Parenting stress as a mediator in the oral health of children and adolescents: A stress process model.

OBJECTIVES

We tested hypotheses regarding socioeconomic status (SES) disparities in oral health amongst children and adolescents and the extent to which such SES disparities may be mediated by parenting stress.

METHODS

We analysed data from the 2011/2012 US National Survey of Children's Health for ages 6-11 years (n = 21 596) and 12-17 years (n = 23 584). Our models estimated associations between SES indicators (family income and parental education) and parenting stress with two oral health outcomes: parent-reported child oral health and preventive dental visits.

RESULTS

For both age groups, SES was positively associated with both oral health outcomes. Parenting stress mediated the relationship between SES and child oral health, not preventive dental visits-such that lower SES was associated with worse oral health via higher parenting stress. Amongst children, the indirect effect of parenting stress was observed for parental education and family income, whilst amongst adolescents, no indirect effect of parenting stress was observed.

CONCLUSION

Parenting stress was an important determinant of children's oral health and partially explained the SES-related oral health disparities in children. Future research is needed to explore the causal pathways in this association.
