Abstract
Early alterations in glucose homeostasis increase the risk of developing insulin resistance and obesity later in life. The concurrence of altered lipids and insulin sensitivity/resistance markers at birth has been scarcely investigated. The study aimed to ascertain level ranges of homocysteine (tHcyt), arylesterase (AE), lipids/lipoproteins, and insulin resistance/sensitivity markers in full-term neonates and to determine the concurrence effect of dyslipaemia and dysglycaemia on those parameters at birth. Participants were 197 full-term, 2.5 to <4.0 kg, without foetal distress Spanish newborns from the Mérida Study. Parameter percentiles for males and females were stated. The effect of the concurrence high glucose/high triglycerides (high glucose/high TG) or high glucose/low cholesterol transported by HDL (HDL-c) on tHcyt, LDL-c, HDL-c, lipoprotein (a) (Lp(a)), oxidised LDL (oxLDL), AE, glucose, insulin sensitivity (QUICKI) and insulin resistance index (HOMA-IR) was studied. Females had higher total cholesterol (TC), HDL-c, Apo A1, Lp(a) and HDL-c/Apo A1, but lower relative transport of TC (%TC) by the very low lipoprotein fraction than males. No gender differences were found for glucose, HOMA-IR and QUICKI. Neonates at the 2.5- to 2.999-kg range display more adequate HOMA-IR and QUICKI levels that their >3.0 kg counterparts. The concurrence of high glucose/high TG or high glucose/low HDL-c increased TC/HDL-c and HOMA-IR, but decreased, oxLDL, oxLDL/LDL-c and QUICKI with respect to that of low glucose/low TG or glucose/high HDL-c. The concurrence glucose/TG has predictive value for low QUICKI, whilst that of glucose/HDL-c for low QUICKI and high HOMA-IR, suggesting the importance of routine TG, HDL-c and glucose screening at birth as it would identify candidates for insulin resistance.
