BACKGROUND: The distribution of time across physical activity, sedentary behaviors, and sleep appears to be essential for the management of obesity. However, the impact of reallocating time among these behaviors, collectively known as 24-h movement behaviors, remains underexplored. OBJECTIVE: This study examines the theoretical effects of reallocating time between 24-h movement behaviors on obesity indicators across different age groups. METHODS: We performed a pooled data meta-analysis of 9818 participants from 11 observational and experimental studies. To estimate the time spent in movement behaviors, we reprocessed and harmonized individual-level raw accelerometer-derived data. Isotemporal substitution models estimated theoretical changes in body mass index (BMI) and waist circumference (WC) associated with time reallocation between movement behaviors. We performed the analysis separately for children, adolescents, adults, and older adults. RESULTS: Even minor reallocations of 10 min led to significant changes in obesity indicators, with pronounced effects observed when 30 min were reallocated. The most substantial adverse effects on BMI and WC occurred when moderate-to-vigorous physical activity (MVPA) was reallocated to other movement behaviors. For 30-min reallocations, the largest increase in BMI (or BMI z-score for children) occurred when MVPA was reallocated to light-intensity physical activity (LPA) in children (0.26 units, 95% confidence interval [CI] 0.15, 0.37) and to sedentary behavior (SB) in adults (0.72 kg/m2, 95% CI 0.47, 0.96) and older adults (0.73 kg/m2, 95% CI 0.59, 0.87). The largest increase in WC was observed when MVPA was substituted with LPA in adults (2.66 cm, 95% CI 1.42, 3.90) and with SB in older adults (2.43 cm, 95% CI 2.07, 2.79). Conversely, the highest magnitude of the decrease in obesity indicators was observed when SB was substituted with MVPA. Specifically, substituting 30 min of SB with MVPA was associated with a decrease in BMI z-score by - 0.15 units (95% CI - 0.21, - 0.10) in children and lower BMI by - 0.56 kg/m2 (95% CI - 0.74, - 0.39) in adults and by - 0.52 kg/m2 (95% CI - 0.61, - 0.43) in older adults. Reallocating time away from sleep and LPA showed several significant changes but lacked a consistent pattern. While the predicted changes in obesity indicators were generally consistent across age groups, inconsistent findings were observed in adolescents, particularly for reallocations between MVPA and other behaviors. CONCLUSIONS: This investigation emphasizes the crucial role of MVPA in mitigating obesity risk across the lifespan, and the benefit of substituting SB with low-intensity movement behaviors. The distinct patterns observed in adolescents suggest a need for age-specific lifestyle interventions to effectively address obesity. Emphasizing manageable shifts, such as 10-min reallocations, could have significant public health implications, promoting sustainable lifestyle changes that accommodate individuals with diverse needs, including those with severe obesity.

BACKGROUND: The actions required to achieve higher-quality and harmonised global surveillance of child and adolescent movement behaviours (physical activity, sedentary behaviour including screen time, sleep) are unclear. OBJECTIVE: To identify how to improve surveillance of movement behaviours, from the perspective of experts. METHODS: This Delphi Study involved 62 experts from the SUNRISE International Study of Movement Behaviours in the Early Years and Active Healthy Kids Global Alliance (AHKGA). Two survey rounds were used, with items categorised under: (1) funding, (2) capacity building, (3) methods, and (4) other issues (e.g., policymaker awareness of relevant WHO Guidelines and Strategies). Expert participants ranked 40 items on a five-point Likert scale from 'extremely' to 'not at all' important. Consensus was defined as > 70% rating of 'extremely' or 'very' important. RESULTS: We received 62 responses to round 1 of the survey and 59 to round 2. There was consensus for most items. The two highest rated round 2 items in each category were the following; for funding (1) it was greater funding for surveillance and public funding of surveillance; for capacity building (2) it was increased human capacity for surveillance (e.g. knowledge, skills) and regional or global partnerships to support national surveillance; for methods (3) it was standard protocols for surveillance measures and improved measurement method for screen time; and for other issues (4) it was greater awareness of physical activity guidelines and strategies from WHO and greater awareness of the importance of surveillance for NCD prevention. We generally found no significant differences in priorities between low-middle-income (n = 29) and high-income countries (n = 30) or between SUNRISE (n = 20), AHKGA (n = 26) or both (n = 13) initiatives. There was a lack of agreement on using private funding for surveillance or surveillance research. CONCLUSIONS: This study provides a prioritised and international consensus list of actions required to improve surveillance of movement behaviours in children and adolescents globally.

