ObjectiveTo understand the status quo of relapse behavior among drug addicts and its related factors.

MethodsA total of 1 225 community residents were randomly selected by stratified proportional sampling method. Data were collected by face-to-face questionnaire survey. Descriptive analysis， one-factor chi-square test and binary logistic regression were used to analyze the drug relapse behavior and possible related factors.

ResultsA total of 1 219 valid questionnaires were collected， with a recovery rate of 99.5%. The majority of the respondents were male （86.2%）， rural household registration （78.3%）， education level in junior high school or above （55.0%）， and unmarried （54.1%）， with an average age of （37.18±10.71） years old. 36.8% of the respondents had relapse behavior. The possible risk factors of relapse were age （OR=4.225， P<0.001）， education level （OR=1.530， P=0.003），urban and rural residence （OR=1.778， P=0.001）， employment status （OR=1.559， P=0.007）， marriage status （OR=1.581， P=0.001）and family support （OR=1.756， P=0.006） .

ConclusionWe should focus on the influence of demographic factors such as age， education level， employment status， marital status， family relationship and social support under the background of urban-rural differences on relapse behavior of drug addicts. The whole society should work together to create a good environment for rehabilitation， effectively prevent the relapse behavior of drug addicts， and actively help them return to society smoothly， so as to reduce the social burden.
