OBJECTIVE The study aimed at association of family life, resilience and bullying on the use of tobacco in preadolescents. METHODS A total of 4792 students from 5 junior schools in Baise City were recruited with cluster-sampling method, filled with questionnaire of family life, resilience, parents' Control, bullying, initiation of tobacco and smoking from Feb. to Nov. 2018.The sample comprised of 52.63% male students and 46.66% female students. The average age was(11.8±0.5). There were 56.78% of students lived in city and 43.22% of students lived in county town; The nationality of the sample was as follows: Zhuang nationality 90.00%, Han nationality 7.62%, other minorities(Yao nationality, Miao nationality, Yi nationality, et al)2.05%. The Logistic regression was used to explore the effect. RESULTS There were 9.75% and 6.97% of the sample reported initiation of tobacco and smoking respectively. The initiation of tobacco and smoking of boys were higher than that of girls(initiation of tobacco: χ~2=57.230, P<0.001; smoking: χ~2=56.013, P<0.001). The multivariate Logistic analysis showed gender was statistically significant factor of initiation of tobacco(OR=0.468, 95%CI 0.377-0.582) and smoking(OR=0.422, 95% CI 0.324-0.551), and age was statistically significant factor of initiation of tobacco(OR=1.609, 95% CI 1.446-1.791) and smoking(OR=2.026, 95%CI 1.776-2.310). Bullying was statistically significant factors of smoking(OR=1.106, 95% CI 1.073-1.140). Three protective factors were associated with a lower likelihood of initiation of tobacco(individual power: OR=0.964, 95% CI 0.951-0.976; family cohesion, OR=0.946, 95% CI 0.892-0.984; family rules, OR=0.949, 95%CI 0.930-0.965) and smoking(individual power: OR=0.962, 95% CI 0.947-0.977; family cohesion, OR=0.937, 95%CI 0.885-0.992; family rules, OR=0.952, 95%CI 0.932-0.973)in the final subscale model. CONCLUSION Bullying increased the risk of smoking, while Individual power, family cohesion and family rules were associated with a lower likelihood of initiation of tobacco and smoking in preadolescents.
