Depression, Inflammation, and the Moderating Role of Metformin: Results From the Midlife in the United States Study and Sacramento Area Latino Study on Aging.
Objective: Depression can promote inflammation and accelerate aging. Metformin, a widely prescribed antidiabetic, has shown promising preclinical evidence of aging-related health benefits, including decreased inflammation. The current study examined whether metformin usage buffers the association between depressive symptoms and inflammatory markers in two large samples of middle-aged and older, primarily White adults, and older Latino adults.
Methods: Data from the Midlife in the United States Study ( N = 1255) and the Sacramento Area Latino Study on Aging ( N = 1786) included information on medication use, depressive symptoms, and inflammatory markers, namely, interleukin 6 (IL-6), tumor necrosis factor α, and C-reactive protein (CRP). These data were merged into a harmonized sample, and the sample group variable was included in a three-way interaction for analysis.
Results: Specifically, in the Midlife in the United States Study sample, metformin buffered the association between depressive symptoms and CRP ( b = -0.029, standard error [SE] = 0.013, p = .007) and IL-6 ( b = 0.21, SE = 0.010, p = .046), whereas no significant association was found with tumor necrosis factor α. Metformin nonusers displayed higher depressive symptoms associated with elevated CRP ( b = 0.01, SE = 0.003, p < .001) and IL-6 ( b = 0.011, SE = 0.003, p < .001), whereas this association was not present among metformin users ( p values > .068). Conversely, in the Sacramento Area Latino Study on Aging sample, metformin use did not show a significant protective link.
Conclusions: Results from mostly White, highly educated adults supported a mitigating role of metformin in ties between depression, a well-known behavioral risk factor, and inflammation, a key source of biological aging. However, the benefits did not extend to a large sample of older Mexican Americans. The findings reveal a hidden potential benefit of this therapeutic agent and raise important questions around its health equity.
Trial registration: The study was preregistered on OSF ( https://osf.io/c92vw/ ).
期刊介绍:
Psychosomatic Medicine is the official peer-reviewed journal of the American Psychosomatic Society. The journal publishes experimental, clinical, and epidemiological studies on the role of psychological and social factors in the biological and behavioral processes relevant to health and disease. Psychosomatic Medicine is an interdisciplinary peer-reviewed journal devoted to high-quality science on biobehavioral mechanisms, brain-behavior interactions relevant to physical and mental disorders, as well as interventions in clinical and public health settings.
Psychosomatic Medicine was founded in 1939 and publishes interdisciplinary research articles relevant to medicine, psychiatry, psychology, and other health-related disciplines. The print journal is published nine times a year; most articles are published online ahead of print. Supplementary issues may contain reports of conferences at which original research was presented in areas relevant to the psychosomatic and behavioral medicine.
