Práctica de actividad física por medio de videojuegos activos en el abordaje de la obesidad en edades pediátricas

El incremento de la obesidad en el mundo demanda de un plan estratégico dirigido a su prevención en el inmediato, mediano y a largo plazo, dado que los niños que desde edades tempranas presentan condiciones de obesidad, tienden a mantener este estado en periodos siguientes de su vida, lo que conlleva a adquirir otras enfermedades denominadas no transmisibles. Estudios adelantados han identificado estrategias fundamentadas en el desarrollo de propuestas tecnológicas que aportan a la promoción de la actividad física mediante juegos activos para los niños. Estas propuestas constituyen alternativas postmodernas que motivan a un cambio de conductas sedentarias para la consolidación de hábitos de vida saludables. Es necesario la implementación de programas orientados a la prevención de la obesidad en edades pediátricas, mediados por videojuegos activos como alternativas didácticas que promuevan la disminución de los periodos de sedentarismo y el control de enfermedades crónicas no transmisibles.

The increase in obesity in the world demands a strategic plan aimed at its prevention in the immediate, medium and long term, given that children who present with obesity from an early age tend to maintain this state in subsequent periods of their lives, which leads to acquiring other so-called non-communicable diseases. Advanced studies have identified strategies based on the development of technological proposals that contribute to the promotion of physical activity through active games for children. These proposals constitute postmodern alternatives that motivate a change in sedentary behaviors to consolidate healthy lifestyle habits. It is necessary to implement programs aimed at preventing obesity in pediatric ages, mediated by active video games as educational alternatives that promote the reduction of periods of sedentary lifestyle and the control of chronic non-communicable diseases.

Association between sedentary behavior, diet and nutritional status in adolescents: baseline results from the LONCAAFS Study / Associação entre comportamento sedentário, dieta e estado nutricional em adolescentes: resultados do estudo LONCAAFS

Abstract The aim of the present study was to analyze the relationship between time spent engaged in sedentary behaviors, type of diet, and overweight in adolescents. A cross-sectional study using data from the Longitudinal Study on Sedentary Behavior, Physical Activity, Eating Habits, and Health of Adolescents - LONCAAFS Study. A total of 1,438 adolescents (10 to 14 years old) from public schools in the city of João Pessoa, Brazil, participated in the study. To evaluate the combined effects of excessive time in sedentary behavior and consumption from two food groups: Convenience and Prudent on overweight, we performed multiple logistic regression analyses, adjusted for energy, level of physical activity, sex, and age. Excessive time in sedentary behavior increased the chance of adolescents being overweight by 37% (OR = 1.37; 95%CI: 1.04-1.80). This chance increased to 43% when the adolescents were simultaneously engaged in excessive sedentary behavior and had high consumption of the Convenience food group (OR = 1.43; 95%CI: 1.05-1.94) and increased to 39% on those who engaged in excessive sedentary behavior and had low consumption of foods from the Prudent (OR = 1.39; 95%CI: 1.04-1.84). Excessive sedentary behavior is associated with being overweight and the chance increases with the consumption of convenient foods.

Resumo O objetivo do estudo foi analisar a relação entre tempo gasto em comportamentos sedentários, dieta e excesso de peso em adolescentes. Estudo transversal com dados do Estudo Longitudinal sobre Comportamento Sedentário, Atividade Física, Hábitos Alimentares e Saúde do Adolescente - Estudo LONCAAFS. Participaram 1.438 adolescentes (10 a 14 anos) de escolas públicas de João Pessoa, Brasil. Para avaliar os efeitos combinados do tempo excessivo no comportamento sedentário e no consumo de dois grupos de alimentos: Conveniência e Prudente sobre o excesso de peso, foram realizadas análises de regressão logística múltipla, ajustadas para energia, nível de atividade física, sexo e idade. O tempo excessivo em comportamento sedentário aumentou em 37% a chance de os adolescentes apresentarem excesso de peso (OR = 1,37; IC95%: 1,04-1,80). Essa chance aumentou para 43% quando os adolescentes apresentaram, simultaneamente, comportamento sedentário excessivo e alto consumo do grupo de alimentos de conveniência (OR = 1,43; IC95%: 1,05-1,94), e aumentou para 39% naqueles com excesso de comportamento sedentário e baixo consumo de alimentos do Prudente (OR = 1,39; IC95%: 1,04-1,84). O comportamento sedentário excessivo está associado ao excesso de peso e a chance aumenta com o consumo de alimentos convenientes.

Leisure-time physical activity as a key protective factor against cognitive decline in older adults: an isotemporal substitution analysis / Atividade física de lazer como fator-chave de proteção contra o declínio cognitivo em idosos: uma análise de substituição isotemporal / La actividad física en el tiempo libre como factor protector clave contra el deterioro cognitivo en adultos mayores: un análisis de sustitución isotemporal

Abstract: This study aimed to test hypothesized effects of replacing sedentary behavior with moderate-to-vigorous physical activity, sleep, and different domains of physical activity by equivalent amounts on suggestive cognitive decline in an older adult population. This was a cross-sectional study including 473 older adults aged ≥ 60 years. Cognitive decline was assessed using the Mini-Mental Health Examination. Physical activity, its different domains and the time of exposure to sedentary behavior were assessed using the International Physical Activity Questionnaire. For data analysis, two isotemporal substitution models were constructed using Poisson regression. The first model tested the effect of sleep time, sedentary behavior, and moderate-to-vigorous physical activity on cognitive decline. The second model was used to determine the effect of physical activity domains (leisure, work, transport, and home), sleep time, and sedentary behavior on cognitive decline. Physical activity during leisure time was protective against cognitive decline among all domains tested, replacing sedentary behavior, sleep, and transport. Conversely, substitution of the leisure domain for sedentary behavior, sleep, and transport was considered a risk factor for cognitive decline. Leisure time proved to be a strong protective factor in reducing the risk of cognitive decline, and it is necessary to encourage and stimulate public policies that include it.

