Anemia and stunting in children are detrimental to the prospects of a normal, healthy upbringing. Having similar risk factors and serious consequences, the syndemic aspect of these two ailments is mostly underrated, and positive deviant (PD) factors that ensure non-anemic status in stunted children have not been studied to date.

This study aimed to identify PD factors that have potential to prevent syndemic anemia among stunted children aged 6–59 months in Myanmar. This was a cross-sectional secondary analysis of the Myanmar Demographic and Health Survey (DHS) data conducted in 2016, applying the PD concept, where children who were stunted without anemia were considered as PDs.

Among 1248 stunted children, those who had the syndemic condition were compared with their PD peers in terms of maternal characteristics as well as socioeconomic and health-related factors. Multivariable logistic regression analyses were used to identify the determinants of syndemic state. The results showed that three out of every five stunted children were anemic. The syndemic risk was decreased among children of maternal age groups 20–34 years and 35–44 years: [aOR] = 0.19, 95% CI = 0.05–0.69; p = 0.012, and aOR = 0.19, 95% CI = 0.05–0.75; p = 0.018, respectively. Moderately stunted children (aOR = 0.53, 95% CI = 0.34–0.81; p = 0.004) and children who were not currently breastfed (aOR = 1.56, 95% CI = 1.01–2.41; p = 0.044) were less likely to develop the syndemic condition.

Maternal age, stunting severity, breastfeeding duration, and maternal anemic status are strong predictors in determining hemoglobin concentrations among stunted children. This study suggests that nutritional interventions targeting PD factors could represent syndemic action in improving child health.
