RESUMO
BACKGROUND: the prevalence of overweight and obesity in the child population is a global public health problem, with measures such as the promotion of physical activity being necessary. One of the recognized factors for this is the development of motor competence, due to its dynamic interaction with physical activity, so it is necessary to understand its relationship with weight status. OBJECTIVE: the aims of this study are to determine whether there are differences in the levels of motor competence of schoolchildren in Chilean Patagonia according to their nutritional status, as well as to determine the association between body mass index (BMI) and the levels of motor competence in these schoolchildren. MATERIAL AND METHODS: we evaluated 295 boys and girls in 5th and 6th grade of primary school, from educational centres in Coyhaique and Punta Arenas. We used the MOBAK 5-6 test to assess their motor competence. RESULTS: schoolchildren with normal weight status presented higher values of motor competence in self-movement (M = 3.1; SD = 1.84) compared to overweight (M = 2.7; SD = 1.68) and obese schoolchildren (M = 1.7; SD = 1.57), presenting significant differences between all groups (p < 0.001). In object control, no differences were found between the groups. In addition, there was an inverse association of object control with gender (ß: 1.49; p < 0.001) and BMI (ß: -0.05; p = 0.026), while self-movement had an inverse association with BMI (ß: -0.11; 95 % CI: -0.15 -0.07; p < 0.001). CONCLUSION: weight status and motor competence are associated. Schoolchildren with higher BMI values tend to perform lower in self-movement. These results underline the importance of addressing motor competence in efforts to combat overweight and obesity in children.
RESUMO
RESUMEN Objetivo: Asociar el nivel de conocimiento y prácticas (hábitos y costumbres) responsables de la transmisión de Triquinelosis, Síndrome Cardiopulmonar por Hantavirus y Equinococosis quística (Hidatidosis), en habitantes de los sectores rurales. Material y método: Estudio descriptivo correlacional de corte transversal en el que se aplicó una encuesta a 149 habitantes residentes en el área rural de las localidades de Curacautín, Lonquimay y Melipeuco, a través de muestreo no probabilístico por conveniencia, durante los meses de diciembre 2013 a enero 2014. Resultados: La población posee mejores conocimientos de Triquinelosis y Hanta que Hidatidosis, 64,9, 72,8 y 39,3%, respectivamente; los hábitos y costumbres para Hanta e Hidatidosis alcanzan mejores prácticas (84% cada una) que para Triquinelosis (69,5%); la población reconoce correctamente reservorio, fuente de infección y mecanismos de transmisión en Triquinelosis y Hanta, pero en menor grado Hidatidosis; respecto de los hábitos y costumbres, aun desconociendo los fundamentos teóricos, reportan buenas prácticas, aunque mantienen algunas que favorecen la transmisión de infecciones predominantemente en Triquinelosis. Conclusión: El nivel de conocimiento no asegura buenas prácticas, además los conocimientos y prácticas siguen un patrón empírico más que cognitivo, respaldados por aspectos culturales y del entorno. Esto sugiere mayor participación de los equipos interdisciplinarios en comunidades aisladas para fortalecer la promoción, educación y refuerzo de las buenas prácticas de acuerdo con sus condiciones sociales e incentivar la adherencia a conductas que reduzcan el riesgo de la transmisión de zoonosis.
ABSTRACT Objective: To associate the level of knowledge and practices (habits and customs) responsible for the transmission of trichinellosis, Hanta and cystic echinococcosis (hydatidosis), among rural population. Material and method: Cross-sectional correlational descriptive study in which 149 residents of the rural areas of Curacautín, Lonquimay and Melipeuco were surveyed, using non-probability convenience sampling from December 2013 to January 2014. Results: The population has better knowledge of trichinellosis and Hanta than hydatidosis, 64.9%, 72.8 and 39.3% respectively; they also have better practices regarding Hanta and hydatidosis (84% each) than regarding trichinellosis (69.5%). The population recognizes correctly the reservoir, source of infection and transmission mechanisms of trichinellosis and Hanta, and to a lesser degree hydatidosis; they report good practices regarding habits and customs, even ignoring theoretical foundations, but maintain some practices that favor the transmission of infections related to trichinellosis. Conclusion: The level of knowledge does not ensure good practices. Additionally, knowledge and practices follow an empirical rather than cognitive pattern, rooted on cultural and environmental aspects. This suggests greater participation of interdisciplinary teams in isolated communities to strengthen the promotion, education and reinforcement of good practices in accordance with their social conditions and to encourage adherence to behaviors that reduce the risk of the transmission of zoonoses.
