The identity of specimens belonging to the genus Euseius Wainstein, 1962 found on several trees in France is investigated. These specimens are morphologically close to Euseius stipulatus (Athias-Henriot, 1960) except for the shape of the spermatheca and the dorsal shield reticulation. The aim of the present study was to determine if these specimens belong to this latter species and if the shape of the spermatheca could be considered a reliable diagnostic character. Thirty-four characters, including idiosomal seta lengths, were measured and molecular tests (12S rDNA, COI mtDNA) were carried out. Although small, significant differences between populations of Euseius sp. were observed. The morphometric differences between E. stipulatus and Euseius sp. were very small except for the seta z2 and for the length of the ventrianal shield, as well as the length and form of the spermatheca. Molecular analyses support that Euseius sp. and E. stipulatus are two different species. Euseius sp. has been described as a new species to science in another publication under the name Euseius gallicus. Reliability of some morphological characters for species diagnosis is discussed. Nous etudions l'identite d'individus appartenant au genre Euseius Wainstein, 1962 recoltes sur quatre especes d'arbres en France. Ces specimens sont morphologiquement tres proches d'Euseius stipulatus (Athias-Henriot, 1960) excepte pour la forme de la spermatheque et la reticulation du dorsum. Le but de notre etude est de determiner si ces specimens appartiennent a cette derniere espece et par consequent, si la forme de la spermatheque peut etre utilisee comme un critere diagnostic fiable. Trente-quatre caracteres, dont la longueur des soies de l'idiosoma, ont ete mesures et des tests moleculaires (12S rDNA, COI mtDNA) ont ete realises. De faibles differences, bien que significatives, ont ete observees entre les differentes populations d'Euseius sp. Les differences morphologiques entre E. stipulatus et Euseius sp. se sont egalement revelees tres faibles, excepte pour les longueurs de la soie z2, de la plaque ventrianale et la longueur et la forme de la spermatheque. Cependant, les tests moleculaires montrent qu'Euseius sp. et E. stipulatus sont deux especes differentes. Les specimens d'Euseius sp. ont ete decrits comme une nouvelle espece pour la science dans une autre publication sous le nom d'Euseius gallicus. Une discussion sur la pertinence des caracteres morphologiques pour la diagnose des especes de Phytoseiidae est proposee.

The identity of specimens belonging to the genus Euseius found on several trees in France is investigated. Previous molecular and morphological analyses have shown that the new species herein described is different from Euseius stipulatus. Among the 187 species belonging to the genus Euseius, four of them (Euseius querci, Euseius amissibilis, Euseius kirghisicus and Euseius longiverticalis) seem to be morphologically close to this new species. However, none were very similar. This paper reports the description of this new species: Euseius gallicus sp. nov. Kreiter and Tixier. [ABSTRACT FROM AUTHOR]

Physical activity is a meaningful part of life, which starts before birth and lasts until death. There are many health benefits to be derived from physical activity, hence, regular engagement is recommended on a weekly basis. However, these recommendations are often not met. This raises the question: when and why are people motivated to be physically active? Attempts to explain the motivation for physical activity (or lack thereof) have been the research interest for many years and disciplines. In this review, we provide evidence suggesting that physical activity behavior and the psycho-physiological foundations thereof Physical activity is a meaningful part of life, which starts before birth and lasts until death. There are many health benefits to be derived from physical activity, hence, regular engagement is recommended on a weekly basis. However, these recommendations are often not met. This raises the question: when and why are people motivated to be physically active? Attempts to explain the motivation for physical activity (or lack thereof) have been the research interest for many years and disciplines. In this review, we provide evidence suggesting that physical activity behavior and the psycho-physiological foundations thereof are influenced by evolution, genetics, life stage, and the environment. The psycho-physiological foundations in turn comprise motivational and volitional factors as described in traditional psychological theories, psychological states and traits such as affective and stress reactions, as well as physiological states and systems (e.g. anatomical development and neural networks and transmitters). Importantly, physical activity elicits differential physiological responses and subjective experiences, which may impact future physical activity behavior and motivation. In summary, the interplay of psycho-physiological mechanisms and the importance of examining the ultimate mechanism for physical activity behavior are emphasized. The synthesis of knowledge provided in this review provides impetus for theory development and can facilitate the promotion of physically active lifestyles.

