Arabic male adolescents have a high smoking prevalence. Introduction of “Class smoke-free” pledges have been successful amongst European adolescents but have not been evaluated using objective valid measures. We tested the impact of adding a smoke free pledge strategy to a proven peer–led asthma and smoking prevention program on breath carbon monoxide level (BCO) in male high-school students in Jordan.

Material and Methods:
We enrolled male students from four high-schools in Irbid, Jordan. Schools were randomly assigned to receive either TAJ (Triple A in Jordan, n= 218) or TAJ-Plus (with added class smoke-free pledge, n=215). We hypothesized that students receiving TAJ-Plus would have greater reduction in BCO levels than those only receiving the TAJ intervention. Asthma and smoking status were assessed by self-administered questionnaires. Smoking outcomes were collected using a BCO Monitor.

Both groups had significant reductions in BCO levels post-intervention (p<0.0001), however, decreases were greater in TAJ-Plus group (3.9±0.2 vs 4.8±0.2, p<0.0001). Intervention effects on BCO over time did not vary by smoking status (p=0.085), asthma status (p=0.602), or a combination of the two (p=0.702).

An added smoke-free pledge strategy to a proven peer-led asthma education program appears to be a promising approach to motivate adolescents to abstain from smoking in Jordan. Future research is required to determine if these results can be extended to Jordanian adolescent females.

The Deanship of Scientific Research at Jordan University of Science and Technology provided financial support for this study (Fund No.96/2012).
