Symptoms of anxiety and depression in patients with amyotrophic lateral sclerosis and their relatives during the disease trajectory.

OBJECTS: The aim of this study was to describe the presence of anxiety and depression among patients with Amyotrophic Lateral Sclerosis (ALS) and their relatives from diagnosis and during the disease progression. An additional aim was to explore if the patient's physical function correlated with the patients' or relatives' anxiety and depression. METHODS: A prospective and longitudinal study, including 33 patients with ALS and their relatives who filled out the Hospital Anxiety and Depression Scale (HADS) at the time of diagnosis and over a period of two years. The patient's physical function was measured with the revised Amyotrophic Lateral Sclerosis Functional and Rating Scale (ALS FRS-R). RESULTS: The results showed that many patients (45%) and relatives (58%) had symptoms of anxiety and that 13% of the patients and 29% of the relatives had symptoms of depression soon after the patient had been diagnosed with ALS. The prevalence of anxiety decreased over time in the group of patients but remained stable in the group of relatives. Relatives had more symptoms of anxiety compared to patients. There was a correlation between the patient's physical function and HADS in the group of relatives; however, no correlation was found in the group of patients. CONCLUSION: The results showed that many patients and relatives suffered from symptoms of anxiety quite soon after their diagnosis, and that many relatives had symptoms of anxiety during the disease trajectory. This highlights the need to continuously measure patients' anxiety/depression level but also to pay attention to symptoms among relatives.

A long-term follow-up of treatment for young children with obesity: a randomized controlled trial.

BACKGROUND: Early childhood obesity interventions supporting parents have the largest effects on child weight status. However, long-term follow-ups are lacking. OBJECTIVE: To examine weight status 48 months after obesity treatment initiation for 4- to 6-year-olds. METHODS: 177 families were recruited to the More and Less study, a 12-month randomized controlled trial (RCT) conducted in Sweden (2012-2017); 6 children were excluded due to medical diagnoses. Thus, 171 families (non-Swedish origin 59%, university degree 40%) were eligible for this 48-month follow-up with modified intention-to-treat (n = 114 had 48-month data, n = 34 dropped out, n = 23 lost to follow-up). The RCT compared 3 treatment approaches: a 10-week parent support program (1.5 h/w) with follow-up booster sessions (PGB) or without (PGNB), and standard outpatient treatment (ST). Treatment effects on primary outcome (BMI-SDS) and secondary outcomes (BMI, %IOTF25 i.e., the distance, in percent, above the cut-off for overweight) were assessed. Clinically significant reduction of BMI-SDS (≥0.5) was assessed with risk ratio. Sociodemographic factors and attendance were examined by three-way interactions. RESULTS: After 48 months (mean 50 months, range 38-67 months) mean (95% CI) BMI-SDS was reduced in all groups: PGB -0.45 (-0.18 to -0.73, p < 0.001), PGNB -0.34 (-0.13 to -0.55, p < 0.001), ST -0.25 (-0.10 to -0.40, p < 0.001), no significant difference between groups. A clinically significant reduction of BMI-SDS ≥ 0.5 was obtained in 53.7% of PGB which was twice as likely compared to ST, 33.0%, RR 2.03 (1.27 to 3.27, p = 0.003), with no difference to PGNB, 46.6% (p = 0.113). %IOTF25 was unchanged from baseline for PGB 4.50 (-1.64 to 10.63), and significantly lower compared to ST 11.92 (8.40 to 15.44) (p = 0.043). Sociodemographics or attendance had no effect. CONCLUSION: The intensive parent-support early childhood obesity intervention led to better weight status outcomes over time, though BMI-SDS alone did not reflect this. Further research should investigate how to assess weight changes in growing children. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov, NCT01792531 .

The Role of Long-Term Physical Activity in Relation to Cancer-Related Health Outcomes: A 12-Month Follow-up of the Phys-Can RCT.

