Background: The development of chronic periodontitis (CP) is a multifactorial process and variation in severity cannot be explained by just a few risk factors. The aims of this study were: 1) to explore the lifestyle and psychosocial factors of CP patients and 2) to estimate the proportion of total CP cases attributable to one or more risk factors considered. Methods: A case‐control study of 250 cases of CP patients and 250 controls were matched by age (within 3 years) and gender. Complete dental examinations were performed based on the clinical criteria for CP for both groups. Structured questionnaires were conducted to collect lifestyle and psychosocial factors. Multivariate logistic regression was applied to assess the association between risk factors and chronic periodontitis. Results: Conditional multivariable logistic regression analysis showed that toothbrushing frequency (odds ratio [OR]: 5.77, if rarely; OR: 3.50, if once a day), mental illness (OR: 5.32, if Chinese Health Questionnaire scores were ≥6), and smoking (OR: 3.93, if pack years smoked was >21) are significantly and independently associated with chronic periodontitis. In addition, all these variables reected a dose‐response effect ( P trend = <0.001, 0.004, and 0.005, respectively). Conclusions: For Taiwanese adults, 36.10% of CP cases were presumably attributable to toothbrushing frequency, mental illness, and smoking. These three factors should be the first priorities in establishing a preventive program to improve the periodontal health status. J Periodontol 2003;74:1169‐1175 .
