Bariatric Surgery: An Opportunity to Improve Quality of Life and Healthy Habits.

Bariatric surgery therapy (BST) is an effective treatment for obesity; however, little is known about its impacts on health-related quality of life (HRQoL) and related factors. This study aimed to evaluate changes in HRQoL and its relationship with weight loss, depression status, physical activity (PA), and nutritional habits after BST. Data were obtained before and 18 months postprocedure from 56 obese patients who underwent BST. We administered four questionnaires: Short Form-36 health survey for HRQoL, 14-item MedDiet adherence questionnaire, Rapid Assessment of PA (RAPA) questionnaire, and Beck's Depression Inventory-II. Multivariable linear regression analysis was used to identify factors associated with improvement in HRQoL. After the surgery, MedDiet adherence and HRQoL improved significantly, especially in the physical component. No changes in PA were found. Patients without previous depression have better mental quality of life, and patients who lost more than 25% of %TBWL have better results in physical and mental quality of life. In the multivariable analysis, we found that %TBWL and initial PCS (inversely) were related to the improvement in PCS and initial MCS (inversely) with the MCS change. In conclusion, BST is an effective intervention for obesity, resulting in significant weight loss and improvements in HRQoL and nutritional habits.

Physical Activity Fragmentation and Falls in Older Adults: Findings from the National Health and Aging Trends Study.

Physical activity (PA) may be an important fall prevention strategy. Current PA guidelines emphasize total PA dose, but daily patterning of PA is underappreciated. With aging, PA bouts become less frequent and shorter in duration (i.e.: more fragmented). PA fragmentation may be an indicator of fall risk, but the relationship is not well understood. This study examined daily PA accumulation and patterns with fall risk in older adults. Participants (n=685, 54.3% female, 61.5% aged 70-79 years) from the National Health and Aging Trends Study (NHATS) with wrist-worn accelerometry PA data from Round 11 (baseline) and sample person interviews with fall data from Round 12 (follow-up) were included. PA variables were categorized into tertiles and incident falls were defined as ≥1 self-reported fall in the year following the PA assessment between baseline and follow-up. A modified Poisson approach was used to estimate the relative risk of both PA accumulation and fragmentation with falls. Overall, 40.0% reported an incident fall. After adjustment for sociodemographic and health characteristics, those in the highest tertile of total PA accumulation had lower fall risk (aRR=0.74, 95% CI: 0.57, 0.95) and those in the highest tertile of PA fragmentation had increased fall risk (aRR=1.33, 95% CI: 1.03, 1.73). Models were attenuated after adjustment for physical functioning. PA fragmentation may identify fall risk in older adults. Longitudinal studies are needed to disentangle the temporal sequencing of the complex relationship between PA and physical functioning across the life-course.

Prevalence and associated factors of locomotive syndrome in young Japanese adults: a cross-sectional study

BackgroundThe onset of locomotive syndrome (LS) precedes that of frailty. Therefore, the first step in extending healthy life expectancy is to implement measures against LS in young adults. The aim of this study was to investigate the prevalence of LS and its associated factors in young adults for early detection and prevention of LS.MethodsThe participants of this study comprised 413 university students specializing in health sciences (192 males and 221 females) with an average age of 19.1 ± 1.2 years. All participants voluntarily participated in the study and reported no serious health problems. The presence or absence of LS was evaluated using the stand-up test, two-step test, and the 25-question Geriatric Locomotive Function Scale. Additionally, musculoskeletal assessment (one-leg standing, squatting, shoulder elevation, and standing forward bend), body composition analysis (weight, body mass index, body fat mass, body fat percentage, skeletal muscle mass index (SMI), and phase angle), handgrip strength test, physical activity assessment, and nutritional assessment were conducted. Sex-stratified analyses were performed, comparing groups with and without LS. Factors associated with LS were explored using binomial logistic regression.ResultsOf the 413 young adults studied, 86 individuals (20.8%) were found to have LS. When stratified by sex, LS was observed to have a considerably higher prevalence in females (55, 24.9%) than in males (31, 16.1%). In males, the notable differences between the groups with and without LS were observed in one-leg standing and phase angle, whereas in females, differences were identified in body fat mass, body fat percentage, SMI, musculoskeletal pain, and handgrip strength. Two types of binomial logistic regression analysis revealed that the inability to perform one-leg standing was associated with LS in males, while the presence of musculoskeletal pain and a high body fat percentage were identified as factors associated with LS in females.ConclusionsOne in five young adults were found to have LS in this study, underscoring the necessity for early intervention and LS health education. Furthermore, effective management of musculoskeletal pain is also crucial.

