Associations between adherence to 24-Hour Movement Guidelines with continuous metabolic syndrome score among Chinese children and adolescents.

OBJECTIVES: The objective of this study was to evaluate the associations between adherence to 24-Hour Movement Guidelines (24-HMG) with continuous metabolic syndrome score (cMetS) among Chinese children. STUDY DESIGN: Cross-sectional study. METHODS: We conducted a cross-sectional study among 4604 children aged 6-17 years from Shenzhen, China. The 24-HMG was constructed using the self-report information on moderate-to-vigorous physical activity (MVPA), screen time (ST), and sleep duration. The cMetS was calculated based on waist circumference, homoeostatic model assessment for insulin resistance, mean arterial blood pressure, high-density lipoprotein cholesterol, and triglyceride. Multivariate linear regression models were used to assess the associations between adherence to recommendations of 24-HMG and cMetS. RESULTS: Among the participants, 563 (12.23%) students adhered to 3 recommendations of the 24-HMG. We found that adhering to more recommendations was negatively associated with cMetS (P for trend: <0.001). For specific combinations, meeting the ST + MVPA recommendations was negatively associated with cMetS (coefficients [ß]: -0.686; 95% confidence interval [CI]: -1.148, -0.223). Individuals who adhered to all recommendations had a lower cMetS (ß: -0.693; 95% CI: -1.147, -0.238) than those who met none of the recommendations. CONCLUSIONS: Our study showed that adherence to more recommendations of the 24-HMG was associated with lower levels of cMetS in Chinese children and adolescents.

Lifestyle behavior of physiotherapy students from Ecuador upon admission to higher education: a cross-sectional study.

Introduction: Admission to university has been identified as a period involving the adoption of unhealthy lifestyle behaviors. However, few studies have addressed the extent of this experience among Latin American university students. The aim of this study was twofold: first, to describe anthropometric variables, body composition, physical activity, sedentary behavior, sleep duration and quality, diet, and alcohol consumption in first-year students entering physiotherapy school at the Universidad de las Americas in Quito, Ecuador; second, to test differences in these variables between sexes. Methods: A total of 116 students were recruited. Sociodemographic variables, anthropometric indices, body composition, physical activity, sedentary behavior, sleep quality and duration, adherence to 24-hour movement guidelines, physical fitness (i.e., handgrip strength), diet, alcohol consumption, and smoking habits were evaluated. Results: A total of 50 male (43.1%) and 66 female (56.9%) students were assessed. Overall, the adherence to the 24-hour movement guidelines of the students upon admission to university was 8.6%. Conversely, 86 students (74.1%) did not meet any of the recommendations. Upon admission to university, only 8.6% of the students (female 2.6%; male 6%) met the overall 24-hour movement guidelines. Additionally, 82 students (70.7%) needed changes in diet quality, 81 students (69.8%) had significant sleep disturbances, and 22 students (18.9%) had harmful alcohol consumption. A greater proportion of males met all three 24-h movement recommendations (p = 0.025) than females did. In addition, females reported a greater percentage of occasional smokers (p = 0.025) and a greater prevalence of obesity (p < 0.001), a lower level of physical activity (p < 0.001), and a greater percentage of sleep disturbance (p < 0.001). Conversely, males reported greater waist circumference (p = 0.005), weight (p < 0.001), handgrip strength (p < 0.001), and a greater percentage of harmful alcohol consumption (p < 0.001). Discussion: Our study showed that upon admission to university, overall adherence to the 24-hour movement guidelines is low among university students. Additionally, a high percentage of students reported unhealthy lifestyle behaviors, with differences according to sex. Our findings could lead to the use of specific sex-specific strategies for the prevention and promotion of movement and lifestyle behaviors during this critical period.

Association Between Adherence to 24-Hour Movement Guidelines and Noncommunicable Disease Risk in Chinese Adults: Prospective Cohort Study.

