People with severe mental illness (SMI) have numerous risk factors that may predispose them to food insecurity (FI); however, the prevalence of FI and its effects on health are under-researched in this population. The present study aimed to describe the prevalence of FI and its relationship to lifestyle factors in people with SMI. This cross-sectional study recruited people with SMI receiving long-acting injectable (LAI) antipsychotic medication from community services at three sites in Sydney, Australia. Assessments were completed on physical health and lifestyle factors. χ2 Tests, independent-samples t tests and binary logistic regression analyses were calculated to examine relationships between lifestyle factors and FI. In total, 233 people completed the assessments: 154 were males (66 %), mean age 44·8 (sd 12·7) years, and the majority (70 %) had a diagnosis of schizophrenia. FI was present in 104 participants (45 %). People with FI were less likely to consume fruits (OR 0·42, 95 % CI 0·24, 0·74, P = 0·003), vegetables (OR 0·39, 95 % CI 0·22, 0·69, P = 0·001) and protein-based foods (OR 0·45, 95 % CI 0·25, 0·83, P = 0·011) at least once daily, engaged in less moderate to vigorous physical activity (min) (OR 0·997, 95 % CI 0·993, 1·000, P = 0·044), and were more likely to smoke (OR 1·89, 95 % CI 1·08, 3·32, P = 0·026). FI is highly prevalent among people with SMI receiving LAI antipsychotic medications. Food-insecure people with SMI engage in less healthy lifestyle behaviours, increasing the risk of future non-communicable disease.

接受长效注射抗精神病药物治疗的严重精神疾病社区个体的粮食不安全患病率及其相关性

患有严重精神疾病 (SMI) 的人有许多可能使他们易患粮食不安全 (FI) 的风险因素；然而，在该人群中，FI 的流行及其对健康的影响尚未得到充分研究。本研究旨在描述 SMI 患者 FI 的患病率及其与生活方式因素的关系。这项横断面研究从澳大利亚悉尼的三个地点的社区服务中招募了接受长效注射 (LAI) 抗精神病药物治疗的 SMI 患者。完成了对身体健康和生活方式因素的评估。χ2测试，独立样本吨计算测试和二元逻辑回归分析以检查生活方式因素与 FI 之间的关系。总共有 233 人完成了评估：男性 154 人（66%），平均年龄 44·8（sd12·7) 年，大多数 (70%) 被诊断为精神分裂症。FI 出现在 104 名参与者 (45%) 中。患有 FI 的人不太可能食用水果（OR 0·42, 95 % CI 0·24, 0·74,磷= 0·003), 蔬菜 (OR 0·39, 95 % CI 0·22, 0·69,磷= 0·001) 和以蛋白质为基础的食物 (OR 0·45, 95 % CI 0·25, 0·83,磷= 0·011) 至少每天一次，进行中度到剧烈的体力活动（分钟）（OR 0·997, 95 % CI 0·993, 1·000,磷= 0·044)，并且更有可能吸烟 (OR 1·89, 95 % CI 1·08, 3·32,磷= 0·026)。FI 在接受 LAI 抗精神病药物的 SMI 患者中非常普遍。患有 SMI 的食物不安全人群的生活方式不太健康，增加了未来患非传染性疾病的风险。
