Open access · cc by · source: Europe PMC
Among 65,561 LASI adults, 38% had used any tobacco; 22.8% ever and 20.4% currently used smokeless tobacco, with higher use in rural, male, poorer, ST, and informal/agricultural work.
How this study connects
Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
In older Indian adults, smokeless tobacco is common and clusters in rural, male, poorer, and informal work.
LASI wave 1 (n=65,561) found 38% ever tobacco use; 22.8% ever and 20.4% currently used smokeless tobacco. Among tobacco users, 51% used SLT, 40% smoked, and 9% used both. Use was higher in Scheduled Tribe groups and in agricultural/plant-machine work (~22%) than among professionals (~10%); 88.6% of ever-SLT users still used it.
Evidence for the claim as stated.
India’s tobacco epidemic rose then fell for men while women declined, with huge state gaps and smokeless still common.
NFHS rounds showed age-standardized male tobacco use rising 32% from 1998–99 to 2005–06 (27.90% to 36.81%) then falling 26% by 2015–16 (to 27.31%); women’s use declined throughout. By 2015–16 male smoking was 12.20% and smokeless 15.12%, with male smoking from 5.71% (Maharashtra) to 37.70% (Mizoram).
Scope note — LASI older-adult SLT occupation prevalence — not NFHS 15–49 time-trend smoking vs smokeless
Limits the claim's scope: a different population, assay, or outcome.
Smokeless-tobacco prevalence by occupation in India is not a smoked-cigarette CVD risk function and is not a secondhand-smoke Burden of Proof synthesis. Product, population, and outcome all differ.
Evidence for the claim as stated.
National NFHS time trends, LASI occupational SLT prevalence, and smoked-tobacco CVD relative risks describe different products, ages, and outcomes.

Who uses smokeless tobacco in India’s LASI sample?
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
From 65,561 adults, 38% used smoked or smokeless tobacco.
From the sample size of 65,561, 38% have used either smoking or smokeless tobacco.
Population-level SLT: 22.8% previous and 20.4% current users.
At the population level, 22.8 and 20.4% are previous and current users of smokeless tobacco, respectively.
Key findings
Of tobacco users, 51% used SLT, 40% smoked, 9% both. Population-level previous/current SLT: 22.8% and 20.4% (14,090 and 12,461). 88.6% of SLT users still used it (11.4% quit). ST groups had the highest shares (31.6% previous, 28.4% current). Professionals ~10%; plant/machine and agricultural workers ~22%. Authors urge quitting programs for rural male informal workers.
Methodology
Analyzed LASI wave 1 (2017–18) with survey weights, describing ever/current smokeless tobacco (SLT) and fitting multivariable logistic models for occupation, employer type, workplace, business, workload, and childhood adversity.
Limitations
Cross-sectional LASI cannot prove occupation causes SLT use; self-report and healthy-survivor older adults may bias prevalence, and causality of childhood adversity is not established.
