Is There a Relationship between Anthropometric Indices and Muscular, Motor, and Cardiorespiratory Components of Health-Related Fitness in Active European Older Adults?

The aging process induces alterations in the body, resulting in changes in both health-related fitness and specific anthropometric measures. These changes often pose health risks for older adults. The aim of the present study was to investigate whether there is an association between anthropometric indices and muscular, motor, and cardiorespiratory components of health-related fitness in active European older adults. This study included 2687 European older adults, comprising 1999 women and 688 men, with an average age of 70.05 ± 5.5 years. The assessment included health-related fitness using the Senior Fitness Test and anthropometric indices, such as the body adiposity index, body mass index, conicity index, waist-to-hip ratio, and waist-to-height ratio, among others. The results indicated that gender significantly influences the values of physical performance and anthropometric parameters, making them incomparable. The degree of correlation between anthropometric indices and muscular, motor, and cardiorespiratory components of fitness depends on each anthropometric index analysed. The anthropometric index most correlated with physical fitness performance parameters is the waist-to-height ratio (WHR), followed by the body mass index (BMI). Cardiorespiratory endurance and balance are the two physical parameters most correlated with anthropometric indices.

School Bullying and Dating Violence in Adolescents: A Systematic Review and Meta-Analysis.

Involvement in bullying perpetration or victimization could be risk factors for perpetration or victimization in early romantic relationships that emerge within an evolving peer group. Nevertheless, research on this topic is still in its early stages. This study was conducted to fill these gaps in knowledge through a comprehensive research synthesis. After systematic searches and application of inclusion and exclusion criteria, 23 projects that reported relations between bullying (perpetration and victimization) and dating violence (perpetration and victimization) were included in this meta-analysis. Bullying perpetration was related to dating violence perpetration (odds ratio [OR] = 1.98), and this relation held after adjusting for covariates (OR = 1.29). Moderator analyses showed that this effect was significant for males and females and stronger in cross-sectional studies. There was also a significant relation between bullying perpetration and dating violence victimization (OR = 2.59), but this was much weaker after controlling for covariates (OR = 1.09) and stronger for males and in longitudinal studies. Bullying victimization was related to dating violence victimization (OR = 2.51), also after adjusting for covariates (OR = 1.96), stronger for females and longitudinal projects. The relation between bullying victimization and dating violence perpetration was not statistically significant (unadjusted OR = 1.43, adjusted OR = 1.01). More research is needed to confirm these results, but this meta-analysis suggests that bullying and dating violence could be different behavioral manifestations, in different evolutionary moments and in different contexts, of the same underlying antisocial or violent dispositions, although longitudinal studies are needed to confirm this. Tailored and comprehensive interventions could be useful to tackle both problem behaviors.
