Bidirectional Daily Associations Between Accelerometer-Measured Sleep and Physical Activity in Brazilian High School Students.

PURPOSE: This study analyzed day-to-day estimates of bidirectional associations between sleep parameters and intensity-specific physical activity and assessed whether the timing of physical activity influences these relationships. METHODS: The sample was comprised of 651 high school students (51.2% female, 16.33 [1.0] y old) from southern Brazil. Physical activity and sleep were measured using accelerometers. Multilevel models were applied to test associations of nocturnal total sleep time, onset, and efficiency with moderate to vigorous and light (LPA) physical activity. RESULTS: Higher engagement in moderate to vigorous physical activity and LPA was associated with increased total sleep time, and this effect was greater when physical activity was performed in the morning. Morning and evening LPA were associated with increased sleep efficiency and reduced total sleep time, respectively. Practice of LPA in the morning leads to early sleep onset, whereas evening LPA was associated with later onset. Higher total sleep time and later sleep onset were associated with lower moderate to vigorous physical activity and LPA on the following day. However, higher sleep efficiency was associated with increased LPA. CONCLUSION: The relationship between sleep parameters and physical activity is bidirectional and dependent on physical activity intensity and timing.

Cross-cultural adaptation and validation of the Quality of Life in School (QoLS) Questionnaire into Brazilian Portuguese.

The school is fundamental for the development of societies and caring for the student is part of the educational process. Reflections on collective health allowed the expansion of the vision of the concept of quality of life considering different social spaces and indicators. Thus, the aim of this study was to assess of some psychometric Properties of the Quality of Life in School instrument into Brazilian Portuguese (QoLS-BR) among elementary school students. The processes of translation, content evaluation, focus group and Confirmatory Factor Analysis (CFA) were carried out. Reproducibility analysis was performed by administering QoLS-BR to 30 students. The sample used for Internal Consistency and CFA comprised 434 students with a mean age of 12.31 years. High indices of language clarity, practical relevance, theoretical relevance, internal consistency, and reproducibility were obtained. In the AFC, adjustments were not necessary in the QoLS-BR model with four factors (RMSEA=0.065; TLI=0.959; CFI=0.962; SRMR=0.080) indicating that the indices were adequate when investigating all four domains. QoLS-BR has adequate psychometric indicators for investigating the quality of life in school.

Relationship between body composition and bone mass in normal-weight and overweight adolescents.

Adolescence is a period characterized by large accumulation of bone mass. Body composition is an important determinant of bone mass. This study aimed to assess the relationship of bone mass with lean mass (LM) and fat mass (FM) in normal-weight and overweight adolescents with consideration of sex, sexual maturation and physical activity covariates. A total of 118 adolescents (60 girls and 58 boys) aged between 10 and 14 years participated in the study. Individuals were classified as normal weight or overweight according to body mass index. Bone mineral density (BMD), bone mineral content (BMC), LM, and FM were measured by dual-energy X-ray absorptiometry. In normal-weight adolescents, LM (ß = 0.725, p < 0.001) and FM (ß = 0.185, p = 0.019) were associated with lumbar spine BMC, whereas in overweight adolescents only LM (ß = 0.736, p < 0.001) was associated with lumbar spine BMC. Furthermore, in the normal-weight group, FM and LM were associated with total body less head BMD (LM, ß = 0.792, p < 0.001; FM, ß = 0.257, p = 0.007) and lumbar spine BMD (LM, ß = 0.553, p < 0.001; FM, ß = 0.199, p < 0.035). In the overweight group, only LM was associated with total body less head BMD (ß = 0.682, p < 0.001) and lumbar spine BMD (ß = 0.528, p < 0.001). LM was the main predictor of bone mass in normal-weight and overweight adolescents. FM was associated with bone mass in normal-weight adolescents only. LM may be considered an important and useful marker in adolescents, when investigating bone health in this population. Activities that promote LM gain to reduce the risk of bone fractures and diseases in adulthood are recommended.

Young people's low back pain and awareness of postural habits: A cross-sectional study.

BACKGROUND: Young people tend to spend most of their time in activities involving inappropriate positions, which can promote musculoskeletal alterations and disorders. OBJECTIVE: To investigate the prevalence of low back pain (LBP) in young people and analyse its associations with daily postural habits. METHODS: Cross-sectional and retrospective study evaluating 679 Brazilian young people (15 to 18 years old), using questionnaires about LBP and awareness of postural habits. The prevalence values were calculated for the present moment, the last three months and throughout life. The Mann-Whitney U test and the Chi-square test were applied. RESULTS: The prevalence of LBP at the present moment was 27.2%, 57.7% over the last three months and 73.9% throughout life. Boys and girls presented significantly different values, a larger number of girls manifesting pain for the three moments. The associated postural habits were: turning the body, reduction of lumbar lordosis when seated, not placing the feet on the floor, crossing the legs when sitting in the classroom and at home, sitting or lying in an inappropriate position, and distributing the body asymmetrically on the legs when standing. CONCLUSIONS: Young people from 15 to 18 years of age show a high prevalence of low back pain. Inadequate postural habits adopted during everyday activities are associated with this complaint. These findings could contribute to the implementation of prevention and rehabilitation strategies.

