Exploring Condom Use Behaviors Among African American Adolescent Boys in the Deep South.

Risky sexual behaviors among adolescents can increase adverse outcomes including unplanned pregnancy or contraction or transmission of disease. Adolescents who engage in risky sexual activities are at increased risk for adverse health and social outcomes compared to those who do not engage. Despite declines in adolescent pregnancy and birth rates, the diagnosis of sexually transmitted infections (STIs) is steadily increasing among adolescents.

A longitudinal study of the impact of school delinquency on self-worth development among Black American adolescents.

Previous research found adolescents with low self-worth often utilize delinquency as a method of "self-enhancing" as proposed by Kaplan, which suggests the effects of delinquency can be both enhancing and damaging to adolescents' later reports of self-worth. We tested Kaplan's self-enhancing thesis to determine the extent to which different levels of self-worth in early adolescents foretell long-term levels of self-worth associated with delinquency among adolescents placed at-risk. Data from a sample of 982 primarily Black American (95%) adolescents living in high-poverty neighborhoods were analyzed using global and behavioral self-worth measures collected annually between the ages of 12-17, with school delinquency as the self-enhancing mechanism.

Family Matters: Examining Child Abuse and Neglect as Family Dysfunction for Minority Youth Living in Extreme Poverty.

Two competing models of child abuse and neglect (scapegoat vs. family dysfunction) are used to illustrate how the specification of victims ("index" victim vs. all children in household) from incidents of child abuse and neglect can be used to improve estimates of maltreatment for at-risk minority youth.

Bidirectional Relationships Between Parenting Processes and Deviance in a Sample of Inner-City African American Youth.

The current study assessed for bidirectional relationships among supportive parenting (knowledge), negative parenting (permissiveness), and deviance in a sample ( = 5,325) of poor, inner-city African American youth from the Mobile Youth Survey (MYS) over 4 years. Cross-lagged path analysis provided evidence of significant bidirectional paths among parenting processes (knowledge and permissiveness) and deviance over time. Follow-up multigroup tests provided only modest evidence of dissimilar relationships by sex and by developmental periods.

Does it really matter which drug you choose? An examination of the influence of type of drug on type of risky sexual behavior.

This study investigates whether certain types of substances are differentially related to certain risky sexual behaviors (RSBs) within the same population and determines whether combination substance use (SU) has additive, redundant or antagonistic effects on RSBs. African-American youth aged 9-19 participated in a large, community-based survey assessing substance use and sexual behaviors. Multilevel modeling was used to predict the differential influence of alcohol, marijuana, and cocaine use on condom use measured in the past 90days and at last intercourse, sex while drunk/high, and number of sexual partners.

Genes involved in stress response and alcohol use among high-risk African American youth.

Background: Genetic and environmental factors influence substance use behaviors in youth. One of the known environmental risk factors is exposure to life stressors. The aim of this project is to study the interaction between NR3C1 and CRHBP, genes thought to be involved in stress pathways, exposure to stressful life events, and adolescent alcohol use/misuse.

Dimensionality and Genetic Correlates of Problem Behavior in Low-Income African American Adolescents.

Researchers have long observed that problem behaviors tend to cluster together, particularly among adolescents. Epidemiological studies have suggested that this covariation is due, in part, to common genetic influences, and a number of plausible candidates have emerged as targets for investigation. To date, however, genetic association studies of these behaviors have focused mostly on unidimensional models of individual phenotypes within European American samples.

SOCIO-ECOLOGICAL PREDICTORS OF INTERCOURSE FREQUENCY AND NUMBER OF SEXUAL PARTNERS AMONG MALE AND FEMALE AFRICAN AMERICAN ADOLESCENTS.

The current study examined 14 waves of data derived from a large, community-based study of the sexual behavior of impoverished youth between 12 and 17 years of age residing in the Deep South. We used multilevel linear modeling to identify ecological predictors of intercourse frequency and number of sexual partners among gender-specific subsamples. Results indicated that predictors of adolescent sexual behavior differed by both type of sexual behavior and gender.

Change in Age-Specific, Psychosocial Correlates of Risky Sexual Behaviors Among Youth: Longitudinal Findings From a Deep South, High-Risk Sample.

The current study examined psychosocial predictors of change in intercourse frequency and number of sexual partners among youth within a socio-ecological framework and assessed whether these determinants vary by stage of adolescent development. Longitudinal data were derived from a large, community study of adolescent risky behavior among predominantly high-risk, African American youth. Significant predictors of intercourse frequency for early adolescents included age, gender, self-worth, and familial factors; for older youth, age, gender, self-worth, curfews, and sense of community exerted significant effects.

The effects of age, gender, hopelessness, and exposure to violence on sleep disorder symptoms and daytime sleepiness among adolescents in impoverished neighborhoods.

Although sleep problems are associated with negative outcomes among adolescents, studies have not focused on sleep disorder symptoms among adolescents living in impoverished neighborhoods and how sleep problems may be related to two factors common in those environments: hopelessness and exposure to violence. This study used data from the longitudinal Mobile Youth Survey (MYS; N = 11,838, 49% female, 93% African-American) to examine trajectories of sleep problems by age (10-18 years) among impoverished adolescents as a function of gender, feelings of hopelessness, and exposure to violence. The results indicate that sleep problems associated with traumatic stress decline with age, with four notable distinctions.

