Resumo O objetivo do artigo é analisar a clareza e as medidas de engajamento das publicações sobre câncer bucal nos perfis do Instagram dos órgãos oficiais de saúde no Brasil. Realizou-se um estudo infodemiológico com 81 perfis. Foram coletados dados sobre classificação do conteúdo, conta e mídia, abordagem do tema, número de postagens, curtidas, comentários, visualizações e hashtags. A clareza das publicações educativas foi avaliada pela versão brasileira do Clear Communication Index (BR-CDC-CCI). A análise dos dados envolveu a correlação de Spearman e o teste de Mann-Whitney (α = 5%). Foram encontradas 775 publicações sobre câncer bucal. O escore médio do BR-CDC-CCI foi 69,8 (DP = 15,5). A clareza das informações foi adequada em 9,5% das publicações educativas. Correlações positivas foram encontradas entre o número de curtidas e engajamento (comentários [r = 0,49], visualizações [r = 0,96]), número de hashtags (r = 0,13) e ano de publicação (r = 0,21). Publicações do Ministério da Saúde apresentaram escore do BR-CDC-CCI significativamente maior do que os demais perfis (p = 0,01). As publicações sobre câncer bucal foram correlacionadas com engajamento, ano de publicação e número de hashtags.

Abstract Objective: To investigate the usefulness, reliability, quality, and content of Portuguese-language YouTube videos on COVID-19. Material and Methods: Three keywords selected on Google Trends were searched on YouTube, and the 60 first videos listed with each term were analyzed. Two calibrated researchers evaluated the reliability (DISCERN Modified Scale), the quality (Global Quality Score - GQS), and the usefulness of videos for the users (COVID-19 Specific Score - CSS). The number of views, likes, and engagement were also analyzed. The data were evaluated by the Mann-Whitney test and Spearman correlation (α=5%). Results: 59 videos were included. The average scores of quality, reliability, and usefulness were 3.0 (±1.1), 3.2 (± 0.8), and 1.5 (± 0.9), respectively. Two-thirds of the videos (64.4%) had low/moderate quality, and the majority (76.2%) were about signs and symptoms. The numbers of views (p=0.005), likes (p=0.006), and engagement (p=0.014) were significantly higher in moderate/good quality videos. The number of comments (p=0.007), duration of videos (p=0.004), and the DISCERN score (p<0.001) were significantly higher in videos made by health professionals. The general quality of the videos was positively correlated to the CSS scores, number of views, likes, and engagement (p<0.05). Conclusion: Most videos had moderate quality and reliability and low usefulness for the users. Objective Portugueselanguage Portuguese language COVID19.

ABSTRACT Objective: To determine the occurrence of hyposalivation in Brazilian adults and its association with individual determinants, such as the use of medications, systemic conditions, smoking, and alcohol consumption. Material and Methods: A cross-sectional study with 402 adults was developed. Information was collected on sociodemographic and general health characteristics, and sialometry was performed with stimulated salivary flow. It indicated low salivary flow when ≤ 0.7 mL/min. Bivariate and multivariate analyses were conducted using a decision tree (p<0.05). Results: The sample was comprised predominantly of women (68.2%) aged ≤ 29 years (25.4%). Most participants did not use medication (56.7%). Among systemic diseases, the most cited was hypertension (25.1%). More than a third of the participants presented hyposalivation (40.3%), being associated with the following variables: age between 50 to 59 years (p=0.011), female sex (p<0.001), menopause (p=0.001), use of alcohol (p=0.033), systemic disease (p=0.002) and medication use (p<0.001). In multivariate analysis, in addition to sex (p<0.001) and hypertension (p=0.005), an association was also found between hyposalivation and diabetes (p=0.014). Conclusion: Factors associated with hyposalivation in adults were sex and the presence of hypertension or diabetes.

