Babies born with a low birth weight (LBW) have a fourfold higher risk of dying within the first 28 days of their life compared with babies born with a normal weight. In Indonesia, the prevalence of LBW were 11.1% in 2010 and 10.2% in 2013. LBW is the second most common type of tobacco-use-related outcome. Most active smokers ignore the risks and hazards of secondhand smoke exposure to those around them. As much as 57% of households in Indonesia have at least one smoker, and 91.8% of them smoke in the household. The purpose of this study was to determine the effect of passive cigarette smoke exposure in households on the incidence of LBW. This case-control study used Basic Health Research (Riskesdas) data from all over Indonesia. Logistic regression analysis was used to assess the magnitude of the effect. The results showed that passive smoking in the household was associated with the risk of LBW incidence with adjusted ORs of 1.56 (95% CI: 1.37–1.76) on exposure to less than 20 cigarettes and 1.50 (95% CI: 1.22–1.84) on exposure to 20 cigarettes or more after being controlled by confounding variables. In addition, it was also found that the other risk factors for LBW incidence were low maternal education (OR: 1.26; 95% CI: 1.01–1.57) and ANC frequency that was not standard (OR: 1.19; 95% CI: 1.04–1.36). It is recommended that regulations be imposed to control smoking behavior in the household.
