The term "metabolic syndrome" is given to the condition in which there is a coexistence of a constellation of interrelated factors that increase the risk for development of diabetes mellitus, nonfatal and fatal cardiovascular disease as well as all cause mortality. Patients with COPD may be at an increased risk of development of MetS due to limitation to physical activity imposed by respiratory symptoms. Methods: A cross sectional study was designed to study the prevalence of metabolic syndrome

... in 100 patients with COPD (Indian Guidelines). The characteristics of the metabolic syndrome were measured and conclusions were drawn regarding presence of metabolic syndrome as per the International Diabetic Federation Guidelines (2005). Results: Out of total number of 100 patients of COPD, 28 satisfied the criteria of metabolic syndrome. This constitutes 28%. The mean age of patients with metabolic syndrome was 61years. Male to female ratio was about 2:1. The number of smokers with metabolic syndrome was almost double that of nonsmokers. The smoking index of patients with metabolic syndrome was 212 on an average. The most common metabolic abnormality found was raised fasting blood sugar (average FBS level was 106 mg%). The mean waist circumference was 93cm, mean triglyceride level was 153mg%, mean HDL level was 44 mg%, mean systolic and diastolic blood pressure was 147 and 89 mm Hg respectively. Within the various COPD groups (Indian guidelines), all the patients with Severe COPD had metabolic syndrome, but none of the patients with Mild COPD had metabolic syndrome. Conclusions: This study revealed a high prevalence of metabolic syndrome in the north Indian population suffering from COPD particularly those having more severe grade of COPD. During the period of the study there was no fatal event in the study group. All the patients were put on appropriate treatment after enrollment in the study and were doing well till last follow up