PURPOSE: While moderate-to-vigorous intensity physical activity (MVPA) is associated with various health improvements shortly after completion of exercise interventions, it remains unclear which health benefits can be expected when MVPA levels are maintained in the long term in cancer survivors. We aimed to assess the associations of (1) MVPA level at 12-month follow-up and (2) long-term MVPA patterns (from immediately post-intervention to 12-month follow-up) with different cancer-related health outcomes. METHODS: In the Physical training and Cancer (Phys-Can) RCT, 577 participants diagnosed with breast (78%), prostate (19%), or colorectal (3%) cancer were randomized to 6 months of exercise during curative cancer treatment. Accelerometer-assessed physical activity and outcome data (ie, cancer-related fatigue, health-related quality of life [HRQoL], anxiety and depression, functioning in daily life, cardiorespiratory fitness, sedentary time and sleep) were collected immediately post-intervention and at 12-month follow-up. Based on the sample's median of MVPA immediately post-intervention (65 minutes/day) and the changes between the 2 measurement points, 4 categories with different long-term MVPA patterns were created: High & Increasing, High & Decreasing, Low & Increasing, and Low & Decreasing. Multiple linear regression analyses were performed for the analyses. RESULTS: A total of 353 participants were included in the analyses. At 12-month follow-up, a higher MVPA level was significantly associated with lower fatigue in 3 domains (general fatigue [ß = -.33], physical fatigue [ß = -.53] and reduced activity [ß = -.37]), higher cardiorespiratory fitness (ß = .34) and less sedentary time (ß = -.35). For long-term MVPA patterns, compared to the participants in the "Low & Decreasing" category, those in the "High & Increasing" category reported significantly lower fatigue in 3 domains (general fatigue [ß = -1.77], physical fatigue [ß = -3.36] and reduced activity [ß = -1.58]), higher HRQoL (ß = 6.84) and had less sedentary time (ß = -1.23). CONCLUSION: Our results suggest that long-term physical activity is essential for improving health outcomes post-intervention in cancer survivors. Cancer survivors, including those who reach recommended MVPA levels, should be encouraged to maintain or increase MVPA post-intervention for additional health benefits.

How many days of continuous physical activity monitoring reliably represent time in different intensities in cancer survivors.

BACKGROUND: Physical activity (PA) monitoring is applied in a growing number of studies within cancer research. However, no consensus exists on how many days PA should be monitored to obtain reliable estimates in the cancer population. The objective of the present study was to determine the minimum number of monitoring days required for reliable estimates of different PA intensities in cancer survivors when using a six-days protocol. Furthermore, reliability of monitoring days was assessed stratified on sex, age, cancer type, weight status, and educational level. METHODS: Data was obtained from two studies where PA was monitored for seven days using the SenseWear Armband Mini in a total of 984 cancer survivors diagnosed with breast, colorectal or prostate cancer. Participants with ≥22 hours monitor wear-time for six days were included in the reliability analysis (n = 736). The intra-class correlation coefficient (ICC) and the Spearman Brown prophecy formula were used to assess the reliability of different number of monitoring days. RESULTS: For time in light PA, two monitoring days resulted in reliable estimates (ICC >0.80). Participants with BMI ≥25, low-medium education, colorectal cancer, or age ≥60 years required one additional monitoring day. For moderate and moderate-to-vigorous PA, three monitoring days yielded reliable estimates. Participants with BMI ≥25 or breast cancer required one additional monitoring day. Vigorous PA showed the largest within subject variations and reliable estimates were not obtained for the sample as a whole. However, reliable estimates were obtained for breast cancer survivors (4 days), females, BMI ≥30, and age <60 years (6 days). CONCLUSION: Shorter monitoring periods may provide reliable estimates of PA levels in cancer survivors when monitored continuously with a wearable device. This could potentially lower the participant burden and allow for less exclusion of participants not adhering to longer protocols.

Cost-effectiveness of different exercise intensities during oncological treatment in the Phys-Can RCT.

BACKGROUND: Cost-effectiveness is important in the prioritisation between interventions in health care. Exercise is cost-effective compared to usual care during oncological treatment; however, the significance of exercise intensity to the cost-effectiveness is unclear. In the present study, we aimed to evaluate the long-term cost-effectiveness of the randomised controlled trial Phys-Can, a six-month exercise programme of high (HI) or low-to-moderate intensity (LMI) during (neo)adjuvant oncological treatment. METHODS: A cost-effectiveness analysis was performed, based on 189 participants with breast, colorectal, or prostate cancer (HI: n = 99 and LMI: n = 90) from the Phys-Can RCT in Sweden. Costs were estimated from a societal perspective, and included cost of the exercise intervention, health care utilisation and productivity loss. Health outcomes were assessed as quality-adjusted life-years (QALYs), using EQ-5D-5L at baseline, post intervention and 12 months after the completion of the intervention. RESULTS: At 12-month follow-up after the intervention, the total cost per participant did not differ significantly between HI (€27,314) and LMI exercise (€29,788). There was no significant difference in health outcome between the intensity groups. On average HI generated 1.190 QALYs and LMI 1.185 QALYs. The mean incremental cost-effectiveness ratio indicated that HI was cost effective compared with LMI, but the uncertainty was large. CONCLUSIONS: We conclude that HI and LMI exercise have similar costs and effects during oncological treatment. Hence, based on cost-effectiveness, we suggest that decision makers and clinicians can consider implementing both HI and LMI exercise programmes and recommend either intensity to the patients with cancer during oncological treatment to facilitate improvement of health.

Reallocating sedentary time to physical activity: effects on fatigue and quality of life in patients with breast cancer in the Phys-Can project.

