Time trends of physical inactivity in Brazilian adults from 2009 to 2017.

OBJECTIVE: The aim was to evaluate the changes in the prevalence of physical inactivity in the Brazilian adults from 2009-2017. METHODS: This study used a time-series research design based on the cross-sectional data of 462,498 Brazilian adults from 2009-2017. Participants were classified as physically inactive if they indicated not participating in physical activity in the last three months. The Prais-Winsten regression analyzed physical inactivity trends over time. RESULTS: The overall prevalence of physical inactivity was stable (p>0.05). Physical inactivity increased for women in four state capitals (annual growth rate: Goiânia 1.62%, Campo Grande 3.28%, Porto Velho 0.93%, and Vitória 2.09%) and decreased in one (annual growth rate: Rio Branco 4.50%). Physical inactivity decreased for men in four state capitals (annual growth rate: Campo Grande 4.72%, Natal 2.73%, São Luís 4.94%, and Rio Branco 2.95%). CONCLUSION: The physical inactivity among the Brazilian adults was stable between 2009 and 2017. Physical inactivity increased in women from Goiânia, Campo Grande, Porto Velho, and Vitória and decreased in women from Rio Branco and in men from Campo Grande, Natal, São Luís, and Rio Branco.

Validation of the teacher's health questionnaire for the brazilian context / Validação do questionário saúde docente para o contexto brasileiro

ABSTRACT The present study aimed at showing the cross-cultural adaptation and validation of the Spanish health questionnaire so-called Cuestionario de Salud Docente (CSD) for the Brazilian context with regard to the following variables: welfare (satisfaction and self-efficacy), and discomfort (musculoskeletal disorders, cognitive disorders, exhaustion and vocal cord disorders). Different steps were taken in order to ensure the quality of the translation and adaptation of the CSD concerning semantic, idiomatic, experiential and conceptual equivalence between the original items and the translated ones. The final sample of the pilot study consisted of 697 teachers, 168 men and 529 women, aged between 18 and 52 years who worked in 3 Early Childhood Education Centers, 9 Elementary Schools from the 1st to 5th grade, 04 Elementary Schools from the 6th to 9th grade, and 4 High Schools. Cohen's Kappa coefficient was used for assessing the temporal stability of the scores, and Cronbach's alpha test for the internal consistency of the dimensions and overall evaluation of the instrument, which showed a significant correlation. As a measuring instrument, the questionnaire is considered reliable to evaluate teacher's health, in addition to containing guidelines for further studies on welfare and discomfort variables of Brazilian teachers.

RESUMO O presente estudo apresenta a adaptação e validação transcultural do Questionário Saúde Docente (QSD) para o contexto brasileiro nas variáveis de bem-estar (satisfação e autoeficácia) e mal-estar (disfunções musculoesqueléticas, disfunções cognitivas, esgotamento e disfunções da voz). Foram realizadas distintas etapas para assegurar a qualidade da tradução e da adaptação do QSD no que se refere à equivalência semântica, idiomática, experiencial e conceitual entre os itens originais e traduzidos. A amostra final do estudo piloto foi constituída por 697 professores, sendo 168 do sexo masculino e 529 do feminino, com idades entre 18 e 52 anos, atuantes em 03 centros de Educação Infantil, 09 escolas do nível Ensino Fundamental de 1º ao 5º ano e 04 dos níveis Ensino Fundamental de 6º ao 9º ano e Ensino Médio. Para a análise da estabilidade temporal dos escores foi empregado o teste de Kappa e para a consistência interna das dimensões e da avaliação global do instrumento o teste de alfa de Cronbach, os quais apresentaram correlações satisfatórias. Como instrumento de medida, o questionário é considerado confiável para avaliar a saúde docente, além disso contém diretrizes para futuros estudos das variáveis associadas ao bem-estar e mal-estar de professores brasileiros.

Time trends of physical activity in Curitiba, Brazil: 2006-2015. / Tendência temporal da participação em atividade física no lazer na cidade de Curitiba, Brasil (2006-2015).

