The respiratory health of 230 female and 1,734 male farming students (FS) and 407 male rural controls was analyzed. A significantly increased prevalence of cough (6.9%) was reported among the male FS compared to the controls (2.5%). Measured FEV1 and FVC did not differ between the male FS and the controls, as opposed to significantly higher values among the female FS compared to a random sample of urban females stratified for height. Skin prick test (SPT) to house dust and storage mites was significantly more prevalent among the controls (18.7%) compared to the male FS (12.8%) and the female FS (11.9%). The size of the house dust mite weal and the number of positive skin prick reactions were significantly associated with bronchial hyperreactivity. The difference in lung function among the female FS and the lower prevalence of skin reaction among the male FS and female FS probably reflects a healthy workers selection.
对230名女农业专业学生、1734名男农业专业学生以及407名农村男性对照者的呼吸健康状况进行了分析。与对照组（2.5%）相比，男农业专业学生咳嗽患病率显著升高（6.9%）。男农业专业学生与对照组的第一秒用力呼气容积（FEV1）和用力肺活量（FVC）测量值无差异，而女农业专业学生的这些值与按身高分层的城市女性随机样本相比显著更高。与男农业专业学生（12.8%）和女农业专业学生（11.9%）相比，对照组对屋尘和储藏螨的皮肤点刺试验（SPT）阳性率显著更高（18.7%）。屋尘螨风团大小和皮肤点刺阳性反应数量与支气管高反应性显著相关。女农业专业学生肺功能的差异以及男农业专业学生和女农业专业学生皮肤反应患病率较低可能反映了健康工人的选择效应。
