To compare the effectiveness of interviewer-led and postal surveys in gathering adequate health data for occupational health programmes among farmers.
Two cross-sectional studies of farmers from southern New Zealand were conducted. Farms were randomly selected from the public land valuation roll and all farmers and farm workers invited to participate in the farmers' health study. First, 477 farms were invited to participate in an interviewer administered questionnaire and health check; and second, a further 432 farms were selected and invited to participate in a self-administered postal survey. Both groups completed the same questionnaire.
The response for the interviewer-led and postal surveys was 65.4 % and 51.6 % respectively. The 2 groups differed demographically, with fewer young farm workers in the postal survey, but were similar in all areas of health information collected, except that men in the interviewer-led survey were significantly more likely to have a psychological disturbance than men in the postal survey (chi ( 2 ) =5.06, df=1, p=0.024).
Despite the interviewer-led survey having a higher response rate, the postal survey produced similar health data, which is adequate for planning occupational health programmes for farmers. Extra effort should be made to recruit younger farm workers in future research.
比较访谈式调查和邮寄式调查在为农民职业健康项目收集充分健康数据方面的有效性。
对来自新西兰南部的农民进行了两项横断面研究。从公共土地评估名册中随机选取农场，邀请所有农民和农场工人参与农民健康研究。首先，邀请477个农场参与由访谈员管理的问卷调查和健康检查；其次，另外选取432个农场并邀请其参与自行填写的邮寄式调查。两组都完成相同的问卷。
访谈式调查和邮寄式调查的回应率分别为65.4%和51.6%。两组在人口统计学特征上存在差异，邮寄式调查中的年轻农场工人较少，但在收集的所有健康信息领域都相似，只是访谈式调查中的男性比邮寄式调查中的男性患心理障碍的可能性显著更高（卡方检验(2)=5.06，自由度=1，p=0.024）。
尽管访谈式调查的回应率较高，但邮寄式调查产生了相似的健康数据，这足以用于规划农民的职业健康项目。在未来的研究中应额外努力招募年轻的农场工人。