Resumo: Este estudo objetivou verificar os efeitos hipotéticos da substituição do comportamento sedentário por atividade física moderada a vigorosa, sono e diferentes domínios da atividade física por quantidades equivalentes sobre o declínio cognitivo em uma população idosa. Trata-se de um estudo transversal, com 473 idosos de ≥ 60 anos. O declínio cognitivo foi avaliado por meio do Mini Exame do Estado Mental. A atividade física, seus diferentes domínios e o tempo de exposição ao comportamento sedentário foram avaliados por meio do Questionário Internacional de Atividade Física. Para a análise dos dados, foram utilizados dois modelos de substituição isotemporal, por meio da regressão de Poisson. O primeiro modelo testou o efeito do tempo de sono, comportamento sedentário e atividade física moderada a vigorosa no declínio cognitivo. O segundo modelo foi utilizado para determinar o efeito dos domínios de atividade física (lazer, trabalho, transporte e casa), tempo de sono e comportamento sedentário no declínio cognitivo. A atividade física no lazer foi um fator protetivo contra declínio cognitivo em todos os domínios testados, substituindo comportamento sedentário, sono e transporte. Por outro lado, a substituição do domínio lazer por comportamento sedentário, sono e transporte foi considerada fator de risco para o declínio cognitivo. O tempo livre mostrou-se um forte fator protetor na redução do risco de declínio cognitivo, sendo necessário incentivar e estimular políticas públicas.

Resumen: Este estudio tuvo como objetivo verificar los efectos hipotéticos al reemplazar el comportamiento sedentario por actividad física de moderada a vigorosa, sueño y diferentes dominios de actividad física por cantidades equivalentes sobre el deterioro cognitivo en una población anciana. Se trata de un estudio transversal, con 473 ancianos ≥ 60 años. El deterioro cognitivo se evaluó mediante el Mini Examen del Estado Mental. La actividad física, sus diferentes dominios y el tiempo de exposición al comportamiento sedentario se evaluaron mediante el Cuestionario Internacional de Actividad Física. Para el análisis de los datos, se utilizaron dos modelos de reemplazo isotemporal, utilizando la regresión de Poisson. El primer modelo probó el efecto del tiempo de sueño, comportamiento sedentario y actividad física de moderada a vigorosa en el deterioro cognitivo. El segundo modelo se utilizó para determinar el efecto de los dominios de actividad física (ocio, trabajo, transporte y hogar), tiempo de sueño y comportamiento sedentario en el deterioro cognitivo. La actividad física en el tiempo libre fue un factor protector contra el deterioro cognitivo en todos los dominios evaluados, reemplazando el comportamiento sedentario, el sueño y el transporte. Por otra parte, reemplazar el dominio del ocio por comportamiento sedentario, sueño y transporte se consideró un factor de riesgo para el deterioro cognitivo. El tiempo libre demostró ser un fuerte factor protector para reducir el riesgo de deterioro cognitivo, por lo que es necesario fomentar y estimular políticas públicas.

Relación de las Enfermedades Crónicas no Transmisibles y Ejercicio Físico en la Población Chilena entre los años 2015-2016 / Risk of Retention of Secretions in Patients with Invasive Mechanical Ventilation

Introducción. Las prevalencias de la inactividad física, el sedentarismo y el sobrepeso y obesidad han aumentado sus índices durante los últimos años en Chile, lo que conlleva al desarrollo y aparición de diversas enfermedades crónicas no transmisibles, como por ejemplo, hipertensión arterial, diabetes mellitus e inclusive enfermedades respiratorias, las cuales repercuten negativamente en la población y deterioran la calidad de vida de las personas, independientemente el sexo y el rango etario. El ejercicio físico es una de las principales herramientas utilizadas por diversos profesionales de la salud como método de prevención y tratamiento en la población afectada, inclusive representa una alternativa de menor costo. Objetivo. Relacionar el ejercicio físico de alta y mediana intensidad con las enfermedades crónicas no transmisibles en personas mayores a 18 años residentes en Chile durante el periodo 2015-2016. Métodos. Análisis cuantitativo, descriptivo, transversal y retrospectivo de base secundaria ENCAVI 2015-2016, de residentes en Chile mayores de 18 años y con al menos una de las siguientes condiciones de salud: Hipertensión arterial, Diabetes Mellitus y enfermedades respiratorias crónicas no transmisibles. Resultados. Todas las variables presentan relaciones significativas (p<0,005) (HTA, DM, enfermedades respiratorias, edad, horas sentado, ejercicio físico de moderada y alta intensidad. Sin embargo, las variables de ejercicio físico moderada intensidad y enfermedades respiratorias (p=0,578) y las variables de sexo y horas sentado (p=0,005) no presentan relación significativa. Discusión. El ejercicio físico de moderada intensidad es el que tiene mejor respuesta ante las diferentes patologías según diferentes autores, por otro lado, en la recopilación de datos podemos encontrar que este tipo de ejercicio es efectivo en la Diabetes Mellitus. Conclusiones. Según los datos analizados, mientras mayor frecuencia de ejercicio físico de alta intensidad (en días) y ejercicio físico de moderada intensidad (en horas) se realice durante los últimos días de la semana, los diagnósticos de las enfermedades crónicas no transmisibles (HTA, DM) y enfermedades respiratorias se verán controladas, mientras que, cuando existe menor frecuencia del ejercicio físico realizado durante los últimos días de la semana, tiende a existir mayor diagnóstico.

