Effect of Physical Exercise Programs Based on Mobile Health and Ecological Momentary Assessment on the Physical and Mental Health, Cognitive Functions, and Social Environment of Adults in Developing Countries: A Systematic Review.

Background and Objectives: Although there is strong evidence of the positive effects of physical exercise on health, adherence to face-to-face exercise programs in the adult population is low, identifying several barriers that hinder their practice. There is research that demonstrates the viability of physical exercise programs with the use of Mobile Health in Ecological Momentary Assessment (EMA) mode, which contributes to overcoming many reported barriers. To synthesize the methodological characteristics and health effects of physical exercise programs based on mobile health in EMA modality in adults in developing countries. Materials and Methods: This systematic review was conducted according to guidelines established by the PRISMA statement in APA PsycArticles and CINAHL databases by EBSCOhost, Cochrane Library, PubMed, and Web of Science for articles published between 2008 and March 2024. Results: Telephone counseling on clinical-behavioral factors is believed to reduce morbidity and mortality in developed countries, but this aspect is not explored in developing countries. We included nine randomized controlled trials with a total of 4394 male and female participants aged 18 to 60 years. The interventions were mainly carried out by text messages, lasting between 20 to 80 min per session, 3 to 5 days per week, and most were carried out over 12 months. The interventions on the variables of physical activity, nutrition, and medical assessments showed significant effects, and variables such as quality of life and anthropometric measurements were not significant in most studies. Conclusions: This systematic review included studies from different developing countries, the most common diseases being diabetes, overweight, obesity, and hypertension. All the studies used mobile devices as the technology, finding a profile of the adults studied, as well as the characteristics of exercise programs based on mobile health in EMA modality.

Escolares participantes y no participantes de un programa de integración escolar de un establecimiento educacional público de la provincia del Biobío (Chile) presentan un similar estado nutricional, condición física y rendimiento académico

Introducción: Existe amplia evidencia sobre escolares chilenos con altos niveles de sobrepeso-obesidad, bajo nivel de actividad física y de condición física. Sin embargo, existe escasa evidencia que compare el estado nutricional, actividad física y condición física entre escolares participantes y no participantes de un programa de integración escolar. Objetivo: Analizar diferencias en el estado nutricional, la condición física y el rendimiento escolar entre escolares de tercero a quinto año básico participantes y no participantes de un programa de integración escolar de un establecimiento educacional público de la provincia del Biobío (Chile). Materiales y métodos: Estudio transversal, descriptivo y correlacional. se analizó una muestra por conveniencia de 107 escolares. Se midió el estado nutricional, la condición física. Además, para evaluar el rendimiento escolar se obtuvieron los promedios de notas de Lenguaje y matemáticas. Resultados: Se reportó una prevalencia de sobrepeso y obesidad ligeramente superiores a valores de referencia nacional. No existieron diferencias significativas entre el estado nutricional, condición física y rendimiento académico para los escolares participantes y no participantes del programa de integración escolar. Adicionalmente, los escolares con mayor índice de masa corporal tenían un promedio más bajo en la asignatura de Lenguaje y Comunicación. Conclusiones: La similitud en los niveles de estado nutricional, condición física y rendimiento escolar, así como la prevalencia de sobrepeso y obesidad asociada a un bajo rendimiento académico, debe tenerse en cuenta al momento de diseñar e implementar campañas de promoción de actividad física en escolares

Introduction: There is ample evidence on Chilean schoolchildren with high levels of overweight and obesity, and a low level of physical activity and physical fitness. However, there is little evidence that compares the nutritional status, physical activity, and physical fitness between participating and non-participating schoolchildren in mainstream education. Objective: To analyze differences in nutritional status, physical condition, and school performance among schoolchildren from the third to fifth grade participating and non-participating in mainstream education of a public educational establishment in the province of Biobío, Chile. Materials and methods: Cross-sectional, descriptive, and correlational study. A convenience sample of 107 schoolchildren was analyzed. Nutritional status and physical fitness were measured. In addition, to measure school performance, the grade point averages of language and mathematics were obtained. Results: A prevalence of overweight and obesity slightly higher than national reference values was reported. There were no significant differences between the nutritional status, physical condition, and school performance for the participating and non-participating schoolchildren in mainstream education. Additionally, the schoolchildren with the highest body mass index had a lower grade point average in language and communication. Conclusions: The similarity in the levels of nutritional status, physical fitness, and school performance, as well as the prevalence of overweight and obesity associated with low school performance, should be considered when designing and implementing program to promote physical activity in schoolchildren

Association of Physical Fitness, Screen Time, and Sleep Hygiene According to the Waist-to-Height Ratio in Children and Adolescents from the Extreme South of Chile.