Socioenvironmental factors and behaviors associated with negative self-rated health in Brazil.

The purpose of this study is to determine the factors associated with negative self-rated health in Brazil. The sample consisted of 5,259 adults from five representative capitals of the five regions of Brazil. Data collection was achieved in the following municipalities: Palmas (North Region), João Pessoa (Northeast Region), Goiânia (Central-West Region), Vitória (Southeast Region) and Florianópolis (South Region). For the analysis of the data, Binary Logistic Regression for determine the factors associated with negative self-rated health was used. Negative self-rated health was identified in 31.43% of Brazilians. The factors that were significantly associated were bad air quality, does not have public spaces for leisure, older age group, insufficient salary to cover expenses, a rare practice of physical exercises, does not perform healthy eating, active commuting for study or employment and commuting time for above 30 minutes, dissatisfaction with health services and still, not working, not looking for a job and finally, reside in some Brazilian regions. The study presents the importance of socioenvironmental and behavioral factors for the self-rated health of Brazilian adults, as well as it shows high rates of negative self-rated health compared to other studies.

ADHD Comorbid With Major Depression on Parents and Teachers Perceptions.

Objective: Examine the Strengths and Difficulties Questionnaire (SDQ) responses of parents and teachers for children with ADHD comorbid with major depressive disorder (MDD), with an emphasis on determining how well the respondent groups' responses correlate, and how well the results obtained perform as predictors of clinical diagnosis. Method: The SDQ was completed by parents and teachers of (n = 215 participants, 7-12 years old) in ADHD, MDD, ADHD + MDD, and healthy control groups. Agreement between parent and teacher SDQs and their concordance with Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) diagnoses were assessed. Receiver operating characteristic (ROC) and Kappa concordance analyses were used to compare the groups with the health control group. Results: The comorbid group presented greater impairments than the ADHD, MDD, and control groups (p < .001). Conclusion: The presence of psychiatric comorbidity causes greater impairment for school children with ADHD. The SDQ has good sensitivity for detecting these children and correlates well with DSM diagnosis.

Social support from family and friends for physical activity in adolescence: analysis with structural equation modeling.

Social support is an important predictor for the maintenance of physical activity in adolescence. Thus, the social-ecological approach values the impact of individuals or groups interaction with available resources in the social environment for adopting an active lifestyle. This study analyzes social support from family and friends for adolescents to practice physical activity. Guided by the Social-Ecological Theory, an observational cross-sectional structural equations modeling was applied to 2,710 Brazilians adolescents aged from 14 to 18 years. We identified that the greater the social support from friends (ß = 0.30; RMSEA = 0.065; CFI = 0.953; TLI = 0.922; SRMR = 0.048) and family, the greater the adolescents physical activity (ß = 0.27; RMSEA = 0.015; CFI = 0.997; TLI = 0.995; SRMR = 0.013). However, support from both sources indicated no adequate adjustment values in the same study model. Our findings suggest that adolescents who perceive social support from family members or friends practice more physical activity, confirming that social support is important for physical activity promotion.

SUBJECTIVE SLEEP NEED AND DAYTIME SLEEPINESS IN ADOLESCENTS.

OBJECTIVE: To analyze the contribution of subjective sleep need for daytime sleepiness in adolescents, and to compare questions about sleep, age and body mass index between adolescents who considered to sleep enough and those who reported the need for more sleep. METHODS: This is a descriptive, epidemiological and cross-sectional study. Data collection was performed in August 2016, with 773 adolescents aged 14-19 years old, from Paranaguá, Paraná, Southern Brazil. The analysis included the following variables: time in bed, half-sleep phase, sleep need, social jetlag, daytime sleepiness, body mass index and physical activity. RESULTS: The prevalence of adolescents with subjective need for sleep was 73.0%, with an average need of 1.7 extra hours of sleep. These adolescents woke up earlier (p<0.001) and slept less on school days (p<0.001). The need for more sleep was associated with higher daytime sleepiness scores (rho=0.480; p<0.001) and with later half-sleep phase (rho=0.200; p<0.001). No correlation was identified between the sleep need and time in bed (rho=-0.044; p=0.225). The subjective sleep need was the variable with the greatest explanatory power for daytime sleepiness (24.8%; p<0.001). In addition, the less adolescents practiced physical activity, the higher their daytime sleepiness scores (rho=-0.117; p<0.001). CONCLUSIONS: The subjective sleep need has an important role in explaining daytime sleepiness among adolescents. Adolescents who needed to sleep more reported waking up early and experienced sleep deprivation during class days; they also woke up later on the weekends and experienced more daytime sleepiness, compared to those who believed they had enough sleep.

