Does adherence to antihypertensive pharmacotherapy improve adequate control of hypertension in hypertensive urban slum dwellers in Kolkata, India?
Among urban slum dwellers in Kolkata, self-reported adherence to antihypertensive therapy is 73% and is strongly driven by access to free drugs, treatment satisfaction, and longer disease duration, which translates to better blood pressure control.

May support adherence emphasis among Kolkata slum dwellers; hypothesis-generating, prospective trials needed to confirm causality.
A cross-sectional study was conducted to determine the prevalence and predictors of adherence to modern antihypertensive pharmacotherapy among slum dwellers in Kolkata, India. Prevalence of adherence based on patient self-reports of consuming ≥80% of the prescribed medications over a recall period of 1 week was found to be 73% (95% confidence interval = 68%-78%). Compared with their counterparts, the following patients were more likely to be adherent to treatment: patients hypertensive for ≥5 years (2.98 times), those whose hypertension was detected during checkups for conditions related to hypertension (2.35 times), those living with ≤4 family members (2.01 times), those with family income of ≥3000 rupees (2.56 times), those who were getting free drugs (4.16 times), patients perceiving current blood pressure to be under control (2.23 times), and those satisfied with current treatment (3.77). Those adherent to their prescribed medications were 1.71 times more likely to achieve adequate control of hypertension compared with those who were not adherent.

Bhandari et al. (2011) conducted a cross-sectional in Hypertension. Adherence to antihypertensive pharmacotherapy vs. Non-adherence was evaluated on Prevalence of adherence (consuming ≥80% of prescribed medications over 1 week) (95% CI 68-78). Among hypertensive slum dwellers in Kolkata, adherence to antihypertensive therapy was 73% (95% CI 68-78%) and was associated with a 1.71-fold higher likelihood of adequate blood pressure control.
