Comparison between Motor Performance of People with Multiple Sclerosis during a Virtual Reality Task Practiced on Concrete and Abstract Devices: A Cross-Sectional Randomized Study.

Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system with unknown etiology, resulting in various impairments that necessitate continuous rehabilitation to enhance functionality, quality of life, and motor function, including through Virtual Reality (VR) therapy. Comparing tasks in virtual environments and their potential skill transfer to real-world settings could aid in optimizing treatment programs to improve motor performance in individuals with MS. This study aimed to determine whether practicing acquisition and retention phases using two distinct interfaces (concrete-Touch Screen or abstract-Kinect system) affects performance in a subsequent task using a different interface (transfer phase). A randomized clinical trial was conducted with 56 volunteers with MS and 41 controls. Participants engaged in a computer game where they burst as many bubbles as possible within 10 s per attempt. After the acquisition and retention phases, all participants switched interfaces (e.g., those using Kinect switched to Touchscreen and vice versa). Significant performance improvements were observed in both groups during the acquisition phase, which were maintained in the retention phase. Although the abstract interface was more challenging for both groups, only the MS group that practiced with the abstract interface successfully transferred their improvements to the concrete interface. Thus, despite the increased difficulty of the abstract task during practice, it led to better performance transfer when required to complete a subsequent concrete task, suggesting that abstract devices may be beneficial in clinical practice for improving motor function in people with MS.

Associations Between Substitution of Sedentary Behavior Patterns With Physical Activity and Cardiovascular Risk Factors in Adolescents: A 3-Year Longitudinal Study.

BACKGROUND: Little is known on how the substitution of time spent in sedentary behavior (SB) patterns with time spent in physical activity impacts cardiovascular risk factors during adolescence. The study aimed to investigate how the substitution of time spent in SB and sedentary bouts with time spent in different physical activity intensities was associated with longitudinal changes in cardiovascular risk factors in analyses stratified by sex. METHODS: This is a prospective cohort study with a mean follow-up period of 3.2 (±0.34) years, involving 109 (60 girls and 49 boys) Brazilian adolescents. Body mass index, waist circumference, and cardiorespiratory fitness were the cardiovascular risk factors considered. A cardiovascular risk score was calculated. Sedentary bouts, light physical activity (LPA), and moderate to vigorous physical activity (MVPA) were measured by accelerometers. Multivariate linear regression models adopting the isotemporal substitution were used to analyze the association between substitution of 10 minutes per day of sedentary bouts with LPA and MVPA and risk factors. All analyses considered 5% significance levels. RESULTS: Substitutions of SB, short and long bouts, with MVPA were associated with higher cardiorespiratory fitness in boys (ß = 0.077; 95% confidence interval, 0.001 to 0.55; ß = 0.076; 95% confidence interval, 0.003 to 0.154; and ß = 0.084; 95% confidence interval, 0.001 to 0.167, respectively). No associations were observed when analyses involved substitution of sedentary bouts with LPA, adiposity, cardiovascular risk score, and girls. CONCLUSIONS: Substituting SB bouts with MVPA appears to favorably influence changes of cardiorespiratory fitness in boys during adolescence. Greater benefits appear to occur when longer sedentary bouts are substituted by MVPA.

The use of digital platforms and physical activity practice in a population from southern Brazil: Findings from the PAMPA Cohort.

Objective: We aimed to identify the factors associated with using digital platforms for physical activity during the COVID-19 pandemic among adults living in Southern Brazil. We also compared the trajectory of physical activity between users and non-users and by type of digital platform used. Methods: We analyzed data from the PAMPA (Prospective Study About Mental and Physical Health in Adults) cohort. The study started in June 2020, and tracked participants through three waves (December 2020, June 2021, and June 2022). The exposure variable was usingf digital platforms for physical activity. The outcome measure was minutes per week of physical activity. We employed a generalized linear model with robust variance to explore the interaction between time and the use of digital platforms, adjusting for sociodemographic covariates and the presence of chronic diseases. Results: The proportion of participants using digital platforms for physical activity declined from 36.8% in 2020 to 25.6% in 2021 and further to 13.5% in 2022. Using digital platforms for physical activity was associated with a higher mean daily physical activity during the COVID-19 pandemic. Participants who used digital platforms were more likely to be physically active when compared to their inactive contemparts throughout the entire study period. Notably, social media emerged with greater influence in the physical activity practice among digital platforms. Conclusion: Using these platforms had a positive impact on increasing the level of physical activity among the participants.

Physical activity levels in patients with chronic venous insufficiency.

