“…Specifically, the CRF was positively but weakly correlated with academic achievement only in boys. This positive correlation is also presented in other studies in children and adolescents where higher CRF was related to increased mean academic attainment in both boys and girls [39,40]. Nevertheless, in a study in Brazilian children, CRF was only positively associated with Math in girls [41], while in another study in Chilean children it was negatively related to reading/language arts and math scores in girls [42].…”

The relationship between physical activity (PA), cardiorespiratory fitness (CRF) and academic achievement in young people is unclear. The aim of this study was to analyze the relationship between PA, CRF and academic achievement in 152 children according to sex (average age of 8.6 ± 0.3 years) in southern Spain. A tri-axial accelerometer was used to measure PA; the 20-m Shuttle Run Test was performed to assess the CRF; and to know the academic achievement, the official school records were considered. The results showed a weak correlation between moderate PA and moderate-to-vigorous PA (MVPA) with CRF in boys (all, 0.2 > r < 0.4; p < 0.05), whereas the vigorous PA showed a moderate and weak correlation with CRF (all, p < 0.05), in both boys (r = 0.537) and girls (r = 0.382), respectively. In addition, a weak inverse correlation between moderate PA and MVPA with academic achievement showed in girls (all, 0.2 > r < 0.4; p < 0.05). Finally, the CRF weakly correlated with academic achievement only in boys (all, 0.2 > r < 0.4; p < 0.05). Our study showed a relationship between PA and CRF in both sexes. Nonetheless, the PA was inversely related to academic achievement in girls, whereas the CRF was related to academic achievement in boys.

“…Students were asked whether they engaged in strenuous activity, equal to or more than three days a week (Yes = 1, No = 0). Strenuous activity was defined as sports, games, or dance that made them breathe hard, made their legs feel tired, or made them sweat [10]. …”

“…Since the establishment of recommendations for pediatric screen times [3], an increase in the number and volume of sedentary activities negatively impacting positive behaviors [9] and overall wellbeing [10] has been observed. These effects include less time for PA and sleep [9], poorer academic performance [11], and higher risk of obesity and becoming overweight [12].…”

Screen time is negatively associated with markers of health in western youth, but very little is known about these relationships in Chinese youth. Middle-school and high-school students (n = 2625) in Wuhan, China, completed questionnaires assessing demographics, health behaviors, and self-perceptions in spring/summer 2016. Linear and logistic regression analyses were conducted to determine whether, after adjustment for covariates, screen time was associated with body mass index (BMI), eating behaviors, average nightly hours of sleep, physical activity (PA), academic performance, and psychological states. Watching television on school days was negatively associated with academic performance, PA, anxiety, and life satisfaction. Television viewing on non-school days was positively associated with sleep duration. Playing electronic games was positively associated with snacking at night and less frequently eating breakfast, and negatively associated with sleep duration and self-esteem. Receiving electronic news and study materials on non-school days was negatively associated with PA, but on school days, was positively associated with anxiety. Using social networking sites was negatively associated with academic performance, but positively associated with BMI z-score, PA and anxiety. Screen time in adolescents is associated with unhealthy behaviors and undesirable psychological states that can contribute to poor quality of life.

“… yes; yes; no no Physical activity: Since strenuous PA is strongly [ 43 ] and independently associated with markers of cardiometabolic health [ 44 ], and can be more reliably assessed than light or moderate PA [ 45 ], we assessed only strenuous PA [ 45 ]. Strenuous activity was defined as sports, games, or dance that made respondents breathe hard, make their legs feel tired, or made them sweat [ 46 ]. Are you usually engaged in strenuous activity, equal to or more than three days a week?…”

This study aims to examine associations between body weight misperception and eating behaviors among Chinese adolescents. Students (N = 2641) from a middle school and a high school in Wuhan, China participated in a cross-sectional study in May 2016. A questionnaire based on the World Health Organization’s Global School-Based Student Health Survey was employed to assess responses. Self-reported data, including weight, height, body weight perception, and eating habits, were collected. Body Mass Index (BMI) for age z-score was calculated from self-reported height and weight using WHO AnthroPlus. We used descriptive, logistic regression analysis and a Kappa test to analyze the data using SPSS. Overall, 56.6% of participants did not correctly categorize their weight status; these were much more likely to be girls. Compared with the correctly-perceived group, those who underestimated their weight tended to report eating late at night, having dinners with family, and checking nutrition labels. In contrast, weight overestimating students were less likely to report eating late at night, having breakfasts with family, having dinners with family, and discussing nutrition topics over meals. Body weight misperception was associated with unhealthy eating behaviors among Chinese adolescents.
