Association of Exercise Intolerance With Emotional Distress, Attainment of Social Roles, and Health-Related Quality of Life Among Adult Survivors of Childhood Cancer.

ABSTRACT:

Importance

Exercise intolerance is associated with increased risk for morbidity and mortality in childhood cancer survivors. However, an association between exercise intolerance and psychosocial outcomes has not been fully explored.

Objective

To examine the associations between exercise intolerance and emotional distress, attainment of social roles, and health-related quality of life in childhood cancer survivors.

Design, setting, and participants

A cross-sectional study including 1041 adult survivors of childhood cancer and 286 community controls in the St Jude Lifetime Cohort was conducted at St Jude Children's Research Hospital. The study was performed from April 1, 2012, to March 15, 2020.

Exposures

Exercise intolerance was defined as relative peak oxygen uptake less than 85% of age- and sex-estimated levels from maximal cardiopulmonary exercise testing.

Main outcomes and measures

Emotional distress was measured with the 18-item Brief Symptom Inventory-18, which includes overall Global Severity Index and depression, anxiety, and somatization subscales. Participants with T scores greater than or equal to 63 were classified as having elevated levels of distress. Social attainment was evaluated using patient-reported educational, employment, and marital status. Health-related quality of life was examined with the Medical Outcomes Survey Short Form-36. Participants with T scores less than or equal to 40 were classified as reporting poor health-related quality of life.

Results

Of the 1041 participants, 528 were women (50.7%). The prevalence of exercise intolerance among survivors (mean [SD] age, 35.5 [9.2] years) was higher than that among controls (age, 34.5 [10.0] years) (survivors: 634 [60.9%] vs controls: 75 [26.2%], P < .001). After adjusting for age at diagnosis and cardiopulmonary exercise testing, sex, race/ethnicity, smoking, physical activity, and exercise intolerance were associated with an increased risk for anxiety (prevalence rate ratio [PRR], 1.95; 95% CI, 1.20-3.16), somatization (PRR, 1.86; 95% CI, 1.23-2.80), and unemployment (PRR, 1.76; 95% CI, 1.23-2.52); an inverse association was noted with having a college degree (PRR, 0.67; 95% CI, 0.50-0.88). Exercise intolerance was associated with an increased the risk for scoring less than or equal to 40 on the physical component summary of the Medical Outcomes Survey Short Form-36 (PRR, 3.69; 95% CI, 2.34-5.84). These associations persisted when either cancer treatment exposures or chronic health conditions were added to the model.

Conclusions and relevance

The findings of this study suggest that exercise intolerance is independently associated with emotional distress, attainment of social roles, and health-related quality of life of long-term survivors of childhood cancer. The results also suggest that improving physiologic capacity may benefit general health and wellness, as well as emotional health, ability to participate in social roles, and health-related quality of life.

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.

Project description:ImportanceAdult survivors of childhood cancer are at excess risk for mortality compared with the general population. Whether exercise attenuates this risk is not known.ObjectiveTo examine the association between vigorous exercise and change in exercise with mortality in adult survivors of childhood cancer.Design, setting, and participantsMulticenter cohort analysis among 15 450 adult cancer survivors diagnosed before age 21 years from pediatric tertiary hospitals in the United States and Canada between 1970 and 1999 enrolled in the Childhood Cancer Survivor Study, with follow-up through December 31, 2013.ExposuresSelf-reported vigorous exercise in metabolic equivalent task (MET) hours per week. The association between vigorous exercise and change in vigorous exercise and cause-specific mortality was assessed using multivariable piecewise exponential regression analysis to estimate rate ratios.Main outcomes and measuresThe primary outcome was all-cause mortality. Secondary end points were cause-specific mortality (recurrence/progression of primary malignant neoplasm and health-related mortality). Outcomes were assessed via the National Death Index.ResultsThe 15 450 survivors had a median age at interview of 25.9 years (interquartile range [IQR], 9.5 years) and were 52.8% male. During a median follow-up of 9.6 years (IQR, 15.5 years), 1063 deaths (811 health-related, 120 recurrence/progression of primary cancer, 132 external/unknown causes) were documented. At 15 years, the cumulative incidence of all-cause mortality was 11.7% (95% CI, 10.6%-12.8%) for those who exercised 0 MET-h/wk, 8.6% (95% CI, 7.4%-9.7%) for 3 to 6 MET-h/wk, 7.4% (95% CI, 6.2%-8.6%) for 9 to 12 MET-h/wk, and 8.0% (95% CI, 6.5%-9.5%) for 15 to 21 MET-h/wk (P < .001). There was a significant inverse association across quartiles of exercise and all-cause mortality after adjusting for chronic health conditions and treatment exposures (P = .02 for trend). Among a subset of 5689 survivors, increased exercise (mean [SD], 7.9 [4.4] MET-h/wk) over an 8-year period was associated with a 40% reduction in all-cause mortality rate compared with maintenance of low exercise (rate ratio, 0.60; 95% CI, 0.44-0.82; P = .001).Conclusions and relevanceVigorous exercise in early adulthood and increased exercise over 8 years was associated with lower risk of mortality in adult survivors of childhood cancer.

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:BackgroundChildhood 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.MethodsParticipants 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.ResultsIn 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).ConclusionsStress/distress is independently associated with adverse cardiovascular outcomes among childhood cancer survivors.ImpactImproving psychological health may serve as a potential intervention target for optimizing cardiac health among childhood cancer survivors.
