Modifiable health risk behaviours and attitudes towards behaviour change of clients attending community-based substance use treatment services.

INTRODUCTION AND AIMS
Health risk behaviours, such as smoking, nutrition and physical inactivity, are significant contributors to chronic disease for people with substance use disorders. This study reports the prevalence of these behaviours amongst substance use treatment clients, their attitudes towards modifying such behaviours and the acceptability of receiving support to do so. Client characteristics associated with risk status and interest in modifying behaviours were examined.

DESIGN AND METHODS
A cross-sectional survey was undertaken with clients of 15 community substance use treatment services within in New South Wales, Australia. Data for the study were collected via computer assisted telephone interviews.

RESULTS
Of those contactable and eligible, 386 (71%) clients completed the survey. Clients reported a high prevalence of smoking (80%), insufficient fruit and/or vegetable consumption (89%) and insufficient physical activity (31%). Overall, 51-69% of clients reported considering modifying their health risk behaviours and 88-97% thought it was acceptable to be provided preventive care to address such behaviours. Younger clients were more likely to smoke (18-34 years (odds ratio [OR] = 4.6 [95% confidence interval [CI] = 1.9, 11.3]); 35-54 years (OR = 2.6 [95% CI = 1.2, 5.7])) and be interested in increasing vegetable consumption (18-34 years (OR = 4.4 [95% CI = 1.3, 14.8]); 35-54 years (OR = 8.0 [95% CI = 2.5, 25.4])) than older clients (≥55 years).

DISCUSSION AND CONCLUSIONS
There is a high prevalence of health risk behaviours amongst clients of community substance use treatment services. However, contrary to commonly cited barriers to care provision, clients are interested in modifying their risk behaviours and report that receiving preventive care to address these behaviours is acceptable.
