Abstract
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.

期刊介绍:
The Journal of Pediatrics is an international peer-reviewed journal that advances pediatric research and serves as a practical guide for pediatricians who manage health and diagnose and treat disorders in infants, children, and adolescents. The Journal publishes original work based on standards of excellence and expert review. The Journal seeks to publish high quality original articles that are immediately applicable to practice (basic science, translational research, evidence-based medicine), brief clinical and laboratory case reports, medical progress, expert commentary, grand rounds, insightful editorials, “classic” physical examinations, and novel insights into clinical and academic pediatric medicine related to every aspect of child health. Published monthly since 1932, The Journal of Pediatrics continues to promote the latest developments in pediatric medicine, child health, policy, and advocacy.
Topics covered in The Journal of Pediatrics include, but are not limited to:
General Pediatrics
Pediatric Subspecialties
Adolescent Medicine
Allergy and Immunology
Cardiology
Critical Care Medicine
Developmental-Behavioral Medicine
