Schizophrenia is a complex mental disorder with genetic and environmental components. Obstetric complications (OCs) are one of the most common environmental risk factors described. However, despite being different in timing and outcome, OCs are usually described as a homogeneous entity. In the present study, we evaluate the presence of different patterns of OCs evaluated with the Lewis-Murray Scale in chronic schizophrenia patients (n = 101) and their association with a crude marker of the intrauterine environment such as weight at birth.OCs related with abnormal fetal growth (p < 0.001) and OCs during gestation (p = 0.003) were associated with lower birth weight. However, difficulties in delivery, complications in pregnancy, and OCs all together (as a set) were not associated with weight at birth.Our results infer that OCs cannot be taken as a homogeneous group. Different patterns of OCs result in different birth weights, which is associated with specific metabolic, cognitive, and brain structure outcomes.
