Burden, determinants and treatment status of metabolic syndrome among older adults in India: a nationally representative, community-based cross-sectional survey

Abstract

IntroductionMetabolic syndrome is a significance driver of mortality and morbidity in India, but nationally representative data regarding disease burden and treatment status are lacking. Here, a cross-sectional study was undertaken to establish national and regional estimates of disease burden and explore reasons for lack of treatment of component conditions of metabolic syndrome in Indian older adults (45 years and older).MethodsA cross-sectional study was undertaken using data from the first wave of the Longitudinal Ageing Study in India (2017–2018). Data for 66 606 individuals aged 45 years and above were analysed. The primary outcome was metabolic syndrome prevalence, defined by the National Cholesterol Education Programme ATP III criteria as an individual having any three of four component conditions: diabetes mellitus (DM), hypertension, abdominal obesity and hypercholesterolaemia. The secondary outcome of this study was treatment status of patients with component conditions.ResultsMetabolic syndrome was found to have an overall weighted prevalence of 4.83% (n=3630, 95% CI 4.24 to 5.51). Females, urban residents, obese individuals and physically inactive people exhibited greater prevalence. The most prevalent component of metabolic syndrome was hypertension followed by abdominal obesity, DM and hypercholesterolaemia. 8.85% metabolic syndrome patient reported no treatment for component conditions, while 17.58% reported only partial treatment. Elderly individuals between 60 and 69 (crude relative risk ratios, cRRR 2.20, 95% CI 1.20 to 4.01) and 80 years and above (cRRR 7.48, 95% CI 1.99 to 28.16), urban residents (cRRR 2.45, 95% CI 1.48 to 4.05), those from richer monthly per capita consumption expenditure quintiles (cRRR 2.55, 95% CI 1.00 to 6.47) and those with additional comorbidities (cRRR 2.17, 95% CI 1.28 to 3.70) were more likely to report comprehensive treatment.ConclusionsThis study highlights a substantial prevalence of metabolic syndrome in older adults in India and reveals remarkable disparities in provision of treatment. Better prevention, earlier detection and improved provision of treatment are urgently required to combat the rising prevalence of metabolic syndrome and reduce the burden of cardiovascular disease in India.
