Actividad física y calidad de vida relacionada con la salud en escolares: análisis mediante ecuaciones estructurales

Abstract

<p><span style="font-family: Garamond;">The aim of this research was to develop an explanatory model of body mass index (BMI), health-related quality of life, and physical activity, and to analyse the effects of the physical variables on the levels of physical activity, self-esteem and health-related quality of life. A cross-sectional study was conducted on a sample of 631 Spanish schoolchildren (12.5 ± 1.4 years old).<strong> </strong>They completed questionnaires on self-esteem (Rosemberg test), physical activity (PAQ-C), Mediterranean diet (KIDMED), quality of life (KIDSCREEN-27) and had their BMI and maximum oxygen uptake measured. Structural equations constituted the statistical analyses. A correlation was found between lower BMI and fewer hours of self-reported screen time which was also conducive to higher cardio-respiratory levels and greater engagement in physical activity. More physical activity and better dietary care were related generally with higher health-related quality of life and self-esteem. The model demonstrated acceptable goodness of fit. Findings of the study suggest physical activity and positive dietary behaviours should be promoted in Spanish schools as incremental improvements have the potential to concordantly improve a large range of healthful outcomes including health-related quality of life, self-esteem and BMI.</span></p>

The Reasons for Doing Physical Exercise Mediate the Effect of Self-Esteem on Uncontrolled Eating Amongst Nursing Personnel

“…Self-esteem is one of the most studied personal constructs in the scope of an organization, because of its close relationship to wellbeing and quality of life. Empirical research has been particularly interested in its study in nursing professionals—a group especially vulnerable to burnout due to the characteristics of the work setting where they perform their functions [6,8,12]. Self-esteem is also involved in adopting healthy living habits, such as an adequate eating style and doing physical exercise.…”

“…At the present time, the study of self-esteem is one of the research areas that has awakened the most academic and professional interest due to its close relationship with physical and psychological wellbeing [6], social adjustment [7], and quality of life [8]. High levels of self-esteem are also related to optimum academic performance [9] and higher job performance and commitment [10,11].…”

“…Promoting a healthy life style among employees is important because of its positive effect on their wellbeing as well as its consequences for the organization, i.e., the better the physical and mental health of the healthcare professionals, the higher the quality of the treatment offered to patients and their families will be [1,5]. Therefore, in recent years, there has been greater interest in studying eating and physical activity styles to prevent health-related problems (e.g., deficient clinical care, job absenteeism) [6,22].…”

Actividad física, consumo de drogas y conductas riesgo en adolescentes

“…En lo que respecta a la forma física, el 51.1% de los estudiantes que realizan deporte consideran que su forma física es muy buena, buena o moderada frente a aquellos que son sedentarios. Estos datos están en línea con los estudios que ponen de manifiesto que a mayor actividad física por parte de los adolescentes, mayor calidad de vida y por ende mayor autoestima y autoconcepto de la condición física y de la competencia física percibida (Zurita-Ortega et al, 2018).…”

“…Por lo que es necesario promover la actividad física atendiendo a las recomendaciones de la ACSM (Haskell et al, 2007). De este modo supondrá una mejora de la calidad de vida, la salud mental, la vitalidad, el autoconcepto y la autoestima (Palomino-Devia, Reyes-Oyola, & Sánchez-Oliver, 2018; Zurita-Ortega et al, 2018).…”
