Change in the motivation pattern of adolescents before and after participation in a multidisciplinary health promotion program

Introduction: there is evidence that multidisciplinary interventions are an efficient approach to achieving weight loss and other health-related goals. However, dropout rates of these programs are high among adolescents. The suggestion is that understanding the motivation of individuals to participate in these projects is fundamental to developing strategies for permanence and, consequently, promoting better results.Objective: the main aim of this study was to describe the motivations of overweight adolescents participating in a multidisciplinary health promotion project.Methods: this qualitative study was conducted from March to July 2021 using the Bardin content analysis technique. The tool used for data collection was the semi-structured interview, analyzed means by the software QSR NVivo 11 by grouping the speech into clusters. These, in turn, were evaluated in three categories: (1) motivation, (2) food, and (3) physical exercise.Results: the age of the participants was 13.8 ± 2.4 years old, with body mass index of 31.8 ± 8.5 kg/m². Regarding family income, 41.66% had a monthly payment of 3 to 6 minimum wages. Regarding parents' educational level, 70.83% of mothers had completed higher education, while 29.16% had completed high school. According to the respondent's answers, weight loss was the greatest motivation to participate in a multidisciplinary obesity treatment program. In category 2, it was observed that adolescents associated the act of eating with feelings such as anxiety and nervousness. In category 3, the impact of the pandemic was found under the modalities of physical exercise practiced.Conclusion: the results describe the motivation of overweight adolescents to participate in a multidisciplinary program, in addition to elucidating participants' perception of their health and related habits, strategies for health promotion, and consequent improvement of the quality of life of these individuals.

Establishing a normative table for classifying body fat percentage in adolescents / Estabelecimento de uma tabela normativa para a classificação do percentual de gordura corporal em adolescentes

Backgroung: The World Health Organization (WHO) recommends the use of the body mass index (BMI) as a cost-effective method to assess the nutritional status at the population level. The increase of BMI is linked to a higher risk of other chronic non-communicable diseases (NCDs), particularly hypertension, type 2 diabetes mellitus (T2DM), dyslipidemias, and some types of cancer. The prevalence of obesity has increased worldwide, and this condition has dramatically affected children and adolescents. Obesity at a young age increases the chances of severe obesity and its complications in adults.Objective: This study aimed to establish cut-off points for body fat percentage in male and female adolescents aged 16 to 18 years using bioelectrical impedance (InBody 570®). Methods: Gender specific tables were proposed based on the percentiles 3, 5, 10, 15, 25, 50, 75, 85, 95 and 97. A total of 546 adolescents were included. Results: The body fat percentage cut-off points for the male group were: P3 = 6.0-7.0%; P5 = 7.1-8.9%; P10 = 9.0-9.8%; P15 = 9.9-11.7%; P25 = 11.8-15.5%; P50 = 15.6-21.9%; P75 = 22.0-27.8%; P85 = 27.9-36.0%; P95 = 36.1-38.0% and P97 ≥ 38.1%. For females, the cut-off points were: P3 = 9.5-10.0%; P5 = 10.1-11.0%; P10 = 11.1-11.8%; P15 = 11.9-14.0%; P25 = 14.1-19.0%; P50 = 19.1-27.1%; P75 = 27.2-29.0%; P85 = 29.1-39.9%; P95 = 40.0-51.0% and P97 ≥ 51.0%. Conclusion: The establishment of cut-off points for body fat percentage may improve the clinical assessment and management of overweight and obese adolescents.

Introdução: A Organização Mundial da Saúde (OMS) recomenda o uso do índice de massa corporal (IMC) como método custo-efetivo nível 1 para avaliar o estado nutricional na população. O aumento do IMC está associado a um maior risco de outras doenças crônicas não transmissíveis (DCNT), particularmente a hipertensão arterial sistêmica (HAS), diabetes mellitus tipo 2 (DM2), dislipidemias e alguns tipos de cânceres. A prevalência da obesidade tem aumentado em todo o mundo e essa condição tem afetado dramaticamente crianças e adolescentes. A obesidade em jovens, por sua vez, aumenta as chances de obesidade grave e suas complicações em adultos.Objetivo: Este estudo teve como objetivo estabelecer pontos de corte para o percentual de gordura corporal em adolescentes do sexo masculino e feminino de 16 a 18 anos, utilizando a bioimpedância elétrica (InBody 570®). Método: Tabelas específicas para o sexo masculino e feminino foram propostas, com base nos percentis 3, 5, 10, 15, 25, 50, 75, 85, 95 e 97. Foram incluídos 546 adolescentes. Resultados: Os pontos de corte do percentual de gordura corporal para o grupo masculino foram: P3 = 6,0-7,0%; P5 = 7,1-8,9%; P10 = 9,0-9,8%; P15 = 9,9-11,7%; P25 = 11,8-15,5%; P50 = 15,6-21,9%; P75 = 22,0-27,8%; P85 = 27,9-36,0%; P95 = 36,1-38,0% and P97 ≥ 38,1%. Para as mulheres, os pontos de corte foram: P3 = 9,5-10,0%; P5 = 10,1-11,0%; P10 = 11,1-11,8%; P15 = 11,9-14,0%; P25 = 14,1-19,0%; P50 = 19,1-27,1%; P75 = 27,2-29,0%; P85 = 29,1-39,9%; P95 = 40,0-51,0% e P97 ≥ 51,0%. Conclusão: O estabelecimento de pontos de corte para percentual de gordura corporal pode propiciar parâmetros para a melhoria da avaliação clínica, bem como para o tratamento da obesidade em adolescentes.

