Long-Term Maternal Mental Health after Spontaneous Preterm Birth.

OBJECTIVE: The aim of this study is to investigate whether a history of spontaneous preterm birth (SPTB) is associated with maternal depressive and anxiety symptoms, or psychosocial distress in the fifth decade of life. STUDY DESIGN: This is a secondary analysis of the PreCaris-study, a prospective observational study in which we included 350 women with a history of SPTB between 220/7 and 366/7 weeks of gestation and compared them to 115 women who had a term birth. Primary outcomes were the Depression and Anxiety scores measured using the Hospital Anxiety Depression Scale and Psychosocial distress assessed with the Distress Thermometer for Parents. Secondary outcomes were self-reported impact of the birth in daily life and psychosocial support after delivery. RESULTS: After a median of 13 years after delivery, no significant differences were found in primary outcomes. Significantly more women with a history of SPTB reported that the birth still had impact in daily life; adjusted odds ratio: 2.46 (95% confidence interval: 1.35-4.48). A total of 57 (16.3%) women after SPTB reported to have needed professional psychosocial support after delivery but did not receive it. These women more often had a high Anxiety score (p = 0.030), psychosocial distress (p = 0.001), and influence of birth in daily life (p = 0.000). CONCLUSION: There are no long-term effects on depressive and anxiety symptoms and psychosocial distress in women who experienced SPTB compared with women who had a full-term pregnancy. A significant part of the women who delivered preterm needed psychosocial support but did not receive it and were at higher risk of anxiety, psychosocial distress, and impact in daily life. We therefore recommend offering all women after SPTB psychosocial support after delivery. KEY POINTS: · No long-term effects on depressive and anxiety symptoms and psychosocial distress after SPTB.. · A total of 16.3% of the cases needed professional psychosocial support after delivery but did not receive it.. · This subgroup was at higher risk of anxiety symptoms, psychosocial distress, and impact on daily life..

Cognitive and Behavioral Development of 9-Year-Old Children After Maternal Cancer During Pregnancy: A Prospective Multicenter Cohort Study.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.This multicenter cohort study reports on the long-term effects of prenatal exposure to maternal cancer and its treatment on cognitive and behavioral outcomes in 9-year-old children. In total, 151 children (mean age, 9.3 years; range, 7.8-10.6 years) were assessed using a neurocognitive test battery and parent-report behavioral questionnaires. During pregnancy, 109 children (72.2%) were exposed to chemotherapy (only or in combination with other treatment modalities), 18 (11.9%) to surgery only, 16 (10.6%) to radiotherapy, one to trastuzumab, and 16 (10.6%) were not exposed to oncologic treatment. Mean cognitive and behavioral outcomes were within normal ranges. Gestational age at birth showed a positive association with Full Scale Intelligence Quotient (FSIQ), with the average FSIQ score increasing by 1.6 points for each week increase in gestational age (95% CI, 0.7 to 2.5; P < .001). No difference in FSIQ was found between treatment types (F[4,140] = 0.45, P = .776). In children prenatally exposed to chemotherapy, no associations were found between FSIQ and chemotherapeutic agent, exposure level, or timing during pregnancy. These results indicate a reassuring follow-up during the critical maturational period of late childhood, when complex functions develop and rely on the integrity of early brain development. However, associations were observed with preterm birth, maternal death, and maternal education.

Association of Chemotherapy Timing in Pregnancy With Congenital Malformation.

