Objective:The objective of the study was to examine normal variations of umbilical cord arterial pH by gestational age (GA).Study Design:Population-based cohort study of 46 199 infants born from 2008 to 2014 in Stockholm, Sweden, with GA 28 to 42 weeks, Apgar score ⩾7 at 5 min, non-instrumental vaginal delivery, and birth weight for GA⩾3rd and ⩽97th percentile. Quantile regression was used to investigate the associations between GA and infant sex, and pH.Results:The mean umbilical cord arterial… CONTINUE READING
