this study were to clarify: (i) how depressive symptoms affect the levels and trajectory of alcohol use-related problems, (ii) how alcohol use-related problems affect the levels and trajectory of depressive symptoms, and (iii) whether there are differences in these associations at different points in development or between males and females. Methods:, Participants for this study were drawn from the National Longitudinal Study of Adolescent Health (AddHealth) data set, a community-based sample of 20,728 adolescents followed from adolescence through early adulthood. Multilevel models were used to assess how each problem affected the level and rate of change in the other problem over time; gender was considered as a possible moderator of these associations. Results:, The results indicated that alcohol use-related problems and depressive symptoms had reciprocal, positive associations with each other during the period from early adolescence through early adulthood; however, these effects differed somewhat by gender and age. High levels of depressive symptoms were associated with higher initial levels of alcohol problems (particularly among females), as well as faster increases in alcohol problems over time among males. High levels of alcohol problems were associated with higher initial levels of depressive symptoms (particularly among females), as well as less curvature in the slope of depressive symptoms so that although there was a large difference between people with high and low depressive symptoms in early adolescence, by early adulthood the difference was smaller (particularly among females). Conclusions:, These results highlight the importance of examining gender and age in studies on the associations between affective disorders and substance use disorders. [source] A Multilevel Analysis of Gender Differences in Psychological Distress Over TimeJOURNAL OF RESEARCH ON ADOLESCENCE, Issue 2 2009Amanda L. Botticello Females have higher rates of depression than males, a disparity that emerges in adolescence and persists into adulthood. This study uses hierarchical linear modeling to assess the effects of school context on gender differences in depressive symptoms among adolescents based on two waves of data from the National Longitudinal Study of Adolescent Health (N=9,709 teens, 127 schools). Analysis indicates significant school-level variation in both overall symptom levels and the average gender gap in depression net of prior symptoms and individual-level covariates. Aggregate levels of depressive symptomatology were positively associated with contextual-level socioeconomic status (SES) disadvantage. A cross-level contingency emerged for the relationship between gender and depressive symptoms with school SES and aggregate perceived community safety such that the gender "gap" was most apparent in contexts characterized by low SES disadvantage and high levels of perceived safety. These results highlight the importance of context to understanding the development of mental health disparities. [source] The Sexual Debut of Girls in Early Adolescence: The Intersection of Race, Pubertal Timing, and Friendship Group CharacteristicsJOURNAL OF RESEARCH ON ADOLESCENCE, Issue 3 2004Shannon E. Cavanagh Scholars who have studied the effects of early pubertal timing on girls' sexual debut contend that this association may result from the company they keep. Although this basic biosocial model of adolescent behavior has been applied to various outcomes with diverse samples of adolescent girls, less work has contextualized this microlevel developmental phenomenon within the larger macrolevel structures of race and ethnicity. Using a sample of White, African American, and Latina girls (N=1,299) drawn from the National Longitudinal Study of Adolescent Health, this study conducted within-group multivariate analyses and found important differences in the linkages that make up this biosocial model by race and ethnicity, with the linkages strongest for Whites, followed by Latina, and African American girls. These differences in association may reflect differences in the social construction of girlhood across race and ethnicity. [source] Friends' Influence on Adolescents' First Sexual IntercoursePERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH, Issue 1 2006Renee E. Sieving CONTEXT: Social-psychological theories of health behavior suggest that adolescents' sexual behaviors are influenced by the sexual attitudes and behaviors of their friends. METHODS: Data on 2,436 participants in the National Longitudinal Study of Adolescent Health (Add Health) who were sexually inexperienced at Wave 1 (1994,1995) were analyzed to examine whether friend-related variables predicted initiation of vaginal intercourse by Wave 2 (1996). Analyses also assessed whether predictive relationships varied by level of involvement with friends. Odds ratios were generated by logistic regression analysis. RESULTS: In the 9,18 months between Waves 1 and 2, 18% of participants initiated intercourse. In analyses controlling for gender, family structure and romantic relationships, the higher the proportion of a youth's friends who were sexually experienced, the greater the odds of sexual debut (odds ratio, 1.01); the odds also were elevated among youth who believed that they would gain their friends' respect by having sex (1.2). Relationships between friend variables and sexual initiation did not vary by level of involvement with friends. CONCLUSIONS: To maximize the likelihood of success, programs focused on delaying teenage sexual intercourse should address norms for sexual behavior among adolescents' close friends as well as the perceptions, skills and behaviors of individual