The expected changes with different periods of home-based resistance exercise in patients with chronic kidney disease.

The comprehensive impact of prolonged home-based resistance training on individuals grappling with chronic kidney disease (CKD) have yet to be fully elucidated. This study aimed to explore the outcomes of varying exercise durations on physical performance, nutritional status, and kidney function within this specific population, encompassing patients undergoing dialysis and those affected by severe sarcopenia. This was a 1-year observational double cohort study following a 52-week longitudinal design, we enrolled 101 adult CKD outpatients. These participants were divided into two groups: the continuous group, comprising individuals who consistently exercised for over 6 months, and the interrupted group, which included those who did not sustain regular exercise for the same duration. The exercise regimen involved resistance exercises conducted at least 3 to 5 days per week, involving activities like lifting dumbbells and executing weighted wall squats. Physical activity assessments and biochemical blood tests were conducted at weeks 0, 4, 16, 28, 40, and 52 for all participants. The continuous exercise group exhibited better handgrip strength and sit-to-stand movement compared to the interrupted group. Their estimated glomerular filtration rate stayed steady while the interrupted group was declined. Additionally, those who exercised consistently had better metabolism: higher carbon dioxide levels, increased albumin, better nutritional scores, and lower levels of blood urea nitrogen, creatinine, fasting blood glucose, and body weight. Subsequent adjustments for potential confounding factors continued to show improved physical performance and kidney function over time. Our findings indicate the advantageous impact of extended resistance exercise training on overall health of CKD patients, even those on dialysis or with severe sarcopenia. Dedication to this exercise routine could improve kidney function, metabolism, and physical abilities in these patients.

Hybrid compared to conventional pulmonary rehabilitation: an equivalence analysis.

Pulmonary rehabilitation (PR) is a well-established intervention for patients with COPD, but access, uptake and completion are low. This retrospective propensity-matched study aimed to analyse equivalence from a hybrid PR modality against conventional PR. Between 2013 and 2019, 214 patients with COPD with valid baseline physical activity assessments enrolled in conventional PR for three times per week for 3 months. In 2021-2022, 44 patients with COPD enrolled in 3 months of hybrid PR, introducing two providers: once per week in the outpatient centre and two times per week in a primary care setting near the patient's home. All sessions were supervised. Propensity score matching (1:1) was performed. Equivalence between both programmes was analysed for exercise capacity with the equivalence margins of ±30 m on the 6-min walk distance (6MWD). Clinical outcomes, accessibility and adherence were compared using t-tests. 44 patients (mean±sd age 67±8 years; forced expiratory volume in 1 s (FEV1) 47±15% predicted; 6MWD 355±122 m) in the hybrid PR group were matched to 44 patients (mean±sd age 66±8 years; FEV1 46±17% predicted; 6MWD 354±103 m) in the conventional PR group. Equivalence on the increase in 6MWD could not be confirmed; nevertheless, both groups improved their 6MWD clinically significantly (hybrid PR change 63 m (90% CI 43-83 m); conventional PR change 39 m (90% CI 26-52 m)). Changes in quality of life and symptoms were similar. Dropout in hybrid PR (23%) was comparable to conventional PR (27%) (p=0.24). Adherence in both groups was high and accessibility was better for patients following hybrid PR. Hybrid PR can be offered as an effective alternative to conventional PR, if patients are willing to take up the offer.

DOES MOTOR PROFICIENCY INFLUENCE SLEEP, PHYSICAL ACTIVITY AND MENTAL WELLBEING IN AUSTRALIAN CHILDREN?