ABSTRACT The aim of this study was to undertake a cross-cultural adaptation of the eHealth Literacy Scale (eHEALS) instrument to measure digital health literacy of Brazilian adolescents. eHEALS is a scale consisting of 8 items that measure self-perception related to the consumption of electronic health information. This is a methodological study of cross-cultural adaptation, conducted out from February 2022 to June 2022. The following steps were carried out: a) assessment and adequacy of cultural equivalence by a committee of experts; b) back-translation; c) synthesis of back-translations; d) cognitive testing with 42 Brazilian adolescents, using cognitive interviews with probing questions. All items that were difficult to understand were adapted to the (language) context of Brazilian adolescents. Cronbach’s alpha coefficient for eHEALS-BrA was 0.81 and, if one of the items were excluded from the instrument, it ranged from 0.75-0.81. This version of the eHEALS proved to be culturally well-adapted to the context of Brazilian adolescents, and has the potential to measure digital health literacy in this population after having its validation confirmed through psychometric analyses. crosscultural cross (eHEALS adolescents selfperception self perception information 202 experts b backtranslation back translation back-translation c backtranslations translations back-translations d 4 questions language (language Cronbachs Cronbach s eHEALSBrA BrA 081 0 81 0.8 0.750.81. 075081 0.75 0.81. 75 0.75-0.81 welladapted well analyses 20 08 0. 750 0.750.81 07508 075 0.7 7 0.75-0.8 2 0.750.8 0750 07 0.75-0. 0.750. 0.75-0 0.750 0.75-

Resumo Investigar determinantes individuais e contextuais associados ao bullying em escolares de 8 a 10 anos. Foi realizado estudo transversal com 739 crianças. As crianças responderam uma pergunta sobre episódios de bullying relacionado a saúde bucal, um questionário sobre ansiedade infantil e disfunção orofacial. Os responsáveis forneceram informações sobre características sociodemográficas, distúrbios do sono e alfabetismo em saúde bucal. Examinadores treinados avaliaram as crianças para diagnóstico da cárie dentária pelo International Caries Detection and Assessment System, má oclusão por meio do Dental Aesthetic Index, disfunção orofacial pelo Nordic Orofacial Test-Screening e traumatismo dentário (Critério de Andreasen) (Kappa>0,80). As variáveis contextuais foram tipo de escola e renda mensal do bairro escolar. Estatística descritiva foi utilizada para caracterização da amostra. Modelos de regressão de Poisson multinível não ajustados e ajustados (p<0,05) foram usados. A prevalência do bullying foi 13,3%. Após análise ajustada a má oclusão (RP=1.59; IC95%:1.03-2.44) e a ansiedade (RP=1.79; IC95%:1.10-2.93) permaneceram associados ao bullying. Em relação ao contexto, a menor renda mensal do bairro da escola foi associada ao bullying (RP=1.75; IC95%:1.12-2.72). Má oclusão e ansiedade influenciaram a presença do bullying. A menor renda mensal do bairro escolar foi um determinante contextual importante para o aumento da prevalência de bullying. 1 anos 73 bucal sociodemográficas System Index TestScreening Test Screening Critério Andreasen Kappa>0,80.

Abstract Investigate individual and contextual determinants associated with bullying in schoolchildren eight to ten years of age. A cross-sectional study was conducted with 739 schoolchildren, who answered a question about episodes of bullying related to oral health and questionnaires addressing childhood anxiety and orofacial dysfunction. The guardians provided information on sociodemographic characteristics, sleep disorders, and oral health literacy. Trained examiners assessed the children for the diagnosis of dental caries using the International Caries Detection and Assessment System, malocclusion using the Dental Aesthetic Index, orofacial dysfunction using the Nordic Orofacial Test-Screening and traumatic dental injury (Andreasen criteria) (Kappa> 0.80). The contextual variables were the type of school and the monthly income of the school neighborhood. Descriptive statistics was performed to characterize the sample and unadjusted and adjusted (p <0.05) multilevel Poisson regression models were run. The prevalence of bullying was 13.3%. After the adjusted analysis, malocclusion (PR=1.59; 95%CI:1.03-2.44) and anxiety (PR=1.79; 95%CI:1.10-2.93) remained associated with bullying. In terms of context, the monthly income of the neighborhood of the school was associated with bullying (PR=1.75; 95%CI:1.12-2.72). Malocclusion and anxiety influenced the occurrence of bullying. A lower average income in the school neighborhood was an important contextual determinant for the increase in the prevalence of bullying. age crosssectional cross sectional 73 characteristics disorders literacy System Index TestScreening Test Screening Andreasen criteria Kappa> Kappa (Kappa 0.80. 080 0.80 . 0 80 0.80) p <0.05 005 05 run 133 13 3 13.3% analysis PR=1.59 PR159 PR 1 59 (PR=1.59 95%CI1.032.44 95CI103244 CI 95%CI 1.03 2.44 95 03 2 44 95%CI:1.03-2.44 PR=1.79 PR179 79 (PR=1.79 95%CI1.102.93 95CI110293 1.10 2.93 10 93 95%CI:1.10-2.93 context PR=1.75 PR175 75 (PR=1.75 95%CI1.122.72. 95CI112272 1.12 2.72 12 72 95%CI:1.12-2.72) 7 08 0.8 8 <0.0 00 13.3 PR=1.5 PR15 5 (PR=1.5 CI1 032 95%CI1.032.4 95CI10324 95CI 103 1.0 244 2.4 9 4 95%CI:1.03-2.4 PR=1.7 PR17 (PR=1.7 102 95%CI1.102.9 95CI11029 110 1.1 293 2.9 95%CI:1.10-2.9 122 95%CI1.122.72 95CI11227 112 272 2.7 95%CI:1.12-2.72 0. <0. 13.

