The prevalence of type 2 diabetes mellitus and impaired fasting glucose in semi-urban population of Nepal.

The increase in life expectancy in developing countries and as a result of increasing obesity and other life style changes, the global incidence of type 2 diabetes mellitus (T2DM) is increasing. The purpose of this study was to investigate the prevalence of T2DM and impaired fasting glucose (IFG) in semi-urban population of Nepal and to compare the prevalence between men and women and among different age groups. A total 740 adults (286 men and 454 women) aged 21 to 94 years (men +/- SD; 45.6 +/- 15.6 years) were included. The prevalence of T2DM and IFG was 9.5% and 19.2% in the whole population. Prevalence of T2DM was higher in men (11.8%) then in women (7.9%), similarly IFG was noted higher in men (25%) then in women (15.4%0). The prevalence of T2DM and IFG was seen to be increased with age in the whole population. Among women, the prevalence of T2DM and IFG was 2.9% and 12.8% in 21 to 40 years age group, 9.7% and 13.8% in 41 to 60 years age group and 15.4% and 27.7% in > 60 years age group. Among men, it was 4.7% and 22.6% in 21 to 40 years age group, 13.3% and 30.5% in 41 to 60 years age group and 23% and 17.3% in > 60 years age group. To conclude, the overall prevalence of T2DM and IFG increases with age. Prevalence of IFG is highest among middle age men where as the prevalence of T2DM is highest among older men.

Study on cyclospora cayetanensis associated with diarrheal disease in Nepal and Loa PDR.

A study of diarrheal diseases associated with Cyclospora cayetanensis was conducted in Nepal and Lao PDR. A total of 2083 samples were included in this study. Samples in Nepal were collected from October 1999 to August 2002 whereas samples in Lao PDR were collected from February 2002 to June 2003. C. cayetanensis was detected by direct microscopy using ultraviolet and differential interference contrast microscopy. The overall positive rate in Nepal was 9.2% (128/ 1397). A higher positive rate was observed in children aged 10 years and under (11.1%) and was lowest in the age group of 51-60 years (3.1%). A significantly higher positive rate was observed in the summer (rainy season) (12.6%) with the lowest prevalence in the spring (dry season) (1.8%) (p < 0.05). The positive rate was closely associated with rainfall (ml/month). Interestingly, only one of the total 686 samples (0.1%) from Lao PDR was found to be positive for Cyclospora oocysts.

Study on enteric parasitosis and nutritional status of school children in remote hilly areas in Nepal.

We examined the effect of enteric parasitosis on nutritional status of school children in remote hilly areas in Nepal. A total of 325 school children aged 6 to 19 years (boys: 214; girls: 111) who provided both blood and stool samples were included. The height (Ht) (cm), weight (Wt) (kg), age, sex, ethnic of each child were recorded. Fecal samples were examined by direct smear method in duplicate. The blood hemoglobin (Hb) was estimated by Sahli's method in the field (Nepal) whereas the serum protein (Prot), albumin (Alb), Alb/globulin ratio (A/G), serum glutamate pyruvate transaminase (SGPT), cholesterol (Chol), triglycerides (Trig), and serum iron (SI) were measured in Japan. Of the total, 201 (61.8%) had enteric parasites, predominantly the soil transmitted helminths. Ascaris lumbricoides was the most common parasite detected (72.6%) followed by hookworm (16.2%) and others. Protozoan infections were very low (<6.0%). Of the total 201 parasite positive children, 15.4% had multiple infections. No significant differences in Ht and Wt in parasite positive and negative boys and girls of both age groups (< 11 and 11-19 years) were observed (P>0.05). Overall, no significant differences in levels of Hb, Prot, A/G, SGPT, Chol, Trig and SI in the parasite positive and negative children were observed (P>0. 05) but in Alb level (P<0.05). When, the levels of these parameters were compared in the age groups of <11 and 11-19 years, similar findings were observed in both the age groups. But, in the age group of 11-19 years, a significant difference was observed in Trig level (P<0.05). No differences were found in the levels of these parameters in the parasitic positive and negative children belonging to Dalits and different ethnic namely, Indo-Aryan and Tibeto-Burman, respectively.
