“…[ 28 ] Other studies also found decreased Cr stores in multiparous women, highlighting the depletion of body Cr stores in pregnancy. [ 29 30 31 ] A study by Morris et al . [ 32 ] tries to evaluate the effect of pregnancy on urinary excretion of Cr and if there is any subsequent alteration in insulin sensitivity.…”

The topic of maternal Chromium (Cr) levels in Gestational Diabetes Mellitus (GDM) has remained controversial; some studies have found lower levels of Cr in GDM population, whereas others found no significant changes in Cr status in GDM. Therefore, this systematic review and meta-analysis was aimed at qualitatively and quantitatively synthesizing past studies to find the relationship of maternal Cr levels with GDM. The study protocol was registered at International prospective register for systematic reviews (PROSPERO) (ID CRD42021272979). Strict adherence to the Preferred Reporting Items for Systematic review and Meta-analysis checklist, 2009 was followed during the entire study. Random-effect model for calculation of distribution of true effect sizes was used for the meta-analysis with a confidence interval (CI) of 95%. The pooled Standard Mean Difference of control and GDM groups were compared using Z statistics with a P value of <.05 as significant. Six studies were included for the systematic review and four studies entered meta-analysis. The test of overall effect revealed that the pooled Cr values did not differ significantly between controls and GDM group (Z = 1.52, P =0.13). Heterogeneity between the studies was high (I 2 = 97%). A subgroup analysis revealed that results varied as per place of study, trimester of pregnancy, and Cr estimation technique. Results from meta regression analysis revealed that sample size of individual studies (Q = 0.003, P =0.67) and year of publication of studies (Q = 0.22, P =.48) had no significant effect on the overall Standard Mean Difference. Factors such as ethnicity, lack of history of infection, and diet history can influence the results of this study.

“…In addition, the following results have been reported concerning other metals and environment: a decrease in maternal hair Cr concentration with an increase in the number of deliveries, age at delivery, and months of gestation; 21,22) significantly high Se levels in the hair of learning-disabled children when compared to controls;23) and low hair Se levels in Keshan disease in China, which is characterized by abnormal cardiac function which has recently attracted attention. Each hair sample was cut into length of approximately 1cm length, and if they were oily or greasy, they were then washed with acetone and air dried.…”

It was shown that x‐ray fluorescence is very suitable for following changes in trace element concentrations in the hair of pregnant women. Two hundred hair samples were analysed, mean concentrations for Cr, Mn, Fe, Cu and Zn were evaluated quarterly and their distribution according to weeks of pregnancy was determined. Possibilities of using longitudinal hair analysis with the purpose of following the concentrations of some particular microelements in the course of pregnancy are discussed.
