The World Health Organization reports that the number of obese adolescents worldwide will continue to rise in the next decade. And it is commonly used internationally to judge the degree of obesity, wasting and health of the human body. Thus, high BMI impairs inhibitory control and thus has a negative impact on academic performance, which can be buffered by social support.īody mass index (BMI), as an important indicator of an individual’s physical quality, is used to measure the total amount of body fat. Support from teachers, parents, and peers can ameliorate the negative effects of BMI on academic performance, with teacher support and parental support also ameliorating the negative effects of BMI on inhibitory control. The results showed that students with high BMI had poorer academic performance, and inhibitory control partially mediated the effect between BMI and academic performance, with the inhibitory control mediated effect accounting for 36.68% of the total effect.

By using height and weight measurements, the classic stroop task, and the social support scale, 264 secondary school students in Shanxi Province, China, were surveyed and their academic performance was collected. In addition, it was verified that the strength of this mechanism depends on the teacher, parent, and peer support received by secondary school students.