Importance: Chemotherapy during the first trimester of pregnancy should be avoided owing to the risk of congenital malformations. However, the precise gestational age at which chemotherapy can be initiated safely remains unclear. Objective: To assess congenital malformation rates associated with gestational age at initiation of chemotherapy among pregnant women with cancer. Design, Setting, and Participants: This multicenter cohort study evaluated all pregnant women who received chemotherapy between 1977 and 2019 registered in the International Network on Cancer, Infertility and Pregnancy (INCIP) database. Data were analyzed from February 15 to June 2, 2020. Exposures: Cancer treatment with chemotherapy during pregnancy. Main Outcomes and Measures: Analysis was focused on major and minor structural malformations in offspring, defined by EUROCAT, detected during pregnancy or at birth. Results: A total of 755 women in the INCIP database who underwent cancer treatment with chemotherapy during pregnancy were included in analysis. The median (range) age at cancer diagnosis was 33 (14-48) years. Among offspring, the major congenital malformation rate was 3.6% (95% CI, 2.4%-5.2%), and the minor congenital malformation rate was 1.9% (95% CI, 1.0%-3.1%). Chemotherapy exposure prior to 12 weeks gestational age was associated with a high rate of major congenital malformations, at 21.7% (95% CI, 7.5%-43.7%; odds ratio, 9.24 [95% CI, 3.13-27.30]). When chemotherapy was initiated after gestational age 12 weeks, the frequency of major congenital malformations was 3.0% (95% CI, 1.9%-4.6%), which was similar to the expected rates in the general population. Minor malformations were comparable when exposure occurred before or after gestational age 12 weeks (4.3% [95% CI, 0.1%-21.9%] vs 1.8% [95% CI, 1.0-3.0]; odds ratio, 3.13 [95% CI, 0.39-25.28]). Of 29 women who received chemotherapy prior to 12 weeks gestation, 17 (58.6%) were not aware of pregnancy, and 6 (20.7%) experienced a miscarriage (3 women [10.3%]) or decided to terminate their pregnancy (3 women [10.3%]). Conclusions and Relevance: This cohort study found that chemotherapy was associated with an increased risk of major congenital malformations only in the first 12 weeks of pregnancy. The risk of congenital malformations when chemotherapy was administered during the first trimester and the high number of incidental pregnancies during cancer treatment in the INCIP registry underscore the importance of contraceptive advice and pregnancy testing at the start of chemotherapeutic treatment in young women with cancer.

[Formula: see text]Long-term neurodevelopmental outcome after prenatal exposure to maternal hematological malignancies with or without cytotoxic treatment.

Data on the long-term neurodevelopmental outcomes of children exposed to hematological maternal cancer with or without treatment during pregnancy are lacking. A total of 57 children, of whom 33 males and 24 females, prenatally exposed to hematological malignancies and its treatment, were invited for neuropsychological and physical examinations at 18 months, 36 months, 6, 9, 12, 15 and 18 years of age. Oncological, obstetrical, neonatal and follow-up data of these children were collected. Parents were asked to complete questionnaires on their child's general health, school performances, social situation, behavioral development, executive functioning, and if their child receives supportive care. Non-Hodgkin lymphoma was diagnosed in 35.1%, Hodgkin lymphoma in 28.1%, acute myeloid leukemia in 15.8%, chronic myeloid leukemia in 12.3%, and acute lymphoblastic leukemia in 8.8%. Cognitive development at a median age of 10.7 years was within the normal range. In subgroup analyses of children in early childhood, the gestational age at birth was correlated with the cognitive outcome at a median age of 1.7 years. Scores for language development, intelligence, attention, memory and behavior, as well as clinical neurological and general pediatric examinations were within normal ranges. In subgroup analyses, the need for supportive care in the child was associated with the loss of the mother. Prenatal exposure to hematological maternal malignancies with or without treatment did not affect the neurodevelopment of the child in the long term. Yet, caution is indicated and surveillance of the emotional development of the child is needed, especially when the mother is deceased to cancer.

Executive functioning in 6 year old children exposed to chemotherapy in utero.

