Diet Practices, Body Mass Index, and Oral Health-Related Quality of Life in Adults with Periodontitis- A Case-Control Study.

Objectives: To assess and compare dietpractices, body mass index (BMI), and oral health-related quality of life (OHRQoL) in adults with and without periodontitis.Methods:Demographics, health-related behaviors, BMI, dental and periodontal parameters, diet practices, and Oral Health Impact Profile-14 (OHIP-14) were collected from 62periodontitis patients and 100 controls without periodontitis.Results:Havingperiodontitis was positively associated with male sex (p=0.004), older age (p<0.001), smoking pack-years (p = 0.006), weight (p = 0.008), BMI (p = 0.003), number of meals per day (p<0.001) and had a negative associationwithdecayed teeth (p = 0.013), alcohol (p = 0.006), and sweets (p = 0.007) consumption.Periodontitis patients were more likely to avoid carbonated beverages (p = 0.028), hot (p = 0.003), and cold drinks (p = 0.013), cold (p = 0.028), hardtextured (p = 0.002), and fibrous foods (p = 0.02) thanthe controls, and exhibited higher global OHIP-14 (p<0.001) andmost domain scores. Age (p<0.001), BMI (p =0.045), number of meals per day (p = 0.024), and global OHIP-14 score (p<0.001) remained positivelyassociated with periodontitis in the multivariate analysis. Conclusions:Periodontitis patients exhibitedhigher BMI and altered dietpracticesand OHRQoL as compared to controls. Assessment of diet practices, BMI,and OHRQoLshould bepart of periodontal work-up. Dentists and dietitians shouldcollaborate to design strategies to addressthese challenges.
