Abstract

BackgroundObesity is associated with an increased risk of mental illness; however, evidence linking body mass index BMI-a measure of overall obesity, to mental illness is inconsistent. The objective of this study was to examine the association of depressive symptoms with waist circumference or abdominal obesity among overweight and obese U.S. adults.

MethodsA cross-sectional, nationally representative sample from the 2005-2006 National Health and Nutrition Examination Survey was used. We analyzed the data from 2,439 U.S. adults 1,325 men and 1,114 nonpregnant women aged ≥ 20 years who were either overweight or obese with BMI of ≥ 25.0 kg-m. Abdominal obesity was defined as waist circumference of > 102 cm for men and > 88 cm for women. Depressive symptoms defined as having major depressive symptoms or moderate-to-severe depressive symptoms were assessed by the Patient Health Questionnaire-9 diagnostic algorithm. The prevalence and the odds ratios ORs with 95% confidence intervals CIs for having major depressive symptoms and moderate-to-severe depressive symptoms were estimated using logistic regression analysis.

ResultsAfter multivariate adjustment for demographics and lifestyle factors, waist circumference was significantly associated with both major depressive symptoms OR: 1.03, 95% CI: 1.01-1.05 and moderate-to-severe depressive symptoms OR: 1.02, 95% CI: 1.01-1.04, and adults with abdominal obesity were significantly more likely to have major depressive symptoms OR: 2.18, 95% CI: 1.35-3.59 or have moderate-to-severe depressive symptoms OR: 2.56, 95% CI: 1.34-4.90 than those without. These relationships persisted after further adjusting for coexistence of multiple chronic conditions and persisted in participants who were overweight BMI: 25.0-< 30.0 kg-m when stratified analyses were conducted by BMI status.

ConclusionAmong overweight and obese U.S. adults, waist circumference or abdominal obesity was significantly associated with increased likelihoods of having major depressive symptoms or moderate-to-severe depressive symptoms. Thus, mental health status should be monitored and evaluated in adults with abdominal obesity, particularly in those who are overweight.
