Valvular Aortic Stenosis

AbstractPrevious research in children and adolescents with congenital heart defects presents contradictory findings concerning their physical activity (PA) level, due to methodological limitations in the PA assessment. The aim of the present cross-sectional study was to compare PA in children and adolescents treated for valvular aortic stenosis with healthy controls using an improved accelerometer method. Seven-day accelerometer data were collected from the hip in a national Swedish sample of 46 patients 6–18 years old treated for valvular aortic stenosis and 44 healthy controls matched for age, gender, geography, and measurement period. Sports participation was self-reported. Accelerometer data were processed with the new improved Frequency Extended Method and with the traditional ActiGraph method for comparison. A high-resolution PA intensity spectrum was investigated as well as traditional crude PA intensity categories. Children treated for aortic stenosis had a pattern of less PA in the highest intensity spectra and had more sedentary time, while the adolescent patients tended to be less physically active in higher intensities overall and with less sedentary time, compared to the controls. These patterns were evident using the Frequency Extended Method with the detailed PA intensity spectrum, but not to the same degree using the ActiGraph method and traditional crude PA intensity categories. Patients reported less sports participation than their controls in both age-groups. Specific differences in PA patterns were revealed using the Frequency Extended Method with the high-resolution PA intensity spectrum in Swedish children and adolescents treated for valvular aortic stenosis.

Pediatric Concussion

Objectives: To characterize and quantify differences in accelerometer-measured physical activity and sedentary time between children with concussion (within the first month of injury) and 1:1 matched healthy controls. Methods: Secondary analysis of accelerometer data collected on 60 children with concussion and 60 healthy controls matched for age, sex, and season of accelerometer wear. Daily and hourly sedentary time, light physical activity (LPA), moderate physical activity (MPA), and vigorous physical activity (VPA) were compared between groups per independent samples t-tests. Results: Children with concussion (12.74 ± 2.85 years, 31 females) were significantly more sedentary than controls (12.43 ± 2.71 years, 31 females; mean difference [MD], 38.3 minutes/day, p=0.006), and spent less time performing LPA (MD, -19.5 minutes/day, p=0.008), MPA (MD, -9.8 minutes/day, p<0.001), and VPA(MD, -12.0 minutes/day, p<0.001); hour-by-hour analyses showed that these differences were observed from 8:00AM to 9:00PM. Sex-specific analyses identified that girls with concussion were less active and more sedentary than both boys with concussion (MD, 50.8 minutes/day; p=0.010) and healthy girls (MD, 51.1 minutes/day; p<0.010). Days post-injury significantly predicted MPA (β=0.071, p=0.032) and VPA (β=0.095, p=0.004), but not LPA or sedentariness in children with concussion. Conclusion: Clinical management should continue to advise against prolonged rest following pediatric concussion, given the activity debt observed within the first-month of injury. Currently, clinical management of concussion is shifting towards prescribing a single bout of daily sub-maximal aerobic exercise. Interventions aimed at reducing overall sedentary time and increasing habitual physical activity in pediatric concussion also warrant study.

AbstractObjectiveThe aim of the present study was to investigate if context-specific measures of parental-reported physical activity and sedentary behaviour are associated with objectively measured physical activity and sedentary time in children.DesignCross-sectional study.SettingSeven European countries taking part in the IDEFICS (Identification and Prevention of Dietary- and Lifestyle-induced Health Effects in Children and Infants) study.SubjectsData were analysed from 2–9-year-old children (n 5982) who provided both parental-reported and accelerometer-derived physical activity/sedentary behaviour measures. Parents reported their children’s daily screen-time, weekly sports participation and daily outdoor playtime by means of the Outdoor Playtime Checklist (OPC) and Outdoor Playtime Recall Questions (OPRQ).ResultsSports participation, OPC- and OPRQ-derived outdoor play were positively associated with accelerometer-derived physical activity. Television viewing and computer use were positively associated with accelerometer-derived sedentary time. All parental-reported measures that were significantly associated with accelerometer outcomes explained only a minor part of the variance in accelerometer-derived physical activity or sedentary time.ConclusionsParental-reported measures of physical activity and sedentary behaviour are not useful as a proxy for 2–9-year-old children’s physical activity and sedentary time. Findings do not preclude the use of context-specific measures but imply that conclusions should be limited to the context-specific behaviours that are actually measured. Depending on the aim of the study, future research should carefully consider the choice of measurements, including the use of subjective or objective measures of the behaviour of interest or a combination of both.

Relationship Of

The purpose of this study was to summarize the associations of physical activity (PA) and sedentary time (SED) with metabolic health and examine the effects of time reallocation on metabolic health in adolescents using accelerometer data. A literature search was conducted using PubMed, ScienceDirect, Web of Science, Cochran Library, and Google Scholar, and 27 articles were reviewed. Recent research generally confirms the associations of PA and SED with metabolic health. High PA levels and low SED levels had a positive relationship with metabolic health. Moreover, reallocating 10 min of daily SED to PA was associated with better metabolic health indicators. These results were stronger for moderate-to-vigorous physical activity than for light intensity PA. Thus, efforts to convert SED into PA of at least moderate intensity appear to be an effective strategy to prevent metabolic disease development in children and adolescents. However, some of the associations between PA and metabolic health indicators were inconsistent, depending on age, obesity degree, and PA intensity. Additionally, various accelerometer data collection and processing criteria impact the interpretation of the results. Therefore, consistent accelerometer data collection and analysis methods are needed in future studies. Further, intervention studies are required to verify the causality and effectiveness of the isotemporal substitution model.

