Longitudinal relationship from good pounds switch to instructional performance in children
Although there is a growing consensus about the positive relationship between prevention of overweight/obesity and academic performance in children, relevant studies targeting the relationship between underweight http://datingranking.net/tr/iraniansinglesconnection-inceleme and academic performance are scarce. This study aimed to examine the longitudinal relationship of favorable weight change to academic performance in schoolchildren. We analyzed 2-year longitudinal data derived from 197 seventh-grade children aged 12–13 years. Academic performance was assessed using the total grade points of five academic subjects. Body mass index (BMI) was calculated as body weight (kg)/height (m 2 ). A significant interaction effect of baseline BMI and BMI changes over 2 years (B = ?0.10, SE B = 0.03, ? = ?0.40, t = –3.37, p < 0.001) was noted after controlling for confounders such as socioeconomic status, afterschool learning duration, screen time, exercise habits, and cardiorespiratory fitness. When the centered baseline BMI was outside the interval [?2.49, 3.21], the slope of the change in BMI was significant (p < 0.05). Simple slope analyses revealed a positive relationship of weight gain when baseline BMI = mean ? 1 SD (B = 0.40, SE B = 0.18, ? = 0.31, t = 2.20, p = 0.03) and weight loss when baseline BMI = mean + 1 SD (B = ?0.26, SE B = 0.13, ? = ?0.20, t = ?1.97, p = 0.05) to total grade points of five school subjects. A split-group validation was performed and robust results of original analyses were detected (i.e., significant interaction effect of baseline BMI and BMI changes over 2 years (group A: B = ?0.11, SE B = 0.05, ? = ?0.47, t = ?2.39, p = 0.02; group B: B = ?0.14, SE B = 0.05, ? = ?0.47, t = ?2.78, p = 0.007). Favorable changes in weight status, i.e., weight loss in children with overweight/obesity and weight gain in children with mild underweight/underweight, have a positive influence on academic performance in children independent of socioeconomic factors, learning habits, screen time, exercise habits, and cardiorespiratory fitness.
