This study examines the impact of the deviation between parents'
educational expectations and children's parent--child educational
expectations on children's health based on the data from Chinese family
tracking surveys conducted in 2018 and 2020. We found that when parents'
educational expectations are higher than their children's educational
expectations, they have a negative impact on children's health status.
According to the influence mechanism, the higher the parents'
expectations of education are, the greater children's remedial behavior
will be, the less leisure time will be, which will adversely affect
children's health. Furthermore, we found that a good parent-child
relationship moderated the negative impact of the deviation in
parent-child educational expectations on children's health. Therefore,
in order to ensure the healthy development of children, it is necessary
to resolve the adverse effects of the deviation in parent--child
educational expectations by arranging tutoring and leisure time
rationally and establishing a good parent-child relationship.
