Résumé :
Background: Oral health is integral to health and well-being, yet periodontal disease, or inflammation of the tooth-supporting structures i.e. gums and bone, remains one of the most prevalent global health issues that disproportionately affect individuals of lower socioeconomic status (SES). Objectives: To investigate the association of periodontal disease incidence with (i) neighbourhood-level SES and (ii) school environment in Quebec. Methods: Longitudinal data are retrieved from the QUALITY cohort of children aged 8-10y, 11-13y, and 15-18y (n=300). Generalized linear models are used to independently examine the association of neighbourhood-level SES operationalized as the neighbourhood deprivation index with periodontal disease measures (gingival index, plaque index, gum bleeding, and pocketing) at each wave. Based on a series of previous analysis, three distinct types of school environment were identified depending on food environment, healthy eating and oral health-promoting programs. Models are adjusted for confounders and stratified by child sex at birth. Results: Initial results show that children in neighbourhoods with higher deprivation indices have higher periodontal disease incidence across the three study waves. Schools that are characterized by a low SES neighbourhood, unfavourable food environment, and no healthy eating or oral health promotion programs are also anticipated to be associated with a higher incidence of periodontal disease in all three waves. Conclusion: The findings of this study are anticipated to highlight the impact of socioeconomic disadvantage on oral health trajectories over the life course and inform policies for oral disease prevention in schools.
