People with a mental illness experience a disproportionate burden of chronic disease morbidity and mortality; contributed to by a higher prevalence of health risk behaviours that increase the risk of chronic disease development. Amongst this population there is little understanding of multiple risk behaviour co-occurrence and client interest in improving multiple such risks. A cross-sectional survey was undertaken with a random selection of 557 clients of 12 community mental health services in Australia. Participants reported their engagement in health risk behaviours (tobacco smoking, harmful alcohol consumption, inadequate fruit and/or vegetable consumption, and inadequate physical activity), and those deemed 'at risk' reported whether they were seriously considering improving their risk behaviours. Almost all participants engaged in at least one risk behaviour (96.1%), with 78.4% of participants engaging in two or more risk behaviours. Of those with two risks, the most frequently paired behaviours were inadequate fruit and vegetable consumption and inadequate physical activity (39.7%); of those with three risks the most common combination was inadequate fruit and vegetable consumption, tobacco smoking and harmful alcohol consumption (42.5%). Of those at risk for all behaviours, 68.4% were interested in improving multiple behaviours, and 14% were interested in improving all; with these participants being most frequently interested in changing smoking, nutrition, and physical activity (19.3%), followed by all risk behaviours (14.0%). The findings strengthen the evidence that people with a mental illness are interested in improving their health risk behaviours and indicate a need to address the multiple health risks in this population group.