Regular physical activity (PA) is beneficial for cognitive health, and cathepsin B (CTSB) - a protease released by skeletal muscle during PA - acts as a potential molecular mediator of this association. PA-induced metabolic and mechanical stress appears to increase plasma/serum CTSB levels. CTSB facilitates neurogenesis and synaptic plasticity in brain regions (e.g., hippocampus and prefrontal cortex) that support performance in specific cognitive domains including memory, learning, and executive function. However, the evidence regarding the role of PA-induced changes in CTSB as a mediator of PA-induced cognitive health in humans is mixed. To guide future research, this article identifies key factors that may explain the observed heterogeneity in the findings from human studies and proposes a PA-CTSB-cognition model., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2024 Elsevier Ltd.

Acknowledging the detrimental effects of prolonged sitting, this study examined the effects of an acute exercise break during prolonged sitting on executive function, cortical hemodynamics, and microvascular status. In this randomized crossover study, 71 college students completed three conditions: (i) uninterrupted sitting (SIT); (ii) SIT with a 15 min moderate-intensity cycling break (MIC); and (iii) SIT with a 15 min vigorous-intensity cycling break (VIC). Behavioral outcomes, retinal vessel diameters (central retinal artery equivalents [CRAE], retinal vein equivalents [CRVE], arteriovenous ratio [AVR]), cortical activation, and effective connectivity were evaluated. Linear mixed models identified significant positive effects of exercise conditions on behavioral reaction time (RT), error rate, and inverse efficiency score (β = -2.62, -0.19, -3.04: ps < 0.05). MIC and VIC conditions produced pre-to-post-intervention increases in CRAE and CRVE (β = 4.46, 6.34), frontal activation, and resting-state and task-state causal density (β = 0.37, 0.06) (ps < 0.05) compared to SIT; VIC was more beneficial for executive function and neurobiological parameters. The effect of AVR on average RT was mediated through task-based causal density (indirect effect: -0.82). Acutely interrupting prolonged sitting improves executive function, microvascular status, and cortical activation and connectivity, with causal density mediating the microvascular-executive function link., (© 2024 The Author(s).