BACKGROUND: Increasing the levels of physical activity (PA) is widely recommended for people with chronic venous insufficiency (CVI). However, studies investigating the patterns of PA and adherence to PA guidelines using objective measures are lacking. OBJECTIVE: The primary aim was to examine the patterns of PA and adherence to PA guidelines among patients with CVI. A secondary aim was to identify whether adherence to PA recommendations differed according to patients' sociodemographic and clinical characteristics. METHODS: This cross-sectional study included 96 patients with CVI with Clinical-Etiology-Anatomy-Pathology (CEAP) C3 to C6 (69.1% women 59 ± 11 years; 51.5% C5-C6 on CEAP classification). Objective time spent in PA was measured by a triaxial accelerometer. To examine adherence to PA guidelines, patients were grouped as meeting (or) the recommendations if they had at least 150 min/week of moderate to vigorous PA. Sociodemographic and clinic characteristics were obtained by self-report. Binary logistic regression was employed to examine whether sociodemographic and clinical characteristics were associated with adherence to PA guidelines. T-tests were employed to compare PA levels at different intensities according to patients' age. RESULTS: Patients spent an average of 311.4 ± 91.5 min/week, 42.1 ± 28.0 min/week, and 19.8 ± 17.8 min/week in low-light PA, high-light PA, and moderate-to-vigorous PA, respectively. The proportion of patients meeting PA recommendations was 36.2%, and older patients had lower odds (OR = 0.94; 95%CI: 0.89 to 0.99). Additional analysis reinforced that by showing lower time in high-light PA (51.2 ± 30.0 min/day vs. 31.9 ± 21.8 min/day; p = .001) and moderate-to-vigorous PA (24.3 ± 15.8 min/day vs. 14.8 ± 18.8 min/day; p = .012) among older patients than their peers younger. CONCLUSION: Our findings showed that 36,2% of CVI patients met PA recommendations, with lower odds found among older patients. Public health interventions to enhance PA engagement among CVI patients should prioritize those who are older.

Global Physical Activity, Active Commuting to School, and Sedentary Behavior Among Latin American Adolescents: Global School-Based Student Health Survey and the National School Health Survey.

BACKGROUND: This study aimed to compare the overall prevalence, stratified by sex and age group of global physical activity (GPA), active commuting to school (ACS), and sedentary behavior (SB) among adolescents from ten Latin American countries, and to assess the correlation of Development Index with the indicators. METHODS: This research is grounded on data from the Global School-Based Student Health Survey (2009-2015) and the 2015 Brazilian National School Health Survey. The prevalence and 95% confidence intervals for GPA (≥5 d/wk), ACS (≥1 d/wk), and SB (>2 h/d) were calculated using the chi-square test to compare the sexes (male; female) and age group (≤13 y; 14 y; 15 y; ≥16 y). We also performed Pearson correlation analysis with the Human Development Index. RESULTS: The prevalence of indicators ranged from 16.1% to 28.2% for GPA, from 56.7% to 71.2% for ACS, and from 20.7% to 62.6% for SB. Boys generally had a higher prevalence of GPA and ACS, and girls had a higher prevalence of SB. The prevalence of the indicators by age group varied between countries, with significant differences observed in some, depending on each indicator. A positive correlation was observed between Human Development Index, GPA, and SB. CONCLUSION: Health promotion policies must include guidelines that encourage and promote a more active and less sedentary lifestyle among young people in Latin America, considering specific groups, the local socioeconomic context, and differences between countries.

Effects of Therapies Involving Plyometric-Jump Training on Physical Fitness of Youth with Cerebral Palsy: A Systematic Review with Meta-Analysis.

The aim of this systematic review was to assess the effects of plyometric-jump training (PJT) on the physical fitness of youth with cerebral palsy (CP) compared with controls (i.e., standard therapy). The PRISMA 2020 guidelines were followed. Eligibility was assessed using the PICOS approach. Literature searches were conducted using the PubMed, Web of Science, and SCOPUS databases. Methodological study quality was assessed using the PEDro scale. Data were meta-analyzed by applying a random-effects model to calculate Hedges' g effect sizes (ES), along with 95% confidence intervals (95% CI). The impact of heterogeneity was assessed (I2 statistic), and the certainty of evidence was determined using the GRADE approach. Eight randomized-controlled studies with low-to-moderate methodological quality were included, involving male (n = 225) and female (n = 138) youth aged 9.5 to 14.6 years. PJT interventions lasted between 8 and 12 weeks with 2-4 weekly sessions. Compared with controls, PJT improved the muscle strength (ES = 0.66 [moderate], 95% CI = 0.36-0.96, p < 0.001, I2 = 5.4%), static (ES = 0.69 [moderate], 95% CI= 0.33-1.04, p < 0.001, I2 = 0.0%) and dynamic balance (ES = 0.85 [moderate], 95% CI = 0.12-1.58, p = 0.023, I2 = 81.6%) of youth with CP. Therefore, PJT improves muscle strength and static and dynamic balance in youth with CP compared with controls. However, more high-quality randomized-controlled trials with larger sample sizes are needed to provide a more definitive recommendation regarding the use and safety of PJT to improve measures of physical fitness.

