The Impact of Hematologic Cancer and Its Treatment on Physical Activity Level and Quality of Life Among Children in Mainland China: A Descriptive Study

Agreement between quality of life assessed using family proxy and child self-reports among children with hematologic malignancy

Evidence-based literature recognizes that the different degrees of agreement between a child self-report and a proxy-report depend on the characteristics of the domains, the child's age and illness, the proxy's own perspective on QoL, and family attendance during the child's hospitalization. This study aims to determine the degree of agreement between proxy-reports and child self-reports on quality of life (QoL) for children with hematologic malignancy ranging in age from 5 to 18 years who are undergoing treatment. We retrieved clinical QoL data from a study titled "Dynamic change in QoL for Vietnamese children with hematologic malignancy" from April 2021 to December 2022. To evaluate the magnitude of agreement between self-reports and proxy-reports, intraclass correlation coefficients (ICCs) for 259 pairs of measurements were quantified. Using independent t tests, the mean differences between self-reports and proxy-reports were tested. Moderate agreement was consistent through all age groups for five subscales, including physical, psychosocial, pain, nausea, and procedural anxiety (ICCs ranged from 0.53 to 0.74). The weakest agreement appeared in two groups, subjects aged 5-7 years and 13-18 years on six domains (school, treatment anxiety, worry, cognitive problems, perceived physical appearance, and communication) (-0.01 to 0.49). Child self-rating was consistently higher than that of proxies for the physical, emotional, and nausea domains among children aged 5-7 years and for procedural anxiety, treatment anxiety, and cognitive problems among children aged 8-12 years.    Conclusion: The agreement level of self-reports and proxy-reports was differently distributed by child age and the PedsQL domains. The proxy children agreement on QoL among children with hematologic malignancy was divergent according to the different age groups, which could potentially be explained by proxy-child bonding at different stages of childhood development. Our recommendation for future studies is to explore children's age as a potential factor influencing proxy agreement on QoL among children with cancer. What is Known: • Children and their proxies may think differently about quality of life (QoL). • Comparing two sources of data (i.e., child and proxy) on aspects of QoL can help identify the discrepancies between children's perceptions of their QoL and their parents' perceptions. This can be useful in terms of identifying potential areas for improvement or concern and may also be helpful in making decisions about treatment and care. What is New: • Our study results demonstrated that proxies who comprised children aged 5-7 years or 13-18 years reported differently among domains that cannot be expressed verbally or with body language, including cognitive problems, perceived physical appearance, and communication. • Children generally perceived their QoL to be better than their proxies. Therefore, a more comprehensive understanding of children's QoL may require the consideration of multiple sources of data from various perspectives.

Can performance status mediate the relationship between therapy-related symptoms and health-related quality of life in children with cancer? A mediation model

PURPOSE

Understanding the interplay among health-related quality of life (HRQoL), therapy-related symptoms, and performance status can offer insights into potential strategies to enhance HRQoL for pediatric cancer patients. This study aimed to examine the mediating effect of performance status on the relationship between symptom burden and HRQoL in children and adolescents with cancer.

METHOD

A cross-sectional study was conducted. Participants were recruited from two tertiary hospitals located in Guangzhou, China. HRQoL, therapy-related symptoms, and performance status were assessed using the DISAKIDS Chronic Generic Measure (DCGM-37), Therapy-Related Symptom Checklist for Children (TRSC-C), and Lansky Play Performance Scale (LPPS), respectively.

RESULTS

A total of 287 children with cancer (aged 11.08 ± 2.34 years) were included. The DCGM-37 scores were 59.70 ± 9.64. Emotion (56.45 ± 14.56) and physical limitations (58.59 ± 15.38) were the most affected domains. The number of symptoms experienced was 12.49 ± 5.95. The DCGM-37 demonstrated strong negative correlations with the TRSC-C (r = -0.60, P < 0.001) and number of symptoms (r = -0.62, P < 0.001), but mild-to-moderate negative correlations (r -0.16∼ -0.42, P < 0.05) with individual symptoms. The TRSC-C demonstrated an indirect effect on the DCGM-37 via the LPPS (Bootstrap-corrected standardized β = -0.05, 95 % CI -0.10∼ -0.01; SE = 0.02). Additional analysis showed that tripping/falling (OR = 4.02, 95 % CI 2.02-7.98; P < 0.001) and sore mouth (OR = 2.38, 95 % CI 1.56-3.64; P < 0.001) were associated factors for presenting poor performance status in children undergoing acute chemotherapy.

CONCLUSIONS

The accumulated symptom burden, rather than individual symptoms, weighs heavily on the HRQoL. Performance status partially mediated the relationship between symptom burdens and HRQoL among these patients.

Supervised Exercise Interventions in Childhood Cancer Survivors: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background: Childhood cancer survivors (CCSs) may suffer from a multitude of health impairments, resulting in a compromised quality of life (QoL). This review’s objective was to examine CCSs’ adherence to supervised exercise training interventions and the impact of these interventions on health outcomes. Methods: The following databases were searched in May 2022: PubMed, Embase, Cochrane Library, and Web of Science. The included studies were limited to randomized controlled trials (RCTs), published in English involving CCSs aged 18 years and below. Results: Nine RCTs (n = 642 participants) were included in the systematic review, and seven of them (n = 551 participants) were included in the meta-analysis. Both the mean retention rate and adherence to the supervised exercise interventions were 87%. Supervised exercise interventions significantly improved muscle strength (standardized mean difference (SMD) = 1.42, p = 0.03), level of daily physical activity (SMD = 1.05, p < 0.001), body mass index (BMI) (mean difference (MD) = 1.06, p = 0.03), and fatigue (SMD = −0.44, p < 0.001), while there was no statistical significance in the quality of life (QoL) (SMD = 0.21, p = 0.20). Conclusions: The adherence of CCSs to supervised exercise interventions is high, and supervised exercise interventions are safe and effective.

