Introduction: Parenting stress and parental adjustment could implicate key differences in the relational dynamics that parents establish with their children, particularly when families come from vulnerable social contexts. Method: Participants were 142 fathers and mothers from a risk neighborhood of Chile. The variables examined were parenting stress (parental distress, parent–child dysfunctional interaction and difficult child) and parental adjustment (depression, anxiety, and stress). Parents also completed a sociodemographic characterization survey. The statistical analyses were a correlation analysis and multiple linear regression analyses. Results: Overall, not all components of parenting stress were related to parental adjustment. Only parental distress was found as a significant predictor of poor parental adjustment (greater depression, anxiety, and stress), but not parent–child dysfunctional interaction and having a difficult child. Conclusions: The present study findings highlight the influence of stress on parenting as a relevant dimension of research for the improvement of the intervention deployed by the state regarding the protection of vulnerable Chilean children, providing multiple clinical and psychosocial applications for research and intervention purposes.

El propósito del presente estudio fue analizar la pertinencia del contenido de la Batería MOBAK para evaluar el desarrollo del eje de objetivos de habilidades motrices, establecidos para asignatura de Educación Física. Se adoptó una metodología exploratoria para establecer la validación del contenido en tres fases: Conceptualización de habilidades motrices; índice de validación de contenido (IVC) por comité de especialistas; y encuestas a profesores de Educación Física. Los resultados indican que en la descripción de las habilidades motrices presentada en las Bases Curriculares y en la Batería MOBAK existen diferencias de categorización, pero no de conceptualización. El índice de validez del contenido establece un alto nivel de confiabilidad (IVC=0,81). La encuesta a profesores indica una alta pertinencia de las tareas motrices con los objetivos de aprendizaje. La Batería MOBAK se presenta como un instrumento válido para diagnosticar y monitorear el desarrollo de las habilidades motrices en la asignatura de Educación Física.

The purpose of this cross-cultural study was to determine the association between the sociodemographic background of a child’s parents (i.e., their socioeconomic level, marital status, and educational level) with the child’s lifestyle (i.e., Mediterranean diet (MD), physical activity (PA) and screen time (ST)), and health markers. Material: This cross-sectional study included 1273 children, from Chile (n = 496), Colombia (n = 340), and Spain (n = 437). The sociodemographic information together with the lifestyle and health markers of the children were measured. There was an inverse association between a low or medium-low socioeconomic level for the parents of Chilean children and handgrip strength (β −0.61, p < 0.001); meanwhile, for Spanish children, an inverse association between a low or medium-low socioeconomic level and PA after school (β −0.58, p = 0.016), lifestyle (β −0.74, p = 0.015), and with MD adherence (β −0.86, p = 0.004) was found. The risk (i.e., by odd ratios (OR)) of being divorced/separated parents marital status showed an inverse association with abdominal obesity (OR 0.21, p = 0.045) in Spanish children; however, the parent’s marital status and a low educational level were risk factors for the suffering of a low nutritional level in Colombian children (OR 2.02, p = 0.048; OR 2.49, p < 0.001, respectively). On the other hand, a low educational level for parents reported for Chilean children had a positive association with ST of ≥4 h per day (OR 1.82, p = 0.020). In conclusion, in Spanish-speaking children, the lifestyle and health markers of the children are affected by the sociodemographic background of their parents; however, these effects could be moderated by the socio-cultural and economic status of their countries as members of the OCDE; therefore, it is essential to develop policies that decrease these gaps, so that children who are under-resourced can reach their full potential.

This study is linked to teacher evaluation. Its objective was to determine the factors that, according to teachers of basic education in the municipality of Osorno, affected the outcome of their teacher assessment 2015 and 2016. A written interview with open questions was applied to poorly evaluated teachers. Among the results, it was found that the operational way of dealing with the evaluation was individual, without the support of peers or consultants. They had little time for preparation. They assume an excess of confidence, reflected in the fact that they gave little importance to the process. They recognize feeling a deep disappointment, insecurity, accompanied by feelings of frustration, a mixture of emotions accentuated by the disloyalty with which their colleagues acted. They state that they did not receive support or understanding in the face of poor results, an attitude that, in their opinion, constitutes the most negative emotional burden of this evaluation process.

