title: Bone age determination in a paediatric population as an indicator of nutritional status.
abstract: The United Mission to Nepal Tansen Project is in the hill country, 300 km West of Kathmandu. This 40-year-old service centre's major emphasis has been on clinical and community medicine and education. Agronomy, forestry, water resources development, adult literacy, etc., have also been part of the project's outreach. We had long noted that the children of all of the various tribal groups in the area are small for their age as compared with children in developed countries. Fracture care X-rays were examined to reveal delay in ossification and in physeal closure. Using the standards found in the Radiographic Atlas of Skeletal Development of the Hand and Wrist, we quantified this apparent delay by determining the bone age of all patients presenting at the hospital with upper limb injuries requiring X-ray. The collection of data was limited to 100 days and to those under the age of 21. Two hundred and nineteen patients' data were analysed. We found that bone maturation delay was very common and often severe. The average bone age among the 219 was 28% below chronological age. That is, 60% of all fell two standard deviations below the norm: i.e. two-thirds of all 9 year olds had the expected skeletal development of 6 year olds in Boston, USA. Dental age was also analysed using deciduous tooth shedding and tooth eruption patterns. Dental age retardation averaged 21%, but a larger per cent had normal eruption dates. Other physical and sociological data were included in a questionnaire completed for each patient. Among the variables examined, poverty alone appeared to be the major mover. We believe that national small stature is a result of lifelong community dietary inadequacy.
