Abstract

Background: The oral health-related quality of life (OHRQoL) assessment evaluated the impact of individual’s oral health on the patient's physical and psychosocial status. We evaluated the association between subjective OHRQoL, measured with the Oral Health Impact Profile-14 (OHIP-14) questionnaire, and unfavorable body mass index (BMI) (i.e., too high or too low) in a large population-based study on older adults from Southern Italy. Moreover, we assessed which of the seven OHIP-14 domains was most strongly associated with an unfavorable BMI. Methods: We used data on a subpopulation of the Salus in Apulia Study, including 216 older adults. BMI <18.4 kg/m2 and >30 kg/m2 were classified as unfavorable, values between 18.5 and 30 kg/m2 were classified as ideal. Results: Higher OHIP-14 total score increased the risk to have an unfavorable BMI [odds ratio (OR):1.08, 95% confidence interval (CI):1.01-1.15]. In the model adjusted for age, sex, education, hypertension, carbohydrate consumption, and alcohol consumption, this finding was confirmed with higher OHIP-14 total score increasing the risk to have an unfavorable BMI (OR:1.10, 95% CI:1.01-1.22), and higher age linked to a decreased risk to have an unfavorable BMI (OR:0.89, 95% CI:0.82-0.97). In a random forest regression model, the most important predictive domains/sub-scales of OHIP-14 in mean decrease Gini for unfavorable BMI were, in order of decreasing importance, physical pain, functional limitation, psychological discomfort, physical disability, social disability, psychological disability, and handicap. Conclusions: In older age, negative OHRQoL, particularly linked to the physical pain domain, increased the risk of underweight or overweight and obesity.