Atividade física e comportamento sedentário de adolescentes da rede pública: uma análise de redes / Physical activity and sedentary behavior of adolescents in public schools: a network analysis

O Programa Saúde na Escola (PSE) e a Pesquisa Nacional de Saúde do Escolar (PeNSE) merecem destaque entre as ações de promoção e monitoramento da saúde de estudantes brasileiros. Nesse contexto, a promoção da atividade física em escolas integra as ações do PSE, além de ser monitorada pela PeNSE. O presente estudo verificou a associação entre características do indivíduo, socioeconômicas, de ações de promoção da atividade física e da saúde na escola, incluindo a adesão escolar ao PSE, com os comportamentos ativo e sedentário de estudantes brasileiros matriculados em escolas públicas, participantes da PeNSE ­ 2019. Trata-se de estudo com dados secundários. A amostra contou com 48.204 adolescentes, com idades entre 13 e 18 anos. As variáveis foram coletadas através de questionário. A adesão da escola ao PSE é uma das variáveis de maior centralidade da rede, com destaque para a sua medida de força (1,433); entretanto, apresentou-se pouco conectada aos indicadores de atividade física e ao comportamento sedentário dos jovens. A análise de redes mostrou que o gênero feminino participa menos das atividades físicas em aulas de Educação Física (-0,176) e em tempo livre (-0,283), assim como ter internet em casa foi a principal variável associada com o maior tempo de exposição aos comportamentos sedentários (0,225). Os resultados apontam para a importância da adesão escolar ao PSE e para a necessidade do desenvolvimento de ações efetivas de promoção da atividade física como estratégia de promoção da saúde no âmbito do PSE.

The School Health Program (SHP) and the National School Health Survey (PeNSE) deserve to be high-lighted among actions to promote and monitor the health of Brazilian students. In this context, the promo-tion of physical activity in schools represents part of the SHP actions, in addition to being monitored by the PeNSE. The present study verified the association between individual and socioeconomic characteristics, and actions to promote physical activity and health in school, including school adherence to the SHP, with the active and sedentary behaviors of Brazilian students enrolled in public schools, participants of the PeNSE ­ 2019. This is a study with secondary data, of 48,204 adolescents, aged between 13 and 18 years. The variables were collected using a questionnaire. The school 's adherence to the SHP is one of the variables with the highest centrality in the network, with emphasis on its measure of strength (1.433); however, it was poorly connected to indicators of physical activity and sedentary behavior in young people. Network analysis showed that females participate less in physical activities in Physical Education classes (-0.176) and in free time (-0.283). In addition, having internet at home was the main variable associated with longer exposure time to sedentary behaviors (0.225). The results point to the importance of school adherence to the SHP and the need to develop effective actions to promote physical activity as a health promotion strategy within the scope of the SHP.

Associação entre prática de atividade física e aptidão cardiorrespiratória em adolescentes / Association between physical activity practice and physical fitness in school adolescents

O objetivo do estudo foi verificar a associação entre diferentes volumes de atividade física moderada e/ou vigorosa durante o lazer e a aptidão cardiorrespiratória (ACR) adequada em adolescentes de ambos os sexos. A atividade física moderada (AFM), vigorosa (AFV ) ou moderada-vigorosa (AFMV) de lazer foi avaliada por meio de questionário e a ACR foi medida com o teste de vai-e-vem de 20m. Foram utilizados modelos de Regressão Poisson para análises. As AFM, AFV ou AFMV no lazer foram categorizadas de acordo com três limiares de atividade física no lazer (150, 300 e 420 min/sem). Foram consideras para as análises de associação as AFM, AFV e AFMV, de acordo com o compêndio de atividade físicas para adolescentes. A prática de AFMV no lazer por pelo menos 420 min/sem obteve a maior probabilidade de ACR adequada (RP = 2,03; IC95%: 1,18 ­ 3,51). Na mesma direção, a prática de AFV por pelo menos 150 min/sem também foi estatisticamente significativa (RP = 1,72; IC95%: 1,07 ­ 2,80). Os resultados indicaram uma associação positiva entre prática de atividade física no lazer e ACR, independentemente da intensidade e limiar de tempo, enfatizando que a participação em ambas as intensidades de atividade física no lazer estão associadas aos níveis adequados de aptidão cardiorrespiratória.

