More than half of women of reproductive age in India are anemic. This study investigates the role of interpersonal communication in increasing the consumption of iron-folic acid supplements. Interventions that increase interpersonal communication may influence and empower individuals and the larger community in promoting behavior change. This investigation uses data from a cluster randomized intervention to understand the pathways by which interpersonal communication mediates the consumption of iron-folic acid supplements. Longitudinal data from control and intervention arms in rural Odisha, India, were collected at baseline (N = 3,691) and 20 months later at end-line (N = 3,394). Structural equation models highlighted the positive role of interpersonal communication in mediating iron-folic acid supplement use. This study illustrates that even during social distancing due to COVID-19, strategic interpersonal communication can improve iron-folic acid supplement use. Our results elucidate two key interpersonal communication pathways at play, namely the ritualistic and instrumental pathways in improving health behavior change in the community.