BACKGROUND: Cancer treatment during pregnancy imposes a dilemma. Maternal advantage should be weighed against the potential impact of chemotherapy on child development. Recent studies in cancer survivors have shown that exposure to chemotherapeutic agents can have late adverse effects on cognitive functioning and executive functioning (EF). It is still unclear whether these late adverse effects also arise if a child is exposed to chemotherapy in utero. AIM: To compare the development of executive functioning in 6 year old children prenatally exposed to chemotherapy (study group) and children born to healthy women after an uncomplicated pregnancy (control group). METHODS AND STUDY DESIGN: In a multicenter cohort study, the outcome on a measure of EF was compared. Study and control children were prospectively examined by means of the Behavior Rating Inventory of Executive Function (BRIEF), a health questionnaire and an intelligence test. RESULTS: In total 37 study children and 37 matched controls were included. In the study group, 11 children (29.7%) were exposed to chemotherapy alone, 22 children (59.5%) were exposed to chemotherapy and surgery and 4 children (10.8%) were exposed to chemotherapy, surgery and radiotherapy during pregnancy. All outcome scales of the BRIEF were within normal ranges. However, a significant between-group difference in emotional control was found. CONCLUSION: Overall outcomes of EF were reassuring. However, children prenatally exposed to chemotherapy have weaker emotion regulation skills compared to their matched controls. The results underscore the need for long-term follow-up of these children.

Long-term efficacy of clinical hunger provocation to wean feeding tube dependent children.

BACKGROUND & AIMS: The incidence of tube feeding dependency seems to increase worldwide, and these children may remain on prolonged tube feeding for many months to years. The multidisciplinary clinical hunger provocation (CHP) program is an intensive inpatient intervention of usually 2-3 weeks, aimed at weaning children from tube feeding. CHP has been proven highly effective on the short term (80-86%), particularly when applied before the age of two years but long-term data are lacking. The aims of our study were to determine the long-term efficacy of the CHP program and factors associated with success or failure and to assess anthropometrics, feeding behavior, and medical outcomes at long-term follow-up. METHODS: All tube-dependent children who underwent CHP at a tertiary hospital in Amsterdam, the Netherlands, between 2001 and 2014, and had a minimum follow-up of 12-months in 2015, were eligible to participate in this retrospective cohort study. During the CHP program, tube feeding is ceased stepwise to create appetite, according to a strict protocol. The program was defined successful if patients achieved oral intake and could be fully weaned from tube feeding following the CHP program. Acute malnourishment was defined as weight for height <2 SD or loss of >1 SD within 3 months, chronic malnourishment as height for age <2 SD and both acute and chronic malnourishment as both a height for age and weight for height <2 SD. Long-term efficacy (tube free at varying follow-up periods), anthropometrics (height for age, weight for height), feeding behavior and medical outcomes were assessed by a structured cross-sectional parental interview. RESULTS: In total, 57 patients were admitted to the CHP program. Fifty-two patients could be contacted of whom 42 participated in the study (response rate 81%) with a median age at admittance of 19 (IQR 13-22) months (62% female). The program was initially successful in 36/42 (86% (Bca CI 95% 75.0-95.2)) patients. A younger age upon initiation of tube feeding was negatively correlated with success (p 0.016). At follow-up, a median period of 67.0 (IQR 37.0-101.5) months after discharge, long-term efficacy was 32/41 (78% (Bca CI 95% 64.1-90.0)) (1 missing data). Patients with a successful CHP had beneficial outcomes compared to those with an unsuccessful CHP, showing less selective eating behavior (p 0.025), nocturnal feeding (p 0.044), forced feeding (p 0.044) and hospital admissions (p 0.028). However, 44% of successfully weaned patients fulfilled the criteria for malnourishment at long-term follow-up (13% acute, 22% chronic, and 9% both acute and chronic (compared to 22% at admittance: 13% acute, 6% chronic, and 3% both)). 59.4% of successfully weaned patients showed signs of developmental delays or were diagnosed with new medical diagnoses (43.8%) at long-term follow-up. CONCLUSIONS: The multidisciplinary CHP is a highly effective short-term (86%) and long-term (78%) intervention to wean young children from tube feeding, with beneficial feeding outcomes. However, at long-term follow-up, many successfully weaned patients were malnourished, showed signs of developmental delay, and were diagnosed with new medical diagnoses. For these reasons, patients should be monitored carefully during and after tube weaning, also after successful CHP. Tube dependency might be an early expression of medical diagnoses.

