Exercise Effects on Health Status in Patients With Severe Mental Illness (SMI01)

Effectiveness of a Multicomponent Exercise Program on Health Status and Health-related Quality of Life in Patients With Severe Mental Illness: Study Protocol for a Randomized Controlled Trial.

People with severe mental disorders have a mortality rate 2 to 3 times higher than that of the general population, largely due to the presence of comorbidities, with a predominance of cardiovascular disease. This population has a higher risk of developing metabolic syndrome compared to the healthy population. Several factors are involved. The usual pharmacological treatment in people with severe mental disorder is a risk factor for the development of metabolic syndrome and deterioration of physical condition. This is generally compounded by poor health care, high-calorie diets, a sedentary lifestyle, difficulties in coping with life situations that generate emotional states (anxiety and/or depression) that result in unhealthy lifestyle habits related to food, activity, interpersonal relationships, sleep, consumption habits (tobacco, alcohol and drugs) and other environmental factors. Physical exercise has been proposed as one of the most effective treatments to reverse the negative consequences of low levels of physical activity in this population. However, the mechanism of action of exercise on health status and the optimal "dose" and intensity of exercise to achieve the greatest number of benefits with respect to cardiometabolic health in patients with severe mental disorder are unknown.The study will be carried out at the Mental Health Rehabilitation Unit of Navarra, a center under the Mental Health Management of Osasunbidea, where people between 18 and 65 years of age with a diagnosis of severe mental illness in a situation of clinical stability receive treatment.The sample will be composed of 100 participants from consecutive admissions to the Rehabilitation Unit. The subjects will be randomized into 2 groups; a control group that will receive the usual specialized care and an intervention group, which in addition to receiving the usual rehabilitation treatment, will undergo a 6-week multicomponent physical exercise program performed 2 days per week. The effects of exercise on the inflammatory profile, metabolic parameters, physical condition, cognitive function, vascular function, muscle strength, health-related quality of life, lifestyle habits (diet, activation, sleep, substance use) and mood will be evaluated.

An individualized multicomponent exercise program including resistance, aerobic, balance and flexibility exercises.The duration of the sessions will be 45 minutes, and the duration of the whole program will be 6 weeks, equivalent to 12 sessions.

The intervention protocol consists of a 10-minute warm-up doing joint mobility exercises and adaptation exercises to the core exercises of the training session. The exercises will be performed at low intensity in the warm-up. During the main part of the training session, exercises will be performed on a stationary bike at a higher intensity than in the warm-up and strengthening exercises using weights and body weight exercises such as jumping jacks and squats will also be performed. All movements will be performed at 100% of the maximum speed reached in the propulsive phase (understood as executing the movement as fast as possible according to your muscular and functional capacity). The rests between sets will be between 1 and 2 minutes. At the end of the session, there will be a 5-minute return to calm by stretching.

Any 3 of the 5 features: Waist circumference (> 102 cm men/ > 88 cm women),Elevated triglycerides (> 150 mg/dl), reduced HDL cholesterol (< 40 mg/dl men/ < 50 mg/dl women), elevated blood pressure(> 130 mmHg Systolic blood pressure or > 85 mmHg Diastolic blood pressure), and elevated fasting glucose (> 100 mg/dl) glucose.

Physical activity questionnaire. LOW If not moderate or vigorous. MODERATE: 3 or more days of vigorous-intensity activity of at least 20 minutes per day OR b) 5 or more days of moderate-intensity activity and/or walking of at least 30 minutes per day OR c) 5 or more days of any combination of walking, moderate-intensity or vigorous intensity activities achieving a minimum T=total physical activity of at least 600 Metabolic equivalent of task (MET)-minutes/week. HIGH a) Vigorous-intensity activity on at least 3 days (20min minimum, achieving a minimum Total physical activity of at least 1500 MET-minutes/week or 7 or more days of any combination of walking, moderate-intensity or vigorous-intensity activities achieving a minimum Total physical activity of at least 3000 MET-minutes/week.

Maximal dynamic strength (one-maximum muscle strength) was measured for four exercises (knee extension, leg press, row and bench press) using a Smart Strength machine (eGym GmbH, München, Germany). Results were expressed in kilograms.

Health related quality of life.The EQ-5D-5L essentially consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The worse score is 0 and the best score is 100.

Graded exercise tests will be performed on a bicycle ergometer (Lode B.V., Groningen, The Netherlands) to determine the maximal oxygen uptake (VO2max), measured by ml/kg/min.

Depression. The minimum value is 0 points and the maximum value is 63 points. Higher scores mean a worse outcome.

Positive and negative symptoms. Positive scale (minimum score is 7 and maximum score is 49), negative scale (minimum scale is 7 and maximum score is 49) and general psychopathology scale (minimum score is 16 and maximum score is 112 points). Higher scores means a worse outcome.

Pharmacologic/antipsichotic treatment (i.e., pills consumption) associated with the disorder obtained by the medical history.

Sleep quality.The insomnia subscale ranges from 9 to 45, where a higher scores means increased severity of insomnia.

Health related quality of life.The SQLS-R4 is a self-report measure comprising 33 items from which two domains of quality of life, psychosocial feelings (22 items) and cognition and vitality (11 items) are derived. The items are scored on a 5-point frequency-response Likert scale (''never'', ''rarely'', ''sometimes'', ''often'', ''always''). A total score of both domains can also be calculated and individual domain and total scores are standardized by scoring algorithm to a 0 - 100 scale. Higher SQLS-R4 scores indicate comparatively lower quality of life.

Cognitive function.The MATRICS Consensus Cognitive Battery should be used as the standard battery for all clinical trials of potential cognition-enhancing agents for schizophrenia. The battery should always be administered in its entirety in clinical trials (64 minutes). An overall cognitive composite score consisting of equal weighting of the 7 domain scores is the primary cognitive endpoint for agents believed to enhance cognition broadly. Alternatively, a small subset of domains may be combined as the primary cognitive endpoint for agents believed to enhance cognition selectively (e.g., the learning and memory domains).

Cardio-ankle vascular index (CAVI) will be estimated by brachial-ankle oscillometry using a Vasera 2000 device (Fukuda Denshi, Japan) as marker of vascular stiffness.

Pulse wave velocity (PWV) will be estimated by brachial-ankle oscillometry using a Vasera 2000 device (Fukuda Denshi, Japan).
