RESUMO
Childhood overweight and obesity represent a growing public health problem worldwide. Since the 1980s, the global prevalence of overweight and obesity in childhood and adolescence has increased by 47%. The promotion of exercise is an important intervention to reduce the physical damage of obesity. The meta-analysis was conducted in accordance with the general guidelines for the reporting of systematic reviews and meta-analyses (PRISMA). The PubMed, SciELO, ScienceDirect and Google Scholar databases were searched from August to December 2021. The search yielded 722 titles published between 2000 and 2021. After screening the titles and abstracts, 64 duplicate articles were detected, and 27 articles were ultimately included in the systematic review, including 26 articles published in English and one published in Spanish. There was a statistically significant effect of the strength training interventions on the percentage of body fat, Test of 0 i = (p = 0.00, z = 6.92), Test of 0 = (p = 0.00, Q (9) = 42.63). The findings reveal that strength training has a positive impact on the treatment of body fat in children and adolescents with overweight and obesity.
RESUMO
Obesity is a disease characterized by an inflammatory process in the adipose tissue due to diverse infiltrated immune cells, an increased secretion of proinflammatory molecules, and a decreased secretion of anti-inflammatory molecules. On the other hand, obesity increases the risk of several diseases, such as cardiovascular diseases, diabetes, and cancer. Their treatment is based on nutritional and pharmacological strategies. However, natural products are currently implemented as complementary and alternative medicine (CAM). Polyphenols and fiber are naturally compounds with potential action to reduce inflammation through several pathways and play an important role in the prevention and treatment of obesity, as well as in other non-communicable diseases. Hence, this review focuses on the recent evidence of the molecular mechanisms of polyphenols and dietary fiber, from Scopus, Science Direct, and PubMed, among others, by using key words and based on recent in vitro and in vivo studies.
RESUMO
Human immunodeficiency virus (HIV) infection has continued to be the subject of study since its discovery nearly 40 years ago. Significant advances in research and intake of antiretroviral therapy (ART) have slowed the progression and appearance of the disease symptoms and the incidence of concomitant diseases, which are the leading cause of death in HIV+ persons. However, the prolongation of ART is closely related to chronic degenerative diseases and pathologies caused by oxidative stress (OS) and alterations in lipid metabolism (increased cholesterol levels), both of which are conditions of ART. Therefore, recent research focuses on using natural therapies to diminish the effects of ART and HIV infection: regulating lipid metabolism and reducing OS status. The present review summarizes current information on OS and cholesterol metabolism in HIV+ persons and how the consumption of certain phytochemicals can modulate these. For this purpose, MEDLINE and SCOPUS databases were consulted to identify publications investigating HIV disease and natural therapies and their associated effects.

Objetivo: determinar la relación entre obesidad y anormalidades de parámetros cardiopulmonares en escolares. Materiales y métodos: participaron 78 escolares entre 5 a 11 años de edad, 47 hombres (60,3%) y 31 mujeres (39,7%), pertenecientes a una escuela primaria particular de la ciudad de Pachuca (México). Se evaluó: índice de masa corporal (IMC), circunferencia de cintura (CC), grasa corporal (GC), frecuencia cardiaca (FC), presión arterial (PA), frecuencia respiratoria (FR) y espirometría. Se emplearon las pruebas estadísticas chi-cuadrado (x2), odds ratio y correlación de Spearman (rs). Resultados: 23,1% de los escolares evaluados presentaron sobrepeso y 29,5%, obesidad. El 38,5 y 11,5% presentaron FC y PA superiores a los parámetros normales, respectivamente; 3,8% de la población presentó FR arriba del promedio y 11,5% mostró valores espirométricos anormales. Se encontraron relaciones entre IMC con GC y CC, GC y CC, CC y FC, GC y PA, y FC y FR. Conclusiones: las prevalencias de sobrepeso y obesidad obtenidas en este estudio fueron altas. Los niños con sobrepeso u obesidad podrían tener mayor riesgo de presentar anormalidades cardiopulmonares en comparación con niños de peso normal. Se sugiere continuar con estudios en el tema en una muestra más amplia.
Objective: Determine the relationship between obesity and abnormal cardiopulmonary parameters in school children. Materials and Methods: The sample involved 78 children between five and 11 years of age: 47 males (60.3%) and 31 females (39.7%). All were enrolled in a specific elementary school in the city of Pachuca (Mexico). Body mass (BMI), waist circumference (WC), body fat (GC), heart rate (HR), blood pressure (BP), respiratory rate (RR) and spirometry were evaluated. A chi-square (x2) statistical test, the odds ratio and Spearman's rank-order correlation (rs) were used. Results: In all, 23.1% of the students who were evaluated were overweight and 29.5% were obese; 38.5% and 11.5% had a HR and BP above the normal parameters, in that order; 3.8% of the population in question had a HR above average and 11.5% showed abnormal spirometric values. A relationship was found between BMI and BF and WC, BF and WC, WC and HR, BF and BP, and HR and RF. Conclusions: The prevalence of overweight and obesity found in this study was high. Children who are overweight or obese might be at increased risk of experiencing cardiopulmonary abnormalities compared to children of normal weight. It is suggested that studies on this subject be continued with a broader sample.
Objetivo: determinar a relação entre obesidade e anormalidades de parâmetros cardiopulmonares em estudantes do ensino fundamental. Materiais e métodos: participaram do estudo 78 estudantes entre 5 a 11 anos de idade, 47 do gênero masculino (60,3%) e 31 do feminino (39,7%), pertencentes a uma escola primária particular da cidade de Pachuca (México). Avaliaram-se o índice de massa corporal (IMC), a circunferência de cintura (CC), a gordura corporal (GC), a frequência cardíaca (FC), a pressão arterial (PA), a frequência respiratória (FR) e a espirometria. Utilizaram-se os testes estatísticos qui-quadrado (x2), odds ratio e correlação de Spearman (rs). Resultados: 23,1%o dos estudantes avaliados apresentaram excesso de peso e 29,5% obesidade. 38,5 e 11,5% apresentaram FC e PA superiores aos parâmetros normais, respectivamente; 3,8% da população apresentou FR acima da média e 11,5% mostraram parâmetros espirométricos anormais. Constataram-se relações entre IMC com GC e CC, GC e CC, CC e FC, GC e PA, e FC e FR. Conclusões: as prevalências de excesso de peso e obesidade obtidas neste estudo foram altas. As crianças com excesso de peso ou obesidade poderiam ter maior risco de apresentar anormalidades cardiopulmonares em comparação às de peso normal. Sugere-se continuar com estudos sobre o tema com uma amostra mais ampla.