Longitudinal development of cancer-related fatigue and physical activity in childhood cancer patients.

PURPOSE: Cancer-related fatigue is one of the most distressing side effects of childhood cancer treatment. Physical activity can decrease fatigue and has positive effects on other health outcomes. Most research on physical activity pertains to adults, and the few studies that focus on children have limited follow-up time. This study evaluates cancer-related fatigue in children and its association with physical activity over a one-year time period. METHODS: Sixty-eight children with cancer (7-18 years) were recruited during or within the first year after treatment. Physical activity (Actical activity monitor) and cancer-related fatigue (Pediatric Quality-of-Life Questionnaire Multidimensional Fatigue Scale (PedsQL-MFS), self- and parent- reports) were assessed at baseline, 4 months, and 12 months. PedsQL-MFS scores were compared with Dutch norms. Longitudinal association of cancer-related fatigue with physical activity was evaluated (No. NTR 1531). RESULTS: Generally, PedsQL-MFS scores were worse than norms at baseline and 4 months, and recovered by 12 months except for the parent-proxy scores in adolescents. Younger children (≤12 years) self-reported comparable or better scores than norms. Physical activity generally improved over time, but patients mostly remained sedentary. During follow-up, increased physical activity was associated with less cancer-related fatigue. CONCLUSION: Cancer-related fatigue in children improves over time, and increased physical activity is associated with less cancer-related fatigue. Given the sedentary lifestyle of this population, the positive effect of physical activity on cancer-related fatigue, and the many other health benefits of an active lifestyle, it is important to stimulate physical activity in childhood cancer patients and survivors.

Effects of a combined physical and psychosocial training for children with cancer: a randomized controlled trial.

BACKGROUND: Physical fitness and psychosocial function is often reduced in children during or shortly after cancer treatment. This study evaluates the effect of a combined physical exercise and psychosocial intervention on cardiorespiratory fitness, muscle strength, body composition, psychosocial function and health-related quality of life (HrQoL). In addition, intervention mediators, applicability and adherence were examined. METHODS: This multicenter randomized controlled trial included 68 children with cancer [mean age 13.2 (SD: 3.1) years; 54% male] during treatment or within 12-months post-treatment. The 12-week intervention consisted of 24 individual physical exercise sessions supervised by a physiotherapist, and 6 psychosocial training sessions for children and 2 for parents. Physical fitness and psychosocial function were assessed at baseline, directly post-intervention and at 12 months' post-baseline. Generalized estimating equations were used to simultaneously assess intervention effects at short and long-term. Additionally, we evaluated within-group differences over time. Potential physical and psychosocial mediators in the intervention effect on HrQoL were examined using the product-of-coefficient test. Applicability and adherence were assessed by trainer-report. RESULTS: This study was able to compare 26 children who received the study intervention, with 33 children who received usual care. No significant differences in the effects of the intervention were found on physical fitness and psychosocial function at short-term. At 12-months follow-up, significantly larger improvements in lower body muscle strength (ß = 56.5 Newton; 95% CI: 8.5; 104.5) were found in the intervention group when compared to the control group. Within-group changes showed significant improvements over time in HrQoL and bone density in both groups. Intervention effects on HrQoL were not significantly mediated by physical fitness and psychological function. Intervention applicability was satisfactory with an average session attendance of 67% and 22% dropout (mainly due to disease recurrence). CONCLUSIONS: This 12-week physical exercise and psychosocial training intervention for children with cancer was applicable and showed satisfactory adherence. We found no significant between-group differences in effect, except for a significant improvement in lower body muscle strength at long-term in the intervention group compared to the control group. Yet, both the intervention and the control group showed improvements in bone mineral density and HrQoL over time. TRIAL REGISTRATION: The trial was registered at the Dutch Trial Registry ( NTR1531 ). Registered 12 November 2008.

