New Haven survey of joint diseases. XVII. Relationship between some systemic characteristics and osteoarthrosis in a general population.

In a survey of the general population the presence or absence of osteoarthrosis of the hand was determined radiologically in 685 adults (300 males and 385 females). Of these, 261 (124 males and 137 females), chosen randomly, were given a complete clinical examination of the musculoskeletal system which included x-ray of joints elsewhere in the body. Osteoarthrosis (OA) scores for the hand and for all body sites were computed for each subject by summing the number of affected joints. For all subjects soical class, height, weight, total serum protein, serum uric acid, haemoglobin, antistreptolysin O, (ASO), C-reactive protein (CRP), and rheumatoid factor were also measured. Analyses were carried out by simple comparison of means and by calculating multiple regressions and correlations.
