Cancer risk among Los Angeles women with cosmetic breast implants.

Background: As the first generation of women who received cosmetic breast implants ages, questions remain about cancer risk. This study is an update of the Los Angeles Augmentation Mammaplasty Study and examines cancer risk among women with long-term exposure to breast implants.

Methods: The authors conducted a record linkage cohort study of patients with cosmetic breast implants by abstracting from records of the private practices of 35 board-certified plastic surgeons in Los Angeles County, California.

African American children's depressive symptoms: the prospective effects of neighborhood disorder, stressful life events, and parenting.

The prospective effects of observed neighborhood disorder, stressful life events, and parents' engagement in inductive reasoning on adolescents' depressive symptoms were examined using data collected from 777 African American families. Multilevel analyses revealed that stressful life events experienced at age 11 predicted depressive symptoms at age 13. Furthermore, a significant interaction between neighborhood disorder and parents' engagement in inductive reasoning was found, indicating that parental use of inductive reasoning was a protective factor for depressive symptoms particularly for youths living in highly disordered neighborhoods.

Early experience with racial discrimination and conduct disorder as predictors of subsequent drug use: a critical period hypothesis.

A critical period hypothesis linking early experiences with both racial discrimination and conduct disorder (CD) with subsequent drug use was examined in a panel of 889 African American adolescents (age 10.5 at time 1) and their parents. Analyses indicated that these early experiences did predict use by the adolescents at time 3 (T3)-5 years later.

Correlates of elevated depressive symptoms among rural African American adults with type 2 diabetes.

Objective: The study objective was to examine the health-related and sociocontextual correlates of elevated depressive symptoms among rural African American adults with type 2 diabetes mellitus.

Design: Cross sectional, observational study.

Setting: Rural communities in central Georgia, United States.

Supportive parenting moderates the effect of discrimination upon anger, hostile view of relationships, and violence among African American boys.

Studies have shown that exposure to discrimination increases the probability that African American adolescents will engage in delinquent behavior, especially acts of violence. The present study extended this research by examining the extent to which supportive parenting buffers a youth from these deleterious consequences of discrimination. Analyses based upon two waves of data from a sample of 332 African American adolescent males and their caretakers supported this hypothesis.

Ethnic pride and self-control related to protective and risk factors: test of the theoretical model for the strong African American families program.

Objective: To test a theoretical model of how ethnic pride and self-control are related to risk and protective factors.

Design: A community sample of 670 African American youth (mean age = 11.2 years) were interviewed in households.

Pubertal maturation and early substance use risks among African American children.

Using 2 waves of longitudinal data collected from approximately 870 African American adolescents, this study examined (a) changes in early risk factors for substance use during transition to early adolescence, including perceived prototypes of substance-using peers, willingness and intention to use substances, number of substance-using peers, and youths' own actual substance use; (b) the relationship between pubertal timing and these substance use risks; and (c) the interaction between pubertal timing and peer substance use in predicting the risks. Results showed that, first, risks for substance use increased, particularly among girls, during the transition to early adolescence. Children's prototypic images of substance users became increasingly favorable during this transitional period; a greater number of them were willing and intended to use substances during the transition to early adolescence; and an increased number of early adolescents and their friends began to use substances.

Perceived discrimination and the adjustment of African American youths: a five-year longitudinal analysis with contextual moderation effects.

Longitudinal links between perceived racial discrimination and later conduct problems and depressive symptoms were examined among 714 African American adolescents who were 10-12 years old at recruitment. Data were gathered 3 times over a 5-year period. Hypotheses were tested via latent curve modeling and multiple-group latent growth modeling.

The influence of high school dropout on substance use among African American youth.

The role of high school dropout in the onset and rapid escalation of substance use was investigated with 1,762 African American youth participating in the 1990 and 1992 follow-ups of the National Educational Longitudinal Study of 1988 (NELS:88). In 1990, all youth were students; most were in the 10th grade and approximately 16 years old. Path analysis models were used to examine dropout's unique contribution to substance use and its mediational effect on the association of prior problem behavior with later substance use.

A theory-based dual-focus alcohol intervention for preadolescents: the Strong African American Families Program.

This study examined mediators of the Strong African American Families Program, a randomized, dual-focus prevention trial intended to delay the onset of alcohol use and reduce alcohol consumption among rural African American youths. More specifically, it demonstrated that changes in consumption 2 yrs after the intervention were mediated through 2 different paths, a social reaction path and a reasoned/intention path. The social reaction path provided evidence that relative to the control condition, the intervention decreased children's willingness to drink by making their images of drinkers less favorable.

Effects of family risk factors on dosage and efficacy of a family-centered preventive intervention for rural African Americans.

This study was designed to test hypotheses about family risk factors and their links to dosage and efficacy of a family-centered preventive intervention. Participants were 172 families with an 11 year-old child randomly assigned to the intervention condition in the Strong African American Families Program (SAAF). Two family risk factors, ratio of adults to children in the household and youth unconventionality, were negatively related to dosage, defined as number of intervention sessions attended.