Background. The prevalence of physical inactivity, sedentary lifestyle, and overweight and obesity have increased their rates in recent years in Chile, which leads to the development and appearance of various chronic non-communicable diseases, such as for example, arterial hypertension, diabetes mellitus and even respiratory diseases, which have a negative impact on the population and deteriorate the quality of life of people, regardless of gender and age range (7). Physical exercise is one of the main tools used by various health professionals as a method of prevention and treatment in the affected population, even representing a lower cost alternative. Objetive. To relate high and medium intensity physical exercise with chronic non-communicable diseases in people over 18 years of age residing in Chile during the period 2015-2016. Methods. Quantitative, descriptive, cross-sectional and retrospective analysis of the ENCAVI 2015-2016 secondary base of residents in Chile over 18 years of age and with at least one of the following health conditions: High blood pressure, Diabetes Mellitus and chronic non-communicable respiratory diseases. Results. All the variables present significant relationships (p<0.005) (HTN, DM, respiratory diseases, age, hours sitting, moderate and high intensity physical exercise. However, the variables of moderate intensity physical exercise and respiratory diseases (p=0.578) and the variables of sex and sitting hours (p=0.005) do not present a significant relationship. Discussion. Moderate intensity physical exercise is the one that has the best response to different pathologies according to different authors, on the other hand, in data collection we can found that this type of exercise is effective in Diabetes Mellitus. Conclusions. According to the data analyzed, the greater the frequency of high-intensity physical exercise (in days) and moderate-intensity physical exercise (in hours) performed during the last days of the week, the diagnoses of chronic non-communicable diseases (HTN, DM) and respiratory diseases will be controlled, while, when there is less frequency of physical exercise carried out during the last days of the week, there tends to be a greater diagnosis.

Effect of sedentary interval intervention on body composition and blood lipid metabolism of obese female college students / 中国学校卫生

Objective@#To explore the intervention effect of sedentary interval on body composition and blood lipid metabolism of obese female college students, so as to provide reference for health promotion among obese students.@*Methods@#Eighty obese female college students from first and second grades were randomly assigned into three groups, the control group ( n =28), experimental group A ( n =26), and experimental group B ( n =26), between September and November 2022. The participants received appropriate dietary guidance, a 90-minute optional physical education course was offered to control group once a week, on the basis of the control group, experimental group A performed 5-minute-intermittent brisk walking (6 km/h) during each break. Experimental group B performed 5-minute-intermittent brisk walking (6 km/h) during each break for the first 4 weeks, then changed to 4-minute-brisk walking (6 km/h) and 1-minute-rope skipping (60 skips/min) during each break for weeks 5-8, and changed to 4-minute-brisk walking (6 km/h) and 1-minute-rope skipping (80 skips/min) during each break for 9-12 weeks. The intervention was performed 10 times per day, with the interruption time and frequency on weekends remaining the same. Body mass index (BMI), body fat rate (BFR), waist hip ratio (WHR), visceral fat index (VFI), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were measured before and after the experiment.@*Results@#After 12 weeks intervention, there were no significant differences in body composition and blood lipids in control group ( P >0.05), BMI, BFR, VFI and TG in Group A were lower than those before intervention ( t=3.20, 2.80, 8.19, 2.21, P <0.05), BMI, BFR, WHR, VFI, TG, TC, LDL-C were lower and HDL-C in group B were higher than those before intervention ( t=6.27, 5.85, 10.82 , 19.91, 3.86, 3.29, 7.20, -4.93, P <0.01). There were significant differences in BMI, BFR, WHR, VFI and HDL-C among the three groups ( F=24.01, 23.77, 10.00, 15.28, 6.72, P <0.01), and the intervention effects of BMI, BFR and HDL-C in group B were better than those in group A and control group ( P <0.01).@*Conclusion@#The intervention of brisk walking and rope skipping had a good effect on improving body composition and blood lipid metabolism of obese female college students. Schools should make good use of the time between classes and adopt short-time and high-intensity exercise intervention to improve the body composition and blood lipid metabolism of obese students.

@#Introduction: Metabolic syndrome has become a worry for health of youth in Malaysia. This study aimed to look at the prevalence of metabolic syndrome, and to assess the risk factors of metabolic syndrome among Malaysian university students. Methods: A cross-sectional study was conducted on 248 students aged 18-30 years using a random sampling method from two universities in Bintulu, Sarawak, Malaysia. Data on sociodemographic, dietary habits and lifestyle were collected by a pre-tested self-reported questionnaire. Biochemical measurements, blood pressure, and anthropometric measurements were measured by standard procedures. Metabolic syndrome was defined according to Harmonized Joint Interim Statement criteria. Data were analysed using IBM SPSS 23.0 version. Results: The overall prevalence of metabolic syndrome was 12.5% and was more prevalent in male (17.5%). Indian (15.8%) was the most prevalent ethnic group, while Chinese (4.9%) had the least prevalence. 31.5% respondents had at least one metabolic component. Low HDL (42.7%) and large waist circumference (26.2%) were the most common components. Statistically significant (p<0.05) independent factors for developing metabolic syndrome were male, staying time more than six hours on computer/TV/mobile phone, in smokers, taking meals more than three times per day, and high consumption of soft drinks. Besides that, with high consumption of vegetables, the prevalence of metabolic syndrome was significantly low (p<0.05). Conclusion: These study findings elicit the evidence of increasing tendency and warning on metabolic syndrome for Malaysian university students, and considerable association of the prevalence of metabolic syndrome to dietary habits and lifestyle.

