WEB OF TRANSFORMATIONS: impact of multicomponent intervention on the relationship between sociodemographic indicators, changes in body composition, cardiorespiratory fitness and biochemical markers in adolescents with overweight and obesity.

The study aims to analyze the relationships between changes after multicomponent intervention in sociodemographic indicators, body composition, cardiorespiratory fitness and biochemical markers in overweight/obese adolescents. Quasi-experimental study with 33 overweight/obese adolescents (17 in the intervention group (IG) and 16 in the control group (16)), in which the GI participated in the multicomponent intervention for 24 weeks. Sociodemographic indicators, body composition, cardiorespiratory fitness and biochemical markers were evaluated. Network analysis was performed using JASP software. In GI, the reduction in %BF proved to be the variable with greater connectivity and strength in the network compared to the control network. Changes in %BF were related to changes in ACR, BMI and leptin. It is concluded that the reduction in %BF is the most important variable in network relationships after the intervention, suggesting that the greater the reduction in %BF, the greater the effect on variables such as BMI, ACR and leptina.

Compliance with the 24-h movement behaviors guidelines among urban and rural Brazilian preschoolers.

BACKGROUND: The importance of movement behaviors for health is well-known, although few studies have examined the compliance with movement guidelines in preschoolers from different living contexts. This study reported the compliance with the 24-h movement behaviors guidelines among low-income Brazilian preschoolers from rural and urban areas, according to age. METHODS: A total of 453 preschoolers (n = 222 urban), aged between 3 and 5 years, provided physical activity (PA) data (Actigraph wGT3X). Sleep duration, and screen time were parent-reported. Preschoolers were classified as compliant/non- compliant with the 24-h movement guidelines, according to age. The association between prevalence of compliance with the recommendations and the children's living setting were estimated (SPSS; 27.0). RESULTS: Preschoolers were active (mean = 299.19 ± 76.42; and 369.76 ± 95.56 min/day in urban and rural areas, respectively), though moderate-to-vigorous physical activity (MVPA) time was below the 60 daily minutes recommended in both urban and rural settings (mean = 38.39 ± 21.36; and 47.32 ± 24.28, respectively). None of the urban children complied with the three recommendations simultaneously, while in the rural area, only 2.6% were compliant. Single movement behaviors compliances in the urban setting were 6.8%, 28.8% and 5.4% for PA, sleep, and screen time, respectively; while for rural settings were 16.5%, 21.2%, and 7.4%. Living in the rural area was related to the compliance with PA recommendation for the 5-year-old preschoolers. CONCLUSION: In both urban and rural Brazilian areas, very few preschoolers are compliant with the guidelines, and more than one third of the children do not comply with any of the recommendations. Strategies and programs to promote compliance with movement behaviors guidelines should consider children's living setting and their age groups.

Stigma and knowledge about autism in Brazil: A psychometric and intervention study.

LAY ABSTRACT: To promote the full inclusion of autistic people, we must change the knowledge and attitudes of non-autistic individuals. Unfortunately, access to autism information and support remains limited in Brazil, and stigma is also common. Brazilian researchers reached out to a researcher in the United States to co-develop Brazilian surveys to measure autism stigma and knowledge. Together, they made Brazilian versions of stigma and knowledge surveys which autistic people in the United States had helped make. They also adapted an online autism training used in other countries with help from three Brazilian autistic people and the mother of an autistic child. They used the new measures to see if the autism training improved autism stigma and knowledge among Brazilians. The surveys, called EARPA and ECAT in Brazil, were translated into Portuguese in a previous study. In the first study in this article, 532 Brazilians completed the stigma measure and 510 completed the knowledge measure. The researchers used exploratory graph analysis, which uses the connections between items in a survey to understand which items belong together. Seventy-nine Brazilians participated in the training. They were mostly white, female university students. The EGA showed that the stigma survey measured one big idea while the knowledge survey measured four ideas: diagnosis/cause; socio-communicative development; stimming and special interests; and autism in adulthood. Both scales are promising and may be helpful in future Brazilian and cross-cultural studies about autism. Participants reported more knowledge and less stigma after the autism training, which has been found in other countries too.

