Publication A comparative study of body mass index (BMI) in diabetic and non- diabetic individuals in Nepalese population(Kathmandu University, 2006) Shah, A; Parthasarathi, D; Sarkar, D; Saha, CGIntroduction and Objectives: Diabetes Mellitus (DM) is the most common endocrine disorder world-wide. The prevalence of diabetes mellitus is increasing. In the present study an attempt has been made (i) to examine the relation between obesity and diabetes mellitus in Nepalese people, (ii) to find out whether BMI cut-off points for determining over weight and obesity as per WHO criteria are applicable in Nepalese study population. Materials and methods: The present study was carried out in Manipal College of Medical Sciences (MCOMS) and Manipal Teaching Hospital (MTH), Pokhara. The Diabetic patients of Pokhara and surroundings who attended the 'Diabetic Clinic' and Out Patient Department (OPD) during August 2004 to November 2004 at Manipal Teaching Hospital were included in the present study. The number of diabetic patients was two hundred (200), out of which, one hundred and fourteen (114) were male and eighty six (86) were female. In addition one hundred (100) non- diabetic subjects who attended the OPD at MTH were taken for comparison with the diabetic patients, of which, forty seven (47) were male and fifty three (53) were female. Age, height and weight were recorded for every subject. BMI was calculated by the standard formula. In the present study, body mass index (BMI) of the diabetic subjects was found to be more than that of non-diabetic subjects. BMI of non-diabetic males and females were found to be around 22 kg/m2 which is within normal range as per WHO recommendations. On the other hand, diabetic subjects’ BMI were found to be around 25 kg/m2, which denotes borderline obesity. It is clear from the present study that 51.5% of the diabetic subjects were within the normal range (BMI 18.5-24.9 kg/m2 ). More diabetic subjects were found in over-weight (25-29.9) category than non-diabetic subjects. As per WHO criteria 56% of the non-diabetic subjects were within the normal BMI range (BMI 18.5-24.9 kg/m2). It is also evident that when BMI in the range of 25.0-29.9 kg/m2 is considered as over-weight, only 33% were found to be over-weight in diabetic subjects. But when BMI ≥23 kg/m2 (as recommended for Asians) is taken as the determining factor for overweight, 64% of overweight male subjects and 72.09% of overweight female subjects were found to be diabetic. Conclusion: According to the observations of the present study on Nepalese it can be concluded that BMI cut-off points for determining over-weight and obesity should be lowered to 23 kg/m2 or less which can provide an adequate basis of taking action on risks related to overweight and obesity in Nepal.

It can easily be prevented, if timely proper measures are taken. In Kathmandu valley and Mechi Zone of Nepal, the distribution of refractive errors was found to be very high. No records are available from the Western part of Nepal. Considering the importance of the refractive errors the present study had been undertaken in Pokhara city. Materials and methods: Nine hundred and sixty four subjects (474 boys, 490 girls) were selected between age groups 10 to 19 years from six schools representing different region of Pokhara. After Preliminary examination: on acuity of vision with Snellen’s and Jaeger’s charts, the subjects were referred to the Manipal Teaching Hospital, Pokhara for confirmation of the refractive errors. Results: Sixty two schools children (6.43%), out of 964 had refractive errors. Myopia was found to be most common (4.05%). The refractive errors were found more in Private school children (9.29%) than Government school children (4.23%), which is statistically signi cant (P < 0.05). More boys (7.59%) were found to have suffered from refractive errors than girls (5.31%). Further, children with vegetarian diet (10.52%) had greater number of refractive errors than non-vegetarian diet children (6.17%). Conclusion: In the present study, percentage distribution of myopia was found to be higher (4.05%) than the hyperopia (1.24%) and astigmatism (1.14%). Interestingly, in the present study the refractive errors were found significantly higher in Private schools children than Government schools because the children who read in Private schools have higher socioeconomic status; spend more time in home work, watching Television and Computer as compared to government schools children. These near activities of the eyes causes stress on eyes of the children and might be one of the causes of developing myopia. Key words: Refractive errors, Nepal, Myopia, Hyperopia
