Unravelling sociodemographic inequities in household secondhand smoke exposure among non-smokers in Malaysia: A secondary analysis of National Health and Morbidity Survey (NHMS) 2019.

ABSTRACT:

Introduction

Secondhand smoke (SHS) exposure remains a significant global public health issue. Identifying the factors contributing to SHS exposure is crucial for developing targeted, evidence-based interventions to mitigate its impact. This study examines the patterns and determinants of SHS exposure at home among non-smoking Malaysians.

Methods

Data were derived from the National Health and Morbidity Survey (NHMS) 2019, which employed a cross-sectional design and multistage sampling to gather a representative sample of Malaysians aged ≥15 years. Demographic data and information on SHS exposure at home within the past month, were collected via a structured questionnaire. Weighted data were analyzed using chi-square tests and multivariable logistic regression.
