Association between periodontitis and metabolic syndrome in the Hamburg City Health Study.

The use of the more current definitions for MetS and CP confirmed previous observations of an age- and sex-adjusted association between severe CP and MetS. Smoking, high-energy intake, and low physical activity were identified as important lifestyle-related confounders. Abdominal obesity, as indicated by elevated waist circumference, was determined as the most important component of MetS in relationship to CP.