Attention deficit hyperactivity disorder and autism spectrum disorder symptoms in school-age children born very preterm.

BACKGROUND: Very preterm (VP) children face a broad range of neurodevelopmental sequelae, including behavioral problems. AIM: To investigate prevalence, pervasiveness and co-occurrence of symptoms of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in school-age children born very preterm. METHODS: Using questionnaire and diagnostic interview data, parent and teacher reported symptoms of ADHD and ASD of 57 VP-children (mean age = 9.2 years) were compared with 57 gender and age matched full-term children using t-tests. Intra-class correlation coefficients quantified parent-teacher agreement. Correlation analysis investigated co-occurrence of ADHD/ASD symptoms. ADHD/ASD measures were aggregated using principal component analysis. Regression analyses investigated the contribution of perinatal risk factors, sex and SES to ADHD/ASD symptoms. RESULTS: VP-children showed higher levels of parent and teacher reported attention problems, social impairment and compromised communication skills. Fair to strong agreement was found between parent and teacher reported ADHD and ASD symptoms, indicating pervasiveness of observed difficulties. Co-occurrence of ADHD and ASD symptoms in VP-children was found. Lower gestational age was associated with higher ADHD and ASD symptom levels, male sex with higher ADHD symptom levels and lower SES with higher ASD symptom levels. CONCLUSION: School-age VP-children show higher levels of ADHD and ASD symptoms, and attention, socialization and communication difficulties in particular. Routinely screening for these problems is recommended in follow-up care.

First experience with electronic feedback of the Psychosocial Assessment Tool in pediatric cancer care.

PURPOSE: The Psychosocial Assessment Tool (PAT) is a brief family screener, identifying families at universal or elevated risk for psychosocial problems. This study aimed to determine the feasibility and usability of the electronic PAT (ePAT) in pediatric cancer care. METHODS: Eighty-six parents of newly diagnosed children with cancer (0-18 years) agreed to participate and registered at the website www.hetklikt.nu (58%). Seventy-five families completed the ePAT at approximately 1 month post-diagnosis. Answers were transformed into an electronic PROfile (PAT ePROfile) and fed back to the psychosocial team. Team members completed a semi-structured evaluation questionnaire. Feasibility was measured as the percentage of website registrations, completed ePATs, and PAT ePROfiles reviewed or discussed by the team. Usability included perceived match of the PAT ePROfile with the team's own risk estimation, perceived added value, and perceived actions undertaken as a result of the PAT ePROfile. RESULTS: Feasibility was 70% for website registration, 87% for completed ePATs, 85% for PAT ePROfile reviewing, and 67% for ePROfile discussion. Team members reported that the PAT ePROfile matched with their own risk estimation (M = 7.92, SD = 1.88) and did not provide additional information (M = 2.18, SD = 2.30). According to the team, actions were undertaken for 25% of the families as a result of the PAT ePROfile. More actions were undertaken for families with elevated risk scores compared to universal risk scores (p = .007). CONCLUSIONS: Implementation of the ePAT seems generally feasible, but it is not always clear how this screener adds to current clinical practice. Strategies should be developed together with team members to improve quick exchange of ePAT results and allocate care according to the needs of the families.

Cardiorespiratory fitness and physical activity in children with cancer.

