Abstract
Objective
The paper describes the pattern of exposure to second-hand smoke (SHS) at home among the adult population of Vietnam and examines associated socio-demographic factors.
Methods
A total of 11,142 households were selected for this survey using a two-phase sampling design analogous with three-stage stratified cluster sampling. The dependent variable was the status of exposure to SHS at home. Independent variables included gender, age, occupation, asset-based wealth quintile, ethnicity, marital status, residence. Logistic regression modelling was performed to examine the association with relevant factors of patterns of exposure to second-hand smoke among non-smokers.
Results
Of adults aged 15 years and above (representing approximately 47 million people) 73.1% reported they were exposed to SHS at home at least monthly. Considering non-smokers only, the prevalence of exposure to SHS at home was 67.6% (equivalent to approximately 33 million non-smokers). The significant correlates of the status of exposure to SHS at home among non-smokers were female gender, ethnic minority, low education, and lack of smoking restriction at home.
Conclusion
The study showed that a high percentage of people are exposed to second-hand smoke at home. Disadvantaged people were more likely than the better-off to be exposed to SHS at home.
