Abstract

Background: The Northern Finland 1966 birth cohort (NFBC 1966) is an epidemiological study where the participants have been controlled since pregnancy both in field tests and using questionnaires. This study aimed to evaluate cross-sectionally the association of self-reported oral symptoms (dental caries and bleeding of gums) with sociodemographic and health behavior factors among the subjects.

Methods: Of the 11,541 original members of the cohort, 8,690 (75%) responded to the questionnaire on oral health (dental decay, gingival bleeding and self-estimated dental treatment need) and sociodemographic factors, general health and health behavior. Cross-tabulation and chi-squared tests as well as multiple logistic regression analysis were used to analyze the association between the outcome and explanatory variables.

Results: The study group was equally distributed between the genders. One third of the subjects reported having dental decay, one fourth gingival bleeding and a half a dental treatment need. As compared to women, men reported significantly more frequently symptoms (p < 0.05). Logistic regression analysis revealed low tooth brushing frequency increasing the odds most for all oral symptoms ((OR 1.57 (1.39-1.78) for dental decay, 1.94 (1.68-2.24) for gingival bleeding and 1.42 (1.26-1.61) for dental treatment need). Frequent smoking was associated with dental decay (OR 1.63 (1.44-1.84)) and treatment need OR (1.39 (1.23-1.56)), whereas poor general health (OR 1.71 (1.48-1.96)) and high BMI (OR 1.19 (1.03-1.36)) both were associated with gingival bleeding.

Conclusions: Males with single marital status, BMI over 25, poor general health and poor oral health behaviors are at risk for self-reported poor oral health and dental treatment need.
