Objective |
To examine cross-sectional relationships between biomarkers of environmental enteric dysfunction (EED), an acquired subclinical condition of the small intestine, and anthropometric and developmental outcomes among children in Lusaka, Zambia.
Study design |
Serum samples were collected from 240 children aged 27 to 35 months enrolled in a cluster-randomized trial assessing the effects of growth charts and small-quantity lipid-based nutrient supplements on linear growth. Samples were analyzed using the 11-plex Micronutrient and EED Assessment Tool, which incorporates 2 biomarkers of EED, namely intestinal fatty acid-binding protein (I-FABP), a marker of epithelial damage, and soluble CD14 (sCD14), a marker of microbial translocation. Associations between log2-transformed biomarker concentrations and anthropometric (height-for-age z-score [HAZ], weight-for-height z-score, and weight-for-age z-score) and developmental (Global Scales of Early Development development for age z-score and saccadic reaction time [SRT]) outcomes were assessed using linear regression analyses adjusted for background characteristics.
Results |
Mean ± SD HAZ was −1.94 ± 1.10. Higher sCD14 and I-FABP concentrations were significantly associated with lower HAZ (β: −0.21, 95% CI: −0.41, −0.01 and β: −0.20, 95% CI: −0.32, −0.08, respectively). Higher I-FABP concentrations were significantly associated with lower development-for-age z-score (β: −0.22, 95% CI: −0.40, −0.03) and slower SRT (β: 7.37 ms, 95% CI: 2.02, 12.72) as were higher alpha-1-acid glycoprotein concentrations (HAZ β: −0.38, 95% CI: −0.72, −0.03; SRT β: 11.14 ms, 95% CI: 0.94, 21.72).
Conclusions |
In children in Lusaka, biomarkers of EED were associated with poor anthropometric and developmental outcomes, underscoring the need for interventions to address EED to improve child health globally.