What are the correlates of intention to be physically active in Brazilian adolescents? A network analysis.

OBJECTIVE: The current study aimed to explore the association of individual characteristics, social and environmental factors - school and region - in the intention to be physically active in Brazilian adolescents. METHODS: This is a cross sectional study based on the third edition of the National School Health Survey. The study included a total of 53,937 adolescents. To assess the intention to be physically active, only who engaged in less than 300 min of physical activity per week were included. Participants were asked: "If you had the opportunity to practice physical activity most days of the week, what would your attitude be?" Individual characteristics, physical activity domains, social factors, school, and regional environments were used as exposures. Network analysis was utilized to evaluate the associations. RESULTS: We observed that boys had higher intentions to be physically active compared to their peers, as did adolescents who perceived themselves as fat. In addition, students from private schools show a higher intention to regularly engage in physical activities, and in general, private schools offer more extracurricular physical activities. CONCLUSION: In conclusion, individual factors such as sex and body image perception, and environmental factors such as school administrative dependency and availability of extracurricular activities had a significant contribution to the intention to be physically active among Brazilian adolescents.

A network analysis involving mental difficulties, cognition, physical fitness, 24-hour movement components, fatness, and sociodemographic factors in children.

Background: Evidence supports the beneficial linear influence of diverse lifestyle behaviors on brain health since childhood; however, multiple behaviors -and not only one-simultaneously affect such outcomes. Therefore, the aim was to explore the multivariate relationship through a network analysis among mental difficulty and cognitive function with physical fitness (PF), 24-h movement components, fatness, and sociodemographic factors in children. Methods: Cross-sectional study involved 226 children (52.2 % boys) aged between six and 11 years. Mental difficulties were evaluated through the Strengths and Difficulties Questionnaire and cognitive function by the Raven's Colored Progressive Matrices Test. The body mass index and PF were assessed according to the procedures suggested by the Proesp-Br, while moderate-to vigorous-intensity physical activity (MVPA) using accelerometry. The socioeconomic level, sleep, and screen time were evaluated by questionnaires. A network analysis was carried out to evaluate the associations among variables and establish centrality measures. Results: Age and PF moderated the negative relationship between cognitive function and MVPA. Furthermore, the direct and inverse relationship between cognitive function and mental difficulties appears to be affected by the 24-h movement components. Finally, age, PF, and screen time are the nodes with higher values of expected influence, indicating more sensitivity to interventions for decreasing mental difficulty and improving cognitive function. Conclusion: Mental health and cognitive function were moderated by the multivariate interaction among age, PF, and the three 24-h movement components. Nonetheless, centrality measures from the network analysis suggest that PF, MVPA, and screen time are crucial nodes in order to implement future interventions.

The subject-environment interplay between runners from different Brazilian macro-regions.

Purpose: Our purpose was to investigate the interplay between runners and their environment using a network approach. Methods: This cross-sectional study sampled Brazilian runners of both sexes, from the five macro-regions of the country. An electronic questionnaire was used to obtain information regarding age, sex, training volume, socio-economic level, place of residence, and running pace. Environmental indicators (public illumination, pavement, sidewalk, and green areas) were collected from available public information. Descriptive statistics were presented in mean (SD), and frequency (%). A network analysis was performed to evaluate the association between individual and environmental characteristics. Statistical analyses were performed in the JASP, considering p < 0.05. Results: At North and Mid-West regions, public illumination presents the highest values for the expected influence (1.74 and 1.56), while in Northeast and Southeast, sidewalks present the highest values (2.13; 0.91). For betweenness centrality, in North, Northeast, and Mid-West regions, residency in the capital of a state presented a hub. In contrast, pavement, and training volume present higher values in the South and Southeast. Network topologies are different. Conclusion: Public illumination (North and Mid-West) and sidewalk (Northeast, Southeast) were the most important variables for runners. Continental size countries need specific approaches to improve physical activity levels and health outcomes that consider the cultural, historical, and environmental background.

Paths towards a healthier BMI among short and adequate sleepers: A pathway network analysis considering movement behaviors in low-income preschoolers.