PURPOSE: We aimed to investigate the effects of reallocating sedentary time to an equal amount of light (LPA) or moderate-to-vigorous intensity physical activity (MVPA) on cancer-related fatigue and health-related quality of life (HRQoL) in patients with breast cancer. We also aimed to determine the daily amount of sedentary time needed to be reallocated to LPA or MVPA to produce minimal clinically important changes in these outcomes. METHODS: Pooled baseline data from three studies were used, including women with breast cancer who participated in the Phys-Can project. Fatigue was assessed with the Multidimensional Fatigue Inventory questionnaire (MFI; five dimensions, 4-20 scale) and HRQoL with the European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30; 0-100 scale). Sedentary time and physical activity were measured with accelerometry. Isotemporal substitution modelling was used for the analyses. RESULTS: Overall, 436 participants (mean age 56 years, fatigue 11 [MFI], HRQoL 66 [EORTC QLQ-C30], LPA 254 min/day, MVPA 71 min/day) were included. Fatigue significantly decreased in two MFI dimensions when reallocating 30 min/day of sedentary time to LPA: reduced motivation and reduced activity (ß = - 0.21). Fatigue significantly decreased in three MFI dimensions when reallocating 30 min/day of sedentary time to MVPA: general fatigue (ß = - 0.34), physical fatigue (ß = - 0.47) and reduced activity (ß = - 0.48). To produce minimal clinically important changes in fatigue (- 2 points on MFI), the amount of sedentary time needed to be reallocated to LPA was ≈290 min/day and to MVPA was ≥ 125 min/day. No significant effects were observed on HRQoL when reallocating sedentary time to LPA or MVPA. CONCLUSIONS: Our results suggest that reallocating sedentary time to LPA or MVPA has beneficial effects on cancer-related fatigue in patients with breast cancer, with MVPA having the greatest impact. In relatively healthy and physically active breast cancer populations, a large amount of time reallocation is needed to produce clinically important changes. Future studies are warranted to evaluate such effects in broader cancer populations. TRIAL REGISTRATION: NCT02473003 (10/10/2014) and NCT04586517 (14/10/2020).

Does inflammation markers or treatment type moderate exercise intensity effects on changes in muscle strength in cancer survivors participating in a 6-month combined resistance- and endurance exercise program? Results from the Phys-Can trial.

BACKGROUND: Resistance exercise has a beneficial impact on physical function for patients receiving oncological treatment. However, there is an inter-individual variation in the response to exercise and the tolerability to high-intensity exercise. Identifying potential moderating factors, such as inflammation and treatment type, for changes in muscle strength is important to improve the effectiveness of exercise programs. Therefore, we aimed to investigate if inflammation and type of oncological treatment moderate the effects of exercise intensity (high vs. low-moderate) on muscular strength changes in patients with breast (BRCA) or prostate cancer (PRCA). METHODS: Participants with BRCA (n = 286) and PRCA (n = 65) from the Physical training and Cancer study (Phys-Can) were included in the present study. Participants performed a combined resistance- and endurance exercise program during six months, at either high or low-moderate intensity. Separate regression models were estimated for each cancer type, with and without interaction terms. Moderators included in the models were treatment type (i.e., neo/adjuvant chemotherapy-yes/no for BRCA, adjuvant androgen deprivation therapy (ADT)-yes/no for PRCA)), and inflammation (interleukin 6 (IL6) and tumor necrosis factor-alpha (TNFα)) at follow-up. RESULTS: For BRCA, neither IL6 (b = 2.469, 95% CI [- 7.614, 12.552]) nor TNFα (b = 0.036, 95% CI [- 6.345, 6.418]) levels moderated the effect of exercise intensity on muscle strength change. The same was observed for chemotherapy treatment (b = 4.893, 95% CI [- 2.938, 12.724]). Similarly, for PRCA, the effect of exercise intensity on muscle strength change was not moderated by IL6 (b = - 1.423, 95% CI [- 17.894, 15.048]) and TNFα (b = - 1.905, 95% CI [- 8.542, 4.732]) levels, nor by ADT (b = - 0.180, 95% CI [- 11.201, 10.841]). CONCLUSIONS: The effect of exercise intensity on muscle strength is not moderated by TNFα, IL6, neo/adjuvant chemotherapy, or ADT, and therefore cannot explain any intra-variation of training response regarding exercise intensity (e.g., strength gain) for BRCA or PRCA in this setting.

Pre-treatment levels of inflammatory markers and chemotherapy completion rates in patients with early-stage breast cancer.

