NCT06743711

Brief Summary

This project aims to evaluate feasibility, validity and clinically applicability to systematically measure fitness in patients with severe mental illness. The research project is a validation study using a cross-sectional design. The project will include 50 people with severe mental illness and 25 healthy controls without present or previous mental illness. The protocol includes a baseline visit where three different ways of measure fitness will be carried out, and a 14-day period of physical activity monitoring.

Outcome Measures

Primary Outcomes (1)

  • Estimated VO2max

    The revised Ekblom-Bak submaximal cycle-ergometer fitness test (EBsub) will be carried out to estimate VO2max and validated against measured VO2max during a cardiopulmonary exercise test (CPET) including calculation of coefficient variation, limits of agreement, mean absolute percentage error, linear regression analyses for obtaining R-squared values and standard errors of the estimate, and Bland-Altman plotting. VO2max will be assessed during an incremental cycle protocol until exhaustion conforming to the state-of-the-art CPET. Oxygen consumption and carbon dioxide excretion rates will be measured using a "breath-by-breath" analysing system coupled to a fitted silicone mask, strapped around the participants head, covering nose and mouth (Vyntus CPX, Jaeger). VO2max will be defined as the average of the three highest oxygen consumption measurements. VO2max will be estimated with the EBsub conforming to the developing authors guidelines.

Study Arms (2)

Patients

Adults with severe mental illness in treatment with antipsychotic medications

Healthy controls

Adults without present or previous mental illness, and no first-degree relatives with present or previous mental illness, matched to the patient group for gender, age, and BMI.

Eligibility Criteria

Age18 Years - 45 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Patients will be recruited from inpatient and outpatient clinics in the Capital Region of Denmark. Furthermore, recruitment will also be carried out through two ongoing randomized controlled trials i) Value of gym-based exercise training for young adults with severe mental illness: A pragmatic, single-blinded, multicenter randomized controlled trial - the Vega trial (NCT05461885), and ii) Effectiveness of a pragmatic, metabolic care clinic for patients with severe mental illness (NCT06624462). Healthy controls will be recruited through announcements in the Capital Region of Denmark, through the webpages www.forsøgsperson.dk and www.forskningnu.dk and social media.

You may qualify if:

  • years
  • Diagnosis within schizophrenia spectrum or affective disorders (i.e. F2.x or F3.x according to ICD-10 classification)
  • current antipsychotic treatment for more than one month on a regular daily dose
  • Able to give informed consent.

You may not qualify if:

  • Clinical or laboratory evidence of uncompensated medical disease
  • Unstable psychiatric disorder
  • Acute suicidal risk
  • Planned hospitalization within the study period.
