Where Do Smokers in Singapore Smoke? A Latent Class Analysis to Classify Smokers Based On Smoking Location

This study identifies three distinct smoker subgroups based on smoking locations-at work, outside the home, and everywhere-offering actionable insights for targeted interventions. Workplace-based cessation efforts can focus on those smoking at work, while promoting smoke-free homes may address familial pressures in the outside-home group. For those smoking everywhere, intensive interventions are needed to reduce SHS exposure across settings. Multinomial regression reveals that familial disapproval, ethnicity, and housing type significantly influence smoking patterns, highlighting the importance of culturally tailored interventions that leverage social, familial, and environmental factors to reduce smoking prevalence and SHS exposure.
