Abstract
This study aims to evaluate the effects on physical activity PA and eating behavior EB of a tailored behavioral medicine intervention and firsttime continuous positive airway pressure CPAP treatment compared with firsttime CPAP treatment and advice in patients with obstructive sleep apnea syndrome OSAS and overweightSeventythree patients mean ± SD 55 ± 12 years with overweight body mass index BMI 345 ± 48 and moderate or severe OSAS ApneaHypopnea Index 417 ± 209 scheduled for CPAP prescription were randomized to a control group CPAP and advice on the association between weight and OSAS or an experimental group CPAP and a 6month behavioral medicine intervention targeting PA and EB At baseline and after 6 months eating behavior food frequency screening and Dutch Eating Behavior Questionnaire weight BMI and waist circumference were assessed at one point while PA and sedentary time were measured with accelerometry during 4 daysThe experimental group reduced 21 kg ±46 in weight and 3 cm ±49 in waist circumference significantly more than the control group At 6 months the experimental group ate more fruit and fish/shellfish than the control group Low and moderate to vigorous PA did not change over time either within or between groups Regarding BMI steps and sedentary time there were withingroup differences but no differences between groupsThe behavioral medicine intervention did not change physical activity but facilitated changes in EB in patients with OSAS and overweight The amount of weight loss and reduction in waist circumference favored the participants receiving this treatment Since the strategies for achieving behavioral changes were tailored according to the individual’s goals and personal functional behavioral analyses and progressed slowly in a graded manner it might require higher PA quotas or a period longer than 6 months to reveal a behavioral change of larger proportionsThe study was financially supported by the Swedish Research Council Stockholm Sweden Caring Sciences Funding at the Faculty of Medicine Uppsala University Uppsala Sweden Uppsala County Council Uppsala Sweden the Swedish Heart and Lung Association Stockholm Sweden Swedish Sleep Research Umeå Sweden and the Association against Heart and Lung Diseases Uppsala Sweden The authors thank Gunilla Hägg RN for excellent assistance with data collection
