Objective: The aim of this study was to assess the association between overnutrition and scholastic achievement (SA).
Methods: A representative and proportional sample of 477 children of the 5th elementary school grade of both genders was randomly chosen during 2010, in the Metropolitan Region of Chile. SA was measured through the 2009 Education Quality Measurement System (SIMCE) tests of language (LSA), mathematics (MSA) and understanding of the natural environment (UNESA). Current nutritional status was assessed through the body mass index Z-score (Z-BMI). Nutritional quality of diet, schedule exercise, socioeconomic status, family, and educational variables were also recorded. Four and 8 years later, SA was assessed through the 2013 SIMCE and the University Selection Test (2017 PSU), respectively.
Results: Socioeconomic status, the number of repeated school years, and maternal schooling were strong predictors of 2009 SIMCE and the independent variables with the greatest explanatory power for LSA (Model R2 = 0.178; p < 0.00001) variances, besides of gender for MSA (Model R2 = 0.205; p< 0.00001) and UNESA (Model R2 = 0.272; p < 0.00001). Overnourished children did not have significantly lower 2009 and 2013 SIMCE and 2017 PSU outcomes.
Conclusions: These results confirm that overnourished children did not achieve significantly lower SA.

The critical role of cardiorespiratory fitness in disease prevention.

Cardiorespiratory fitness (CRF) has been increasingly recognized in recent years as an important predictor of risk for adverse outcomes in numerous chronic conditions. In fact, a growing body of epidemiological and clinical evidence demonstrates that CRF is a potentially stronger predictor of mortality than established risk factors such as smoking, hypertension, hyperlipidemia, and type 2 diabetes. Moreover, adding CRF to these traditional risk factors significantly improves the reclassification of risk for adverse outcomes.

Although physical activity has positive physical and mental health outcomes, particularly among adolescents, a significant percentage of young people maintain a largely sedentary lifestyle. Considering that the youths spend the greater part of the day at school, this is considered an ideal setting to foster active and healthy living. Consequently, this study is intended to investigate the connection between physical activity, self-efficacy and academic achievement in normal-weight and overweight adolescents.

Residential greenness exposure has been reported to positively impact health mainly by reducing overweight/obesity risk, improving mental health and physical activity. Less is known on biological pathways involved in these health benefits. We aimed to investigate the association between multisite greenness exposure and oxidative stress in children and explore the potential mediating role of physical activity in this association.
