Prevalence of metabolic syndrome and its risk factors in Kerala, South India: Analysis of a community based cross-sectional study.

BACKGROUND: Coronary Artery Disease (CAD) is a leading cause of death and disability in Kerala, India. Metabolic syndrome (MS) is a constellation of established risk factors for CAD. We aimed to estimate the prevalence of MS and evaluate the association between MS and CAD using a community-based sample population. METHODS: A cross-sectional community based survey was conducted in urban and rural areas of Kerala in 2011. We included 5063 individuals for analysis. Age standardized prevalence of MS, associated diagnoses (hypertension, diabetes and hypercholesterolemia) and other potential risk factors were assessed for men and women in both urban and rural locations. Univariate and multivariate logistic regression models were developed to identify participant characteristics that are associated with MS. RESULTS: After standardization for age and adjustment for sex and urban-rural distribution, the prevalence of metabolic syndrome in Kerala was 24%, 29% and 33% for the NCEP ATP III, IDF and AHA/NHLBI Harmonization definitions, respectively. The mean (SD) age of the participants was 51 (14) years, and 60% were women. Women had a higher prevalence of MS than men (28% versus 20% for ATP III, p<0.001). Similarly, participants living in urban areas had higher prevalence of MS than their rural counterparts (26% versus 22%, p<0.001). Elevated body mass index, older age, and female sex were associated with MS in an adjusted multivariate model. The propensity for definite CAD was 1.7 times higher in individuals with MS defined based on ATP III criteria compared to those without MS (Adjusted OR = 1.69; 95% CI: 1.3-2.2, p<0.001). CONCLUSIONS: One of four to one of three adult individuals in Kerala have MS based on different criteria. Higher propensity for CAD in individuals with MS in Kerala calls for urgent steps to prevent and control the burden of metabolic conditions.

Availability, Sales, and Affordability of Tobacco Cessation Medicines in Kerala, India.

BACKGROUND: India is the world's second largest consumer of tobacco, but tobacco cessation remains uncommon due, at least in part, to underutilization of cessation pharmacotherapy. We evaluated the availability, sales, and affordability of nicotine replacement therapy, bupropion, and varenicline in the South Indian state of Kerala to understand potential reasons for underutilization. METHODS AND RESULTS: From November 2016 to April 2017, we collected data on availability, inventory, and pricing of cessation medication through a cross-sectional survey of 199 public, semiprivate (Karunya), and private pharmacies across 5 districts in Kerala using World Health Organization/Health Action International methodology. Revenue and sales data were obtained from the latest Pharmatrac medication database. We assessed affordability using individual- and household-level income and expenditure data collected from November 2014 to November 2016 through the Acute Coronary Syndrome Quality Improvement in Kerala randomized trial. Cessation medications were not available in public hospitals (0%, n=58) nor in public specialty centers (0%, n=10) including those designated to provide cessation services. At least 1 cessation medicine was available at 63% of private pharmacies (n=109) and 27% of Karunya (semiprivate) pharmacies (n=22). Among the 75 pharmacies that stocked cessation medications, 96% had nicotine replacement therapy, 28% had bupropion, and 1% had varenicline. No outlets had sufficient inventory for a patient to purchase a 12-week treatment regimen. There were an estimated 253 270 treatment regimens sold throughout India and 14 092 in Kerala in 2013 to 2014. Treatment regimens cost 1.9 to 13.0× the median amount spent on smoked tobacco and between 8% and 52% of nonsubsistence income. CONCLUSIONS: Tobacco cessation medications are unavailable in the Kerala public sector and have limited availability in the private and semiprivate sectors. When available, medications are unaffordable for most patients. Addition of tobacco cessation medication onto national and state essential medicines lists may help increase access.
