The effect of faith-based smoking cessation intervention during Ramadan among Malay smokers.

To study the effects of a faith-based smoking cessation intervention during Ramadan among Malay male smokers working in public offices. This was a quasi-experimental study conducted during Ramadan 2015. The intervention was developed based on the constructs within the Theory of Planned Behaviour. The intervention intended to increase the intention and the perceived behaviour control to stop smoking among Muslim smokers during Ramadan. The outcomes measured were changes in the Fagerstrom Test for Nicotine Dependence score and saliva cotinine levels. Data were collected at baseline (5 days before Ramadan), during Ramadan (21st day of Ramadan) and post-Ramadan (21 days after Ramadan). Statistical tests to examine changes within and between groups were carried out and the significance level was set at  < 0.05. During Ramadan, the saliva cotinine level decreased significantly in both groups ( = 0.001 in the control group and  = < 0.001 in the intervention group). However, after Ramadan, it remained significant only in the intervention group ( = 0.025). A significant change between the groups was only noticed during Ramadan ( = 0.049). The reduction in the saliva cotinine level was found to be more sustainable post-Ramadan in the intervention group. This finding could indicate the positive effect of using this culturally-competent intervention to encourage smoking cessation during Ramadan.