Despite substantial research efforts to increase engagement in physical activity (PA), children are not sufficiently active. Dual-process theories suggest that PA behavior regulation occurs through both controlled (i.e., reflective, conscious) and automatic (i.e., non-reflective, less conscious) processes. Automatic processes depend on affective valuations and attitudes towards PA and have been shown to predict PA behavior. However, their role in PA behavior regulation in children remains unclear. Therefore, the current study investigated the unique association of automatic attitudes towards PA on self-reported seven-day PA recall, after accounting for the effects of known controlled precursors of PA (i.e., explicit attitudes, PA self-efficacy, and PA intentions). In a cross-sectional design, 69 children (age = 10.8 ± 0.6 years) completed the Single-Category Implicit Association Task (SC-IAT) and self-reported measures of PA and controlled precursors of PA. In a hierarchical regression analysis, controlled processes accounted for 28.3 % of the variance in PA behavior. Although the bivariate association between automatic attitudes and PA was not significant, the association between them became significant but negative in the fully adjusted model (b = -1.70; p = 0.025). The fully adjusted model accounted for 35.0 % of the variance in PA. In summary, the findings indicated that both controlled and automatic processes predicted PA in children, although the association with automatic attitudes was not in the expected direction in the adjusted model. Future studies are warranted to further understand the role of automatic processes in the regulation of PA behavior in children., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Meeting 24-h movement behaviors (24-HMB: physical activity [PA], screen time [ST], and sleep [SL]) recommendations may be associated with positive health outcomes among youth with specific mental, behavioral, and neurodevelopmental (MBD) conditions. However, temporal trends and disparities in meeting 24-HMB guidelines in these higher-risk groups have not been investigated, hampering the development of evidence-based clinical and public health interventions., Methods: Serial, cross-sectional analyses of nationally National Survey of Children's Health (NSCH) data (including U.S. youth aged 6-17 years with MBD conditions) were conducted. The time-trends survey data was conducted between 2016 and 2021. The prevalence of 24-HMB adherence estimates were reported for the overall sample and for various sociodemographic subgroups. The subgroups analyzed included: age group (children[aged 6 to 13 years], adolescents[aged 14 to 17 years]), sex, socioeconomic status, and ethnicity., Results: Data on 52,634 individuals (mean age, 12.0 years [SD,3.5]; 28,829 [58.0 %] boys) were analyzed. From 2016 to 2021 the estimated trend in meeting PA + ST + SL guidelines declined (-0.8 % [95%CI, -1.0 % to -0.5 %], P for trend <0.001), whereas meeting none of 24-HMB guidelines increased (2.2 % [1.8 % to 2.6 %], P for trend <0.001). White participants, children, and boys reported higher estimated prevalence of meeting full integrated (PA + ST + SL) guidelines., Discussion: The temporal trends observed in this study highlight the importance of consistently monitoring movement behavior among MBD youth and identifying variations by sociodemographic groups in meeting 24-HMB guidelines for health promotion within these vulnerable groups., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Background: Contemporary 24-h movement behavior (24-HMB) guidelines provide recommendations on time spent on physical activity (PA), screen time (ST), and sleep (SL). There is evidence of physiological and psychological health benefits associated with meeting such guidelines. However, the prevalence of meeting 24-HMB guidelines among youth prescribed eyeglasses/contact lenses is less clear. The primary purpose of this cross-sectional analysis was to examine the prevalence of partially or fully meeting 24-HMB guidelines in U.S. youth prescribed eyeglasses/contact lenses, and variations in meeting the guidelines by demographic, health status, and environmental attributes., Methods: Data from the 2021 National Survey of Children's Health (NSCH) yielded a target subpopulation of 8523 youth aged 6-17 years (54.22 % girls) prescribed eyeglasses/contact lenses. The representative sample of US children and adolescents was used to estimate the prevalence of meeting 24-HMB guidelines, and a multinomial logistic regression analysis was conducted to examine the odds of meeting 24-HMB guidelines by demographic, health status, and environmental variables., Results: Overall, only 6.57 % met all three 24-HMB guidelines, 23.74 % did not meet any of the three 24-HMB guidelines, and 3.57 %, 10.88 %, and 29.98 % met single guidelines for physical activity, screen time, or sleep duration, respectively, while 25.27 % met any of two 24-HMB guidelines. Female participants were less likely to meet PA + SL guidelines (OR = 0.57, 95 % CI [0.38, 0.56]) but more likely to meet ST + SL guidelines (OR = 1.52, 95 % CI [1.20, 1.91]). Hispanic participants were less likely to meet PA + ST (OR = 0.28, 95 % CI [0.14, 0.52]) guidelines and all three guidelines (OR = 0.41, 95 % CI [0.23, 0.71]) while participants identified as black (OR = 0.33, 95 % CI [0.21, 0.51]) were significantly less likely to meet ST + SL guidelines. With respect to health status, overweight status, repeated/chronic physical pain, and born premature, were detrimentally associated with meeting two or more 24-HMB guidelines. Living in neighborhoods with parks or playgrounds and neighborhood safety were positively linked to meeting the guidelines while living in neighborhoods with sidewalks or walking paths was negatively linked to meeting PA + ST guidelines., Conclusion: In U.S. youth prescribed eyeglasses/contact lenses the prevalence of meeting all three 24-HMB guidelines was low, especially the low prevalence observed in female participants, Hispanic and black participants, participants with overweight status, repeated/chronic pain, born premature, living in neighborhoods with sidewalks. Policy makers should take initiative to promote integrated guidelines among this special age group for health benefits., (Copyright © 2024 Elsevier Ltd. All rights reserved.)

