Background: Metabolic syndrome includes abdominal obesity measured by waist circumference, increased blood pressure, fasting glucose, triglycerides and reduced high density lipoprotein–cholesterol (HDL–C). Higher prevalence of metabolic syndrome in middle aged women has been reported.  The prevalence of the metabolic syndrome differs greatly in different populations. So the present study was planned to determine  the prevalence of metabolic syndrome in pune urban middle aged women Methods: Depending on menstrual history total 300  pre, peri and postmenopausal women were included (100 in each group) in the study.  Clinical identification of the metabolic syndrome was done as per the joint interim statement. ANOVA (Analysis of Variance) and chi square test were used for comparison between three groups. Results : Mean levels & percentage of  WC, blood pressure, FBG and TGs were higher in peri & highest in postmenopausal women as compared to premenopausal women.   HDL cholesterol levels were lower than normal and  similar  in all three groups.  In the present  study 29%,65%,69% was the prevalence of metabolic syndrome  in pre ,peri and postmenopausal group respectively. Conclusion : Mets prevalence was maximum in postmenopausal women. WC ,Blood pressure and triglycerides were the predominant components of Mets. Postmenopausal women were less physically active therefore lifestyle modifications such as increase in physical activity and reduced caloric intake is likely to alter the prevalence of Mets.