OBJECTIVE: To analyze the perception of physical fitness, screen time, and self-reported sleep hygiene in children and adolescents (CA) from the extreme south of Chile and its associations with waist-to-height ratio (WtHr). MATERIAL AND METHODS: An observational cross-sectional study was conducted in a sample of 594 schoolchildren from 5th to 8th grade of primary education, belonging to municipal educational establishments in the Magallanes region, Chile. Cardiorespiratory fitness was assessed through the 20-m shuttle run test, muscle strength through handgrip and the standing broad jump test, physical fitness perception through the International Fitness Scale, and central obesity through the waist-to-height index. In addition, sleep hygiene and screen time were measured. RESULTS: More than 92% of CA spent more than two hours a day watching or using screens. In addition, CA with excess central adiposity had a lower perception of physical fitness, and lower muscle strength and cardiorespiratory fitness compared to CA with normal values of adiposity. CONCLUSIONS: CA of the present study spent a high number of hours watching or using screens and had poor sleep quality. In addition, excessive central adiposity was associated with lower physical fitness.

Comportamiento de la actividad física durante la pandemia por COVID-19 y su asociación con el bienestar subjetivo y salud mental en estudiantes universitarios en Chile / Behavior of physical activity during the COVID-19 pandemic and its association with subjective well-being and mental health in university students in Chile

Resumen Antecedentes La pandemia por COVID-19 ha impactado en la actividad física y salud psicológica de estudiantes universitarios. Objetivo Analizar el comportamiento de la actividad física durante la pandemia por COVID-19 y su asociación con el bienestar subjetivo y salud mental en estudiantes universitarios en Chile. Método Estudio transversal en una muestra de 469 estudiantes de diferentes universidades de Chile (67,4% mujeres, M= 21,7 DT= 2,45 años). Se midió el comportamiento de la actividad física, bienestar subjetivo y salud mental. Resultados Los estudiantes que mantuvieron un comportamiento físicamente activo antes y durante la pandemia presentaron mayor bienestar subjetivo (hombres: p = 0,020; y mujeres p <0,0001) que quienes se mantuvieron físicamente inactivos antes y durante la pandemia (mujeres M= 4,84, DE= 1,64; hombres M= 4,46, DT= 1,27). Las mujeres que se volvieron físicamente inactivas durante la pandemia tuvieron menos experiencias afectivas negativas que mujeres que eran inactivas antes de la pandemia ( F (3,293)=3,118; p =0,026). La sintomatología de salud mental se reportó con menor frecuencia en estudiantes físicamente activos que inactivos. Conclusión Estudiantes que se mantuvieron físicamente activos antes y durante la pandemia mostraron mejores indicadores de bienestar subjetivo y salud mental que quienes se mantuvieron físicamente inactivos o pasaron a ser físicamente inactivos durante la pandemia. La actividad física debe promoverse en la educación superior, debido a su potencial efecto protector en el manejo de consecuencias psicológicas durante una crisis pandémica.

Abstract Background The COVID-19 pandemic has impacted on the physical activity and psychological health of university students. Objective To analyze the physical activity during the COVID-19 pandemic and its association with subjective well-being and mental health in university students in Chile. Method Cross-sectional study in a sample of 469 students from different Chilean universities (67.4% women, M = 21.7 SD = 2.45 years). The physical activity, subjective well-being and mental health was measured. Results Students who maintained a physically active behavior before and during the pandemic presented higher subjective well-being (men: p = 0.020; and women p <0.0001) than those who were physically inactive before and during the pandemic (women M = 4 , 84, SD = 1.64; men M = 4.46, SD = 1.27). Women who became physically inactive during the pandemic had fewer negative affective experiences than women who were inactive before the pandemic (F (3,293) = 3.118, p = 0.026). Mental health symptoms were reported less frequently in physically active than inactive students. Conclusion Students who were physically active before and during the pandemic showed better indicators of subjective well-being and mental health than those who were physically inactive or became physically inactive during the pandemic. Physical activity should be promoted in higher education, due to its potential protective effect in managing psychological consequences during a pandemic crisis.

