Effects of exercises performed in the work environment on occupational stress: A systematic review.

INTRODUCTION: Technological advances stimulate labor transformations in such a way that the search for productivity, goals and market competitiveness leads industries and companies to neglect the health and safety of their workers. There is a gap in the literature regarding means of intervention using physical exercises (PE), with details remaining unknown in terms of appropriate exercise prescriptions or types that minimize the effects of occupational stress. OBJECTIVE: to verify the effects on workers' stress of PE performed in the work environment. METHOD: this systematic review searched for randomized controlled trials (RCTs) in 08 databases (MEDLINE, Cochrane, BIREME, LILACS, EBSCOhost, SCOPUS, Web of Science and Embase), in English and Portuguese, published between 2017 and 2021. The PICOS strategy was used to determine inclusion, being P: male and female workers; I: exercises performed in the work environment; C: control group without intervention; O: occupational stress; and S: controlled experiments. Methodological quality, risk of bias and reliability of assessments were analyzed using the TESTEX, Risk of Bias 2, and Kappa scales. RESULTS: A total of 07 articles were included, of which, most had good methodological quality and unclear risk of bias. The intra- and inter-rater reliability test of methodological quality showed excellent agreement. As a limitation, the fragility in allocation concealment, blinding and absence of treatment analysis was noted in the studies evaluated. CONCLUSION: PE in the workplace might have positive effects on reducing occupational stress, but further studies must be conducted to better clarify this. This review was registered with PROSPERO (CRD42022304106).

Prevalencia de sobrepeso y obesidad en estudiantes de una ciudad de la región sureste del Brasil / Prevalence of overweight and obesity in students of a city of the southeast region of Brazil

Introducción: La prevalencia de sobrepeso y obesidad a temprana edad está creciendo en proporciones epidémicas y se ha convertido en una preocupación de la salud pública, tanto en los países desarrollados como en países en desarrollo. Objetivos: Analizar y describir la prevalencia de sobrepeso y obesidad en niños de una ciudad del interior de una región del Sureste de Brasil. Métodos: Se trata de un estudio transversal, de carácter descriptivo e inferencial, en el cual se observaron 263 niños de diez a quince años de edad, 147 del sexo masculino y 116 del sexo femenino. Participaron en el estudio los estudiantes matriculados en dos escuelas públicas municipales de enseñanza fundamental. Las mediciones antropométricas se realizaron siguiendo las recomendaciones internacionales de la International Standards for Kinanthropometric Assessment y el índice de masa corporal se determinó usando la fórmula sugerida por la Organización Mundial de la Salud. Resultados: En cuanto a la prevalencia de sobrepeso y obesidad entre niños y niñas, se encontró que 23,2 por ciento de los estudiantes tenían sobrepeso y que el 12,2 por ciento, estaban con obesidad. Sin embargo, cuando se estratificó por sexo, el sobrepeso y la obesidad eran más frecuentes en las niñas (27,6 por ciento - 9,5 por ciento) que en los niños (19,7 por ciento- 15,5 por ciento), respectivamente. Conclusiones: La prevalencia de sobrepeso y obesidad entre los estudiantes de la presente investigación se mostró alta, lo cual demuestra la necesidad de programas de prevención e intervención(AU)

Introduction: The prevalence of overweight and obesity at an early age is growing in epidemic proportions and becoming a public health concern-in both developed and developing countries. Objectives: To analyze and describe the prevalence of overweight and obesity in children from a city in the interior of a region of southeastern Brazil. Methods: This is a cross-sectional, descriptive and inferential study, in which 263 children from ten to fifteen years of age were observed, 147 being male and 116 female. Students enrolled in two municipal public elementary schools participated in the study. The anthropometric measurements were made following the international recommendations of the International Standards for Kinanthropometric Assessment and the body mass index (BMI) was determined using the formula suggested by the World Health Organization. Results: In terms of the prevalence of overweight and obesity among boys and girls, it was found that 23,2 percent of the students were overweight and that 12.2 percent were overweight. However, when stratified by sex, overweight and obesity were more frequent in girls (27,6 percent- 9,5 percent), than in boys (19,7 percent - 15,5 percent), respectively. Conclusion: The prevalence of overweight and obesity among the students of this research was high, demonstrating the need for prevention and intervention programs(AU)
