Nicotine dependence among rural-to-urban migrant workers in Shanghai / 中华全科医师杂志

ABSTRACT

Objective To explore the nicotine dependence levels and the influencing factors of dependence among rural-to-urban migrant workers in Shanghai so as to provide scientific rationales for an effective implementation of tobacco control.Methods Multi-stage randomized sampling was used to select a total of 5 856 rural-to-urban migrant workers from 7 districts in Shanghai.Fagerstrom Test for Nicotine Dependence ( FTND) and logistic regression model were used to analyze the association between nicotine dependence and relevant risk factors.Results The current smoking prevalence was 23.7%.The average FTND score for current smokers , high dependence and low dependence were 3.38 ±2.49, 7.00 ±1.07 and 2.23 ±1.71 respectively.The high and low dependence rates were 21.7% and 78.3%.The results of logistic regression showed that education , duration of smoking and length of migration were associated with nicotine dependence.Lower level of education was more prone to high nicotine dependence.Those with a lower education had a higher risk of nicotine dependence ( junior high school OR=1.742, primary school or lower OR =1.994 vs.senior high school or higher ).High nicotine dependence increased with the duration of smoking (smoking 6-10 yearsOR=3.007, 11-15 yearsOR=4.076, 16-20 yearsOR=5.451, 20 years or moreOR=5.726 vs.5 years or less).Length of migration over 3 years was less likely to have a high nicotine dependence (3-5 years OR=0.602, more than 5 years OR=0.407 vs.<1 year) .Conclusion The rate of high nicotine dependence is high among rural-to-urban migrant workers in Shanghai.Level of education , duration of smoking and length of migration are significant influencing factors of nicotine dependence.