Background: The present study assessed physical activity (PA) and sedentary behavior (SB) levels and their motivational and emotional health-related correlates, in outpatients following a cardiovascular rehabilitation (CR) program, and compared these variables with those of a healthy control group., Methods: The study included 119 participants: 68 CR outpatients (M age 57.76 ± 10.76; 86.76% males) and 51 control participants matched on age (M age 57.35 ± 6.33 years; 45.10% males). PA and SB were assessed using accelerometers during the first week post-discharge for outpatients and during a typical week for controls. Motivational (i.e., perceived capabilities, affective and instrumental attitudes, intention, approach-avoidance tendencies) and emotional health-related variables (i.e., anxiety, depressive symptoms, fatigue, pain intensity) were measured using validated scales. PA and SB data from 17 outpatients and 42 controls were valid for analysis, resulting in a final sample of 59 participants., Results: CR outpatients engaged an average of 60.21 (± 34.79) min of moderate-to-vigorous PA (MVPA), and 548.69 (± 58.64) min of SB per day, with 18 more minutes of MVPA per day than controls (p = .038). Univariate and multivariate regressions indicated that positive affective attitudes were associated with higher MVPA (b = 10.32, R 2  = 0.07, p = .029), and that males spent more time in SB than females (b = 40.54, R 2  = 0.09, p = .045). Univariate and multivariate logistic regressions showed that meeting the World Health Organization's weekly guidelines for MVPA was associated with higher perceived capabilities toward PA and more positive affective attitudes (OR = 1.17, p = .030; OR = 1.26, p < .001, respectively). Interaction tests showed no significant differences in these results between outpatients and controls., Conclusion: The study highlights an association between higher perceived capabilities and positive affective attitudes toward PA with higher PA levels after outpatient CR. While these findings suggest that enhancing these motivational variables may be beneficial for increasing PA levels after CR, longitudinal and experimental studies are needed to further establish their role., (© 2024.

Team-based physical activity (PA) can improve social cognition; however, few studies have investigated the neurobiological mechanism underlying this benefit. Accordingly, a hyper-scanning protocol aimed to determine whether the interbrain synchrony (IBS) is influenced by an acute bout of team-based PA (i.e., tandem rope skipping). Specifically, we had socially avoidant participants (SOA, N=15 dyads) and their age-matched controls (CO, N=16 dyads) performed a computer-based cooperative task while EEG was recorded before and after two different experimental conditions (i.e., 30-min of team-based PA versus sitting). Phase locking value (PLV) was used to measure IBS. Results showed improved frontal gamma band IBS after the team-based PA compared to sitting when participants received successful feedback in the task (M skipping = 0.016, M sittting  = -0.009, p = 0.082, η p 2  = 0.387). The CO group showed a larger change in frontal and central gamma band IBS when provided failure feedback in the task (M skipping  = 0.017, M sittting  = -0.009, p = 0.075, η p 2  = 0.313). Thus, results suggest that socially avoidant individuals may benefit from team-based PA via improved interbrain synchrony. Moreover, our findings deepen our understanding of the neurobiological mechanism by which team-based PA may improve social cognition among individuals with or without social avoidance., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

While the dopaminergic system is important for cognitive processes, it is also sensitive to the influence of physical activity (PA). We summarize current evidence on whether PA-related changes in the human dopaminergic system are associated with alterations in cognitive performance, discuss recent advances, and highlight challenges and opportunities for future research., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2024 Elsevier Ltd.

