Associations of childhood and current secondhand smoke exposure at home with current secondhand smoke exposure at work: A cross-sectional analysis of the Singapore multi-ethnic cohort.

Introduction: Relationships between secondhand smoke exposure (SHSE) in various temporal and physical settings are not fully studied despite its adverse impacts on human health, especially in multi-ethnic Asian populations. We investigated associations of childhood and current SHSE at home (SHSE) with current SHSE at work (SHSE) in Singapore and its relation to sources of daily smokers at home.

Methods: This cross-sectional study identified 925 healthy, never smoker working adults from the Singapore Multi-Ethnic Cohort (2004-2010).

Determinants of Hardcore Smoking in a MULTI-ETHNIC Study of Cigarette Smokers in Singapore.

Smokers who are resistant to quitting are not well studied in Asia, particularly in multi-ethnic populations. We compared the characteristics of hardcore smokers in Singapore, a multi-ethnic Asian population, with other daily smokers, and investigated the role of ethnicity as an effect modifier on identified determinants, including cigarette flavor preferences, using cross-sectional data from Singapore Smokers' Survey (n = 1,501). Multivariable logistic regression was used to assess the association.
