Abstract
Introduction
Poor sleep quality is associated with reduced health-related quality of life (HRQL) for children with Acute Lymphoblastic Leukemia (ALL). Research has yet to evaluate how components of child sleep quality uniquely contribute to HRQL beyond demographic characteristics. This study evaluates features of sleep and the relationship between sleep and HRQL for children in the maintenance phase of ALL treatment.
Methods
89 caregivers (ages 20-52, M=35.95, SD=7.10) of children with ALL (ages 3-12, M=5.73, SD=2.21; 13.76 months from diagnosis) completed demographic questionnaires and reports of child sleep quality (Child Sleep Habits Questionnaire; CSHQ), and 64 caregivers reported on child HRQL (Pediatric Quality of Life Inventory). Descriptive statistics were calculated. T-tests compared CSHQ subscales to ratings of healthy normative values. Pearson correlations evaluated associations between sleep and overall HRQL. Hierarchical regression assessed whether CSHQ subscales uniquely predicted HRQL beyond demographic characteristics.
Results
This sample reported greater bedtime resistance [t(88)=6.413, p<.001], sleep onset delay [t(88)=3.180, p=.002], sleep anxiety [t(88)=4.271, p<.001], night awakenings [t(88)=6.031, p<.001], parasomnias [t(88)=3.900, p<.001], and daytime sleepiness [t(87)=1.781, p=.078] than normative values, although sleep duration [t(88)=1.781, p=.078] and sleep disordered breathing (SDB) [t(88)=-.061, p=.951] did not differ. HRQL was related to SDB (r=-.289, p=.021), bedtime resistance (r=-.263, p=.036), and total sleep score (r=-.34, p=.006). The regression model with SDB and bedtime resistance explained 24.2% of variance but was not significant [F(6,31)=1.651, p=.167].
Conclusion
Caregiver ratings showed greater sleep impairments for children in this sample than of norms. Sleep subscales were associated with HRQL, but did not predict HRQL beyond demographic factors. Caregiver reports of child sleep and HRQL may vary depending on when during the monthly chemotherapy cycle questionnaires were completed. SDB did not differ from normative values but was related to HRQL, suggesting the need to screen for SDB symptoms to potentially improve child outcomes.

Abstract
Abstract
Introduction
Fear of cancer recurrence is common in young adults with cancer and also related to poorer psychological outcomes. Sleep may be disrupted by anxious thoughts about cancer, causing long-term psychological distress. Thus, the current study tests sleep as a putative mediator of the association between fear of cancer recurrence and overall psychological distress in young adult cancer survivors.
Methods
In a national cross-sectional survey of Canadians, 436 young adults diagnosed with cancer between the ages of 15-39 (current age range 20-39, m=32.39, SD=4.70; 88% female) completed the Pittsburgh Sleep Quality Index, the Fear of Cancer Recurrence Inventory—Short Form, and the Kessler 10 Distress Inventory. Mediation was estimated using PROCESS. Age, sex, and on/off treatment status were entered into models as covariates.
Results
In the current sample, average fear of cancer recurrence was above the clinical cut-point (m=22.92, SD=6.84), psychological distress was high (m=25.18, SD=7.81), and sleep quality was poor (m=9.11, SD=3.95). Females reported significantly higher fear of cancer recurrence than males [F(1, 435)=15.49, p <.001]. Patients on treatment reported significantly higher fear of cancer recurrence [F(1,435)=11.43, p=.001], poorer sleep quality [F(1,435)=6.48, p=.011], and greater psychological distress [F(1,435)=4.73, p <.001] than patients off treatment. Using a bootstrapping model with covariates, higher fear of cancer recurrence was related to poorer sleep quality and, in turn, higher psychological distress as indicated by the indirect effect’s confidence interval not containing 0 (indirect effect=.13; 95%CI=0.081, 0.189).
Conclusion
Sleep quality may play an important role in connecting the common experience of fear of cancer recurrence to psychological distress in young adult cancer survivors. Future longitudinal research is needed to examine this possible mediator of young adult cancer patients’ psychological distress outcomes over time.