[Association between dissatisfaction with body image and health-related physical fitness among adolescents]. / Associação entre insatisfação com a imagem corporal e aptidão física relacionada à saúde em adolescentes.

The scope of this study was to estimate the prevalence of dissatisfaction with body image and verify the association between dissatisfaction with thinness or with overweight and health-related physical fitness components among adolescents. Participants included 1058 adolescents (570 girls and 488 boys), with mean age of 16.3 (±1.0) years. The investigated variables were dissatisfaction with body image (Figure Rating Scale), and health-related physical fitness: body fat (skin folds), muscle strength (handgrip strength) and cardiorespiratory fitness (mCAFT test). The association of body image and the health-related physical fitness variables was tested by Multinomial Regression analysis. The prevalence of body dissatisfaction was 75.2% (girls = 79.5%; boys = 70.3%). Girls and boys with high body fat were less likely to be dissatisfied with thinness and more likely to be dissatisfied with overweight. Those who needed to improve muscle strength and cardiorespiratory fitness were more likely to be dissatisfied with thinness and with overweight, respectively. In conclusion, physical fitness was associated with body image, with the adolescents with less healthy conditions of the components being more dissatisfied.

O objetivo deste estudo foi estimar a prevalência de insatisfação com a imagem corporal e verificar a associação entre a insatisfação pela magreza e pelo excesso de peso e componentes da aptidão física relacionada à saúde em adolescentes. Participaram 1.058 adolescentes (570 moças e 488 rapazes), com média de idade de 16,3(± 1,0) anos. As variáveis investigadas foram a insatisfação com a imagem corporal (escala de silhuetas), e as relativas à aptidão física relacionada à saúde: adiposidade corporal (dobras cutâneas), força muscular (preensão manual) e aptidão cardiorrespiratória (teste mCAFT). A associação entre a imagem corporal e as variáveis de aptidão física foi testada por meio da Regressão Multinomial. A prevalência de insatisfação corporal foi de 75,2% (moças = 79,5%; rapazes = 70,3%). Moças e rapazes com adiposidade corporal elevada tiveram menor chance de insatisfação pela magreza e maior chance de insatisfação pelo excesso de peso. Os que necessitavam melhorar a força muscular e a aptidão cardiorrespiratória tiveram maior chance de insatisfação pela magreza e pelo excesso de peso, respectivamente. Conclui-se que a aptidão física relacionada à saúde esteve associada à imagem corporal, sendo que os adolescentes com níveis menos saudáveis dos diferentes componentes foram os mais insatisfeitos.

Status social subjetivo e a qualidade de vida em estudantes do ensino fundamental / Subjective social status and quality of life of elementary school adolescents

Este estudo teve o objetivo de descrever e relacionar a qualidade de vida e o Status Social Subje-tivo (SSS) na escola e nas aulas de educação física em estudantes do ensino fundamental. Estudo transversal com 875 estudantes do ensino fundamental do município de Palhoça, Santa Catarina. A qualidade de vida foi analisada por meio do Pediatric Quality of Life InventoryTM versão 4.0 (PedsQL 4.0) e o SSS foi investigado por meio da escala de MacArthur adaptada para estudantes brasileiros para o ambiente escolar e aulas de educação física. Os domínios da qualidade de vida que apresen-taram menores pontuações foram os relacionados aos sentimentos (61,4 pontos) e à escola (70,3 pontos). A questão "eu sinto raiva" obteve menor pontuação (50,8 pontos), seguida da questão "eu me preocupo com o que vai acontecer comigo" (53,1 pontos), ambas do domínio sentimentos. Um total de 37,1% e 25% dos estudantes apresentaram percepção de SSS negativa nas aulas de educação física e na escola, respectivamente. Os estudantes com a percepção negativa de SSS tiveram piores escores de qualidade de vida. Diante dos resultados destacam-se as pontuações baixas de qualidade de vida, especialmente com relação aos sentimentos e escola por parte dos estudantes, e os percentuais altos de percepção negativa de SSS.

