Effectiveness of tobacco-control intervention program among high risk population of chronic non-communicable diseases in institutions from Chongqing / 中华疾病控制杂志

ABSTRACT

Objective To explore the effect of the classified management intervention model on the smoking status of high risk population of chronic non-communicable diseases in institutions from Chongqing, so as to provide scientific basis for the management of high risk population of chronic non-communicable diseases. Methods Workers from governments and institutions of four districts in Chongqing were sampled by cluster sampling. High risk population of non-communicable disease were screened and enrolled into the intervention group and control group. The intervention group were intervened by classified management. And the control group weren’t intervened. To evaluate the change of smoking and smoking hazard cognition in intervention group and control group after one year intervention. Results The result of analysis of the net effect of intervention measures using difference in difference regression model showed that the intervention measures could reduce the smoking rate, the current smoking rate and the daily smoking rate in subjects (OR=0.32, 95% CI 0.21-0.49; OR=0.31, 95% CI 0.20-0.48; OR=0.34, 95% CI 0.21-0.54). The intervention measures could increase the awareness rates of smoking causing serious diseases, stroke and lung cancer in subjects (OR=2.19, 95% CI 1.08-4.42; OR=1.73, 95% CI 1.17-2.57; OR=2.17, 95% CI 1.25-3.77), the difference was statistically significant (all P<0.05). Conclusion The intervention model of classified management for high risk population of chronic non-communicable diseases in institutions can effectively improve the awareness rate of smoking hazards among the subjects, and then reduce the smoking rate. Therefore, this intervention model is worth popularizing and applying.
