Researchers analyzed the metabolic indexes of patients with common mental disorders in a stable stage with the aim to explore the related factors of obesity among them.

• Included were 576 individuals with major depressive disorder (MDD), bipolar disorder (BD) or schizophrenia (SCZ).

• Relative to patients with MDD, those with BD and SCZ are more prone to obesity.

• In multiple linear regression analysis, increase in the value of BMI was observed with the increase of age, TG, LDL, LDH, SCr, UA, HbA1c and hsCRP.

• Decrease in BMI was observed in correlation with an increase in HDL.

• Based on findings, researchers recommend regularly checking blood indicators and strengthening weight management in people with mental disorders to lower the risk of obesity and promote their health.