RESUMO Objetivo: O presente estudo teve como objetivo investigar associações entre os motivos da busca por serviços odontológicos, considerando a última consulta odontológica de adolescentes, e suas características escolares, status socioeconômico e bucal e alfabetização em saúde bucal. Métodos: Foi realizado um estudo transversal com 746 adolescentes de 15–19 anos em Campina Grande (Paraíba), Brasil. Os pais/responsáveis responderam a um questionário socioeconômico. Os adolescentes responderam a um questionário de saúde bucal e à versão brasileira do Rapid Estimate of Adult Literacy in Dentistry (rápida estimativa de alfabetização de adultos em odontologia). As características do contexto escolar foram investigadas por meio de análise de cluster, utilizando tipo de escola e taxa de retenção escolar. Os adolescentes foram examinados clinicamente para diagnóstico de cárie dentária por dois dentistas (κ>0,80), usando os critérios de Nyvad, nas instalações das escolas. Os dados foram submetidos à regressão logística multinível robusta para amostras complexas (α=5%). Resultados: No nível individual, a baixa escolaridade da mãe (razão de probabilidade [OR] 1,06; IC95% 1,01–1,10), alfabetização em saúde bucal inferior (OR 0,99; IC95% 0,98–0,99) e cárie dentária (OR 1,09; IC95% 1,01–1,18) permaneceram associados ao motivo da última consulta odontológica. O ambiente escolar também foi associado ao desfecho (OR 1,07; IC95% 1,00–1,15). Conclusão: Escolaridade materna com menos de oito anos de estudo, baixa literacia em saúde bucal, cárie cavitada e ambiente escolar desfavorável foram associados à procura por tratamento odontológico.

Methods: A cross-sectional study was conducted with 746 adolescents aged 15–19 years in Campina Grande (Paraíba), Brazil. Parents/guardians answered a socioeconomic questionnaire. Adolescents answered a questionnaire on oral health and the Brazilian Rapid Estimate of Adult Literacy in Dentistry. Features of the school environment were investigated through cluster analysis, using type of school and school grade retention. Adolescents were clinically examined for dental caries diagnosis by two dentists (κ>0.80), using the Nyvad criteria, in school facilities. Data were submitted to robust multilevel logistic regression for complex samples (α=5%). Results: At the individual level, low maternal schooling (odds ratio [OR] 1.06; 95%CI 1.01–1.10), low oral health literacy (OR 0.99; 95%CI 0.98–0.99), and dental caries (OR 1.09; 95%CI 1.01-1.18) remained associated with the reasons for the last dental appointment. The school environment was also associated with the outcome (OR 1.07; 95%CI 1.00–1.15). Conclusion: Maternal schooling of less than eight years of study, low oral health literacy, cavitated caries, and unfavorable school environment were associated with seeking dental treatment.