PURPOSE: This study assessed cardiorespiratory fitness (CRF), physical activity (PA), and sedentary behavior (SB), as well as factors associated with these outcomes in children during or shortly after cancer treatment. METHODS: Cross-sectionally, CRF data, obtained by the cardiopulmonary exercise test, and PA and SB data, obtained by an accelerometer, were assessed in children with cancer (8-18 years old). Linear regression models were used to determine associations between CRF, PA, or SB and patient characteristics. RESULTS: Among 60 children with cancer, mean age 12.6 years, 35 boys, 28 % were during cancer treatment. CRF, reported as the z score of VO2peak, showed that 32 children had a VO2peak z score which was -2 below the predicted value. CRF was significantly associated with PA and SB: each additional activity count per minute resulted in 0.05 ml/kg/min VO2peak increase and each additional minute sedentary reduced VO2peak by 0.06 ml/kg/min. Multiple linear regression models of PA and SB showed that decreased activity was significantly associated with higher age, being fatigued, being during childhood cancer treatment (p < 0.001), or having a higher percentage of fat mass. The multiple linear regression model showed that lower CRF was significantly associated with increased fatigue, being during cancer treatment, having a higher percentage of fat mass, and lower belief of own athletic competence (p < 0.001). CONCLUSION: This study revealed that children during or shortly after cancer treatment have low CRF scores. The most inactive children had a higher fat mass, were fatigued, older, and during childhood cancer treatment. Unexpectedly, treatment-related factors showed no significant association with activity behavior.

Effects of a combined physical and psychosocial intervention program for childhood cancer patients on quality of life and psychosocial functioning: results of the QLIM randomized clinical trial.

OBJECTIVE: Although survival rates in childhood cancer have improved, prevention and reduction of late effects remain important. This study evaluates the effects of a combined physical exercise and psychosocial intervention on health-related quality of life (HrQoL) and psychosocial functioning in childhood cancer patients. METHODS: In this multicenter randomized controlled trial, cancer patients (aged 8-18 years) and their parents filled in questionnaires on HrQoL, depressive symptoms, behavioral problems, and self-esteem. Measurements were conducted at baseline, shortly after the 12-week intervention period and 12 months after baseline. Generalized estimating equations analyses were performed to assess short-term and long-term psychosocial effects. RESULTS: Of the 174 eligible patients, 68 (39.1%) participated. The intervention group consisted of 30 participants at baseline [mean age 13.0 (SD 3.0) years; 53% male], 26 at short-term and 22 at long-term follow-up. The 'care as usual' control group consisted of 38 participants at baseline [mean age 12.6 (SD 3.1) years; 53% male], 33 at short-term and 31 at long-term follow-up. Overall, the intervention did not improve psychosocial functioning and HrQoL. According to parent-proxy reports, the intervention leads to a greater improvement on pain-related HrQoL on both the short (ß = 13.4; 95% CI: 3.0; 23.8) and long term (ß = 13.0; 95% CI: 1.6; 24.4) and to greater improvement on procedural anxiety immediately after the intervention (ß = 12.6; 95% CI: 1.9; 23.3). CONCLUSION: A combined physical and psychosocial training for children with cancer did not have effects on HrQoL or psychosocial functioning, with exception of modest positive effects on parent-reported pain and procedural anxiety Copyright © 2015 John Wiley & Sons, Ltd.

Clinical tube weaning supported by hunger provocation in fully-tube-fed children.

BACKGROUND: Children with congenital malformations, mental retardation, and complex early medical history frequently have feeding problems. Although tube feeding is effective in providing the necessary energy and nutrients, it decreases the child's motivation to eat and may lead to oral aversion. In this study, we sought to confirm our previous results, showing that a multidisciplinary clinical hunger provocation program may lead to quick resumption of oral feeding. METHODS: In a crossover study, 22 children of 9 to 24 months of age who were fully dependent on tube feeding were randomly assigned to one of two groups: group A, intervention group (2-week multidisciplinary clinical hunger provocation program); and group B, control group (4-week outpatient treatment by the same multidisciplinary team). Patients failing one treatment were reassigned to the other treatment group. Primary outcome measures were at least 75% orally fed at the conclusion of the intervention and fully orally fed and gaining weight 6 months after the intervention. RESULTS: In group A, 9/11 patients were successfully weaned from tube feeding (2 failures: 1 developed ulcerative colitis, 1 drop-out). In group B, only 1 patient was weaned successfully; 10/11 were reassigned to the clinical hunger provocation program, all being weaned successfully. Six months after the intervention, 1 patient had to resume tube feeding. In total, in the control group, 1/11 (9%) was weaned successfully as compared with 18/21 (86%) in the hunger provocation group (P < 0.001). CONCLUSIONS: Multidisciplinary clinical hunger provocation is an effective short-term intervention for weaning young children from tube feeding.

