[BDSP. Notice produite par INIST xR0xiOdJ. Diffusion soumise à autorisation]. Objective. To describe the methods used at birth to recruit a population-based cohort of newborns of all birthweights at higher risk of having a chronic condition, and to present baseline results. Methods. Screening of all newborns at hospital discharge for five non-exclusive criteria : (1) low birthweight (LBW), (2) congenital anomalies or genetic disease, (3) specified conditions associated with a high probability of chronicity, (4) referral to a neonatal intensive care unit (NICU), (5) or defined social problems. Calculation of Hobel risk scores for children satisfying 1 criterion. Subjects. All 6477 live births delivered in the 19 maternity hospitals of a geographically defined region (Vaud, Switzerland) to resident mothers in 1993-1994. Results. Twelve per cent (n=760) of newborns met 1 criterion : 6.3% of all newborns had an LBW (criterion 1), 2.4% had a birth defect, 0.9% met criterion (3), 4.4% stayed in an NICU and 1.6% had serious social problems. Hobel prenatal score was high ( 10 points) for 41% of children with 1 criterion, the intrapartum score for 87% and the neonatal score for 68%. Conclusions. Most newborns identified by the above simple criteria also had elevated perinatal risks. (...)