The aim of this study was to verify the association between different volumes of moderate and/or vigor-ous physical activity during leisure time and adequate cardiorespiratory fitness in adolescents of both sexes. Leisure-time moderate and/or vigorous physical activity (MPA, VPA, and MVPA) was assessed by means of a questionnaire and cardiorespiratory fitness was measured with the 20m back-and-forth test. Poisson regression models were used for analyses where moderate and/or vigorous physical activity in leisure time, it was categorized according to three thresholds of leisure-time physical activity (150, 300 and 420 min/week). The following factors were considered for the association analyses: MPA, VFA, and MVPA, according to the compendium of physical activity for adolescents. Leisure time MVPA for at least 420 min/week had the highest probability of adequate cardiorespiratory fitness (PR = 2.03; 95%CI: 1.18 ­ 3.51). In the same direction, the practice of VFA for at least 150 min/week was also statistically significant (PR = 1.72; 95%CI: 1.07 ­ 2.80). The results indicated a positive association between leisure time physical activity and cardiorespiratory fitness, regardless of intensity and time threshold, emphasizing that participation in both modalities of leisure time physical activity can provide substantial benefits for cardiorespiratory fitness.

Gender Differences in Physical Activity and Health-Related Authorships Between 1950 and 2019.

BACKGROUND: The objective of this study was to investigate gender differences in authorship in physical activity and health research. METHODS: A bibliometric study including 23,399 articles from 105 countries was conducted to estimate the participation of female researchers in physical activity publications from 1950 to 2019. The frequency of female researchers was analyzed and classified by first and last authors and the overall percentage of female authors by region and country. RESULTS: The proportion of female first authors increased from <10% in the 50s and 80s to 55% in the last decade. On the other hand, the proportion of last authors increased from 8.7% to 41.1% in the same period. Most publications with female researchers were from the United States, Canada, Australia, Brazil, the Netherlands, Spain, England, Germany, Sweden, and China. Nine of these countries had over 50% of the articles published by female first authors. However, in all 10 countries, <50% of the articles were published by female last authors. CONCLUSIONS: The proportion of female researchers increased over time. However, regional differences exist and should be addressed in gender equity policies. There is a gap in the participation of female researchers as last authors. By actively addressing the gender gap in research, the global society can harness the full potential of all talented individuals, regardless of gender, leading to more inclusive and impactful scientific advancements.

Comparing Video Analysis to Computerized Detection of Limb Position for the Diagnosis of Movement Control during Back Squat Exercise with Overload.

Incorrect limb position while lifting heavy weights might compromise athlete success during weightlifting performance, similar to the way that it increases the risk of muscle injuries during resistance exercises, regardless of the individual's level of experience. However, practitioners might not have the necessary background knowledge for self-supervision of limb position and adjustment of the lifting position when improper movement occurs. Therefore, the computerized analysis of movement patterns might assist people in detecting changes in limb position during exercises with different loads or enhance the analysis of an observer with expertise in weightlifting exercises. In this study, hidden Markov models (HMMs) were employed to automate the detection of joint position and barbell trajectory during back squat exercises. Ten volunteers performed three lift movements each with a 0, 50, and 75% load based on body weight. A smartphone was used to record the movements in the sagittal plane, providing information for the analysis of variance and identifying significant position changes by video analysis (p < 0.05). Data from individuals performing the same movements with no added weight load were used to train the HMMs to identify changes in the pattern. A comparison of HMMs and human experts revealed between 40% and 90% agreement, indicating the reliability of HMMs for identifying changes in the control of movements with added weight load. In addition, the results highlighted that HMMs can detect changes imperceptible to the human visual analysis.

A partial habituation method to test for anterograde and retrograde amnestic treatment effects: Evidence that antagonism of the NMDA receptor can induce anterograde but not retrograde amnestic effects.

