Familism and inflammatory processes in African American, Latino, and White youth.

ABSTRACT: OBJECTIVE:African Americans and Latinos make up the two largest minority groups in the United States, and compared with Whites, these ethnic minority groups face disproportionate risk for certain physical health problems. However, factors that may protect these groups against early risk for poor health are not entirely understood. Familism, which emphasizes family interdependence and commitment, and is more prevalent among Latino and African American families, may be one such factor. The current study examined whether values and behaviors related to familism were differentially associated with inflammatory processes among White, African American, and Latino youth. METHOD:Participants were 257 youth who completed measures of familism values and behaviors and whose parents reported on their ethnicity. Participants also provided blood samples for the assessment of proinflammatory cytokine responses to bacterial challenge and of sensitivity to anti-inflammatory features of cortisol and interleukin (IL)-10. RESULTS:Significant familism values and behaviors by ethnicity interactions were observed. For Latino and African American youth but not for White youth, more familism values were associated with greater sensitivity to IL-10. Additionally, for African American youth, more familism behaviors were associated with decreased cytokine responses to bacterial challenge and greater sensitivity to cortisol and IL-10. By contrast, familism behaviors were associated with lower sensitivity to cortisol in White youth and were not associated with any inflammatory outcomes in Latino youth. CONCLUSION:This pattern of findings suggests that for African American youth and to some extent for Latino youth, familism values and behaviors may be protective against the elevated risk for poor health they face.

Project description:BackgroundAfrican Americans (AA) have more favorable bone density and microarchitecture compared to Whites (W), which may explain their observed lower fracture rates. Obesity has deleterious effects on bone microarchitecture and strength estimates and is associated with an increase in fracture risk. Adolescence and young adulthood are periods of active bone accrual and also periods characterized by an increasing prevalence of obesity. The effect of obesity on the relationship between race and bone parameters remains unclear, particularly in youth.ObjectiveTo assess differences in BMD, bone microarchitecture and strength estimates in AA and W adolescents and young adults with moderate to severe obesity. We hypothesized that racial differences in bone endpoints in lean youth would also be noted in youth with moderate to severe obesity.MethodsWe evaluated 24 AA and 48 W adolescent and young adults with a mean age of 18.2 ± 2.4 years and a median body mass index (BMI) of 44.8 (40.5-49.4) kg/m2 who underwent dual energy X-ray absorptiometry (DXA), high resolution peripheral quantitative computed tomography (HRpQCT), extended cortical analysis (ECA) and micro-finite element analysis (FEA) to obtain measures of volumetric bone mineral density (vBMD), bone geometry, microarchitecture, and strength estimates at the distal radius and tibia.ResultsWe found no differences between AA and W for total fat and lean mass, and areal BMD Z-scores (p > 0.05 for all). At the distal radius, no significant differences were detected in vBMD, bone geometry or microarchitecture (p > 0.05 for all); however, stiffness and failure load were higher in the AA group (p = 0.031 and 0.047 respectively). At the distal tibia, cortical vBMD was higher in AA vs. W (p = 0.012), while trabecular number was higher and trabecular separation lower in W vs. AA (p ≤ 0.028). Stiffness and failure load trended higher in AA vs. W (p = 0.052 and p = 0.048, respectively). Groups did not differ for any other bone parameter (p > 0.05).ConclusionRacial differences in bone endpoints appear to be less marked in those with moderate to severe obesity, suggesting that effects of obesity may blunt the effect of race on bone endpoints.
