Most previous studies of predictors for participation in prostate-specific antigen (PSA) screening for prostate cancer have been conducted in purposive samples or clinical settings. This population-based study identified factors associated with documented PSA screening among health fair participants.
Cross-sectional survey of 2098 Nebraskan men aged 35 years and older who participated in a health fair in central and eastern Nebraska in 1993.
All participants were offered a PSA screening and a questionnaire to collect information on demographics, family medical history, lifestyle factors and self-perceived health status. Predictors of PSA screening were estimated by odds ratios (ORs) and 95% confidence intervals (CIs).
Men were more likely to accept the PSA screening if they were older than 50 years of age (OR=3.1; 2.4-3.9), had a higher income (OR=1.5; 1.1-2.1), were currently employed (OR=1.4; 1.0-2.5), perceived their health status as good (OR=1.1; 0.8-1.5) or excellent (OR=1.4; 1.0-2.1), and believed that they themselves, rather than physicians, should be responsible for their health (OR=1.3; 1.0-1.7). Compared with men aged 50-59 years, the ORs of participation were 0.8 (0.6-1.1) for age 60-69 years and 0.7 (0.5-1.1) for age 70+ years. Decision making was not related to education, marital status or body mass index. Predictors of screening remained unchanged when analysis was limited to men aged 50 years and over, whereas only high income and non-smoking status predicted participation among men younger than 50 years of age.
Age, income, employment status, perceived control of health and perceived heath status were related to participation in PSA screening for prostate cancer, particularly in men older than 50 years of age. Willingness to receive a PSA screening among men aged 50 years and over decreased with increasing age.
以往大多数关于前列腺癌前列腺特异性抗原（PSA）筛查参与度预测因素的研究都是在有目的的样本或临床环境中进行的。这项基于人群的研究确定了健康博览会参与者中与有记录的PSA筛查相关的因素。
对1993年参加内布拉斯加州中东部健康博览会的2098名35岁及以上的内布拉斯加州男性进行横断面调查。
为所有参与者提供PSA筛查和一份问卷，以收集有关人口统计学、家族病史、生活方式因素和自我感知健康状况的信息。通过比值比（OR）和95%置信区间（CI）估计PSA筛查的预测因素。
年龄超过50岁的男性（OR=3.1；2.4-3.9）、收入较高的男性（OR=1.5；1.1-2.1）、目前有工作的男性（OR=1.4；1.0-2.5）、自我感知健康状况良好（OR=1.1；0.8-1.5）或极佳（OR=1.4；1.0-2.1），以及认为应由自己而非医生对自身健康负责的男性（OR=1.3；1.0-1.7）更有可能接受PSA筛查。与50-59岁的男性相比，60-69岁男性参与筛查的OR为0.8（0.6-1.1），70岁及以上男性为0.7（0.5-1.1）。决策与教育程度、婚姻状况或体重指数无关。当分析仅限于50岁及以上的男性时，筛查的预测因素保持不变，而在50岁以下的男性中，只有高收入和非吸烟状态可预测参与情况。
年龄、收入、就业状况、对健康的感知控制和感知健康状况与前列腺癌PSA筛查的参与度有关，尤其是在50岁以上的男性中。50岁及以上男性接受PSA筛查的意愿随年龄增长而降低。
