Prevalence rate of self-reported cancer and related influencing factors among different occupational populations of China in 2015
Objective To investigate the prevalence rate of self-reported cancer and its influencing factors among different occupa-tional populations of China in 2015,as well as the primary prevention strategies for such populations.Methods This study used the data of self-reported cancer among different occupational populations in China Chronic Disease and Risk Factor Surveillance(CCDRFS)in 2015.Descriptive statistics was used to analyze the frequency and proportion of categorical var-iables,the chi-square test was used for comparison of nominal categorical variables,and an unordered polytomous logistic regression analysis was used for univariate and multivariate analyses to investigate influencing factors.Results A total of 108 665 people completed the self-reported cancer questionnaire,with 50 604 males and 58 061 females.Totally 1 809 people reported having cancer,including 689 males(1.36％)and 1 120 females(1.93％);769 people(1.92％)in the east-ern region,465 people(1.50％)in the central region,and 575 people(1.52％)in the western region.Among different oc-cupational groups,except for other practitioners(C8)who are not convenient to classify,the highest cancer incidence rate(0.56％)was among workers in agriculture,forestry,animal husbandry,fishing,and water conservancy industries(C5),while the lowest cancer incidence rate(0.01％)was among workers in state organs,party and mass organizations,enterprises,and public institutions(C1).Among different cancer types,breast cancer had the highest prevalence rate(0.33％),while liver cancer had the lowest prevalence rate(0.02％).The results of the unordered multifactorial logistic re-gression analysis of the influencing factors of different occupational cancer populations showed that eastern and central regions,and alcohol consumption were the occupational risk factors for cancer(P＜0.05).Conclusions Different occupational groups suffer from cancer in different ways,and the associated risk factors are also different.It is recommended that,while strengthening cancer prevention and control for the whole population,attention should be paid to cancer prevention for the occupational population and cancer protection for the occupational population should be strengthened;the concen-tration of risk factors in the workplace should be monitored regularly to reduce exposure to occupational risk factors;cancer publicity and education should be carried out to improve the health literacy of the occupational population;and reg-ular physical examinations should be carried out to reduce the risk of the occupational population of contracting cancer.