INTRODUCTION: Short sleep duration has been seen as a predictor of higher body mass index (BMI) in youth. Sleep duration varies substantially along early childhood, and the paths towards a healthier BMI, considering the other movement behaviors (physical activity-PA and screen time) are unexplored in preschoolers. AIM: To construct a sleep-BMI model to capture the direct and indirect paths to intervening towards a healthier BMI, according to low-income preschoolers' compliance with the other movement behaviors. METHODS: Two hundred and seventy two preschoolers (4.5 ± 0.0; 138 boys) participated in the study. Sleep and screen time (ST) were assessed in a face-to-face interview with primary caregivers. PA was assessed using accelerometer (wGT3X-BT). Preschoolers were categorized as compliant or not with sleep, screen time, total and moderate to vigorous PA recommendations. BMIz-score was calculated according to preschoolers' sex and age. All the assessed variables, besides sex and age were included in a Network Pathway Analysis (NPA) according to age as nodes. RESULTS: At 3 years old, a direct and negative path between sleep-BMIz score was observed. At four and 5 years old, this relationship became positive. Further, girls were more compliant with sleep, ST and total PA recommendations. Total PA (TPA) showed the highest expected influence value in the general, 3 and 4 years old NPA. CONCLUSION: The NPA analysis showed different directions for the relationship between sleep and BMIz score, according to age. Intervention strategies to a healthier BMI among preschoolers compliant or not with sleep recommendations should focus in increasing TPA.

Related-factors of social support for students' physical activity in a network perspective / Fatores relacionados ao suporte social para atividade física de estudantes em uma perspectiva de rede

This study investigates the relationship between social support and moderate to vigorous physical activity, as well as the possible relationships between social support and socioeconomic status, gender and body mass index. Cross-sectional study with a non-randomized sample of 71 students (boys and girls) aged 7 to 12 and their parents or legal guardians. Social support and socioeconomic status were assessed using validated questionnaires. Height and body mass measurements were used for the body mass index equation. Moderate to vigorous physical activity was measured by accelerometers. The associations between all variables were tested by a network analysis. Moderate to vigorous physical activity is negatively correlated with socioeconomic status, body mass index and a question from the social support questionnaire: "How many times in the last week have you watched your child be physically active?". We observed a positive correlation between moderate to vigorous physical activity with gender and a question from the social support questionnaire: "How many times in the last week did you provide transport for your child's physical activity?". Thus, moderate to vigorous physical ac-tivity has a negative correlation with socioeconomic status, body mass index and the variable "parents sometimes observe their child to be physically active", and parents who provide transportation for the child to practice physical activity. In future, it is import to consider the network analysis in the intervention studies to promote adolescents' physical activity

Este estudo investiga a relação entre suporte social e atividade física moderada-vigorosa, bem como as possíveis relações entre suporte social e nível socioeconômico, gênero e índice de massa corporal. Estudo transversal com amostra não randomizada de 71 escolares (meninos e meninas) de 7 a 12 anos e seus pais ou responsáveis. Apoio social e nível socioeconômico foram avaliados por meio de questionários validados. Medidas de altura e massa corporal foram usadas para a equação do índice de massa corporal. Atividade física moderada-vigorosa foi medida por acelerômetros. As associações entre todas as variáveis foram testadas por uma análise de rede. A atividade física moderada a vigorosa está negativamente correlacionada com o nível socioeconômico, índice de massa corporal e uma questão do questionário de apoio social: "Quantas vezes na última semana você observou seu filho ser fisicamente ativo?". Observou-se correlação positiva entre atividade física moderada-vigorosa com o gênero e uma questão do questionário de apoio social: "Quantas vezes na última semana você forneceu transporte para a atividade física de seu filho?". Assim, a atividade física moderada-vigorosa tem correlação negativa com o nível socioeconômico, índice de massa corporal e a variável "os pais às vezes observam que seu filho é fisicamente ativo, e pais que fornecem transporte para a criança praticar atividade física. No futuro, é importante considerar a análise de rede nos estudos de intervenção para promover a atividade física em adolescentes

Fatores associados aos comportamentos ativo e sedentário em adolescentes brasileiros: uma análise de redes / Factors associated with active and sedentary behaviors in Brazilian adolescents: a network analysis