BACKGROUND: The increasing annual global deaths are attributable to noncommunicable chronic diseases (NCDs). Adhering to healthy lifestyle behaviors is associated with lower NCD risk, particularly among individuals with ample movement, enough sleep, and reduced sedentariness. Nevertheless, there are only few prospective assessments on the association of interactions between daily activities with NCD prevention, while the associations between adhering to Canadian 24-Hour Movement Guidelines (24HGs) for adults and NCD risks are still unknown. Compared to the general population, obese and overweight populations are at a higher risk of developing NCDs. Currently, it is unclear whether the health benefits of adhering to 24HGs differ between the general population and the obese population. OBJECTIVE: This study explores prospective associations between adherence to 24HGs and NCD risks by weight status among overweight and obese adults in China. METHODS: This decadal study consists of 9227 adults aged 35 years and older without any major NCDs at enrolment in the China Health and Nutrition Survey (2004-2011) and followed up until 2015. The exposure of interest was the overall score of compliance with 24HGs measured by participants' self-report, wherein 1 point was assigned for compliance to each component, resulting in an aggregated score ranging from 0 to 3. The primary outcome was the first occurrence of major NCDs (high blood pressure, stroke, diabetes, cancer, and acute myocardial infarction). Log-binomial regression models were used to evaluate the associations. RESULTS: : Overall, 4315 males and 4912 females, with 25,175 person-years of follow-up, were included in our analyses. The average baseline age was 50.21 (SD 11.04) years. Among the overweight and obese groups, those adhering to 1 (risk ratio [RR] 0.37, 95% CI 0.19-0.74; P=.004), 2 (RR 0.37, 95% CI 0.19-0.72; P=.003), and 3 (RR 0.32, 95% CI 0.14-0.73; P=.006) recommendations of 24HGs had a significantly lower NCD risk than those not adhering to any of the activity guidelines. Among the normal or underweight groups, those adhering to 1 (RR 0.49, 95% CI 0.27-0.96; P=.03) and 3 (RR 0.40, 95% CI 0.17-0.94; P=.03) components had a significantly lower NCD risk than those not adhering to any of the activity guidelines. CONCLUSIONS: In this prospective study, we found that active adherence to recommendations of 24HGs was associated with lower risks of NCDs, especially among overweight and obese participants. Additionally, overweight and obese individuals who met at least 1 component of 24HGs were at a significantly lower risk for NCDs, but this protective effect was not found among individuals in the normal and underweight groups. Individuals with excess body weight who tend to be more susceptible to health risks may gain greater health benefits than the general population by adhering to the recommendations of 24HGs.

Association between meeting the 24-h movement guidelines and psychosocial health in children: A cross-sectional study.

OBJECTIVE: Emerging evidence suggests that meeting the 24-h movement guidelines is associated with optimal mental health. However, there remains some uncertainty regarding this association in children. Therefore, this study aimed to examine the association between meeting the 24-h movement guidelines and psychosocial health in children. METHODS: A cross-sectional study design was employed to investigate 2005 children aged 9-12 years from four districts of Shanghai, China. The 24-h movement behaviours were assessed using selected items from the Health Behaviour in School-aged Children (HBSC) survey questionnaire. Children's self-rated psychosocial health was evaluated using the Strengths or Difficulties Questionnaire (SDQ). Generalised Linear Models with the ordinal logistic module were employed to analyse the association between meeting the 24-h movement guidelines and psychosocial health. RESULTS: The overall prevalence of meeting all three 24-h movement recommendations was 10.2%. Among children, 7.9% of them exhibited abnormal total difficulties, with a notable difference between sex (boys: 11.2%, girls: 7.0%, p = 0.001). Meeting all three 24-h movement behaviour recommendations was associated with reduced total difficulties, emotional symptoms, conduct problems, hyperactivity and peer problems. Furthermore, a dose-response association was observed, indicating that meeting a greater number of 24-h movement behaviour recommendations was associated with enhanced psychosocial health, particularly in boys. CONCLUSION: The findings of this study highlight the positive association between meeting the 24-h movement guidelines and psychosocial health in children. Notably, meeting more of these recommendations was associated with a lower likelihood of experiencing psychosocial problems, with greater benefits observed in boys compared with girls.

24-Hour movement behaviours research during the COVID-19 pandemic: a systematic scoping review.

OBJECTIVES: Many studies examining 24-hour movement behaviours based on the 24-Hour Movement Guidelines (24HMG) have been published during the COVID-19 pandemic. However, no comprehensive reviews summarized and synthesized the evidence concerning studies using 24HMG. The aim of this scoping review was to synthesize the evidence from the 24HMG studies published during the pandemic. METHODS: Three electronic databases (Web of Science, PubMed, EBSCO) were utilized to conduct a literature search. The search procedure adhered to the guidelines set by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Initially, a total of 1339 research articles published in peer-reviewed journals were screened. After eliminating 461 duplicates, 878 articles remained. The titles and/or abstracts of these articles were then cross-checked, and 25 articles were included. Subsequently, two authors independently assessed full-text of articles based on the pre-defined inclusion and exclusion criteria, resulting in the final selection of 16 articles that met the inclusion criteria. Study characteristics (e.g., study population, study design, measurement) were extracted and then summarized. According to the Viable Integrative Research in Time-use Research (VIRTUE) epidemiology, the included studies were further classified into different but interrelated study domains (e.g., composition, determinants, health outcomes). RESULTS: The majority of included articles focused on children and adolescents as study population. This study primarily demonstrated that a low prevalence of meeting the 24HMG among children and adolescents during the COVID-19 pandemic. There has been a decline in the percentage of individuals meeting the 24HMG compared to the pre-COVID-19 period. The majority of included studies focused on sociodemographic factors when examining the correlates of meeting the 24HMG, while a few studies assessed factors of other domains, such as social, cultural, and environmental aspects. CONCLUSION: The COVID-19 pandemic had an impact on healthy 24-hour movement behaviours in children and adolescents. In conjunction with the studies conducted during the COVID-19 pandemic, more studies were encouraged to explore the correlates of meeting the 24HMG and the associated health benefits in wider ranges of populations.