OBJECTIVE: The identification of the time trend of physical activity can help in the evaluation of the effectiveness of programs aimed at the promotion of physical activity at the population scope. To analyze the temporal trend of leisure time physical activity in adults living in the city of Curitiba (Brazil), from 2006-2015. METHODS: This is a cross-sectional study with 19,183 adults, obtaining information on duration, intensity and weekly frequency of leisure-time physical activity from the Surveillance System of Risk and Protection Factors for Chronic Diseases by Telephone Inquiry. Adults who reported participating in leisure time physical activity at least once a week in the three months prior to the survey were considered active. RESULTS: Men's leisure-time physical activity was stable overtime (p = 0.28), while it increased significantly among women (1.86% per year, 95%CI 0.55; 3.37; p = 0.02). Men reported less activities with weekly frequency of one to two times (-3.75% per year, 95%CI -6.72; -0.67; p = 0.03) but more with weekly frequencies of five to six times (7.42% per year, 95%CI 4.54; 10.38; p = 0.001). No changes were observed in the frequency of physical activity among women. CONCLUSION: Monitoring indicators of physical activity in the city of Curitiba can assist legislators in building policies to promote physical activity.

INTRODUÇÃO: A tendência temporal da participação em atividade física pode auxiliar na avaliação da efetividade de programas voltados à sua promoção no âmbito populacional. O estudo analisou a tendência temporal da participação em atividade física no lazer de adultos residentes na cidade de Curitiba, Paraná, Brasil, no período de 2006 a 2015. MÉTODOS: Estudo transversal com dados secundários de 19.183 participantes, obtidos junto ao Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (2006 a 2015).

Development and validation of the Brazilian Weight Teasing during Physical Activity Scale / Desenvolvimento e validação da Escala Brasileira de Provocações Referente ao Peso durante Atividade Física

Weight-related teasing is associated with loneliness, depression, eating disorders, and less physical activity. The purpose of the study was to develop the Brazilian Weight Teasing during Physical Activity scale (WTPAS-BR) and gather validity evidence to support its use in Brazilian adolescents. In phase 1, the prototype scale was adjusted. In phase 2, the prototype scale was cross-culturally adapted into the WTPAS-BR. In phase 3, the WTPAS-BR was psychometrically assessed. Adjustments to the prototype scale qualified items to measure weight-related teasing. A rigorous and systematic cross-cultural adaptation process translated, and assessed the content and adequacy of the WTPAS-BR among Brazilian adolescents. Based on the factorial assessment of WTPAS-BR, a one-factor model with four items was adopted. The WTPAS-BR showed adequate internal consistency, convergent validity, and test-retest reliability. Strong validity evidence supports the use of the WTPAS-BR to measure weight-related teasing occurring during physical activity in Brazilian adolescents...(AU)

A provocação relacionada ao peso corporal está associada com solidão, depressão, distúrbios alimentares e baixa atividade física. O objetivo deste estudo foi desenvolver a Escala Brasileira de Provocação relacionada ao Peso Corporal durante a Atividade Física (PPCAF-BR) e reunir evidências de validade para apoiar seu uso em adolescentes brasileiros. Na fase 1, ajustes foram feitos em uma escala protótipo. Na fase 2, esta escala foi adaptada culturalmente para a PPCAF-BR. Na fase 3, a PPCAF-BR foi avaliada psicometricamente.

Metabolic risk factors clustering among adolescents: a comparison between sex, age and socioeconomic status.

The aim was to compare the metabolic risk factors (MRF) between sex, age and socioeconomic status in a sample of adolescents from Curitiba, Brazil. A cross-sectional school-based study was conducted on 997 adolescents (429 boys) aged 12-17 years old from public schools. Total Cholesterol (TC), LDL-c, HDL-c, Triglycerides, Glycemia, Blood Pressure, waist circumference and body mass index were measured. Sex, age and socioeconomic status information was obtained using a questionnaire. Descriptive analyses, Fisher Exact and Chi-Square Tests were used to establish the sample's characteristics and the MRF comparison between variables. We found that 27.4% were classified as overweight/obese, almost half of them had TC and LDL-c classified as limitrophe/altered, with a difference between the sexes (p < 0.01), and that a higher percentage of altered values was seen among girls. The percentage of 3 and 4 or more MRF was 13.8% and 6.3%, respectively. In addition, 86.5% of the participants had at least one and 39.7% had at least two MRF. We conclude that there was a high percentage of overweight/obese, as well as a great number of subjects with altered TC and HDL-c. We also pointed out the large percentage of aggregated metabolic risk factors in both sexes. Strategies to reduce metabolic risk factors are required.