INTRODUCTION Motor impairments such as poor timing, balance, sequencing, and dexterity often impact on the child’s quality of life, both physically and emotionally. Sleep and physical activity are modifiable behaviours that have a bi-directional association with mental health outcomes. However, there is very limited research on sleep in children with motor difficulties. The aim of this study is to examine if level of motor proficiency influences physical activity, sleep behaviour, and mental well-being. METHODS Children aged between 6 and 12 years attended one ∼90-minute testing session where they completed the Movement Assessment Battery for Children (MABC; 2nd edition), the Test of Gross Motor Development (TGMD; 3rd edition), and a brief physical activity assessment. Questionnaire were completed by the children and parents (Adolescents Motor Competence Questionnaire (AMCQ), Short Moods and Feelings, Kids Screen, Strength and Difficulties Questionnaire, Children’s Sleep Habits Questionnaire (CSHQ). RESULTS Currently, 15 children (9 males, mean age 9.2 ± 1.97 yrs) have completed the study. Preliminary results show a mean TGMD index of 104.93 ±1.97, suggesting motor skills performed to an average level. The MABC percentile rank was 56.93 ±27.05, one participant below 5th percentile (motor impairment). AMCQ mean 87.00±8.9, however four participants had perceived low motor competence. Interestingly mean sleep score suggests high sleep disturbance among the sample (CSHQ mean 42.33 ± 9.73) with 9 out of 15 participants identifying with a paediatric sleep disorder (three low motor competence and six high motor competence has a paediatric sleep disorder). CONCLUSION Results indicate some interesting findings with both high and low motor competence children demonstrating a sleep disorder. Further analysis looking at actigraph sleep data, sleep diary and physical activity collected over 7 days will be presented during the conference.

Характеристика пацієнтів з ішемічною хворобою серця та стабільною стенокардією в Україні, оцінка підходів до їх лікування за даними багатоцентрового дослідження GO-OD

Treatment of coronary artery disease (CAD) and stable angina, includes lifestyle modification, pharmacological therapy and invasive interventions to achieve stabilization or regression of the disease. Knowledge of the current situation regarding the use of pharmacological therapy and evaluation of its effectiveness is necessary for further management optimization. Trimetazidine (TMZ) has previously been shown to reduce angina symptoms and increase exercise tolerance in patients with CAD and stable angina and may be among an option for optimizing antianginal treatment. However, the effectiveness of long-term treatment depends on patient adherence, so the use of TMZ once daily (OD) at a dose of 80 mg may improve satisfaction and adherence in patients with CAD and stable angina.Methods. The GO-OD study is a 3-month, non-interventional, observational, multicenter prospective study conducted in Ukraine in a real-world outpatient cardiology practice during February – August 2021. Physicians were instructed to continue monitoring and treating patients in accordance with usual practice and international guidelines. No additional diagnostic or monitoring procedures were performed. Clinical, instrumental and laboratory data, frequency of angina attacks, consumption of short-acting nitrates (SAN), adherence to antianginal drugs, as well as the overall efficacy, tolerability of TMZ OD 80 mg in real-world clinical practice were analyzed. The observation includes regular assessment of patients` clinical status, treatment optimization and its effectiveness at follow up visits.Results. The study included 1529 patients (mean age 62.5 years, 56 % men). In the absence of adequate control of risk factors, pharmacological control of symptoms, and limited use of interventional and surgical treatments, the frequency of angina episodes was high, most patients had a pronounced angina functional class according to the Canadian Society of Cardiology classification (10.5 % – CCS I, 60.1 % – CCS II, 29.5 % – CCS III). Thus, the average number of angina attacks per week in CCS I was 3.7, in CCS II – 5.2, and in CCS III – 7, 97 attacks. In addition to the severity of symptoms, the following pattern was observed: the higher the angina class, the more risk factors and comorbidities patients had. After 3 months of follow-up due to optimization of therapy, there was a significant (p<0.001) decrease in the frequency of angina attacks – from (5.8±4.7 to 1.6±2.0)/week, and the use of SAN – from (4.2±4.3 to 0.8±1.6)/week). At the same time, in 3 month the % of patients with CCS II and III significantly decreased, while the % of patients with CCS I increased (48.4 % – CCS I, 45.7 % – CCS II, 6 % – CCS III). Adherence to medication was improved: 49 % of patients reported high adherence (vs. 18 % at baseline) and 12 % – low adherence (vs. 52 % at baseline). After 3 months of follow-up most of doctors rated the overall tolerability and effectiveness of the therapy as «very satisfied». Patients’ satisfaction with TMZ OD 80 mg therapy after 3 months of follow-up was 9.5 points [on a scale of 1 to 10 (very satisfied)]. Patients’ assessment of daily physical activity increased significantly: 2.42 versus 5.89 points at baseline (on a scale of 1 to 10 (severe limitation)).Conclusions. In general, the management of outpatients with CAD and stable angina in the current cardiologists’ practice, which was complicated by the COVID-19 pandemic, was not effective enough, resulting in a high frequency of angina attacks – almost 6 per week, and a significant limitation of daily activity due to angina symptoms.Significant deficiency in the management of studied population was insufficient correction of such important risk factors as hypertension, heart rate, dyslipidemia, and lifestyle-related risk factors (overweight and obesity, low level of physical activity). The baseline therapy of patients in the study was in line with current guidelines, but with an insufficient frequency of statin prescription (78 %) and ACE inhibitors (54.5 %); antianginal treatment with an average of 2 or more antianginal drugs was not optimal for controlling angina symptoms, and the frequency of coronary revascularization procedures was also insufficient, mostly during acute MI (58.0 %).Optimization of drug therapy as the first step in correcting the condition of patients with CAD and stable angina in accordance with all current recommendations with the inclusion of the original trimetazidine OD 80 mg once daily among antianginal drugs, as well as active monitoring of patients for 3 months allowed to reduce the frequency of angina attacks regardless of its initial FC, increase patient adherence to treatment and their functional activity.

