Health Assessment in People With Severe Mental Illness (PHASMI)
Health Assessment in People With Severe Mental Illness: The PHASMI Study
People living with severe mental illness (SMI) experience substantial physical health inequalities, including an increased prevalence of cardiovascular disease, obesity, metabolic disorders, reduced physical fitness, and premature mortality. Physical inactivity, prolonged sedentary behavior, sleep disturbances, and the metabolic effects of psychiatric medications may contribute to these health problems.
The PHASMI study aims to provide a comprehensive assessment of physical health, cardiorespiratory fitness, cardiometabolic risk, physical functioning, lifestyle characteristics, emotional well-being, and health-related quality of life in adults with severe mental illness.
The primary objective is to investigate associations between sociodemographic, clinical, and lifestyle characteristics and cardiorespiratory fitness, assessed through peak oxygen uptake (VO2peak).
PHASMI is an observational, descriptive, cross-sectional study conducted in Álava, Spain. The anticipated sample comprises 275 adults aged 18 to 65 years with a diagnosis of severe mental illness according to DSM-5 criteria established by psychiatry specialists. Participants will be recruited through the Mental Health Network of Álava, including individuals receiving community-based psychiatric care and hospitalized patients.
Participants will undergo a comprehensive health assessment involving cardiopulmonary exercise testing on a treadmill using a modified Bruce protocol, the Modified Shuttle Walk Test, anthropometric measurements, body composition analysis, blood pressure measurements, electrocardiography, laboratory analyses, handgrip strength testing, and standardized assessments of physical functioning.
Physical activity, sedentary behavior, and sleep will be assessed using standardized questionnaires and a wrist-worn ActiGraph GT3X+ accelerometer over eight consecutive days. Emotional well-being and health-related quality of life will be evaluated using validated questionnaires.
The main in-person assessments will be conducted over two consecutive days at the University of the Basque Country and the Psychiatric Hospital of Álava. Written informed consent will be obtained before participation.
No experimental treatment or therapeutic intervention will be assigned. By examining associations between physical fitness, cardiometabolic health, lifestyle characteristics, and psychological well-being, PHASMI seeks to identify potentially modifiable factors associated with poorer physical health and inform future prevention and health promotion strategies for people living with severe mental illness.

BACKGROUND AND SCIENTIFIC RATIONALE
Severe mental illness (SMI) is associated with substantial inequalities in physical health, increased morbidity, and premature mortality compared with the general population. Individuals living with SMI experience a higher prevalence of cardiovascular disease, metabolic disorders, obesity, diabetes mellitus, and other chronic noncommunicable diseases.
Several interconnected factors contribute to these health inequalities, including insufficient physical activity, prolonged sedentary behavior, smoking, socioeconomic disadvantage, psychiatric symptoms, and the metabolic effects of psychotropic medications.
Despite growing recognition of the importance of physical health in psychiatric populations, systematic and comprehensive physical health assessments remain insufficiently integrated into routine mental healthcare.
The PHASMI study has been designed to provide a multidimensional characterization of physical health, cardiometabolic risk, cardiorespiratory fitness, physical functioning, lifestyle characteristics, emotional well-being, and quality of life among adults with severe mental illness.
The study combines objective physiological measurements, laboratory analyses, standardized physical performance tests, wearable activity monitoring, clinical information, and validated questionnaires.

CARDIORESPIRATORY FITNESS AND CARDIOVASCULAR HEALTH
Cardiorespiratory fitness (CRF) reflects the integrated capacity of the cardiovascular, respiratory, and muscular systems to transport and utilize oxygen during sustained physical activity. CRF is an important indicator of overall health and a predictor of cardiovascular morbidity and mortality.
Individuals with severe mental illness frequently demonstrate lower levels of cardiorespiratory fitness than the general population. Reduced fitness may be associated with physical inactivity, sedentary behavior, obesity, psychiatric symptoms, medication-related adverse effects, and limited opportunities to engage in regular physical activity.
Cardiopulmonary exercise testing (CPET) allows direct assessment of aerobic capacity through respiratory gas exchange measurements during progressively increasing exercise intensity. However, CPET requires specialized equipment and trained personnel, potentially limiting its routine implementation in mental healthcare settings.
Field-based assessments, such as the Modified Shuttle Walk Test (MSWT), offer a potentially more accessible approach to evaluating functional exercise capacity.
The PHASMI protocol includes both CPET and MSWT to characterize cardiorespiratory fitness and functional exercise capacity in adults with severe mental illness.
-
CARDIOMETABOLIC HEALTH AND SYSTEMIC INFLAMMATION
People with severe mental illness have an increased prevalence of cardiovascular risk factors, including hypertension, dyslipidemia, insulin resistance, diabetes mellitus, obesity, and metabolic syndrome.
Alterations in body composition, particularly increased adiposity and reduced skeletal muscle mass, may contribute to metabolic dysfunction and cardiovascular risk.
Low-grade systemic inflammation has also been proposed as a potential mechanism linking severe mental illness with chronic physical health conditions.
PHASMI will evaluate anthropometric characteristics, body composition, blood pressure, biochemical markers, metabolic indicators, and inflammatory parameters.
Cardiovascular risk will be estimated using established prediction tools, including SCORE2, the Framingham risk model, and PRIMROSE, according to their respective applicability criteria.
-
PHYSICAL ACTIVITY, SEDENTARY BEHAVIOR, AND SLEEP
Physical inactivity and prolonged sedentary behavior are common among people with severe mental illness and may contribute to reduced cardiorespiratory fitness, increased adiposity, cardiometabolic dysfunction, and poorer quality of life.
Sleep disturbances are also frequently reported in psychiatric populations and may interact with cardiovascular health, metabolic regulation, emotional well-being, and daily functioning.
PHASMI will combine objective accelerometry with self-reported questionnaires to characterize physical activity, sedentary behavior, and sleep.
This approach will provide complementary information regarding habitual activity patterns, sleep duration, sleep efficiency, and sedentary time.
-
MUSCLE STRENGTH, PHYSICAL FUNCTIONING, AND QUALITY OF LIFE
Muscle strength and physical functioning are important components of overall health and functional independence.
Reduced muscle strength and impaired physical performance may contribute to limitations in daily activities and increased vulnerability to chronic disease.
PHASMI will assess muscle strength, functional mobility, and physical performance using standardized tests.
Emotional well-being and health-related quality of life will also be assessed through validated questionnaires.
The integration of physical, psychological, and lifestyle-related variables will allow a comprehensive characterization of the health of adults with severe mental illness.
-
STUDY HYPOTHESIS
The primary hypothesis is that sociodemographic, clinical, and lifestyle characteristics are associated with cardiorespiratory fitness among adults with severe mental illness.
