RESUMO
OBJECTIVES: To analyse and compare the clinical profile and glycaemic outcome in known diabetic cases in South Indian urban and periurban populations. MATERIAL AND METHODS: Details of known type 2 diabetic cases identified in a population survey of diabetes in Chennai city, Kanchipuram town and Periurban Villages (PUV) of Panruti in Tamil Nadu were analyzed (n=524, M:F, 256:268). Glycaemic outcome, prevalence of hypertension, dyslipidaemia and obesity, and treatment details were studied and compared between the areas. RESULTS: Mean age at diagnosis was 45.3 +/- 10.1 years, prevalence of hypertension was 57.4% (32% known), 48% were obese and a larger percentage (63.3%) had abdominal obesity Dyslipidaemia was present in nearly 50%. Abnormalities were more in urban areas than in PUV. Glycaemic target (post prandial glucose < or =160 mg/dl) was met by 28.8% only; better results were seen in PUV. In PUV 46% were not taking any diabetic treatment. As expected, majority of patients in all areas were treated with oral drugs. CONCLUSIONS: This population-based data indicated that the clinical outcome in known diabetic cases was far from satisfactory even in the city, where specialized diabetes care was available.