PURPOSE: The International Study of Movement Behaviors in the Early Years (SUNRISE) was conducted in Tunisia to assess the proportion of preschoolers who met the World Health Organization guidelines for physical activity, sedentary behavior, and sleep. The study also evaluated the feasibility of the methods for the SUNRISE study. METHODS: Five kindergartens were recruited from urban and rural areas in Tunisia. Physical activity and sleep duration were assessed using a waist-worn ActiGraph. Screen time and sleep quality were assessed via an interview-administered parent questionnaire. The NIH Toolbox was used. RESULTS: A total of 112 preschoolers were assessed (50 boys, age = 4.1 [0.58]). Only 18% of children met all recommendations of the World Health Organization guidelines, while 53% met the sedentary screen time (in minutes per day), and 41% met physical activity recommendation (in minutes per day). Eighty-one percent of children met the sleep duration recommendation (in minutes per day). There was good compliance with the ActiGraph protocol. CONCLUSIONS: This pilot study provided important insights into the feasibility of the study and the movement behaviors of Tunisian preschool children. The results suggest there is a need to promote healthy levels of physical activity and sedentary screen time in children, which should be a priority in public health initiatives, including preschool curricula, in Tunisia.

BACKGROUND: Adolescents' movement behaviours (MB) vary between schooldays and weekends, potentially impacting health-related quality of life (HRQoL) and well-being. This study aimed to identify transitions between 24-h MB profiles on schooldays and weekends and examine their associations with HRQoL and well-being. METHODS: This is a cross-sectional study of 1070 Czech adolescents (average age: 13.8 years and standard deviation: 2.2 years; 56% girls). Participants wore accelerometers for 7 consecutive days to assess physical activity (PA) of different intensities, sedentary behaviour (SB) and sleep. A subsample of 451 participants provided data on HRQoL, which was measured using the Paediatric Quality of Life Inventory, and 484 provided valid well-being data measured with the 5-item World Health Organisation Well-Being Index. Latent transition analysis was used on the MB variables to identify transitions across MB profiles, and linear regression was used to examine associations between transitions and HRQoL or well-being. RESULTS: Four MB profiles were identified: Excellent (high PA, low SB and high sleep duration), Good (average MB values), Fair (below-average PA and sleep, above-average SB) and Poor (low PA and sleep, high SB). Most adolescents transitioned to less favourable profiles on weekends. Those remaining in the Excellent profile had higher HRQoL than those transitioning to less favourable profiles. Transitions to the Poor profile were associated with the lowest HRQoL and well-being scores. CONCLUSION: This study underscores the dynamic nature of adolescents' MB and the importance of consistent, healthy routines. Interventions optimizing 24-h MB throughout the week and especially on weekends may enhance adolescent HRQoL and well-being, but further evidence from longitudinal and intervention studies is needed. SUMMARY: We observed a contrast in 24-h MB between schooldays and weekends: 29.7% of adolescents were in the Excellent on schooldays, but only 5.8% did so on weekends, while the prevalence of the Poor profile rose from 1.6% on schooldays to 27.7% on weekends. Adolescents who maintained the Excellent profile across the whole week recorded the highest scores for HRQoL and well-being. Moving into the Poor profile on weekend was associated with about 9 points poorer HRQoL and 14 points lower well-being, compared with peers who remained in the Excellent profile. Behaviour change strategies should target the entire week to preserve PA, reduce SB and protect sleep.

