Study on the coverage of cervical and breast cancer screening among women aged 35-69 years and related impact of socioeconomic factors in China, 2013 / 中华流行病学杂志

ABSTRACT

Objective To estimate the cervical and breast cancer screening coverage and related factors among women aged 35-69 years who were in the National Cervical and Breast Screening Program,to provide evidence for improving cervical and breast cancer control and prevention strategy.Methods Data used in this study were abstracted from the 2013 Chinese Chronic Diseases and Risk Factors Surveillance Program.A total of 66 130 women aged 35-64 years and 72 511 women aged 35-69 years were included for this study.Weighted prevalence,(with 95％ confidence interval,CI) was calculated for complex sampling design.Rao-Scottx2 method was used to compare the screening coverage among subgroups.A random intercept equation which involved the logit-link function,was fitted under the following five levelsprovincial,county,township,village and individual.Fix effects of all explanatory variables were converted into OR with 95％CI.Results In 2013,26.7％ (95％CI24.6％-28.9％) of the 35-64 year-old women reported that they ever had been screened for cervical cancer and 22.5％ (95％ CI20.4％-24.6％) of the 35-69 year-olds had ever undergone breast cancer screening.Lower coverage was observed among women residing in rural and central or western China than those in urban or eastern China (P＜0.000 1).The coverage among women aged 50 years or older was substantially lower than those aged 35-49 years.Those who were with low education level,unemployed,low household income and not covered by insurance,appeared fewer number on this cervical or breast cancer screening program (P＜0.000 1).Women living in rural and western China were having less chance of receiving the breast cancer screening (P＜0.05),but the difference was not statistically significant.Conclusion It is essential to strengthen the communitybased cervical and breast cancer screening programs,in order to increase the coverage.More attention should be paid to women aged 50 years or older,especially those socioeconomically disadvantaged ones.
