Predictors of participation in breast cancer screening in recent years or the trend of participation rate by predictors over the years has not been investigated in Japan. In this study, we investigated predictors for participation in breast cancer screening and analyzed the trend of participation rate depending on the predictors using nationally representative survey data in Japan.
The data of "Comprehensive Survey of Living Conditions" in Japan from 2001 to 2013 were used. Participation in breast cancer screening was used as an outcome. Next, as explanatory variables, we used age group, marital status, living arrangements, educational level, household income, employment status, smoking status, regular outpatient visit status, and self-rated health status. Then, the participation rate for breast cancer screening was calculated for each of the factors over the years. In addition, multivariate logistic regression analysis was conducted to analyze the association between each factor and the participation rate using data from 2010 and 2013.
We found that non-married women, women with lower educational level, women with low household income, self-employed or unemployed women, smokers, and women with low self-rated health status were significantly less likely to participate in breast cancer screening. Conversely, the participation rate increased for all predictor groups from 2001 to 2013, and the increase in the participation rate for never-married women was particularly evident compared with the other marital statuses. However, significant differences in the participation rate for breast cancer screening existed depending on marital status, household income, employment status, and smoking status throughout the analyzed years.
Our findings suggest that further recommendations for breast cancer screening are particularly needed among women of low socioeconomic status and those who are self-employed or unemployed to increase the participation rate in Japan.
在日本，近年来参与乳腺癌筛查的预测因素或预测因素的参与率趋势尚未得到调查。在这项研究中，我们调查了参与乳腺癌筛查的预测因素，并使用日本全国代表性调查数据分析了根据预测因素的参与率趋势。
使用日本“综合生活状况调查”2001 年至 2013 年的数据。将参与乳腺癌筛查作为结果。接下来，作为解释变量，我们使用年龄组、婚姻状况、居住安排、教育水平、家庭收入、就业状况、吸烟状况、定期门诊就诊状况和自我评估健康状况。然后，计算了每年每个因素的乳腺癌筛查参与率。此外，使用 2010 年和 2013 年的数据进行多变量逻辑回归分析，以分析每个因素与参与率之间的关联。
我们发现，未婚女性、教育程度较低的女性、家庭收入较低的女性、自营职业或失业女性、吸烟者和自我评估健康状况较差的女性参与乳腺癌筛查的可能性明显较低。相反，所有预测因素组的参与率从 2001 年到 2013 年都有所增加，与其他婚姻状况相比，未婚女性的参与率增加尤为明显。然而，在整个分析期间，乳腺癌筛查的参与率取决于婚姻状况、家庭收入、就业状况和吸烟状况存在显著差异。
我们的研究结果表明，特别是在社会经济地位较低的女性和自营职业或失业的女性中，需要进一步建议进行乳腺癌筛查，以提高日本的参与率。