BACKGROUND: A progressive decrease in spontaneous locomotion with repeated exposure to a novel environment has been assessed using both within and between-session measures. While both are well-established and reliable measurements, neither are useful alone as methods to concurrently assess treatment effects on acquisition and retention of habituation. NEW METHOD: We report a behavioral method that measures habituation by combining the within and between measurements of locomotion. We used a 30 min session divided into 6 five min blocks. In the first novel environment session activity was maximal in the first 5 min block but was reduced to a low level by the sixth block, indicative of within-session habituation. Using 8 daily sessions, we showed that this terminal block low level of activity progressed incrementally to the first block to achieve complete habituation. RESULTS/COMPARISON WITH EXISTING METHODS: Within-session activity across sessions was used to identify different stages of between session habituation. It was then possible to assess drug treatment effects from partial to complete habituation, so that treatment effects on retention of the previously acquired partial habituation, expressed as a reversion to an earlier within session habituation pattern (retrograde amnesia assessment), as well as the effects on new learning by the failure in subsequent sessions to acquire complete between-session habituation (anterograde amnesia assessment). CONCLUSIONS: The use of spontaneous motor activity to assess learning and memory effects provides the opportunity to assess direct treatment effects on behavior and motor activity in contrast to many learning and memory models.

Grade-4/5 motor activity log-Brazil for post-stroke individuals with a severely impaired upper limb: a validity, reliability and measurement error study.

PURPOSE: This study examined the clinimetrics of the Brazilian-Portuguese translation of the Grade-4/5 Motor Activity Log (MAL 4/5), which assesses everyday use of the more affected upper-limb (UL) in stroke survivors with moderate/severe or severe motor impairment. MATERIALS AND METHODS: The translated MAL 4/5 was administered to 47 stroke survivors with moderate/severe or severe UL motor impairment. Accelerometers were worn on participants' wrists for five days on average prior to the first assessment. Test-retest and inter-rater reliabilities were assessed using the intraclass correlation coefficient (ICC), internal consistency using Cronbach's α, and construct validity was tested with correlations with the accelerometry. The measurement error (SEM) and the minimal detectable change (MDC) were calculated. RESULTS: MAL4/5-Brazil's test-retest reliability (AOU: ICC = 0.84; QOU: ICC = 0.90), inter-rater reliability (AOU: ICC = 0.83; QOU: ICC = 0.91), internal consistency (Cronbach's α = 0.91 and 0.95 for AOU and QOU scales, respectively), the SEM and MDC were 0.3 and 0.8 points for the AOU subscale and 0.2 and 0.5 points for the QOU subscale, respectively. The construct validity (AOU scale: r = 0.67; QOU scale: r = 0.76) was high. CONCLUSION: Grade-4/5 Motor Activity Log-Brazil is a reliable and valid instrument for assessing the more-affected UL use of stroke patients with moderate/severe or severe UL motor impairments.

Reliability and concurrent validity of the Grade-4/5 MAL-Brazil were established in adults with hemiparesis moderate/severe or severe upper extremity post Stroke.The minimum detectable change for the Grade-4/5 MAL-Brazil was 0.8 points for the Amount of Use scale and 0.5 points for the Quality of Use scale.Data from the accelerometry supports the construct validity of this instrument.The assessment can now be used clinically and for research in adults with impairment upper extremity moderate/severe or severe post Stroke.

Leisure-Time Physical Activity in a Southern Brazilian City (2004-2021): Applying an Equity Lens to Time-Trend Analyses.

BACKGROUND: This study aimed to verify leisure-time physical activity trends over 15 years and monitor inequalities according to gender, self-reported skin color, and socioeconomic position in a Southern Brazilian city. A secondary aim is to evaluate intersectionalities in physical activity. METHODS: Trend analysis using 3 population-based surveys carried out in 2004, 2010, and 2021. Main outcome assessed was the prevalence of physical activity according to recommendations (150 min/wk). Inequalities dimensions measured were sex, self-reported skin color, and wealth. Intersectionalities were evaluated using Jeopardy index combining all inequality dimensions. Trend analysis was performed using least-squares weighted regression. RESULTS: We included data from 3090, 2656, and 5696 adults in 2004, 2010, and 2021, respectively. Prevalence of physical activity remains stable around 25% in the 3 years. In the 3 periods evaluated, men presented a prevalence in average 10 percentage points higher than women (SII2004 = -11.1 [95% confidence interval, CI, -14.4 to -7.8], SII2021 = -10.7 [95% CI, -13.7 to -7.7]). Skin color inequalities did not present a clear pattern. Richest individuals, in general presented a prevalence of leisure-time physical activity level 20pp higher than poorest ones (SII2004 = 20.5 [95% CI, 13.7 to 27.4]; SII2021 = 16.7 [95% CI, 11.3 to 22.0]). Inequalities were widely marked, comparing the most privileged group (represented by men, the wealthiest, and White) and the most socially vulnerable group (represented by women, the poorest, and Black/Brown). The Slope Index of Inequality for intersectionalities was -24.5 (95% CI, -31.1 to -17.9) in 2004 and -18.8 in 2021 (95% CI, -24.2 to -13.4). CONCLUSIONS: Our analysis shows that women, Black/Brown, and poor present lower leisure-time physical activity level. This group is often neglected regarding other health and social outcomes.

