Does a social/behavioural gradient in dental health exist among adults? A cross-sectional study

Abstract

Objective: To explore the potential presence of a social/behavioural gradient in dental health among Italian adults using a cross-sectional study. Methods: Caries indices were recorded among 480 subjects (52.9% men, 47.1% women) who also completed a structured self-administered social and behavioural questionnaire. A social/behavioural gradient was generated as the sum of the worst circumstances recorded on the questionnaire (cariogenic diet, smoking, lowest occupational profile, brushing teeth < 0.01, Z = −4.31 p < 0.01). DMFT was statistically significantly associated with gender and with social and behavioural variables. FS-T was higher in women (p = 0.03) and was linked to smoking (p < 0.01). Conclusions: The proposed social/behavioural gradient demonstrated how subjects reporting the worst circumstances on the questionnaire exhibited the worst dental health. The use of the gradient demonstrates that health promotion and prevention cannot be compartmentalized.