RESUMO Objetivo: O presente estudo teve como objetivo investigar associações entre os motivos da busca por serviços odontológicos, considerando a última consulta odontológica de adolescentes, e suas características escolares, status socioeconômico e bucal e alfabetização em saúde bucal. Métodos: Foi realizado um estudo transversal com 746 adolescentes de 15–19 anos em Campina Grande (Paraíba), Brasil. Os pais/responsáveis responderam a um questionário socioeconômico. Os adolescentes responderam a um questionário de saúde bucal e à versão brasileira do Rapid Estimate of Adult Literacy in Dentistry (rápida estimativa de alfabetização de adultos em odontologia). As características do contexto escolar foram investigadas por meio de análise de cluster, utilizando tipo de escola e taxa de retenção escolar. Os adolescentes foram examinados clinicamente para diagnóstico de cárie dentária por dois dentistas (κ>0,80), usando os critérios de Nyvad, nas instalações das escolas. Os dados foram submetidos à regressão logística multinível robusta para amostras complexas (α=5%). Resultados: No nível individual, a baixa escolaridade da mãe (razão de probabilidade [OR] 1,06; IC95% 1,01–1,10), alfabetização em saúde bucal inferior (OR 0,99; IC95% 0,98–0,99) e cárie dentária (OR 1,09; IC95% 1,01–1,18) permaneceram associados ao motivo da última consulta odontológica. O ambiente escolar também foi associado ao desfecho (OR 1,07; IC95% 1,00–1,15). Conclusão: Escolaridade materna com menos de oito anos de estudo, baixa literacia em saúde bucal, cárie cavitada e ambiente escolar desfavorável foram associados à procura por tratamento odontológico.

Abstract The present study aimed to perform the cross-cultural adaptation of the Digital Health Literacy Instrument (DHLI) for native Brazilian Portuguese-speaking adolescents (DHLI-BrA). Cross-cultural adaptation consisted of the following steps: translation, assessment, and adjustments by the expert committee to ensure cultural equivalence; back-translation, and synthesis of back-translations. Cognitive testing was then performed in a pretest with adolescents using cognitive interviews with probing questions on the item's understanding interpretation and response options. Cronbach’s alpha coefficient and McDonald’s omega were used to estimate the instrument’s reliability. Forty-two Brazilian adolescents participated in the study (mean age: 16.0 ± 2.0 years; range: 13 to 19 years). Items that were difficult to understand were adapted to the context of Brazilian adolescents. Cronbach’s alpha coefficient and McDonald’s omega for the 21 items of the DHLI-BrA were, respectively, 0.79 and 0.80. Cronbach’s alpha coefficient for the subscales of the self-report instrument was 0.53-0.79 (range), demonstrating good reliability in the total instrument and moderate reliability in the subscales. This study provides the cross-cultural adapted version of the Digital Health Literacy Instrument (DHLI), which is an instrument for measuring digital Health literacy, for use in Brazilian adolescents (DHLI-BrA). crosscultural cross DHLI (DHLI Portuguesespeaking Portuguese speaking DHLIBrA.

ABSTRACT To investigate individual and contextual factors associated with seeking treatment for traumatic dental injuries. A cross-sectional study was conducted with 739 pairs of guardians and children. Guardians answered a questionnaire addressing sociodemographic characteristics, seeking treatment for a tooth injury in the child, and the Oral Health Literacy-Adult Questionnaire. Descriptive analysis and unadjusted and adjusted multilevel Poisson regression analysis (p<0.05). The prevalence of seeking treatment for traumatic dental injury was 44.7%. Sociodemographic variables associated were white skin of the child (PR = 1.30; 95% CI: 1.08-1.76), mother’s age older than 35 years (PR = 1.70; 95% CI: 1.50-1.90), married parents (PR = 1.93; 95% CI: 1.70-2.23), guardians with more than eight years of schooling (PR = 2.00; 95% CI: 1.76-2.23), with adequate oral health literacy (PR = 3.33; 95% CI: 3.01-3.62) and the daily use of electronic devices by the child (PR = 1.26; 95% CI: 1.02-1.50). On the contextual level, attending a private school (PR = 1.77; 95% CI: 1.02-3.05) and the number of primary care units with oral health teams in the school district (PR = 1.78; 95% CI: 1.12-2.38) remained associated. Among the children who suffered TDI, adequate oral health literacy on the part of the parents stood out among the factors associated with seeking treatment. injuries crosssectional cross sectional 73 characteristics LiteracyAdult Literacy Adult Questionnaire p<0.05. p005 p p<0.05 . 0 05 (p<0.05) 447 44 7 44.7% PR 1.30 130 1 30 95 CI 1.081.76, 108176 1.08 1.76 , 08 76 1.08-1.76) mothers mother s 3 1.70 170 70 1.501.90, 150190 1.50 1.90 50 90 1.50-1.90) 1.93 193 93 1.702.23, 170223 2.23 2 23 1.70-2.23) 2.00 200 00 1.762.23, 176223 1.76-2.23) 3.33 333 33 3.013.62 301362 3.01 3.62 01 62 3.01-3.62 1.26 126 26 1.021.50. 102150 1.02 02 1.02-1.50) level 1.77 177 77 1.023.05 102305 3.05 1.02-3.05 1.78 178 78 1.122.38 112238 1.12 2.38 12 38 1.12-2.38 TDI p00 p<0.0 (p<0.05 4 44.7 1.3 13 9 081 1.081.76 10817 108 1.0 176 1.7 1.08-1.76 17 501 1.501.90 15019 150 1.5 190 1.9 5 1.50-1.90 19 702 1.702.23 17022 223 2.2 1.70-2.23 2.0 20 762 1.762.23 17622 1.76-2.23 3.3 013 3.013.6 30136 301 3.0 362 3.6 6 3.01-3.6 1.2 021 1.021.50 10215 102 1.02-1.50 023 1.023.0 10230 305 1.02-3.0 122 1.122.3 11223 112 1.1 238 2.3 1.12-2.3 p0 p<0.

