Aim To prospectively investigate the associations between major dietary patterns and incidence of periodontitis. Methods We included 34,940 men from the Health Professionals Follow‐Up Study, free of periodontal disease and major illnesses at baseline. Detailed medical and dental history was collected through biennial mailed questionnaires, and dietary information was provided through quadrennial food frequency questionnaires. Using principal component analysis, we identified two major dietary patterns (“prudent” and “Western”). We used Cox proportional hazard models to examine the associations between the two dietary patterns and self‐reported incidence of periodontitis over a 24‐year follow‐up period. We investigated each pattern separately. Results There was no overall association between Western or prudent dietary patterns and periodontitis. Among obese, however, the Western dietary pattern was significantly associated with incident periodontitis. The hazard ratio for those in the highest quintile of Western diet versus those in the lowest (reference) was 1.83 (95% confidence interval: 1.21–2.76). Conclusions There was no overall association between Western or prudent dietary patterns and periodontitis; however, in subgroups analysis, the Western diet was significantly associated with higher periodontitis risk only among obese men, a finding that requires replication and biological explication.
