Discrimination, Segregation, and Chronic Inflammation: Testing the Weathering Explanation for the Poor Health of Black Americans
Peer reviewed Peer reviewed
Direct linkDirect link
Simons, Ronald L.; Lei, Man-Kit; Beach, Steven R. H.; Barr, Ashley B.; Simons, Leslie G.; Gibbons, Frederick X.; Philibert, Robert A. – Developmental Psychology, 2018
Several studies have reported a relation between race-related stressors and the poor health of Black Americans. Such findings raise questions regarding the mediating biological mechanisms that might account for this link. The present study investigated elevated systemic inflammation, a factor shown to be a strong predictor of chronic illness and…

Beach, Steven R. H.; Lei, Man-Kit; Brody, Gene H.; Kim, Sangjin; Barton, Allen W.; Dogan, Meesha V.; Philibert, Robert A. – Child Development, 2016
A sample of 398 African American youth, residing in rural counties with high poverty and unemployment, were followed from ages 11 to 19. Protective parenting was associated with better health, whereas elevated socioeconomic status (SES) risk was associated with poorer health at age 19. Genome-wide epigenetic variation assessed in young adulthood…

Gibbons, Frederick X.; Roberts, Megan E.; Gerrard, Meg; Li, Zhigang; Beach, Steven R. H.; Simons, Ronald L.; Weng, Chih-Yuan; Philibert, Robert A. – Developmental Psychology, 2012
The impact of 3 different sources of stress--environmental, familial (e.g., low parental investment), and interpersonal (i.e., racial discrimination)--on the life history strategies (LHS) and associated cognitions of African American adolescents were examined over an 11-year period (5 waves, from age 10.5 to 21.5). Analyses indicated that each one…

Prevention Effects Moderate the Association of 5-HTTLPR and Youth Risk Behavior Initiation: Gene x Environment Hypotheses Tested via a Randomized Prevention Design
Peer reviewed Peer reviewed
Direct linkDirect link
Brody, Gene H.; Beach, Steven R. H.; Philibert, Robert A.; Chen, Yi-Fu; Murry, Velma McBride – Child Development, 2009
A randomized prevention design was used to investigate a moderation effect in the association between a polymorphism in the "SCL6A4"("5HTT") gene at 5-HTTLPR and increases in youths' risk behavior initiation. Participation in the Strong African American Families (SAAF) program was hypothesized to attenuate the link between 5-HTTLPR status and risk…

Brody, Gene H.; Yu, Tianyi; Chen, Yi-Fu; Kogan, Steven M.; Evans, Gary W.; Beach, Steven R. H.; Windle, Michael; Simons, Ronald L.; Gerrard, Meg; Gibbons, Frederick X.; Philibert, Robert A. – Developmental Psychology, 2013
The health disparities literature has identified a common pattern among middle-aged African Americans that includes high rates of chronic disease along with low rates of psychiatric disorders despite exposure to high levels of cumulative socioeconomic status (SES) risk. The current study was designed to test hypotheses about the developmental…

Parenting Moderates a Genetic Vulnerability Factor in Longitudinal Increases in Youths' Substance Use
Peer reviewed Peer reviewed

Brody, Gene H.; Beach, Steven R. H.; Philibert, Robert A.; Chen, Yi-fu; Lei, Man-Kit; Murry, Velma McBride; Brown, Anita C. – Journal of Consulting and Clinical Psychology, 2009
The authors used a longitudinal, prospective design to investigate a moderation effect in the association between a genetic vulnerability factor, a variable nucleotide repeat polymorphism in the promoter region of "5HTT" (5-HTTLPR), and increases in youths' substance use. The primary study hypothesis predicted that involved-supportive…
