Low folate levels are a risk factor for schizophrenia regardless of gender

Key clinical point: Low levels of serum folate may be a risk factor for schizophrenia, irrespective of gender.

Major finding: Analysis of covariance by gender showed lower levels of serum folate in both male and female patients with schizophrenia (F [1, 716] = 140.6; P = 9.6 × 10−30 and F [1, 1088] = 191.6; P = 2.9 × 10−40, respectively) compared with the controls.

Study details: Serum folate levels were assessed in 482 Japanese patients with schizophrenia and 1,350 nonpsychiatric controls.
