Recent studies have suggested an excess of coxarthrosis (osteoarthrosis of the hip joint) among Swedish farmers. The prevalence of coxarthrosis in the city of Malmö has previously been studied by coincidental examination of the hip joints on colon roentgenograms. The present study estimates the prevalence of coxarthrosis in farmers by examining the hip joint on roentgenograms of the colon and urinary tract. Fifteen-thousand farmers and farm workers affiliated with the Swedish Farmers' Safety and Preventive Health Association and all farmers aged 40 years or older in the Swedish country of Ostergötland were questioned about previous roentgenographic examinations. Four hundred thirty-five colon examinations and 465 urograms were available and scrutinized by the same physician. Forty-five of 565 male farmers and farm workers, aged 40-64 years, were found to have roentgenographic signs of primary coxarthrosis, compared with ten of 1250 men in the corresponding age group in the urban population of Malmö. The difference represents a rate ratio of 12 with a 95% confidence interval of 6.7 to 21.4. There was no difference in the prevalence of coxarthrosis among the female farmers and women in the urban population. The result suggests a relationship between coxarthrosis and farm work in men.
近期研究表明，瑞典农民中髋关节骨关节炎（髋关节骨关节炎）的发病率过高。此前，马尔默市曾通过对结肠X光片上的髋关节进行偶然检查，对髋关节骨关节炎的患病率进行过研究。本研究通过对结肠和尿路X光片上的髋关节进行检查，估算农民中髋关节骨关节炎的患病率。对隶属于瑞典农民安全与预防健康协会的1.5万名农民和农场工人，以及瑞典东约特兰省所有40岁及以上的农民，询问他们之前的X光检查情况。有435份结肠检查和465份尿路造影可供同一位医生仔细查看。在40至64岁的565名男性农民和农场工人中，有45人被发现有原发性髋关节骨关节炎的X光迹象，而在马尔默城市人口中相应年龄组的1250名男性中，有10人有此迹象。这一差异代表的发病率比值为12，95%置信区间为6.7至21.4。女性农民和城市女性中髋关节骨关节炎的患病率没有差异。该结果表明男性髋关节骨关节炎与农业劳动之间存在关联。