This study aimed to describe and associate the quality of life and Subjective Social Status (SSS) at school and in Physical Education classes among elementary school students. Cross-sectional study with 875 elementary school students in the city of Palhoça ­ Southern Brazil. Quality of life was analyzed using the Pediatric Quality of Life InventoryTM version 4.0 (PedsQL 4.0) and SSS was investigated using the MacArthur scale, which was adapted for Brazilian students for the school environment and Physical Education classes. The quality of life domains that presented the lowest scores were those related to feelings (61.4 points) and schools (70.3 points). The question "I feel angry" received the lowest score (50.8 points), followed by the question "I worry about what will happen to me" (53.1points), both from the feelings domain. A total of 37.1% and 25% of students had a negative perception of SSS in Physical Education classes and at school, respectively. Students with a negative perception of SSS had worse quality of life scores. Given the results, the low quality of life scores stand out, especially in relation to students' feelings about school and the high percentages of negative perception of SSS

Construct validity and internal consistency in the Leisure Practices Scale (EPL) for adults. / Validade de construto e consistência interna da Escala de Práticas no Lazer (EPL) para adultos.

This study proposes and analyzes the construct validity and internal consistency of the Leisure Practices Scale (EPL). This survey seeks to identify the preferences and involvement in in different leisure practices in adults. The instrument was formed based on the cultural leisure content (artistic, manual, physical, sports, intellectual, social, tourist, virtual and contemplation/leisure). The validation process was conducted with: a) content analysis by leisure experts, who evaluated the instrument for clarity of language and practical relevance, which allowed the calculation of the content validity coefficient (CVC); b) reproducibility test-retest with 51 subjects to calculate the temporal variation coefficient; c) internal consistency analysis with 885 participants. The evaluation presented appropriate coefficients, both with respect to language clarity (CVCt = 0.883) and practical relevance (CVCt = 0.879). The reproducibility coefficients were moderate to excellent. The scale showed adequate internal consistency (0.72). The EPL has psychometric quality and acceptable values in its structure, and can be used to investigate adult involvement in leisure activities.

Este estudo propõe e analisa a validade de construto e a consistência interna da Escala de Práticas no Lazer (EPL). O instrumento busca identificar as preferências e o envolvimento em práticas nos diferentes contextos do lazer em adultos. A construção do instrumento deu-se a partir dos conteúdos culturais do lazer (artístico, manual, físico-esportivo, intelectual, social, turístico, virtual e contemplação/ócio). O processo de validação foi realizado com: a) Análise de conteúdo por especialistas em lazer, que avaliaram o instrumento quanto à clareza da linguagem e pertinência prática, o que permitiu o cálculo do coeficiente de validade de conteúdo (CVC); b) Reprodutibilidade em teste-reteste com 51 sujeitos para o cálculo do coeficiente de variação temporal; e c) Análise de consistência interna com 885 participantes. A avaliação de conteúdo apresentou coeficientes adequados, tanto com relação à clareza da linguagem (CVCt = 0,883), quanto à pertinência prática (CVCt = 0,879). Os coeficientes de reprodutibilidade foram de moderados a excelentes. A escala apresentou adequada consistência interna (0,72). A EPL apresentou qualidade psicométrica e valores aceitáveis em sua estrutura, podendo ser utilizada para investigar o envolvimento em práticas nos diferentes conteúdos do lazer de adultos.

[Insufficient levels of physical activity of adolescents associated with sociodemographic, environmental and school factors]. / Níveis insuficientes de atividade física de adolescentes associados a fatores sociodemográficos, ambientais e escolares.

This study investigated the associations between the level of physical activity with sociodemographic, environmental and academic factors of adolescents. Two thousand five hundred and forty-five adolescents aged between 14 and 18 from Florianópolis and neighboring cities participated in this study. The short version of the International Physical Activity Questionnaire (IPAQ) was used. The prevalence of inactive adolescents was 48.6%, being higher among females (53.9%). For girls, physical inactivity was associated with the lack of appropriate and free places for physical activity (OR = 1.30 95% CI 1.05 to 1.82), with no influence of other variables. For boys who had no professional activity (OR = 1.54 95% CI 1.14 to 2.08), less educated mothers (OR = 0.41 95% CI 0.27 to 0.75), or graduate mothers (OR = 0.35 95% CI 0,17- 0,73), living in major cities (OR = 1.64 95% CI 1.17 to 2.31) and low socioeconomic classification when compared to the average (OR = 0.69 95% CI 0.49 to 0.97) were more prone to physical inactivity. It was observed that the socio-demographic variables were associated with the inactive behavior of boys and environmental variables were associated with the physical inactivity of girls. Among the academic factors, only having to repeat a year was associated with inactivity, and only for girls.

