Abstract [en]

Objective: To investigate the repeatability of maternal self-reported prenatal, perinatal and early postnatal factors within the IDEFICS (Identification and prevention of dietary-and lifestyle-induced health effects in children and infants) study. Design: Data are from the baseline survey of the longitudinal cohort study IDEFICS in eight European countries. Subjects: A total of 420 parents from eight countries (43-61 per country) were asked to complete the parental questionnaire (PQ) twice at least 1 month apart. Measurements: The PQ assesses prenatal (maternal weight gain), perinatal (child's birth weight and length, Caesarean (C)-section, week of delivery) and early postnatal factors (exclusive breastfeeding, breastfeeding, introduction of solid food). Intra-class correlation coefficients (ICCs) were calculated to compare maternal reports on prenatal, perinatal and early postnatal factors between the first and second PQ. Results: In total, 249 data sets were considered for the analyses. Overall, maternal reports for prenatal and perinatal factors showed higher repeatability (ICC = 0.81-1.00, P <= 0.05 for all) than those for early infant nutrition (ICC = 0.33-0.88, P <= 0.05 for all). Perfect agreement was found for parental reports on C-section (ICCall = 1.00, P <= 0.05). There was stronger agreement for duration of breastfeeding (ICC = 0.71, P <= 0.05) compared with exclusive breastfeeding (ICC = 0.33, P <= 0.05). Maternal reports showed moderate correlation for the introduction of several types of food (cereals ICC = 0.64, P <= 0.05; fruits ICC = 0.70, P <= 0.05; meat ICC = 0.83, P <= 0.05; vegetables ICC = 0.75, P <= 0.05), and high correlation (ICC = 0.88, P <= 0.05) for cow's milk. Conclusion: Maternal reports on pregnancy and birth were highly reproducible, but parental recall of early infant nutrition was weaker and should be interpreted more cautiously.
