Abstract

Background: Subtypes of obesity exist that appear to deviate from the standard relationship between increased body mass index (BMI) and its metabolic consequences, including metabolic syndrome. Physical activity is an important effect modifier in the relationships between obesity and metabolic status. Aims &
Objective: To evaluate metabolic syndrome variables in normal weight and overweight morning walkers.
Materials and Methods: The present cross-sectional study was conducted to evaluate metabolic syndrome variables in normal weight (Group I) and overweight/obese (Group II) morning walkers. Blood pressure and anthropometric measurements were recorded and after an overnight fast, blood samples taken were assessed for glucose and lipid profile. The joint interim statement criteria were applied for diagnosis of metabolic syndrome.
Results: In Group I, there were 43.5% of individuals who were metabolically obese in spite of their normal weight (MONW); while in Group II, there were 19% overweight/obese individuals without obesity related metabolic abnormalities (MHO). Conclusion: Waist circumference and triglycerides were the strongest markers for metabolic syndrome in both the normal weight and overweight groups; 91.6% cases of metabolic syndrome among morning walkers were associated with elevated waist circumference values. Metabolic syndrome variables in both groups were similar. Majority of subjects had normal HDL-cholesterol, suggesting favorable effect of physical activity on HDL-cholesterol
