Adverse Childhood Experiences (ACEs) in Newly-Diagnosed Childhood and Adolescent/Young Adult (AYA) Cancer Patients with Hematologic Malignancies

Background and Aims: Childhood and adolescent/young adult (AYA) cancer survivors are at increased risk for emotional distress, chronic health conditions, and premature mortality compared to peers with no cancer history. Some, but not all, of this increased risk is explained by cancer- and treatment-related exposures. Because cancer treatment remains necessary to achieve cure, it is critical to identify and target other factors to reduce sub-optimal outcomes. Adverse Childhood Experiences (ACEs) are traumatic events occurring during childhood, such as experiencing violence and/or neglect, which are associated with poor mental health, chronic health conditions, and premature mortality in the adult general population. Little is known on how ACEs impact health in children and AYAs with cancer. Research indicates that otherwise healthy individuals exposed to ACEs experience fewer adverse health outcomes if they possess resilience, which can be learned. This provides a potential target for intervention. This pilot study aimed to identify demographic characteristics associated with ACEs and resilience as well as associations between ACEs, resilience, and the presence of chronic medical conditions, mental health issues, and substance abuse in children and AYAs with cancer.

Methods: Childhood and AYA leukemia and lymphoma patients undergoing cancer treatment at the University of Chicago were included for analysis (N=38, 55.26% female, 50% non-Hispanic white, mean age at assessment 14.74±6.97 years). Participants ≤17 years old completed the study with one parent/caregiver. ACEs were measured using age-specific instruments adapted from the original ACEs study by Kaiser Permanente and the Centers for Disease Control and Prevention. Resilience was analyzed using age-specific instruments provided by the Resilience Research Centre, and resilience scores were categorized as low (≤62), moderate (63-70), high (71-76), and exceptional (≥77). For participants 0-11 years old, a parent/guardian completed the study on their behalf. 12-17 year old participants and their parent/guardian both completed the study, and participants over 18 completed the study alone. Descriptive statistics characterized demographic, biologic, treatment, and health behavior variables. The association between total scores for ACEs and resilience were measured using Pearson's correlation. Regression analysis assessed ACEs (logistic model) and resilience scores (linear model) adjusting for age, sex, race/ethnicity, household income, and insurance type. Participants were then stratified, and two sample t-tests compared potential outcomes based on ACE exposures.

Results: 23 participants (60.53%) reported prior ACEs (mean total number of ACEs 1.45±1.77; range 1-7), and the mean resilience score for participants was 73.76±9.61 (range 49-85) indicating high resilience overall. Regression analyses showed the odds of reporting ACEs increased with age (OR: 1.18; 95% CI: 1.02-1.37), while resilience scores decreased with age (β=0.76; t(32)=-2.74, p=0.01) holding other variables constant. Sex, race/ethnicity, household income, and insurance type were not associated with ACEs or resilience scores. There was a strong negative correlation between the total number of ACEs and resilience, r(36)=-0.57, p<0.01; the total number of ACEs explained 32% of the variation in resilience scores. Compared to participants who did not report prior ACEs, those with ACEs were more likely to report chronic medical conditions, t(31.41)=-2.47, p=0.02, prior psychiatric diagnoses or mental health issues, t(34.16)=-2.13, p=0.04, as well as substance abuse t(31.41)=-2.47, p=0.02.

Conclusions: ACEs were associated with endorsement of chronic medical conditions, mental health issues, and substance abuse in our sample of childhood and AYA patients currently receiving cancer treatment. As the total number of ACEs increased, resilience scores decreased for participants. The results of this study provide the groundwork for further investigations of ACEs and resilience in large cohorts of childhood and AYA cancer patients and survivors. This future work could provide valuable information for creating and implementing interventions designed for childhood and AYA cancer patients and survivors who have experienced ACEs, thus potentially reducing additional morbidity and premature mortality for these high-risk patients.
