Abstract and Introduction
Background: A parental/family history of poor oral health may influence the oral-health-related quality of life (OHRQOL) of adults.
Objectives: To determine whether the oral health of mothers of young children can predict the OHRQOL of those same children when they reach adulthood.
Methods: Oral examination and interview data from the Dunedin Study's age-32 assessment, as well as maternal self-rated oral health data from the age-5 assessment were used. The main outcome measure was study members' short-form Oral Health Impact Profile (OHIP-14) at age 32. Analyses involved 827 individuals (81.5% of the surviving cohort) dentally examined at both ages, who also completed the OHIP-14 questionnaire at age 32, and whose mothers were interviewed at the age-5 assessment.
Results: There was a consistent gradient of relative risk across the categories of maternal self-rated oral health status at the age-5 assessment for having one or more impacts in the overall OHIP-14 scale, whereby risk was greatest among the study members whose mothers rated their oral health as "poor/edentulous", and lowest among those with an "excellent/fairly good" rating. In addition, there was a gradient in the age-32 mean OHIP-14 score, and in the mean number of OHIP-14 impacts at age 32 across the categories of maternal self-rated oral health status. The higher risk of having one or more impacts in the psychological discomfort subscale, when mother rated her oral health as "poor/edentulous", was statistically significant.
Conclusions: These data suggest that maternal self-rated oral health when a child is young has a bearing on that child's OHRQOL almost three decades later. The adult offspring of mothers with poor self-rated oral health had poorer OHRQOL outcomes, particularly in the psychological discomfort subscale.
Oral-health-related quality of life (OHRQOL) measures examine the extent to which oral disease affects an individual's well-being. They aim to determine the subjective functional and psycho-social impacts of oral disease, and complement traditional objective clinical indicators to facilitate a more holistic approach to oral health. Research has indicated a range of influences on oral-health-related quality of life (OHRQOL). These include direct oral health factors such as untreated caries and missing teeth,[2–5] periodontal disease,[2,6,7] malocclusion, and xerostomia.[8,9] In addition, age, sex,[10,11] socio-economic status,[2,12,13] socio-cultural factors,[3,14,15] psychosocial factors,[16,17] dental care services attendance pattern,[12,13,18] and dental anxiety[19,20] can all impact on OHRQOL.
A potential impact on OHRQOL that remains unexamined is the effect of parental/family history of poor oral health. It is likely that intergenerational processes link maternal oral health (and maternal oral health beliefs, attitudes and behaviours) to oral health and disease risk in offspring.[21–28] If maternal oral health is associated with offspring oral health, and oral health is associated with OHRQOL, then it is reasonable to believe that maternal oral health is also associated with offspring OHRQOL through this pathway. However, is it possible that maternal oral health also exerts an influence on her offspring's OHRQOL via other mechanisms?
Population oral health and population OHRQOL, while inextricably linked, are not the same. While it can be debated whether the primary objective of public health measures should be the improvement of oral health or OHRQOL, it is likely that the burden of impaired OHRQOL is substantial. For this reason, putative predisposing factors for poor OHRQOL require careful and comprehensive examination. This will allow the identification of those who are at greatest risk of suffering poor OHRQOL due to poor oral health, but also independently of clinical oral health factors. Thus, the current study sought to determine whether the oral health of mothers of young children can predict the OHRQOL of those same children when they reach adulthood. It tested the hypothesis that mothers' self-rated oral health when children are young can predict her offspring's OHRQOL many years later.