Habitual physical activity and sedentary behavior as predictors of dynapenia in older adults: a cross-sectional study

ABSTRACT BACKGROUND: Dynapenia is a risk factor of mortality. Therefore, the development of low-cost and easy-to-apply tools is essential to optimize the health surveillance actions of older people. OBJECTIVES: To compare the time spent on habitual physical activity (HPA) and sedentary behavior (SB) among dynapenic and non-dynapenic older adults and ascertain the predictive ability of these behaviors on outcome. DESIGN AND SETTING: A cross-sectional population epidemiological survey was conducted involving 208 older adults. METHODS: HPA and SB were quantified using the International Physical Activity Questionnaire, and dynapenia was identified by handgrip strength (women: 18.37 kgf; men: 26.75 kgf). RESULTS: The prevalence was 24.50%. In both sexes, dynapenic individuals reported a HPA median time of 70.00 minutes/week (min/wk), while non-dynapenic women and men reported HPA median times of 240.00 and 280.00 min/wk, respectively (P < 0.05). For SB among dynapenic individuals, a median of 388.75 min/day was observed in women and 428.57 min/d in men. In contrast, non-dynapenic women and men had 291.42 and 274.28 min/day in SB (P < 0.05), respectively. The best cutoff HPA to discriminate the outcome was 150.00 min/wk in women (sensitivity: 73.30%; specificity: 60.67%) and 140.00 min/wk in men (sensitivity, 71.43%; specificity, 61.54%). The best cutoff SB was 381.43 min/day in women (sensitivity, 53.30%; specificity, 84.80%) and 351.43 min/day in men (sensitivity, 71.43%; specificity, 73.85%). CONCLUSION: Older individuals with dynapenia spent less time on HPA and more time in SB. Furthermore, HPA was found to be a better discriminator of dynapenic individuals, and SB better discriminated non-dynapenic individuals.

Histerectomía abdominal y deterioro de la función física en mujeres adultas mayores colombianas / Abdominal hysterectomy and impaired physical function in colombian older women

Resumen OBJETIVO: Estimar, en mujeres adultas mayores colombianas, la asociación entre histerectomía abdominal con el deterioro de la función física y con la limitación para las actividades de la vida diaria. MATERIALES Y MÉTODOS: Estudio transversal llevado a cabo en mujeres colombianas entre 60 y 75 años que firmaron el consentimiento informado, permitieron mediciones antropométricas y contestaron un formulario con preguntas acerca de datos sociodemográficos y clínicos. Se aplicó la subescala de función física del Cuestionario SF-36. Se realizaron regresiones logísticas bivariadas: limitación para las actividades habituales o deterioro en la función física (variables dependientes) con el antecedente de histerectomía con o sin ooforectomía en la pre o posmenopausia (variables independientes). Además, se aplicaron cuatro modelos de regresión logística ajustada. RESULTADOS: Se evaluaron 700 mujeres con promedio de edad de 67.0 ± 4.8 años y 18.9 ± 6.3 años trascurridos a partir de la menopausia. A todas se les practicó histerectomía con ooforectomía durante los años de premenopausia (4.2%); histerectomía sin ooforectomía en la premenopausia (18.1%); histerectomía con ooforectomía en la posmenopausia (2.1%) e histerectomía sin ooforectomía en la posmenopausia (8.4). La histerectomía con ooforectomía, o sin esta última en la premenopausia, se relacionó con deterioro de la función física (RM: 2.67; IC95%:1.19-5.97) y 2.02 (IC95%:1.34-3.09). Igual sucedió con las actividades habituales (p < 0.05). La histerectomía con preservación o extirpación ovárica durante la posmenopausia no se asoció con deterioro de la función física (p > 0.05). CONCLUSIÓN: En la muestra estudiada se encontró relación entre la histerectomía con limitación para actividades diarias y con deterioro de la función física. La histerectomía con o sin ooforectomía practicada durante los años de premenopausia, a diferencia de la adelantada en posmenopausia, se asoció, significativamente, con deterioro del funcionamiento físico.

