Abstract
Introduction: Evidence on smokeless tobacco (ST) cessation interventions is scarce. The South Asian (SA) region which shares more than 90% of the burden of ST use, is grossly underrepresented in research on ST cessation. This study aimed to assess the feasibility of delivering and investigating a behavioural support intervention for ST cessation in dental settings in Pakistan.
Methods: A multi-centre, pilot, 2-armed parallel group, individually randomised control trial, with a 1:1 allocation ratio, was conducted at two dental hospitals. Eligibility criteria included: being a ST user; seeking dental treatment and; not currently accessing cessation support. All participants were provided written self-help, ST cessation material. The intervention group also received a dentist-delivered, bespoke behavioural support intervention for ST cessation developed for users of SA origin. Participants were followed up telephonically at three and six months. Self-reported six month abstinence was verified by salivary cotinine. Analysis was descriptive, with 95% confidence intervals presented where appropriate.
Results: 100 participants were successfully recruited from the selected hospitals. Of these 78% continued to engage throughout the study duration and provided primary outcome data, whereas, 63% completed all hospital visits. The outcome measures were successfully collected. Biochemically verified six-month abstinence in the intervention and control group was 10% and 4%.
Conclusions: It was feasible to deliver and evaluate a dentist-delivered behavioural support intervention for ST cessation in Pakistan. The data suggested that the intervention may improve ST quit rates. The findings of this study will be useful in informing the design of future definitive studies.