Efectos de dos programas de ejercicios resistidos en la aptitud física relacionada con la salud de mujeres obesas con síntomas de algia en las rodillas / Effects of two resistance exercise programs on the health-related fitness of obese women with pain symptoms in the knees

Introducción: El sobrepeso afecta negativamente al sistema cardiovascular y al osteomioarticular, favoreciendo el dolor en las articulaciones de las extremidades inferiores. Por lo tanto, se han aplicado estrategias para reducir el sobrepeso a través de cambios en el estilo de vida. Objetivo: investigar los efectos de dos programas de intervención multidisciplinares sobre la aptitud física relacionada con la salud de mujeres obesas con síntomas de dolor en las rodillas. Métodos: Se evaluó a mujeres entre 40 y 59 años con obesidad (n=59) en el tiempo pre y post intervención en antropometría, composición corporal, aptitud física, nivel de discapacidad en rodilla y cadera y calidad de vida relacionada con la salud. Se realizó un ensayo clínico aleatorizado de grupos paralelos, utilizando dos programas de ejercicio de resistencia y reeducación alimentaria, durante ocho semanas. Todos los participantes recibieron el mismo contenido de intervención nutricional y para ejercicios físicos se aleatorizaron en dos grupos, G1 siendo el "grupo de fuerza" utilizando máquinas (n=30), y G2 siendo el grupo de "entrenamiento funcional" (n=29). Veintiocho mujeres (G1=18 + G2=10) fueron incluidas en los análisis finales. Los grupos y el tiempo se evaluaron mediante análisis bidireccional de la varianza, con medidas repetidas. Se asumió una p < 0,05 para todos los análisis. Resultados: se identificó un efecto de tiempo, con valores más altos para la fuerza máxima de tracción lumbar isométrica (MILTS), luego del período de intervención en ambos grupos (p < 0.05). Sin embargo, para las otras variables investigadas, no se identificaron diferencias significativas (p > 0.05). Conclusión: La ausencia de resultados significativos para todas las variables, excepto FIMTL, puede estar justificada por la adherencia moderada de los participantes a las intervenciones (~ 59% a 66%) ya que el estudio se realizó durante el período de aislamiento social (COVID-19). Sin embargo, se cree que los modelos de intervención fueron positivos en el mantenimiento de las variables estudiadas.

Introduction: Overweight negatively impacts the cardiovascular system and osteomyoarticular, promoting pain in the joints of the lower limbs. Therefore, strategies have been applied to reduce overweight through lifestyle changes. Objective: to investigate the effects of two multidisciplinary intervention programs on the health-related physical fitness of obese women with pain symptoms in the knees. Methods: Women between 40 and 59 years of age with obesity (n=59) were evaluated in the pre- and post-intervention time regarding anthropometry, body composition, physical fitness, level of disability in the knee and hip, and health-related quality of life. A randomized clinical trial of parallel groups was conducted, using two resistance exercise programs and food re-education, for eight weeks. All participants received the same nutritional intervention content and for physical exercises were randomized into two groups, G1 being the "strength group" using machines (n=30), and G2 being the "functional training" group (n=29). Twenty-eight women (G1=18 + G2=10) were included in the final analyses. The groups and time were evaluated by two-way analysis of variance, with repeated measures. A p < 0.05 was assumed for all analyses. Results: a time effect was identified, with higher values for maximum isometric lumbar-traction strength (MILTS), after the intervention period in both groups (p < 0.05). However, for the other variables investigated, no significant differences were identified (p > 0.05). Conclusion: The absence of significant results for all variables, except FIMTL, may be justified by the moderate adherence of the participants to interventions (~59% to 66%) since the study was conducted during the period of social isolation (COVID-19). However, it is believed that the intervention models were positive in maintaining the variables studied.
