Abstract Objective: Despite the rising number of patients with diabetes and hypertension in India, there is a dearth of nationwide, comprehensive prevalence data on these diseases. Our study aimed at collecting data on the prevalence of diabetes and hypertension and the underlying risk factors in various outpatient facilities throughout India. Methods: This cross-sectional study was planned to be conducted in 10 Indian states, one state at a time. It was targeted to enroll about 2,000 patients from 100 centers in each state. Each center enrolled the first 10 patients (≥18 years of age, not pregnant, signed consent) per day on two consecutive days. "Diabetes" and "hypertension" were defined by the 2008 American Diabetes Association and the Joint National Committee's 7(th) Report guidelines, respectively. Patient data (demographics, lifestyle factors, medical history, and laboratory diagnostic results) were collected and analyzed. Results: During 2009-2010, in total, 15,662 eligible patients (54.8% males; mean age, 48.9±13.9 years) from eight states were enrolled. Diabetes was prevalent in 5,427 (34.7%) patients, and 7,212 (46.0%) patients had hypertension. Diabetes and hypertension were coexistent in 3,227 (20.6%) patients. Among those whose disease status was not known at enrollment, 7.2% (793 of 11,028) and 22.2% (2,408 of 10,858) patients were newly diagnosed with diabetes and hypertension, respectively; additionally, 18.4% (2,031 of 11,028) were classified as having prediabetes and 60.1% (6,521 of 10,858) as having prehypertension. A positive association (P<0.05) was observed between diabetes/hypertension and age, familial history of either, a medical history of cardiovascular disorders, alcohol consumption, and diet. Conclusions: Our study demonstrates that the substantial burden of diabetes and hypertension is on the rise in India. Patient awareness and timely diagnosis and intervention hold the key to limiting this twin epidemic.
