Effects of asthma on nicotine dependence development and smoking cessation attempts in adolescence.
OBJECTIVE
The aim of this study was to investigate whether asthma predicts the development of nicotine dependence and unsuccessful smoking cessation attempts in adolescent smokers. In addition, whether nicotine dependence could explain the relation between asthma and unsuccessful cessation attempts was also investigated.


METHODS
A longitudinal survey study was conducted among 286 adolescents (aged 12-15 at T1) who had never used tobacco at baseline and were current smokers at follow-up 22 months later. Regression analyses were applied to test the effects of four asthma indicators (current wheeze, indication of asthma, symptom severity, and current diagnosed asthma) on nicotine dependence and smoking cessation attempts.


RESULTS
Both adolescents who had an indication of asthma as well as adolescents with higher symptom severity developed higher levels of nicotine dependence over time and made a greater number of unsuccessful smoking cessation attempts in the past 12 months compared to those without asthma or less severe symptoms. Nicotine dependence partly mediated the effects of asthma symptoms on unsuccessful cessation attempts. Current wheezing and current diagnosed asthma did not predict nicotine dependence or unsuccessful quit attempts.


CONCLUSIONS
Nicotine dependence develops more quickly in youth with symptoms of asthma, and this partly explains the increased number of unsuccessful cessation attempts of adolescents with asthma. Smoking prevention and smoking cessation programs are encouraged to provide additional support for youth with asthma, focusing on both the physiological and psychological aspects of dependence.
