Observations among Swedish farmers indicate that coxarthrosis is a common disorder in farming populations. In this case-referent study, we describe relationships between farming and hip joint arthrosis. The case-group consisted of 105 persons who have had surgery because of coxarthrosis and the referents consisted of 222 randomly selected persons. Non-responders totaled 9%. Farming was significantly more common in the case group. The ratio varied between 2.1 and 3.2, varying with the length of time in farming. Longer exposure did not seem to result in greater risk. There was no risk elevation related to forestry or transportation work. Nor was there any over-representation of accidents with injuries to the lower extremities in the case group. Heavy work load did not seem to be related to the genesis of coxarthrosis. Farming is an amalgamation of different types of work. However, we develop the hypothesis from this study that tractor driving may be related to hip arthrosis. Unfavorable angles in the hip joints may occur during tractor driving. Other studies support this hypothesis, as it has been found that unsuitable conditions for the hip joints may be related to arthrosis.
瑞典农民中的观察结果表明，髋关节病是农业人口中的一种常见病症。在这项病例对照研究中，我们描述了务农与髋关节病之间的关系。病例组由105名因髋关节病接受手术的人组成，对照组由222名随机挑选的人组成。无应答者总计9%。务农在病例组中明显更为常见。该比例在2.1至3.2之间变化，随务农时间长短而不同。较长时间的接触似乎并未导致更高的风险。与林业或运输工作无关的风险升高情况也不存在。病例组中也没有下肢受伤事故的过度代表情况。繁重的工作量似乎与髋关节病的发生无关。务农是不同类型工作的混合。然而，我们从这项研究中提出假设，即驾驶拖拉机可能与髋关节病有关。驾驶拖拉机时髋关节可能会出现不利角度。其他研究支持这一假设，因为已经发现髋关节的不合适条件可能与关节病有关。
