Abstract
Introduction:
Evidence suggests individuals with a history of adverse childhood experiences have higher odds of developing kidney disease versus individuals with no adverse childhood experiences. However, no study has examined the influence of coexisting adverse childhood experiences and kidney disease on mortality risk. This study uses a longitudinal survey of adults to examine the influence of coexisting adverse childhood experiences and decreased renal function on all-cause mortality in a sample of U.S. adults.
Methods:
A total of 1,205 adults participating in the Midlife Development in the United States series between 1995 and 2014 were used for this analysis, performed in 2019. Six types of adverse childhood experiences were available in the data set, which were combined to create a dichotomous variable with any adverse experience counted as “yes.” Decreased renal function was defined as estimated glomerular filtration rate <60 mL/minute/1.73 m2. Main outcome was all-cause mortality. Cox proportional hazards models were performed to examine four combinations of adverse childhood experiences and decreased renal function associated with overall survival (neither, adverse childhood experiences only, decreased renal function only, or both) controlling for covariables.
Results:
In fully adjusted models, adverse childhood experiences and decreased renal function were associated with increased all-cause mortality relative to neither (hazard ratio=2.85, 95% CI=1.30, 6.25). Decreased renal function only and adverse childhood experiences only were not significantly associated with all-cause mortality (hazard ratio=1.14, 95% CI=0.64, 2.04 and HR=1.55, 95% CI=0.44, 5.41, respectively). When using decreased renal function as the reference group, coexisting adverse childhood experiences and decreased renal function was associated with 64% increased risk of all-cause mortality, though this relationship was not statistically significant.
Conclusions:
Coexistence of adverse childhood experiences and decreased renal function is associated with higher all-cause mortality compared with individuals with neither adverse childhood experiences nor decreased renal function and may be associated with higher all-cause mortality compared with decreased renal function alone. Future research is needed to better understand this potential association.
INTRODUCTION
Chronic kidney disease (CKD), defined as abnormal kidney function present for more than 3 months, affects 37 million U.S. adults.1,2 CKD, one of the leading causes of death in the U.S. and worldwide, is commonly caused by diabetes and hypertension.2,3 Management of CKD is complex and challenging as it is often focused on managing concordant comorbid diseases such as diabetes and hypertension to prevent complications, progression of disease, and mortality. Though risk factors for CKD include diabetes, hypertension, and heart disease, there is increasing evidence supporting the role of social determinants of health on CKD risk and outcomes.4,5
Social determinants of health are “conditions in which people are born, grow, live, work and age,” which include socioeconomic factors, psychosocial factors, neighborhood and built environment, political, economic and cultural factors.6,7 Social determinants of health exert an influence on adult health through both distal and proximal factors and are particularly salient for understanding chronic disease burden from a lifecourse perspective.8 Evidence suggests that social determinants of health have a unique interplay with biological factors that may predispose individuals to have worse health outcomes,9,10 including diabetes outcomes,11 hypertension,12 and kidney disease.4,5 For example, adverse childhood experiences (ACEs) are social determinants of health that have been shown to confer risk for adult morbidity and early mortality.7,13,14–19 The relationship between ACEs and mortality is thought to be related to exposure to adverse events during a sensitive developmental period lending to a toxic stress response.13,20 This ensuing toxic stress response is central to chronic disease development21,22 and psychological distress such as self-harm23 and health risk behaviors,14 ultimately increasing risk for early mortality.24
As they occur prior to age 18 years and can be direct (sexual, physical, or verbal abuse and neglect) or indirect (household dysfunction such as substance abuse, incarcerated relative, mental illness, mother treated violently, and household challenges such as family instability and financial strain), ACEs are considered distal influences on adult health.20,25 ACEs, though occurring during childhood, can have detrimental effects on adult health.13,14,16,21 The literature is well established on the association between ACEs and a number of the leading causes of death in the U.S., namely diabetes, hypertension, chronic respiratory disorders, stroke, kidney disease, and heart disease.13,14,16,21 In addition to being associated with the leading causes of death, recent evidence shows that individuals who have a history of ACEs and are living with a chronic disease in adulthood, such as diabetes, may have a greater mortality risk compared with individuals who do not experience ACEs and do not have a chronic disease.19 For example, a recent study examining the effect of cooccurring ACEs and diabetes on mortality found that during a 20-year follow-up period, individuals reporting a history of ACEs, who also had a diagnosis of diabetes, had a twofold increased risk of early mortality compared with individuals who did not have a history of ACEs and had diabetes.19 As diabetes is one of the leading causes of CKD, understanding whether ACEs confer similar mortality risk among individuals with CKD is greatly needed.
