Abstract
Studies of the distribution of rheumatic diseases in various populations are useful in determining the pattern and the prevalence of the disease and the effect of factors such as climate, diet, Cultural Patterns and race on the occurrence of these diseases, such Studies may prove useful in identifying risk Factors for Certain rhematic diseases hoping for Modifying these Factors for Certain rheumztic diseases. Ceteoarthritis (O.A.) has a world wide distribution. But Polyariticular diseases is uncommon in many Paris of the third world (Bremner et al., 1988 and Brightan 1989). Heberden’s nodes are Similarly uncommon in Africans and Jamaicans (Bremner et al., 1968 and Muller, 1970), O.A. of the hip Joint is Uncommon in Contrast with O.A. of the xnee among Chinese, Africans, Indians and in Middle East. Various Socio-Cultral Activities. Including Squatting and Keeling either in Prayer or as a from of greating, have suggested to influence this distribution of joint O.A. also, development knee abnormalities from rickets, trauma or parasitic infection and alow prevalence of congental hip abnormalities in certain areas may determine O.A. joint distribution. The habit of Carrying loads on the head by some populations does not seem to predispose to cervical spondylosis (adebajo, 1990).
