Abstract: Background and Objective: Osteoporosis is a growing health dilemma recognized in both developed and developing countries associated with substantial morbidity worldwide. The present study aimed to determine the prevalence of osteoporosis in type 2 diabetes mellitus patients using Dual energy X-ray absorptiometry (DEXA) scan. Materials and Methods: Data were collected from type 2 diabetes mellitus patients attending orthopaedics and diabetes centre who were willing to undergo DEXA Scan. The DEXA was done at hip and spine to assess bone mineral density (BMD). Various other risk factors were evaluated through a questionnaire. T-Scores and Z-Scores have been measured for the presence of osteoporosis based on WHO criteria. Descriptive statistics, t-test and Mean±SD was used as statistical test. Data were entered and analyzed using SPSS. Results: A total of 96 type 2 diabetes mellitus patients were studied. The study revealed the prevalence of osteoporosis at the spine 39.6% while at the hip 20.9%. The overall incidence seen was 43.8%. Predominantly, osteoporotic diabetes had lower body weight and lower body mass index with reduced duration of exposure to sunlight. The prevalence of osteoporosis was higher among the group with a positive history of alcohol and smoking. Conclusion: The present study indicates that high prevalence of osteoporosis in type 2 diabetes mellitus patients is a cause for concern. Measures such as adequate vitamin D and calcium intake, physical activity and exposure to sunlight will be useful in preventing the occurrence of osteoporosis.