Este estudo investigou as associações entre o nível de atividade física com os fatores sociodemográficos, ambientais e escolares de adolescentes. Participaram 2.545 jovens de 14 a 18 anos dos municípios da Grande Florianópolis. Foi utilizada a versão curta do Questionário Internacional de Atividade Física (IPAQ). A prevalência de jovens inativos foi de 48,6%, sendo maior no sexo feminino (53,9%). Para as moças, a inatividade física esteve associada com a falta de lugares apropriados e gratuitos para a prática de atividade física (OR = 1,30 IC95%1,05-1,82), independente da influência das outras variáveis. Já para os rapazes, aqueles que não possuíam atividade profissional (OR = 1,54 IC95%1,14-2,08), mães de menor instrução (OR = 0,41 IC95% 0,27-0,75) ou mães com ensino superior (OR = 0,35 IC95% 0,17- 0,73), pertencentes a cidades de grande porte (OR = 1,64 IC95%1,17-2,31) e classificação socioeconômica baixa quando comparada à média (OR = 0,69 IC95% 0,49-0,97), apresentaram maior chance de inatividade física. Observou-se que as variáveis sociodemográficas estiveram associadas ao comportamento inativo dos rapazes e às variáveis ambientais se associaram a inatividade física das moças. Já dentre os fatores escolares, apenas a reprovação escolar foi associada com inatividade, e somente para as moças.

Percepções sobre os espaços públicos de lazer, segurança e qualidade de vida dos brasileiros / Perceptions about brazilian's leisure public places, security and life quality

Objetivo: analisar as percepções sobre os espaços públicos de lazer, segurança e qualidade de vida dos adultos brasileiros. Método: a amostra foi composta por 5259 adultos, representando uma cidade de cada uma das cinco regiões brasileiras, sendo elas: Florianópolis (SC), Goiânia (GO), João Pessoa (PB), Palmas (TO) e Vitória (ES). Foi utilizado um questionário estruturado que foi aplicado por equipe treinada. A Regressão Logística Binária foi utilizada para identificar as razões de chances, sendo analisadas no modelo ajustado quando as variáveis atingissem o critério pré estabelecido de p<0,05. Resultados: Pelo menos um terço da amostra (35,2%) indicou percepção de qualidade de vida negativa. Demonstraram maior chance de apresentá-la aqueles que quase nunca ou nunca frequentavam espaços públicos de lazer e os que os percebiam como desagradáveis, insuficientes e inseguros e aqueles que não se sentiam seguros durante a noite e de dia em suas cidades. Conclusão: A partir das associações encontradas após análise ajustada, sugere-se que espaços públicos de lazer e segurança podem intervir na qualidade de vida, por isso recomenda-se soluções de incentivo e manutenção daqueles, de forma que incida positivamente na percepção desta.

Objective: To analyze the perceptions about public leisure spaces, safety and quality of life of Brazilian adults. Method: the sample consisted of 5,259 adults, representing a city in each of the five Brazilian regions, namely: Florianópolis (SC), Goiânia (GO), João Pessoa (PB), Palmas (TO) and Vitória (ES). Characterizing itself as a cross-sectional descriptive epidemiological research. The instrument applied in the research was the standardized questionnaire, called Public Opinion Research (POP). Binary Logistic Regression was used to identify the odds ratios, being analyzed in the adjusted model when the variables reached the pre-established criterion of p<0.05. Results: At least one third of the sample (35.2%) indicated a negative perception of quality of life. Those who almost never or never attended public leisure spaces and those who perceived them as unpleasant, insufficient and insecure and those who did not feel safe during the night and day in their cities showed a greater chance of presenting it. Conclusion: Based on the associations found after an adjusted analysis, it is suggested that public spaces for leisure and safety can intervene in the quality of life, so it is recommended solutions to incentive and maintain those, in a way that positively affects their perception.

A composição corporal de trabalhadores obesos está associada às barreiras para a atividade física no lazer? / Is the body composition of obese workers associated with the constraints to physical activity leisure?

O objetivo deste estudo foi associar a percepção de barreiras para atividade física no lazer (AFL) com o status de peso de trabalhadores industriários. Participaram 885 trabalhadores de ambos os sexos (515 mulheres). Além das barreiras à AFL, foram analisados o IMC auto referido e variáveis sociodemográficas. Estratificadas pelo status de peso, motivos como falta de interesse em praticar (p = 0,004), falta de habilidades físicas (p = 0,044), preocupação com a aparência durante a prática (p < 0,001) e medo de lesionar-se (p = 0,002) foram significantemente mais frequentes entre os obesos, em comparação aos eutróficos. Ainda, quanto maior o IMC de mulheres, mais barreiras para AFL são percebidas (r = 0,119; p = 0,009). Concluiu-se que a composição corporal é um fator que está associado às AFL de trabalhadores obesos. Além disso, em mulheres, o impacto da relação entre a percepção de barreiras e o status de peso parece maior.

