BACKGROUND: Questionnaires remain the most feasible method for large-scale physical activity (PA) surveillance. However, previous systematic reviews concluded that existing questionnaires had unsatisfactory psychometric properties. OBJECTIVES: This systematic review aimed to summarize and evaluate the measurement properties of self- and proxy-reported physical activity (PA) measures in children and adolescents published between 2018 and July 2024, thereby updating a previous review. This review also aimed to recommend the best available questionnaire(s) for young children (age < 6 years), children (age ≥ 6 to < 12 years), and adolescents (age ≥ 12 to < 18 years). METHODS: The COnsensus-based Standards for the Selection of Health Measurement INstruments (COSMIN) Guidelines for Systematic Reviews of Patient-Reported Outcome Measures were followed for conducting and reporting this systematic review. PubMed, EMBASE, and SPORTDiscus databases were searched for papers published between 2018 and July 2024. The peer-reviewed papers were included if published in Arabic, Chinese, Czech, English, French, Hindi, Nepali, Portuguese, Spanish, Swedish or Thai and assessed at least one of the measurement properties of self- or proxy-reported PA measures in young children, children, and adolescents. Papers were excluded if they measured PA with interview or diary or reported construct validity against non-PA measures (e.g., body mass index). The results of studies from the previous systematic review that reported test-retest reliability and construct validity of the questionnaires included in this systematic review were added to the pooled qualitative analyses and meta-analyses. RESULTS: A total of 106 papers were included which reported 177 studies related to content validity (n = 31), construct validity including hypotheses testing (n = 80), test-retest reliability (n = 65), and responsiveness (n = 1) of 71 questionnaires. None of the included questionnaires met the COSMIN criteria for sufficient content validity. Questionnaires with satisfactory construct validity (correlation r ≥ 0.4) were found in young children (n = 2; e.g., the Outdoor Playtime Recall), children (n = 2; e.g., Self-rating Scale of Physical Activity Intensity for Preschool Children), and adolescents (n = 8; e.g., the Spanish version of Physical Activity Unit 7 Item Screener, the Czech version of Youth Activity Profile). Questionnaires with sufficient test-retest reliability (≥ 0.7) were found in young children (n = 2; e.g., the Movement Behaviour Questionnaire for Baby and Children), children (n = 3; e.g., Diet and Physical Activity Behaviors in the Feel4Diabetes Study), and adolescents (n = 5; e.g., the 24-Hour Movement Behavior Questionnaire). The Physical Activity Questionnaire for older Children and Adolescents had sufficient test-retest reliability based on pooled qualitative analysis and meta-analyses. The best available questionnaires were the Outdoor Playtime Recall (for young children) and the Physical Activity Questionnaire for Older Children and Adolescents for children and adolescents. CONCLUSION: This systematic review update did not identify a PA questionnaire that met COSMIN standards for both construct validity and test-retest reliability, partly due to the low methodological quality of the studies. Researchers should improve the methodological rigor of future psychometric studies, particularly for content validity, by adopting standardized guidelines (e.g., COSMIN). We also recommend: (1) using comparator tools that have demonstrated reliable measurement properties in populations similar to the target group; (2) formulating hypotheses in advance to confirm construct validity; (3) selecting appropriate intervals between test and retest and ensuring consistent test conditions; and (4) providing evidence of PA stability between test and retest. Lastly, when developing questionnaires to measure total PA, researchers should include all relevant domains of PA and assess their relevance during the content validation process.

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: To design effective tailored interventions to promote physical activity (PA) among older adults, insights are needed into the contexts in which older adults engage in PA and their affective and physical experiences. Sensor-triggered event-based ecological momentary assessment (EMA) is an innovative method for capturing real-life contexts, as well as affective and physical states, during or immediately after specific events, such as PA. This study aimed to (1) describe the physical and social contexts, and the affective and physical states during PA among older adults, (2) evaluate how these constructs fluctuate during PA episodes, and (3) describe affective states during PA according to the context. METHODS: An intensive longitudinal sensor-triggered event-based EMA study was conducted with 92 Belgian older adults (65 + years). During seven days, participants were monitored using a Fitbit, which triggered a smartphone-based questionnaire on the event-based EMA platform 'HealthReact' after a five-minute walk. Participants reported on contexts and affective (positive/negative valence) and physical states (pain and fatigue) during the PA event. Descriptive statistics and generalized mixed models were used for data analysis. RESULTS: Older adults predominantly engaged in daily physical activities, such as walking for transport, leisure walking, and gardening, rather than structured exercise. They consistently reported high positive affect, low negative affect, and minimal physical complaints during PA. Furthermore, older adults mainly engage in physical activities alone, particularly in outdoor settings. Variations in contexts, affect, and fatigue were mostly driven by within-subject differences. The model showed significant differences across times of day, with negative affect being highest in the evening and fatigue lowest in the morning. Additionally, the physical and social context influenced negative affect (but not positive affect), with outdoor activities performed alone and indoor activities performed with others being associated with lower negative affect. CONCLUSIONS: While these findings could enhance the effectiveness of tailored PA interventions, it remains unclear whether the observed affective and physical states are causes or effects of PA, and whether the contexts in which the activities were performed align with older adults' preferences. Further research is needed to explore these relationships and to better understand older adults' preferred PA contexts.

