Obesity and synergistic risk factors for chronic kidney disease in African American adults: the Jackson Heart Study

Abstract Background Individuals with chronic kidney disease (CKD), hypertension (HTN), or diabetes mellitus (DM) are at increased risk for cardiovascular disease (CVD). The extent to which psychosocial factors are associated with increased CVD risk within these individuals is unclear. Black individuals experience a high degree of psychosocial stressors due to socioeconomic factors, environment, racism, and discrimination. We examined the association between psychosocial factors and risk of CVD events among Black men and women with CKD and CKD risk factors in the Jackson Heart Study. Methods and Results We identified 1919 participants with prevalent CKD or CKD risk factors at baseline. We used rotated principal component analysis - a form of unsupervised machine learning that may identify constructs not intuitively identified by a person - to describe five groups of psychosocial components (including negative moods, religiosity, discrimination, negative outlooks, and negative coping resources) based on a battery of questionnaires. Multiple imputation by chained equation (MICE) was used to impute missing covariate data. Cox models were used to quantify the association between psychosocial components and incident CVD, defined as a fatal coronary heart disease event, myocardial infarction, cardiac procedure (angiography or revascularization procedure), or stroke. Of the 929 participants in the analysis, 67% were female, 28% were current/former smokers with mean age of 56 years and mean BMI of 33 kg/m2. Over a median follow-up of 8 years, 6% had an incident CVD event. In multivariable models, each standard deviation (SD) increase in the religiosity component was associated with an increased hazard for CVD event (hazard ratio [HR] = 1.52, 95% CI: 1.09–2.13). Conclusions Religiosity was associated with CVD among participants with prevalent CKD or CKD risk factors. Studies to better understand the mechanisms of this relationship are needed.

Increased Risk

Background: Chronic Kidney Disease (CKD) is an important public health issue and is associated with an increased risk of cardiovascular disease. Risk factors for CKD are well established, but most are typically assessed at or near the time of CKD diagnosis. Our hypothesis was that risk factors for CKD are present earlier in the course of the disease. We compared the prevalence of risk factors between CKD cases and controls at time points up to 30 years prior to CKD diagnosis. Methods: Participants were drawn from the Framingham Heart Study Offspring cohort. CKD was defined as an estimated glomerular filtration rate of ≤60ml/min/1.73m2. Incident CKD cases occurring at examination cycles 6, 7, and 8 were age- and sex-matched 1:2 to controls. Risk factors including systolic blood pressure (SBP), hypertension, lipids, diabetes, smoking status, body mass index (BMI) and dipstick proteinuria were measured at the time of CKD diagnosis and 10, 20 and 30 years prior. Logistic regression models, adjusted for age, sex, and time period, were constructed to compare risk factor profiles at each time point between cases and controls Results: During follow-up, 441 new cases of CKD were identified and these were matched to 882 controls (mean age 69.2 years, 52.4% women). Up to 30 years prior to CKD diagnosis, those who ultimately developed CKD were more likely to have hypertension (OR 1.74, CI 1.21-2.49), be obese (OR 1.74, CI 1.15-2.63) and have higher triglycerides (OR 1.43, CI 1.12-1.84, p=0.005 per 1 standard deviation increase). Each 10mmHg increase in SBP was associated with an OR of 1.22 for future CKD (95% CI 1.10-1.35) Additionally, cases were more likely to have diabetes (OR 2.90, CI 1.59-5.29) and be on antihypertensive therapy (OR 1.65, CI 1.14-2.40, p=0.009) up to 20 years prior to diagnosis. Increasing HDLc was associated with a lower risk of CKD (OR 0.84, CI 0.81-0.97 per 10mg/dl). Conclusions: As many as 30 years prior to diagnosis, risk factors for CKD are identifiable. In particular, modifiable risk factors such as obesity, hypertension and dyslipidemia are present early in the course of the disease. These findings demonstrate the importance of early identification of risk factors in patients at risk of CKD through a life-course approach.

Age And Sex

Background: The presence of chronic kidney disease is greater in African Americans than in non-Hispanic whites. Though there is data to show a relation between endothelial dysfunction and end-stage kidney disease, the relation to mild and moderate chronic kidney disease (particularly in African Americans) is unclear. Methods and Results: Digital arterial tonometry was performed during Exam 2 and 3 of the Jackson Heart Study using the endoPAT2000. Data from digital arterial tonometry included baseline pulse wave amplitude (BPA) as a measure of endothelial tone and reactive hyperemic index (F-RHI) as a measure of endothelial function. For this study, the estimated glomerular filtration rate (eGFR) was calculated using the MDRD equation. Those participants with eGFR < 60 ml/min/1.73m2 were defined as having CKD. Participants with eGFR < 15 ml/min/1.73m2 were excluded from the analysis. Microalbuminuria in this study was defined as a urinary albumin:creatinine ratio ≥ 17mg/g in men and ≥ 25 mg/g in women. We compared the differences in least square means adjusted for age and sex, and adjusted for multiple traditional clinical covariates using a generalized linear model. Results: There were 834 participants in the study population (mean age 58.5 years, 61% women); 87 (10.4%) participants with CKD and 108 (13.0%) with microalbuminuria. In age and sex adjusted samples, we found that both BPA and F-RHI were significantly associated with CKD in the pooled samples. However in multivariable adjusted analysis the relation was no longer significant in either the pooled or sex-specific samples. In the multivariable adusted analysis,BPA was significantly (P=0.036) associated with microalbuminuria in men and F-RHI was weakly significantly (P=0.08) associated with microalbuminuria in women. Conclusion: We found that endothelial dysfunction as measured by digital arterial tonometry is not significantly associated with chronic kidney disease. There is an association of endothelial tone in men and endothelial dysfunction in women with microalbuminuria.

Management Behaviors

Patients living with chronic kidney disease (CKD) must balance the medical management of their kidney disease and other chronic conditions with their daily lives, including managing the emotional and psychosocial consequences of living with a chronic disease. Self-management is critical to managing chronic kidney disease, as treatment consists of a complex regimen of medications, dosages, and treatments. This is a particularly important issue for older African American adults who will comprise a significant portion of the older adult population in the coming years. Yet current conceptualizations of self-management behaviors cannot adequately address the needs of this population. Embodiment theory provides a novel perspective that considers how social factors and experiences are embodied within decision-making processes regarding self-management care among older African Americans. This paper will explore how embodiment theory can aid in shifting the conceptualization of self-management from a model of individual choice, to a framework that cannot separate lived experiences of social, political, and racial factors from clinical understandings of self-management behaviors. This shift in the conceptualization of self-management is particularly important to consider for CKD management because the profound illness burdens require significant self-management and care coordination skills.
