The Contribution of Stress and Distress to Cardiovascular Health in Adult Survivors of Childhood Cancer.

ABSTRACT:

Background

Childhood cancer survivors are at risk for cardiovascular morbidity and mortality that is not fully explained by cancer-directed therapies. We examined the contribution of emotional stress and distress to cardiac health in adult survivors of childhood cancer.

Methods

Participants included 3,267 adult survivors enrolled in the St. Jude Lifetime Cohort Study [median (range) 29.9 (18.1-64.5) years of age; 7.7 (0-24.8) years at diagnosis; 48.4% female]. Survivors completed comprehensive medical assessments and standardized measures of depression, anxiety, posttraumatic stress symptoms (PTSS), and perceived stress. Cardiovascular-related conditions included hypertension, diabetes, dyslipidemia, cardiomyopathy, dysrhythmia, myocardial infarction (severity graded 0-4), and metabolic syndrome (yes/no). Multivariable modified Poisson models examined associations between symptoms of stress/distress and cardiovascular outcomes. Longitudinal associations between stress/distress and new-onset cardiovascular outcomes, defined as a change from grade ≤1 at initial evaluation to grade ≥2 at follow-up (median 3.9 years) were examined in 1,748 participants.

Results

In multivariable cross-sectional models, stress/distress was associated with hypertension [risk ratio (RR) = 1.24; 95% confidence interval (CI), 1.07-1.43], dyslipidemia (RR = 1.29; 95% CI, 1.03-1.61), and metabolic syndrome (RR = 1.35; 95% CI, 1.17-1.54) independent of known cardiovascular risk factors. In longitudinal models, stress/distress was associated with new-onset dysrhythmia (RR = 2.87; 95% CI, 1.21-6.78), perceived stress with hypertension (RR = 1.42; 95% CI, 1.04-1.95), and PTSS and anxiety with dyslipidemia (RR = 1.72; 95% CI, 1.13-2.62; RR = 1.54; 95% CI, 1.01-2.35, respectively).

Conclusions

Stress/distress is independently associated with adverse cardiovascular outcomes among childhood cancer survivors.

Impact

Improving psychological health may serve as a potential intervention target for optimizing cardiac health among childhood cancer survivors.

Project description:ImportanceCardiovascular disease is the leading noncancer cause of premature death among survivors of childhood cancer. Adult survivors of childhood cancer are largely managed by primary care practitioners (PCPs), and health care utilization patterns related to cardiovascular screening are not well described.ObjectiveTo examine screening and health care utilization among survivors of childhood cancer at high risk for cardiovascular complications.Design, setting, and participantsThis multicenter cross-sectional study included participants enrolled in a randomized clinical trial from 2017 to 2021. Abstracted documentation of participants' cancer history, cardiotoxic treatment exposures, and survivorship care plans were obtained from participants' PCPs spanning 2 years preceding trial enrollment. Participants were members of the Childhood Cancer Survivor Study cohort at elevated risk for ischemic heart disease or heart failure, enrolled in a randomized trial focused on improving cardiovascular risk factor control. Data were analyzed from November 2022 to July 2023.Main outcomes and measuresOutcomes of interest were numbers of PCP and specialist visits, cardiovascular risk factors (hypertension, dyslipidemia, and diabetes), risk factor screening, and cardiac testing. Multivariable logistic regression assessed characteristics associated with up-to-date cardiac testing at enrollment.ResultsOf 347 enrolled participants, 293 (84.4%) had evaluable medical records (median [range] age, 39.9 [21.5-65.0] years; 149 [50.9%] male) and were included in analyses. At baseline, 238 participants (81.2%) had a documented PCP encounter; 241 participants (82.3%) had undergone blood pressure screening, 179 participants (61.1%) had undergone lipid testing, and 193 participants (65.9%) had undergone diabetes screening. A total of 63 participants (21.5%) had echocardiography completed or planned. Only 198 participants (67.6%) had records referencing a cancer history. PCP documentation of prior cardiotoxic exposures was low compared with known exposures, including radiation therapy (103 participants [35.2%] vs 203 participants [69.3%]; P < .001) and anthracycline chemotherapy (27 participants [9.2%] vs 222 participants [75.8%]; P = .008). Few records referenced a need for cancer-related late effects surveillance (95 records [32.4%]). Independent factors associated with cardiac screening included documentation of increased cardiovascular disease risk (odds ratio [OR], 11.94; 95% CI, 3.37-42.31), a late-effects surveillance plan (OR, 3.92; 95% CI, 1.69-9.11), and existing cardiovascular risk factors (OR per each additional factor, 2.09; 95% CI, 1.32-3.31).Conclusions and relevanceThis cross-sectional study of adult survivors of childhood cancer at increased risk of cardiovascular disease found low adherence to recommended cardiac testing and documentation of risk for these individuals. Improving accuracy of reporting of survivors' exposures and risks within the medical record may improve screening.