O presente estudo verificou a associação entre variáveis sociodemográficas, características da esco-la, nível de atividade física (AF) e comportamento sedentário (CS) em adolescentes brasileiros. A amostra foi composta por 71.903 adolescentes entre 13 e 16 anos (52,8% meninas), matriculados no último ano do ensino fundamental, em escolas públicas e privadas do Brasil, participantes da terceira edição da Pesquisa Nacional da Saúde do Escolar (PeNSE). As informações foram recolhidas através de questionário. O tempo de AF na aula de Educação Física e extra aula de Educação Física, o tempo em deslocamento ativo e o tempo em CS foram associados às variáveis sociodemográficas (tipo de município, local da escola, escolaridade da mãe, percepção de insegurança, idade e sexo) e características da escola (tipo de escola e quadra disponível para uso). Utilizou-se a análise de rede. Quanto ao comportamento ativo, a topologia de rede mostrou que os meninos são mais ativos do que as meninas, principalmente na AF extra aula de Educação Física. Além disso, os resultados revelaram um maior tempo de AF na aula de Educação Física para os meninos, estudantes cujas mães apresentavam maior escolaridade, matriculados em escolas privadas e com quadra disponível para uso. Os estudantes matriculados em escolas públicas apresentaram maior tempo de AF em deslocamento ativo. Quanto ao CS, jovens do contexto urbano apresentaram maior exposição quando comparados aos pares do contexto rural. Conclui-se que as características sociodemográficas e da escola estão relacionadas com os comportamentos dos adolescentes brasileiros em todos os domínios da AF e no CS

The present study aimed to verify the association of sociodemographic correlates and school characteristics with levels of physical activity (PA) and sedentary behavior (SB) of Brazilian adolescents. The sample consisted of 71,903 adolescents between 13 and 16 years old (52.8% girls), enrolled in the last year in public and pri-vate elementary schools of Brazil, participants of the third edition of the National Survey of School Health (PeNSE). The time of PA in Physical Education class and extra Physical Education class, time in active commuting and time in SB were related to sociodemographic variables (type of municipality, place where the school is located, mother's schooling, perception of insecurity, age and gender) and school characteristics (type of school, block available for use). Data were analyzed using network analysis. The network topology showed that boys are more active than girls, especially in extra Physical Education`s PA. In addition, boys, students whose mothers have higher education, enrolled in private schools, which have a court available for use, have a positive association with longer time spent in PA in physical education classes. Students enrolled in public schools had a positive association with time spent in active commuting PA. As for SB, young people from the urban context are more exposed to SB than rural context. It was concluded that sociodemographic correlates and characteristics of the school were associated with all domains of the physical activity and sedentary behavior

How Do Health, Biological, Behavioral, and Cognitive Variables Interact over Time in Children of Both Sexes? A Complex Systems Approach.

The present study examined gender differences in health, physical activity, physical fitness, real and perceived motor competence, and executive function indicators in three time points, and analyzed the dynamic and non-linear association between health, biological, behavioral, and cognitive variables in children followed over time. A total of 67 children (aged between six and 10 years) were followed during two years and split into two cohorts (six to eight years old: C1; eight to 10 years old: C2). Data regarding health, physical activity, real and perceived motor competence, physical fitness, and executive function indicators were obtained according to their respective protocols. Comparison tests and network analysis were estimated. Significant gender differences were found in both cohorts. The emerged networks indicated different topologies in both cohorts. No clusters were observed between the variables in C1, and there was a greater number of interactions at eight years of age. Sparse networks were observed in children aged eight and 10 years in C2, and greater connectivity was observed at nine years of age between health, physical fitness, motor competence, and physical activity indicators. This study showed that there are non-linear dynamic relationships between health, biological, behavioral, and cognitive variables over time during child development.

Investigating the Construct Validity and Reliability of the Test of Motor Competence Across Iranians' Lifespan.

