Study Protocol of the Exercise Study: Unraveling Limitations for Physical Activity in Children With Chronic Diseases Order to Target Them With Tailored Interventions—A Randomized Cross Over Trial

Introduction: Physical activity is associated with many physiological and psychological health benefits across the lifespan. Children with a chronic disease often have lower levels of daily physical activity, and a decreased exercise capacity compared to healthy peers. In order to learn more about limitations for physical activity, we investigate children with four different chronic diseases: children with a Fontan circulation, children with Broncho Pulmonary Dysplasia (BPD), Pompe disease and inflammatory bowel disease (IBD). Each of these diseases is likely to interfere with physical activity in a different way. Knowing the specific limitations for physical activity would make it possible to target these, and increase physical activity by a personalized intervention. The aim of this study is to first investigate limitations for physical activity in children with various chronic diseases. Secondly, to measure the effects of a tailored exercise intervention, possibly including a personalized dietary advice and/or psychological counseling, on exercise capacity, endurance, quality of life, fatigue, fear for exercise, safety, muscle strength, physical activity levels, energy balance, and body composition.Methods and Analysis: This randomized crossover trial will aim to include 72 children, aged 6–18 years, with one of the following diagnosis: a Fontan circulation, BPD, Pompe disease and IBD. Eligible patients will participate in the 12-week tailored exercise intervention and are either randomized to start with a control period or start with the intervention. The tailored 12-week exercise interventions, possibly including a personalized dietary advice and/or psychological counseling, will be designed based on the found limitations for physical activity in each disease group during baseline measurements by the Rotterdam Exercise Team. Effects of the tailored training interventions will be measured on the following endpoints: exercise capacity (measured by cardiopulmonary exercise test), endurance, physical activity levels, muscle strength, quality of life, fatigue, fear for exercise, disease activity, cardiac function (in children with a Fontan circulation), energy balance, and body composition.Ethics and Dissemination: Conducted according to the Declaration of Helsinki and Good Clinical Practice. Medical-ethical approval was obtained.Trial Registration Number: NL8181, https://www.trialregister.nl/trial/8181.

Pain and physical activity levels among Rheumatoid Arthritis patients between the ages of 18 to 50 years in South Africa

Background: Little epidemiological research on rheumatoid arthritis (RA) has been done in Africa, suggesting that it is an uncommon illness. In rural South Africa, RA has an overall prevalence of 0.07% and a prevalence of 2.5% in urban areas; therefore, it is not as uncommon as perceived by the lack of research. Patient-centred programmes to improve physical function have been lacking and, as a result, the prior assumption was that physical activity should be avoided. Objectives: To determine pain and physical activity levels among RA patients between the ages of 18 to 50 years in South Africa. Methods: A combination of two questionnaires were used, namely, the Global Physical Activity Questionnaire (2002) and the Pain Outcomes Questionnaire (2003). The collated questionnaires were distributed by rheumatologists and on social media platforms to RA patients between the ages of 18 to 50 years old living in South Africa. This study had a sample size of 105 participants, with participation occurring through the online Google forms platform. Results: One hundred and five participants with RA were recruited with an average age of 38±9 years. Most of the participants were females (93.3%). Seventy-two percent of the sample was classified as physically active, where work, leisure and travel activities were considered. No significant correlation between pain and physical activity was evident (r=0.10; p=0.311). Results showed significant correlations between pain and personal grooming (r=0.30; p=0.002), pain and ambulation (r=0.60; p=0.000), and pain and stair climbing (r=0.60; p=0.000). Conclusion: Physical activity has proven to have multiple benefits for those suffering with RA. In this South African sample of RA patients, the majority were classified as physically active, and pain did not affect the activity levels of the involved participants. This study opens further research questions regarding RA prevalence in South Africa, and the type and intensity of physical activity that would be beneficial for RA.