BACKGROUND: Chemotherapy efficacy is largely dependent on treatment adherence, defined by the relative dose intensity (RDI). Identification of new modifiable risk factors associated with low RDI might improve chemotherapy delivery. Here, we evaluated the association between low RDI and pre-chemotherapy factors, including patient- and treatment-related characteristics and markers of inflammation. METHODS: This exploratory analysis assessed data from 267 patients with early-stage breast cancer scheduled to undergo (neo-)adjuvant chemotherapy included in the Physical training and Cancer (Phys-Can) trial. The association between low RDI, defined as < 85%, patient-related (age, body mass index, co-morbid condition, body surface area) and treatment-related factors (cancer stage, receptor status, chemotherapy duration, chemotherapy dose, granulocyte colony-stimulating factor) was investigated. Analyses further included the association between RDI and pre-chemotherapy levels of interleukin (IL)-6, IL-8, IL-10, C-reactive protein (CRP) and Tumor Necrosis Factor-alpha (TNF-α) in 172 patients with available blood samples. RESULTS: An RDI of < 85% occurred in 31 patients (12%). Univariable analysis revealed a significant association with a chemotherapy duration above 20 weeks (p < 0.001), chemotherapy dose (p = 0.006), pre-chemotherapy IL-8 (OR 1.61; 95% CI (1.01; 2.58); p = 0.040) and TNF-α (OR 2.2 (1.17; 4.53); p = 0.019). In multivariable analyses, inflammatory cytokines were significant association with low RDI for IL-8 (OR: 1.65 [0.99; 2.69]; p = 0.044) and TNF-α (OR 2.95 [1.41; 7.19]; p = 0.007). CONCLUSIONS: This exploratory analysis highlights the association of pre-chemotherapy IL-8 and TNF-α with low RDI of chemotherapy for breast cancer. IL-8 and TNF-α may therefore potentially help to identify patients at risk for experiencing dose reductions. Clinical trial number NCT02473003 (registration: June 16, 2015).

Effects of High and Low-To-Moderate Intensity Exercise During (Neo-) Adjuvant Chemotherapy on Muscle Cells, Cardiorespiratory Fitness, and Muscle Function in Women With Breast Cancer: Protocol for a Randomized Controlled Trial.

BACKGROUND: (Neo-)adjuvant chemotherapy for breast cancer is effective but has deleterious side effects on muscle tissue, resulting in reduced skeletal muscle mass, muscle function, and cardiorespiratory fitness. Various exercise regimens during cancer treatment have been shown to counteract some of these side effects. However, no study has compared the effect of high-intensity training versus low-to-moderate intensity training on muscle tissue cellular outcomes and physical function in patients with breast cancer during chemotherapy. OBJECTIVE: The aim of this substudy within the Physical Training in Cancer (Phys-Can) consortium is to evaluate and compare the effects of high and low-to-moderate intensity exercise on muscle cellular outcomes, muscle function, and cardiorespiratory fitness in women with breast cancer undergoing (neo-)adjuvant chemotherapy. We further aim to investigate if the effects of chemotherapy including taxanes on muscles will be different from those of taxane-free chemotherapy. METHODS: Eighty women recently diagnosed with breast cancer scheduled to start (neo-)adjuvant chemotherapy will be randomized to a combination of strength and endurance training, either at high intensity or at low-to-moderate intensity. Testing of muscle function and cardiorespiratory fitness and collection of muscle biopsies from the vastus lateralis muscle will be performed before the first cycle of chemotherapy (or after 1 week, when not possible) (T0), halfway through chemotherapy (T1), and after completion of chemotherapy (T2). It is estimated that approximately 50% of the participants will be willing to undergo muscle biopsies. To separate the effect of the treatment itself, a usual care group with no supervised training will also be included, and in this group, testing and collection of muscle biopsies will be performed at T0 and T2 only. RESULTS: This study is funded by Active Against Cancer (Aktiv mot kreft) (May 2013) and the Norwegian Cancer Society (December 2018). Inclusion started in December 2016 and the last participant is expected to be recruited in December 2022. As of June 2022, we enrolled 38 (19 with biopsies) participants to the high-intensity training group, 36 (19 with biopsies) participants to the low-to-moderate intensity training group, and 17 (16 with biopsies) participants to the usual care group. Data analyses will start in fall 2022. The first results are expected to be published in spring 2024. CONCLUSIONS: This study will generate new knowledge about the effects of different training intensities for women with breast cancer during chemotherapy treatment. It will give further insight into how chemotherapy affects the muscle tissue and how physical training at different intensities may counteract the treatment side effects in muscles. The results of this study will inform the development and refinement of exercise programs that are effective and compatible with the multidisciplinary management of breast cancer.

Patterns and determinants of adherence to resistance and endurance training during cancer treatment in the Phys-Can RCT.