Associations of adolescent hopelessness and self-worth with pregnancy attempts and pregnancy desire.

Objectives: We examined the associations of pregnancy desire (ambivalence or happiness about a pregnancy in the next year) and recent pregnancy attempts with hopelessness and self-worth among low-income adolescents.

Methods: To evaluate independent associations among the study variables, we conducted gender-stratified multivariable logistic regression analyses with data derived from 2285 sexually experienced 9- to 18-year-old participants in the Mobile Youth Survey between 2006 and 2009.

Results: Fifty-seven percent of youths reported a desire for pregnancy and 9% reported pregnancy attempts.

Specifying the interrelationship between exposure to violence and parental monitoring for younger versus older adolescents: a five year longitudinal test.

Five waves of longitudinal data collected from 349 African American youth living in extreme poverty were used to examine the interrelationship between exposure to violence and parenting during adolescence. Semi-parametric group based modeling was used to identify trajectories of parental monitoring and exposure to violence from T1 to T5. Results from these analyses revealed: (1) a trajectory of declining parental monitoring for 48% of youth; and (2) four distinct trajectories of exposure to violence.

Sleep disturbance and risk behaviors among inner-city African-American adolescents.

Adolescents tend to experience more problems with sleep loss as a natural consequence of puberty, whereas teens from impoverished urban areas are likely to witness neighborhood violence and/or engage in risk behaviors that may affect sleep. Data from the Mobile Youth Survey, a longitudinal study of impoverished inner-city African-American adolescents (1998-2005; N = 20,716; age range = 9.75-19.

Does parenting shield youth from exposure to violence during adolescence? A 5-year longitudinal test in a high-poverty sample of minority youth.

Five waves of longitudinal data collected from 349 African American youth living in extreme poverty were used to determine if parental monitoring shielded youth from exposure to violence during adolescence. Semiparametric group- based modeling was used to identify trajectories of parental monitoring and exposure to violence from T1 to T5. Results from these analyses revealed (a) about 52% of youth had a trajectory of hypervigilant parental monitoring and (b) two out of the five distinct trajectories of exposure to violence were low and/or declining over the 5-year time period.

Pathways and Predictors of Antisocial Behaviors in African American Adolescents from Poor Neighborhoods.

Antisocial behavior among youth remains a serious personal and social problem in the United States. The purposes of this study were to (1) identify the shape and number of developmental trajectories of antisocial behavior in a sample of poor, inner-city African American youth, and (2) test predictors of group membership and the developmental course of antisocial behaviors. Using growth mixture modeling, we examined predictors of antisocial behavior pathways and the likelihood of arrest in a sample of 566 poor, urban African American adolescents (ages 11 to 16).

Development and risk behavior among African American, Caucasian, and mixed-race adolescents living in high poverty inner-city neighborhoods.

Youths growing up in low-income inner-city neighborhoods are at substantial risk for initiating substance use, violent behavior, and sexual intercourse at early ages; these risk behaviors continue at comparatively high rates through adolescence. Hopelessness has been implicated as a risk factor for these behaviors. In this paper, we consider how race influences this process.

The origins of hopelessness among inner-city African-American adolescents.

Much has been written in recent years about hopelessness among residents of impoverished inner-city neighborhoods, but little research has been conducted on the origins of hopelessness. The literature on social disorganization and the literature on child development independently suggest two possible causes of hopelessness among adolescents: disruptive events and lack of connectedness to people and institutions. We explore these two factors as predictors of hopelessness for 5895 youths living in impoverished inner-city neighborhoods in Mobile, Alabama.

An evaluation of a Medicaid managed maternity program: the impact of comprehensive care coordination on utilization and pregnancy outcomes.

The purpose of this study is to evaluate the effectiveness of the implementation of a Medicaid managed maternity care program in a public health department service population, analyzing race-specific models of WIC participation and risk of small-for-gestational age of term. There were 13,095 singleton deliveries during the period 1987-1990 to women with prenatal care in this managed maternity care program. The research design entailed comparison of the intervention group (those receiving regular prenatal care plus comprehensive care coordination in 1989-90) with an historical comparison group of women who received only regular prenatal care in the two years (1987-88).

Hopelessness and risk behaviour among adolescents living in high-poverty inner-city neighbourhoods.

Ethnographic literature on inner-city life argues that adolescents react to their uncertain futures by abandoning hope, leading them to engage in high levels of risk behaviour. However, few quantitative studies demonstrate this relationship. This study tests this relationship using a survey of 2468 inner-city adolescents, asking them questions about hopelessness, violent and aggressive behaviour, substance use, sexual behaviour, and accidental injury.

Touched by homelessness: an examination of hospitality for the down and out.

Objectives: This study investigated patterns of "doubled-up" homelessness using an indirect measure based on host households.

Methods: In random household telephone surveys conducted in Alabama between 1990 and 2000 and nationally in 1997, respondents indicated whether any individual had stayed with them during the past year because that person was homeless.

Results: The percentage of Alabama households providing shelter during the past year declined from 16.