Resumo O objetivo do estudo foi comparar os fatores de risco metabólicos (FRM) entre sexo, idade e nível socioeconômico numa amostra de adolescentes de Curitiba, Brasil. O estudo transversal foi conduzido com 997 adolescentes da rede pública de ensino (429 meninos) com idade entre 12-17 anos. Coletaram-se dados de colesterol total (CT), LDL-c, HDL-c, triglicerídeos, glicemia, pressão arterial, circunferência de cintura e índice de massa corporal. Informações sobre sexo, idade e nível socioeconômico foram coletados por meio de um questionário. Foram utilizadas análises descritivas, teste exato de Fisher e Qui-quadrado. Observou-se que 27,4% foram classificados como sobrepeso/obeso, quase metade com CT e LDL-c limítrofes/alterados, com uma diferença entre os sexos (p < 0,01) e uma proporção maior entre as meninas. Verificou-se que as proporções de 3 e 4 ou mais FRM foram 13,8% e 6,3%, respectivamente. Adicionalmente, 86,5% e 39,7% dos adolescentes demonstraram ao menos um e dois FRM, respectivamente. Conclui-se que houve um elevado percentual de sobrepeso/obeso, assim como um grande número de sujeitos com CT e HDL-s alterados. Verificou-se um grande percentual de agregação de FRM em ambos os sexos. São necessárias estratégias para reduzir esses fatores de risco nessa fase da vida.

The relationship of movement skills with habitual and organized physical activity in seven and eight-year-old children / Associação entre habilidades motoras e atividade física habitual e organizada em crianças de sete e oito anos / Asociación entre habilidades motrices y actividad física habitual y organizada en niños de siete y ocho años

PURPOSE: To verify the association of motor skills with habitual and organized PA partici-pation, and sedentary behavior for males and females. METHODS: The study employed a cross-sectional design in a sample of seventy-six second graders from a public elementary school in a Midwestern State. RESULTS: Mann Whitney and t-tests indicated gender differ-ences in FMS and PA variables. Spearman correlation analyses demonstrated that habitual PA was correlated to total FMS, and manipulative skills for boys. For girls, a significant associa-tion was present in organized PA and locomotor skills. CONCLUSION: Choice of organized physical activity seems to influence the development of FMS and affect habitual PA behavior differently in boys and girls.

Associação entre dependência do exercício físico e percepção da qualidade de vida no basquetebol master brasileiro / Impact of physical exercise dependence on quality of life perception in Brazilian master basketball / Impacto negativo de la dependencia del ejercicio físico en la percepción de la calidad de vida en el baloncesto veterano de Brasil

Resumo O objetivo do presente estudo foi verificar a associação entre dependência do exercício físico (DEF) e percepção da qualidade de vida relacionada à saúde (QVRS) em atletas do basquetebol master brasileiro. A amostra foi composta por 410 atletas do sexo masculino. QVRS foi avaliada por meio do Medical Outcomes Study (SF-36). DEF foi avaliada com a Negative Addiction Scale. A Razão de Prevalência (RP) foi usada como medida de associação. Os resultados revelaram a associação negativa da DEF e QVRS, baixos níveis de DEF foram associados a oito domínios da QVRS (RP entre 2,88 e 1,45) e a média DEF a seis domínios da QVRS (RP entre 1,80 e 1,31). Em conclusão, a DEF pode diminuir os níveis de percepção da QVRS dos atletas, tanto em aspectos físicos quanto mentais.

Abstract The current study aimed to investigate the association between physical exercise dependence (PED) and health-related quality of life (HRQoL) perception in Brazilian master basketball athletes. The sample consisted of 410 male athletes. HRQoL was assessed using the Medical Outcomes Study (SF-36). DEF was assessed with the Negative Addiction Scale. Prevalence Ratio (PR) was used as a measure of association. The results exposed a negative association of DEF and HRQOL, and low DEF levels were associated with eight HRQoL domains (PR between 2.88 and 1.45), and the medium DEF with six HRQoL domains (PE between 1.80 and 1.31). In conclusion, DEF can decrease athletes HRQoL perception levels, both physical and mental aspects.

