Effects of a Lifestyle and Sleep Intervention in Non-exercising Adults

Condition(s) studied

Investigational drug(s) / intervention(s)

Lifestyle intervention (physical activity and diet): The physical activity intervention will be based on validated behavior change theories aimed at the initiation and long-term maintenance of physical activity. Participants will be referred to specialists in Adapted Physical Activity for a 6-month program. Exercise sessions will include aerobic exercise and muscle strengthening exercises. Participants will participate in one supervised sessions per week. They will receive instructions for exercising on their own on the other days in order to reach physical activity guidelines. They will also receive instructions and tips to limit sedentary behavior and increase their physical activity throughout the day. Participants will benefit from an initial consultation with a dietitian and 4 follow-up visits. The follow-up visits will be either group-based or individual, based on participants choice and availabilities. Dietary recommendations will be based on public health guidelines in France aimed at eating a healthy, balanced diet.

Lifestyle (physical activity and diet) and Sleep intervention: Participants will benefit from the physical activity and diet intervention detailed above and the following sleep intervention. Participants will fill out an online sleep diagnostic tool includes validated sleep questionnaires (Pittsburgh Sleep Quality Index, Epworth sleepiness scale, Insomnia Severity Index, Berlin questionnaire, Horne and Ostberg questionnaire). Participants will also log their sleep habits in a 14-day sleep diary. Based on the sleep specialists' review of the results of the questionnaires, sleep diary and analysis of sleep-wake patterns, participants who require further exploration will be referred to a sleep specialist for a consultation and if necessary the appropriate treatment for their sleep disorder. All participants in this group will benefit from an individualized sleep hygiene intervention. They will benefit from a baseline interview and 3 follow-up visits.

Health education intervention: Participants randomized to the control group will benefit from a health education intervention in order to limit deception bias.

Study summary

Background. Cardiovascular diseases (CVDs) are the leading cause of premature mortality and disability accounting for one third of all deaths worldwide with considerable impacts on economics and on quality of life. Recent studies suggest that a lifestyle intervention might have a role in the reduction of CDV risk. Lifestyle intervention programs typically combine physical activity, diet and behavior modification components. Poor sleep health is highly prevalent in the general population and contributes to increased risk of several noncommunicable diseases. However, sleep is rarely addressed in lifestyle intervention programs in primary prevention. Given the high prevalence of poor sleep health in people without a diagnosed sleep disorder, and the associated health consequences, there is a clear need for broad-reaching, effective interventions to improve sleep quality in subclinical populations.

Aims. The main objective of this study is to compare a lifestyle intervention program including a sleep intervention compared to a lifestyle intervention program alone on the health-related quality of life (measured by the EQ-5D-5L) and physical activity levels of non-exercising adults.

Methods. Non-exercising adults (n=201) will be recruited in the community via advertisement or their primary care doctor and then randomized to one of the following 3 groups : lifestyle intervention, lifestyle and sleep intervention or standard care. The lifestyle intervention includes a physical activity component (physical activity initiation visit and 6 months of supervised physical activity, once weekly), a diet component (consultation with a dietician and 3 group sessions). The sleep intervention includes individualized face-to-face sessions aimed at improving and optimizing sleep hygiene.

At baseline and after 6 and 12 months, quality of life, physical activity levels, cardiovascular and metabolic risk factors will be evaluated.

Perspectives. This study should determine whether adding a sleep intervention dimension to a lifestyle intervention program provides significant benefits in terms of quality of life and physical activity levels. Based on this study, the modalities of real-life lifestyle intervention programs could be reconsidered in order to provide optimal primary prevention.

Eligibility

Primary outcome measure(s)

• Steps per day — 6 months after randomization
  Measured using an activity monitor (Actigraph)
• Health-related quality of life — 6 months after randomization
  EuroQol (Europe Quality of Life) EQ-5D-5L questionnaire.The EQ-5D-5L is a brief, multiattribute, generic, health status measure composed of 5 questions with Likert response options (descriptive system). The descriptive system covers 5 dimensions of health (mobility, self-care, usual activities, pain or discomfort, and anxiety or depression) with 5 levels of severity in each dimension (no problems, slight problems, moderate problems, severe problems, and unable to perform or extreme problems). The worst health state is (55555) and the best health state is (11111).