Background: The literature is unclear as to whether children and adolescents with chronic respiratory diseases (CRDs) differ from their healthy peers in physical activity (PA). Objective: To determine the PA levels measured through accelerometers in children and adolescents with CRDs. Methods: The authors conducted a systematic review using five databases. The authors included studies that assessed the PA measured by accelerometers in children and adolescents with CRDs. Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of evidence. Results: From 11,497 reports returned by the initial search, 29 articles reporting on 4381 patients were included. In the sensitivity analysis, the authors found that children and adolescents with CRDs had a moderate-to-vigorous PA (MVPA) of −0.08 hours per day (95% confidence interval [CI], −0.12 to −0.03 h/d; P = .001), which was lower than the healthy controls; the values for sedentary time (mean difference −0.47 h/d; 95% CI, −1.29 to 0.36 h/d; P = .27) and steps/d (mean difference 361 steps/d; 95% CI −385 to 1707 steps/d; P = .45) were similar for both. Conclusion: Children and adolescents with CRDs have a slight reduction in MVPA in comparison with healthy controls, but sedentary time and steps/d were similar for both.

Background. Regular physical activity in childhood and adolescent plays an important role in reducing the risk of cardiovascular health diseases, diabetes, and obesity in adulthood. However, little is known about physical activity levels (PA) and sedentary time among children and adolescents in Morocco. Objective. To examine gender, type of day, and age grade differences in objectively measured sedentary time, physical activity levels, and physical activity guideline attainment among children and adolescents in Morocco. Method. 172 children/adolescents (mean age = 10.92 ± 1.55 years, 49.4% are boys) were recruited for this study and wore a tri-axial accelerometer (GT3X+) for 7 consecutive days. Time spent in sedentary, PA levels, and daily steps were measured and compared according to gender, age grade, and the type of day (weekdays/weekends). Results. In weekdays children/adolescents spent more time in sedentary than weekends (p < 0.001). Boys were eight times more likely to meet the recommendation for at least 60 min of moderate to vigorous physical activity per day than girls (OR: 8.569; 95% [CI]: 4.23–17.32), p < 0.001. Conclusion. These findings highlight the need for effective and sustainable strategies and programs aiming to promote physical activity and to reduce sedentary behavior among children and adolescents in Morocco.

Background: An important step in accelerometer data analysis is the classification of continuous, 24-hour data into sleep, wake, and non-wear time. We compared classification times and physical activity metrics across different data processing and classification methods.Methods: Participants (n = 576) from the Finnish Retirement and Aging Study (FIREA) wore an accelerometer on their non-dominant wrist for seven days and nights and filled in daily logs with sleep and waking times. Accelerometer data were first classified as sleep or wake time by log, and Tudor-Locke, Tracy, and ActiGraph algorithms. Then, wake periods were classified as wear or non-wear by log, Choi algorithm, and wear sensor. We compared time classification (sleep, wake, and wake wear time) as well as physical activity measures (total activity volume and sedentary time) across these classification methods.Results:M(SD) nightly sleep time was 467 (49) minutes by log and 419 (88), 522 (86), and 453 (74) minutes by Tudor-Locke, Tracy, and ActiGraph algorithms, respectively. Wake wear time did not differ substantially when comparing Choi algorithm and the log. The wear sensor did not work properly in about 29% of the participants. Daily sedentary time varied by 8–81 minutes after excluding sleep by different methods and by 1–18 minutes after excluding non-wear time by different methods. Total activity volume did not substantially differ across the methods.Conclusion: The differences in wear and sedentary time were larger than differences in total activity volume. Methods for defining sleep periods had larger impact on outcomes than methods for defining wear time.

Background: Children and adolescents with disabilities often report low levels of physical activity (PA). Estimating the magnitude of PA disparities has been previously challenged by underreporting and variability in subsampling of disability. Using the National Survey of Children’s Health, this study estimated the population-level PA disparities experienced and the association between disability status and PA engagement. Methods: Weighted prevalence of PA engagement (National Physical Activity Guidelines for Americans (2nd edition) and sports participation) was compared across disability groups for children (n = 20,867, 6–11 y) and adolescents (n = 28,651, 12–17 y) and found to be 12%. Age-stratified multivariable logistic regressions estimated the likelihood of PA engagement as a function of disability status and type, after adjusting for child and household factors. Results: Children, but not adolescents, with disabilities had significantly lower odds of being sufficiently active compared with peers without disabilities (adjusted odds ratio = 0.75; 95% confidence interval, 0.60–0.94). Across age groups, the lowest prevalence rates were observed among those experiencing function and mobility disabilities. Children and adolescents were significantly less likely to participate in sports compared with peers. Conclusion: Children with function and mobility disabilities were identified as priority subpopulations least likely to be sufficiently active. The disparity in sports participation highlights a critical intervention point for increasing PA among children with disabilities.

Background:The first Active Healthy Kids Spanish Report Card aims to gather the most robust information about physical activity (PA) and sedentary behavior of children and adolescents.Methods:A Research Working Group of experts on PA and sport sciences was convened. A comprehensive data search, based on a review of the literature, dissertations, gray literature, and experts’ nonpublished data, was conducted to identify the best sources to grade each indicator following the procedures and methodology outlined by the Active Healthy Kids Canada Report Card model.Results:Overall PA (based on objective and self-reported methods) was graded as D-, Organized Sports Participation as B, Active Play as C+, Active Transportation as C, Sedentary Behavior as D, School as C, and Family and Peers as Incomplete, Community and the Built Environment as Incomplete, and Government as Incomplete.Conclusions:Spanish children and adolescents showed low levels of adherence to PA and sedentary behavior guidelines, especially females and adolescents. There is a need to achieve consensus and harmonize methods to evaluate PA and sedentary behavior to monitor changes over time and to evaluate the effectiveness of policies to promote PA.