Motor competence (MC) has been extensively examined in children and adolescents, but has not been studied among adults nor across the lifespan. The Test of Motor Competence (TMC) assesses MC in people aged 5-85 years. Among Iranians, aged 5-85 years, we aimed to determine the construct validity and reliability of the TMC and to examine associations between TMC test items and the participants' age, sex, and body mass index (BMI). We conducted confirmatory factor analysis (CFA) to evaluate the TMC's factorial structure by age group and for the whole sample. We explored associations between the TMC test items and participant age, sex, and BMI using a network analysis machine learning technique (Rstudio and qgraph). CFA supported the construct validity of a unidimensional model for motor competence for the whole sample (RMSEA = 0.003; CFI = 0.998; TLI = 0.993) and for three age groups (RMSEA <0.08; CFI and TLI >0.95). Network analyses showed fine motor skills to be the most critical centrality skills, reinforcing the importance of fine motor skills for performing and participating in many daily activities across the lifespan. We found the TMC to be a valid and reliable test to measure MC across Iranians' lifespan. We also demonstrated the advantages of using a machine learning approach via network analysis to evaluate associations between skills in a complex system.

Cross-cultural adaptation of the web-based executive functioning questionnaire for Brazilian sample (Webexec-BR).

The Web-based Executive Functioning Questionnaire (Webexec) is a brief scale developed to assess executive functions via online format. It has been used in different contexts, but its adaptation to other cultures is still restricted. This study aimed to perform a cross-cultural adaptation of the Webexec for a Brazilian sample considering the psychometric properties of the scale. This study used a sample of 295 Brazilian participants, with a mean age equal to 20.69 (SD = 6.030). This is a longitudinal study with reapplication of the scale six weeks after the test phase. Classical and contemporary methods were applied to analyze the psychometric properties of the Webexec. The results showed that the scale presented excellent psychometric properties for the Brazilian version, considering validity evidence based on the content and internal structure of Webexec, as well as reliability and precision. However, it is considered that other relational and experimental studies should be carried out with a larger sample size and for different population groups.

Biological, behavioral, and social correlates of executive function in low-income preschoolers: Insights from the perspective of the networks.

Behavioral, biological, and social correlates may be related to the association between executive function (EF) and physical activity (PA), when considering such variables as an integrated and non-linear system. Thus, the aim of the present study was to investigate the relationships between EF, PA and associated correlates in low-income preschoolers according to a network perspective. Thus, 142 preschoolers of both sexes, age 3-to-5-years-old (51% girls) were analyzed. Light, moderate and vigorous PA, cardiorespiratory fitness (CRF), body mass index, family income, preterm birth, presence of siblings, presence of other children at home and the child's primary caregiver were assessed. Our results showed that EF was positively associated with age (b = 0.47), child's primary caregivers (b = 0.37), moderate PA (b = 0.30) and CRF (b = 0.25). Negative associations were seen with preterm birth (b = -0.50), vigorous PA (b = -0.34), presence of other children at home (b = -0.25), and sex (b = -0.33). The network's centrality indicators highlighted preterm birth and moderate PA as the most important variables in the network. Future interventions aiming to increase low-income preschoolers' EF should focus on increasing moderate PA, with special attention to preterm children.

Effects of a multicomponent intervention on cardiovascular risk factors in overweight children: a randomized clinical trial in light of complex systems.

Analyzing the effects of interventions from a theoretical and statistical perspective that allows understanding these dynamic relationships of obesity etiology can be a more efficient and innovative way of understanding the phenomenon's complexity. Thus, we aimed to analyze the pattern of cardiovascular risk factors between-participants, and the effects within-participants of a multidisciplinary intervention on cardiovascular risk factors in overweight children. This is a randomized clinical trial, and 41 participated in this study. A multicomponent intervention (physical activities, nutritional and psychological counseling) was performed for 10 weeks. Anthropometric and hemodynamics measurements, lipid and glucose profile, cardiorespiratory fitness, and left ventricular mass were evaluated. A network analysis was done. Considering patterns in the network at baseline, WC, WHR, BMI, and Fat were the main variables for cardiovascular risks. Group was the most critical variable in the within-participant network. Participating in a multicomponent intervention and decreasing body fat promoted beneficial cardiovascular factors.

Classification of the Effort Index and Biomechanical Overload in Natural Trails of UNESCO Global Geoparks-A Network Perspective of Trails of the Araripe UGG (NE Brazil).

