The Prevalence Of Malignant Tumor And The Analysis Of Influencing Factors In Chrome Pollution Area

ObjectiveIn order to explore the prevalence of malignant tumor and the influencingfactors in chrome pollution area. Eventually, we will provide the strategy andmeasurement to prevent and control malignant rumor in chrome pollution area.MethodsThree natural village residents (8432people) in chrome pollution area wereinterviewed by cross-sectional study to collect the information of malignant tumoron January,2010～December,2010, and the research content by questionnaireand physical examination of two parts. Questionnaire includes demographicindicators (gender, age, marital status, educational level, income, etc.), everydaybehavior factors (smoking, drinking, eating habits, habits, physical activity, etc.)with water, and family history of malignant tumor, and so on and so forth; physicalexamination including height, weight, waist circumference and blood pressure.The malignant tumor standardized rates were calculated with the population ofchina in2009as standard population. The unconditional logistic regression modelwas used to analyze the relative factors of malignant tumor.ResultsThe standardized prevalence of malignant tumor in chrome pollution areawas2760per million people, which was higher than that in national rural areas(1800per million people) with a statistically significant difference (Z=2.08, P<0.05). It was showed that age (OR=2.578, P=0.000), eating vegetables mainlygrowing by themselves (OR=2.232, P=0.002), smoking (OR=1.936, P=0.028),drinking (OR=1.283, P=0.034), anxiety or stress (OR=1.762, P=0.023), and drink their own wells (OR=1.936, P=0.028), pouring land with their own wellwater (OR=2.282, P=0.005), bathing mainly with their own well water (OR=1.853, P=0.035), and have a family history of malignancy (OR=2.416, P=0.000), being engaged in the work associated with chromium(OR=2.578, P=0.000) may increase the risk of malignant tumor by unconditional logisticregression analysis.ConclusionsSignificantly increased the incidence of malignant tumor in chrome pollutionarea and Logistic regression analysis, and prompt way through a variety ofchromium contamination has caused serious damage to health of local residents.Country and the relevant functional departments should further improve theliving environment and health guidance to local residents.
