Weight status, physical activity and self-concept in primary school children

Abstract

Objective: The self-concept, self-esteem and body image of schoolchildren is being compromised due to stigmatization and discrimination in many areas of their lives. Recent studies have shown different associations between those variables and fitness. The objective of this study was to analyse the relationship between weight status, physical activity and self-concept in 103 schoolchildren (63 girls) aged 8-12 years. Design and method: The design was cross-sectional relational. The sampling was non-probabilistic. The body mass index was calculated and the participants were categorized according to their weight status (normal weight vs. overweight-obesity) following international criteria. Physical activity (minor vs. major) was estimated with the short Krece-Plus test. The self-concept was evaluated with the Piers-Harris Self-concept Scale. Non-parametric statistics were used. Results: The results showed that those with normal weight had a better behavioural self-concept (p = 0.048). Those with greater physical activity scored higher in the intellectual (p = 0.034), physical (p = 0.016), social (p = 0.031) and global (p = 0.008) dimensions. The fat but fit paradox was also found in the self-concept; thus, those with normal weight/ greater physical activity presented a better intellectual self-concept (p = 0.022), physical (p = 0.006) and global (p = 0.008). Conclusions: These findings suggest that weight status and physical activity could be differentiating elements in the self-concept in childhood and preadolescence. Prospective studies are needed to analyse the effects in this relationship.

Body appreciation as a multifactorial construct in adolescent athletes and their athletic achievements

“…In adolescents, body dissatisfaction has been found in the range between 12 and 16 years of age without significant differences between sexes (Baile et al, 2002); significant relationships between body appreciation and body mass index, as well as body appreciation and self-esteem (Jauregui & Bolaños, 2011); greater body appreciation but high indices of body pressure by context (Sundgot et al, 2021) and greater body appreciation in those who practice some sport, than in those who do not (Fischetti et al, 2020;Soulliard et al, 2021); similarly, high levels of body appreciation have been found in those adolescents who have high levels of physical activity (Rosa, 2019).…”

“…El tejido muscular esquelético disminuye alrededor de un 40% entre los 20 y los 60 años, sin embargo, a través del ejercicio físico se puede revertir parcialmente la pérdida de masa muscular y consecuentemente los niveles de fuerza (Doherty, 2003). Con el envejecimiento, ocurren cambios en la composición corporal, como aumento de la adiposidad y disminución de la masa corporal magra, en particular la masa muscular esquelética (St-Onge, 2005;Guillamon & Cantó, 2017). Jansen et al (2002), determinaron los puntos de corte para clasificar la sarcopenia mediante la cuantificación de la masa muscular (kg) por BIA corregido para la talla (m2), que establece el Índice de Masa Muscular (IMM).…”
