An approach to diabetes prevention and management: the Bhutan experience.

Bhutan has been witnessing a trend of increasing diabetes in recent years. The increase is attributed to a rise in risk factors such as overweight, high blood pressure, unhealthy diet and sedentary lifestyle among the population. To address the rising burden, the health-services response has been to establish diabetes clinics in all hospitals and grade one basic health units. People visiting the health centres who have high risk factors and symptoms for diabetes are screened using the World Health Organization cut-off level for blood glucose. They are then classified into prediabetes and diabetes. Accordingly, diet, medicine and physical activity are recommended as per their body mass index. To improve prevention and control of noncommunicable diseases, which include diabetes, the country piloted the WHO Package of Essential Noncommunicable (PEN) disease interventions for primary health care in low-resource settings in 2009, to promote early screening, treatment and follow-up, and adopted it in 2013. The WHO PEN has now been successfully integrated into the primary health-care system nationwide. It is planned that diabetes clinics will be upgraded to NCD clinics.

Status of Thiamin deficiency in boarding school children from seven districts in Bhutan with previous history of peripheral neuropathy outbreaks: a cohort study.

Introduction: Peripheral neuropathy outbreaks have been a common occurrence amongst boarding schoolchildren from seven districts in Bhutan. Thiamin deficiency has always been suspected to be the cause but the status of the vitamin has never been established. This study aims to find the status of thiamin and dietary intake of micronutrients in boarding schoolchildren from seven districts with previous history of peripheral neuropathy outbreaks. Methods: Whole blood thiamin and dietary intake of micronutrients were assessed in 448 school children for four study periods (SP). Baseline data (SP1) was collected when the school children just joined the school at the start of the school academic year. SP2 was the first half of the school year and the data was collected just before the midterm break. SP3 was the short summer break and SP4 the second half of the school academic year. Results: 50.58% of the school children were found to be thiamin deficient at baseline which increased to 90.1% in SP2. The percentage of thiamin deficient school children increased to 91.8% in SP3 and then decreased to 79.82% in SP4. The requirements for vitamin B1, B12, vitamin A and iron were never met by dietary intakes in all the study periods. Conclusions: In conclusion, this study found a high prevalence of Thiamin deficiency in schoolchildren at baseline and the number of school children with Thiamin deficiency increased when in schools. The school children also had inadequate dietary intake of many micronutrients.
