Diabetes, hypertension, and other cardiovascular disease risk factors among adults in an urban underprivileged community in Bangalore city, India

Abstract

ABSTRACT Diabetes and hypertension are major risk factors of cardiovascular disease, which is known to be the leading cause of global mortality in the world today. Studies have shown that the prevalence of these risk factors is on the rise, with the burden of diabetes alone increasing by 80% in the last two decades. Complications of diabetes and hypertension result in huge public health challenges for the country and catastrophic medical expenditures for families among the urban poor. Our study aims to estimate the prevalence of diabetes, hypertension, and other cardiovascular risk factors among adults in an urban underprivileged community of Bengaluru city. A cross-sectional study was conducted over a period of 6 months where 2245 individuals aged 30 or older were interviewed using a structured interviewer-administered questionnaire used to capture sociodemographic details that assessed modifiable risk factors for diabetes and hypertension. Inclusion criteria for diabetes were considered if the random blood sugar reading was ≥200 mg/dL, whereas a diagnosis of hypertension was taken into consideration if the systolic blood pressure reading was ≥140 mmHg and/or diastolic blood pressure was ≥90 mmHg. Among the 2245 participants that took part in the study, 15.5% were diabetics and 17.2% were hypertensive. There was a strong association of diabetes among consumers of alcohol, with more than one-third having a high prevalence of the disease (odds ratio (OR): 2.09, 95% confidence interval (95% CI): 1.1–3.9). More than half the population were consumers of junk food; the prevalence of diabetes in this group was 1.35 times higher than that in their counterparts (OR: 1.35, 95% CI: 1.0–1.8). A significant association of diabetes was also seen among those identified with central obesity (OR: 1.83, 95% CI: 1.4–2.5). One-third of the population who consumed alcohol were found to be diagnosed with hypertension (OR: 3.08, 95% CI: 1.6–5.9), and one-fifth of individuals who were regular consumers of junk food had a higher prevalence of hypertension (OR: 1.41, 95% CI: 1.1–1.8). A higher prevalence of hypertension was also seen among individuals with central obesity or a body mass index (BMI) of >30 (OR: 1.59, 95% CI: 1.2–2.1; OR: 1.92, 95% CI: 1.4–2.6). The findings from our study conducted in an urban underprivileged area of Bengaluru city shed light on the significant associations between diabetes and hypertension and various demographic and lifestyle factors. Specifically, male gender and lower educational status were found to have a significant association with diabetes, whereas being unmarried and having a high BMI status were strongly linked to hypertension. In addition, the study revealed that elderly individuals, alcohol consumers, junk food eaters, and those with central obesity demonstrated an increased risk for both diabetes and hypertension. By identifying these risk factors, targeted interventions can be developed to address the unique challenges faced by this vulnerable section of society. Strategies can be designed to raise awareness, encourage healthier lifestyle choices, and improve access to healthcare services to effectively prevent and manage diabetes and hypertension in this community.
