Correlation Between Oral Health and Body Mass Index among Nepalese Teachers

Background Health problems like high body weight and oral diseases have the same essential risk factors as the inflammatory nature of obesity and periodontal disease are widely recognized. Body Mass Index and oral health indices are correlated and may be a confounder of disease status. Objective To assess oral health status and Body Mass Index of school teachers of Kathmandu valley and to find the correlation between them. Method A cross sectional study with purposive sampling was done on 100 Nepalese teachers to assess Body Mass Index, Community Periodontal Index and Decayed Missing Filled Teeth index. Mann-Whitney U-test, crude and adjusted odds ratio were used to analyze the difference between periodontal status based on Community Periodontal Indexscores in relation to age, Body Mass Index, Decayed Missing Filled Teeth. Result The prevalence of periodontal disease according to Community Periodontal Index score was: bleeding on probing 14%, calculus 34%, pocket depth 4-5 mm 35%, pocket depth ≥ 6 mm 12%. The mean Decayed Missing Filled Teeth index was 4.41, and mean number of teeth present was 29.22. According to Body Mass Index score; 10% were underweight, 38% overweight and 2% obese. There were significant differences in age, Body Mass Index and number of teeth present between the control and periodontitis groups. Logistic regression analysis revealed that the risk of periodontal disease increased with age, and there is an increased risk of periodontitis by 39% for each 1 kg/m2 Body Mass Index increase. Conclusion There is increased risk of periodontitis with gain in Body Mass Index in teachers of Kathmandu valley.
