Perceived weight discrimination mediates the prospective relation between obesity and depressive symptoms in U.S. and U.K. adults.

ABSTRACT:

Objective

Obesity has been shown to increase risk of depression. Persons with obesity experience discrimination because of their body weight. Across 3 studies, we tested for the first time whether experiencing (perceived) weight-based discrimination explains why obesity is prospectively associated with increases in depressive symptoms.

Method

Data from 3 studies, including the English Longitudinal Study of Ageing (2008/2009-2012/2013), the Health and Retirement Study (2006/2008-2010/2012), and Midlife in the United States (1995/1996-2004/2005), were used to examine associations between obesity, perceived weight discrimination, and depressive symptoms among 20,286 U.S. and U.K. adults.

Results

Across all 3 studies, Class II and III obesity were reliably associated with increases in depressive symptoms from baseline to follow-up. Perceived weight-based discrimination predicted increases in depressive symptoms over time and mediated the prospective association between obesity and depressive symptoms in all 3 studies. Persons with Class II and III obesity were more likely to report experiencing weight-based discrimination, and this explained approximately 31% of the obesity-related increase in depressive symptoms on average across the 3 studies.

Conclusion

In U.S. and U.K. samples, the prospective association between obesity (defined using body mass index) and increases in depressive symptoms in adulthood may in part be explained by perceived weight discrimination. (PsycINFO Database Record

Project description:Background and objectivesPerceived discrimination is a risk factor for poor mental health. However, most studies measure discrimination at one time point, which does not account for heterogeneity in the cumulative patterning of exposure to discrimination. To address this gap, we examine the association between discrimination trajectories and depressive symptoms among black middle-aged and older adults.Research design and methodsData were analyzed from a subsample of black Health and Retirement Study respondents (2006-2018, N = 2926, older than 50 years). General discrimination and racial discrimination trajectories were constructed based on the Everyday Discrimination Scale using repeated measures latent profile analyses. We examined the extent to which the association between discrimination trajectories are differentially associated with depressive symptoms (8-item Center for Epidemiological Studies-Depression scale) using negative binomial regression models adjusted for potential confounders. Effect modification by age and gender was tested.ResultsIndividuals in the persistently high (incident rate ratio [IRR]: 1.70; 95% confidence interval [CI]: 1.49-1.95) and moderate general discrimination trajectories (IRR: 1.19; 95% CI: 1.06-1.33) were more likely to have elevated depressive symptoms in comparison to those in the persistently low trajectory. This relationship was strongest among older adults aged older than 65 years. Respondents in the persistently high racial discrimination trajectory (IRR: 1.50; 95% CI: 1.29-1.73) had a higher risk of elevated depressive symptoms in comparison to respondents in the persistently low trajectory. Sensitivity analyses indicated that there was an independent association between persistently high racial discrimination trajectory class and elevated depressive symptoms, after adjusting for racial discrimination measured at a single time point.Discussion and implicationsCharacterizing longitudinal patterns of perceived discrimination may facilitate the stratification of mental health risk and vulnerability among black middle-aged and older adults. Trajectories of racial discrimination may inform risk of worse depressive symptoms more accurately than a single assessment of discrimination.

Project description:PurposeTo examine the relationship between experiences of discrimination, institutional responses to seminal race events, and depressive symptoms among Black medical students.MethodThis study collected data from a convenience sample of Black U.S. medical students via an anonymous electronic questionnaire in August 2020 that was distributed through the Student National Medical Association and Organization of Student Representatives listservs and an author's social media accounts. It included questions on demographics, institutional responses to seminal race events, experiences of discrimination, and symptoms of depression. Path models were used to examine the relationship between experiences of discrimination, institutional responses to seminal race events, and depressive symptoms among Black medical students.ResultsOf the 750 students completing the survey, 733 (97.7%) were Black. Experiences of discrimination and a lack of institutional responses to seminal race events were associated with more depressive symptoms (b = 0.19, 95% CI: 0.11, 0.26; P < .001 and b = 0.12, 95% CI: 0.04, 0.20; P = .01). After controlling for gender and clinical diagnosis of depression or anxiety before medical school, there was a relationship between experiences of discrimination and institutional responses to seminal race events such that students who reported more experiences of discrimination were more likely to report that their institution did not respond to seminal race events (b = 0.41, 95% CI: 0.34, 0.48; P < .001). Experiences of discrimination moderated the relationship between institutional responses to seminal race events and depressive symptoms (i.e., the relationship between a lack of institutional responses to seminal race events and depressive symptoms was stronger among students who reported more frequent experiences of discrimination).ConclusionsInstitutions dedicated to supporting Black medical student wellness must be diligent in cultivating a culture intolerant of discrimination and deft in their responses to seminal race events in the larger culture.