ASSOCIATION BETWEEN WEIGHT-TEASING AND PHYSICAL ACTIVITY IN ADOLESCENTS. / ASSOCIAÇÃO ENTRE A PROVOCAÇÃO REFERENTE AO PESO CORPORAL E A ATIVIDADE FÍSICA EM ADOLESCENTES.

OBJECTIVE: The aim of the study was to determine the association between weight-teasing and physical activity in students from public schools of Curitiba, Paraná (Southern Brazil). METHODS: The sample consisted of 95 students (48 boys and 47 girls) aged 12 to 14 years old. The Perception of Weight Teasing (POTS) and The Perception of Weight Teasing during Physical Activity Scale assessed the frequency of weight-teasing experienced by the participants. Accelerometers measured physical activity. BMI assessed the weight status of the participants. Pearson correlations analyzed the association between the teasing and physical activity variables at a significance level of 0.05. RESULTS: The relationship between teasing variables and physical activity was not significant. A large proportion of participants failed to meet the recommended levels of physical activity regardless of sex (72%), and girls were significantly less physically active than boys (56.3% of boys and 89.4% of girls; p<0.01). CONCLUSIONS: Some participants were targets of weight-teasing, but teasing was not related to physical activity. Interventions are necessary to educate middle school students about the harmful consequences of weight teasing.

Quality of life perception of basketball master athletes: association with physical activity level and sports injuries.

This study aimed to verify the prevalence and characteristics of sports injuries (SI) and determine the association between the physical activity level (PA) and SI with perception of health-related quality of life (HRQoL) in Brazilian basketball master athletes. A cross-sectional study was conducted with 410 male master athletes, between 35 and 85 years of age (mean 52.26, SD ±11.83). The HRQoL was assessed using the Medical Outcomes Study - Short Form-36. The PA was evaluated using the International Physical Activity Questionnaire. Information regarding SI was collected using the Reported Morbidity Survey. Poisson regression, as estimated by the prevalence ratio (PR), was used as a measure of the association of PA and SI with HRQoL. The majority of athletes showed a high SI prevalence (58.3%) and reported one injury (67.8%) that occurred during training (61.1%) and primarily affected a lower limb (74.6%). The adjusted regression models showed a positive association of PA with the Functional Capacity (PR = 1.46, 95% confidence interval [CI] = 1.12-1.90) and Physical Component (PR = 1.32, 95% CI = 1.03-1.70) of HRQoL. Furthermore, the SI were negatively associated with HRQoL in Functional Capacity (PR = 1.85, 95% CI = 1.51-2.27), Physical Aspects (PR = 3.99, 95% CI = 3.08-5.18), Pain (PR = 1.65, 95% CI = 1.26-2.16), Social Functioning (PR = 1.79, 95% CI = 1.41-2.27), Emotional Aspects (PR = 4.40, 95% CI = 3.35-5.78), Mental Health domains (PR = 1.37, 95% CI = 1.06-1.68), Physical Component (PR = 2.35, 95% CI = 1.90-2.90) and Mental Component (PR = 2.65, 95% CI = 2.14-3.29). These results highlighted that master athletes showed a high SI prevalence, primarily in the lower limbs. PA positively correlates with the physical HRQoL domain, whereas SI may decrease the HRQoL levels of both physical and mental domains.

ATIVIDADE FÍSICA E AGREGAÇÃO DE FATORES DE RISCO METABÓLICOS EM ADOLESCENTES / PHYSICAL ACTIVITY AND CLUSTERING OF METABOLIC RISK FACTORS IN ADOLESCENTS

Identificar a associação da atividade física (AF) com a agregação dos fatores de risco metabólicos em adolescentes de Curitiba, Paraná. Participaram do estudo 162 adolescentes (64 meninos). Foram avaliados os níveis de AF (por meio de acelerômetros), o perfil metabólico (glicêmico e lipídico) e antropométrico (circunferência de cintura). Calculou-se Escores Z para cada fator de risco e a soma destes escores categorizou o Escore de Risco Metabólico (ERM). Para análise estatística, utilizou-se da correlação de Spearman e do teste de Kruskal-Wallis adotando p<0,05. Os resultados demonstram quea AF relacionou-se inversamente com os valores de Triglicerídeos (r=-0,217, p<0,05), Colesterol Total (r=-0,243, p<0,05), LDL-C (r=-0,211, p<0,05) e ERM (r=-0,269, p<0,01) nas meninas. Meninas do grupo de maior nível de AF apresentaram menores valores de Colesterol Total e ERM em comparaçãoàs do grupo de baixo nível de AF (p<0,01). Conclui-se que a prática de AF favoreceu o melhor perfil metabólico nas meninas.