Association of light-intensity physical activity, sedentary time and body composition in adolescents / 中国学校卫生

Objective@#To explore the association between light intensity physical activity (LPA) and sedentary behavior (SB) with body composition, so as to provide data references for improving adolescent physical health.@*Methods@#From August 2020 to January 2021, general information of 694 students in grade one of a high school in Foshan City was collected, and the 24 hour activity behavior and body composition of the students were measured objectively by triaxial accelerometer and bioelectrical impedance tester. Dual component multivariate regression and dual compositional isotemporal substitution model were used to explore the relationship between LPA and SB and body composition.@*Results@#LPA was associated with lower fat relative dominance (FRD) (male weekends FRD=-21.44%, female weekly FRD=-17.83%, weekdays FRD=-18.27%, P <0.05), and LPA was also associated with higher muscle relative dominance (MRD) and bone relative dominance (BRD) (male weekends MRD=12.78%, BRD= 12.87 %; female weekly MRD=11.64%, BRD=9.01%; female weekdays MRD=12.02%, BRD=9.23%, P <0.05). Replacing sedentary behavior (SB) with 10 minutes of LPA could reduce fat proportion [male:weekly -0.15(-0.26--0.04), weekdays -0.12 (-0.22--0.02); female:weekly -0.18(-0.27--0.08), weekdays -0.16(-0.25--0.07)) and increase muscle proportion (male:weekly 0.14(0.03-0.24), weekdays 0.11(0.02-0.21); female:weekly 0.17(0.07-0.26), weekdays 0.15(0.07-0.24)].@*Conclusion@#Interrupting continuous SB with LPA can serve as an intervention measure to promote physical health and fitness in adolescents. School should encourage students to engage in frequent LPA during breaks and after school activities, while avoiding prolonged SB.

Cluster characteristics of physical activities among children inside and outside kindergartens and its relationship with athletic abilities / 中国学校卫生

Objective@#Based on physical activity (PA) and sedentary behavior (SB) variables on weekdays and weekends, the study aims to cluster the physical activities inside and outside kindergartens and to explore the cluster characteristics of different children using physical fitness indicators, so as to provide new strategies and methods for early childhood education and health.@*Methods@#From March to June 2019, 291 children aged 3-6 years from 6 kindergartens in Nanchang were recruited by a stratified cluster random sampling method. The ActiGraph GT3X-BT triaxial accelerometer was used to measure and analyze the PA and SB levels inside and outside the kindergarten. A twostep clustering algorithm model was employed for cluster analysis. Physical fitness were measured and evaluated according to the "National Physical Fitness Measurement Standard Manual (Preschool Section)". Differences in physical fitness among different clusters of children were compared, and the cluster characteristics of different children were analyzed.@*Results@#The clustering algorithm model indicated that based on six indicators, including PA and SB inside the kindergarten on weekdays, and PA and SB outside the kindergarten on both weekdays and weekends, children could be divided into three categories:active inside (high PA, low SB inside), active outside (high PA outside), and inactive (low PA, high SB both inside and outside). The average silhouette coefficient of the model was 0.3, indicating good clustering results. Both the active inside and active outside children showed significantly higher PA inside on weekdays, PA outside on weekdays and weekends, daily low intensity physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) than the inactive children ( F=157.91, 80.79 , 95.86, 95.52, 124.74, P <0.05). After adjusting for gender and age, the physical fitness scores of both active outside ( 19.03 ±0.47) and active inside (19.11±0.40) were significantly higher than those of the inactive children (17.94±0.31). Additionally, active inside children (3.91±0.14) also showed significantly better performance in continuous double-leg jumps, compared to inactive children (3.45±0.11) ( P <0.05).@*Conclusion@#Children active inside and those active outside perform well in PA. Future research should focus on the proportion of structured and unstructured PA time to enhance the overall physical fitness of children.

Time trends and COVID-19 post-pandemic changes in physical activity and sedentary behavior prevalence among Brazilian adults between 2006 and 2021 / Tendências temporais e mudanças pós-pandemia de COVID-19 na prevalência de atividade física e comportamento sedentário em adultos brasileiros entre 2006 e 2021

ABSTRACT Objective: To analyze time trends and prevalence of physical activity and sedentary behavior among adults of Brazilian capitals between 2006 and 2021, including the pandemic period. Methods: This is a time-series of cross-sectional surveys based on the National Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey. Trends of sufficient leisure-time physical activity, sufficient physical activity while commuting, insufficient practice of physical activity, and total screen time were estimated by using Prais-Winsten regression. Annual prevalences and time trends were estimated for each indicator by sex, age group and education. Results: For total population, significant time trends were found for leisure-time physical activity (β=0.614) and total screen time (β=1.319). As for prevalence, leisure-time physical activity increased from 29% in 2009 to 39% in 2019, followed by a reduction of 2.3% between 2020 and 2021. Total screen time prevalence increased considerably between 2019 and 2020 (4.7%). Though physical inactivity tended to reduce along the series, its prevalence increased by 3.4% between 2019 and 2021, as well as physical activity while commuting decreased by 3,7% in the same time period. Conclusion: Whereas leisure-time physical activity increased over the years, it is uncertain whether this trend will be the same in the years following COVID-19. Not only did people alter their leisure-time habits, but also there was an increasing dominance of screen time due to the change in work and social patterns. More strategies need to be addressed to tackle physical inactivity and sedentary behavior, and to review the post-pandemic national targets.