BACKGROUND: Preservation of mobility independence is a primary goal in older adults with physical frailty and sarcopenia (PF&S). Interventions based on the combination of physical activity (PA) and nutritional counselling have been indicated as strategies for the management of this condition, although their effectiveness is not confirmed in all investigations. A possible explanation for this uncertain scenario relies in the impact of the adherence to PA interventions. Hence, the present study investigated the impact of the adherence to PA sessions on the incidence of mobility disability in older adults with PF&S. METHODS: This is a secondary analysis of an evaluator blinded, randomised controlled trial, developed in 16 clinical sites across 11 European countries, from January 2016 to 31 October 2019. Participants were community-dwelling older adults (70+ years) with PF&S enrolled in the SPRINTT trial (NCT02582138). PF&S was operationalised as having a total score from 3 to 9 on the short physical performance battery (SPPB), low appendicular lean mass and ability to complete the 400-m walk test in < 15 min. Data from participants allocated to a multicomponent intervention (PA with technological support plus nutritional counselling) and a healthy ageing lifestyle education programme (control group) were analysed. Adherence to PA was assessed based on the number of weekly sessions attended. According to recommendations of the American College of Sports Medicine, adherence was categorised as below recommendations (< 2 sessions/week, BR), meeting recommendations (2-3 sessions/week, MR), and above recommendations (> 3 sessions/week, AR). The primary outcome was incident mobility disability, operationalised as incident inability to complete the 400-m walk test in < 15 min during up to 36 months of follow-up. RESULTS: Data of 1444 participants (mean age 79.3 years, 72.6% women) were analysed. In those with SPPB scores of 3-7, MR and AR groups had lower risk of mobility disability compared with controls [MR HR (95% CI): 0.57 (0.41-0.78), p = 0.001; AR HR (95% CI): 0.33 (0.23-0.46), p < 0.001] and BR groups [MR: HR (95% CI): 0.48 (0.34-0.69), p < 0.001; AR: HR (95% CI): 0.27 (0.18-0.38), p < 0.001] in a dose-dependent manner. In those with SPPB scores of 8 or 9, the BR group had a higher risk of mobility disability than controls. MR and AR groups had a lower risk of mobility disability than the BR group. CONCLUSIONS: In older adults with PF&S, adherence to PA recommendations is associated with lower incidence of mobility disability. This benefit depends on the degree of adherence as well as baseline physical performance. TRIAL REGISTRATION: ClinicalTrials.gov NCT02582138.

Promoting healthy aging through physical activity (PA) is crucial as the global population grows older. Traditional interventions often fail to engage older adults, underlining the need for personalized, timely approaches. Smartphone-delivered PA interventions can offer personalized support during opportune moments for behavioral change. The current study examined whether the receptivity of inactive older adults influences compliance with mHealth walking suggestions after inactivity, and explored their experiences with it. Thirty healthy older adults (mean age 73.9 years) participated in the study and answered event-based EMA questionnaires via HealthReact after each 30-minute inactivity period. Emotions, physical complaints, intention, self-efficacy, perceived walking, and environmental permissiveness were assessed. Walking suggestions followed each EMA, and semi-structured interviews were conducted post-study. Multilevel logistic regressions in R were applied, and qualitative data were thematically analyzed using NVivo. Results show that higher intention, self-efficacy, and environmental permissiveness positively correlated with compliance, while higher perceived walking negatively correlated. Participants generally found the suggestions motivating and well-timed, but some reported increased alertness and pressure. Consequently, tailoring interventions to individual needs and targeting receptive moments can enhance compliance and promote healthier aging through increased PA. Future mobile interventions should consider self-efficacy, intention, prior activity, and environmental conditions to improve effectiveness.

Obezita a diabetes mellitus 2. typu (DM2T) sú významnými rizikovými faktormi rozvoja kognitívnej dysfunkcie a neurodegeneratívnych ochorení. Ich spoločný patofyziologický základ zahŕňa inzulínovú rezistenciu, chronický subklinický systémový zápal a neurozápal, poruchy mikrobiómu, hormonálnu dysreguláciu a štrukturálne zmeny mozgu. Tieto faktory vedú k zhoršeniu pamäte, exekutívnych funkcií a k akcelerácii neurodegenerácie. Pozitívne účinky úpravy životného štýlu – vrátane zníženia telesnej hmotnosti, zvýšenia fyzickej aktivity a úpravy výživy a stravovacích návykov – sa prejavujú zlepšením inzulínovej senzitivity v mozgu, zvýšením neurotrofických faktorov, redukciou systémového zápalu a neurozápalu a zlepšením metabolizmu. Kombinácia behaviorálnych a farmakologických intervencií môže spomaliť kognitívny pokles a znížiť riziko demencie u populácie s obezitou a poruchou metabolizmu glukózy.

Obesity and type 2 diabetes (T2D) are important risk factors for the development of cognitive dysfunction and neurodegenerative diseases. Their common pathophysiological substrate includes insulin resistance, chronic subclinical systemic inflammation, neuroinflammation, shifts in the intestinal microbiome composition, hormonal dysregulation, and structural changes of the brain. These factors lead to impaired memory, executive functions, and accelerated neurodegeneration. The positive effects of lifestyle modifications — including weight loss, increased physical activity, and improved dietary composition — are manifested by improved insulin sensitivity in the brain, increased neurotrophic factors, reduced systemic inflammation and neuroinflammation, and improved metabolism. A combination of behavioral and pharmacological interventions may slow cognitive decline and reduce the risk of dementia in patients with obesity, prediabetes and T2D.