BACKGROUND: Knowledge regarding adherence is necessary to improve the specificity of exercise interventions during cancer treatment. We aimed to determine adherence to resistance and endurance training interventions in parallel; identify subgroups with similar adherence characteristics; and examine determinants of these subgroups. METHODS: In the Phys-Can randomised controlled trial, participants (n = 577, 81% women, mean(SD) age 59(12) years, and 50% with BMI ≥ 25 kg/m2) starting (neo-) adjuvant treatment for breast, colorectal or prostate cancer were randomized to 6-month of high (HI) or low-to-moderate intensity (LMI) supervised, group-based resistance training and individual home-based endurance training, with or without behavior change support. Adherence was calculated as performed exercise volume as a proportion of prescribed exercise volume (0-100%), overall (HI and LMI groups) and for frequency, intensity, type and time (FITT principles) (HI group). Adherence to resistance training was plotted against adherence to endurance training overall and for each FITT principle. K-means cluster analysis was used to identify subgroups with similar adherence characteristics. Potential determinants of subgroup membership were examined using multinomial logistic regression. RESULTS: We found a positive curvilinear correlation between adherence to resistance and endurance training overall. A similar correlation was seen for adherence to frequency of resistance vs. endurance training in the HI group. In the HI group, adherence to resistance training intensity and time was > 80% for almost all participants. For endurance training adherence ranged from 0 to 100% for each of the FITT principles. Three clusters were identified, representing low, mixed, and high adherence to resistance and endurance training overall. Participants with higher age (Relative risk ratio [95% CI]; LMI: 0.86[0.77-0.96], HI: 0.83[0.74-0.93]), no behaviour change support (LMI: 0.11[0.02-0.56], HI: 0.20[0.05-0.85]), higher cardiorespiratory fitness (LMI: 0.81[0.69-0.94], HI: 0.80[0.69-0.92]), more fatigue (according to the reduced activity subscale of the MFI questionnaire) (LMI: 0.48[0.31-0.73], HI: 0.69[0.52-0.93]) or higher quality of life (LMI: 0.95[0.90-1.00], HI: 0.93[0.88-0.98]) were less likely to be in the low than the high adherence cluster whether randomised to LMI or HI training. Other determinants were specific to those randomised to LMI or HI training. CONCLUSIONS: In an exercise intervention during cancer treatment, adherence to resistance and endurance training were positively correlated. Personalisation of interventions and additional support for some subgroups of participants may improve adherence. Trial registration NCT02473003 (clinicaltrials.gov, Registered 16/06/2015).

Parents' experiences following conversations about their young child's weight in the primary health care setting: a study within the STOP project.

BACKGROUND: In primary healthcare, conversations between clinicians and parents about young children's overweight are key to providing support and initiating weight management. However, given the sensitivity of this topic, these conversations are difficult for both clinicians and parents and are sometimes delayed or avoided. To understand the emotional impact of these conversations, this study aims to shed light on parents' experiences following conversations with primary care nurses about their child's overweight. METHODS: Participants were recruited through a childhood obesity randomized controlled trial (RCT) conducted in Sweden. Telephone-based semi-structured interviews were conducted with 17 parents (mean age 40; the majority were women (n = 12/17), had a university degree (n = 14/17) and were born in Sweden (n = 13/16)). Their children were between 3 and 7 years old (mean age 4.8 years) with overweight (n = 7) or obesity (n = 10). The interviews were recorded, transcribed, and analyzed using thematic analysis. RESULTS: Two main themes were developed. Theme 1, 'Receiving the overweight/obesity diagnosis', explores parents' reactions to the conversation with the primary care nurse. Depending on how the nurse presented the topic, conversations either fostered an alliance between the parent and the nurse, encouraging parents to reflect and develop insights about the child's and the family's needs (subtheme Conversations that empower), or felt limited, uncomfortable, or belittling (subtheme Conversations that provoke resistance). Theme 2, 'Parenting a child with a formal diagnosis of obesity', explores challenges parents faced following the weight conversations, including managing their own feelings and concerns (subtheme Fear of transferring weight anxiety), dealing with others' reactions (subtheme Involve family and manage surroundings) and asking for and receiving support from health care professionals (subtheme Obtain support from health care professionals). CONCLUSIONS: While conversations with primary care nurses about children's weight were often emotional, most parents felt these conversations were ultimately helpful, as they encouraged them to enact positive lifestyle changes. Importantly, when nurses initiated conversations in a responsive, non-blaming way, inviting parents to reflect on their situation, parents felt more supported and empowered. These findings convey the importance of providing communication skills training to pediatric healthcare professionals, with particular focus on childhood overweight and obesity.

Exploring Moderators of the Effect of High vs. Low-to-Moderate Intensity Exercise on Cardiorespiratory Fitness During Breast Cancer Treatment - Analyses of a Subsample From the Phys-Can RCT.

