Trends in obesity prevalence among adults with depression in the United States, 2005 to 2023

TRENDS IN OBESITY PREVALENCE AMONG ADULTS WITH DEPRESSION IN THE UNITED STATES, 2005 TO 2023

The age-standardized prevalence of obesity among US adults with depression rose from 42.8% in 2005–2008 to 46.3% in 2021–2023, with increases particularly pronounced in the more severe obesity classes and among women.

The study aimed to clarify the long-term trend in obesity prevalence among individuals with depression, an issue that remains unclear despite the known frequent co-occurrence of depression and obesity and their mutually adverse effects on prognosis. Data were obtained from the 2005–2023 cycles of the National Health and Nutrition Examination Survey (NHANES). From an initial pool of 88,429 people invited to participate, the sample was narrowed to 51,221 individuals aged 20 years or older, then to 50,440 nonpregnant individuals, 4,114 individuals with PHQ-9 scores of 10 or higher, and finally 4,035 individuals with available height and weight data, of whom 1,970 had obesity. Obesity was defined as a body mass index of 30 kg/m2 or higher and categorized as Class I (30–34.9), Class II (35–39.9), and Class III (40 or higher); trends were evaluated using a trend test. The age-standardized prevalence of obesity among adults with depression rose from 42.8% in 2005–2008 to 46.3% in 2021–2023 (P for trend <0.001). By sex, prevalence increased from 44.0% to 52.1% among women, while declining from 40.6% to 37.2% among men. In terms of severity, Class I obesity decreased slightly (from 21.0% to 19.0%), whereas Class II obesity increased significantly from 11.5% to 15.8% (P<0.001), and Class III obesity increased significantly from 10.3% to 11.4% (P<0.001). The authors state that the increases in both the prevalence and severity of obesity among adults with depression constitute a combined public health challenge, and that weight management and routine metabolic monitoring should become core components of standard psychiatric care.
