Abstract
                 Background: Physical activity is a fundamental means of improving the physical and mental health of individuals, its  beneficial effect on the metabolic risk factors such as obesity, weight, lipid profile, blood glucose, and blood pressure  has been well established. There is a change in pattern of physical activity in India, which has nearly made 50%-80% of  Indians physically inactive, predisposing them to obesity and metabolic risk factors, which increases the risk of NCDs and  its consequences. Objective: To study the pattern of physical activity, estimating the prevalence of metabolic syndrome and risk factors and  to assess the effect of physical activity on metabolic syndrome and its risk factors. Materials and Methods: It was a cross-sectional study among 320 secondary school teachers of Mysore City. A self-  administered, pretested, and structured questionnaire based on the WHO Steps Approach for noncommunicable disease  risk factors and physical activity was evaluated using GPAQ questionnaire. Result: The prevalence of metabolic syndrome was 38.3% and physical inactivity was 67.7%. Those who were physically  less active had three times risk of developing MS (OR = 3.25). The proportion of physical inactivity was inversely propor- tional to the risk factors for metabolic syndrome such as body mass index, obesity, hypertension, and low high-density  lipoprotein cholesterol. Conclusion: The high levels of metabolic risk factors in the urban population, working population, and younger age group  especially the modifiable risk factors (obesity and physical inactivity), which are preventable and hence if targeted (regular,  moderate physical activity) will be a very cost-effective way of improving and maintaining the health and help in having  healthy workforce. The work places interventions can be an effective intervention.