Objective: There is evidence that complex relationships exist between motor functions, brain structure, and cognitive functions, particularly in the aging population. However, whether such relationships observed in older adults could extend to other age groups (e.g., younger adults) remains to be elucidated. Thus, the current study addressed this gap in the literature by investigating potential associations between motor functions, brain structure, and cognitive functions in a large cohort of young adults., Methods: In the current study, data from 910 participants (22-35 yr) were retrieved from the Human Connectome Project. Interactions between motor functions (i.e., cardiorespiratory fitness, gait speed, hand dexterity, and handgrip strength), brain structure (i.e., cortical thickness, surface area, and subcortical volumes), and cognitive functions were examined using linear mixed-effects models and mediation analyses. The performance of different machine-learning classifiers to discriminate young adults at three different levels (related to each motor function) was compared., Results: Cardiorespiratory fitness and hand dexterity were positively associated with fluid and crystallized intelligence in young adults, whereas gait speed and handgrip strength were correlated with specific measures of fluid intelligence (e.g., inhibitory control, flexibility, sustained attention, and spatial orientation; false discovery rate [FDR] corrected, p < 0.05). The relationships between cardiorespiratory fitness and domains of cognitive function were mediated by surface area and cortical volume in regions involved in the default mode, sensorimotor, and limbic networks (FDR corrected, p < 0.05). Associations between handgrip strength and fluid intelligence were mediated by surface area and volume in regions involved in the salience and limbic networks (FDR corrected, p < 0.05). Four machine-learning classifiers with feature importance ranking were built to discriminate young adults with different levels of cardiorespiratory fitness (random forest), gait speed, hand dexterity (support vector machine with the radial kernel), and handgrip strength (artificial neural network)., Conclusions: In summary, similar to observations in older adults, the current study provides empirical evidence (i) that motor functions in young adults are positively related to specific measures of cognitive functions, and (ii) that such relationships are at least partially mediated by distinct brain structures. Furthermore, our analyses suggest that machine-learning classifier has a promising potential to be used as a classification tool and decision support for identifying populations with below-average motor and cognitive functions., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Objective: In high-income countries, people with low socio-economic status (SES) engage in less leisure-time physical activity (PA) than those with higher SES. Beyond a materialistic account of this difference, the role of motivational precursors-among which attitudes are emblematic-remains poorly understood, particularly when it comes to dissociating the automatic vs. deliberative components of attitudes. This pre-registered study aimed to examine the associations between SES (i.e. income and educational attainment) and motivational precursors of PA (i.e. explicit and implicit attitudes), and whether gender and age may moderate these relationships., Method: We used data from 970 adults (64% of women; mean age = 33 ± 12 years) from the Attitudes, Identities, and Individual Differences (AIID) study., Results: Results of multiple linear regression analyses showed that participants with the highest level of income (>150,000$ per year) reported more positive explicit and implicit attitudes towards PA than those with lower income. Exploratory analysis further showed that women reported weaker explicit attitudes towards PA, while both explicit and implicit attitudes towards PA became weaker at age increases. In contrast, educational attainment was not significantly associated with those attitudes, and there was only mixed evidence for a moderating role of participants' gender on the pattern of associations., Conclusion: Our findings suggest that both the explicit and implicit attitudes towards PA may be socially patterned. Future intervention studies should examine whether these attitudinal differences could be reduced, and whether such a reduction could help buffer the unequal participation in PA behaviors across social groups.

