Hemoglobin as a mediator between air pollution and growth outcomes in children under 60 months: the moderating role of nutritional supplementation.

ABSTRACT:

Background

Prior research has yielded incongruent results about the association between air pollutants and offspring hemoglobin levels, as well as between air pollutants and child development. This may be because previous studies have not taken both air pollution and nutrition into account. This study sought to examine the correlations between postnatal exposure to air pollution (PM_2.5, PM₁₀, SO₂, and CO), offspring hemoglobin levels, stunting, and underweight. Furthermore, we investigated whether hemoglobin levels mediate these connections and assessed the moderating influence of dietary supplementation on hemoglobin levels and growth outcomes.

Methods

A unified nutrition package intervention study was conducted in western, China between 201