Fourteen-year trends in overweight, general obesity, and abdominal obesity in Amazonian indigenous peoples.

Available data show that the epidemiological profile of most indigenous Brazilian populations is characterized by the coexistence of long-standing health problems (high prevalence of infectious and parasitic diseases, malnutrition, and deficiency diseases, such as anemia in children and women of reproductive age), associated with new health problems, especially those related to obesity (hypertension, type 2 diabetes mellitus and dyslipidemia). Based on this scenario, this study analyzed the nutritional profile of the adult population of seven indigenous peoples from the Brazilian Amazon in the years 2007 and 2021. A total of 598 adults individuals were analyzed in 2007 (319 women and 279 men) and 924 in 2021 (483 women and 441 men), from seven indigenous peoples located in the state of Pará, who were assisted during health actions carried out in 2007 and in 2021. Body mass index classification used the World Health Organization criteria for adults: low weight, < 18.5kg/m2; normal weight, ≥ 18.5 and < 25kg/m2); overweight, ≥ 25 and < 30kg/m2, and obesity, ≥ 30kg/m2. A waist circumference (WC) < 90cm in men and < 80cm in women was considered normal. The data revealed heterogeneous anthropometric profiles, with a low prevalence of nutritional changes in the Araweté, Arara and Parakanã peoples, and high proportions of excess weight and abdominal obesity in the Kararaô, Xikrin do Bacajá, Asurini do Xingu and Gavião peoples, similar to or even higher than the national averages. Different stages of nutritional transition were identified in the indigenous peoples analyzed, despite apparently having been subjected to the same environmental pressures that shaped their nutritional profile in recent decades, which may indicate different genetic susceptibilities to nutritional changes. The evidence shown in this study strongly suggests the need to investigate in greater depth the genetic and environmental factors associated with the nutritional profile of Brazilian indigenous peoples, with assessment of diet, physical activity and sociodemographic and socioeconomic variables that enable the development of appropriate prevention and monitoring measures.

Expanding active living after cancer to underserved cancer survivors and their caregivers.

Physical activity improves physical and psychological health in cancer survivors. This study evaluated Active Living After Cancer (ALAC), a community-based program to improve physical activity, physical function, and quality of life (QOL) in minority and medically underserved cancer survivors and their caregivers. Participants completed 12 weekly ALAC sessions and assessments of physical activity, physical functioning, and QOL at baseline and follow-up (week 12). Paired samples t tests were used to assess changes in outcomes over time. A total of 540 cancer survivors (mean age = 61.1 [SD = 11.3] years) and 87 caregivers (mean age = 62.3 [SD = 13.1] years) were enrolled. Most were women (91.4%), Hispanic (61.1%) or non-Hispanic Black (19.3%), and medically underserved (86.4%). The percent of cancer survivors meeting physical activity recommendations increased from 28.9% to 60.2% (d = 0.75), and the number of sit-to-stand repetitions in a 30-second period increased from 12.3 to 14.3 (d = 0.39) from 0-12 weeks. Cancer survivors reported statistically significant improvements in physical (t score Δ = 1.7, d = 0.06) and mental (t score Δ = 2.3, d = 0.31) health-related QOL. Caregivers also improved their physical activity, physical function, and QOL, and there were no statistically significant differences between breast and other cancer survivors and between cancer survivors and caregivers. The ALAC program demonstrated increased physical activity, physical function, and QOL in medically underserved cancer survivors and their caregivers. Furthermore, ALAC was successfully implemented by community partners and serves as a good model for reaching medically underserved cancer survivors and improving survivorship. Additional efforts are warranted to further extend reach, improve cancer survivorship, and reduce cancer health disparities among underserved cancer survivors.