Introduction: The results from the physical training and cancer randomized controlled trial (Phys-Can RCT) indicate that high intensity (HI) strength and endurance training during (neo-)adjuvant cancer treatment is more beneficial for cardiorespiratory fitness (CRF, measured as peak oxygen uptake [VO2peak]) than low-to-moderate intensity (LMI) exercise. Adherence to the exercise intervention and demographic or clinical characteristics of patients with breast cancer undergoing adjuvant treatment may moderate the exercise intervention effect on VO2peak. In this study, the objective was to investigate whether baseline values of VO2peak, body mass index (BMI), time spent in moderate- to vigorous-intensity physical activity (MVPA), physical fatigue, age, chemotherapy treatment, and the adherence to the endurance training moderated the effect of HI vs. LMI exercise on VO2peak. Materials and Methods: We used data collected from a subsample from the Phys-Can RCT; women who were diagnosed with breast cancer and had a valid baseline and post-intervention VO2peak test were included (n = 255). The exercise interventions from the RCT included strength and endurance training at either LMI, which was continuous endurance training at 40-50% of heart rate reserve (HRR), or at HI, which was interval training at 80-90% of HRR, with similar exercise volume in the two groups. Linear regression analyses were used to investigate moderating effects using a significance level of p < 0.10. Statistically significant interactions were examined further using the Johnson-Neyman (J-N) technique and regions of significance (for continuous variables) or box plots with adjusted means of post-intervention VO2peak (for binary variables). Results: Age, as a continuous variable, and adherence, dichotomized into < or > 58% based on median, moderated the effect of HI vs. LMI on CRF (B = -0.08, 95% CI [-0.16, 0.01], p interaction = 0.06, and B = 1.63, 95% CI [-0.12, 3.38], p interaction = 0.07, respectively). The J-N technique and regions of significance indicated that the intervention effect (HI vs. LMI) was positive and statistically significant in participants aged 61 years or older. Baseline measurement of CRF, MVPA, BMI, physical fatigue, and chemotherapy treatment did not significantly moderate the intervention effect on CRF. Conclusion: Women with breast cancer who are older and who have higher adherence to the exercise regimen may have larger effects of HI exercise during (neo-)adjuvant cancer treatment on CRF.

Children's experiences of meals after obesity treatment: a qualitative follow-up four years after a randomized controlled trial.

BACKGROUND: The practice of eating together, commensality, is rarely explored in the context of childhood obesity treatment. This is noteworthy given long-standing debates about the physical, psychosocial, and societal benefits of meals, especially family meals. Moreover, as children with obesity experience weight bias and stigma both within and outside the home, it is important to examine meals as a locus of social exchange around food and the body. Our study is based on the premises that eating together (i) matters and (ii) occurs in different environments with diverse social organization, where food-related interactions create varying arrangements of individuals, groups, their statuses, and their actions. METHOD: The study explores children's experiences of meals in different social contexts. Thirty-two children (age 8-10 years) living in Sweden were interviewed, 4 years after they entered an obesity intervention trial. Thematic analysis was applied to the data. RESULTS: We thematized three meal types, with each meal type having two subthemes: (i) "The family meal", with "Shared routines, rituals, and rules" and "Individual solutions and choices"; (ii) "The school meal", with "Rules and norms of the school" and "Strategies of the child"; and (iii) "The friend meal", with "Handling food that was disliked" and "Enjoyment of food". These three different meal types carried different experiences of and knowledge about how they were socially organized. CONCLUSIONS: While the children spoke about the family and school meals as meaningful, the friend meal stood out as particularly positive. Contrary to our expectations, the children did not express experiences of weight bias or obesity stigma around meals, nor did they speak negatively about parental control of their food intake. Our findings, especially regarding the friend meal, have implications for further research into commensality and social influences on eating among children with obesity, from early childhood into adolescence.

Long-term resource utilisation and associated costs of exercise during (neo)adjuvant oncological treatment: the Phys-Can project.

BACKGROUND: Exercise during oncological treatment is beneficial to patient health and can counteract the side effects of treatment. Knowledge of the societal costs associated with an exercise intervention, however, is limited. The aims of the present study were to evaluate the long-term resource utilisation and societal costs of an exercise intervention conducted during (neo)adjuvant oncological treatment in a randomised control trial (RCT) versus usual care (UC), and to compare high-intensity (HI) versus low-to-moderate intensity (LMI) exercise in the RCT. METHODS: We used data from the Physical Training and Cancer (Phys-Can) project. In the RCT, 577 participants were randomised to HI or to LMI of combined endurance and resistance training for 6 months, during oncological treatment. The project also included 89 participants with UC in a longitudinal observational study. We measured at baseline and after 18 months. Resource utilisation and costs of the exercise intervention, health care, and productivity loss were compared using analyses of covariance (RCT vs. UC) and t test (HI vs. LMI). RESULTS: Complete data were available for 619 participants (RCT HI: n = 269, LMI: n = 265, and UC: n = 85). We found no difference in total societal costs between the exercise intervention groups in the RCT and UC. However, participants in the RCT had lower rates of disability pension days (p < .001), corresponding costs (p = .001), and pharmacy costs (p = .018) than the UC group. Nor did we find differences in resource utilisation or costs between HI and LMI exercise int the RCT. CONCLUSION: Our study showed no difference in total societal costs between the comprehensive exercise intervention and UC or between the exercise intensities. This suggests that exercise, with its well-documented health benefits during oncological treatment, produces neither additional costs nor savings.