Tools to guide clinical discussions on physical activity, sedentary behaviour, and/or sleep for health promotion between primary care providers and adults accessing care: a scoping review.

BACKGROUND: Health care providers have reported low knowledge, skill, and confidence for discussing movement behaviours (i.e., physical activity, sedentary behaviour, and sleep), which may be improved with the use of tools to guide movement behaviour discussions in their practice. Past reviews have examined the psychometric properties, scoring, and behavioural outcomes of physical activity discussion tools. However, the features, perceptions, and effectiveness of discussion tools for physical activity, sedentary behaviour, and/or sleep have not yet been synthesized. The aim of this review was to report and appraise tools for movement behaviour discussions between health care providers and adults 18 + years in a primary care context within Canada or analogous countries. METHODS: An integrated knowledge translation approach guided this review, whereby a working group of experts in medicine, knowledge translation, communications, kinesiology, and health promotion was engaged from research question formation to interpretation of findings. Three search approaches were used (i.e., peer-reviewed, grey literature, and forward searches) to identify studies reporting on perceptions and/or effectiveness of tools for physical activity, sedentary behaviour, and/or sleep. The quality of included studies was assessed using the Mixed Methods Appraisal Tool. RESULTS: In total, 135 studies reporting on 61 tools (i.e., 51 on physical activity, one on sleep, and nine combining two movement behaviours) met inclusion criteria. Included tools served the purposes of assessment (n = 57), counselling (n = 50), prescription (n = 18), and/or referral (n = 12) of one or more movement behaviour. Most tools were used or intended for use by physicians, followed by nurses/nurse practitioners (n = 11), and adults accessing care (n = 10). Most tools were also used or intended to be used with adults without chronic conditions aged 18-64 years (n = 34), followed by adults with chronic conditions (n = 18). The quality of the 116 studies that evaluated tool effectiveness varied. CONCLUSIONS: Many tools were positively perceived and were deemed effective at enhancing knowledge of, confidence for, ability in, and frequency of movement behaviour discussions. Future tools should guide discussions of all movement behaviours in an integrated manner in line with the 24-Hour Movement Guidelines. Practically, this review offers seven evidence-based recommendations that may guide future tool development and implementation.

How do People Spend their Day? Sociodemographic Disparities in 24-hour Movement Guideline Adherence among US Adults Using 2017-2020 NHANES Data.

INTRODUCTION: The 24-hour movement guidelines recommend that adults be physically active every day, get good sleep quality, and limit sedentary behavior to lower disease risk and improve quality of life. Adherence to these guidelines have not been evaluated among racially and ethnically diverse adults in the United States. The objectives were to: 1) estimate and compare the prevalence of guideline adherence among all adults and separated by age recommendations (ages 18-64; 65 + years); and 2) determine whether the odds of movement adherence differ by sociodemographics. METHODS: Self-reported data from 2017-2020 National Health and Nutrition Examination Survey (NHANES) were analyzed (n = 9,627) using multivariate logistic regression for all adults and age stratified. Sedentary behavior was measured by minutes of sedentary activity per day (< 480 minutes adherent). Sleep was measured by hours per night (7-9 hours adherent ages 18-64; 7-8 hours adherent ages > = 65). Physical activity was measured by minutes of recreational activity per week (150 + minutes adherent). RESULTS: Guideline adherence among all adults was 23.7% (ages 18-64 = 26%: ages 65 + = 14.7%). Guideline adherence was highest among non-Hispanic Asians (28.1%) and lowest among non-Hispanic Blacks (19.2%) (p = .0070). Males (25.8%) were more likely to meet movement guidelines than females (21.8%; p = .0009). In adjusted models, the odds of meeting movement guidelines were lower among non-Hispanic Blacks (OR = 0.81; 95%CI = 0.66-0.98) compared to Whites, females (OR = 0.84; 95%CI = 0.72-0.97) compared to males, and lower education (OR = 0.22; 95%CI = 0.14- 0.35) compared to adults with a college degree or higher. RECOMMENDATION: Future interventions should be developed to improve guideline adherence tailored to particular at-risk groups.

