Depressive symptoms do not discriminate: racial and economic influences between time-varying depressive symptoms and mortality among REGARDS participants.

ABSTRACT:

Purpose

Depressive symptoms relapse and remit over time, perhaps differentially by race and income. Few studies have examined whether time-varying depressive symptoms (TVDS) differentially predict mortality. We sought to determine whether race (white/black) and income (MethodsThe REGARDS study is a prospective cohort study among community-dwelling U.S. adults aged 45 years or older. Cox proportional hazard models were constructed to separately analyze the association between mortality (all cause, cardiovascular death, noncardiovascular death, and cancer death) and TVDS in race and income stratified models.

Results

Point estimates were similar and statistically significant for white (aHR = 1.24 [95% CI: 1.10, 1.41]), black (aHR = 1.26 [95% CI: 1.11, 1.42]), and low-income participants (aHR = 1.28 [95% CI: 1.16, 1.43]) for the association between TVDS and mortality. High-income participants had a lower hazard (aHR = 1.19 [95% CI: 1.02, 1.38]). Baseline depressive symptoms predicted mortality in blacks only (aHR = 1.17, 95% CI: [1.00, 1.35]).

Conclusions

We found that TVDS significantly increased the immediate hazard of mortality similarly across race and income strata. TVDS may provide more robust evaluations of depression impact compared with the baseline measures, making apparent racial disparities cited in the extant literature a reflection of the imperfection of using baseline measures.

We sought to determine whether race (white/black) and income (</≥$35,000) moderate the association between TVDS and mortality in a large cohort.<h4>Methods</h4>The REGARDS study is a prospective cohort study among community-dwelling U.S. adults aged 45 years or older.

Project description:ObjectiveTo describe the relationship between metabolic health parameters and depressive symptoms and perceived stress, and whether the co-occurrence of these two psychological stressors has an additive influence on metabolic dysregulation in adults at different levels of body mass index (BMI) without diabetes.MethodsParticipants without diabetes (N = 20,312) from the population-based REasons for Geographic And Racial Differences in Stroke (REGARDS) study (recruited between 2003-2007) who had a body mass index (BMI) ≥ 18.5 kg/m2 were included in this cross-sectional analysis. Mean age of sample was 64.4 years, with 36% African American, and 56% women. Depressive symptoms and perceived stress were measured using brief versions of the Center for Epidemiologic Studies Depression (CES-D-4 item) questionnaire and Cohen Perceived Stress Scale (PSS), respectively. Metabolic health parameters included waist circumference, blood pressure (systolic and diastolic), low- and high-density lipoprotein (LDL, HDL) cholesterol, triglycerides, fasting glucose, and high sensitivity C-reactive protein (hs-CRP). Sequentially adjusted general linear regression models (GLM) for each metabolic parameter were used to assess the association between having both elevated depressive symptoms and stress, either of these psychological risk factors, or none with all analyses stratified by BMI category (i.e., normal, overweight, and obesity).ResultsThe presence of elevated depressive symptoms and/or perceived stress was generally associated with increased waist circumference, higher CRP, and lower HDL. The combination of depressive symptoms and perceived stress, compared to either alone, was typically associated with poorer metabolic health outcomes. However, sociodemographic and lifestyle factors generally attenuated the associations between psychological factors and metabolic parameters.ConclusionsElevated depressive symptoms in conjunction with high levels of perceived stress were more strongly associated with several parameters of metabolic health than only one of these psychological constructs in a large, diverse cohort of adults. Findings suggest that healthy lifestyle factors may attenuate the association between psychological distress and metabolic health impairment.

Project description:Albuminuria is an important risk factor for progressive chronic kidney disease (CKD) and is more prevalent in black than white adults. We sought to determine the association between low income and albuminuria and whether this association differs for blacks and whites.Cross-sectional study.9,144 black and 13,684 white US adults 45 years and older in the population-based Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study.Self-reported annual household income category (?$75,000, $35,000-$74,999, $20,000-$34,999, and <$20,000); black and white race.Albuminuria defined as high (30-300 mg/g) or very high (>300 mg/g) urinary albumin-creatinine ratio (ACR). Multinomial logistic regression used to examine the race-stratified association between categories of income and albuminuria (normal, high, or very high ACR).Overall, geometric mean ACR was 10.2 mg/g and was higher for blacks (11.8 mg/g) than whites (9.3 mg/g), P<0.001. Lower income was associated with a higher prevalence of albuminuria for both whites and blacks in unadjusted analyses. After adjustment for demographics, lifestyle factors, comorbid illnesses, and estimated glomerular filtration rate, there was a trend toward a stronger association between lower income levels and high ACR in blacks (ORs of 1.38 [95% CI, 1.07-1.77], 1.36 [95% CI, 1.05-1.75], and 1.58 [95% CI, 1.21-2.05] for income levels of $35,000-$74,999, $20,000-$34,999, and <$20,000, respectively; reference group is those with income?$75,000) compared with whites (ORs of 0.95 [95% CI, 0.81-1.12], 0.95 [95% CI, 0.79-1.14], and 1.26 [95% CI, 1.02-1.55], respectively); P interaction=0.08 between race and income. Results were similar for very high ACR and subgroups of participants with diabetes or hypertension.Cross-sectional design; not all REGARDS participants provided their annual income.Lower income may be associated more strongly with albuminuria in blacks than whites and may be a determinant of racial disparities in albuminuria.

Project description:ImportanceDepression is a common mental health disorder in the US. Depressive symptoms have been associated with increased cardiovascular disease incidence and mortality, but studies have largely focused on narrow population subgroups.ObjectiveTo examine the association between depressive symptoms and mortality in a large, diverse, nationally representative sample of US adults, and to examine how lifestyle factors mediate this association.Design, setting, and participantsThis was a prospective cohort study of a nationally representative sample of US adults using National Health and Nutrition Examination Survey 2005 to 2018 data linked with the National Death Index through 2019 for adults aged 20 years and older. Data were analyzed between March 1 and May 26, 2023.Main outcomes and measuresAll-cause, cardiovascular disease, and ischemic heart disease mortality. Depressive symptoms were defined by Patient Health Questionnaire-9 scores and were categorized as none or minimal, mild, and moderate to severe. Secondarily, we assessed degree of mediation by lifestyle factors.ResultsA total of 23 694 participants were included (unweighted n = 11 862 male [weighted 49.8%]; mean [SE] age, 44.7 [0.24] years). Prevalences of mild and moderate to severe depression were 14.9% and 7.2%, respectively. For all-cause mortality, hazard ratios were 1.35 (95% CI, 1.07-1.72) for mild depressive symptoms vs none and 1.62 (95% CI, 1.24-2.12) for moderate to severe depressive symptoms vs none. The corresponding hazard ratios were 1.49 (95% CI, 1.11-2.00) and 1.79 (95% CI, 1.22-2.62) for cardiovascular disease mortality and 0.96 (95% CI, 0.58-1.60) and 2.21 (95% CI, 1.24-3.91) for ischemic heart disease mortality. The associations were largely consistent across subgroups. Approximately 11.0% to 16.1% of the associations between depression and mortality could be explained by lifestyle factors. Feeling tired or having little energy, poor appetite or overeating, and having little interest in doing things were independently associated with all-cause and cardiovascular disease mortality but not with ischemic heart disease mortality.Conclusions and relevanceIn this prospective cohort study of a nationally representative sample of US adults, there was a graded positive association between depressive symptoms and mortality. Public health efforts to improve awareness and treatment of depression and associated risk factors could support a comprehensive, nationwide strategy to reduce the burden of depression.