RESUMO Objetivo: Analisar as tendências temporais e a prevalência dos indicadores de atividade física e comportamento sedentário em adultos das capitais brasileiras entre 2006 e 2021, incluindo o período de pandemia. Métodos: Trata-se de estudo de série temporal de inquéritos transversais baseado no Sistema de Vigilância Telefônica de Doenças Crônicas. As tendências de atividade física suficiente no lazer, atividade física suficiente no deslocamento, prática insuficiente de atividade física e tempo total de tela foram estimadas por meio da regressão de Prais-Winsten. As tendências temporais e as prevalências anuais foram calculadas por sexo, faixa etária e escolaridade. Resultados: Na população total, foram encontradas tendências temporais significativas para atividade física suficiente no lazer (β=0,614) e tempo total de tela (β=1,319). Quanto à prevalência, a atividade física suficiente no lazer aumentou de 29% em 2009 para 39% em 2019, seguida de redução de 2,3% entre 2020 e 2021. A prevalência do tempo total de tela aumentou consideravelmente entre 2019 e 2020 (4,7%). Embora a inatividade física tendesse a diminuir ao longo da série, sua prevalência aumentou 3,4% entre 2019 e 2021, assim como a atividade física no deslocamento diminuiu 3,7% no mesmo período. Conclusão: Enquanto a atividade física suficiente no lazer aumentou ao longo dos anos, é incerto se essa tendência se manterá nos anos seguintes à COVID-19. Não apenas as pessoas alteraram seus hábitos de lazer, mas também há um domínio crescente do tempo de tela em razão da mudança nos padrões sociais e de trabalho. Mais estratégias precisam ser abordadas para o enfrentamento da inatividade física, do comportamento sedentário e para a revisão das metas nacionais pós-pandemia.

Autopercepção alimentar, imagem corporal e nível de atividade física de universitários que migram para estudar em outra cidade / Food self-perception, body image and physical activity level of university students migrating to study in another city / Autopercepción alimentaria, imagen corporal y nivel de actividad física de estudiantes universitarios que emigran para estudiar en otra ciudad

Objetivo: Avaliar a autopercepção das alterações alimentares, imagem corporal e nível de atividade física de estudantes que migraram para estudar em outra cidade. Métodos: Perfrmou-se um estudo transversal com 28 universitários que responderam 25 questões de um formulário online sobre as alterações alimentares, imagem corporal e nível de atividade física decorrentes da mudança de residência. Resultados: Para o fator quantidade alimentar verificou-se relatos de mudar boa parte ou quase tudo, contudo a qualidade das alterações foram ambíguas como mudar para pior e para melhor, bem como aumetar e diminuir a quantidade de comida por refeição. Estudantes reduziram o número de refeições por dia para 3 a 4, e informaram consumir fast food de 2 a 4x/mês. Avaliados exibiram alto índice de insatifação corporal por sobrepeso, serem fisicamente ativos e elevado tempo sentado. Não observou-se diferença estatística entre os sexos nos parâmetros estudados, todavia, o percentual de homens que diminiuram o número de refeições, insatisfeitos por sobrepeso e ativos fisicamente foi maior. Conclusão: Residir em outra cidade para estudar pode alterar os padrões alimentares de universitários, como também estar assodiada à insatisfação corporal e a comportamentos sedentários apesar de serem fisicamente ativos. Baixo consumo de fast food foi justificado à predominância dos estudantes ter formação acadêmica na área de saúde.

Objective: To evaluate the self-perception of dietary changes, body image and physical activity level of students who migrated to study in another city. Methods: A cross-sectional study was carried out with 28 university students who answered 25 questions on an online form about dietary changes, body image and physical activity level resulting from the change of residence. Results: For the food quantity factor, there were reports of changing most or almost everything, however the quality of the changes were ambiguous, such as changing for worse and for better, as well as increasing and decreasing the amount of food per meal. Students reduced the number of meals per day to 3 to 4, and reported consuming fast food 2 to 4 times/month. Evaluators exhibited a high rate of body dissatisfaction due to being overweight, being physically active and sitting for a long time. There was no statistical difference between genders in the studied parameters, however, the percentage of men who reduced the number of meals, dissatisfied with being overweight and physically active was higher. Conclusion: Living in another city to study can change the eating patterns of university students, as well as being associated with body dissatisfaction and sedentary behavior despite being physically active. Low consumption of fast food was justified by the predominance of students with academic training in the health area.