Correlation between Physical Activity Time Reported by the IPAQ and Accelerometer in Syrian Adults

Background: The accelerometer and self-report questionnaires have been recommended as efficient methods to measure physical activity (PA). The aim of this work is to investigate issues associated with PA assessment using the ActiGraph WGT3X-BT (AG) accelerometer and the Syrian version of the International Physical Activity Questionnaire-short form (IPAQ-SF-SY) in adults living in Damascus city.Methods: A sample of 52 (age 18- 60 years) Syrian men (17) and women (35) in a cross-sectional study wore the AG accelerometer for seven days and completed the IPAQ-SF-SY on the seventh day. Total PA, time spends in standing and sitting assessed by IPAQ-SF-SY and AG accelerometer were compared.Results: The IPAQ-SF-SY overestimates PA time among Syrian adults. IPAQ-SF-SY reported more time of total PA [763(660) vs 607(149) min, p=0.003], vigorous PA [29(1) vs 1(0.2) min, p=0.524], moderate PA [94(76) vs 42(22) min, p=0.032], MVPA [122(106) vs 43(22) min, p=0.019], and significantly less sedentary time than AG accelerometer [447(180) vs 643(93) min, p=0.728], mean (SD) respectively. Some differences were noticed in the correlations by gender, age, BMI, education statues, and smoking for PA and sedentary behavior (SB). For all correlations, there were no significant differences between sub groups.Conclusions: Data suggest that it is important to improve the specificity and sensitivity of the IPAQ-SF-SY with Arabic-speaking subjects and further study is needed to approve the utilization of PA self-report in Arabic.

An Assessment of Physical Activity and Risk Factors in People Living with Dementia: Findings from a Cross-Sectional Study in a Long-Term Care Facility in Vietnam.

People living with dementia (PLWD) may experience substantial cognitive decline as the disease progresses, which interferes with their daily activities. This study aimed to assess physical activity (PA) performance and care dependency (CD) and identify factors related to PA among PLWD. We conducted a cross-sectional study in 63 PLWD from National Geriatrics Hospital, Vietnam, from 2021 to 2023. We used the Mini Nutritional Assessment (MNA), International Physical Activity Questionnaire (IPAQ), and Care Dependency Scale (CDS) to assess the nutritional status and the levels of PA and CD, respectively. We used the Mann-Whitney test to compare the differences in the PA types and CD levels between dementia levels and a multivariable logistics regression model to analyze factors related to PA. More than half of the subjects had mild dementia. In total, 35% of the PLWD had a low level of PA, and 46.3% were completely independent of care. The mean score in each CDS aspect of the subjects with moderate/severe dementia was statistically significantly lower than that of those with mild dementia (p ≤ 0.05). Lower dependency (OR = 0.9; 95% CI = 0.88-0.99) and malnutrition (OR = 15.4; 95% CI = 1.18-20.21) were associated with insufficient PA in the PLWD. Formal caregivers and healthcare workers should encourage PLWD to perform physical activities at any level and personalize the development of tailored and nutritional care strategies for each individual.

Objective Assessment of Physical Activity at Home Using a Novel Floor-Vibration Monitoring System: Validation and Comparison With Wearable Activity Trackers and Indirect Calorimetry Measurements.

The self-monitoring of physical activity is an effective strategy for promoting active lifestyles. However, accurately assessing physical activity remains challenging in certain situations. This study evaluates a novel floor-vibration monitoring system to quantify housework-related physical activity. This study aims to assess the validity of step-count and physical behavior intensity predictions of a novel floor-vibration monitoring system in comparison with the actual number of steps and indirect calorimetry measurements. The accuracy of the predictions is also compared with that of research-grade devices (ActiGraph GT9X). The Ocha-House, located in Tokyo, serves as an independent experimental facility equipped with high-sensitivity accelerometers installed on the floor to monitor vibrations. Dedicated data processing software was developed to analyze floor-vibration signals and calculate 3 quantitative indices: floor-vibration quantity, step count, and moving distance. In total, 10 participants performed 4 different housework-related activities, wearing ActiGraph GT9X monitors on both the waist and wrist for 6 minutes each. Concurrently, floor-vibration data were collected, and the energy expenditure was measured using the Douglas bag method to determine the actual intensity of activities. Significant correlations (P<.001) were found between the quantity of floor vibrations, the estimated step count, the estimated moving distance, and the actual activity intensities. The step-count parameter extracted from the floor-vibration signal emerged as the most robust predictor (r2=0.82; P<.001). Multiple regression models incorporating several floor-vibration-extracted parameters showed a strong association with actual activity intensities (r2=0.88; P<.001). Both the step-count and intensity predictions made by the floor-vibration monitoring system exhibited greater accuracy than those of the ActiGraph monitor. Floor-vibration monitoring systems seem able to produce valid quantitative assessments of physical activity for selected housework-related activities. In the future, connected smart home systems that integrate this type of technology could be used to perform continuous and accurate evaluations of physical behaviors throughout the day.