Project description:OBJECTIVE:Sleep disorders are associated with psychological and physical health, although reports in long-term survivors of childhood cancer are limited. We characterized the prevalence and risk factors for behaviors consistent with sleep disorders in survivors and examined longitudinal associations with emotional distress and physical health outcomes. METHODS:Survivors (n = 1933; median [IQR] age = 35 [30, 41]) and siblings (n = 380; age = 33 [27, 40]) from the Childhood Cancer Survivor Study completed measures of sleep quality, fatigue, and sleepiness. Emotional distress and physical health outcomes were assessed approximately 5 years before and after the sleep survey. Multivariable logistic or modified Poisson regression models examined associations with cancer diagnosis, treatment exposures, and emotional and physical health outcomes. RESULTS:Survivors were more likely to report poor sleep efficiency (30.8% vs 24.7%; prevalence ratio [PR] = 1.26; 95% confidence interval, 1.04-1.53), daytime sleepiness (18.7% vs 14.2%; PR = 1.31 [1.01-1.71]), and sleep supplement use (13.5% vs 8.3%; PR = 1.56 [1.09-2.22]) than siblings. Survivors who developed emotional distress were more likely to report poor sleep efficiency (PR = 1.70 [1.40-2.07]), restricted sleep time (PR = 1.35 [1.12-1.62]), fatigue (PR = 2.11 [1.92-2.32]), daytime sleepiness (PR = 2.19 [1.71-2.82]), snoring (PR = 1.85 [1.08-3.16]), and more sleep medication (PR = 2.86 [2.00-4.09]) and supplement use (PR = 1.89[1.33-2.69]). Survivors reporting symptoms of insomnia (PR = 1.46 [1.02-2.08]), fatigue (PR = 1.31 [1.01-1.72]), and using sleep medications (PR = 2.16 [1.13-4.12]) were more likely to develop migraines/headaches. CONCLUSIONS:Survivors report more sleep difficulties and efforts to manage sleep than siblings. These sleep behaviors are related to worsening or persistently elevated emotional distress and may result in increased risk for migraines. Behavioral interventions targeting sleep may be important for improving health outcomes.

Project description:The current study was performed to examine associations between childhood cancer therapies, chronic health conditions, and symptoms of emotional distress in adult survivors of childhood cancer.Participants included 5021 adult survivors of childhood cancer (mean age, 32.0 years [standard deviation, 7.6 years] with a time since diagnosis of 23.2 years [standard deviation, 4.5 years]) who completed measures assessing symptoms of anxiety, depression, and posttraumatic stress. Cardiac, pulmonary, and endocrine conditions were graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.03; grades 1-4). Structural equation modeling was used to examine hypothesized pathways between cancer treatment exposures, chronic health conditions, and symptoms of emotional distress. Multivariable models were used to estimate relative risks (RRs) for associations between chronic health conditions and distress.Survivors with cardiovascular, endocrine, or pulmonary conditions were found to have a significantly higher prevalence of emotional distress symptoms. In path analyses and multivariable models, significant effects were observed between endocrine (??=?.12 [P?=?.002] and RR, 1.3 [95% confidence interval (95% CI), 1.1-1.6]) and pulmonary (??=?.13 [P<.001] and RR, 1.4 [95% CI, 1.1-1.7]) conditions and depression, and between cardiac (??=?.13 [P?=?.001] and RR, 1.5 [95% CI, 1.2-1.8]) and pulmonary (??=?.15 [P<.001] and RR, 1.6 [95% CI, 1.3-2.0]) conditions and anxiety. All treatment-related chronic health conditions were found to be associated with posttraumatic stress symptoms (cardiac: ??=?.09 [P?=?.004] and RR, 1.3 [95% CI, 1.2-1.5]; endocrine: ??=?.12 [P<.001] and RR, 1.3 [95% CI, 1.2-1.5]; and pulmonary: ??=?.13 [P<.001] and RR, 1.4 [95% CI, 1.2-1.6]).Chronic health conditions resulting from childhood cancer therapies contribute to emotional distress in adult survivors. Targeted mental health screening efforts in this at-risk population appear warranted. Therapeutic approaches should consider the complex interplay between chronic health conditions and symptoms of emotional distress. Cancer 2017;123:521-528. © 2016 American Cancer Society.