The aim of this study was to associate the perception of barriers to leisure-time physical activity (LPA) with the industrial worker's weight status. 885 workers of both sexes (515 women) participated. In addition to barriers to AFL, self-reported BMI and sociodemographic variables were analyzed. Stratified by weight status, reasons such as lack of interest in practicing (p = 0.004), lack of physical skills (p = 0.044), concern with appearance during practice (p < 0.001) and fear of injury (p = 0.002) were significantly more frequent among obese compared to eutrophic individuals. Also, the higher the BMI of women, the more barriers to AFL are perceived (r = 0.119; p = 0.009). Is the body composition of obese workers associated with the constraints to physical activity leisure? Furthermore, in women, he impact of the relationship between perceived barriers and weight status appears to be greater.

Cultural adaptation and validation of the Sport Imagery Questionnaire for Children (SIQ-C) to the portuguese language / Adaptação cultural e validação do Sport Imagery Questionnaire for Children (SIQ-C) para a língua portuguesa

The aim of this study was to translate, adapt and validate the Sport Imagery Questionnaire for Children to Brazilian Portuguese. For this purpose, analyzes of reproducibility, internal consistency and confirmatory factor analysis were conducted. The final sample consisted of 521 athletes from 14 sports and ages 14 and 19 (M = 16.31, SD = 1.18). High indices of internal consistency (? = 0.870), reproducibility (0.824) and content validity were verified. In the confirmatory factor analysis, it was observed the appropriate global indexes of adjustment to the five-factor instrument model (RMSEA = 0.060; CFI = 0.90; TLI = 0.88; SRMR = 0.047). The translated instrument has adequate psychometric indicators to evaluate sport imagery, presents a reproducible factor structure and is a reliable test to measure the frequency of imagery use in Brazilian adolescent athletes.

Para tanto, foram realizadas análises de reprodutibilidade, consistência interna e análise fatorial confirmatória. A amostra final foi composta de 521 atletas praticantes de 14 modalidades esportivas e com idades entre 14 e 19 anos (M = 16,31, DP = 1,18). Foram verificados altos índices de consistência interna (? = 0,870), reprodutibilidade (0,824) e validade de conteúdo. Na análise fatorial confirmatória, foram observados os índices globais adequados de ajuste ao modelo do instrumento de cinco fatores (RMSEA = 0,060; CFI = 0,90; TLI = 0,88; SRMR = 0,047). O instrumento traduzido possui indicadores psicométricos adequados para avaliar a imagética no esporte, apresenta uma estrutura fatorial reproduzível e é um teste confiável para medir a frequência de uso de imagética em atletas adolescentes brasileiros.

Tradução e validação da leisure attitude scale para o português do Brasil / Translation and validation of leisure attitude scale to portuguese of Brazil

O presente estudo teve como objetivo traduzir para o português do Brasil e analisar a validade de conteúdo da Leisure Attitude Scale (LAS), propondo assim a versão brasileira do instrumento a Escala de Atitudes ao Lazer (EAL). Seguindo os critérios estabelecidos por Herdman, Fox-Rushby e Badia (1998) o método utilizado para a tradução e adaptação transcultural foi constituído pelas análises das equivalências conceitual, de itens, semântica, operacional e de mensuração. As etapas do processo foram: tradução e retrotradução, revisão técnica, avaliação da clareza da linguagem, pertinência prática e relevância teórica, aplicação dos instrumentos em grupo focal; reteste, e, por fim, a aplicação do instrumento finalizado em amostra de indivíduos adultos. Participaram do estudo adultos de ambos os sexos, trabalhadores do setor industriário da Grande Florianópolis ­ SC/Brasil. A amostra foi composta por 180 trabalhadores para análise da reprodutibilidade e 992 para os indicadores de consistência interna. Além disso, onze especialistas na área do lazer contribuíram para o processo de adaptação transcultural e validade de conteúdo do instrumento. Os especialistas atribuíram valores satisfatórios para a análise de conteúdo nos itens clareza e linguagem (CVCt = 0,818), pertinência prática (CVCt = 0,782) e relevância teórica (X = 3,91; DP = 0,83). Os índices de reprodutibilidade por meio da análise de correlação intraclasse em teste-reteste foram considerados adequados em todos os domínios da LAS (cognitivo = 0,785 - bom; emocional = 0,847 - ótimo; comportamental = 0,923 - excelente). Além disso, o Alpha de Cronbach apresentou valor de 0,958. Pode-se afirmar que a EAL se constitui em instrumento válido para a investigação das atitudes dos adultos face ao lazer nos domínios cognitivo, afetivo e comportamental, apresentando adequados indicadores psicométricos de validade, reprodutibilidade e consistência interna.