Overall, the relationship between ACEs and CKD is a widely understudied area.15 Although evidence suggests that prevalence, as well as risk of kidney disease are higher among those who experience ACEs,13,26 no study has examined the influence of coexisting ACEs and CKD on mortality risk in individuals with kidney disease.15 Therefore, the aim of this study is to examine the influence of coexisting ACEs and decreased renal function (DRF) on all-cause mortality in a nationally representative sample. The first hypothesis is that the coexistence of ACEs and DRF is associated with increased risk of all-cause mortality compared with individuals with neither condition after adjusting for relevant confounders. In addition, the secondary hypothesis is that the coexistence of ACEs and DRF is associated with an increased risk of mortality compared with individuals with only DRF.
METHODS
Study Population
Data from the national survey of Midlife Development in the United States (MIDUS) was used for this study.27 The collective aim of MIDUS is to investigate the role of behavioral, psychological, and social factors in age-related variations in health and well-being in a national sample of U.S. adults. Based on the success of MIDUS 1 (1995–1996), the National Institute on Aging awarded a grant to the Institute on Aging at the University of Wisconsin-Madison in 2002–2006 to carry out a longitudinal follow-up of MIDUS 1 respondents. The objectives of this research were to repeat the comprehensive assessments obtained in all of the original content areas, plus launch new areas of biological and neurological assessment. The study was extended for a third round of funding (2011–2016), with the objective of expanding the MIDUS sample. All three waves of the longitudinal MIDUS study were used for this study as different variables were collected in each wave. Only those with serum creatinine data collected during Wave 2 comprehensive biomarker assessment project were included in the cohort as determination of whether an individual had decreased estimated glomerular filtration rate (eGFR). ACE variables were collected in Waves 1 and 2, and mortality was collected in Wave 3. The data analysis took place in 2019 and the data are publicly available through the Inter-university Consortium for Political and Social Research. Fifty participants without complete ACE information were excluded. The final cohort for this study was 1,205 (Appendix Figure 1).
Measures
The ACEs Study Questionnaire21 was used to identify measures of adverse events experienced during childhood. The MIDUS study collected information on a number of possible ACEs included in the Felitti et al.21 definition of ACEs, as well as additional questions available in MIDUS to examine family instability and financial strain found in the extant literature using MIDUS to examine ACEs.28–30 Therefore, a combined set of ACEs categories was created, which included: emotional abuse, physical abuse, sexual abuse, substance abuse by parents during childhood, family instability, and financial strain. Self-reported questions used to create individual ACEs categories are shown in Table 1. Each type of ACE was then dichotomized to indicate exposure. A final dichotomized ACEs variable was created to indicate “yes” if an individual responded positively to any of the six categories, and “no” if they responded negatively to all six categories.

In this study, DRF was defined as estimated eGFR <60 mL/minute/1.73 m2 and was calculated using the CKD Epidemiology Collaboration,31 the recommended formulae per the Kidney Disease Improving Global Outcomes guidelines. Serum creatinine was used to calculate eGFR, a one-time collection in the biomarker project. The biomarker project did not collect urine albumin, as such urine albumin to creatinine ratio was not calculated.
Demographic variables included sex, age (dichotomized as 35–59 years and 60–86 years based on the mean age), and race (dichotomized as white and ethnic minority). Comorbidity was based on self-reported medical conditions collected during the Biomarker project. Participants were asked the following questions: Have you ever had any of the following conditions/illness? and If yes, was it diagnosed by a physician? To conserve power in the model, comorbidities could not be added individually. Instead, comorbidity burden was investigated based on a count of six self-reported clinically relevant comorbidities in the data set: hypertension, diabetes, cardiovascular disease, cancer, cholesterol problems, and depression. Based on the importance of specific comorbidities, high blood pressure and diabetes, these conditions were included as individual comorbidities in the fully adjusted model.
Mortality status was based on data collected at the time of Wave 3. The mortality status was collected from three general source categories: (1) tracing conducted by University of Wisconsin Survey Center before, during, and after fielding; (2) formal National Death Index searches; and (3) longitudinal sample maintenance.32 As the data set did not include cause of death, the outcome of interest for this study was all-cause mortality. All participants were followed from the date biomarker data was collected until death or end of follow-up date (May 2015, the latest death date available in the mortality data). Mortality data included known month and year of death; the middle of the month (15th) was used as the day to construct the date. The average follow-up time was 8.3 (SD=1.6) years.
