Global positioning system: A new tool to measure the distribution of anemia and nutritional status of children (5-10 years) in a rural area in south India.

Global positioning system (GPS) is a satellite-based navigation system that is of late being used in health care. Objectives: The aims of the study were to describe the geographical distribution and assess the prevalence of anemia and malnutrition in children aged 5-10 years with GPS. Subjects and Methods: This exploratory study was conducted over a period of 2 months in the rural field practice area of a medical college situated in Bangalore during June-July 2012. Children aged 5-10 years were the study subjects. Results: GPS was used for describing the geographical distribution of anemia and nutrition status on the Google earth map. The prevalence of anemia in the study subjects was 8.7%. The prevalence of underweight, stunting, thinness, and severe thinness among the study subjects was 52.8%, 28.5%, 23.5%, and 29.1%, respectively; however, overweight and obesity were observed only in 0.9% and 1.2% of the study subjects, respectively. Conclusion: GPS was easy to use and was able to demonstrate the actual distribution of morbidity at the household level in the rural area.
