Abstract
Aims: This study aimed to evaluate the impact of brief smoking cessation intervention on smoking cessation outcomes as well as on glycaemic and blood pressure control among patients with diabetes.Methods: This was a randomised controlled trial involving patients with diabetes who smoked tobacco and attended the out-patient Diabetes Clinic at Penang Hospital in Malaysia. One hundred forty participants were randomised into either control (n = 70) or intervention (n = 70) groups. The intervention consisted of a 5-minute physician-delivered brief counselling on tobacco cessation using 5A’s strategy (Ask, Advise, Assess, Assist, and Arrange) in addition to usual care for patients with diabetes, while the control group received only the usual care. Results: There was no significant difference between the two groups with respect to glucose control, blood pressure levels, and smoking abstinence rates (P >0.05). Furthermore, significant main effects were found between the groups with respect to the number of cigarettes smoked per day (F [1,116] = 6.306). Conclusions: Brief smoking cessation intervention did not result in better abstinence rates or glycaemic control in patients with diabetes. However, it resulted in reduction in the number of cigarettes smoked per day over the study period (6 months), which is the first step in the tobacco cessation process. Trial registrationApproval for the conduct of this study was granted by the Medical Research Ethics Committee of the Ministry of Health, Malaysia and the Clinical Research Centre at Hospital Pulau Pinang, Malaysia (NMRR-11-477-9538) at (05-10-2011).
