In the AYLS cohort, high motor problem trajectory was also predicted by abnormal neonatal neurological status (OR, 1.69) and duration of hospitalization (OR, 1.02). Although neonatal complications (OR, 1.08) and poor parent-infant relationship (OR, 1.09) did not significantly predict high motor problem trajectory in the AYLS cohort, trends identified were comparable with those obtained from the BLS cohort.
“Most surprising was that one of the four risk factors that remained as independent predictors of high motor problem trajectory was poor parent-infant relationship,” Ms. Baumann said. “As far as we are aware, parent-infant relationship has not been previously reported as a predictor of poor motor development.”
She acknowledged certain limitations of the study, including the fact that nearly 33% of children could not be assessed throughout the study period because of dropout. “Families with children who had poor health and were socially disadvantaged were less likely to continue participation, and may even suggest that our findings have an even larger effect than reported,” Ms. Baumann said. “This is a problem that affects many longitudinal studies, and it may affect group comparisons. However, simulations have shown that even when dropout is selective or correlated with the outcome that predictions only marginally change (Br J Psychiatry. 2009;195[3]:249-56).”
She reported having no financial disclosures.
