Prevalence of food insecurity in community‐dwelling people living with severe mental illness.

Aim: The present study aimed to measure the prevalence and severity of food insecurity in people with a severe mental illness, defined as schizophrenia and related psychoses, and bipolar disorder; and explore relationships between food insecurity status, and sociodemographic and clinical characteristics. Methods: This cross‐sectional study recruited community‐dwelling people with severe mental illness receiving clozapine and/or a long‐acting injectable antipsychotic medication within three mental health services in Sydney, Australia. Participants completed the 18‐item Household Food Insecurity Access Scale. Sociodemographic and medical information was obtained from participants' medical records. Independent samples t‐test and chi‐square analyses were used to test for between group differences based on food insecurity status. Binary logistic regression analyses adjusting for age and gender were used to determine the odds ratio. Results: One‐hundred and eighty‐eight people completed the assessment: 63% were male, mean age was 49.2 ± 12.4 years, and the majority (85%) had a diagnosis of schizophrenia. Food insecurity was detected in 31% of participants. Of those who were food insecure, 12% were classified as severe, 13% as moderate and 7% as mild. Tobacco smoking was higher in food insecure people compared to food secure people (odds ratio = 3.1, 95% CI 1.3 to 7.1, p = 0.01). Food insecurity status was not associated with demographic, diagnostic or other clinical data. Conclusions: Food insecurity is highly prevalent among community‐dwelling people with severe mental illness receiving clozapine and/or long‐acting injectable antipsychotic medication. Food security screening should be considered as routine care for this population group. [ABSTRACT FROM AUTHOR]