Background/Objectives: Elevated body temperature is a well-established biomarker of infection, increased disease risk, and adverse health outcomes. However, the relationship between resting body temperature and long-term survival in older individuals is complex. Emerging evidence suggests that higher basal body temperature is associated with reduced survival and accelerated aging in non-obese older adults. This study aimed to compare body temperatures across different age groups in hospitalized older adults. Methods: Data were retrospectively collected from 367 physically healthy residents of a mental health center. Longitudinal data from 142 individuals (68 men and 74 women), aged 45 to 70 years and monitored continuously over 25 years, were compared with cross-sectional data from 225 individuals (113 men and 112 women) who underwent periodic clinical examinations with temperature measurements. The cross-sectional sample was stratified into four survival categories. Resting oral temperatures were measured under clinical conditions to ensure protocol consistency. Age-related changes in both sexes were evaluated using standard regression analysis, Student's t-tests, ANOVA, and Generalized Linear Models. Results: Longitudinal analysis revealed an increase in body temperature with age among women, while cross-sectional analysis showed that long-lived residents generally had lower body temperatures compared to their shorter-lived counterparts. Conclusions: These findings support the hypothesis that lower lifetime steady-state body temperature is associated with greater longevity in physically healthy older adults. However, further research is needed to determine whether the lower body temperature observed in long-lived individuals is linked to specific health advantages, such as enhanced immune function, absence of detrimental factors or diseases, or a reduced metabolic rate potentially influenced by caloric restriction.

PURPOSE: Clinical guidelines call for the inclusion of exercise interventions in every patient's dialysis session, but these recommendations are rarely adopted. Healthcare providers play a key role in this. Therefore, the aim of this study was to explore how healthcare providers perceive the benefits, risks and barriers of intradialytic exercise (IDE). METHODS: We conducted 21 individual, semi-structured interviews with 11 nurses, 5 nephrologists, 3 training assistants and 2 managers from two dialysis centres in Slovakia. Verbatim transcripts of digitally recorded interviews were thematically analysed using MAXQDA®. RESULTS: Participants reported the benefits of IDE as improvements in patients' physical and psychosocial functioning, independence and self-efficacy, clinical profile and quality of therapy. As risks of IDE, they most frequently reported exercise-related damage to vascular access, insufficient individualization of training and musculoskeletal injuries. The presence of psychological problems among patients was reported as a major barrier for initiating and maintaining patients' exercise. Other reported barriers included limitations in financial and personnel resources of haemodialysis care. CONCLUSIONS: Safe and sustainable implementation of IDE, which might improve a patient's well-being, need to be prescribed in alignment with the patient's clinical profile, be delivered individually according to the patient's characteristics and requires adjustments in the available resources.

OBJECTIVE: This study aims to assess the suitability of Fitbit devices for real-time physical activity (PA) and sedentary behaviour (SB) monitoring in the context of just-in-time adaptive interventions (JITAIs) and event-based ecological momentary assessment (EMA) studies. METHODS: Thirty-seven adults (18-65 years) and 32 older adults (65+) from Belgium and the Czech Republic wore four devices simultaneously for 3 days: two Fitbit models on the wrist, an ActiGraph GT3X+ at the hip and an ActivPAL at the thigh. Accuracy measures included mean (absolute) error and mean (absolute) percentage error. Concurrent validity was assessed using Lin's concordance correlation coefficient and Bland-Altman analyses. Fitbit's sensitivity and specificity for detecting stepping events across different thresholds and durations were calculated compared to ActiGraph, while ROC curve analyses identified optimal Fitbit thresholds for detecting sedentary events according to ActivPAL. RESULTS: Fitbits demonstrated validity in measuring steps on a short time scale compared to ActiGraph. Except for stepping above 120 steps/min in older adults, both Fitbit models detected stepping bouts in adults and older adults with sensitivities and specificities exceeding 87% and 97%, respectively. Optimal cut-off values for identifying prolonged sitting bouts achieved sensitivities and specificities greater than 93% and 89%, respectively. CONCLUSIONS: This study provides practical insights into using Fitbit devices in JITAIs and event-based EMA studies among adults and older adults. Fitbits' reasonable accuracy in detecting short bouts of stepping and SB makes them suitable for triggering JITAI prompts or EMA questionnaires following a PA or SB event of interest.
BACKGROUND: Interventions to improve physical activity (PA) among adolescents continue to be a public health priority. To promote PA more effectively, we need to identify the main factors contributing to (not) engagement in PA in the perspective of adolescents themselves. Thus, we explored the barriers and enablers for sufficient moderate-to-vigorous physical activity (MVPA) in adolescents from their point of view. METHODS: We used qualitative data collected as part of the international Health Behaviour in School-Aged Children study. We obtained data from 14-17 years old adolescents from the first year of Slovak high school. We conducted 11 online, semi-structured individual and group interviews with 24 participants in total (7 boys; mean age = 15.17, SD = 0.87) in Slovakia. We analysed the data using consensual qualitative research and thematic analysis. RESULTS: In the statements of adolescents, four main themes were identified regarding factors contributing to (not) engagement in PA among adolescents. 'Myself as a source' represents the importance of adolescents' own efforts, knowledge, physical predispositions and PA experience. 'How PA can be done' represents school as an opportunity for PA, and PA teachers and sports coaches as specialists who can create an enabling environment for sports. 'Others as a source' represents the social circle that can set a positive sports example and can encourage adolescent's efforts in PA. 'Factors outside' represents other factors that can inspire adolescents, e.g. by giving them a comfortable space and time to exercise, or can be a barrier to PA. CONCLUSION: The potential factors that include adolescents' perspectives can be more leveraged in designing supportive, inclusive, enjoyable, and skills-appropriate PA programmes.
Exergames are defined as digital games that require bodily movements to play, stimulating an active gaming experience to function as a form of physical activity (PA). The players interact with the game through whole-body movements improving energy expenditure. Exergames may be effective in improving physical and psychological aspects of children and adolescents with obesity. In this narrative review, we synthesized the current evidence regarding the role of exergames in modifying body composition and weight and in promoting changes in sedentary behavior to define the benefits of active video games as useful tools for fighting sedentarism and to outline the future directions of exergaming as a supplementation exercise rather than a replacement in educational programs for pediatric obesity. Data from the literature indicate that exergames may offer an interesting impact on childhood obesity and may be considered a potential strategy for controlling weight gain and body composition, promote PA, and decrease time spent on sedentary behavior in children and adolescents with obesity. However, exergame use also has some limits, such as children's poor self-regulation and poor structuring of exergame use. Therefore, a prudent approach should be maintained, and additional high-quality research is needed to determine if exergames can be effectively used in the treatment of childhood obesity and if new digital media, as a supplementation of exercise rather than a replacement, could be considered to combat sedentary behavior in educational programs for pediatric obesity prevention.

