Major Depressive Disorder and Cardiovascular Disease Risk in Children and Adolescents

Area of Science:

• Pediatric Psychiatry
• Cardiovascular Health
• Adolescent Medicine

Background:

• Major Depressive Disorder (MDD) in youth is linked to premature cardiovascular disease (CVD).
• Previous studies examined individual CVD risk factors in relation to depression.
• This study uses a composite measure to assess the association between depression and CVD risk in youth with MDD.

Purpose of the Study:

• To examine the association between depression and cardiovascular disease (CVD) risk in children and adolescents diagnosed with Major Depressive Disorder (MDD).
• To utilize a validated composite measure for assessing cardiometabolic risk in youth with MDD.

Main Methods:

• Recruited youth with MDD from an outpatient psychiatry program and healthy controls from community settings.
• Assessed depressive symptoms using the Center for Epidemiological Studies Depression Scale for Children.
• Calculated the Continuous Metabolic Syndrome score, a composite measure of CVD risk factors, for all participants.

Main Results:

• Youth with MDD (n=196) exhibited significantly higher cardiovascular disease risk (mean=0.77) compared to healthy controls (n=81, mean=-0.39; p=.002).
• Both depression diagnosis (β=0.40, p=.004) and depressive symptoms (β=0.15, p=.02) were associated with increased CVD risk, after adjusting for covariates.
• The study included 277 participants, with a mean age of 15.2 years and 73.6% females.

Conclusions:

• Adolescents with MDD demonstrate elevated cardiovascular disease risk compared to healthy peers.
• This highlights an early association between depression and cardiovascular disease in youth.
• Childhood and adolescence are critical periods for implementing preventive interventions for cardiovascular health in youth with depression.