In this manuscript, we highlight the evolutionary origins of mitochondria from bacterial endosymbionts and explore their contributions to health, energy metabolism, and neural-immune communication. Mitochondrial adaptability and the roles played by these organelles in promoting oxygen-dependent ATP production provide critical regulation of cognition, motivation, and inflammation. Hypoxia has been identified as an important initiator of inflammation, neurodegeneration, and mitochondrial dysfunction, emphasizing the overall importance of oxygen homeostasis to health and well-being. The Behavior, Exercise, Relaxation, and Nutrition framework highlights these observations as tools that can be used to optimize mitochondrial efficiency. Interestingly, mitochondrial dysfunction may also be linked to psychiatric disorders (e.g., schizophrenia), a hypothesis that focuses on energy dynamics, a proposal that may extend our understanding of these disorders beyond traditional neurotransmitter-focused concepts. Collectively, these perspectives underscore the critical contributions of mitochondria to health and disease and offer a novel framework that may help to explain the connections featured in mind-body medicine.

Improving the quality of the most basic health behavior among youth may contribute to short-term body composition management with long-term implications for noncommunicable disease regression. This investigation aimed to assess the impact of primary school physical activity (PA), dietary, or dual approach interventions on pupils' body weight (BW) and body mass index (BMI). A systematic review and meta-analysis was completed following a study protocol and a trial registration (PROSPERO: CRD4202347770) with the PRISMA approach. Publications in English or German were included with school-based randomized controlled trials on diet and/or PA. Pupils of primary schools (aged 5-10) with no major nutritional deficiency or unstable health condition were included. The Boolean search strategy revealed a total of 9479 articles, qualifying 39 studies with 20 462 pupils (including 10 211 girls and 10 251 boys) for quantitative synthesis. The interventions were mostly PA (n = 31), several were dietary (n = 6), and some were dual approach (n = 5). Random effects meta-analyses revealed PA intervention (n = 20) to have an effect size of +0.07 kg (95% CI: -0.01 to 0.15) and -0.12 kg/m2 (95% CI: -0.23 to -0.01). Low statistical heterogeneity was found for BW (I2 = 0%; P = 1.000) and BMI (I2 = 0%; P = .9688), respectively. The findings indicate a scarcity of top-quality scientific research performed on healthy diet for body weight management in primary schools. PA intervention for elementary school pupils provides support for a healthier body composition profile amidst the current world health crisis.

BACKGROUND: The development of child's lifestyle occurs within regular 24-hour movement patterns under the guidance of parents. Accelerometer-based monitoring allows for the capture of these 24-hour movement patterns of behaviour. Therefore, the aim of this study was to reveal whether active participation in organised physical activity (OPA) contributed to the achievement of the World Health Organization's (WHO) 24-hour movement behaviour guidelines (24-hMBGS) among 3-10-year-old children, considering the influence of parents' movement behaviour and families' material background. METHODS: The 24-hour movement behaviour (24-hMB) of 348 child-parent pairs (with at least one parent) was continuously monitored for 7 days via ActiGraph accelerometers placed on the non-dominant wrist. Children's adherence to the WHO's 24-hMBGS was analysed using logistic regression analysis. The socioeconomic status (SES) of families was measured using the Family Affluence Scale. Body mass level was determined according to body mass index gender- and age-specific WHO reference data. Univariate analysis of variance/Pearson's chi-square test was used to test differences in sedentary behaviour duration/excess body weight between active participants and non-participants in OPA. RESULTS: Active 3-10-year-old participants in OPA, compared to non-participants, were significantly more likely to meet at least two of the 24-hMBGS (77.7% vs. 66.4%, p = 0.008), had significantly shorter daily sedentary time (by 30 min per day, p = 0.001), and a significantly lower prevalence of excessive body weight (10.26% vs. 24.87% p < 0.001). Engaging in OPA significantly (p < 0.01) helped 3-10-year-old children achieve at least two of the 24-hMBGS, regardless of their gender, age, excess body weight, or family SES. In addition, a mother's non-excessive body weight and achievement of at least two of the WHO's 24-hMBGS significantly (p < 0.05) contributed to children attaining at least two of the WHO's 24-hMBGS. CONCLUSIONS: Even in young children, active participation in OPA tend to contribute to a healthier lifestyle profile, characterised by shorter sedentary behaviour and lower excess body weight, with a significant influence from the mother's movement behaviour.
