Note s: *P < 0.05, **P < 0.01, model 1 was not adjusted by any variables, model 2 was adjusted by age, gender, residential area, any siblings, perceived family income, academic performance and parent’s educational level. ACC, anterior cingulate gyrus; FFG, fusiform gyrus; PMPU, problematic mobile phone use; R, right.
