title: Physical ill health and risk of psychosis.
abstract: Patients with psychosis have been found to suffer from physical illnesses more commonly than the general population. In this report, self-reported physical ill health and its correlates among subjects with and without vulnerability to psychosis in a sample of first-degree relatives, help-seekers and controls were investigated. Perceived physical health was statistically significantly poorer among subjects with minor symptoms on the Structured Interview for Prodromal Symptoms and those vulnerable to psychosis than among those without symptoms measured by 13 somatoform symptom sum scores of the Symptom Checklist-90. Those at current risk of psychosis had a significantly higher mean sum score on the 13 somatic items (mean=21.1) than others (mean=9.6). Having physical symptoms or a self-reported physician-diagnosed illness was significantly associated with vulnerability to psychosis (odds ratio=3.05). The subjects with a mood disorder (odds ratio=4.33) had significantly more commonly physician-diagnosed illnesses than those who had no diagnosis or any other diagnosis. Physical ill health seems to be common among those vulnerable to psychosis.
