Profiles of Psychosocial Risk and Protective Factors and their Associations with Alcohol Use and Regular Smoking in Black Adults.

INTRODUCTION: This study aimed to identify the clustering of substance use-related psychosocial risk and protective factors (subgroups) and the differential associations of those subgroups with current alcohol use and regular smoking among Black adults.
METHODS: Data were drawn from 4462 participants (29% Afro Caribbean, 71% African American; median age = 38; 63% female) in a nationally representative study of social, economic, and structural conditions and health in Black Americans. Latent classes, i.e., subgroups, were derived via latent profile analysis with 10 indicators representing social support and religious involvement (support); demands from family and religious community (demands); and socioeconomic and neighborhood factors and racial discrimination (adversity). Frequency of alcohol use and prevalence of regular smoking were compared across classes using regression analyses.
RESULTS: Four classes emerged: (1) high support, low demands and adversity; (2) high support and demands, low-moderate adversity; (3) low support and demands, low-moderate adversity; and (4) low support, high demands and adversity. Relative to Class 1, frequency of alcohol use and regular smoking prevalence were significantly higher only in Class 4.
CONCLUSIONS: Results indicate substantive variations in the clustering of substance use-related psychosocial risk and protective factors in Black adults. Furthermore, they suggest that neither the presence of high demands nor the absence of support alone differentiates likelihood of engaging in frequent alcohol use or regular smoking, but adverse experiences such as racial discrimination may be especially impactful.