youth. [source] Infrequency of Sexually Transmitted Disease Screening Among Sexually Experienced U.S. Female AdolescentsPERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH, Issue 6 2004Lynne C. Fiscus CONTEXT: Since 1993, the Centers for Disease Control and Prevention and professional medical organizations have recommended that all sexually experienced female adolescents receive annual screening for Chlamydia trachomatis. Whether adolescents receive this care is largely unknown. METHODS: Reports of receipt of testing or treatment for a sexually transmitted disease (STD) in the past year, as well as sites of care, were obtained from 3,987 sexually experienced females in grades 7,12 who participated in Wave 1 of the National Longitudinal Study of Adolescent Health, conducted in 1995. Logistic regression was used to determine predictors of reporting care. RESULTS: Eighteen percent of all participants reported having received STD services in the past year. Of those who reported having had a routine physical examination in the past year, 22% reported receipt of STD services. The proportion reporting STD care increased linearly with age from 9% of 12,13-year-olds to 25% of those 19 or older. In adjusted analyses, the odds of reporting testing or treatment were elevated among participants who had had a physical examination in the past year (odds ratio, 2.1), those with Medicaid or Medicare insurance (1.9), black women (1.5) and older adolescents (1.2). Adolescents most often reported having received STD care at a community health center (44%) or a private physician's office (31%). CONCLUSIONS: Continued inadequate screening may contribute to persisting high prevalence of chlamydia infection among adolescents. Future research is needed to determine whether the proportions of adolescents receiving recommended STD screening have increased over time. [source] Implications of Racial and Gender Differences In Patterns of Adolescent Risk Behavior for HIV And Other Sexually Transmitted DiseasesPERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH, Issue 6 2004Carolyn Tucker Halpern CONTEXT: Sexual and substance use behaviors covary in adolescence. Prevalence of HIV and other sexually transmitted diseases (STDs) differs according to race and gender, yet few studies have systematically investigated risk behavior patterns by subgroup, particularly with nationally representative data. METHODS: A priori considerations and K-means cluster analysis were used to group 13,998 non-Hispanic black and white participants in the National Longitudinal Study of Adolescent Health, Wave 1, according to self-reported substance use and sexual behavior. Multinomial logit analyses examined racial and gender differences by cluster. RESULTS: Among 16 clusters, the two defined by the lowest risk behaviors (sexual abstinence and little or no substance use) comprised 47% of adolescents; fewer than 1% in these groups reported ever having received an STD diagnosis. The next largest cluster,characterized by sexual activity (on average, with one lifetime partner) and infrequent substance use,contained 15% of participants but nearly one-third of adolescent with STDs. Blacks were more likely than whites to be in this group. Black males also were more likely than white males to be in three small clusters characterized by high-risk sexual behaviors (i.e., having had sex with a male or with at least 14 partners, or for drugs or money). Black females generally were the least likely to be in high-risk behavior clusters but the most likely to report STDs. CONCLUSIONS: Adolescents' risk behavior patterns vary by race and gender, and do not necessarily correlate with their STD prevalence. Further investigation of adolescents' partners and sexual networks is needed. [source] The association between pubertal status and sleep duration and quality among a nationally representative sample of U. S. AdolescentsAMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 4 2005Kristen L. Knutson Many hormones play important roles in both pubertal development and sleep regulation. Because of the possible consequences of impaired sleep, including impaired health and cognition, it is important to examine whether an association between pubertal stage and sleep exists. The aim of this analysis is to examine the association between sleep and adolescent growth and developmental stage in a large sample of adolescents ages 12,16 years from a nationally representative longitudinal study. This analysis used the public-use data set of the National Longitudinal Study of Adolescent Health, an extensive survey of health and behavior among adolescents in the United States. The study included two interviews approximately 1 year apart. Pubertal development, sleep variables, and height are self-reported. Pubertal development scores were calculated by summing responses to three questions for each sex. The sleep variables include sleep duration, frequent insomnia (once/week or more), frequently waking tired (once/week or more), and insufficient sleep. The results indicate a sex difference in the association between sleep problems and pubertal development. Among females, there was a significant increase in sleep problems with increasing pubertal development score, but not among males. The negative association between sleep duration and pubertal development score, however, was significant in both males and females. There is no association between sleep duration and height velocity (inches/year) in this sample. The results, which are based on a large sample size, warrant further examination with more objective measures into the association between sleep and growth and development among adolescents. Am. J.

