Oral Hygiene Status in a General Population of Iran, ۲۰۱۱: A Key Lifestyle Marker in Relation to Common Risk Factors of Non-Communicable Diseases

Background To estimate Oral Hygiene (OH) status in the Iranian population in ۲۰۱۱, and to determine the influence of socio-economic characteristics on OH, and its interrelation with common risk factors of Non-Communicable Diseases (NCDs).   Methods Data including a total of ۱۲,۱۰۵ individuals aged ۶-۷۰ years were obtained from the sixth round of the surveys of NCDs risk factors in Iran. OH was recorded through a structured questionnaire measuring daily frequencies of tooth brushing and dental flossing. Descriptive analyses were performed on demographic characteristics in the complex sample survey setting. We also employed weighted binary logistic regression to compute Odds Ratio (OR) as a measure of association between the response and explanatory factors. Furthermore, to construct an asset index, we utilized Principal Component Analysis (PCA).   Results The percentage with minimum recommended daily OH practices was ۳.۷% among men and ۷.۷% among women  (OR= ۲.۳; P< ۰.۰۰۱). Urban citizens were more likely to have their teeth cleaned compared to rural people (OR= ۲.۸; P< ۰.۰۰۱). For both genders, a relatively better condition was observed in the ۲۵–۳۴ age group (male: ۵.۶%; female: ۱۰.۳%). In addition, OH status improved significantly by increase in both level of education (P< ۰.۰۰۱) and economic status (P< ۰.۰۰۱). There were also apparent associations between self-care practices and specific behavioral risk factors, though the correlation with dietary habits and tobacco use could be largely explained by socio-economic factors.   Conclusion OH situation in Iran calls for urgent need to assign proper interventions and strategies toward raising public awareness and reducing disparities in access to health facilities.
