Risk factors for metabolic and cardiovascular disease in inpatients with severe mental illness

Area of Science:

• Cardiology
• Psychiatry
• Public Health

Background:

• Patients with severe mental illness (SMI) experience a disproportionately high burden of somatic illnesses, particularly cardiovascular disease.
• Understanding the cardiometabolic risk profile in SMI populations is critical for reducing associated morbidity and mortality.

Purpose of the Study:

• To compare the cardiometabolic health of hospitalized patients with SMI to a general population sample.
• To identify specific cardiovascular risk factors prevalent in SMI patients.

Main Methods:

• An observational study utilizing entropy balancing (a propensity score matching technique).
• Comparison between psychiatric inpatients and the general population from National Health and Nutrition Examination Survey (NHANES) datasets.
• Analysis of blood pressure, blood glucose, TG:HDL ratio, total cholesterol, and body mass index using linear regression models.

Main Results:

• Psychiatric inpatients exhibited significantly elevated systolic and diastolic blood pressure, blood glucose, and TG:HDL ratios compared to the general population.
• Unexpectedly, total cholesterol and body mass index were lower in the SMI inpatient sample.
• The observed cardiometabolic profile in SMI patients indicates a heightened risk for mortality related to diabetes and hypertension.

Conclusions:

• Hospitalized patients with severe mental illness present a distinct cardiometabolic risk profile.
• Interventions targeting key cardiometabolic indicators are essential to mitigate long-term mortality in this vulnerable group.