The purpose of this study was to translate to Brazilian Portuguese and to analyze the content validity of the Leisure Attitude Scale (LAS), thus proposing the Brazilian version of the instrument, the Brazilian Leisure Attitude Scale (EAL). Following the criteria established by Herdman, Fox-Rushby e Badia (1998), the methodology used for transcultural translation and adaptation, the conceptual, item, semantic, operational and measurement equivalences were respected. The stages of the process were: translation and back-translation, technical review, language clarity assessment, practical relevance and theoretical relevance, application of the focus group tools; retest, and, finally, the application of the completed instrument. The study included adults of both sexes, workers from the industrial sector of Greater Florianopolis - SC / Brazil. The sample consisted of 180 workers for analysis of reproducibility and 992 for indicators of internal consistency. In addition, eleven experts in the field of leisure have contributed to the process of cross-cultural adaptation and content validity of the instrument. The authors attributed satisfactory values to the content analysis in terms of clarity and language (CVCt = 0.818), practical relevance (CVCt = 0.782) and theoretical relevance (X = 3.91, SD = 0.83). The reproducibility indices by the intra-class correlation in test-retest were considered adequate in all domains of LAS (cognitive = 0.785- good, emotional = 0.847 - optimal, behavioral = 0.923 - excellent). In addition, Cronbach's Alpha presented a value of 0.958. We can say that the Brazilian version of LAS, the EAL is a valid instrument for the investigation of adults' attitudes towards leisure in the cognitive, affective and behavioral domains, presenting adequate psychometric indicators of validity, reproducibility and internal consistency.

ANALYSIS OF DAYTIME SLEEPINIESS IN ADOLESCENTS BY THE PEDIATRIC DAYTIME SLEEPINESS SCALE: A SYSTEMATIC REVIEW. / ANÁLISE DA SONOLÊNCIA DIURNA EM ADOLESCENTES POR MEIO DA PEDIATRIC DAYTIME SLEEPINESS SCALE: REVISÃO SISTEMÁTICA.

OBJECTIVE: To systematically review the use of the Pediatric Daytime Sleepiness Scale (PDSS) in the analysis of daytime sleepiness in children and adolescents. DATA SOURCE: The electronic databases PubMed and SciELO were consulted between 2003 and 2015. As inclusion criterion, studies were considered in English, Spanish and Portuguese, original articles of any type of design, articles with a sample of children and/or adolescents, articles that used the PDSS. Duplicate articles, articles with no relation to the theme, articles with another investigated population, and articles that the parents answered the instrument for their children were excluded. To find the material with these features, the terms "Daytime sleepiness" AND "adolescents" and "Daytime sleepiness" AND "children" were used in the searches. In addition, the descriptor "Pediatric Daytime Sleepiness Scale" was used to filter more specifically. DATA SYNTHESIS: Initially, 986 studies related to daytime sleepiness were identified. Considering the inclusion criteria, we analyzed 26 studies composed of 18,458 subjects aged 0 to 37 years. The diurnal sleepiness score ranged from 6.7±0.6 to 25.7±0.6 points. In general, all included studies investigated other sleep variables in addition to daytime sleepiness, such as: sleep duration, sleep quality, sleep hygiene or sleep disorders (narcolepsy and cataplexy), respiratory disorders, neurological and developmental disorders. CONCLUSIONS: There was a moderate use of PDSS to evaluate daytime sleepiness. This instrument allows the monitoring of factors that influence excessive daytime sleepiness in children and adolescents.