BACKGROUND/OBJECTIVE: The second edition of the Czech Republic's Report Card on Physical Activity for Children and Youth was released in 2022. This paper describes the development of the Report Card and presents a comprehensive summary of the main findings. METHODS: The multi-level search strategy was developed by the national expert panel to identify the available sources that provide data related to the physical activity of Czech children and adolescents. The data were used to assign grades to ten core and two additional indicators. RESULTS: A total of 28 sources provided data that allowed grades to be assigned to 11 out of the 12 indicators. Grade B was assigned to six indicators (School: B+, Community and Environment: B, Organized Sport and Physical Activity: B-, Active Transportation: B-, Family and Peers: B-, Sleep: B-), grade C to three indicators (Overall Physical Activity: C+, Active Play: C, Physical Literacy: C), and grade D to two indicators (Government: D+, Sedentary Behaviors: D). No grade for the "Physical Fitness" indicator could be assigned due to a lack of data collected in the reference period 2018-2019. CONCLUSIONS: Although the family, school, and built environment provided a variety of opportunities to be physically active, a high proportion of children and adolescents did not meet the current physical activity guideline and were exposed to excessive sedentary behavior. A multisectoral and multidisciplinary response is required to reduce the health and economic burden of physical inactivity and excessive sedentary behavior among Czech children and adolescents.

BACKGROUND: Lockdowns amid the COVID-19 pandemic drastically reduced the possibility of undertaking physical activity (PA) in gyms, swimming pools, or work-related PA, e.g., active commuting. However, the stay-at-home order could have reduced PA the most, i.e., the ban of unnecessary outdoor activities. It affected free walking, running, skiing, active tourism, etc. It is, therefore, crucial to estimate how the stay-at-home order affected PA. We estimated how the stay-at-home order affected perceived PA and sedentary behavior compared to the pre-pandemic time in Poland. METHODS: We used a self-reported International Physical Activity Questionnaire-Long Form (IPAQ-LF) to estimate the time (minutes per day) of vigorous and moderate PA and walking and sitting time. RESULTS: We gathered data from 320 Polish participants. Bayesian approaches, including t-test and Bayesian correlations, were used to find differences and correlations between PA before and during the stay-at-home lockdown. Our data supported the hypotheses that vigorous PA, as well as walking, declined during the lockdown. Surprisingly, our data did not support the hypothesis that moderate physical activity was reduced. We found that moderate PA during lockdown increased compared to the pre-lockdown PA. As hypothesized, our data strongly evinced that sitting time inclined during the lockdown. PA decline was not correlated with the available living space. People who had access to gardens did not demonstrate a higher PA level than those without. DISCUSSION: Walking and sitting time have drastically changed during the stay-at-home lockdown, decreasing and increasing, respectively. Given results from studies focusing on lockdowns without the stay-at-home restriction, it may be assumed that letting people go outside is crucial in keeping them more active and less sedentary. Authorities should take into account the effect the stay-at-home order may have on PA and sedentary behavior and as a result, on health. Stay-at-home orders should be the last considered restriction, given its detrimental consequences.
