Abstract

Background/purpose: Dyslipidemia and a high fat diet may increase the predisposition for accumulating body fat in patients with oral lichen planus (OLP). This study aimed to investigate the risk factors obesity, dietary patterns, and lipid metabolism.

Materials and methods: A population-based case-control study was conducted between September 2020 and October 2021, recruiting 275 pairs of OLP cases and controls. Information on lipid profiles, diet frequency and waist circumference were gathered. Principal component and factor analysis were used to analyze the semi-quantitative dietary frequency survey data of patients to extract specific dietary patterns.

Results: Univariate analysis showed that total cholesterol, triglycerides, and low-density lipoprotein were significantly higher in the OLP group than the control and other oral mucosal disease groups (P < 0.05, P < 0.001, and P < 0.001, respectively). Compared with the baseline group, obese and overweight patients were more common in the OLP group. Dyslipidemia was more common in the OLP group (68%) compared to the healthy mucosa group (32%; P < 0.001, OR = 4.52, 95% CI = 2.49-8.18). Four dietary patterns were described among the subjects. The traditional prone animal food pattern (OR: 24.81, 95% CI: 6.05-101.71, P < 0.001) and animal food pattern (OR: 28.77, 95% CI: 8.10-102.15, P = 0.001) were associated with an increased risk of OLP.

Conclusion: The results indicated that a high-fat diet, dyslipidemia and obesity were strongly linked to disease progression in OLP. A diet high in processed food and fat could increase the risk of OLP.

Keywords: Animal food pattern; Dietary patterns; Dyslipidemia; Obesity; Oral lichen planus.