0981 Sleep Practices In Pediatric Cancer—Does Sleep Hygiene Matter For Reducing Cancer Symptom Burden? Sleep 2020.

Abstract
Abstract
Introduction
Sleep disturbances are common during pediatric cancer treatment and recent evidence suggests a correlation between sleep and symptom burden. Improving nighttime sleep may impact patients’ ability to cope with symptoms. The current study tests the interaction between sleep hygiene and sleep disturbances in predicting cancer-related symptoms to determine if the relationship between sleep and symptoms is different for patients with better sleep hygiene.
Methods
102 caregivers of children with cancer (ages 5-17, M=10.12, SD=4.02; 58% female) completed parent-proxy Pediatric Sleep Practices Questionnaire (yielding routine consistency and sleep opportunity scores) and measures of cancer-related symptoms (PROMIS Sleep Disturbance, Fatigue, and Pain Interference; PedsQL—Cancer Module-Nausea subscale). The interaction between sleep disturbances and sleep hygiene (consistency, opportunity) on each symptom (pain, nausea, fatigue) were tested using PROCESS moderation.
Results
81% of caregivers report that their child receives sufficient sleep but only 12% reported regular consistent sleep patterns/routines. Sleep opportunity was not related to sleep disturbances or cancer-related symptoms, but more routine consistency was related to fewer sleep disturbances (r=.30, p=.003). The interaction between sleep disturbances and routine consistency significantly predicted pain interference [R2=.16, F(3, 98)=6.37, p<.001; Bint =-0.17, p=.028] and nausea [R2=.16, F(3, 98)=6.47, p<.001; Bint=0.46, p=.004]. The interaction between sleep disturbances and sleep opportunity significantly predicted nausea [R2=.15, F(3, 98)=5.76, p=.001; Bint =0.68, p=.016] but not pain interference. Both interaction models predicting fatigue were not significant.
Conclusion
The sleep/pain and sleep/nausea relationships are stronger in patients with more consistent sleep routines and the sleep/nausea relationship is also stronger in patients with sufficient/well-timed sleep opportunities. Sleep and fatigue were moderately related across all levels of both sleep hygiene components. Clinical interventions that target sleep hygiene together with sleep disturbances such as nighttime awakenings and poor sleep quality may be more effective in addressing cancer-related symptoms such as pain and nausea.

Abstract
Abstract
Introduction
Perspectives on co-sleeping vary by family cultural background and socio-demographic characteristics; furthermore, families may choose to co-sleep based on family values or out of necessity. To better understand the role of co-sleeping in young children from ethnic minority backgrounds, the current study sought to test the relationship between co-sleeping and sleep outcomes in an urban early childhood setting.
Methods
141 Parent-child dyads with children aged 1-5 years old (N=141,50.4% female, M=4.01 [SD=1.05]; 41% African American; 41% Latinx; median income $20-30,000) were recruited through an urban preschool. Parents completed demographic information and the Brief Child Sleep Questionnaire, which yielded insomnia and sleep hygiene indices. Step-wise regressions were used to examine the relationship between sleeping location and sleep outcomes (insomnia, sleep health, and child sleep quality), controlling for child age.
Results
Approximately half of the sample (n=71) reported that their child sleeps in a space shared by caregivers or siblings. Co-sleeping did not differ by race/ethnicity [χ 2(3)=1.45, p=.694], child age [F(1, 140)=2.15, p=.145], or income [χ 2(5)=7.05, p=.217]. Controlling for age, insomnia was higher in co-sleeping children [F(2,140)=4.10, p=.019], although sleep location was not a significant independent predictor. Sleep hygiene [F(2,140)=2.39, p=.095] and sleep quality [F(2,139)=0.94, p=.394] did not differ by sleeping location, when controlling for age.
Conclusion
Co-sleeping was common but was not related to sociodemographic factors as described in prior research. Controlling for age, co-sleeping predicted higher insomnia scores suggesting that co-sleeping may be related to symptoms of behavioral insomnia. Sleep hygiene practices and sleep quality did not differ by sleeping location, suggesting that in children without behavioral insomnia symptoms, co-sleeping may not affect sleep. Future studies that seek to better understand caregiver preference and intentions regarding co-sleeping may be important to intervention development seeking to improve behavioral insomnia in ethnic/minority samples.