Individual, Interpersonal, and Home Environmental Factors Influencing Health Behaviors Among Chinese Childhood Cancer Survivors: A Structural Equation Analysis

BACKGROUND

Childhood cancer survivors (CCSs) are at increased risk of chronic health conditions, which could be controlled with health behaviors. However, the health behaviors and related factors of Chinese CCSs remain unclear.

OBJECTIVE

The aims of this study were to examine multiple health behaviors among Chinese CCSs and explore the individual, interpersonal, and home environmental factors affecting health behaviors.

METHODS

This cross-sectional study recruited 204 participants from 3 grade-A tertiary hospitals in Guangzhou, China. Participants provided data on health behaviors (smoking, drinking, drug use, screen time, internet addiction, dietary behaviors, physical activity, and sleep behaviors) and their determining factors. Structural equation modeling was used to analyze the data.

RESULTS

Chinese CCSs reported low rates of smoking, drinking, and drug use (0%-6.4%), but only 51% of survivors met screen time recommendations, and 24.5% of them had Internet addiction. Few survivors reported frequent soft-drink, sugar, and fast-food intake (2.0 to 7.4%), but many were finicky eaters (55.4%) or seldom drank milk (41.7%). In addition, 67.6% and 47.5% of survivors did not meet physical activity and sleep time recommendations. Childhood cancer survivors' health behaviors were influenced by the individual (age, education level, and time since diagnosis), interpersonal (peer and family support), and home environmental (residential location, parents' educations level, and household income) factors.

CONCLUSIONS

There were suboptimal health behaviors among Chinese CCSs. Targeted interventions should consider their individual, interpersonal, and home environmental factors.

IMPLICATIONS FOR PRACTICE

Knowledge of health behaviors and related factors of Chinese CCSs would help healthcare professionals develop further interventions to improve their care of this population.

Dietary behaviours, physical activity and quality of life among childhood cancer survivors in Mainland China: A cross-sectional study

OBJECTIVE

To examine the dietary behaviours, physical activity (PA) and quality of life (QoL) of childhood cancer survivors (CCS) in Mainland China and explore the relationships between these behaviours and QoL.

METHODS

This cross-sectional study recruited 181 CCS from three Grade-A tertiary hospitals in Guangzhou. Survivors completed questionnaires assessing their dietary behaviours, PA and QoL.

RESULTS

Only 2.2%, 7.7% and 2.2% of CCS reported frequent soft drinks, sugar and fast food intake, which were lower compared to CCS in Western studies. Most survivors (72.9%) failed to drink milk daily, and many (54.7%) were picky eating. Sixty percent of CCS reported less moderate-to-vigorous physical activity (MVPA) time than 60 min/day recommended by WHO. Picky eating was significantly associated with lower overall (p < 0.001), physical (p < 0.001) and psychosocial (p < 0.001) QoL. MVPA was significantly positively associated with overall (p < 0.05) and psychosocial (p < 0.01) QoL.

CONCLUSIONS

Chinese CCS engaged better dietary behaviours of less soft drinks, sugar and fast food consumption, but many were picky eaters and did not meet milk intake and PA recommendations. Early behavioural interventions aimed at increasing the dietary diversity and MVPA level of this population should be taken to improve their QoL.

Systematic review of the effectiveness of complementary and alternative medicine on nausea and vomiting in children with cancer: a study protocol

INTRODUCTION

Nausea and vomiting are two most common symptoms reported by children with cancer when they undergo active treatment. However, pharmacological treatment is not sufficient to manage these two symptoms, with over 40% of children still experience nausea and vomiting after receiving antiemetics. There has been an exponential growth of studies to demonstrate the effectiveness of different complementary complementary medicine (CAM) to control nausea and vomiting during cancer treatment. Appropriate application of CAM enhances the effectiveness of antiemetics, thus reducing the symptom burden on children as well as improving their general condition and quality of life during cancer treatment. Nevertheless, it remains unclear which CAM is the best approach to help children to prevent or reduce nausea and vomiting during and after cancer treatment. This paper describes a protocol for identifying, analysing and synthesising research evidence on the effectiveness of CAM on nausea and vomiting in children with cancer.

METHODS AND ANALYSIS

A total of 10 databases will be searched to identify appropriate literature: MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, CINAHL, PsycINFO, LILACS, OpenSIGLE, the Chinese Biomedical Literature Database, the Chinese Medical Current Contents and the Chinese National Knowledge Infrastructure. All randomised controlled trials which meet the inclusion criteria will be included. The primary outcome is the changes in nausea and vomiting either assessed by self-reported and/or objective measures. Review Manager 5.3 will be used to synthesise the data, calculate the treatment effects, perform any subgroup analysis and assess the risk of bias.

ETHICAL AND DISSEMINATION

The results will be presented at international conferences and published in peer-reviewed journals. As no individual data will be involved in this review, ethical approval is not required.