Determinants of recreational screen time behavior following the COVID-19 pandemic among Canadian adults.

The objectives of our study were to examine recreational screen time behavior before and 2 years following the COVID-19 pandemic lockdown, and explore whether components of the capability-opportunity-motivation-behavior (COM-B) model would predict changes in this recreational screen time behavior profile over the 2-year period. This cross-sectional, retrospective study was conducted in March 2022. Canadian adults (n = 977) completed an online survey that collected demographic information, current screen time behavior, screen time behavior prior to the pandemic, and beliefs about capability, opportunities, and motivation for limiting screen time based on the COM-B model. We found that post-pandemic recreational screen time (3.91 ± 2.85 h/day) was significantly higher than pre-pandemic levels (3.47 ± 2.50 h/day, p < 0.01). Three recreational screen time behavior profiles were identified based on the Canadian 24-Hour Movement Guidelines: (1) always met screen time guidelines (≤3 h/day) (47.8%; n = 454); (2) increased screen time (10.1%; n = 96); and (3) never met screen time guidelines (42%; n = 399). The overall discriminant function was found to be significant among the groups (Wilks' λ = 0.90; canonical r = 0.31, χ2 = (14) = 95.81, p < 0.001). The group that always met screen time guidelines had the highest levels of automatic motivation, reflective motivation, social opportunity, and psychological capabilities to limit screen time compared to other screen time profile groups. In conclusion, recreational screen time remains elevated post-pandemic. Addressing motivation (automatic and reflective), psychological capabilities, and social opportunities may be critical for future interventions aiming to limit recreational screen time.

Developing and testing the usability, acceptability, and future implementation of the Whole Day Matters Tool and User Guide for primary care providers using think-aloud, near-live, and interview procedures.

BACKGROUND: Canada's 24-Hour Movement Guidelines for Adults have shifted the focus from considering movement behaviours (i.e., physical activity, sedentary behaviour, and sleep) separately to a 24-h paradigm, which considers how they are integrated. Accordingly, primary care providers (PCPs) have the opportunity to improve their practice to promote all movement behaviours cohesively. However, PCPs have faced barriers to discussing physical activity alone (e.g., time, competing priorities, inadequate training), leading to low frequency of physical activity discussions. Consequently, discussing three movement behaviours may seem challenging. Tools to facilitate primary care discussions about physical activity have been developed and used; however, few have undergone usability testing and none have integrated all movement behaviours. Following a synthesis of physical activity, sedentary behaviour, and sleep tools for PCPs, we developed the Whole Day Matters Tool and User Guide that incorporate all movement behaviours. The present study aimed to explore PCPs' perceptions on the usability, acceptability, and future implementation of the Whole Day Matters Tool and User Guide to improve their relevancy among PCPs. METHODS: Twenty-six PCPs were observed and audio-video recorded while using the Tool and User Guide in a think-aloud procedure, then in a near-live encounter with a mock service-user. A debriefing interview using a guide informed by Normalization Process Theory followed. Recordings were transcribed verbatim and analysed using content analysis and a critical friend to enhance rigour. RESULTS: PCPs valued aspects of the Tool and User Guide including their structure, user-friendliness, visual appeal, and multi-behaviour focus and suggested modifications to improve usability and acceptability. Findings are further discussed in the context of Normalization Process Theory and previous literature. CONCLUSIONS: The Tool and User Guide were revised, including adding plain language, reordering and renaming sections, reducing text, and clarifying instructions. Results also informed the addition of a Preamble and a Handout for adults accessing care (i.e., patients/clients/service-users) to explain the evidence underpinning the 24-Hour Movement Guidelines for Adults and support a person-centered approach. These four resources (i.e., Tool, User Guide, Preamble, Handout) have since undergone a consensus building process to arrive at their final versions before being disseminated into primary care practice.

Development of a ParticipACTION App-Based Intervention for Improving Postsecondary Students' 24-Hour Movement Guideline Behaviors: Protocol for the Application of Intervention Mapping.

