Serum selenium and growth outcomes
LBW
In line with our observations for WBSe, we found similar trends for associations between serum Se at delivery and growth measures, although associations were small and non-significant. Risk ratios were also higher for SGA and LBW per unit increase in serum Se concentrations. Similar to results for WBSe, associations between serum Se and birth weight were also negative and large in magnitude (3–28 g decrease in birth weight per unit increase in serum Se), although these findings were not significant and confidence intervals for effect estimates were wide.