Objetivo: Evaluar la autopercepción de cambios alimentarios, la imagen corporal y el nivel de actividad física de estudiantes que emigraron para estudiar en otra ciudad. Método: Se realizó un estudio transversal con 28 estudiantes universitarios que respondieron 25 preguntas en un formulario online sobre cambios dietéticos, imagen corporal y nivel de actividad física derivados del cambio de residencia. Resultados: Para el factor cantidad de alimentos, hubo informes de cambiar casi todo o casi todo, sin embargo la calidad de los cambios fue ambigua, como cambiar para peor y para mejor, así como aumentar y disminuir la cantidad de alimentos por comida. Los estudiantes redujeron el número de comidas al día a 3 ó 4, e informaron de que consumían comida rápida entre 2 y 4 veces al mes. Los evaluadores mostraron un alto índice de insatisfacción corporal debido al sobrepeso, a la falta de actividad física y a permanecer mucho tiempo sentados. No hubo diferencias estadísticas entre géneros en los parámetros estudiados, sin embargo, fue mayor el porcentaje de hombres que redujeron el número de comidas, insatisfechos con el sobrepeso y físicamente activos. Conclusiones: Vivir en otra ciudad para estudiar puede cambiar los patrones alimentarios de los universitarios, además de estar asociado a la insatisfacción corporal y al sedentarismo a pesar de ser físicamente activos. El bajo consumo de comida rápida se justificó por el predominio de estudiantes con formación académica en el área de la salud.

Prevalência de problemas vocais entre professores da educação básica e sua relação com o nível de atividade física / Prevalence of vocal problems among teachers of primary education and its relationship with the level of physical activity

Resumo Introdução A atividade física é benéfica para a manutenção da saúde, qualidade de vida, bem-estar físico e psicológico. No entanto, ainda são poucos os estudos que abordam a prática de atividade física e os problemas vocais. Objetivo Verificar a prevalência de problemas vocais e sua associação com o nível de atividade física em professores de escolas públicas da educação básica. Método Estudo transversal analítico com amostra probabilística por conglomerado em estágio único composta de 634 professores. A variável dependente referiu-se à existência de problemas vocais (quatro ou mais sinais/sintomas). As variáveis independentes foram relacionadas aos aspectos sociodemográficos, ocupacionais, hábitos de vida e saúde, consideradas na modelagem como fatores de ajuste. O nível de atividade física foi mensurado pelo International Physical Activity Questionnaire - IPAQ (versão curta). Procedeu-se à análise descritiva, bivariada e múltipla (Regressão de Poisson). Resultados Houve alta prevalência de sinais/sintomas vocais (79,2%), bem como daqueles com quatro ou mais sinais/sintomas, denominados de problemas vocais (27,3%). No modelo final ajustado, a prevalência de problemas vocais foi maior entre professores do sexo feminino (RP=1,9), com maior tempo de docência (RP=1,3), com qualidade de vida insatisfatória no domínio físico (RP=1,9) e no domínio psicológico (1,4) e entre os professores sedentários/insuficientemente ativos (RP=1,3). Conclusão A prática de atividade física mostrou relação com a saúde vocal mesmo após controle por outras variáveis, o que enfatiza a necessidade de conscientização e estímulo aos professores quanto à prática de atividade física.

Abstract Background Physical activity is beneficial for maintaining health, quality of life, physical and psychological well-being. However, there are still few studies that have the practice of physical activity and vocal problems. Objective To identify the prevalence of vocal problems and their association with the level of physical activity in public elementary school teachers. Method A cross-sectional analytical study with a probabilistic sample of a single-stage conglomerate composed of 634 teachers was carried out. The dependent variable was the existence of vocal issues (four or more signs/symptoms). The independent variables were related to sociodemographic, occupational, and life and health aspects, and they were considered in the modeling as adjustment factors. The level of physical activity was measured by the International Physical Activity Questionnaire - IPAQ (short version). Descriptive, bivariate, and multiple analyzes were performed (Poisson Regression). Results There was a high prevalence of vocal signs/symptoms (79.2%), as well as those with four or more signs/symptoms, called vocal problems (27.3%). In the adjusted final model, the prevalence of vocal problems was higher among female teachers (PR = 1.9), with a longer teaching period (PR = 1.3), with poor quality of life in the physical domain (PR = 1.9) and in the psychological domain (1.4), and among sedentary/insufficiently active teachers (PR = 1.3). Conclusion The practice of physical activity showed a relationship with vocal health even after controlling the other variables, which emphasizes the need for teacher awareness and encouragement regarding the practice of physical activity.

Association of physical activity combined with sedentary behavior with dynapenia in older adults / Associação da atividade física combinada ao comportamento sendentário com a dinapenia em idosos

ABSTRACT This research aimed to analyze the association of physical activity (PA) level combined with exposure to sedentary behavior (SB) with dynapenia in older people. Epidemiological, cross-sectional study, conducted with 208 older adults in Aiquara, Bahia, Brazil. Habitual PA and SB were quantified using the International Physical Activity Questionnaire. Based on this information, participants were divided into groups (G): G1) sufficiently active and low SB; G2) sufficiently active and high SB; G3) insufficiently active and low SB; and G4) insufficiently active and high SB. Assessment of dynapenia was performed based on the values of the handgrip strength measured in kilogram-force (kgf) (women: 18.37 kgf; men: 26.75 kgf). Descriptive analysis was conducted using absolute and relative frequencies, mean and standard deviation. For the inferential analysis, Poisson regression was used, with a robust estimator, calculation of Prevalence Ratios (PRs) and their relevant Confidence Intervals (CIs) of 95.0%. It was observed that the mean age of women and men were, respectively, 71.0 ± 6.7 and 72.3 ± 8.1 years and the prevalence of dynapenia observed was about 24.5%. Furthermore, it was found that the insufficiently active older adults with low SB (G3) (PR: 2.28; 95%CI: 1.09-4.76), and those insufficiently active with high SB (G4) (PR: 4, 14; 95%CI: 1.95-8.70), were more likely to experience the assessed outcome. Evidence showed that, among the older adults in Aiquara the prevalence of dynapenia was high in the presence of an insufficient level of PA, especially when combined with greater exposure to SB