Natural trails in UNESCO Global Geopark territories show strong salutogenic, inclusive and interactive characteristics as potentials and opportunities for ecosystem health. It is essential to provide information to inform the hiker as to the characteristics of the environment and the attractions and challenges of the route. Based on a network analysis methodology we aimed to identify the indicators of centrality and strength of connection in order to classify the effort index and biomechanical overload of the Araripe UNESCO Global Geopark trails in Brazil. The results showed strong connection and centrality of the variables related to the biomechanical overload in the effort index. In the trail of Pontal de Cruz the altimetric variation and the surface of the ground are highlighted in the biomechanical overload that presented a horizontal course equivalent 2.6 times larger than the presented distance. In Sítio Fundão trail, the surface of the ground also stood out, increasing the exposure in 36% of the presented distance. On the Missão Velha Waterfall trail, the variable that stood out was the biomechanical overload on the knee, equivalent to a horizontal increase of 28% of the measured distance. The methodology presented sought to optimise the mapping, management and consolidation of a network of natural trails aggregated to a high geotouristic, scientific, educational, cultural and well-being potential as presented in the Araripe UGG territory.

The Impact of a Swimming Training Season on Anthropometrics, Maturation, and Kinematics in 12-Year-Old and Under Age-Group Swimmers: A Network Analysis.

Understanding fluctuations and associations between swimming performance-related variables provide strategic insights into a swimmer's preparation program. Through network analysis, we verified the relationships between anthropometrics, maturation, and kinematics changes (Δ) in 25-m breaststroke (BREAST) and butterfly (FLY) swimming performance, before and after a 47-week swimming training season. Twenty age-group swimmers (n =11 girls: 10.0 ± 1.3 years and n = 9 boys: 10.5 ± 0.9 years) performed a 25-m all-out swim test (T25) in BREAST and FLY techniques, before and after 47 weeks. Three measures of centrality, transformed into a z-score, were generated: betweenness, closeness, and strength. Data were compared (t-test) and effect sizes were identified with Hedges' g. Large effect sizes were observed for swimming performance improvements in BREAST (32.0 ± 7.5 to 24.5 ± 3.8 s; g = 1.26; Δ = -21.9 %) and FLY (30.3 ± 7.0 to 21.8 ± 3.6 s; g = 1.52; Δ = -26.5 %). Small to moderate effect sizes were observed for anthropometric changes. Moderate effect size was observed for maturity offset changes (-2.0 ± 0.9 to -1.3 ± 1.0; g = 0.73; Δ = 50.9 ± 281 %). Changes in maturity offset, stroke rate (SR), and stroke length for both BREAST and FLY swimming speeds were highlighted by the weight matrix. For betweenness, closeness, and strength, changes in arm span (AS) (BREAST) and stroke length (FLY) were remarkable. The dynamic process of athletic development and the perception of complexity of fluctuations and associations between performance-related variables were underpinned, particularly for simultaneous swimming techniques in age-group swimmers.

TGMD-3 short version: Evidence of validity and associations with sex in Irish children.

This study examined the internal structure and evidence of validity of the Test of Gross Motor Development 3rd edition (TGMD-3) in primary school aged children. Participants (n = 1608, 47% girls, age range 5-11 years, mean age 9.2 ± 2.04) were recruited from Irish schools across twelve counties (56% rural, 44% urban). The TGMD-3 was used to measure FMS proficiency (Ulrich, 2020). A two-factor model (13 skills) was used and confirmatory indexes were calculated. The Bayesian criteria and the Composite Reliability were employed to evaluate alternative models. Relationships between the final model proposed with age, sex and BMI were calculated using a network analysis. Mplus 8.0 and Rstudio were used. A two-factor model (locomotion and object control) with adequate values (> 0.30) for the seven skills (gallop, hop, jump, two-hand strike, bounce, catch, overhand throw) presented excellent indexes. The skills with the highest indicator of strength centrality in the network were bounce and catch for both boys and girls and hop for boys and horizontal jump for girls. This study evidences the validity and reliability of the internal structure of the TGMD-3 and demonstrates that a short version of the TGMD-3, comprising seven skills is a valid measure of FMS in this population.