Objectives: Previous literature has primarily viewed physical effort as an aversive experience. However, recent research suggests that effort can also be valued positively. These differences in approach and avoidance tendencies toward physical effort may play a key role in the self-regulation of physical activity behaviors. The aim of this study was to develop a scale that measures these tendencies and contributes to a better understanding of physical effort and how it affects behavior., Methods: The Physical Effort Scale (PES) was developed in Study 1 based on expert evaluations (n = 9) and cognitive interviews (n = 10). In Study 2 (n = 680, 69% female), content validity and dimensional structure were examined using principal component analysis and confirmatory factor analysis. Item reduction was conducted using item response theory. Preliminary construct validity was explored using regression. Study 3 (n = 297, 71% female) was used to validate dimensional structure, internal consistency, and construct validity, and to assess test-retest reliability., Results: In Study 1, 44 items were rated for content validity, of which 18 were selected and refined based on cognitive interviews. Analyses from Study 2 allowed reducing the scale to 8 items with a two-dimension structure: tendency to approach (n = 4) and to avoid physical effort (n = 4). The two subscales showed high internal consistency (α = 0.897 for the approach dimension and 0.913 for the avoidance dimension) and explained usual levels of physical activity, providing preliminary evidence of construct validity. Study 3 confirmed the two-dimension structure with high internal consistency (α = 0.907 and 0.916 for the approach and avoidance dimension, respectively) and revealed acceptable test-retest reliability (intraclass correlation >0.66). Patterns of associations with other constructs showed expected relationships, confirming the concurrent, convergent, and discriminant validity of the scale., Conclusions: The PES is a valid and reliable measure of individual differences in the valuation of physical effort. This scale can assess the propensity to engage in physically demanding tasks in non-clinical populations. The PES and its manual are available in the Supplementary Material., Competing Interests: Declaration of competing interest None to declare., (Copyright © 2024 Elsevier Ltd. All rights reserved.)

Higher levels of physical activity are known to benefit aspects of brain health across the lifespan. However, the role of sedentary behavior (SB) is less well understood. In this review we summarize and discuss evidence on the role of SB on brain health (including cognitive performance, structural or functional brain measures, and dementia risk) for different age groups, critically compare assessment approaches to capture SB, and offer insights into emerging opportunities to assess SB via digital technologies. Across the lifespan, specific characteristics of SB (particularly whether they are cognitively active or cognitively passive) potentially act as moderators influencing the associations between SB and specific brain health outcomes. We outline challenges and opportunities for future research aiming to provide more robust empirical evidence on these observations., Competing Interests: Declaration of interests No interests are declared., (Copyright © 2024 Elsevier Ltd.

Background: This study aimed to investigate associations of meeting 24-h movement behavior (24-HMB: physical activity [PA], screen time [ST] in the school-aged youth, and sleep) guidelines with indicators of academic engagement, psychological functioning, and cognitive function in a national representative sample of U.S. youth., Methods: In this cross-sectional study, 1794 participants aged 6 to 17 years old were included for multivariable logistic regression to determine the above-mentioned associations, while adjusting for sociodemographic and health covariates., Results: The proportion of participants who met 24-HMB guideline(s) varied greatly (PA+ ST+ sleep = 34 [weighted 1.17 %], PA + ST = 23 [weighted 1.72 %], PA + sleep = 52 [weighted 2.15 %], PA = 34 [weighted 2.88 %], ST = 142 [weighted 7.5 %], ST+ sleep = 209 [weighted 11.86 %], sleep = 725 [weighted 35.5 %], none = 575 [weighted 37.22 %]). Participants who met ST guideline alone and integrated (ST + Sleep and ST + sleep + PA) guidelines demonstrated the consistently beneficial associations with learning interest/curiosity, caring for school performance, completing required homework, resilience, cognitive difficulties, self-regulation (ps < 0.05)., Conclusion: Meeting 24-HMB guidelines in an isolated or integrative manner was associated with improved academic engagement, psychological functioning, and reduced cognitive difficulties. These findings highlight the importance of the promotion of 24-HMB guidelines in youth with internalizing problems. Future longitudinal studies are needed to investigate whether changes or modifications of meeting specific 24-HMB guidelines (especially ST) is beneficial for youth with internalizing problems., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024 Elsevier B.V.