Abstract OBJECTIVE: To estimate the association of abdominal hysterectomy with impaired physical function and limitation of activities of daily living in elderly Colombian women. MATERIALS AND METHODS: Cross-sectional study in Colombian women aged 60-75 years who signed informed consent, allowed anthropometric measurements, and completed a form with questions on socio-demographic and clinical data. The physical function subscale of the SF-36 questionnaire was used. Bivariate logistic regressions were performed: limitation of usual activities or impairment of physical function (dependent variables) with history of hysterectomy with or without oophorectomy in pre- or postmenopause (independent variables). Four adjusted logistic regression models were also used. RESULTS: Seven hundred women with a mean age of 67.0 ± 4.8 years and 18.9 ± 6.3 years since menopause were evaluated. All had undergone hysterectomy with oophorectomy in the premenopausal years (4.2%); hysterectomy without oophorectomy in the premenopausal years (18.1%); hysterectomy with oophorectomy in the postmenopausal years (2.1%); and hysterectomy without oophorectomy in the postmenopausal years (8.4%). Hysterectomy with or without oophorectomy in premenopause was associated with impaired physical function (MR: 2.67; 95%CI: 1.19-5.97) and 2.02 (95%CI: 1.34-3.09), respectively. The same was true for usual activities (p < 0.05). Postmenopausal hysterectomy with ovarian preservation or removal was not associated with impaired physical function (p > 0.05). CONCLUSION: In the sample studied, an association was found between hysterectomy with limitation of daily activities and impaired physical function. Hysterectomy with or without oophorectomy in the premenopausal years, as opposed to early postmenopausal hysterectomy, was significantly associated with physical function impairment.

Coordenação motora global e a prática esportiva em crianças e adolescentes participantes de multiesporte / Global motor coordination and sports practice in children and adolescents multi-sport participants

RESUMO A relação entre a participação esportiva (PE) e a coordenação motora global (CMG) se associa à idade. No entanto, o tempo envolvido na PE pode ser outro mediador. Assim, o objetivo foi investigar a relação entre a CMG e a PE em crianças e adolescentes envolvidos na PE, controlado pelo tempo de prática. Para isso, foram analisados 111 meninos (88 de 6 a 9 anos; 23 de 10 a 12 anos), com PE de duas a quatro modalidades e com o tempo de prática entre um e seis anos. A CMG foi auferida pelo Körperkoordinationstest Für Kinder e a PE mediante entrevista semiestruturada com os responsáveis legais. Os coeficientes de Spearman indicaram que para as crianças dos 6 aos 9 anos de idade não houve correlação entre a CMG e a PE (p >0,05), mesmo quando controlada pelo tempo nas PE. Já para o grupo dos 10 aos 12 anos, houve correlação moderada (ρ = 0,515, p <0,01). Essa informação permite ao profissional de Educação Física entender que a experiência motora das crianças mais jovens é fundamental para potencializar o desenvolvimento motor e que sua implicação na manutenção da participação em atividades esportivas ocorrerá somente nas fases avançadas da infância.

ABSTRACT The relationship between sports participation (SP) and global motor coordination (GMC) is associated with age. However, the time of involved in SP may be another mediator. Thus, the objective was to investigate the relationship between GMC and SP in children and adolescents involved, controlled by the time of practice. For this, 111 boys were analyzed (88 aged 6 to 9 years old; 23 aged 10 to 12 years old), with SP of two to four sports and with practice time between one and six years. The GMC was assessed by the Körperkoordinationstest Für Kinder and the SP through a semi-structured interview with the legal guardians. Spearman coefficients indicated that for children aged 6 to 9 years there was no correlation between GMC and SP (p >0.05), even when controlling for time in SP. For the group aged 10 to 12 years old, there was a moderate correlation (ρ = 0.515, p <0.01). This information allows the Physical Education professional to understand that the motor experience of younger children is fundamental to enhancing motor development and that its implication in maintaining participation in sporting activities will only occur in the advanced stages of childhood.

