Adiponectin levels measured in neonatal dried blood spot samples (DBSS) might be affected by both prematurity and being born small for gestational age (SGA). The aim of the study was to measure adiponectin levels in routinely collected neonatal DBSS taken on day 5 (range 3-12) postnatal from infants.
A retrospective case-control study.
One hundred and twenty-two infants: 62 very premature (34 SGA) and 60 mature infants (27 SGA). Adiponectin concentrations were determined in stored neonatal DBSS using a sandwich immunoassay based on flow metric Luminex xMap technology.
Adiponectin was measurable in all samples, and repeated measurements correlated significantly (r = 0.94). Adiponectin concentrations were negatively associated with both SGA (B = -0.283, P = 0.04) and prematurity (B = -2.194, P