Association between the Physical Activity Behavioral Profile and Sedentary Time with Subjective Well-Being and Mental Health in Chilean University Students during the COVID-19 Pandemic.

OBJECTIVE: To analyze the association between the behavioral profile of physical activity and sedentary time with subjective well-being and mental health in university students during the COVID-19 pandemic in Chile. METHODS: Cross-sectional study in a voluntary sample of 469 university students (22.4 ± 0.19 years; 66% women). According to students' self-reports of physical activity and sedentary time, four behavioral profiles were created to investigate their association with subjective well-being and mental health using one-factor ANOVA that was adjusted to a multifactorial model. RESULTS: The physically inactive and sedentary behavior profile presents the lowest levels of subjective well-being (p < 0.001), positive affective experiences (p < 0.001) and general mental health (p = 0.001). When adjusting for confounding variables, it was observed that the physically active and non-sedentary profile was associated with better general mental health (p < 0.01) in contrast to those who are physically active and sedentary. CONCLUSIONS: Chilean university students with a physically inactive and sedentary profile during the pandemic presented worse well-being and mental health, with a sedentary lifestyle being one of the variables that most affects the mental health of these students. Therefore, measures should be implemented to encourage this population to maintain adequate levels of physical activity and reduce sedentary times.

Anxiety, Low Self-Esteem and a Low Happiness Index Are Associated with Poor School Performance in Chilean Adolescents: A Cross-Sectional Analysis.

OBJECTIVE: To analyze the relationship between anxiety, self-esteem, happiness index and primary school students' academic performance in Chilean adolescents from the Biobío province. METHODOLOGY: 733 (46.1% girls; 12 (1.3 years)) public primary school students that completed the 2018 Health and School Performance Survey carried out in the Biobío province were included in this cross-sectional analysis. The BECK Anxiety Inventory (BAI) was used to measure anxiety while happiness index and self-esteem were measured using the subjective happiness scale and the Rosenberg self-esteem scale, respectively. School performance was measured by grade point average (GPA) of language, math, physical education and cumulative GPA, and behavior associated with cognition in the school context was also considered. The relationship between mental health indicators and school performance was investigated using a one-way ANOVA and Pearson correlation. RESULTS: In comparison to students with low anxiety levels and high self-esteem and happiness levels, students with higher anxiety levels, lower self-esteem and happiness levels perceived themselves as having memory problems. They were also slower to solve math problems, had a shorter attention span in class and presented more difficulties in solving complex tasks, as well as being more nervous during testing. These students also got the lowest grade point average in math, language and physical education. CONCLUSIONS: High anxiety levels, low self-esteem and low happiness levels were associated with lower school performance and weaker behavior associated with cognition in Chilean adolescents. Implementing plans of emotional education and mental health could improve academic achievement.

Overweight/Obese Schoolchildren with Low Muscle Strength Have a Lower Cardiorespiratory Capacity and Greater Cardiovascular Risk: Results of the School Health Survey of the Extreme South of Chile 2019.

OBJECTIVE: To compare cardiovascular risk and cardiorespiratory capacity in schoolchildren from a region in the extreme south of Chile according to nutritional status and muscular strength. METHODS: An analytical cross-sectional study was performed on a sample of 594 schoolchildren from 5th to 8th grade in the extreme south of Chile. Based on body mass index and lower limb muscle strength, participants were divided into four groups: high strength-normal weight, high strength-overweight/obese, low strength-normal weight, and low strength-overweight/obese. Then, waist-to-height ratio and cardiorespiratory capacity, measured with the 20 m shuttle run test, were assessed to determine their cardiovascular risk, comparing the four groups. RESULTS: The overweight/obese group with high muscular strength presented better indicators in anthropometric variables (waist circumference and waist-to-height ratio) than their peers with low muscular strength. Additionally, the overweight/obese group with low muscular strength presented a lower cardiorespiratory capacity than their peers with high muscular strength. Both results were observed in boys and girls. CONCLUSION: The results of this study suggest that overweight/obese schoolchildren with high muscle strength present healthier anthropometric indicators and greater cardiorespiratory capacity than their peers with low muscle strength. These results confirm the relevance of measuring muscle strength in schoolchildren and its usefulness to assess functionality. These results encourage the scientific community to continue studying the role that muscle strength plays in modulating the effects of overweight and obesity on respiratory and cardiovascular conditions in childhood.

