Association Between Particulate Matter Exposure and Thyroid Hormone Levels in Early Childhood: Results From JECS

Using a large sample, the statistical modeling results suggested an opposite association between PM exposure and fT4. However, since this association is very weak, from a clinical and epidemiological point of view, we can entirely ignore the effect of PM exposure on fT4. Therefore, we conclude that PM does not significantly influence thyroid parameters in daily life.