Long-term Effect of Regular Physical Activity and Exercise Habits in Patients With Early Parkinson Disease

Objective:Owing to the lack of long-term observations and/or comprehensive adjustment for confounding factors, reliable conclusions regarding long-term effects of exercise and regular physical activity in Parkinson’s disease (PD) have yet to be drawn. Here, using data from the Parkinson’s Progression Markers Initiative study that includes longitudinal and comprehensive evaluations of many clinical parameters, we examined the long-term effects of regular physical activity and exercise habits on the course of PD.Methods:In this observational cohort study, we primarily used the multivariate linear mixed-effects models to analyze the interaction effects of their regular physical activity and moderate-to-vigorous exercise levels, measured through the Physical Activity Scale for the Elderly questionnaire, on the progression of clinical parameters, after adjusting for age, sex, levodopa-equivalent dose, and disease duration. We also calculated bootstrapping 95% confidence intervals (CIs), and conducted sensitivity analyses using the multiple imputation method and subgroup analyses using the propensity score matching to match for all baseline background factors.Results:237 early PD patients [median (interquartile range); age, 63.0 (56.0–70.0) years; Male, 69.2%; follow-up duration, 5.0 (4.0–6.0) years] were included. Regular physical activity and moderate-to-vigorous exercise levels at the baseline did not significantly affect the subsequent clinical progression of PD. However, average regular overall physical activity levels over time were significantly associated with slower deterioration of postural and gait stability [standardized fixed-effects coefficients of the interaction term (βinteraction) = -0.10 (95% CI, -0.14 to -0.06)], activities of daily living [βinteraction = 0.08 (95% CI, 0.04 to 0.12)], and processing speed [βinteraction = 0.05 (95% CI, 0.03 to 0.08)] in PD patients. Moderate-to-vigorous exercise levels were preferentially associated with slower decline of postural and gait stability [βinteraction = -0.09 (95% CI, -0.13 to -0.05)] and work-related activity levels were primarily associated with slower deterioration of processing speed [βinteraction = 0.07 (95% CI, 0.04 to 0.09)]. Multiple imputation and propensity score matching confirmed the robustness of our results.Conclusions:In the long-term, the maintenance of high regular physical activity levels and exercise habits was robustly associated with better clinical course of PD, with each type of physical activity having different effects.Trial Registration Information:Clinicaltrials.gov (NCT01176565). A link to trial registry page is https://clinicaltrials.gov/ct2/show/NCT01141023.Classification of Evidence:This study provides Class II evidence that sustained increase in overall regular physical activity levels in patients with early Parkinson disease was associated with slower decline of several clinical parameters.

Effects of COVID-19 Lockdown on Managing Diabetes Mellitus Among Sudanese Insulin Pump Users, A Cross-Sectional Study

Background COVID-19 lockdown has affected diabetes management among the insulin pump users by changing their life style, affected their mental health, limited diabetes and insulin pump supplies and more difficult communication with the healthcare providers Objectives The aim of this research is to study the effects of COVID-19 lockdown on managing diabetes mellitus among Sudanese insulin pump users, Sudan (March- September 2020). Methodology: This is a descriptive cross-sectional community based study which was done in contact with Shimaa medical CO. LTD. 26 insulin pump users were chosen by total coverage and the data was collected throughout phone call interviews. All statistical analyses were performed using IBM SPSS Statistics software, version 20. Results The mean age of 22 participants was 25.3 ± 17.2 years, and the majorities (63.6%) were females. The average duration of diabetes was 6.9 ± 3.9 years, and the average duration of insulin pump use was 3 ± 1 years. Of the 22 patients (90.9%) used glucometer for monitoring blood sugar. 9 (40.9%) were less subjective to depression, 9 (40.9%) had moderate susceptibility to have depression. 8 patients (36.4%) reported weight gain, 12 patients (54.5%) reported no weight changes, while 2 patients (9.1%) reported weight loss. The level of physical activity decreased in 10 patients (45.5%), and the dietary habits remained unchanged in 50%. Moreover, participants who reported a decrease in physical activity levels were more likely to report weight gain (P = 0.004) compared with those who reported an increase in physical activity levels. Most of the patients have unchanged behaviors regarding experiencing hyper and hypoglycemic symptoms 45.5%, 72.7% respectively. Most of the patients have unchanged adherence to the insulin pump behaviors, carb counting (63.6%), bolus wizard during mealtime (68.2%), and bolus wizard for hyperglycemia correction (68.2%), self-monitoring of blood glucose (40.9%). (40.9%) of the patients had scheduled phone call appointments, 5 patients (22.7%) received virtual education (VE) from the insulin pump technician. 12 patients (54.5%) reported difficulty obtaining at least one type of insulin pump supply. Conclusion COVID-19 lock down has led to the decrease in physical activity with unchanged dietary habits. Getting the insulin pump supplies was difficult for most of the patient’s, and there was shortage and increase prices for diabetes care supplies. Telemedicine should be considered seriously to ease the communication between the patients and the health care providers.