The Strong African American Families Program: a cluster-randomized prevention trial of long-term effects and a mediational model.

The Strong African American Families Program, a universal preventive intervention to deter alcohol use among rural African American adolescents, was evaluated in a cluster-randomized prevention trial. This 7-week family skills training program is based on a contextual model in which intervention effects on youth protective factors lead to changes in alcohol use. African American 11-year-olds and their primary caregivers from 9 rural communities (N = 332 families) were randomly selected for study participation.

The strong African American families program: prevention of youths' high-risk behavior and a test of a model of change.

In this study, the efficacy of the Strong African American Families Program (SAAF) was tested. The trial, which included 332 families, indicated that families who participated in SAAF experienced increases over time in regulated, communicative parenting; increases in targeted parenting behaviors, according to youths' reports; and low rates of high-risk behavior initiation among youths. Changes in regulated, communicative parenting mediated the intervention's impact on youths' recognition of changes in parenting, which in turn was linked to changes in youths' high-risk behavior.

Metro status and African-American adolescents' risk for substance use.

The relative prevalence of substance use among African-American high school students living in rural, urban, and suburban areas was examined. Students in rural areas reported equivalent or higher rates of substance use than did students in urban or suburban areas. Attention to substance use prevention among rural African-American students is warranted.

Families and risk: prospective analyses of familial and social influences on adolescent substance use.

Parental, peer, and older siblings' contributions to adolescents' substance use were investigated with 2 waves of panel data from 225 African American families. Structural equation modeling showed that older siblings' behavioral willingness (BW) to use substances at Time 1 (T1) predicted target adolescents' Time 2 (T2) use, controlling for other T1 variables. Regression analyses revealed an interaction between targets' and siblings' BW, such that targets were more likely to use at T2 if both they and their siblings reported BW at T1.

Risk and protective factors for substance use among African American high school dropouts.

Risk and protective factors that predict substance use were investigated with 318 African American high school dropout youths who completed the 1992 follow-up of the National Educational Longitudinal Study of 1988. A conceptual model linking positive family relationships and religious involvement to youths' substance use and conventional peer affiliations through a positive life orientation was examined with structural equation modeling. Positive life orientation, which included optimism and conventional goals for the future, fully mediated the influence of family relationships on conventional peer affiliations.

The impact of parenting on risk cognitions and risk behavior: a study of mediation and moderation in a panel of African American adolescents.

Hypotheses concerning the extent to which adolescents' cognitions mediate the relation between parenting behaviors and adolescent substance use were examined in a panel of African American adolescents (N = 714, M age at Time 1 = 10.51 years) and their primary caregivers. A nested-model approach indicated that effective parenting (i.

Longitudinal pathways to psychological adjustment among Black youth living in single-parent households.

A 5-wave model linking family and maternal functioning to youth psychological adjustment was tested with 139 single-mother-headed African American families with young adolescents (mean age = 11 years at recruitment) living in the rural South. Structural equation modeling indicated that an accumulation of family risk factors at Wave 1 was linked with maternal psychological functioning at Wave 2, which forecast competence-promoting parenting practices at Wave 3. These parenting practices indirectly forecast youth externalizing and internalizing behaviors 2 years later at Wave 5, through youth self-regulation at Wave 4.

Longitudinal links among parenting, self-presentations to peers, and the development of externalizing and internalizing symptoms in African American siblings.

A longitudinal model that linked involved-supportive parenting and siblings' ability-camouflaging self-presentations to peers with the development of externalizing and internalizing symptoms was tested with 152 pairs of first- and second-born African American siblings (mean ages 12.7 years and 10.2 years at the first wave of data collection).

Partnering with community stakeholders: engaging rural African American families in basic research and The Strong African American Families Preventive Intervention Program.

The Center for Family Research has implemented the first family-community preventive intervention program designed specifically for rural African American families and youths. Basic information garnered during a decade of research in rural African American communities formed the theoretical and empirical foundations for the program, which focuses on delaying the onset of sexual activity and discouraging substance use among youths. The Center's researchers have formulated future directions for engaging rural families in basic research and preventive intervention programs.

Context and cognitions: environmental risk, social influence, and adolescent substance use.

This study examined the cognitions thought to mediate the impact of context on adolescent substance use and also the extent to which context moderates the relations between these cognitions and use. Risk cognitions and behaviors were assessed in a panel of 746 African American adolescents (M age 10.5 at Wave 1, 12.

The Strong African American Families Program: translating research into prevention programming.

A randomized prevention trial contrasted families who took part in the Strong African American Families Program (SAAF), a preventive intervention for rural African American mothers and their 11-year-olds, with control families. SAAF is based on a contextual model positing that regulated, communicative parenting causes changes in factors protecting youths from early alcohol use and sexual activity. Parenting variables included involvement-vigilance, racial socialization, communication about sex, and clear expectations for alcohol use.
