A total of 182 villages/communities were regarded as clusters, and allocated to screening arm or control arm randomly. Face-to-face interview through a questionnaire interview, including of relevant risk factors of gastric cancer, was administered for each subject. Participants were further classified into high-risk or low-risk groups based on their exposure to risk factors. All participants were followed up until December 31, 2019. Cumulative incidence rates from gastric cancer between high-risk and low-risk groups were calculated and compared using the log-rank test. Cox proportional hazard regression models were applied to estimate hazard ratio(HR) and 95% confidence interval(95% CI).Results: Totally, 89,914 residents were recruited with a mean follow-up of 3.47 years. And 42,015(46.73%)individuals were classified into high-risk group and 47,899(53.27%) subjects were categorized into low-risk group.Gastric cancer was diagnosed in 131 participants, of which 91 were in high-risk group. Compared with the low-risk participants, high-risk individuals were more likely to develop gastric cancer(adjusted HR=2.15, 95% CI,1.23-3.76). The sensitivity of the questionnaire-based model was estimated at 61.82%(95% CI, 47.71-74.28) in a general population.Conclusions: Our questionnaire-based model is effective at identifying high-risk individuals for gastric cancer. 关键词：Gastric cancer risk assessment risk factors China
