A Mixed-Method Study of Unhealthy Feeding Practices Among Mothers of Children Aged 6–23 Months from an Internally Displaced Person Camp, Kayin State, Myanmar

Background/Objectives: Conflict-driven displacement can disrupt food environments, health services, and caregiver practices, increasing the risk of unhealthy feeding behaviors among young children. Evidence from ethnic internally displaced populations (IDPs) in Myanmar remains scarce. This study examined the prevalence and determinants of unhealthy feeding practices among IDP mothers of children aged 6–23 months. Methods: A sequential explanatory mixed-method study was conducted among 617 mothers in Karen ethnic IDP camps in Myanmar. Structured interviews were used to assess mother-reported zero vegetable or fruit consumption (ZVF) and unhealthy food consumption (UFC) among children, and multivariable logistic regression identified associated factors. Subsequently, six focus group discussions explored contextual influences on feeding practices and were analyzed via thematic analysis. The findings were integrated using a joint display approach. Results: A total of 29.2% of children experienced ZVF, while 57.5% consumed unhealthy foods. Mothers who attended fewer than the recommended antenatal care (ANC) visits were more likely to report both ZVF (AOR = 1.968, 95% CI: 1.297–2.988) and UFC (AOR = 1.830, 95% CI: 1.265–2.649). Higher maternal decision-making autonomy was also associated with increased odds of ZVF (AOR = 1.757, 95% CI: 1.031–2.995) and UFC (AOR = 1.606, 95% CI: 1.040–2.481). Other associated factors included child age, household income, family structure, paternal employment, and household dietary practices. Qualitative findings identified six themes influencing feeding practices: “familiarity breeds acceptance”, “traditional beliefs and food restrictions”, “constrained local food environments”, “time constraints and convenience feeding”, “preference for sweet foods”, and “disrupted access to health and nutrition services”. Conclusions: Unhealthy feeding practices were common in this displaced population. Greater maternal decision-making autonomy was not necessarily associated with healthier feeding practices, highlighting the importance of nutrition literacy and supportive food environments. Community-based nutrition interventions may help improve complementary feeding practices in conflict-affected settings.