RESUMO Esta pesquisa teve como objetivo analisar a associação do nível de atividade física (AF) combinado à exposição ao comportamento sedentário (CS) com a dinapenia em idosos. Estudo epidemiológico, transversal, conduzido com 208 idosos de Aiquara, Bahia, Brasil. A AF habitual e o CS foram quantificados pelo International Physical Activity Questionnaire. A partir destas informações, dividiu-se os participantes em grupos (G): G1) suficientemente ativos e baixo CS; G2) suficientemente ativos e elevado CS; G3) insuficientemente ativos e baixo CS; e G4) insuficientemente ativos e elevado CS. A avaliação da dinapenia foi realizada a partir dos valores, em quilograma-força (kgf), da força de preensão manual (mulheres: 18,37 kgf; homens: 26,75 kgf). A análise descritiva foi conduzida por meio de frequências absolutas e relativas, média e desvio padrão. Para a análise inferencial utilizou-se a regressão de Poisson, com estimador robusto, cálculo das Razões de Prevalência (RP) e de seus respectivos Intervalos de Confiança (IC) de 95,0%. Observou-se que as médias de idade das mulheres e dos homens, foram, respectivamente, 71,0 ± 6,7 e 72,3 ± 8,1 anos e a prevalência de dinapenia observada foi na ordem de 24,5%. Ademais, averiguou-se que os idosos insuficientemente ativos com baixo CS (G3) (RP: 2,28; IC95%: 1,09-4,76), e os insuficientemente ativos com elevado CS (G4) (RP: 4,14; IC95%: 1,95-8,70), apresentaram maior probabilidade ao desfecho analisado. As evidências verificadas mostraram que, entre os idosos de Aiquara, a prevalência de dinapenia foi elevada na presença do nível de AF insuficiente, especialmente quando combinado a uma maior exposição ao CS.

Motivación hacia la práctica de actividades físicas en asistentes del centro gerontológico las Piñas del Cantón Milagro / Motivação para a prática de atividades físicas nos participantes do centro gerontológico Las Piñas, no cantão de Milagro / Motivation towards the practice of physical activities in assistants of the gerontological center "Las Piñas" of the Milagro Canton

RESUMEN Introducción: La motivación le permite al individuo mantenerse en una acción determinada, posibilita la efectividad de procesos pertinentes para el logro de un objetivo específico o general, que para el caso de la actividad física se relaciona con su sistematicidad, y por ende, la mantención de un mejor estilo de vida. Objetivo: La investigación se centró en diagnosticar la motivación hacia la práctica de actividades físicas en Asistentes del Centro Gerontológico Las Piñas Del Cantón Milagro. Materiales y métodos: la metodología utilizada responde a una investigación descriptiva-explicativa, de orden cualitativo. Con un tipo de muestreo no probabilístico, se estudia a 60 adultos mayores como población participante clasificados en géneros. Se trabajó con un instrumento de investigación adaptado, se aplica al test de Rossemberg como base, y una encuesta válida para la medición de las dos variables. Resultados: Los resultados de la investigación determinaron que existe un alto porcentaje de los adultos que se encuentran sedentarios, en relación al género se encontró que las mujeres tienen mayor índice de inactividad que los hombres, sin diferencias significativas (p=0.982). Otra respuesta encontrada es que muchos adultos mayores encuentran como limitantes de la actividad física la percepción de no poder ir al ritmo de los demás, las enfermedades, el miedo a las lesiones, entre otras, siendo variables de consideración en el diseño prospectivo de una estrategia lúdica para mejorar la calidad de vida de las muestras objeto de estudio. Conclusiones: Como parte de las conclusiones se sugieren que se realicen modificaciones en el estilo de vida que llevan los adultos mayores estudiados, lo principal es la motivación que se les puede inculcar desde el hogar y desde las familias.

SÍNTESE Introdução: a motivação permite ao indivíduo permanecer em uma determinada ação, torna possível a eficácia dos processos pertinentes para a realização de um objetivo específico ou geral, que no caso da atividade física está relacionada à sua sistemática e, portanto, à manutenção de um estilo de vida melhor. Objetivo: a pesquisa se concentrou no diagnóstico da motivação para a prática de atividades físicas nos assistentes do Centro Gerontológico Las Piñas, no Cantão de Milagro. Materiais e métodos: a metodologia utilizada foi descritiva-explicativa, pesquisa qualitativa. Usando um método de amostragem não-probabilístico, 60 adultos mais velhos foram estudados como a população participante, classificada por gênero. Trabalhamos com um instrumento de pesquisa adaptado, aplicando o teste de Rossemberg como base, e uma pesquisa válida para medir as duas variáveis. Resultados: os resultados da pesquisa determinaram que existe uma alta porcentagem de adultos sedentários, em relação ao gênero, verificou-se que as mulheres têm uma taxa de inatividade maior que os homens, sem diferenças significativas (p=0,982). Outra resposta encontrada é que muitos adultos mais velhos acham que a percepção de não conseguir acompanhar os outros, doenças, medo de lesões, entre outros, são fatores limitantes para a atividade física, que são variáveis a serem consideradas no projeto prospectivo de uma estratégia recreativa para melhorar a qualidade de vida das amostras em estudo. Conclusões: como parte das conclusões, sugere-se que sejam feitas modificações no estilo de vida dos adultos mais velhos estudados, sendo o principal a motivação que pode ser incutida neles em casa e em suas famílias.

