Abstract
OBJECTIVE: To study the relationship between socioeconomic status (SES) and esophageal squamous cell carcinoma (ESCC) in Taixing city,Jiangsu province. METHODS: A population-based case-control study was carried out to collect data including demography, socioeconomic status indicators and possible risk factors. Unconditional logistic regression was used to compare different SES indicators and composite wealth scores constructed between cases and controls, using the principal component analysis methodology. RESULTS: Factors as:having received high school or higher education (OR = 0.66, 95% CI:0.46-0.96), living space over 67 m2 per-capita (OR = 0.71, 95% CI: 0.54-0.94), drinking tap water longer than 5 years (OR = 0.76, 95% CI:0.59-0.98) and wealth score >0.93 (OR = 0.63, 95%CI:0.48-0.83)were associated with increased risk of ESCC. Compared to those worked in farming, forestry, animal husbandry, fishery and water conservancy, the individuals who worked in business-service industry were at lower risk of ESCC(OR = 0.65, 95%CI:0.43-0.97). CONCLUSION: An inverse association of low SES and ESCC were found in Taixing people that called for further explanation.
