Metabolic Syndrome in Patients with Bipolar Disorder Treated with Atypical Antipsychotics, their First-degree Relatives and Control Group

Abstract

Introduction and objective

Patients with serious mental illness have lower life expectancy and higher prevalence of metabolic syndrome compared to normal population. Although, we have little evidence about their first-degree relatives.

Aims

To compare metabolic syndrome in patients with bipolar disorder treated with atypical antipsychotics, their first degree relatives and healthy subjects in two age groups: under and over 40.

Methods

This cross-sectional study was conducted on 100 patients with bipolar disorder treated with atypical antipsychotics, 50 first degree relatives and 135 healthy subjects. The prevalence of metabolic syndrome was assessed based on National Cholesterol Education Program (NCEP).

Results

Under the age of 40, the prevalence of metabolic syndrome was 15.4% in patients with Bipolar disorder, 17.6% in first degree relatives and 7% in healthy subjects. Systolic blood pressure was significantly higher in bipolar disorder patients (P = 0.004). In those over 40, the prevalence of metabolic syndrome was 31.8% in patients with bipolar disorder, 33.3% in first-degree relatives and 32.8% in healthy subjects. Serum levels of HDL were significantly lower in bipolar disorder patients (P = 0.002).

Conclusion

Patients with bipolar disorder and their first-degree relatives have greater chance for cardiovascular disease due to higher metabolic syndrome. Further investigations are needed for evaluating serious mental illness patients and their relatives.
