Among women, breast cancer is the most common non-cutaneous cancer and second most common cause of cancer-related death. The purpose of this study was to determine the extent to which women use mobile mammography vans for breast cancer screening and what factors are associated with repeat visits to these vans.
A case-control study. Cases are women who had a repeat visit to the mammography van. (n=2134).
Women who received a mammogram as part of Siteman Cancer Center's Breast Health Outreach Program responded to surveys and provided access to their clinical records (N=8450). Only visits from 2006 to 2014 to the mammography van were included.
The main outcome is having a repeat visit to the mammography van. Among the participants, 25.3% (N=2134) had multiple visits to the mobile mammography van. Data were analysed using χ(2) tests, logistic regression and negative binomial regression.
Women who were aged 50-65, uninsured, or African-American had higher odds of a repeat visit to the mobile mammography van compared with women who were aged 40-50, insured, or Caucasian (OR=1.135, 95% CI 1.013 to 1.271; OR=1.302, 95% CI 1.146 to 1.479; OR=1.281, 95% CI 1.125 to 1.457), respectively. However, the odds of having a repeat visit to the van were lower among women who reported a rural ZIP code or were unemployed compared with women who provided a suburban ZIP code or were employed (OR=0.503, 95% CI 0.411 to 0.616; OR=.868, 95% CI 0.774 to 0.972), respectively.
This study has identified key characteristics of women who are either more or less likely to use mobile mammography vans as their primary source of medical care for breast cancer screening and have repeat visits.
在女性中，乳腺癌是最常见的非皮肤癌，也是癌症相关死亡的第二大常见原因。本研究的目的是确定女性使用流动乳腺钼靶检查车进行乳腺癌筛查的程度，以及哪些因素与再次前往这些检查车就诊有关。
一项病例对照研究。病例为再次前往乳腺钼靶检查车就诊的女性（n = 2134）。
作为西特曼癌症中心乳腺健康外展项目一部分接受乳腺钼靶检查的女性参与了调查并提供了临床记录（N = 8450）。仅纳入2006年至2014年期间前往乳腺钼靶检查车的就诊情况。
主要观察指标是再次前往乳腺钼靶检查车就诊。在参与者中，25.3%（N = 2134）多次前往流动乳腺钼靶检查车。使用χ²检验、逻辑回归和负二项回归分析数据。
与年龄在40 - 50岁、有保险或为白种人的女性相比，年龄在50 - 65岁、无保险或为非裔美国人的女性再次前往流动乳腺钼靶检查车就诊的几率更高（比值比分别为1.135，95%置信区间1.013至1.271；1.302，95%置信区间1.146至1.479；1.281，95%置信区间1.125至1.457）。然而，与提供郊区邮政编码或有工作的女性相比，报告农村邮政编码或失业的女性再次前往检查车就诊的几率较低（比值比分别为0.503，95%置信区间0.411至0.616；0.868，95%置信区间0.774至0.972）。
本研究确定了更有可能或不太可能将流动乳腺钼靶检查车作为乳腺癌筛查主要医疗保健来源并再次就诊的女性的关键特征。
