Abstract
OBJECTIVES
Recurrent aphthous stomatitis (RAS) is one of the most prevalent oral inflammatory ulcerative lesions. The aim of this large population base study was estimated lifetime prevalence of RAS and its related factors among the Northern Iranian population.
MATERIALS AND METHODS
This study was conducted on 10,520 participants aged 35-70 years based on the PERSIAN Guilan Cohort Study (PGCS). Prevalence proportions and multivariate logistic regression models were constructed for lifetime RAS prevalence using the SPSS software. Data on potential correlates of RAS including demographic profiles, lifestyle habits, and self-reported past medical histories were obtained.
RESULTS
The lifetime prevalence of RAS was 8.3%. Multivariate logistic models showed that urbanization (adjusted odds ratio (AOR) = 1.2) and having a history of systemic disease, including rheumatic disease (AOR = 2.1), genital aphthous disease (AOR = 11.7), depression (AOR = 1.3), chronic headaches (AOR = 1.8), diabetes mellitus (AOR = 1.6), and epilepsy (AOR = 2), were independent predictors of RAS. In addition, smokers (AOR = 0.5) and individuals older than 50 years of age (AOR = 0.8) were less likely to have a history of RAS. The lifetime prevalence of RAS among the Northern Iranian population was relatively low.
CONCLUSIONS
It seems that predisposing factors, such as younger age, urbanization, and systemic disease, including rheumatic disease, genital aphthous disease, depression, chronic headaches, diabetes mellitus, epilepsy, and not smoking, could contribute to RAS prevalence.