Cox ABSTRACT Objectives: Parenting style may be a determinant in reducing adolescent risk behavior. Previous studies have relied on a typological parenting approach, with classification into four groups: authoritative, authoritarian, permissive, and neglectful. In this study, two distinct parenting dimensions, demandingness and responsiveness, were examined as independent predictors of adolescent condom use. Design and Sample: This study used a subsample of the National Longitudinal Study of Adolescent Health (Add Health) that included 153 adolescent,mother pairs. Measurement: Maternal demandingness and responsiveness were measured using Wave I mother interviews. Logistic regression analyses were used to predict adolescent condom use at sexual debut at Wave II and to assess moderation by gender and race. Results: (1) Maternal demandingness predicted increased likelihood of condom use in African American adolescents but decreased likelihood of condom use in White adolescents; (2) maternal responsiveness did not predict condom use; and (3) gender moderation was not present. Conclusions: To provide appropriate family counseling, public health nurses need to consider racial differences in contraceptive practices. Education regarding parental supervision practices should be considered as part of nursing interventions intended to increase condom use in African American adolescents. [source] Risky Parental Behavior and Adolescent Sexual Activity at First CoitusTHE MILBANK QUARTERLY, Issue 3 2002Esther I. Wilder In comparison with other industrialized countries, the United States has exceptionally high rates of adolescent pregnancy and abortion. In 1999, nearly half of high-school students reported having had sexual intercourse, and 6 percent said they had been pregnant or gotten someone pregnant (CDC 2000). American adolescents are especially unlikely to use birth control, and those who do practice contraception tend to rely on inefficient methods (Forrest 1990). Sexual behavior at first intercourse is of particular interest because early entry into sexual activity is associated with contraceptive nonuse and a heightened risk of pregnancy (Abma and Sonenstein 2001; Koenig and Zelnik 1982; Zabin, Kantner, and Zelnik 1979). Moreover, the timing of first intercourse may be a useful marker for risky sexual behavior and a history of sexually transmitted diseases (Greenberg, Magder, and Aral 1992). For example, age at first intercourse is inversely associated with the number of lifetime sexual partners (McGuire et al. 1992). Data from the National Longitudinal Study of Adolescent Health (Add Health) were used to examine the impact of parents' behavior on adolescents' sexual experience and contraceptive use. All else being equal, adolescents whose parents engage in risky behaviors are especially likely to be sexually active and to have had sex before age 15. These findings are only partly attributable to the link between parents' risky behaviors (smoking, drinking, driving without seatbelts) and adolescents' risky behaviors (smoking, drinking, delinquent activity, association with substance-using peers). Although parental behaviors are effective predictors of adolescents' sexual activity, they are not effective predictors of contraceptive use or of method choice at first coitus. Overall, parents with low levels of self-efficacy seem to be especially likely to have children at risk of engaging in problem behaviors. [source] Prenatal drug use and the production of infant healthHEALTH ECONOMICS, Issue 4 2007Kelly Noonan Abstract We estimate the effect of illicit drug use during pregnancy on two measures of poor infant health: low birth weight and abnormal infant health conditions. We use data from a national longitudinal study of urban parents that includes postpartum interviews with mothers, hospital medical record data on the mothers and their newborns, and information about the neighborhood in which the mother resides. We address the potential endogeneity of prenatal drug use. Depending on how prenatal drug use is measured, we find that it increases low birth weight by 4,6 percentage points and that it increases the likelihood of an abnormal infant health condition by 7,12 percentage points.
