A field study about the nutritional status was made in school classes with boys 6 to 19 years old in different regions of Saudi-Arabia. It is reported about 341 pupils in regard to weight, height, skinfold-thickness, circumferences and other body-size measurements. In comparison with anthropometric measurements of comparable surveys in other countries, the Saudi-Arabian school boys were found to be smaller and leaner than boys from the USA, Europe, other Arabian countries and well-to-do Indian boys.