Abstract The study analyzed the clarity of publications on human papillomavirus (HPV) in the Instagram profiles of official Brazilian health agencies. An infodemiological study analyzed publications on HPV in the 81 Instagram profiles selected from the Health Ministry, States’ Health Departments, and dental councils and associations. The following data were collected: classification of content, type of profiles, type of media, how the content was addressed, number of posts, frequency, likes, comments, viewings, and hashtags, and how the HPV vaccine was addressed. The clarity of the educational publications was assessed using the Brazilian version of the Clear Communication Index (BR-CDC-CCI). Data analysis was performed with Spearman’s correlation and the Mann-Whitney test (p < 0.05). A total of 504 publications on HPV were found. The average number of likes was 528.3 (SD = 2388.2) and the average BR-CDC-CCI score was 67.1 (SD = 14.1). The quality and clarity of the information was considered adequate (BR-CDC-CCI score ≥ 90) in 6.9% of the publications. A weak positive correlation was found between the number of likes and both the BR-CDC-CCI score (r = 0.195) and number of posts (r = 0.124). Publications from the Health Ministry had a significantly higher BR-CDC-CCI score (72.9) compared to the other profiles analyzed (p = 0.01). Most publications concerned government actions, had low engagement, and written educational information was of low clarity and quality. However, the effort to reach the population was evident, with an increase in publications over the years.

Abstract The aim of the present study was to investigate predictors of malocclusion in Brazilian schoolchildren eight to ten years of age based on a causal directed acyclic graph model. A cross-sectional study was conducted with 739 schoolchildren eight to ten years of age. Parents/guardians provided information on sleep disorders of the child (Sleep Disturbance Scale for Children) and family characteristics (Family Adaptability and Cohesion Evaluation Scale). The diagnosis of malocclusion was performed by four trained examiners using the Dental Aesthetic Index. Control variables were selected using a directed acyclic graph. Descriptive analysis was performed, followed by robust logistic regression analysis for complex samples (α = 5%). The following variables were associated with malocclusion in the final model: sleep disorders (OR = 2.61; 95%CI: 2.43–2.86), mouth breathing (OR = 1.04; 95%CI: 1.02–1.99), non-nutritive sucking habits (OR = 2.45; 95%CI: 2.37–4.85), and obesity (OR = 1.54; 95%CI: 1.02–2.33).

Abstract The aim of the present study was to investigate the impact of oral health literacy (OHL) on conceptions of care and behaviors related to COVID-19. The sample came from two preliminary cross-sectional studies that determined the level of OHL of parents/guardians of six-to-12-year-old children in two major Brazilian cities (Curitiba and Belo Horizonte). Functional OHL was measured using the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) and the Health Literacy Dental Scale (HeLD-14) for the evaluation of interactive OHL. Participants were recruited through e-mail, social media, and telephone contact. The questionnaire on conceptions of care and behaviors related to COVID-19 was created based on the guidelines of the World Health Organization. Two hundred nineteen individuals participated in the study. There was no significant difference in socioeconomic and demographic variables and in the medians of BREALD and HeLD-14 between the two cities (P>0.05). Higher levels of functional OHL were associated with an appropriate conception that individual care affects collective care (P=0.038), but with an inappropriate conception of seeking medical assistance in cases of mild symptoms (P=0.030). Higher levels of interactive OHL were related to social distancing behavior in the city of Curitiba (P=0.049) and in the overall sample (P=0.040). It is concluded that functional OHL was associated with two of the investigated conceptions about COVID-19, while interactive OHL was associated with social distancing behavior. These data may suggest that different dimensions of the OHL can have an impact on different aspects of coping with the pandemic. (OHL COVID19.