OBJETIVO: Revisar de modo sistemático a utilização da Pediatric Daytime Sleepiness Scale (PDSS) na análise da sonolência diurna em crianças e adolescentes. FONTES DE DADOS: Foram consultadas as bases de dados eletrônicas PubMed e SciELO, no período delimitado entre 2003 e 2015. Como critério de inclusão, foram considerados estudos em inglês, espanhol e português; artigos originais de qualquer tipo de escopo, com amostra de crianças e/ou adolescentes e que utilizaram a PDSS. Foram excluídos artigos duplicados, sem relação com o tema, com outra população investigada, bem como aqueles em que os pais responderam o instrumento pelos seus filhos. Para encontrar o material dentro desses critérios, foram utilizados nas buscas os seguintes termos: "Daytime sleepiness" AND "adolescents" e "Day time sleepiness" AND "children". Além disso, utilizou-se o descritor "Pediatric Daytime Sleepiness Scale" para fazer uma filtragem mais específica. SÍNTESE DOS DADOS: Inicialmente, identificaram-se 986 pesquisas relacionadas à sonolência diurna. Considerando os critérios de inclusão, foram analisados 26 estudos compostos por 18.458 sujeitos com idades de 0 a 37 anos que responderam à PDSS. A pontuação da escala da sonolência diurna variou de 6,7±0,6 a 25,7±4. Em geral, todos os estudos incluídos investigaram, além da sonolência diurna, outras variáveis do sono, como: duração, qualidade, higiene ou distúrbios do sono (narcolepsia e cataplexia), patologias respiratórias, neurológicas e do desenvolvimento. CONCLUSÕES: Verificou-se moderada utilização da PDSS para avaliar a sonolência diurna. Esse instrumento permite o acompanhamento de fatores que influenciam a sonolência diurna excessiva em crianças e adolescentes.

Comparação de avaliação de medidas indiretas e associação com medida subjetiva de capacidade aeróbia / Comparison of assessment of indirect measures and association with subjective measure of aerobic capacity

Este estudo teve como objetivo comparar a avaliação da resistência aeróbia avaliada pelos testes de McArdle e Conconi e associar as medidas indiretas com a percepção subjetiva por meio da Escala de Capacidade Percebida (ECP). Foram recrutados 29 participantes, 17 homens e 12 mulheres, com idades iguais ou maiores de 18 anos da região de São José, Santa Catarina. Após os recrutamentos foram analisados variáveis como sexo, idade, estatura, massa corporal, frequência cardíaca e esforço físico por meio dos testes de banco de McArdle e Conconi, além da capacidade percebida por meio da ECP. A média da pontuação da ECP foi de 9,72 (DP = 1,60). O Índice de Correlação Intraclasse entre os dois testes foi considerando excelente (r = 0,939; p < 0,001). Além disso, ambas análises apresentaram associação com a variável desfecho. No entanto, o poder explicativo da Regressão Linear, considerando como variável independente o VO2max a partir do deste de McArdle foi maior (45,3%). Assim, recomenta-se a utilização da tabela de referência deste teste para identificação do VO2máx a partir da percepção subjetiva pela ECP. Desta forma, a ECP pode ser uma ferramenta valiosa na avaliação, prescrição de exercícios e em estudos epidemiológicos por sua fácil e rápida aplicabilidade em adultos ativos fisicamente

This study aimed to compare the assessment of aerobic resistance evaluated by the McArdle and Conconi tests and to associate the indirect measures with the subjective perception through the Rating of Perceived Capacity (RPC). 29 participants were recruited, 17 men and 12 women, aged 18 years or older from the region of São José-SC. After recruitment, variables such as gender, age, height, body mass, heart rate and physical effort were analyzed using the McArdle and Conconi bench tests, in addition to the perceived capac-ity through the ECP. The mean ECP score was 9.72 (SD = 1.60). The Intraclass Correlation Index between the two tests was considered excellent (r = 0.939; p < 0.001). In addition, both analyses were associated with the outcome variable. However, the explanatory power of Linear Regression, considering VO2max as an independent variable from McArdle's, was higher (45.3%). Thus, it is recommended to use the reference table of this test to identify the VO2max from the subjective perception by the ECP. In this way, ECP can be a valuable tool in the evaluation, exercise prescription and in epidemiological studies due to its easy and quick easy applicability in physically active adults

Socioenvironmental factors and behaviors associated with negative self-rated health in Brazil

Abstract The purpose of this study is to determine the factors associated with negative self-rated health in Brazil. The sample consisted of 5,259 adults from five representative capitals of the five regions of Brazil. Data collection was achieved in the following municipalities: Palmas (North Region), João Pessoa (Northeast Region), Goiânia (Central-West Region), Vitória (Southeast Region) and Florianópolis (South Region). For the analysis of the data, Binary Logistic Regression for determine the factors associated with negative self-rated health was used. Negative self-rated health was identified in 31.43% of Brazilians. The factors that were significantly associated were bad air quality, does not have public spaces for leisure, older age group, insufficient salary to cover expenses, a rare practice of physical exercises, does not perform healthy eating, active commuting for study or employment and commuting time for above 30 minutes, dissatisfaction with health services and still, not working, not looking for a job and finally, reside in some Brazilian regions. The study presents the importance of socioenvironmental and behavioral factors for the self-rated health of Brazilian adults, as well as it shows high rates of negative self-rated health compared to other studies.