A Randomized Controlled Cluster Trial of an Obesity Prevention Program for Children with Special Health Care Needs: Methods and Implications.

Children with disabilities have higher prevalence estimates of obesity than typically developing children. The Healthy Caregivers-Healthy Children Phase 3 (HC3) project implemented an obesity prevention program adapted for children with special health care needs (CSHCN) that includes dietary intake and physical activity (PA) components. The primary outcome was a change in dietary intake, PA, and the body mass index (BMI) percentile. Ten childcare centers (CCCs) serving low-resource families with ≥30 2- to 5-year-olds attending were randomized to either the intervention (n = 5) or control (n = 5). The HC3 CCCs received (1) snack, beverage, PA, and screen time policies via weekly technical assistance; (2) adapted lesson plans for CSHCN; and (3) parent curricula. The control CCCs received a behavioral health attention curriculum. HC3 was delivered over three school years, with data collected at five different timepoints. It was delivered weekly for six months in year one. To ensure capacity building, the HC3 tasks were scaled back, with quarterly intervention delivery in year 2 and annually in year 3. Adaptations were made to the curriculum to ensure appropriate access for CSHCN. Given that the program was being delivered during the COVID-19 pandemic, special modifications were made to follow CDC safety standards. The primary outcome measures included the Environment and Policy Assessment and Observation (EPAO) tool, standardized dietary intake and PA assessments, and the child BMI percentile. CCCs are an ideal setting for targeting CSHCN for obesity prevention efforts as they provide an opportunity to address modifiable risk factors.

Identifying the most representative actigraphy variables reflecting standardized hand function assessments for remote monitoring in children with unilateral cerebral palsy

BackgroundAccurate assessment of physical activity and motor function in children with cerebral palsy is crucial for determining the effectiveness of interventions. This study aimed to investigate the correlation between real-world activity monitoring outcomes and in-laboratory standardized hand function assessments in children with unilateral cerebral palsy.MethodsActigraphy data were collected over 3 days from children aged 4–12 years with unilateral cerebral palsy before in-laboratory assessments. To tackle the high dimensionality and collinearity of actigraphy variables, we first applied hierarchical clustering using the Pearson correlation coefficient as the distance metric and then performed a principal component analysis (PCA) to reduce the dimensionality of our data.ResultsBoth hierarchical clustering and PCAs revealed a consistent pattern in which magnitude ratio variables (ln[affected side magnitude/less-affected side magnitude]) were more strongly associated with standardized assessments of hand function than with activity time and distance domain variables. Hierarchical clustering analysis identified two distinct clusters of actigraphy variables, with the second cluster primarily consisting of magnitude ratio variables that exhibited the strongest correlation with Melbourne Assessment 2, Pediatric Motor Activity Log, Assisting Hand Assessment, and Manual Ability Classification System level. Principal component 2, primarily representing the magnitude ratio domain, was positively associated with a meaningful portion of subcategories of standardized measures, whereas principal component 1, representing the activity time and distance component, showed limited associations.ConclusionsThe magnitude ratio of actigraphy can provide additional objective information that complements in-laboratory hand function assessment outcomes in future studies of children with unilateral cerebral palsy.Trial registration in ClinicalTrials.govNCT04904796 (registered prospectively; date of registration: 23/05/2021).

Prediction of walking speed one year following hip fracture based on pre-fracture assessments of mobility and physical activity

BackgroundOlder people with hip fracture are often medically frail, and many do not regain their walking ability and level of physical activity. The aim of this study was to examine the relationship between pre-fracture recalled mobility, fear of falling, physical activity, walking habits and walking speed one year after hip fracture.MethodsThe study had a longitudinal design. Measurements were performed 3–5 days postoperatively (baseline) and at one year after the hip fracture. The measurements at baseline were all subjective outcome measures recalled from pre-fracture: The New Mobility Scale (NMS), the ‘Walking Habits’ questionnaire, The University of California, Los Angeles (UCLA) Activity Scale, Fear of Falling International (FES-I) and demographic variables. At one year 4-meter walking speed, which was a part of the Short Physical Performance Battery (SPPB) was assessed.ResultsAt baseline 207 participants were included and 151 were assessed after one year. Their age was mean (SD) 82.7 (8.3) years (range 65–99 years). Those with the fastest walking speed at one year had a pre-fracture habit of regular walks with a duration of ≥ 30 min and/or a frequency of regular walks of 5–7 days a week. Age (p =.020), number of comorbidities (p <.001), recalled NMS (p <.001), and recalled UCLA Activity Scale (p =.007) were identified as predictors of walking speed at one year. The total model explained 54% of the variance in walking speed.ConclusionsDuration and frequency of regular walks before the hip fracture play a role in walking speed recovery one year following the fracture. Subjective outcome measures of mobility and physical activity, recalled from pre-fracture can predict walking speed at one year. They are gentle on the old and medically frail patients in the acute phase after hip fracture, as well as clinically less time consuming.

