Abstract
INTRODUCTION: Secondhand smoke (SHS) exposure poses risks to pregnant women and children. Though smoking among pregnant women in many low- and middle-income countries is low, exposure to SHS might be higher. We examined the prevalence and predictors of SHS among pregnant women from Costa Rica, the Dominican Republic, and Honduras. METHODS: Postpartum women 18+ years old who completed pregnancy in past 5 years were surveyed in health care and community settings. RESULTS: Data for 1,081 women indicated low tobacco use (1.0%-3.7%), frequent exposure to active smokers (29.0%-34.0%), often being close enough to breathe others' smoke (49.4%-66.5%), and most having smoke-free home policies (70.8%-76.2%). Women reporting unintended pregnancy (adjusted odds ratio [aOR]: 1.44, 95% confidence interval [CI] 1.03, 2.00) and alcohol consumption (aOR: 1.92, 95% CI 1.34, 2.77) were more likely to be close enough to breathe others' smoke. Women with health problems during pregnancy (aOR: 1.48 95% CI 1.07, 2.06) were more likely to have home smoking policies. Tobacco use was associated with all SHS exposure outcomes. CONCLUSIONS: SHS exposure was high during pregnancy; women with higher risk variables, that is, tobacco use, alcohol consumption, and unintended pregnancy were more likely to be exposed. Addressing SHS exposure in pregnancy in low- and middle-income countries can improve maternal health outcomes in vulnerable populations. IMPLICATIONS: The study results suggest a cluster of multiple risk factors associated with a high prevalence of exposure to SHS among pregnant women in LIMCs from Latin America and Caribbean Region. Interventions, regulations, and policies need to address specific high-risk factors to change behaviors and improve maternal and child health outcomes especially in vulnerable populations.