BACKGROUND: The Canadian 24-Hour Movement Guidelines for adults provide specific recommendations for levels of physical activity, sedentary behavior, and sleep (ie, the movement behaviors) required for optimal health. Performance of the movement behaviors is associated with improved mental well-being. However, most postsecondary students do not meet the movement behavior recommendations within the Canadian 24-Hour Movement Guidelines and experience increased stress and declining well-being, suggesting the need for an intervention targeting students' movement behaviors. OBJECTIVE: We aimed to develop and implement a theory-informed intervention intended to improve the movement behaviors and mental well-being of first-year postsecondary students. METHODS: The Intervention Mapping protocol was applied in the development and implementation of the intervention. Intervention Mapping entailed performing a needs assessment, determining the intervention outcomes, selecting theory- and evidence-based change methods and applications, preparing and producing intervention plans and materials, developing the implementation plan, and finally developing an evaluation plan. The Theoretical Domains Framework and the Behavior Change Wheel were also used in conjunction with the Intervention Mapping protocol to ensure a solid theoretical basis for the intervention. This protocol led to the development and implementation of a 6-week, theory-informed ParticipACTION app-based intervention aimed at helping first-year postsecondary students improve their movement behaviors and mental well-being. The developed app content provided students with information on each of the movement behaviors and behavioral strategies (ie, goal setting, action planning, monitoring, and coping planning). The use of Intervention Mapping allowed for the continuous involvement of various multidisciplinary partners and end users, ensuring that the intervention design and implementation was appropriate for the target audience. The feasibility, acceptability, and potential impact of the intervention will be examined in a subsequent proof-of-concept study at 2 Canadian university campuses. RESULTS: Participant recruitment occurred during September 2021, and the intervention was conducted from October to December 2021. The deadline for completion of the postintervention questionnaire by participants was mid-December 2021. The analysis of data examining the feasibility, acceptability, and potential impact of the intervention began in January 2022, with the publication of the proof-of-concept evaluation expected in 2023. CONCLUSIONS: Intervention Mapping with the Theoretical Domains Framework and Behavior Change Wheel was a useful approach to combine evidence and theoretical concepts to guide the design and implementation of a ParticipACTION app-based intervention targeting postsecondary students' movement behaviors and mental well-being. This process may serve as an example for other researchers developing multiple behavior change app-based interventions. Should the forthcoming evaluation demonstrate the intervention's acceptability, feasibility, and potential impact, the intervention may provide a scalable method of improving postsecondary students' movement behaviors and mental well-being.

The Associations between Meeting 24-Hour Movement Guidelines (24-HMG) and Mental Health in Adolescents-Cross Sectional Evidence from China.

(1) Background: This study determined the prevalence of adolescents that meet 24-HMGs alone and in combination, and their association with the risk of developing adolescent anxiety and depression. (2) Methods: Participants were drawn from 9420 K8 grade adolescents (age 14.53 ± 0.69 years; 54.78% boys) from the China Education Tracking Survey (CEPS) 2014-2015 tracking data. Data on depression and anxiety were collected from the results of the questionnaire in the CEPS for the adolescent mental health test. Compliance with the 24-HMG was defined as: physical activity time (PA) ≥ 60 min/day was defined as meeting the PA. Screen time (ST) ≤ 120 min/day was defined as meeting the ST. Adolescents aged 13 years achieved 9-11 h of sleep per night and adolescents aged 14-17 years achieved 8-10 h of sleep per night, defined as meeting sleep. Logistic regression models were used to examine the association between meeting and not meeting the recommendations and the risk of depression and anxiety in adolescents. (3) Results: Of the sample studied, 0.71% of adolescents met all three recommendations, 13.54% met two recommendations and 57.05% met one recommendation. Meeting sleep, meeting PA+ sleep, meeting ST + sleep, and meeting PA + ST + sleep were associated with a significantly lower risk of anxiety and depression in adolescents. Logistic regression results showed that differences in the effects of gender on the odds ratio (ORs) for depression and anxiety in adolescents were not significant. (4) Conclusions: This study determined the risk of developing depression and anxiety in adolescents who met the recommendations for 24-HMG alone and in combination. Overall, meeting more of the recommendations in the 24-HMGs was associated with lower anxiety and depression risk outcomes in adolescents. For boys, reducing the risk of depression and anxiety can be prioritised by meeting PA + ST + sleep, meeting ST + sleep and meeting sleep in the 24-HMGs. For girls, reducing the risk of depression and anxiety may be preferred by meeting PA + ST + sleep or meeting PA+ sleep and meeting sleep in 24-HMGs. However, only a small proportion of adolescents met all recommendations, highlighting the need to promote and support adherence to these behaviours.

Association Between 24-Hour Movement Guideline and Physical, Verbal, and Relational Forms of Bullying Among Chinese Adolescents.