Short- and long-term effect of high versus low-to-moderate intensity exercise to optimise health-related quality of life after oncological treatment-results from the Phys-Can project.

PURPOSE: This study aimed to evaluate the effect of high intensity (HI) vs low-to-moderate intensity (LMI) exercise on health-related quality of life (HRQoL) up to 18 months after commencement of oncological treatment in patients with breast, colorectal or prostate cancer. In addition, we conducted a comparison with usual care (UC). METHODS: Patients scheduled for (neo)adjuvant oncological treatment (n = 577) were randomly assigned to 6 months of combined resistance and endurance training of HI or LMI. A longitudinal descriptive study (UC) included participants (n = 89) immediately before the RCT started. HRQoL was assessed by EORTC QLQ-C30 at baseline, 3, 6 and 18 months (1 year after completed exercise intervention) follow-up. Linear mixed models were used to study the groups over time. RESULTS: Directly after the intervention, HI scored significant (P = 0.02), but not clinically relevant, higher pain compared with LMI. No other significant difference in HRQoL was found between the exercise intensities over time. Clinically meaningful improvements in HRQoL over time were detected within both exercise intensities. We found favourable significant differences in HRQoL in both exercise intensities compared with UC over time. CONCLUSION: This study adds to the strong evidence of positive effect of exercise and shows that exercise, regardless of intensity, can have beneficial effects on HRQoL during oncological treatment and also for a substantial time after completion of an exercise intervention. In this study, for one year after. IMPLICATIONS FOR CANCER SURVIVORS: Patients can be advised to exercise at either intensity level according to their personal preferences, and still benefit from both short-term and long-term improvements in HRQoL.

The Phys-Can study: meaningful and challenging - supervising physical exercise in a community-based setting for persons undergoing curative oncological treatment.

Introduction: Supervised exercise may improve physical function and quality of life during oncological treatment. Providing supervised exercise to all patients at hospitals may be impractical, with community-based settings (e.g. public gyms) as a possible alternative. To facilitate implementation, knowledge about the experiences of professionals who deliver exercise programs in community-based settings is crucial.Objective: To explore how physical therapists and personal trainers experience supervising exercise in a community-based setting for persons undergoing curative oncological treatment. Methods: Nine physical therapists and two personal trainers (coaches) were interviewed individually. The semi-structured interviews lasted 33-67 minutes and were analyzed using thematic analysis. Results: Two main themes emerged: "A meaningful task" and "A challenging task," with nine sub-themes. The coaches experienced supervising exercise for persons undergoing treatment as meaningful, as they became a link between oncology care and health promotion. They grew more confident in the role and ascertained that exercising during treatment was feasible. Challenges included managing side effects of treatment and contradictory information from oncology care staff at hospitals, advising patients not to exercise.Conclusion: Supervising exercise for persons undergoing oncological treatment in a community-based setting may be highly rewarding for professionals who deliver exercise programs, which is promising for implementation. However, patients receive contradictory information about exercise, which may prevent physical activity. Also, supervising exercise for persons undergoing oncological treatment requires skills training; this is suggested for inclusion in educational programs for physical therapists and others. Future research should focus on strategies for cooperation between oncology care and health promotion.

Who makes it all the way? Participants vs. decliners, and completers vs. drop-outs, in a 6-month exercise trial during cancer treatment. Results from the Phys-Can RCT.

PURPOSE: To compare sociodemographic, health- and exercise-related characteristics of participants vs. decliners, and completers vs. drop-outs, in an exercise intervention trial during cancer treatment. METHODS: Patients with newly diagnosed breast, prostate, or colorectal cancer were invited to participate in a 6-month exercise intervention. Background data for all respondents (n = 2051) were collected at baseline by questionnaire and medical records. Additional data were collected using an extended questionnaire, physical activity monitors, and fitness testing for trial participants (n = 577). Moreover, a sub-group of decliners (n = 436) consented to additional data collection by an extended questionnaire . Data were analyzed for between-group differences using independent t-tests and chi2-tests. RESULTS: Trial participants were younger (59 ± 12yrs vs. 64 ± 11yrs, p < .001), more likely to be women (80% vs. 75%, p = .012), and scheduled for chemotherapy treatment (54% vs. 34%, p < .001), compared to decliners (n = 1391). A greater proportion had university education (60% vs 40%, p < .001), reported higher anxiety and fatigue, higher exercise self-efficacy and outcome expectations, and less kinesiophobia at baseline compared to decliners. A greater proportion of trial participants were classified as 'not physically active' at baseline; however, within the group who participated, being "physically active" at baseline was associated with trial completion. Completers (n = 410) also reported less kinesiophobia than drop-outs (n = 167). CONCLUSION: The recruitment procedures used in comprehensive oncology exercise trials should specifically address barriers for participation among men, patients without university education and older patients. Individualized efforts should be made to enroll patients with low exercise self-efficacy and low outcome expectations of exercise. To retain participants in an ongoing exercise intervention, extra support may be needed for patients with kinesiophobia and those lacking health-enhancing exercise habits at baseline.

