Background:
Proinflammatory diet contributes to greater symptomatology in patients with knee osteoarthritis (KOA); however, in Mexico there seems to be no evidence of the dietary inflammatory role, being a country with high prevalence of overweight and obesity with an inclination towards a Western diet.
Objective:
To analyze the relationship between dietary inflammatory index (DII) and KOA symptomatology in Mexican patients.
Material And Methods:
Analytical cross-sectional study in 100 patients aged 40 to 70 years. Pain, stiffness, and functionality were evaluated with the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and the DII was calculated from the semi-quantitative food consumption frequency questionnaire (QFCFQ). For its analysis, linear regression was calculated.
Results:
DII was significantly associated with pain (p = 0.001, R² = 0.118), functionality (p = 0.003, R² = 0.087) and WOMAC score (p = 0.001, R² = 0.099). In the second linear regression model with the dependent variable functionality, waist circumference (WC) was adjusted obtaining an R² = 0.144 and higher significance p = 0.001.
Conclusions:
Proinflammatory DII was related to greater pain, lower functionality and a high WOMAC score, which is why the anti-inflammatory diet could be considered as a support for the treatment of the patient with KOA.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