The purpose was to identify the association between physical activity (PA) and clustering of metabolic risk factors in adolescents from Curitiba, Parana. As methods, 162 adolescents (64 boys) composed the sample. PA levels (through accelerometers) and metabolic (glucose and lipid) and anthropometric (waist circumference) profiles were assessed. Z scores were calculated for each risk factor and the sum of these scores categorized the Metabolic Risk Score (MRS). For statistical analysis, we used the Spearman rank correlation and the Kruskal-Wallis test, considering p <0.05. The results shows PA was inversely related with Triglycerides (r=-0.217, p<0.05), Total Cholesterol (r=-0.243, p<0.05), LDL-C (r=-0.211, p <0.05) and MRS (r = -0.269, p<0.01) in girls. Girls grouped at highest level of PA had lower values of Total Cholesterol and MRS compared to the low level group of PA (p<0.01). In conclusion the practice of PA favored the better metabolic profile in girls.

Functional fitness in older women from southern brazil: normative scores and comparison with different countries / Aptidão funcional em idosas do sul do brasil: valores normativos e comparação com idosas de diferentes países

Abstract Functional fitness loss during aging may compromise the quality of life and independence of older subjects. It is important to evaluate and diagnose the functional fitness of the elderly population. This study proposed normative functional fitness scores for a sample of elderly women from southern Brazil and compared values to their counterparts in the US, Extremadura (Spain), Taiwan (China) and Spain. The study sample consisted of 1,783 older women aged 60.0 to 84.9 years (mean 68.7 years; standard deviation 6.3 years) who performed the proposed motor tests of the "Senior Fitness Test" for functional fitness in older women. The percentile values specific to each age group were calculated based on the seven functional fitness components: body mass index, 6-minute walk, arm curl, 30-s chair stand, chair sit-and-reach, backscratch, and 8-feet up-and-go. The non-parametric binomial test compared the 50th percentile value of Brazilian older women with those from other countries. Older women´s performance in the functional capacity tests decreased across age groups. The mean BMI varied among age groups from 29.11 to 26.76 kg/m2, 6-minute walk from 572.94 to 486.95 m, arm curl from 17.51 to 15.11 repetitions, 30-schair stand from 15.62 to 14.30 repetitions, chair sit-and-reach from 1.01 to - 0.47 cm, back scratch from -4.92 to -10.52 cm and 8-feet up-and-go from 5.96 to 6.83 sec. Functional fitness scores among older women in different countries differed significantly. However, the direction and magnitude of differences were specific to the functional fitness component. Significant differences were observed in the normative scores, suggesting that the use of international normative scores in Brazilian older women may underestimate or overestimate potential functional limitations.

Resumo A perda da aptidão funcional durante o envelhecimento pode comprometer a independência e qualidade de vida dos idosos. Sua avaliação é uma importante etapa do diagnóstico do estado de saúde dessa população. Objetivou-se propor valores normativos da aptidão funcional em idosas do sul do Brasil e comparar seus valores com idosas dos Estados Unidos, Estremadura (Espanha), Taiwan (China) e Espanha. A amostra do estudo foi composta por 1.783 idosas com idades entre 60,0 e 84,9 anos (média de 68,7 anos; desvio padrão de 6,3 anos), as quais efetuaram os testes motores propostos na "Senior Fitness Test" para a aptidão funcional em idosos. Os valores percentílicos, específicos para cada grupo etário, foram calculados para os sete componentes da aptidão funcional. O teste não paramétrico binomial foi utilizado para comparar o percentil 50 das idosas brasileiras com o das idosas de outras localidades. Foi possível observar que o rendimento das idosas nos testes de capacidade funcional reduziu com o avanço da idade. A média do IMC variou entre os grupos etários de 29,11 a 26,76kg/m2; Andar 6 minutos de 572,94 a 486,95 m, Flexão de antebraço de 17,51 a 15,11repetições, Sentar e levantar de 15,62 a 14,30 repetições, Sentar e Alcançar de 1,01 a -0,47 cm, Alcançar atrás das costas -4,92 a -10,52 cm e Sentado e caminhar de 5,96 a 6,83 seg. Os escores de aptidão funcional apresentaram clara diferença entre os países. Contudo, a direção e a magnitude das diferenças entre idosas de diferentes países variaram de acordo com o indicador de aptidão funcional. Houve importantes distinções entre os valores percentílicos de idosas brasileiras e os de outras localidades, sugerindo que a utilização de valores normativos internacionais pode subestimar ou superestimar limitaçõesfuncionais em idosas brasileiras.