Objective: Despite their potential in improving health behaviors, such as physical activity (PA), the effectiveness of interventions targeting automatic precursors remains contrasted. We examined the effects of a single session of ABC training - a personalized consequence-based approach-avoidance training - on PA, relative to an active control condition and a control condition., Methods: Middle-aged US participants (N = 360, 53 % of women) either completed an ABC training (being instructed to approach PA to obtain self-relevant consequences), an approach-avoidance training (approaching PA in 90 % of trials), or a control training (approaching PA in 50 % of trials). Participants selected antecedents (e.g., "When I have little time") in which personalized choices between PA and sedentary alternatives were likely to occur. In the ABC training only, after approaching PA, self-relevant consequences were displayed (e.g., increase in the health status of participant's avatar). Primary outcome was self-reported PA seven days after the intervention. Secondary outcomes included choices for PA (vs sedentary) alternatives in a hypothetical free-choice task, intention, automatic and explicit attitudes toward PA., Results: No significant effect of the ABC intervention on PA was observed, so as on intention and explicit attitudes. However, the ABC intervention was associated with higher odds of choosing PA alternatives in the free-choice task and with more positive automatic attitudes toward PA., Conclusions: While the ABC training was not effective at improving PA, its effects on choices and automatic attitudes suggest that this intervention may still have potential. Future studies with intensive trainings and device-based measures of PA remains needed., Competing Interests: Declaration of competing interest None., (Copyright © 2023 The Authors.

Background: Emerging evidence points towards the psychological benefits of meeting 24-hour movement behavior (24-HMB) guidelines, but such associations have not yet been investigated among children and adolescents of prescribed eyeglasses/contact lenses. To this end, we examined associations of meeting 24-HMB guidelines with internalizing and externalizing challenges in this population., Methods: We used data from the 2021 National Survey of Children's Health, a cross-sectional survey including a representative sample of US children and adolescents. Data on movement behaviors (physical activity [PA], sedentary behavior operationalized via screen time [ST], and sleep duration [SL]) and internalizing and externalizing problems were collected through caregiver proxy reports. Caregivers completed questionnaires for 6030 (2799 girls) US children and adolescents of prescribed eyeglasses/contact lenses. Logistic regression analyses were conducted to determine the above-presented associations., Results: Only 7.1 % of those prescribed eyeglasses/contact lenses met all three 24-HMB guidelines, while they were more likely to meet SL guideline alone (32.1 %) in relation to other independent guidelines including PA (2.5 %) and ST (10.9 %). Compared to not meeting any of the three 24-HMB guidelines, meeting at least two guidelines (25.22 %) was significantly linked to lower odds of internalizing problems and externalizing problems., Conclusion: Meeting at least two components of the 24-HMB guidelines was beneficially linked to internalizing and externalizing problems. Thus, strategies or intervention programs that focus on meeting 24-HMB guidelines should be implemented among children and adolescents of those prescribed eyeglasses/contact lenses to foster coping with psychological issues., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 The Author(s).)

During their activities of daily living, humans run, walk, stand, sit and lie down. Recent changes in our environment have favored sedentary behavior over more physically active behavior to such a degree that our health is in danger. Here, we sought to address the problem of excessive time spent seated from various theoretical viewpoints, including postural control, human factors engineering, human history and health psychology. If nothing is done now, the high prevalence of sitting will continue to increase. We make a case for the standing position by demonstrating that spending more time upright can mitigate the physiological and psychological problems associated with excessive sitting without lowering task performance and productivity. The psychological literature even highlights potential benefits of performing certain tasks in the standing position. We propose a number of recommendations on spending more time (but not too much) in the standing position and on more active, nonambulatory behaviors. There is a need to inform people about (i) harmful consequences of excessive sitting and (ii) benefits of spending more time performing active, nonambulatory behaviors. One clear benefit is to reduce detrimental health consequences of excessive sitting and to provide potential additional benefits in terms of productivity and performance.