Physical Activity Levels and Factors Affecting Them in Hospitalized Children With Leukemia

Background Physical activity promotes healthy physical and mental development in children with leukemia. However, the level of physical activity in hospitalized children with leukemia and the factors that influence it are unknown. Objectives The aims of this study were to understand the physical activity level of hospitalized children with leukemia and to explore the factors influencing it to provide a reference for physical activity assessment and intervention in such children. Methods A total of 133 hospitalized children with leukemia completed a general information questionnaire, the Chinese University of Hong Kong Physical Activity Rating for Children and Youth, and the Children’s Social Anxiety Scale. A cross-sectional study was used to explore the effects of different variables on the children’s activity levels. Results Among the study participants, 44.4% had a low-intensity activity level, 35.3% had a moderate-intensity activity level, and 20.3% had a high-intensity activity level, with a total physical activity rating of 3 (1, 6). Chemotherapy phase (P = .007), screen time (P = .001), and social anxiety (P = .012) were identified as influential factors. Conclusions Our results showed that children with hospitalized leukemia had lower-intensity physical activity levels, especially in the chemotherapy phase of induction remission. Furthermore, screen time and social anxiety had negative effects on the children’s activity levels. Implications for Practice According to the physical activity level of the children and the influencing factors, healthcare professionals should gradually improve children’s mobility and promote their physical and mental health development through guidance and encouragement, and the development of personalized activity intervention programs.

Effects of Regular Exercise on the Biochemical, Oxidative, and Inflammatory Profiles and Quality of Life in Older Spaniards with Metabolic Syndrome.

Metabolic syndrome increases the risk of developing diabetes and cardiovascular disease. The regular practice of physical activity is a crucial factor for healthy aging and for controlling and preventing chronic diseases. To assess the effects of regular physical activity on the biochemical and inflammatory profiles, as well as the quality of life of older adults diagnosed with metabolic syndrome. Participants (aged 55-70 years; living in the Balearic Islands, Spain) were divided into two groups (n = 50 each) according to the degree of physical activity measured by metabolic equivalents of task (METs). Anthropometric parameters, blood pressure, biochemical and hematological parameters, and inflammatory biomarkers were measured. Beck Depression Inventory and adherence to the Mediterranean diet questionnaires, as well as the Dietary Inflammatory Index, chair test, health-related quality of life (HRQoL), and Rapid Assessment of Physical Activity, were also determined. The characterization of the patients was similar in both groups, showing a homogeneous sample. The group with the highest METs experienced a decrease in depression and an increase in the intensity of physical activity. Adherence to the Mediterranean diet and HRQoL physical dimensions increased in participants with the highest METs, also showing a decrease in glycemia and glycosylated hemoglobin values. Inflammatory biomarkers, including tumor necrosis factor alpha, interleukin-6, interleukin-1β, and osteoprotegerin, decreased in patients practicing more physical activity. High levels of physical activity are related to a healthier lifestyle, characterized by high adherence to the Mediterranean diet, decreased depressive behavior, oxidative stress, and inflammatory status in older people with metabolic syndrome.

Orthorexia Nervosa and Healthy Orthorexia in a Physically Active North American Population.