RESUMEN Fundamento: una intervención basada en ejercicio multicomponente favorecería la funcionalidad. Sin embargo, son escasos los estudios locales, en Chile, que los han utilizado. Objetivo determinar los efectos del ejercicio multicomponente en la disminución del riesgo de caída y riesgo de deterioro cognitivo, la mejora del equilibrio, fuerza muscular, capacidad funcional y calidad de vida en personas mayores que viven en comunidad. Métodos: estudio preexperimental pre-post sin grupo control. La muestra fue intencionada (n=17; 47,1 % mujeres; 70 años de mediana). Se aplicó un plan de ejercicio multicomponente durante nueve semanas. Pre y post ejercicio se evaluó equilibrio dinámico con el test Timed Up and Go, equilibrio estático con un oscilógrafo postural y la prueba de Estación Unipodal, fuerza muscular con el test de Sentarse y Levantarse, capacidad funcional con el test de Marcha 6 Minutos, calidad de vida con el Cuestionario SF-36 y sospecha de deterioro cognitivo con el Mini Mental State. Para determinar diferencias pre-post ejercicio se aplicó la prueba de Wilcoxon. Resultados: después de los ejercicios se observó un mejor rendimiento en las pruebas: Timed Up and Go (p=0,004), Estación Unipodal (p=0,023 pierna derecha, p=0,005 pierna izquierda), Sentarse y Levantarse (p=0,014), Marcha de 6 Minutos (p=0,006) y en el Cuestionario SF-36: dolor corporal (p=0,003), salud mental (p=0,000) y puntaje total (p=0,002). Conclusiones: un programa de ejercicio multicomponente de nueve semanas logró disminuir el riesgo de caídas, mejorar equilibrio, fuerza muscular, capacidad funcional y calidad de vida de personas mayores que viven en comunidad.

ABSTRACT Background: a multicomponent exercise-based intervention would favor functionality. However, there are few local studies, in Chile, that have used them. Objective to determine the effects of multicomponent exercise in reducing the falling and cognitive deterioration risks, improving balance, muscle strength, functional capacity and life quality in elderly people living in the community. Methods: pre-post experimental study without control group. The sample was intentional (n = 17; 47.1% women; median 70 years old). A multicomponent exercise plan was applied for nine weeks. Pre and post exercise, dynamic balance was evaluated with the Timed Up and Go test, static balance with a postural oscillograph and the Unipodal Station test, muscle strength with the Sit and Stand test, functional capacity with the 6 Minute Walk test, quality life with the SF-36 Questionnaire and suspected cognitive impairment with the Mini Mental State. To determine pre-post exercise differences, the Wilcoxon test was applied. Results: after the exercises, a better performance was observed in the tests: Timed Up and Go (p = 0.004), Unipodal Station (p = 0.023 right leg, p = 0.005 left leg), Sitting and Getting up (p = 0.014), 6-Minute Walk (p = 0.006) and in the SF-36 Questionnaire: body pain (p = 0.003), mental health (p = 0.000) and total score (p = 0.002). Conclusions: a nine-week multicomponent exercise program was able to reduce the risk of falls, improve balance, muscle strength, functional capacity and quality of life in older people living in the community.

Abstract Zapata Lamana, R., Fuentes Figueroa, V., Reyes Molina, D., Geisse Zárate, A. E. & Cigarroa, I. (2021). Methodological characteristics of studying commitment to the practice of physical activity and exercise in the general population: a systematic review. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(1), 1-23. Although the literature on sports commitment within the sports population is extensive, in-depth studies of the commitment to the practice of physical activity and exercise in the general population are needed. The aim of this paper was to synthesize the methodological characteristics of articles that have studied the commitment to the practice of physical activity and exercise in the general population. A systematic review was developed following the PRISMA statement. Furthermore, electronic searches were conducted in the PsycINFO and Medline databases from 2009 to 2019. A total of 14 articles was selected, mainly with cross-sectional designs. The most studied population included female university students with no clinical condition. All instruments used to assess commitment to physical activity and exercise were written in English, mostly applied in the United States, and used a Likert scale with high reliability. The main variables associated with the evaluation of commitment were age, gender, ethnic origin, educational and economic level, level of physical activity, behavior, eating disorders, and body mass index, as well as sociocognitive variables such as self-efficacy, social support, and perceived barriers and benefits of physical activity. This review provides a profile of the population in which the commitment to physical activity and exercise is evaluated, the instruments used, and associated variables, which updates the existing knowledge about the commitment to physical activity and exercise in the general population.
