Minor Physical Anomalies in Japanese Patients With Schizophrenia Minor Physical Anomalies in Japanese Patients with Schizophrenia

We assessed the prevalence of minor physical anomalies (MPAs) in Japanese patients with schizophrenia (n=313) and normal controls (n=128) using the Waldrop scale. There was a significant difference in the scale scores between the patients with schizophrenia and control subjects (U=17274.5, p=0.02). Patients had significantly more MPAs than controls on the individual scale items of malformed ears (p=0.039), furrowed tongue (p=0.006), high steepled palate (p=0.041) and head circumference which was 1.5 SDs below the average of normal controls (p=0.015). When we defined subjects at or above the median MPA score to be in the high anomaly group, significantly more patients than normal controls were represented in this group (p=0.033). Waldrop scores were not found to be related to age at onset of schizophrenia.
