Clinical Trial Summary

The goal of this clinical trial is to investigate the effects of an individually tailored lifestyle intervention on symptoms and severity of obstructive sleep apnea (OSA), physical activity (PA) levels and sedentary behavior (SB), as well as health and wellbeing in overweight participants with moderate to severe OSA treated with CPAP. Emphasis of the individually tailored SEMC-intervention (protocol of the Sports Medicine Outpatient Clinic of The Wellbeing Services County of Central Finland) is on increasing the amount of total physical activity. The main questions the trial aims to answer are: - Can individually tailored lifestyle intervention, in combination with CPAP therapy, alleviate the severity or symptoms of OSA in overweight participants with moderate to severe OSA? - Does the addition of an individually tailored lifestyle intervention to CPAP therapy improve the quality of life, increase physical functioning, change body composition, and increase physical activity levels or decrease sedentary behavior of participants diagnosed with moderate to severe OSA? - Can enhanced behavioral support (EBS), when integrated with lifestyle intervention and CPAP therapy, lead to more substantial and enduring changes in participants' levels of physical activity or sedentary behavior? Participants will be randomized to either SEMC-intervention group, combination of SEMC-intervention and EBS, or to a control group. In this study, it is hypothesized that participants receiving SEMC-intervention in combination with CPAP therapy will experience greater alleviation of OSA severity and symptoms, improve their quality of life, body composition and physical functioning, as well as increase physical activity levels and decrease their sedentary behavior compared to the control group. In addition, it is hypothesized that participants receiving SEMC-intervention and EBS in combination with CPAP therapy will increase their physical activity levels, and decrease their sedentary behavior to a greater extent, and these changes will be more sustained compared to merely SEMC-intervention or control group.


Description:

Approximately 400,000 adults in Finland are diagnosed with obstructive sleep apnea (OSA). The prevalence of OSA has dramatically increased during the past years. It is estimated that substantial number of patients remain undiagnosed. Untreated OSA is associated with multiple chronic diseases causing increased morbidity, mortality, and health care costs in the western countries. Approximately 70% of patients with OSA are overweight, which is the most common risk factor of OSA. While CPAP therapy often effectively alleviates symptoms of OSA, it usually does not address the underlying issue, as body weight often remains unchanged or even increases with CPAP therapy, especially among young and women. Additionally, CPAP therapy has limited impact on cardiometabolic risk factors, which commonly accumulate in patients with OSA. Exercise, even without significant weight loss, has been shown to positively impact the severity of OSA and its symptoms, as well as several cardiometabolic risk factors. Not to mention the additional benefits of sustained weight reduction. Previous research has focused on exercise interventions that are similar for all participants. There are only few studies executed in clinical, real-life setting or studies with long-term follow-up periods. This clinical trial aims to investigate whether an individually tailored lifestyle intervention (SEMC-protocol) aimed at increasing physical activity levels will affect the severity or symptoms of OSA, participants' quality of life, their cardiometabolic risk factors, anthropometry, functional capacity, or induce lasting behavioral changes (physical activity and sedentary behavior). This trial also investigates whether enhanced behavioral support (EBS) will lead to more substantial and enduring changes in participants' levels of physical activity and sedentary behavior. The participants (n=300) will be recruited at the respiratory outpatient clinic of central Hospital Nova in Jyväskylä, Finland. Information of the clinical trial will be provided to potential participants when starting CPAP therapy according to standard treatment. The candidates will sign a written consent for a phone call from a researcher providing more information on the study. After the phone call, they will decide whether to sign the final informed consent to participate in the study. Participants are randomly allocated to either SEMC-intervention group, combination of SEMC-intervention and EBS-intervention, or to a control group. Comparisons between the groups are made at 3, 6 and 12months after baseline. Additionally, long-term assessments of the participants' health status are assessed from registry data and via questionnaires at 2-, 3-, and five-year follow-up studies. Ethical approval for this study was obtained from the Ethics Committee of The Wellbeing Services County of Central Finland in August 2023. In the power calculations and sample size determination, based on previous literature it was assumed that the change in apnea-hypopnea-index (AHI) for the intervention group is at least 10/h ± 10, and for the controls it is 5 ± 10 /h. Thus, the sample size should be at least 126 participants (63 in the intervention group and 63 in the control group) when the type I error probability is 0.05 and the type II error probability is 0.2. With this sample size, the power is 0.8 (80%). Assuming a dropout rate of at least 10% for the study, 100 participants will be enrolled in both the intervention and control groups.

Study Design


Intervention

Behavioral:
Individually tailored lifestyle and physical activity intervention
Focus of the SEMC-protocol is on increasing PA gradually towards the national recommendations. Emphasis of counseling is on incidental exercise, endurance, and strength training. Techniques of motivational interviewing are utilized. Baseline; MD+PT counseling, medical clearance, mapping lifestyle & life situation, goal setting, measurements, questionnaires, feedback. weeks 1-6: guided group resistance training 1hr, 1x/week. 5-10-minute warm-up, 9 exercises with weight stack equipment on large muscle groups. 2-3 sets, 12-15 repetitions. Modified individually, e.g. according to musculoskeletal problems. Emphasis on learning the basics and safety aspects. After 6 weeks unsupervised training. 3-month: MD counseling and questionnaires. 6-month: MD+PT counseling, assessing safety of PA, measurements, questionnaires, feedback. 12-month: MD+PT counseling (feedback, ensuring continuity of lifestyle changes; redirecting to municipality/NGO activities), measurements, questionnaires, feedback
Individually tailored lifestyle and physical activity intervention combined with enhanced behavioral support -intervention (EBS)
In addition to the SEMC-protocol, the participants will be contacted 3 times during the first 3 months (live / online as preferred). Themes: Session 1: Motivation and illness perceptions. Exploring CPAP use, PA, and SB. Session 2: Self-regulation (feedback, goal setting, self-monitoring, action planning, problem solving), activating social support, prompts/cues, and preparatory behaviors. (Included BCTs from Michie et al 2013 taxonomy: 3.2, 12.2, 8.3,) Session 3: Assessing progress and agenda setting, self-regulation, maintenance of PA. Measurements and questionnaires as with SEMC-protocol.

Secondary Change in Quality of Life RAND 36-Item Health Survey Measured by RAND-36 questionnaire. The RAND 36 questionnaire is a self-report instrument comprising 36 items designed to evaluate eight dimensions of general health status over the preceding four weeks. Responses to the questionnaire are quantified using a numeric scale ranging from 0 (minimum score) to 100 (maximum score), with higher scores indicating better health outcomes. Subsequently, these scores are expressed as a percentage of the total possible score. Items within each dimension are averaged to derive the respective scale scores. Any unanswered items (missing data) are disregarded in the computation of scale scores. Consequently, the scale scores reflect the average of all answered items within the respective dimension. Assessed at base line, 3 months, 6 months, and 12 months (and 2, 3 and 5 years)
