About this study

Official title: Health Warnings and Counseling at Primary Health Care Centers for Smoking Cessation and NCD Prevention: A Randomized Controlled Trial in Bangladesh and Pakistan

Tobacco use remains persistently high across South Asia, despite numerous public health efforts, and continues to significantly contribute to the burden of non-communicable diseases (NCDs) such as cardiovascular disease, hypertension, diabetes, and stroke. Community pharmacists-widely accessible and trusted within their communities-are an underutilized resource for delivering public health interventions. Graphic health warnings (GHWs), recommended by the World Health Organization (WHO), have been shown to promote smoking cessation, but are rarely paired with personalized counseling by healthcare providers.

This study aims to evaluate both the effectiveness and cost-effectiveness of integrating GHWs with pharmacist-led personalized counseling at primary healthcare pharmacies in Bangladesh and Pakistan. A cluster randomized controlled trial (RCT) will be conducted, enrolling 3,240 adult participants in Bangladesh and ~160 participants in Pakistan (for feasibility study) from community pharmacies. Participants will be randomly assigned to one of three groups: (1) GHW only (distribution of printed booklets); (2) GHW + counseling (pharmacist-led counselling sessions based on booklets at baseline and six months, with monthly SMS reminders); or (3) standard care (usual pharmacy services with no additional materials).

The intervention includes twice-yearly counseling sessions-delivered both in-person and digitally-supported by educational booklets and leaflets. The primary outcome is self-reported 7-day point prevalence abstinence at 12 months (validated where feasible). Secondary outcomes include reduction in cigarettes per day, quit attempts, readiness to quit, awareness of tobacco harms, diet and physical activity scores, quality of life, blood pressure control among hypertensive participants, and cost-effectiveness. Feasibility outcomes in Pakistan include recruitment rate, participant retention, intervention fidelity and acceptability. Bayesian statistical models will be used to assess efficacy, and economic evaluations will determine the cost-effectiveness of the interventions. The findings aim to inform scalable public health strategies for tobacco control and NCD prevention in resource-limited settings.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Graphical health warningsBehavioural

    This group will receive only graphical health warnings (GHWs) featuring images proposed by the Bangladesh Tobacco Control Cell, explicitly illustrating smoking-related harms, such as mouth diseases, damaged teeth and gums, lung diseases and cancer, heart diseases and cardiovascular damage, and throat and oral cancer. Additionally, these warnings will clearly highlight the benefits of quitting smoking-including improved overall health, reduced disease risks, financial savings, and enhanced quality of life-as well as practical cessation techniques. Participants will receive these GHW materials at baseline and again at the six-month follow-up to reinforce these critical health messages; however, this intervention group will not receive any counselling services. Monthly SMS reminders will also be sent to participants, prompting them to review the GHW leaflet and reinforcing the negative health impacts of smoking and the benefits of quitting.

  • Graphical health warnings plus pharmacist-led counsellingBehavioural

    Participants in this group will receive graphical health warnings (GHWs) featuring Bangladesh Tobacco Control Cell-approved images clearly depicting smoking-related harms (e.g., mouth diseases, damaged teeth and gums, lung cancer, heart disease, and oral cancer). Additionally, they will receive personalized counselling from community pharmacists, focused on the specific health and financial benefits of quitting, practical cessation techniques, strategies for overcoming barriers, and relapse prevention. This combined intervention will be provided at baseline and reinforced at a six-month follow-up. Monthly SMS reminders will also be sent, reinforcing key messages on the harmful effects of smoking and benefits of cessation.

  • Routine pharmacy services (no intervention)Other

    Participants in this group will receive only routine pharmacy services based on standard pharmacy practice guidelines applicable in each country. They will not receive any additional graphical health warnings or counselling interventions. Outcomes will be assessed at baseline, 6 months, and 12 months, consistent with the intervention groups.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Self-reported 7-day point prevalence abstinence

    The primary outcome is self-reported 7-day point prevalence abstinence at 12 months. Will be measured by percentage of participants who report smoking cessation

    Measured: 6 months and 12 months post-intervention.