The Canadian 24-Hour Movement Guidelines for Children and Youth recommends specific guidance in physical activity, screen time, and sleep duration. The current research will further explore potential exposures between healthy movement and being involved in a bullying incident as a bully or a victim in a representative sample of adolescents in China. A total of 67 821 Chinese students (response rate = 98.4%) were included in this study (mean age = 13.04 years). The results showed that meeting sleep recommendation only, meeting screen time recommendation only, and meeting both these two recommendations might be protective factors against being bullied or bullying others. Meeting moderate-to-vigorous physical activity (MVPA) recommendation only reported higher odds of being victims in all forms of bullying while meeting both MVPA and another combination of the guideline would relate to lower odds of being a bully and a bully-victim in all forms of bullying involvement.

Associations between meeting 24-hour movement guidelines and quality of life among children and adolescents with autism spectrum disorder.

BACKGROUND: The Canadian 24-hour movement behavior (24-HMB) guidelines suggest that a limited amount of screen time use, an adequate level of physical activity (PA), and sufficient sleep duration are beneficial for ensuring and optimizing the health and quality of life (QoL) of children and adolescents. However, this topic has yet to be examined for children and adolescents with autism spectrum disorder (ASD) specifically. The aim of this cross-sectional observational study was to examine the associations between meeting 24-HMB guidelines and several QoL-related indicators among a national sample of American children and adolescents with ASD. METHODS: Data were taken from the 2020 U.S. National Survey of Children's Health dataset. Participants (n = 956) aged 6-17 years and currently diagnosed with ASD were included. The exposure of interest was adherence to the 24-HMB guidelines. Outcomes were QoL indicators, including learning interest/curiosity, repeating grades, adaptive ability, victimization by bullying, and behavioral problems. Categorical variables were described with unweighted sample counts and weighted percentages. Age, sex, race, preterm birth status, medication, behavioral treatment, household poverty level, and the educational level of the primary caregivers were included as covariates. Odds ratio (OR) and 95% confidence interval (95%CI) were used to present the strength of association between adherence to 24-HMB guidelines and QoL-related indicators. RESULTS: Overall, 452 participants (45.34%) met 1 of the 3 recommendations, 216 (22.65%) met 2 recommendations, whereas only 39 participants (5.04%) met all 3 recommendations. Compared with meeting none of the recommendations, meeting both sleep duration and PA recommendations (OR = 3.92, 95%CI: 1.63-9.48, p < 0.001) or all 3 recommendations (OR = 2.11, 95%CI: 1.03-4.35, p = 0.04) was associated with higher odds of showing learning interest/curiosity. Meeting both screen time and PA recommendations (OR = 0.15, 95%CI: 0.04-0.61, p < 0.05) or both sleep duration and PA recommendations (OR = 0.24, 95%CI: 0.07-0.87, p < 0.05) was associated with lower odds of repeating any grades. With respect to adaptive ability, participants who met only the PA recommendation of the 24-HMB were less likely to have difficulties dressing or bathing (OR = 0.11, 95%CI: 0.02-0.66, p < 0.05) than those who did not. For participants who met all 3 recommendations (OR = 0.38, 95%CI: 0.15-0.99, p = 0.05), the odds of being victimized by bullying was lower. Participants who adhered to both sleep duration and PA recommendations were less likely to present with severe behavioral problems (OR = 0.17, 95%CI: 0.04-0.71, p < 0.05) than those who did not meet those guidelines. CONCLUSION: Significant associations were found between adhering to 24-HMB guidelines and selected QoL indicators. These findings highlight the importance of maintaining a healthy lifestyle as a key factor in promoting and preserving the QoL of children with ASD.

The Associations between Meeting 24-Hour Movement Guidelines (24-HMG) and Self-Rated Physical and Mental Health in Older Adults-Cross Sectional Evidence from China.

BACKGROUND: This study determined the prevalence of older adults (aged 60-80 years) meeting the Canadian 24-HMG alone and in combination, and their association with the self-rated physical health and mental health of older adults. METHODS: Participants were drawn from 4134 older adults aged 60-80 years (age, 67.37 ± 0.08 years; 46.87% male) from the China Health and Nutrition Survey (CHNS) 2015 database. Mental health and physical health scores were obtained based on self-rated mental health questionnaires and physical health of older adults. The criteria for meeting the 24-HMG were: physical activity time ≥ 150 min/week, sedentary time ≤ 480 min/day, screen time ≤ 180 min/day, sleep time 7-9 h (60-64 years) and sleep time 7-8 h (65 years and above). Logistic regression models were used to examine the association between meeting the 24-HMG guidelines number and category and older adults' self-rated mental and physical health. RESULTS: The proportion of older people meeting three of the 24-HMG guidelines was 1.16%, the proportion meeting two guidelines was 38.19% and the proportion meeting one guideline was 49.14%. The number of people meeting 24-HMG was closely related to the self-rated physical health and mental health of older people. The category meeting 24-HMG was closely related to the self-rated physical health and mental health of older people. CONCLUSIONS: Meeting more guidelines in the 24-HMG was strongly associated with older people's self-rated mental health and physical health. However, only a small proportion of older people met all the recommendations, highlighting the need to promote and support adherence to these movement behaviours.

