Periodontal disease severity is associated with micronutrient intake

Abstract

Background

This study aimed to examine if specific micronutrients were associated with periodontal disease using data from the United States National Health and Nutrition Examination Survey (NHANES) from 2011-2014.

Methods

Participants who were ≥ 30 years of age and received complete periodontal examinations were included. Regression analyses were performed to determine associations of variables of interest with periodontal disease.

Results

Data of 6,415 NHANES participants were included in the analysis. Multivariable analysis revealed that less intake of vitamin A (aOR = 1.784), vitamin B1 (aOR = 1.334), vitamin C (aOR = 1.401), vitamin E (aOR = 1.576), iron (aOR = 1.234), folate (aOR = 1.254), and phosphorus (aOR = 1.280) was associated with increased severity of periodontal disease. Compared with the highest level of vitamin D intake, the second highest level of vitamin D intake was associated with lower severity of periodontal disease (aOR = 0.727).

Conclusion

Insufficient intake of vitamin A, B1, C, and E, iron, folate, and phosphorus was significantly associated with severity of periodontal disease. Results of the present study suggest that the above micronutrients may be increased in the diet or taken as dietary supplements in order to reduce severity of periodontal disease.
