Specific Aim #2: Multiple linear regression will be used to test the effect of mean trust/mistrust scores on health utilization and mean hemoglobin A1C, blood pressure, and LDL cholesterol after 12 months of follow-up controlling for covariates. Similarly, multiple logistic regression will be used to test the effect of trust/mistrust on acceptance of the influenza vaccine controlling for covariates. STATA V8.0 will be used for data analysis and all tests will be two-tailed with overall p=0.05 for each hypothesis.