Timing of 24-hour movement behaviours: implications for practice, policy and research. / Répartition des comportements en matière de mouvement sur 24 heures : implications en termes de pratique, de politiques et de recherche.

For health benefits, Canadians need to: move when it suits them; remove screens from bedrooms and limit screen use prior to bedtime; and adjust bedtime so that they can sleep the recommended amount. The 24-Hour Movement Guidelines Communication Toolkit has resources that can be used across settings to help Canadians optimize movement behaviours throughout the day.

Pour obtenir des bienfaits sur leur santé, les Canadiens et Canadiennes doivent : bouger au moment qui leur convient; retirer les écrans de leur chambre et limiter l'utilisation d'écrans avant de se coucher; adapter l'heure de leur coucher de manière à avoir le nombre d'heures de sommeil recommandé. La trousse de communication des Directives canadiennes en matière de mouvement sur 24 heures propose des ressources utilisables en fonction de diverses situations et divers milieux pour aider la population canadienne à optimiser ses comportements en matière de mouvement tout au long de la journée.

Association between 24-hour movement behaviors and health-related quality of life in children.

PURPOSE: To assess the associations between adherence to 24-hour movement behaviors guidelines and child general health and functional status measured by health-related quality of life. METHODS: The Longitudinal Study of Australian Children (2004-2016) a nationally representative sample with data available for children aged 2-15 years was used. Physical activity time, recreational screen time, and sleep time were calculated from time use diaries and classified as 'meeting guidelines' or 'not' based on the age-specific 24-h movement guidelines. Child general health and functional status were measured using the multidimensional Pediatric Quality of Life Inventory (PedsQL). Associations between meeting guidelines and PedsQL were assessed using linear mixed effects models. RESULTS: 8919 children were included. Each additional guideline met was associated with a 0.52 (95% confidence interval [CI] 0.39-0.65) increase in PedsQL total score. Compared with meeting no guidelines, the effect of meeting physical activity guidelines alone (ß = 0.93, 95% CI 0.42-1.44) was larger compared to meeting screen (ß = 0.66, 95% CI 0.06-1.27) or sleep time (ß = 0.47, 95% CI 0.04-0.89) guidelines alone. The highest increment was observed in meeting both screen time and physical activity guidelines (ß = 1.89, 95% CI 1.36-2.43). Associations were stronger in children from lower-income families (ß for meeting all versus none = 2.88, 95% CI 1.77-3.99) and children aged 14-15 years (ß = 4.44, 95% CI 2.49-6.40). CONCLUSIONS: The integration of screen time and physical activity guidelines is associated with the highest PedsQL improvement. The association between guidelines adherence and PedsQL appears stronger for adolescents and those from low-income families.

Post-secondary students' adherence to the Canadian 24-Hour Movement Guidelines for Adults: Results from the first deployment of the Canadian Campus Wellbeing Survey (CCWS). / Respect des Directives canadiennes en matière de mouvement sur 24 heures par les étudiants de niveau postsecondaire : résultats de la première enquête Bien-être sur les campus canadiens (BECC).

INTRODUCTION: New Canadian 24-Hour movement guidelines for adults recommend several hours of light physical activity each day, 150 minutes/week of moderate-to-vigorous physical activity (MVPA) including muscle strengthening activities at least twice a week, no more than 8 hours of sedentary time and 3 hours of recreational screen time each day, and 7 to 9 hours of sleep each night. This study examines post-secondary student adherence to the guidelines and its associations with sociodemographic factors and mental health. METHODS: We analyzed data from a sample of 20 090 post-secondary students in Canada who participated in the 2019-2020 Canadian Campus Wellbeing Survey (CCWS). Prevalence of meeting guidelines for physical activity, sedentary time, recreational screen time and sleep were examined. We conducted logistic regression to examine associations between meeting movement guidelines and sociodemographic factors and mental health outcomes. RESULTS: Only 9.9% of students (females 10.4%; males 9.2%) were currently achieving four components of the 24-hour movement guidelines. Respondents most commonly adhered to MVPA (61.1%) and sleep (59.7%) guidelines. Adherence to sedentary and screen time guidelines was lower (56.3% and 36.2%, respectively). Sociodemographic factors associated with higher odds of meeting the guidelines included being female, older age, self-identifying as White, and living at high socioeconomic status. Students who reported higher psychological well-being were more likely to meet the guidelines. DISCUSSION: Overall adherence to the new guidelines is low among post-secondary students in Canada. The CCWS provides a mechanism for monitoring the dissemination and implementation of the new Canadian 24-hour movement guidelines for adults.

