blood insulin levels in our study. Secondly, cord blood insulin concentrations decrease if collected in heparin and stored at room temperature [1]. But in our study, the samples were collected in EDTA and immediately refrigerated. The third explanation could be the pulsatile release and shorter half-life of insulin coupled with its possible fluctuations during delivery [1]. To conclude, neither neonatal anthropometry nor cord insulin levels show sexual dimorphism at birth among Indian children. Being an observational cross-sectional study with limited sample size, our results need validation from larger studies.
