| Abstract: | Objective : To derive newborn percentile charts using NSW population and hospital-based data. Methodology : Birthweight data for liveborn singleton infants were obtained from the New South Wales Midwives Data Collection (MDC) from 1990 to 1994 inclusive ( n = 422139). Data were also collected from King George V Hospital (KGV) for liveborn singleton infants less than 35 weeks of gestation for 1982-89 inclusive, and for all gestations for 1990-95 inclusive ( n = 30 610). Birthweight percentiles were derived using the MDC data separately for mates and females. Head circumference ( n = 29 090) and birth length percentiles ( n = 26 973) were derived from the KGV data. Results : The charts derived from MDC data had generally higher percentiles than previously published charts. These represent the largest Australian population-based study published to date. Conclusions : Periodic review of newborn growth charts is recommended because of changing ethnic and socio-economic factors. |
