Results: The prevalence was 41.7% for hypertension, 25% for Diabetes mellitus, 6.9% for dyslipidaemia. Education level was significantly related to hypertension, X2 = 11.565 (1), p =0.001; obesity was significantly related to diabetes, X 2 = 8.333 (1), p=0.004. After adjusted for covariates, low education level has 13.379 odds of getting hypertension.
