Introduction: Physical activity is a key component of a healthy lifestyle for youths with visual impairments (i.e., blindness or low vision). This study aims to examine the habitual physical activity and sedentary time of Chinese children and adolescents with visual impairments and to determine whether age, gender, and body composition significantly influence their behavior. Methods: A purposeful sample method was utilized to recruit 137 Chinese youths with visual impairments from a special school for individuals with visual and hearing impairments. A total of 72 students with visual impairments (aged 7–17 years; M age = 13.4) participated in this study. ActiGraph GT3X accelerometers were used to measure the habitual physical activity and sedentary time. Results: Youths with visual impairments in this study spent an average of 287.86 (standard deviation [ SD] = 45.67) minutes of light physical activity, 146.79 ( SD = 56.95) minutes of moderate physical activity, 18.47 ( SD = 15.15) minutes of vigorous physical activity, 165.26 ( SD = 69.83) minutes of moderate-to-vigorous-intensity physical activity, and 979.51 ( SD = 109.10) minutes of sedentary time per day. Children with visual impairments in elementary school engaged in more habitual physical activity and had less sedentary time than did students in middle and high school. Differences in gender and body composition with regard to time spent being active or sedentary were insignificant. Discussion: Findings demonstrated that Chinese youths with visual impairments in this study had sufficient health-enhancing physical activity and were habitually active. Future research is needed to identify the factors that account for the high habitual physical activity levels of Chinese youths with visual impairments. Implications for practitioners: Transition planning for students with visual impairments to facilitate active habitual physical activity participation when children grow up is warranted.

Chinese Children And Adolescents

China is experiencing significant public health challenges related to social and demographic transitions and lifestyle transformations following unprecedented economic reforms four decades ago. Of particular public health concern is the fourfold increase in overweight and obesity rates in the nation’s youth population, coupled with the low prevalence of adolescents meeting recommended levels of physical activity. Improving the overall health of China’s more than 170 million children and adolescents has become a national priority. However, advancing nationwide health initiatives and physical activity promotion in this population has been hampered by the lack of a population-specific and culturally relevant consensus on recommendations for achieving these ends. To address this deficiency and inform policies to achieve Healthy China 2030 goals, a panel of Chinese experts, complemented by international professionals, developed this consensus statement. The consensus was achieved through an iterative process that began with a literature search from electronic databases; in-depth reviews, conducted by a steering committee, of the resulting articles; and panel group evaluations and discussions in the form of email correspondence, conference calls and written communications. Ultimately, the panel agreed on 10 major themes with strong scientific evidence that, in children and adolescents aged 6–17, participating in moderate to vigorous physical activities led to multiple positive health outcomes. Our consensus statement also (1) highlights major challenges in promoting physical activity, (2) identifies future research that addresses current knowledge gaps, and (3) provides recommendations for teachers, education experts, parents and policymakers for promoting physical activity among Chinese school-aged children and adolescents. This consensus statement aligns with international efforts to develop global physical activity guidelines to promote physical activity and health and prevent lifestyle-related diseases in children and adolescents. More importantly, it provides a foundation for developing culturally appropriate and effective physical activity interventions, health promotion strategies and policy initiatives to improve the health of Chinese children and adolescents.

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.

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.

Sufficient physical activity can help promote and maintain health, while its lack can jeopardize it. Since health and physical activity lay their foundation for later life in childhood and adolescence, it is important to examine this relationship from the beginning. Therefore, this scoping review aims to provide an overview of physical health indicators in children and adolescents in research on the effects of physical activity and sedentary behavior. We identified the indicators used to quantify or assess physical health and summarized the methods used to measure these indicators. We systematically searched Scopus, Pubmed, and Web of Science databases for systematic reviews. The search yielded 4595 records from which 32 records were included in the review. The measurements for physical health reported in the reviews contained measures of body composition, cardiometabolic biomarkers, physical fitness, harm/injury, or bone health. Body composition was the most used indicator to assess and evaluate physical health in children, whereas information on harm and injury was barely available. In future research longitudinal studies are mandatory to focus on the prospective relationships between physical activity or sedentary behavior, and physical health.

Abstract BackgroundThe children’s lipid accumulation product (CLAP) was associated with MS in Chinese children and adolescents. The study was to develop a more effective indicator, relative children’s lipid accumulation product （RCLAP）associated with MS reflect the density of lipid accumulation among Chinese children and adolescents. MethodsA stratified cluster sampling method was used to recruit 683 students aged 8-15 years in this study. The presence of MS was defined according to the NCEP-ATP III criteria. The t-test, chi-square test, logistic regression models were used to analyze the associations of SBMI, SWHtR, SlnCLAP, SRCLAP-H, SRCLAP-SH, RCLAP-W with MS. Receiver Operating Characteristic (ROC) curves was used to evaluate the predictive efficiency of above indexes for predicting MS. ResultsThe overall prevalence of MS was 4.8% (boys 6.6%, girls 2.8%). In girls, after adjusting for sedentary activity time, WHtR, BMI, CLAP, RCLAP-H, RCLAP-SH and RCLAP-W significantly increased risk of MS (OR(95%CI):15.79 (3.15-79.21), 3.73 (0.87-15.95), Null, 96.13 (11.11-831.97), 96.13 (11.11-831.97), 18.28 (4.24-78.87), respectively). In boys, after adjusting for ages and moderate-to-vigorous physical activity time, WHtR, BMI, CLAP, RCLAP-H, RCLAP-SH and SRCLAP-W significantly increased risk of MS (OR(95%CI): 37.43(11.67-120.10), 68.33(18.51-252.20), 105.86(21.99-509.68), 171.75(33.60-878.00), 133.18(27.65-641.39), 50.13(15.48-162.37, respectively). The AUCs of RCLAP-H and RCLAP-SH for predicting MS were 0.950, 0.948 in girls, and 0.952, 0.952 in boys, which were higher than these of BMI, WHtR, CLAP and RCLAP-W.ConclusionThe relative children，s lipid accumulation products（RCLAP-H and RCLAP-SH ) were more effective indicators for predicting MS than BMI, WHtR and CLAP in Chinese children and adolescents.
