目得：描述非参与者在以人群为基础的研究心血管疾病和调查的影响，不参与对心肌梗死的风险估计。方法：使用随机数字拨号，我们获得了1054成人（60.8%的女性）的全部信息，而345个合格的个人（72.5%的女性）拒绝邀请参加，但回答了有限的问题，通过电话。对474例（19.4%为女性）首次急性心肌梗死患者进行心肌梗死危险度评估。结果：病例组参与率为99.0%，对照组为70.0%。非参与者人口年龄较大（男性为61.6岁，女性为58.5岁，女性为62.9岁，女性为57.7岁），女性比例更高（66.3%比74.7%，p < 0.001）;男性往往不喝酒，并且在前一年进行过血液检查;此外，女性更经常不吸烟。粗和调整后的心肌梗死的风险估计一般是相似的，无论考虑提供的信息由nonparticipants.CONCLUSIONS：在这个南欧人口，人口和社会特征与决定参加社区调查是不同的，通常描述在北方欧洲或美国人口。然而，他们的特点并不影响心肌梗死风险估计的方向或幅度。(C)2004爱思唯尔公司All rights reserved.
PURPOSE: To characterize non-participants in a population-based study on cardiovascular diseases and investigate the effect of non-participation on risk estimates for myocardial infarction.METHODS: Using random digit dialing we obtained full information for 1054 adults (60.8% female), while 345 eligible individuals (72.5% female) declined the invitation to participate, but answered a limited set of questions by telephone. Risk of myocardial infarction was estimated using 474 cases (19.4% females) admitted with a first acute myocardial infarction.RESULTS: Participation proportion was 99.0% for cases and 70.0% for population controls. Population non-participants were older (61.6 vs. 58.5 years, for males, and 62.9 vs. 57.7 years for females) and more frequently women (66.3% vs. 74.7%, p < 0.001); males tended to be non-drinkers and to have had a blood test during the previous year; females were additionally more often non-smokers. Crude and adjusted risk estimates for myocardial infarction were generally similar regardless of considering the information provided by non-participants.CONCLUSIONS: In this South European population, demographic and social characteristics associated with the decision to participate in a community investigation were different from those usually described in Northern European or American populations. However, their characteristics did not influence the direction or the magnitude of myocardial infarction risk estimates. (C) 2004 Elsevier Inc. All rights reserved.