Factors That Shape Women’s Physical Activity: Development of the Reasons to Participate in Physical Activity Scale (RPPAS)

(1) Background: Obesity could deepen women’s susceptibility to COVID-19 infections and deaths. While physical activity has the potential to improve women’s physical and psychological resilience to the pandemic, there is a dearth of research on factors that motivate women’s participation in physical activity. Thus, to bridge the research gap, this study aims to identify factors that motivate women’s participation in physical activity. (2) Methods: An online survey on motivations for physical activity was developed and distributed to the participants. A total of 108 women offered complete answers (N = 108, 18–33 years old, Mage = 20.34 ± 2.42 years). Participants selected factors that promote their physical activity from a list of 34 factors from the Reasons to Participate in Physical Activity Scale (RPPAS) developed in this study. (3) Results: Exploratory factor analysis revealed that factors that motivate women’s participation in physical activity are: enjoyment and gratification, consideration for other activities (i.e., exergaming), health benefits, networking opportunities, and appearance and performance. Multiple linear regression analyses indicate that only consideration for appearance and performance was significantly associated with participants’ physical activity levels after controlling for compounding factors. (4) Conclusions: The findings of this study underscore the importance of appearance and performance in shaping women’s participation in physical activity. Furthermore, the results also emphasize the need for a nuanced understanding of factors that influence women’s physical activity levels. Future research could investigate how to leverage these motivators in tailored health interventions that aim to improve women’s physical activity.

CHoosing Active Role Models to INspire Girls (CHARMING): protocol for a cluster randomised feasibility trial of a school-based, community-linked programme to increase physical activity levels in 9–10-year-old girls

Background In the UK, there is evidence that girls’ physical activity tends to decline to a greater extent than boys as they enter adolescence. ‘Role models’ could play a vital role in inspiring girls to become or remain physically active. The CHARMING Programme is a primary school-based community linked role-model programme, co-developed in 2016, with children, parents, schools and wider stakeholders. It involves different types of physical activity delivered for 1-h each week by a community provider and peer role models (e.g. older girls from secondary schools) joining in with the sessions. The programme ultimately aims to increase and sustain physical activity levels among 9–10-year-old girls. This study aims to assess the feasibility and acceptability of the CHARMING Programme and of evaluating it using a randomised trial. Methods This study is a feasibility cluster randomised controlled trial, with embedded process evaluation and health economic evaluation. Approximately 90 Year 5 (i.e. 9–10-year-old) girls will be recruited across six primary schools in Mid-South Wales. Participating schools will be allocated to the programme: control on a 2:1 basis; four intervention schools will run the CHARMING Programme and two will continue with usual practice. A survey and accelerometer will be administered at baseline and repeated at 12 months. Interviews and focus groups will be conducted post-intervention delivery. The primary aim is to assess feasibility of a future randomised trial via the recruitment of schools, participants and role models; randomisation; retention; reach; data collection completion rates; programme adherence; and programme fidelity, views on intervention acceptability and programme barriers and facilitators. Secondary aims are to evaluate established physical activity outcome measures for children plus additional health economic outcomes for inclusion in a future full-scale trial. Discussion The results of this study will inform decisions on whether and how to proceed to a full-scale evaluation of the effectiveness and cost-effectiveness of the CHARMING Programme to improve or sustain physical activity.
