The Effect of Providing Genetic Risk Information on Lifestyle Behaviors in African Americans (LINKING GAINS)
Cardiovascular disease (CVD) is a major and persistent health disparity for African Americans. Linking GAINS is a randomized pilot and feasibility study designed to evaluate whether receiving genetic risk information early in a community-based CVD risk reduction intervention improves engagement and health behavior change. Sixty African American adults from the Baton Rouge metropolitan area will be recruited and randomized to a Genetically Unblinded (GU) group or a Genetically Blinded (GB) group. All participants will complete a 14-session behavioral intervention delivered over approximately 16 weeks, including culturally responsive education, nutrition and cooking sessions, physical activity training, group support, and community-based health resources. The GU group will receive genetic results and genetic counseling early in the intervention, while the GB group will receive genetic results and counseling after the behavioral intervention and end-of-study assessment. The primary endpoint is intervention engagement measured by attendance. Secondary outcomes include physical activity, dietary intake, body mass index, blood pressure, genomic orientation/knowledge, and perceived racism. Exploratory/moderator analyses will examine whether social determinants of health, including income, food insecurity, health literacy, occupational prestige, and experiences of racism, influence intervention engagement and behavior change.

有源比较器：Genetically Unblinded
Genetically unblinded participants received their genetic test results from Color Genomics: Cancer, CVD, and Pharmacogenomics panels before starting the health behavior intervention. In addition, they received a 1:1 genetic counseling session prior to the health behavior intervention completion. |
Participants gave a saliva sample to Color Genomics for an Ancestry, Hereditary Cancer, CVD, and Pharmacogenomics testing panel. Participants were able to get visuals of their results using their website and also discuss findings via zoom or phone call. |
