This case-referent study investigated the relation between hip osteoarthritis and occupational activity. The subjects were 60- to 75-year-old men who had undergone intravenous urography. Interviews were obtained for 245 cases who had a hip replacement for osteoarthritis or a joint space of ≤ 2.5 mm and 294 referents whose joint space was ≥ 3.5 mm in both hips. No clear associations were found in an analysis of all the cases, but severe disease (hip replacement for osteoarthritis or a joint space of ≤ 1.5 mm) was more common in the farmers, especially in those with ≥ 10 years in agricultural work [odds ratio (OR) 2.0, 95% confidence interval (95% CI) 0.9-4.4]. Severe disease was also associated with prolonged standing at work (OR 2.7, 95% CI 1.0-7.3) and heavy lifting (OR 2.5, 95% CI 1.1-5.7). These associations could not be explained by obesity or sporting activity. The findings suggest an increased risk of degenerative hip disease for farmers and indicate that mechanical overloading may contribute to its pathogenesis.
