摘要：Introduction Engaging individuals, suffering from alcohol use disorder (AUD), in a physical activity can be a challenge, and often it is a limitation of the quality of studies on the topic. The aim of the present study is to investigate differences between participants and non-participants in a randomized controlled trial on the effect of physical exercise as add-on to treatment as usual (TAU) to treatment for alcohol use disorder, thereby identifying potential factors that may predict lack of willingness or ability to consider increasing the level of physical activity. Method The Healthy Lifestyle Study was a randomized controlled trial with three arms, of which two included adding physical activities to treatment for AUD as usual. All patients from an outpatient alcohol treatment clinic were invited to participate in the study. 172 accepted participation, and 384 patients either did not show up for information about the study or declined to participate. All patients in the treatment clinic were assessed by means of European Addiction Severity Index (EuropASI). Results The only predictor of participation in the study was the drinking pattern. Patients, who had been drinking every day for the last 6 months were less likely to participate in the study (OR 0.7 CI 0.4–0.9). Neither somatic nor psychiatric health seemed to impact whether or not the patients participated in the study. Conclusion Non-participants did not differ from participants in this study except in their drinking pattern.
