I due studi non sono in contrapposizione. il secondo non prende in considerazione il lutto della madre fra i fattori di rischio prenatali. Cito testualmente: Perinatal risk factors. The perinatal factors investigated were categorized as 1) delivery and newborn characteristics: fetal presentation, mode of delivery, Apgar score at 5 minutes, birth weight, gestational age at birth, and weight for gestational age; 2) pregnancy characteristics: multiple gestation, preeclampsia, and number of antenatal visits; and 3) parental characteristics: number of previous pregnancies, maternal smoking reported at the first antenatal visit, maternalcitizenship, and maternal and paternal ages. Birth weight for gestational age was categorized into three groups according to the gender-specific birth-weight distribution at a given gestational age in a sample of children (N = 97,596) born in Denmark between 1980 and 1994: small for gestational age (<10th centile), appropriate for gestational age (10th90th centile), and large for gestational age (>90th centile). Information about Apgar score, gestational age at birth, and birth weight for gestational age was available from 1978 only; information about preeclampsia and maternal smoking was collected for only the years 19781990 and 19911994, respectively.