Adherence to 24-Hour Movement Guidelines among Spanish Adolescents: Differences between Boys and Girls.

BACKGROUND: The 24-Hour Movement Guidelines for adolescents recommend ≥60 min/day of moderate-to-vigorous physical activity (PA), ≤ 2 h/day of screen time, and 8-10 h/day of sleep. Since little information is available on the 24-Hour Movement Guidelines in Spanish adolescents, this study aims to estimate the proportion of Spanish adolescents meeting individual and combinations of these 24-Hour Movement Guidelines. Moreover, another aim of this study is to examine gender differences in compliance with 24-Hour Movement Guidelines. METHODS: A final sample of 1465 Spanish adolescents (44.50% girls; 13.08 ± 0.86) participated in this cross-sectional study. The 24-Hour Movement Guidelines were measured during weekdays and the weekend days by self-reported questionnaires. RESULTS: Although most adolescents met sleep duration guidelines (81.3%), only 38% and 15.8% met physical activity and screen time guidelines, respectively. Only 5.4% of these adolescents met all three 24-Hour Movement Guidelines, whereas 10.2% of this sample did not meet any of these guidelines. Although boys reported greater compliance with physical activity recommendations and girls with screen time recommendations, no significant gender differences were found in the compliance of all three 24-Hour Movement Guidelines. CONCLUSION: Given that 94.4% of Spanish adolescents did not meet 24-Hour Movement Guidelines, promoting all these three movement behaviours in both boys and girls is an urgent public health priority.

Adherence to the 24-hour movement guidelines and adiposity in a cohort of at risk youth: A longitudinal analysis.

BACKGROUND: The 24-hour movement guidelines provide recommendations for physical activity, screen time and sleep duration for children. OBJECTIVES: Describe adherence to the guidelines and their cross-sectional and longitudinal associations with adiposity from childhood to adolescence. METHODS: Data are from the QUALITY Cohort. Children were followed at 8 to 10 years (childhood; n = 630), 10 to 12 years (early adolescence; n = 564) and 15 to 17 years (adolescence; n = 377). Physical activity, screen time, and sleep duration were measured by accelerometry and questionnaires. Body mass index z-scores (zBMI), waist circumference, waist-to-height ratio and percent body fat were based on clinical measurements. Multiple linear regressions estimated associations. RESULTS: In childhood, early adolescence and adolescence, 14%, 6%, and 0% of participants met the 24-hour movement guidelines, respectively. Meeting fewer guideline components was cross-sectionally associated with higher adiposity at each visit. Meeting fewer guideline components in childhood was longitudinally associated with higher adiposity at later visits. For example, those meeting none of the guideline components (vs all) in childhood had a 1.66 SD (95% CI: 0.42, 2.89) higher zBMI in early adolescence. CONCLUSION: Few participants met the guidelines. Not meeting the guidelines in childhood is associated with higher adiposity 2 and 7 years later. Interventions are needed to increase adherence to the 24-hour movement guidelines across childhood and adolescence.

Knowledge translation of the Canadian 24-Hour Movement Guidelines for Adults aged 18-64 years and Adults aged 65 years or older: a collaborative movement guideline knowledge translation process.

Establishing a step-by-step process that provides practitioners with a blueprint for translating movement guidelines into action stands to optimize the investment in guideline development, improve guideline promotion and uptake, and ultimately enhance population health. The purpose of this paper is to describe how the Knowledge-to-Action framework and integrated knowledge translation were operationalized to systematically inform our knowledge translation (KT) efforts for the Canadian 24-Hour Movement Guidelines for Adults aged 18-64 years and Adults aged 65 years or older. In October 2018, the need for a KT Process, operating in tandem with the Guideline Development Process, led to the establishment of a KT team with a specific structure and terms of reference. The KT team collaboratively agreed on decision-making principles prior to selecting target audiences to focus their efforts. We undertook formative research to assess the local context and determinants of guideline dissemination and implementation efforts among target audiences. Plans for the subsequent steps and research are outlined. We highlight recommendations and lessons learned for applying the process in other settings. Novelty We outline a collaborative and systematic process and research program for the knowledge translation of movement guidelines. This paper provides an innovative and replicable blueprint to optimize future movement guideline knowledge translation efforts.
