To study the prevalence of metabolic syndrome (MS) among newly diagnosed hypertensive patients in a tertiary care hospital in the northern hilly state of Himachal Pradesh, India, located in western Himalayas at a moderate altitude of 2200 m above mean sea level. One hundred and eighteen newly diagnosed hypertensive patients above the age of 20 years were studied in a hospital-based cross-sectional study. MS prevalence was estimated by International Diabetes Federation (IDF) criteria and modified National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) criteria. Student's t-test was used to compare the mean of the continuous variables. Chi-square test was used to compare discrete variables. The prevalence of MS in hypertensive patients was 68.6% (modified NCEP-ATP III) and 63.6% (IDF criteria). The most common phenotype of MS with the component of hypertension was the coexistence of waist circumference (90.1%), low high-density lipoprotein (HDL; 70.4%), and high triglycerides (67.9%) as per the modified NCEP-ATP III criteria, and low HDL (76.2%) and high triglycerides (66.4%) as per the IDF criteria. Fasting blood glucose (33.2% as per the modified NCEP-ATP III criteria and 32.6% as per the IDF criteria) was the least significant factor having an association with MS. The prevalence of MS among hypertensive patients was high and indicates the need for metabolic screening in all hypertensive patients at the first diagnosis.Keywords: Hypertension, India, metabolic syndrome, moderate altitude, western Himalayas
