Maternal mortality is a serious issue in the developing world due in part to inadequate care and awareness before, during, and after the pregnancy period. Appropriate information about maternal healthcare is essential to reduce maternal mortality. Mass media can be an influential source in disseminating knowledge and information on maternal healthcare. Therefore, this study examines the impact of mass media exposure (television, radio, and newspaper) and socioeconomic factors on maternal healthcare utilization in four South Asian countries: India, Bangladesh, Nepal, and Afghanistan. Analyses use the Demographic and Health Survey 2014-2016, a nationally representative survey of women aged 15-49 years. Maternal healthcare utilization is significantly higher among women exposed to mass media across countries, even after controlling for mother’s, husband’s, and household socioeconomic factors. Mother’s educational attainment moderates the association between mass media and maternal healthcare in three of the four countries.