RESUMO Introdução O bruxismo do sono (BS) é definido como movimentos involuntários da mandíbula caracterizados por ranger e apertar os dentes. Objetivo Verificar se o cronotipo e a qualidade do sono estão associados ao autorrelato de BS em graduandos de Odontologia. Método Um estudo transversal com 214 estudantes de uma universidade pública do Nordeste do Brasil. Os participantes responderam ao Morningness-Eveningness Questionnaire para identificar os cronotipos e outro questionário sobre aspectos diários em que foram coletadas informações sobre qualidade do sono, autorrelato de bruxismo do sono, uso de pílulas para dormir, ronco, concentração nas atividades diárias, energia ao acordar. Resultados A prevalência de autorrelato do bruxismo do sono foi de 11,0%. No modelo final, o cronotipo noturno (OR = 23,00; 95% IC: 2.36-223.84, p = 0,007), o hábito de roncar (OR = 3,12; 95% IC: 1.31-7.39, p = 0,01) e o baixo nível de energia ao acordar pela manhã (OR = 2,37; 95% IC: 1.96-5.58, p = 0,04) estiveram associados com o autorrelato de BS. Conclusão O cronotipo noturno, a presença do ronco e a baixa energia ao se levantar pela manhã influenciaram o autorrelato de bruxismo do sono entre os estudantes de graduação em Odontologia.

ABSTRACT Background Sleep bruxism (BS) is defined as involuntary jaw movements characterized by grinding and clenching teeth. Objective To verify the association between chronotype, sleep quality, and self-reporting of BS in dental students. Method A cross-sectional study was conducted with 214 undergraduate dental students at a public university in northeast Brazil. The participants answered the Munich Chronotype Questionnaire for the identification of chronotype and another questionnaire regarding daily aspects to collect information about sleep quality, self-reported sleep bruxism, the use of sleeping pills, snoring, concentration during daily activities and energy upon waking. Results The prevalence of self-reported sleep bruxism was 11.0%. In the final model, the eveningness chronotype (OR = 23.00; 95% CI: 2.36-223.84, p = 0.007), habitual snoring (OR = 3.12; 95% CI: 1.31-7.39, p = 0.01) and low energy upon waking in the morning (OR = 2.37; 95% CI: 1.96-5.58, p = 0.040) were associated with self-reported sleep bruxism. Conclusion The evening chronotype, presence of snoring, and low energy when waking up in the morning influenced self-reporting of sleep bruxism among undergraduate dental students.

Abstract The aim of the present study was to investigate whether possible awake bruxism (AB) is associated with the use of electronic devices and the practice of sports in schoolchildren aged eight to ten years. A cross-sectional study was conducted with 739 students in public and private schools in the city of Campina Grande, Brazil. Parents/guardians answered a questionnaire addressing sociodemographic data. The children answered questions about use of electronic devices, practice of sports, and AB. Statistical analysis involved robust logistic regression for complex samples (α = 5%). The prevalence of possible AB was 14.9%. Being female (OR = 1.71, 95%CI: 1.11–2.63), being the middle child (OR = 2.19, 95%CI: 1.14–3.88), having unmarried parents (OR = 1.73, 95%CI: 1.13–2.65), daily use of a cell phone/tablet/computer (OR = 1.82, 95%CI: 1.19–2.80), use of electronic devices for two or more hours per day (OR = 1.97, 95%CI: 1.35–2.86), and playing sports in and/or out of school (OR = 1.60, 95%CI: 1.18–2.52) remained associated with possible AB in the final model. The presence of possible AB was influenced by the use of electronic devices and the practice of sports among schoolchildren aged eight to ten years.
