The BBC reported on a recent survey by the British Heart Foundation which found that most parents in the UK vastly overestimate the amount of exercise their children are getting. While 72% of parents believe that their children are getting enough exercise, according to the survey, only one in ten children actually get the recommended amount of exercise per day. As more children begin to suffer the ill effects of not exercising and because obesity in children is on the rise, there is added urgency to understand how weight impacts the lives of children.
A recent study by Clark, Slate, and Viglietti (2009), found that children who were severely overweight had significantly worse marks in all subjects than students who were not obese. The same was seen with standardized test scores and was found even when controlling for economic status or student conduct. However, the results were only found among white students; weight was not significantly correlated with grades for students in other ethnic categories. The authors caution that much more research should be done as their sample was somewhat limited and that people should be careful of studies looking at weight categories because many children go through growth-spurts at different times. Furthermore, it is important to remember that their research only showed that weight and academic performance were correlated. It is impossible to say that obesity causes low grades when it could very well be the other way around or other factors may influence both grades and weight.
Regardless, the study is interesting because it highlights that the issue of obesity may be worrisome not just because of its ill effects on physical health. Children who are overweight might suffer from low self-esteem or become victims of bullying or social exclusion, all of which could impact their physical and mental health. There are still a number of questions that social psychologists could help answer: Why does obesity negatively correlate with academic success? Do teachers treat obese children differently than non-obese children? Or, are children who are suffering academically less likely to exercise and eat a proper diet?
