Aim: To explore whether the average price of houses per postcode sector [sector house average prices (SHAP)] is related to perinatal outcomes and whether gestational age would be lower and mortality higher in the least expensive areas compared to the most expensive. Methods: All neonatal unit admissions at King’s College Hospital from 1/1/2012 to 31/12/2016 were reviewed. The SHAP was retrieved from the Land Registry and the population was divided in equal quintiles with quintiles 1 and 5 representing the most and least expensive areas, respectively. Gestational age and birth weight z-score were collected. Mortality was defined as death before discharge from neonatal care. Results: Three thousand three hundred and sixty infants were included and divided in quintiles consisting of 672 infants. Gestational age was lower in quintile 5 compared to all other quintiles (adjusted P<0.001). Birthweight z-score was not significantly different between the quintiles. The SHAP was lower in the infants who died before discharge (n=92) compared to the SHAP of the infants who were alive at discharge (n=3268) (P<0.001). Infants of quintile 5 had 6 times higher risk of death before discharge from neonatal care compared to infants of quintile 1. Conclusions: Low SHAPs were associated with poorer perinatal outcomes suggesting SHAP could potentially be used in perinatal populations to determine socio-economic status and associated outcomes.