The Teruel Orthorexia Scale (TOS) defines two related but distinct constructs: Orthorexia Nervosa (OrNe), a pathological fixation on a healthy diet, and Healthy Orthorexia (HeOr), an interest in a healthy diet independent of psychopathology. Here, we (a) assessed both types of Orthorexia in a large North American sample using the TOS and (b) explored if engaging in regular physical activity was associated with a greater risk of Orthorexia. A cohort of physically active adults (n = 927; 41% men) completed the TOS, as well as the Rapid Assessment of Physical Activity (RAPA), to broadly assess aerobic physical activity level and participation in strength and/or flexibility training. As expected, scores for HeOr and OrNe differed between participants, with lower scores for Orthorexia Nervosa in our physically active non-clinical sample. Higher HeOr scores were associated with lower BMI, and this was true for both men and women. We also found that measures of Orthorexia were associated with self-reported physical activity: active adults reporting more aerobic physical activity had higher HeOr scores, with the most active men having the highest scores. Notably, adults who reported regular strength training had higher scores for both HeOr and OrNe, with men who strength trained showing higher OrNe scores than women. Here, those who participate in regular strength training are more likely to exhibit orthorexic behaviors, and this effect was more pronounced for men than women. Prior work has validated the TOS in young, primarily female samples of non-English speakers outside the United States: present data from an age-diverse, physically active, gender balanced sample support the use of TOS for measurement of Orthorexia Nervosa and Healthy Orthorexia in English speakers and suggest that more work is needed to assess potential gender differences in these constructs.

Multiparametric Aging Study Across Adulthood in the Leg Through Quantitative MR Imaging, 1H Spectroscopy, and 31P Spectroscopy at 3T.

Improved characterization of healthy muscle aging is needed to establish early biomarkers in age-related diseases. To quantify age-related changes on multiple MRI and clinical variables evaluated in the same cohort and identify correlations among them. Prospective. 70 healthy subjects (30 men) from 20 to 81 years old. 3T/water T2 (multiecho SE, multi-TE STEAM), water T1 (GRE MR Fingerprinting), fat-fraction (multiecho GRE, multi-TE STEAM), carnosine (PRESS), multicomponent water T2 (ISIS-CPMG SE train), and 31P pulse-acquire spectroscopy. Age- and sex-related changes on: Imaging: fat-fraction (FFMRI), water T1 (T1-H2O), and T2 (T2-H2O-MRI) and their heterogeneities ΔT1-H2O and ΔT2-H2O-MRI in the posterior compartment (PC) and anterior compartment (AC) of the leg. 1H spectroscopy: Carnosine concentration, pH, water T2 components (T2-H2O-CPMG), fat-fraction (FFMRS), and water T2 (T2-H2O-MRS) in the gastrocnemius medialis. 31P spectroscopy: Phosphodiesters (PDE), phosphomonoesters, inorganic phosphates (Pi), and phosphocreatine (PCr) normalized to adenosine triphosphate (ATP) and pH in the calf. Clinical evaluation: Body-mass index (BMI), gait speed (GS), plantar flexion strength, handgrip strength (HS), HS normalized to wrist circumference (HSnorm), physical activity assessment. Multilinear regressions with sex and age as fixed factors. Spearman correlations calculated between variables. Benjamini-Hochberg procedure for false positives reduction (5% rate). A P < 0.05 significance level was used. Significant age-related increases were found for BMI (ρAge = 0.04), HSnorm (ρAge = -0.01), PDE/ATP (ρAge = 2.8 × 10-3), Pi/ATP (ρAge = 2.0 × 10-3), Pi/PCr (ρAge = 0.3 × 10-3), T2-H2O-MRS (ρAge = 0.051 msec), FFMRS (ρAge = 0.036) the intermediate T2-H2O-CPMG component time (ρAge = 0.112 msec), and fraction (ρAge = -0.3 × 10-3); and in both compartments for FFMRI (ρAge = 0.06, PC; ρAge = 0.06, AC), T2-H2O-MRI (ρAge = 0.05, PC; ρAge = 0.05, AC; msec), ΔT2-H2O-MRI (ρAge = 0.02, PC; ρAge = 0.02, AC; msec), T1-H2O (ρAge = 1.08, PC; ρAge = 1.06, AC; msec), and ΔT1-H2O (ρAge = 0.22, PC; ρAge = 0.37, AC; msec). The best age predictors, accounting for sex-related differences, were HSnorm (R2 = 0.52) and PDE/ATP (R2 = 0.44). In both leg compartments, the imaging measures and HSnorm were intercorrelated. In PC, T2-H2O-MRS and FFMRS also showed numerous correlations to the imaging measures. PDE/ATP correlated to T1-H2O, T2-H2O-MRI, ΔT2-H2O-MRI, FFMRI, FFMRS, the intermediate T2-H2O-CPMG, BMI, Pi/PCr, and HSnorm. Our multiparametric MRI approach provided an integrative view of age-related changes in the leg and revealed multiple correlations between these parameters and the normalized HS. 1 TECHNICAL EFFICACY: Stage 3.
