The study investigated the association of cholesterol levels with pupils who had been suspended or expelled from school. The study included 4,852 children aged 6–16 years.

The study found showed that children between 6 and 16 years of age whose cholesterol concentration was below 3.77 mmol/L (145 mg/dL) were 73% more likely to have been suspended or expelled from schools than children with higher cholesterol levels.

Zhang concluded that low total cholesterol is associated with school suspension or expulsion and that low cholesterol may be a risk factor for aggression.