Quality of life among relatives of patients with amyotrophic lateral sclerosis: A prospective and longitudinal study.

OBJECTIVE: Relatives are often central in caring for patients with amyotrophic lateral sclerosis (ALS), involving considerable physical, emotional, and social challenges. The aim of this study was to describe individual quality of life (iQoL) among relatives of patients with ALS, from diagnosis through disease progression. METHOD: A total of 31 relatives were included. Data collection was performed at five time points: 1-3 months after their relatives had been diagnosed with ALS and every 6 months for 2 years. Quality of life was determined using the Schedule of Evaluation of Individual Quality of Life - Direct Weighting (SEIQoL-DW), emotional distress with the Hospital Anxiety and Depression Scale (HADS), and the illness severity of the patients was determined with the Amyotrophic Lateral Sclerosis Functional Rating Scale (ALS FRS-R). RESULTS: The SEIQoL-DW involves participants nominating the important life areas. The most nominated areas were family, friends, health, and leisure. Although most relatives had overall good and stable iQoL, several had scores indicating poor iQoL on some occasions during the disease trajectory. The relatives' iQoL correlated with emotional well-being and the patient's physical function at different time points. SIGNIFICANT OF RESULT: Social relations, emotional well-being, and rapid decline in the patient's physical function influence the relatives' iQoL. Measuring both emotional well-being and iQoL, with a focus on the relatives' own descriptions of perceived iQoL and those factors contributing to their iQoL during the disease trajectory may improve the possibility of identifying and supporting those relatives with poor iQoL.

How Do Interpersonal Relationships Affect Children's Weight Management? A Qualitative Analysis of Parents' Long-Term Perceptions after Obesity Treatment.

Background: Childhood obesity interventions are particularly effective during the preschool age, but little is known about parents' long-term perceptions of weight management. This study explores how parents perceive the influence of interpersonal relationships on their children's eating and physical activity 4 years after participating in a randomized controlled trial. Bronfenbrenner's ecological systems theory frames this study, with the child's environment conceptualized as interlocking microsystems that affect weight management. Methods: Interviews were conducted with 33 parents (85% mothers, 48% with university degree) of 33 children [mean age 9.3 (standard deviation 0.7), 46% girls] from Stockholm, Sweden. Interviews were analyzed using thematic analysis, focusing on parents' perceptions of interpersonal relationships: family, relatives, other children, preschool/school staff, and health care practitioners. Results: Two main themes were developed: (1) Discouragement, with the subthemes Conflicting rules and Social comparison, and (2) Support and understanding, with the subthemes Teamwork and Shared responsibility and continuity of care. Parents perceived children's weight management as a continuous orchestration of different influences across social spheres. Years after obesity treatment, parents struggled to maintain the child's healthy routines outside the home. However, when siblings, grandparents, teachers, and friends' parents acted supportively, routines were easier to maintain. Conclusions: The findings suggest that each microsystem in a child's environment has important influence on weight management, such that, as children grow older, children's lifestyles cannot be managed by parents alone. To facilitate weight management, more people in the child's environment should be involved early in the treatment process, and continued professional support should be offered to parents.

Changing the Home Food Environment: Parents' Perspectives Four Years after Starting Obesity Treatment for Their Preschool Aged Child.

Changing the home food environment is key to childhood obesity treatment. However, new challenges arise as the child grows older. This study investigates parents' views on the longer-term management of the home food environment, 4 years after starting obesity treatment for their preschool-aged child. Semi-structured interviews were conducted with 33 parents (85% mothers, 48% with a university degree) of 33 children (mean age 9.3 (SD 0.7), 46% girls) from Sweden. The interviews were analyzed using thematic analysis. Two main themes were developed. Making changes in the home food environment illustrates the types of changes families make over time in relation to child development. It consists of three subthemes: covert changes, overt changes and child-directed changes. The second theme, an ongoing negotiation, captures parents' experiences of managing the home food environment as a continuous process of balancing and recalibrating in relation to present challenges and concerns about the future. It includes three subthemes: concern and care, two steps forward one back and maintaining everyday balance. Managing the home food environment is a constant process affected by everyday life, parents' strategies and the child's development. Our findings can strengthen childhood obesity treatment and help prepare parents for challenges that lie ahead.