Objetivo: Comparar la composición corporal por antropometría clásica e impedancia bioeléctrica en estudiantado universitario de una universidad peruana. Método: Estudio correlacional, transversal, conformado por 152 estudiantes (77 varones y 75 mujeres) matriculados en el ciclo 2018-II con edad promedio de 20.45 ± 3.63 años. Se calculó para el método de antropometría el índice de masa corporal, mediciones antropométricas y se utilizó la ecuación de Yuhasz (1974) para determinar el porcentaje de grasa corporal, y para el de bioimpedancia eléctrica se utilizó el analizador tetrapolar multifrecuencia de medición segmental directa Inbody 120. Para establecer la correlación se utilizó el coeficiente de Pearson y para la concordancia se utilizó el método gráfico de Bland Altman e índice de estabilidad. Los datos fueron analizados con el programa estadístico IBM SPSS Statistics, versión 27.0. Para todos los análisis se utilizó un nivel de significancia (p<0.05). Resultados: Existe una fuerte correlación estadísticamente significativa (p<0.01y r=0.95) entre los métodos de antropometría y bioimpedancia eléctrica para la determinación del porcentaje de grasa corporal; además, una buena concordancia según el método gráfico de Bland Altman, reforzada con el índice de estabilidad para complemento de la interpretación (IE= 95 %). Conclusiones: Ambos métodos son intercambiables entre sí, por lo que pueden ser usados indistintamente en este tipo de población para determinar el porcentaje de grasa corporal expresado en porcentaje.

Objetivo: Analizar las características antropométricas de futbolistas profesionales del club deportivo Ñublense divididos de acuerdo a la posición que ocupan en el campo de juego. Método: Participaron ciento cincuenta y ocho (n=158) jugadores profesionales de Futbol divididos en Arqueros (AR) Defensas (DEF) Volantes (VOL) y Delanteros (DEL), todos pertenecientes al Club Deportivo Ñublense de la ciudad de Chillan, Chile. Se realizó una valoración de la composición corporal utilizando el fraccionamiento en 5 componentes, somatotipo, índice de masa corporal, suma de seis pliegues cutáneos y la relación músculo-óseo, siguiendo el protocolo de la International Society for the Advancements of Kinanthropometry (ISAK). Resultados: En cuanto a la composición corporal se obtuvieron valores porcentuales de Masa Adiposa=21.7%, Masa Muscular=48.9%, Masa Residual=12.4%, Masa Osea=11.4% y Masa Piel=5.2%. En relación al somatotipo se obtuvo una clasificación mesomorfico balanceado con valores medios 2.5-5.4-2.1. Conclusión: Los jugadores profesionales del club de futbol Ñublense de acuerdo a la posición que ocupan en el terreno de juego, presentan un somatotipo similar al de otros futbolistas nacionales e internacionales, donde predomina el componente mesomórfico balanceado. Sin embargo, se observa una elevación de los porcentajes de masa adiposa (MA) y una menor talla, en comparación a futbolistas internacionales, lo que pueden determinar claras diferencias en el rendimiento respecto a las posiciones de juego en situaciones competitivas. Objective: Analyze the anthropometric characteristics of Chilean professional soccer players divided according to the position they occupy in the field of play. Method: One hundred and fifty-eight (n = 158) professional soccer players divided into Archers (AR) Defenses (DEF) Volantes (VOL) and Forwards (FOR), with average Age values (24.2 ±4.76 years, body mass 75.0±7.28 kg and height 175.7±6.32 cm.), All belonging to the Ñublense Sports Club of the city of Chillan, Chile. An assessment of the body composition was made using the 5 component fractionation, somatotype, body mass index, sum of six skinfolds and the muscle-bone relationship, following the protocol of the International Society for the Advancements of Kinanthropometry. Results: Regarding body composition, mean values of Adipose Mass = 21.7%, Muscular Mass = 48.9%, Residual Mass = 12.4%, Bone Mass = 11.4% and Skin Mass = 5.2% were obtained. In relation to the somatotype, a balanced mesomorphic classification was obtained with mean values 2.5 - 5.4 - 2.1. Conclusion: According to the position they occupy on the pitch, the professional players of the Ñublense soccer club present a somatotype similar to that of other national and international soccer players, where the balanced mesomorphic component predominates. However, there is an increase in the percentages of adipose mass (AM) and a smaller stature, compared to international soccer players, which can determine clear differences in performance with respect to playing positions in competitive situations.
