PATTERN OF BIOCHEMICAL PARAMETERS IN OBESE AND NON-OBESE TYPE II DIABETIC PATIENTS ATTENDING MEDICINE OUTDOOR OF A TEACHING HOSPITAL IN KOLKATA: AN OBSERVATIONAL STUDY
Introduction: The diagnostic parameters of diabetes in obese and non obese individuals might not be always same because the physiological basis of developing diabetes in them is not similar. Objectives: The present study has been done to assess any significant difference in the Clinical and Biochemical parameters of diabetes like Glycosylated Haemoglobin (HbA1C), Fasting and Post prandial Blood Sugar (FBS and PPBS) among obese and non obese Type II Diabetes patients. Methodology: The present study was undertaken in the Medicine Outdoor of Calcutta National Medical College during June to August 2018 among 100 Type II Diabetes Mellitus patients of both sexes and aged 18 or above prior to an informed consent. Any significant difference in the Clinical and Biochemical parameters of diabetes among different groups of Diabetic patients as per BMI and waist circumference was assessed. Data was analyzed by standard statistical software like SPSS version 20 with proportion and percentage and using parametric and non-parametric tests like Chi-squares and ANNOVA. Result: The study reveals that 30% of the study population has BMI 25-29.99 kg/m2, 9% has 30-34.99 kg/m2 and 3% have BMI between 35-39.99 kg/m2 and 83.67% of Males and 96.07% of females have increased Waist Circumference Complications like Diabetic Nephropathy, Retinopathy, Neuropathy and Foot ulcer etc was found in 61% of the study population. There is significant difference in mean values of Glycosylated Haemoglobin, fasting blood sugar and post prandial blood sugar in the different groups of BMI. 32.78% of patients with complications of Diabetes Mellitus have BMI>24.99 and this association is statistically significant. Conclusion: The present study has found significant difference of the mean values of diagnostic parameters of diabetes in different groups according to Body Mass Index. However the study was performed with the population who were already on treatment for some duration, so there can be a variation of findings in the present study from other studies done in different settings like primary care hospitals or with patients at onset of diabetes.