Step-Count Guidelines for Children and Adolescents: A Systematic Review.

BACKGROUND: The aim of this systematic review was to identify the most optimal step-count cutoff for children and adolescents (5-19 years old) among guidelines currently available in the literature. METHODS: The databases searched were PubMed, SportDiscus, Science Direct, Web of Science and LILACS. Studies were categorized into Health Cohort studies or Physical Activity (PA) Cohort studies according to the reference standard used. The quality of the studies was assessed using the QUADAS-2 instrument. RESULTS: Six Health and 3 PA Cohort studies were included in the final pool of papers after Full Text reading. With the exception of a single study, studies demonstrated a high risk of methodological bias in at least 1 of the QUADAS-2 domains. Guidelines ranged from 10,000 to 16,000 steps/day for the Health studies (5-16 years old), and from 9,000 to 14,000 steps/day for PA studies (6-19 years old). Due to the high risk of methodological bias, none of the Health Cohort guidelines were endorsed. The PA Cohort study with the lowest risk of methodological bias suggested 12,000 steps/day for children and adolescents irrespective of gender. CONCLUSION: PA Cohort studies demonstrated lower risk of methodological bias than Health Cohort studies. The optimal youth step-count guideline of 12,000 steps/day was endorsed.

The Association Between Physical Activity and Quality of Life Domains Among Older Women.

This study examined whether the weekly volume and frequency of moderate to vigorous physical activity (MVPA) and light walking (LW) were associated with quality of life (QOL) domains of 1,806 older women from Brazil. The WHOQOL-BREF and WHOQOL-OLD instruments were used to measure QOL, while the weekly volume and frequency of MVPA and LW were assessed by IPAQ. An ordinal logistic regression was used as a measure of association. The weekly volumes of MVPA and LW were associated with several domains of QOL. Higher frequency of MVPA was associated with better scores in 10 QOL domains. The weekly frequency of LW, in turn, was associated with all QOL domains. In conclusion, promoting active transport and encouraging physical activity in older adults, for at least 150 min and distributed several days per week, help to increase QOL.

Atividade física e alimentação associadas aos perfis antropométrico e lipídico em adolescentes / Physical activity and eating habits associated with anthropometricand lipid profiles among adolescents

Objetivo: Verificar a associação dos níveis de atividade física e dos hábitos alimentares com os perfis antropométrico e lipídico em adolescentes de Curitiba, Paraná. Métodos: Coletou-se colesterol total, LDL-c, HDL-c, triglicerídeos, IMC, e verificou-se nível socioeconômico (NSE), atividade física, comportamento sedentário e frequência alimentar de 572 jovens. Para estatísticas descritivas e regressão logística binária, utilizou-se o SPSS 17.0. Resultados: Os meninos foram mais ativos que as meninas e estas apresentaram mais chances de terem níveis de colesterol e LDL-c alterados, respectivamente 67% e 53%. Observou-se associação entre o NSE alto e elevados níveis de triglicerídeos (p<0,05). Os indivíduos classificados no segundo e terceiro quartis da atividade física moderada a vigorosa apresentaram maiores chances de ter HDL-c alterado, comparado ao primeiro quartil. Conclusão: As meninas apresentaram perfil metabólico menos favorável que os meninos, além disso, existe uma associação entre a AFMV e os níveis de HDL-c.