ABSTRACT Introduction: Motivation allows the individual to stay in a given action, enables the effectiveness of pertinent processes for the achievement of a specific or general objective, which in the case of physical activity is related to its systematicity and, therefore, the maintenance of a better lifestyle. Objective: The research focused on diagnosing the motivation towards the practice of physical activities in Assistants of the "Las Piñas" Gerontological Center of the Milagro Canton. Materials and methods: The methodology used responds to descriptive-explanatory research, of a qualitative nature. With a type of non-probabilistic sampling, 60 older adults are studied as a participating population, classified by gender. An adapted research instrument was used, applying the Rossemberg test as a basis and a valid survey for the measurement of the two variables. Results: The results of the research determined that there is a high percentage of adults who are sedentary, in relation to gender it was found that women have a higher rate of inactivity than men, without significant differences (p=0.982). Another response found is that many older adults find the perception of not being able to keep up with others, illnesses, fear of injury, among others, as limitations to physical activity, being variables of consideration n the prospective design of a strategy playful to improve the quality of life of the samples under study. Conclusions: As part of the conclusions, it is suggested that changes be made in the lifestyle of the older adults studied, the main thing is the motivation that can be instilled in them from home and from families.

Effects of disordered eating behaviors and sedentary lifestyle prevention program in male and female Mexican adolescents / Efectos de un programa de prevención de conductas alimentarias de riesgo y sedentarismo en adolescentes mexicanos, hombres y mujeres

Abstract Introduction Adolescents are the group with the highest risk of developing disordered eating behaviors (DEB). Preventing this problem is of the utmost importance due to the physical and psychological consequences. Objective To evaluate the effects of a universal prevention program for disordered eating behaviors (DEB), thin ideal internalization (TII), drive for muscularity (DM), and sedentary lifestyle among Mexican adolescents. Method A quasi-experimental study with repeated measures (pre-test, post-test, six-month, and one-year follow-up) was carried out in a non-probabilistic sample of 523 adolescents (46.7% of females) aged 15-19 years (Mage = 16.07). We worked in two private high schools, one of them was designed as control group (CG), and the other as intervention group (IG). For both, female and male adolescents', data were collected using the Brief Questionnaire for Disordered Eating Behaviors (BQDEB) and the short form of the International Physical Activity Questionnaire (IPAQ). To evaluate TII the Attitudes toward Body Figure Questionnaire was applied in females, while in males Drive for Muscularity Scale (DMS) was used. Results After one-year, repeated measures analyses of variance (ANOVAs) revealed a significant reduction of the mean DEBs scores both in female (p = .01) and male (p = .03) adolescents of the IG with respect to CG. In IG, females decreased significantly the mean TII score as well as the mean DM score in males. Physical Activity increased in IG females from pre-test to posttest; however, the effect was not maintained over time. Discussion and conclusion These findings have important implications for future interventions with Mexican adolescents. We must take sex differences into account to choose activities and strategies that will enhance the effects of the program.

Resumen Introducción Los adolescentes constituyen el grupo con mayor riesgo de desarrollar conductas alimentarias de riesgo (CAR). Prevenirlas es de suma importancia debido a las consecuencias físicas y psicosociales. Objetivo Evaluar los efectos de un programa de prevención universal en conductas alimentarias de riesgo (CAR), interiorización del ideal de delgadez (IID), obsesión por la musculatura (OM) y sedentarismo en adolescentes mexicanos. Método Estudio cuasi-experimental con medidas repetidas (pre-test, post-test, seguimiento a seis meses y un año) en una muestra no probabilística de 523 adolescentes (46.7% mujeres) de 15-19 años de edad (Medad = 16.07). Se trabajó en dos escuelas preparatorias privadas, una como grupo control (GC) y otra como grupo intervenido (GI). Para mujeres y hombres, los datos se recolectaron usando el Cuestionario Breve para Conductas Alimentarias de Riesgo (CBCAR) y la versión corta del Cuestionario Internacional de Actividad Física (IPAQ). Para evaluar el IID en mujeres, se utilizó el Cuestionario de Actitudes hacia la Figura Corporal (CAFC) y en hombres la Escala para Obsesión por la Musculatura (DMS). Resultados Después de un año, el ANOVA de medidas repetidas mostró una reducción significativa en la media de CAR, tanto en mujeres (p = .01) como en hombres (p = .03) del GI respecto al GC. En el GI, la media de IID en mujeres disminuyó significativamente, así como la media de OM en hombres. La actividad física aumentó en las mujeres del GI desde el pre-test hasta el post-test; sin embargo, el efecto no se mantuvo en el tiempo. Discusión y conclusión Estos hallazgos tienen implicaciones para futuras intervenciones con adolescentes mexicanos. Se deben tomar en cuenta las diferencias por sexo para elegir las actividades y las estrategias que potenciarían los efectos del programa.
