Abstract

Loneliness is an established risk factor for poor cardiometabolic health. People with psychotic disorders experience high rates of both cardiometabolic disease and loneliness, but how these factors are associated is poorly understood. Thus, using data from the second Australian National Survey of Psychosis we examined whether loneliness is associated with the likelihood of cardiometabolic disorder in psychotic illness. Loneliness was assessed using a single-item measure, with a 4-point scale (not lonely; lonely occasionally; some friends but lonely for company; socially isolated and lonely) whilst cardiometabolic status was assessed in terms of the criteria used to determine metabolic syndrome (elevated waist circumference, elevated triglycerides, reduced high-density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose). Logistic regression was employed to examine whether loneliness was associated with metabolic syndrome status, and its individual components, with and without adjustment for confounding variables. Increased loneliness was associated with an increased risk of metabolic syndrome in people with psychosis (OR 121,95% CI 1.08-1.36, p