Objectives: To verify the association of physical activity and eating habits with the anthropometric and lipid profiles among adolescents from Curitiba, Paraná. Methods: The variables collected were total cholesterol, LDL-c, HDL-c, triglycerides, BMI, socioeconomic status (SES), physical activity, sedentary behavior and eating frequency. Descriptive statistics and binary logistic regression were realized by SPSS 17.0. Results: Boys were more physically active than girls, and girls had 67% and 53% more chance of having elevated cholesterol and LDL-c, respectively. We observed an association between high SES and elevated triglycerides (p<0.05). Who is classified into the second and third moderate to vigorous physical activity level quartiles is more susceptible of having altered HDL-c comparing to first quartile. Conclusion: Girls had a metabolic profile less favorable than boys, and there is a significantly association between MVPA level and HDL-c.

Association between physical activity and quality of life in the elderly: a systematic review, 2000-2012

Objective: To review information regarding the association of physical activity (PA) with quality of life (QoL) in the elderly and to identify the study designs and measurement instruments most commonly used in its assessment, in the period 2000-2012. Methods: Relevant articles were identified by a search of four electronic databases and cross-reference lists and by contact with the authors of the included manuscripts. Original studies on the association between PA and QoL in individuals aged 60 years or older were examined. The quality of studies as well as the direction and the consistency of the association between PA and QoL were evaluated. Results: A total of 10,019 articles were identified as potentially relevant, but only 42 (0.42%) met the inclusion criteria and were retrieved and examined. Most studies demonstrated a positive association between PA and QoL in the elderly. PA had a consistent association with the following QoL domains: functional capacity; general QoL; autonomy; past, present and future activities; death and dying; intimacy; mental health; vitality; and psychological. Conclusion: PA was positively and consistently associated with some QoL domains among older individuals, supporting the notion that promoting PA in the elderly may have an impact beyond physical health. However, the associations between PA and other QoL domains were moderate to inconsistent and require further investigation. .

Associação entre comportamento sedentário e perfil antropométrico e metabólico entre adolescentes / Asociación entre sedentarismo y los perfiles metabólicos y antropométricos en adolescentes / Association between sedentary behavior and anthropometric and metabolic profiles among adolescents

The purpose of this study was to establish the association between sedentary behavior and the anthropometric and metabolic profiles within a sample group of 572 adolescents from public schools in the city of Curitiba, State of Paraná, Brazil. Approximately 8 ml of blood was drawn to measure total cholesterol (TC), LDL-c, HDL-c, triglycerides, and glucose. Stature and body mass were measured to calculate the body mass index. Information about the subjects' socioeconomic status, physical activity level, sedentary behavior, eating frequency, as well as personal information was obtained through questionnaires. Descriptive statistics, measures of central tendency and percentage score, and Binary Logistic Regression were used to obtain the odds ratio with a CI of 95% and p<0.05. Half of the girls had TC levels classified as borderline or altered, and total screen time presented a significant association between the metabolic variables analyzed in the study. We conclude that girls had TC levels less favorable than that of the boys and that screen time is associated with some metabolic variables.

O objetivo deste estudo foi verificar a associação entre o comportamento sedentário e o perfil antropométrico e metabólico em uma amostra de adolescentes de Curitiba, Paraná. Participaram da pesquisa 572 adolescentes da rede pública de ensino. Coletou-se aproximadamente 8 ml de sangue para determinar o colesterol total (CT), lipoproteína de baixa densidade, lipoproteína de alta densidade, triglicerídeos e glicemia. Mensurou-se a estatura e massa corporal para cálculo do índice de massa corporal. Obteve-se dados sobre informações pessoais, nível socioeconômico, nível de atividade física, comportamento sedentário e frequência alimentar através de questionários auto preenchidos. Utilizou-se estatística descritiva, medidas de tendência central e proporção, e a Regressão Logística Binária para obtenção do razão de chances com intervalo de confiança de 95% e p<0,05. Metade das moças apresentou alterações no CT e houve uma associação positiva significativa entre o tempo total de tela e as variáveis metabólicas avaliadas no estudo. Conclui-se que as meninas mostraram valores de CT menos favorável que os rapazes e, existe uma correlação entre o tempo de tela e algumas variáveis metabólicas.
