Popis: | Metacarpal and phalangeal lengths were measured on 1290 hand radiographs of Nigerian children, aged 3-16 years. The radiographs were obtained during a combined cross-sectional and longitudinal study of growth and development. There is a linear increase in tubular bone length with age in both sexes. The girls have higher values for all the bones up to the age of 13 years when the boys overtake them. Comparison of our data with those from North American children shows that the values amongst Nigerian children are higher than White, Black American and Mexican American children. Of particular note is the difference between Black American and Nigerian figures. It is postulated that the decreased metacarpophalangeal lengths in Black Americans compared with Nigerians may be due to 'gene dilution'. |
