Screening may be effective for reducing deaths due to prostate cancer. The aim of this study was determine the prevalence and determinants influencing prostate cancer early detection behaviors based on the theory planned behavior (TPB). In this cross-sectional study, conducted in the west of Iran, a total of 250 men aged 50 to 70 years old were randomly selected to participate. Of these, 200 (80%) signed the consent form and voluntarily agreed to take part. A structured questionnaire based on TPB constructs was applied for collecting data by interview. Analyses were conducted with SPSS version 16 using bivariate correlations, and logistic and linear regression. Some 26.5% of the participants demonstrated prostate cancer early detection behavior. Age higher than 60 (OR: 5.969), academic education (OR: 2.904), number of family members more than four (OR: 3.144), and knowledge about prostate cancer (OR: 3.693) were the most influential predictive factors for early detection behavior. Furthermore, among the TPB constructs, attitude (OR=1.090) and subjective norms (OR=1.280) were the most influential predictors. Attitude, subjective norms, and perceived behavioral control accounted for 43% of the variation in the outcome measure of the intention to screen for prostate cancer (adjusted R squared= 0.43, F= 49.270 and P < 0.001). Designing and implementation programs to increase positive attitudes and encourage subjective norms towards prostate cancer screening behavior may be useful for promotion of early detection.
筛查可能对降低前列腺癌死亡有效。本研究的目的是基于计划行为理论（TPB）确定影响前列腺癌早期检测行为的患病率和决定因素。在伊朗西部进行的这项横断面研究中，随机选取了250名年龄在50至70岁之间的男性参与。其中，200人（80%）签署了同意书并自愿同意参与。通过访谈应用基于TPB结构的结构化问卷收集数据。使用SPSS 16版进行双变量相关性分析以及逻辑回归和线性回归分析。约26.5%的参与者表现出前列腺癌早期检测行为。年龄大于60岁（OR：5.969）、接受过学术教育（OR：2.904）、家庭成员数超过四人（OR：3.144）以及对前列腺癌的了解（OR：3.693）是早期检测行为最具影响力的预测因素。此外，在TPB结构中，态度（OR = 1.090）和主观规范（OR = 1.280）是最具影响力的预测因素。态度、主观规范和感知行为控制占前列腺癌筛查意愿结果测量变异的43%（调整后R平方 = 0.43，F = 49.270，P < 0.001）。设计和实施旨在增强对前列腺癌筛查行为的积极态度并鼓励主观规范的项目可能有助于促进早期检测。