Applicability and evaluation of a psychosocial intervention program for childhood cancer patients.

PURPOSE: The purpose of this study is to explore the applicability of a psychosocial intervention in childhood cancer patients. METHODS: This individualized structured psychosocial program to enhance social-emotional functioning and coping with disease-related effects includes six sessions for children and two sessions for parents. This program was part of a combined intervention with physical exercise. Questionnaires are used to evaluate completion of the psychosocial intervention, coping and satisfaction with the psychosocial intervention by patients and psychologists, and ranking of the individual topics by patients, parents, and psychologists. RESULTS: Of the 30 patients (mean age 13.0 (SD 3.0); 53.3 % male; 30 % still on treatment) who participated in the psychosocial intervention, two dropped out due to medical complications and one due to lack of time; 90 % completed the psychosocial intervention. Overall, patients liked participation in the intervention (4.2 on a 5-point scale; SD 0.8) and were positive about the psychologists (8.1 on a 10-point scale; SD 1.3). Psychologists rated the intervention on several points (e.g., clarity of the manual and content of the intervention), and mean scores ranged from 7.1 (SD 1.1) to 8.6 (SD 0.9) on 10-point scales. Minor adaptations were suggested by patients and psychologists, including customizing according to age and a more patient-tailored approach. CONCLUSION: This psychosocial intervention for childhood cancer patients appears to be applicable. Future studies need to establish whether this intervention combined with a physical exercise intervention actually improves psychosocial functioning of childhood cancer patients. When proven effective, this combined intervention can be offered to childhood cancer patients and may enhance their physical health and quality of life.

Factors influencing childhood cancer patients to participate in a combined physical and psychosocial intervention program: Quality of Life in Motion.

BACKGROUND: For a multi-center randomized trial investigating the effects of a 12-week physical and psychosocial intervention program for children with cancer, we invited 174 patients (8-18 years old) on treatment or within 1 year after treatment; about 40% participated. Reasons for non-participation were investigated. METHODS: Eligible patients received written and verbal information about the study. Those declining to participate were asked to complete questionnaires concerning: reasons for non-participation, daily physical activity, health-related quality of life (HrQoL), and behavioral problems. Participants completed the same questionnaires at baseline (excluding 'reasons for non-participation'). RESULTS: Of 174 eligible patients, 106 did not participate; of these, 61 (57.5%) completed the one-time survey. The main reasons for non-participation as reported by the parents were 'too time consuming' and 'participation is too demanding for my child', while children most frequently reported 'too time consuming' and 'already frequently engaged in sports'. No differences between participants and non-participants were found for age, HrQoL, parental-reported behavior problems, sport participation, school type, BMI, and perceived health. A greater distance from home to hospital resulted in reduced participation (ß: -0.02; p = 0.01). Non-participants rated their fitness level higher (p = 0.03). Participating children (11-18 years old) reported more behavioral problems (p = 0.02), in particular internalizing problems (p = 0.06). CONCLUSIONS: Participation of childhood cancer patients in an intensive physical and psychosocial intervention program seems related to the burden of the intervention and the travel distance from home to hospital. In general, non-participants rated their fitness level higher compared with participants. Patients with more (internalizing) behavioral problems seem more likely to participate in the study.
