Abstract

Background

The proportion of non-regularly employed persons has increased in Japan, but few studies have examined the relationship between employment status and lung cancer screening (LCS) participation.

Methods

Authors analyzed data from the 2010 Comprehensive Survey of Living Conditions in Japan. The anonymous responses of 28,951 people aged 40–69 years old were analyzed. Authors defined nine employment status categories: unemployed, regularly employed in a large-, middle-, and small-scale company, non-regularly employed in a large-, middle-, and small-scale company, self-employed, and other. LCS participation in the past year was surveyed through a self-reported questionnaire. Sex-specific prevalence ratios (PRs) and 95% confidence intervals (CIs) for LCS participation for all employment status categories, using the regularly employed in a middle-scale company category as the reference, were calculated using multivariable Poisson regression analysis, after adjusting for potentially confounding factors.

Results

Multivariable-adjusted PRs (95% CI) for LCS participation for the regularly employed in a large-scale company were 1.33 (1.25–1.41) in men and 1.53 (1.38–1.71) in women. Multivariable-adjusted PRs (95% CI) for LCS participation for the non-regularly employed in a middle- and small-scale company compared with the regularly employed in a middle-scale company were 0.81 (0.72–0.92) and 0.62 (0.50–0.76) in men, and 0.89 (0.80–0.99) and 0.80 (0.71–0.91) in women, respectively.

Conclusion

Regularly employed in a large-scale company had significantly higher LCS participation, and non-regularly employed in a middle- or small-scale company showed significantly lower LCS participation than those who were regularly employed in a middle-scale company.

使用生活条件综合调查，根据社会经济状况，日语中的就业和公司规模与肺癌筛查参与之间的关系。

摘要

背景

在日本，非正规就业者的比例有所增加，但是很少有研究检查就业状况与肺癌筛查（LCS）参与之间的关系。

方法

作者分析了2010年日本生活状况综合调查中的数据。分析了28951名40-69岁的人的匿名回复。作者定义了九种就业状况类别：失业，定期在大，中，小型公司工作，非正规在大，中，小型公司工作，自营职业等。通过自我报告的问卷调查了过去一年中LCS的参与情况。在调整后，使用多变量Poisson回归分析，以多变量Poisson回归分析法计算了所有就业状况类别中LCS参与的按性别分列的患病率（PRs）和95％置信区间（CIs）。对于潜在的混杂因素。

结果

大型公司经常雇用的参加LCS的多变量调整后PR（95％CI）为男性1.33（1.25-1.41），女性1.53（1.38-1.71）。与中型公司的非正规雇员相比，非中型公司的非正规雇员对LCS参与的多变量调整后PR（95％CI）为0.81（0.72-0.92）和0.62（0.50-男性分别为0.76（0.86（0.80-0.99）和0.80（0.71-0.91）。

结论

定期在大型公司工作的LCS参与率显着较高，而在非中小型公司工作的非正规人员的LCS参与率则明显低于在常规公司中雇用的LCS。
