Therefore, we aimed to examine the socioeconomic inequalities in receiving VAS among children aged 6-59 months within and between 11 South and Southeast Asian countries.</p><p><strong>Methods: </strong>We used population-representative cross-sectional data from the demographic and health surveys conducted between 2003 and 2022 for 11 South and Southeast Asian countries (Afghanistan, Bangladesh, Cambodia, India, Indonesia, Maldives, Myanmar, Nepal, Pakistan, Philippines and Timor-Leste).
