Abstract: This study examines whether exposure to secondhand smoke (SHS) increases the risk of acute respiratory infections (ARI) among children aged 0-59 months. Study utilized nationally representative data from National Family Health Survey (2015-2016), which adopted two-stage stratified random sampling. Four mutually exclusive groups based on the type of cooking fuel usage and SHS exposure were created. Descriptive statistics and multivariate logistics regression analysis were applied. At the national level, 10.5% prevalence of ARI was reported during 2015-2016. About 47.9% (95%CI 47.7-48.2) of households was exposed to SHS and used solid biomass fuel for cooking. Nearly, 20.7% of households with clean fuel usage was exposed to SHS. Regression analysis suggests that the likelihood of ARI among children who were living in households with solid biomass fuel usage and exposed to SHS was 11% (95%CI 1.06-1.17) greater than children living in households with clean fuel usage with no SHS exposure. Moreover, our results further revealed that the odds of ARI among children living in households with clean fuel but exposed to SHS were 19% (95%CI 1.13-1.25) higher than the children living in the household with no SHS exposure and clean fuel use. Children living in households exposed to SHS are at higher risk of ARI.