Statistical Analysis
The primary independent variable was based on ACEs and DRF definitions to define four sample population groups: (1) no ACEs no DRF, (2) ACEs only, (3) DRF only, (4) ACEs and DRF. Baseline information was compared among these four groups using chi-square tests for categorical and ANOVAs for continuous variables.
A univariate Cox proportional hazard model was first developed to examine whether the four combinations based on ACEs and DRF coexistence was associated with overall survival. Unadjusted survival curves were then plotted from the univariate cox model with no ACEs/no DRF as the reference category. Secondly, multivariable Cox proportional hazard models were constructed by first adjusting for demographic variables including age, sex, and race; then by adjusting for demographic variables and comorbidities. Finally, unadjusted and adjusted Cox proportional hazard models were run with DRF as the reference category.
Risk-adjusted survival curves were plotted from the fitted Cox model using the corrected group prognosis method. In the corrected group prognosis method, survival curves were first calculated for each of the unique combinations of covariates using the fitted Cox model,33 the average survival was then calculated with weights proportional to the number of individuals at each covariate level.
Results were considered significant for p<0.05. All analyses were performed with SAS, version 9.4.
RESULTS
The longitudinal sample included 1,205 adults, aged 35–86 years. Table 2 provides sample baseline demographics. The cohort’s median age was 57 (IQR, 49–65) years, of which 57% were female, and 79% white. Overall, 71% reported having ACEs and approximately 7% had DRF. The mean eGFR of the cohort was 87.6 mL/minute/1.73 m2. Twenty-seven percent of this cohort who reported no history of ACEs did not have DRF (“no ACEs no DRF”), 66% of the cohort reported only having a history of ACEs (“ACEs only”), 2% of the cohort had DRF without a history of ACEs (“DRF only”), and 5% of the cohort who reported a history of ACEs also had DRF (“ACEs and DRF”).

Table 3 provides information on univariate and multivariable Cox proportional hazard models. In the unadjusted model, compared with individuals who did not have a history of ACEs and also did not have DRF, those individuals who only had a history of ACEs (hazard ratio [HR]=1.10, 95% CI=0.63, 1.92) and those who only had DRF (HR=2.86, 95% CI=0.84, 9.78) were not significantly different in mortality. However, individuals who had a history of ACEs and also had DRF, had a fourfold higher mortality risk (unadjusted HR=4.69, 95% CI=2.24, 9.83) compared with individuals who did not have a history of ACEs and did not have DRF. In fully adjusted models, individuals with coexisting ACEs and DRF maintained a twofold increase in mortality risk (HR= 2.85, 95% CI=1.30, 6.25). Those who only had DRF and those who only had a history of ACEs did not have a significantly associated all-cause mortality risk (HR=1.14, 95% CI=0.64–2.04 and HR=1.55, 95% CI=0.44, 5.41, respectively). When using DRF as the reference group, those with coexisting ACE and DRF had a 64% increased risk of all-cause mortality, though this relationship was not statistically significant (HR=1.64, 95% CI=0.46, 5.80). This increased risk of mortality remained after adjustment but was not significant (HR=1.72, 95% CI=0.48, 6.11). Figure 1 shows the adjusted survival curves by using the corrected group prognosis method for the four groups over time.

DISCUSSION
This study found, consistent with the study hypothesis, that after adjusting for demographics and comorbidities, individuals with coexisting ACEs and DRF had a twofold increased risk for all-cause mortality compared with those with neither. Contrary to the second hypothesis, having coexisting ACEs and DRF was not associated with higher mortality compared to those having DRF alone.
