Effects of Concurrent Depressive Symptoms and Perceived Stress on Cardiovascular Risk in Low- and High-Income Participants: Findings From the Reasons for Geographical and Racial Differences in Stroke (REGARDS) Study.

ABSTRACT:

Background

Psychosocial risk for cardiovascular disease (CVD) may be especially deleterious in persons with low socioeconomic status. Most work has focused on psychosocial factors individually, but emerging research suggests that the confluence of psychosocial risk may be particularly harmful. Using data from the Reasons for Geographical and Racial Differences in Stroke (REGARDS) study, we examined associations among depressive symptoms and stress, alone and in combination, and incident CVD and all-cause mortality as a function of socioeconomic status.

Methods and results

At baseline, 22 658 participants without a history of CVD (58.8% female, 41.7% black, mean age 63.9±9.3 years) reported on depressive symptoms, stress, annual household income, and education. Participants were classified into 1 of 3 psychosocial risk groups at baseline: (1) neither depressive symptoms nor stress, (2) either depressive symptoms or stress, or (3) both depressive symptoms and stress. Cox proportional hazards models were used to predict physician-adjudicated incident total CVD events (nonfatal myocardial infarction, nonfatal stroke, and cardiovascular death) and all-cause mortality over a median of 7.0 years (interquartile range 5.4-8.3 years) of follow-up. In fully adjusted models, participants with both depressive symptoms and stress had the greatest elevation in risk of developing total CVD (hazard ratio 1.48, 95% CI 1.21-1.81) and all-cause mortality (hazard ratio 1.33, 95% CI 1.13-1.56) but only for those with low income (<$35 000) and not high (?$35 000) income. This pattern of results was not observed in models stratified by education.

Conclusions

Findings suggest that screening for a combination of elevated depressive symptoms and stress in low-income persons may help identify those at increased risk of incident CVD and mortality.

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:Aims:Relatively little is known about the health outcomes associated with very low plasma concentrations of high-density lipoprotein cholesterol (HDL-C) mainly because of the small numbers of individuals with such extreme values included in clinical trials. We, therefore, investigated the association between low and very low HDL-C concentration at baseline and incident all-cause-mortality, death from malignant disease (i.e. cancer), and with fatal or non-fatal incident coronary heart disease (CHD) in individuals from the Reasons for Geographical And Racial Differences in Stroke (REGARDS) study. Methods and results:Analysis was based on 21 751 participants from the REGARDS study who were free of CHD, other cardiovascular disease, and cancer at baseline and were categorized by baseline HDL-C into <30?mg/dL (very low), 30-<40?mg/dL (low), and ?40?mg/dL (reference). A series of incremental Cox proportional hazards models were employed to assess the association between the HDL-C categories and outcomes. Statistical analysis was performed using both complete case methods and multiple imputations with chained equations. After adjustment for age, race, and sex, the hazard ratios (HRs) comparing the lowest and highest HDL-C categories were 1.48 [95% confidence interval (CI) 1.28-1.73] for all-cause mortality, 1.35 (95% CI 1.03-1.77) for cancer-specific mortality and 1.39 (95% CI 0.99-1.96) for incident CHD. These associations became non-significant in models adjusting for demographics, cardiovascular risk factors, and treatment for dyslipidaemia. We found evidence for an HDL paradox, whereby low HDL (30-<40?mg/dL) was associated with reduced risk of incident CHD in black participants in a fully adjusted complete case model (HR 0.63; 95% CI 0.46-0.88) and after multiple imputation analyses (HR 0.76; 95% CI 0.58-0.98). HDL-C (<30?mg/dL) was significantly associated with poorer outcomes in women for all outcomes, especially with respect to cancer mortality (HR 2.31; 95% CI 1.28-4.16) in a fully adjusted complete case model, replicated using multiple imputation (HR 1.81; 95% CI 1.03-3.20). Conclusion:Low HDL-C was associated with reduced risk of incident CHD in black participants suggesting a potential HDL paradox for incident CHD. Very low HDL-C in women was significantly associated with cancer mortality in a fully adjusted complete case model.

Project description:OBJECTIVE:To 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. METHODS:Participants 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). RESULTS:The 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. CONCLUSIONS:Elevated 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.
