Trajectories of Change in Obesity and Symptoms of Depression: The CARDIA Study
Key result
Higher baseline depressive symptoms were associated with a faster rate of increase in BMI (for Whites) and waist circumference (for Blacks and Whites) over time compared to fewer symptoms.
Why the study?
Are baseline depressive symptoms associated with a faster rate of increase in BMI and waist circumference over time?
Population
4,643 young adults from the Coronary Artery Risk Development in Young Adults study, including Black and…
Comparison
Higher levels of baseline depressive symptoms vs Fewer symptoms of depression at baseline

Should not yet change practice; hypothesis-generating for depression-obesity links in diverse groups.

Population
4,643 young adults from the Coronary Artery Risk Development in Young Adults (CARDIA) study, including Black and White participants.
I
Intervention
Higher levels of baseline depressive symptoms (assessed with the Center for Epidemiological Studies Depression scale)
C
Comparator
Fewer symptoms of depression at baseline
O
Outcome
Change in body mass index (BMI) and waist circumference over time (from year 5 to year 20)surrogate
Higher baseline depressive symptoms predict a faster increase in BMI and waist circumference over time, suggesting depression may drive cardiovascular risk through progressive obesity.
Cite This Study
Needham et al. (2010) conducted a cohort in Obesity and depression (n=4,643). Higher levels of depressive symptoms vs. Fewer symptoms of depression was evaluated on Change in body mass index (BMI) and waist circumference. Higher baseline depressive symptoms were associated with a faster rate of increase in BMI (for Whites) and waist circumference (for Blacks and Whites) over time compared to fewer symptoms.
