Smokeless tobacco (SLT) use in Pakistan is a significant public health issue. While knowledge and attitudes are adequate, factors like cigarette substitution and flavors drive usage, with many users desiring to quit.
Area of Science:
- Public Health
- Tobacco Control
- South Asian Health
Background:
- Smokeless tobacco (SLT) is consumed orally or nasally and accounts for one-third of tobacco use in South Asia.
- Limited empirical research exists on SLT prevalence and influencing factors in Pakistan.
- This study assessed knowledge, attitudes, and usage of SLT in Pakistan.
Purpose of the Study:
- To assess the knowledge, attitudes, and usage of smokeless tobacco (SLT) in Pakistan.
- To identify factors influencing SLT consumption and inform targeted interventions.
- To understand public health challenges associated with SLT in the Pakistani community.
Main Methods:
- A cross-sectional online survey was conducted across Pakistan.
- A comprehensive questionnaire, incorporating elements from Global Adult Tobacco Survey, was used.
- Data analysis involved descriptive statistics and logistic regression using SPSS v26.
Main Results:
- 85.86% of 1,195 participants had heard of SLTs; 72.55% recognized health risks, but 30% lacked knowledge on legality.
- Negative health effects were the primary deterrent (60.33%).
- Key usage drivers included use as a cigarette alternative (OR 4.45) and availability in preferred flavors (OR 2.27); 69.82% of current users wanted to quit.
Conclusions:
- Despite adequate knowledge and attitudes, SLT use remains a public health concern in Pakistan.
- Understanding myths, incentives, and deterrents is crucial for developing effective interventions.
- Targeted strategies are needed to reduce SLT use and associated health risks in the Pakistani community.
