Understanding Discrepancies in Nutritional Outcomes Among Under-Fives in Laos: A Mixed-Methods Study Using the Positive Deviance Approach

Background: Stunting is one of the main contributing factors in the under-five mortality rate worldwide. In Laos, the prevalence of stunting remains high, particularly in mountainous rural areas. To prevent stunting, insight into positive deviant behaviors can help understand how people can cope or adapt in resource-poor settings. Objective: This study aims to analyze the practices and underlying factors that explain discrepancies in nutritional outcomes in children under the age of 5 in remote mountainous areas in Laos. Methods: This mixed-methods study included all children under the age of 5 living in 6 selected villages. Anthropometric measurements were taken, and a Z-score for stunting was calculated to select the positive and negative deviant children. To identify the causes of discrepancies in childhood stunting, household questionnaires, focus group discussions, observations, and individual interviews with family members and health workers were conducted. Results: Fifty-five percent of children were stunted. Inappropriate care and feeding practices were observed such as providing unbalanced diets and not attending health facilities. Positive deviant mothers were less likely to follow inappropriate practices, experienced less food insecurity, and had higher motivation and autonomy, which resulted in prioritizing their children's health. An active role of fathers seemed to benefit positive practices within households. Conclusions: The combination of many different practices in which positive deviant families are doing slightly better resulted in less stunting of children. Those practices are related to the household resources, such as access to food and social support; and the mother's motivation, autonomy, and perspectives on child health.