Psychometric Evidence of the Coping Inventory for Brazilian Paralympic Athletes in Competition Situations / Evidências Psicométricas do Inventário de Coping para Atletas Paralímpicos Brasileiros em Situação de Competição / Evidencias Psicométricas del Inventario de Afrontamiento para Atletas Paralímpicos Brasileños en Situación de Competición

Abstract Paralympic athletes face stressful situations in sports competitions daily, and assessing how they cope with these situations is important. This study aimed to evaluate the psychometric properties of the Coping Inventory for Brazilian Paralympic Athletes in Competition Situations. This study included 531 Brazilian Paralympic athletes aged 18 years or older, of both sexes, living in different Brazilian regions. They competed nationally or internationally and had physical or visual disabilities. Athletes with cerebral palsy were excluded. The participants answered a data questionnaire and the coping inventory. A confirmatory factor analysis confirmed a 12-theoretical dimension structure: six adaptive (Self-Reliance, Support-Seeking, Problem-Solving, Information-Seeking, Accommodation, Negotiation) and six maladaptive dimensions (Delegation, Social Isolation, Helplessness, Escape, Submission, and Opposition). Reliability indexes ranged between 0.60 and 0.94. The conclusion is that the instrument is reliable for assessing coping strategies among Brazilian Paralympic athletes.

A Network Perspective on the Relationship Between Moderate to Vigorous Physical Activity and Fundamental Motor Skills in Early Childhood.

BACKGROUND: The relationship between moderate to vigorous physical activity (MVPA) and fundamental motor skill (FMS) is inconsistent in early childhood, due to its complex and nonlinear characteristics. This study aimed to analyze the nonlinear relationships between MVPA, FMS, body mass index (BMI), sex, and age in preschoolers. METHODS: This cross-sectional study with preschoolers (n = 204; 4.0 [0.8] y old; 99 boys), provided objective physical activity data, FMS assessments, and BMI. The associations between MVPA, FMS, BMI, sex, and age were explored using the network analysis (RStudio and qgraph). RESULTS: Boys were more motor competent than girls in all FMS skills, while girls were more active than boys during the weekend. Older children were less active than their younger peers during these days. MVPA is weak and differently related to each FMS, and the leap skill emerged with the highest betweenness and strength values in the network. CONCLUSIONS: For the assessed preschoolers, when considering BMI, age, and sex, the relationships between MVPA and FMS are inconsistent, and leap emerged as the main variable. During early childhood, these variables are connected as part of a complex system in which each skill has a dynamic role within the emerging pattern.

Sociodemographic, Behavioral and Oral Health Factors in Maternal and Child Health: An Interventional and Associative Study from the Network Perspective.

Oral healthcare during pregnancy needs to be part of the assistance routine given to pregnant women by health professionals as a way to encourage self-care and strengthen the general health of the mother and the baby. The aim of this study was to evaluate the effectiveness of an integrated oral healthcare intervention for pregnant women and to analyze the association of sociodemographic, behavioral, oral health and general maternal and child health factors in prenatal care at usual risk in primary care in a city in the northeast of Brazil, in 2018-2019. A controlled, randomized, single-blinded community trial was conducted. The intervention group (IG) received dental assistance and collective health education actions in conversation circles, while the control group (CG) received the usual assistance. All pregnant women (146 in total, 58 from IG and 88 from CG) that took part in the trial answered a questionnaire and underwent a dental examination at the beginning of prenatal care and at the puerperal visit. To assess the effect of the intervention, a network analysis was used. The results have shown that being in the control group was associated with neonatal complications (0.89) and prematurity (0.54); the use of tobacco and alcohol are associated with high risk in initial and final oral health; lower educational level of the pregnant women implicates high risk for initial oral health (-0.19), final oral health (-0.26), pregnancy complications (-0.13), low birth weight (-0.23), prematurity (-0.19) and complications in the newborn (-0.14). Having a low family income (≤261.36 USD) has shown a high risk for initial oral health (-0.14), final oral health (-0.20) and prematurity (-0.15). The intervention based on integrated oral healthcare for pregnant women indicated that socioeconomic and behavioral factors must be considered as determinants for the quality of women and children's health and that multi-professional performance during prenatal care contributes to the positive outcomes of pregnancy.
