Obesity and Oral Health‐Related Quality of Life: An Exploratory Analysis of Associated Factors
OBJECTIVES: This study assessed oral health-related quality of life in individuals with and without obesity, and investigated its association with socioeconomic-demographic characteristics, lifestyle habits, health conditions, and clinical care. METHODS: A cross-sectional study was conducted with 250 individuals (≥ 18 years) in Salvador-Brazil. Data were collected using structured questionnaires, anthropometric assessments, and clinical oral examinations. Oral health-related quality of life was measured using the Oral Health Impact Profile-14. Obesity was classified by waist circumference. Sequential blockwise multiple regression models were employed for data analysis. RESULTS: Impaired oral health-related quality of life was reported by 56.7% of the overall sample. Obese individuals showed worse Oral Health Impact Profile-14 scores compared to non-obese individuals, with greater impairment in physical pain, and physical, psychological, and social disability domains. In final multivariate models, female sex, cardiovascular disease, and the decayed, missing, and filled teeth index were associated with impaired oral health-related quality of life among obese individuals. CONCLUSIONS: Obese individuals showed lower oral health-related quality of life scores than non-obese individuals, linked to poor oral health. Female sex, cardiovascular disease, and high decayed, missing, and filled teeth index scores emerged as significant factors associated with worse outcomes.