The current findings suggest that individuals with coexisting ACEs and DRF have significantly higher mortality risk compared with individuals with neither ACEs nor DRF. The Kaplan–Meier curve suggests that individuals with coexisting ACEs and DRF may have a more severe drop in survival in comparison to other groups; however, given the preliminary nature of this analysis, additional investigation into this relationship is warranted. Although existing evidence supports the exacerbating role that ACEs may have on the health status of individuals living with a chronic illness and its association with early mortality, these results serve as preliminary findings highlighting the influence of ACEs on mortality specifically among individuals with kidney disease.19 Though the mechanisms driving the observed higher mortality rate in individuals with coexisting ACEs and DRF remains unclear, evidence suggests that the prolonged stress response resulting from experiencing ACEs may underlie many biological processes leading to what has been referred to as “clustered metabolic risk” and increasing risk for early mortality.34,35 Coexisting ACEs and DRF may serve to compound existing health vulnerabilities leading to early mortality; however, more fully powered studies with additional measures are needed to tease out this association and the underlying mechanisms. In addition, evidence suggests that increased risk of early mortality may relate to factors during the embryonic and fetal phase of life.36,37 The impact of these factors on birth weight and disease susceptibility of an individual during their entire life is a phenomenon known as “fetal Programming.”36,37 Fetal programming has been shown through a number of epidemiologic studies to have an influence on chronic disease incidence and mortality.36,37 This relationship is another possible mechanism to explain the results of this study.
Interestingly, this study did not find a significant association between early mortality among those who had a history of ACEs only or DRF only. This contrasts with the existing evidence which shows an association between ACEs and early mortality.24,38,39 Specifically, individuals with a high number of ACEs have been shown to be at risk for premature death.17 In a study of more than 17,000 adults, cumulative exposure to ACEs was associated with a likelihood of dying 20 years early compared with individuals with no ACEs.17 Additionally, the relationship between ACEs and premature mortality has been found independent of adult mediating factors such as education, social class, BMI, smoking status, and alcohol consumption, where exposure to two or more ACEs was associated with 57%–80% increased risk of death.34 The lack of association seen in the present study may relate to the small sample size in the DRF group and large proportion of individuals who reported ACEs in this particular sample, which limits variability, or the broad definition of ACEs, which could lead to very different individuals categorized together. These findings should be interpreted within the context of prior work on ACEs and suggest future work in this area is needed.
These study findings have implications for clinical care. Clinically, although ACEs may not be the primary concern of a nephrologist faced with the complex management of concordant comorbid diseases such as diabetes and hypertension,40 the findings of this study underscore the significance of early recognition of ACEs history in individuals with DRF during healthcare delivery. Early recognition and screening for ACEs has the potential to mitigate its negative impact on an individual’s lifecourse health and health outcomes.41 There is growing evidence to support that social determinants of health such as ACEs impact physical and mental health, increase utilization of health care, and as such increase healthcare cost.13,14,21,33,42 Furthermore, the existing literature on ACEs has shown that the presence of ACEs confer risk for poor health behaviors in adulthood as well as morbidity and chronic diseases such as diabetes and hypertension.43 Consequently, this could increase the risk for kidney disease, the potential for complications, and or progression of disease.43 Taken together, for healthcare providers, specifically primary care physicians and nephrologists, an ACE-informed practice may be an important consideration when using patient history and contextual factors of patients’ environments to inform management options.15 Additionally, as providers are often uncomfortable screening for conditions without a plan for treatment, it is recommended that ACE screening is accompanied with referral pathways and provision of evidence-based treatment resources.41
Limitations
Despite the novelty of this study, it is not without limitations. First, the study population was middle age adults so prevalence estimates for DRF may be lower than national estimates which are based on a population level that includes elderly adults known to have the highest prevalence of disease. Second, based on the variables available in the data set, CKD could not be defined, and decreased renal function may not be the same population. Third, though a large proportion of the sample had ACEs, the group with “DRF only” was small so estimates may not be stable. Fourth, 8 years may not be enough time to capture mortality in this study population as DRF could be suggestive of acute kidney injury or future CKD. Fifth, because of the small overall sample and the small sample of individuals in the DRF only group, several covariates could not be included in the models. Sixth, the data set does not have information on parental risk factors, which could potentially affect mortality risk in individuals with DRF. Finally, this data set does not include information on CKD awareness which is an important factor for disease outcomes. Future studies should investigate a larger population-based sample controlling for additional cofounding factors, following participants for a longer period of time, investigating specific types of ACEs, and collecting information on awareness of and treatment for disease. Studies should also collect multiple serum creatinine collection over time to allow investigation of CKD and change in eGFR within a CKD population.
CONCLUSIONS
This longitudinal study of U.S. adults found that coexistence of ACEs and DRF was associated with higher all-cause mortality compared with individuals with neither ACEs nor DRF. These results serve as preliminary findings to understanding the influence of ACEs on health status among individuals with DRF. Future work is needed that focuses on the mechanistic factors driving this relationship as well as the influence of specific ACEs among this population.