Características e estratégias de aconselhamento para atividade física utilizadas por profissionais da atenção primária à saúde / Characteristics and counseling strategies for physical activity used by primary health care professionals

Resumo O estudo buscou descrever as características e estratégias de aconselhamento para atividade física utilizadas por profissionais da atenção primária à saúde (APS). Foi realizada uma pesquisa com 587 profissionais de saúde (85,4% mulheres) que atuam na APS de Florianópolis, no estado de Santa Catarina, Sul do Brasil. Foram considerados os aconselhamentos efetuados nos últimos 12 meses, avaliando-se aspectos operacionais relacionados às práticas e estratégias utilizadas. A frequência de orientação de atividade física foi de 86,2% (IC95% = 83,2-88,8%). O aconselhamento se caracterizou como uma prática breve, realizada em consultas individuais, voltadas para adultos e idosos e pessoas com morbidades. A estratégia mais utilizada foi orientar usuários a participarem de grupos de atividade física no Centro de Saúde (89,5%), e em relação ao método 5As, dar algum "conselho" foi a estratégia mais utilizada (99,0%), e a menos utilizada foi seguir estratégias (22,6%). Aconselhamento para atividade física tem sido baseado em uma prática breve, realizada em consultas individuais e focada em pessoas com morbidades e em adultos e idosos. As estratégias utilizadas parecem não abranger o cuidado integral dos usuários aconselhados.

Abstract This study aim to describe the characteristics and strategies of counseling for physical activity used by Primary Health Care (PHC) professionals. A survey was carried out with 587 (85.4% women) health professionals who work in PHC in Florianopolis, in the state of Santa Catarina, southern Brazil. Counseling carried out in the last 12 months was considered. Operational aspects related to counseling practices and strategies used for counseling were evaluated. The frequency of physical activity guidance was 86.2% (95%CI = 83.2-88.8%). Counseling was characterized as a brief practice, carried out in individual consultations, aimed at adults and the older adults and people with morbidities. The most used strategy was to guide users to participate in physical activity groups at the Health Center (89.5%) and in relation to the 5As method, giving some "advice" was the most used strategy (99.0%) and the least used. used was to follow strategies (22.6%). Counseling for physical activity has been based on a brief practice, carried out in individual consultations and focused on people with morbidities and on adults and the elderly. The strategies used do not seem to cover the full care of the advised users.

La obesidad infantil, un problema de salud que demanda urgentes intervenciones educativas

La obesidad constituye un problema de salud global que afecta no solo a adultos, sino también a niños y adolescentes, por lo cual se reconoce la necesidad de adaptar los programas de intervención educativa del Ministerio de Educación, en asociación con el Ministerio de Salud Pública, para su adecuación al universo infantil. Se ha demostrado en la práctica que la actividad física es un espacio idóneo para la inclusión educativa de todos los escolares; se ha pasado del paradigma de la integración al paradigma de la inclusión, donde todos disfrutan de una atención diferenciada según sus carencias. Es propósito de los autores comunicar acerca de una intervención educativa aplicada a niños de 9 años que presentan obesidad y sobrepeso, con acciones que modifican su estilo de vida y educan a la familia para enfrentar este alarmante problema de salud en dicho grupo etario.

Obesity is a global health problem that affects not only adults and older adults, but also children and adolescents, thus recognizing the need to adapt the educational intervention programs of the Ministry of Education, in partnership with the Ministry of Public Health, to adapt them to the children's universe. It has been demonstrated in practice that physical activity is an ideal space for the educational inclusion of all schoolchildren; we have moved from the paradigm of integration to the paradigm of inclusion, where everyone enjoys differentiated attention according to their needs. It is the authors' purpose to communicate about an educational intervention applied to 9-year-old children with obesity and overweight, with actions that modify their lifestyle and educate the family to face this alarming health problem in this age group.

Brazilian version of the Hammersmith Functional Motor Scale Expanded: cross-cultural adaptation and validation / Versão brasileira da Hammersmith Functional Motor Scale Expanded: adaptação transcultural e validação

Abstract Background The Hammersmith Functional Motor Scale Expanded (HFMSE) has been widely used to assess the motor function of patients with spinal muscular atrophy (SMA) older than 2 years, with the ability to sit and/or walk. Objective To translate, cross-culturally adapt and validate the HFMSE to Brazilian Portuguese. Methods The translation process and cross-cultural adaptation followed international guidelines recommendations. The reliability and applicability of the Brazilian version consisted of the application of the HFMSE (in Brazilian Portuguese) to 20 patients with types 2 and 3 SMA. Two examiners assessed the participants for interrater reliability, through the analysis of Kappa reliability agreement (k) and intraclass correlation coefficient (ICC). Results The HFMSE was successfully translated and cross culturally adapted to Brazilian Portuguese. Twenty participants with types 2 and 3 SMA were enrolled in the study (type 2 = 6; type 3 = 14). The ICC for the total score showed very high reliability (ICC =1.00), and the reliability of each of the items individually was considered excellent (Kappa > 0.80). Conclusion The Brazilian version of the HFMSE proved to be valid and reliable for the evaluation of SMA patients older than 2 years with the ability to sit and/or walk.
