Multivariate logistic regression analysis showed that being over 60 years of age (OR 1.67; 95% CI 1.18–2.37; p = .003), being widowed or divorced (OR 1.56; 95% CI 1.03–2.35; p = .035], smoking (OR 1.78; 95% CI 1.07–2.65; p = .01], BMI > 25 kg/m2 (OR 1.51 95% CI 1.05–2.78), having a waist circumference ≥ 90 cm (OR 1.7; 95% CI 1.2–2.42; p = .003], the use of calcium channel blockers (OR 2.69; 95% CI 1.26–5.72; p = .01], and the use of angiotensin converting enzyme inhibitors (OR 1.66; 95% CI 1.01–2.72; p = .044] contributed significantly to poor control of hypertension. This evidence concerns the gene ACE and Hypertension.
