Resumen Introducción: la dieta proinflamatoria contribuye a una mayor sintomatología en pacientes con osteoartritis de rodilla (OAR); sin embargo, en México parece no existir evidencia del papel inflamatorio dietético, pues es un país con alta prevalencia de sobrepeso y obesidad con inclinación hacia una dieta occidental. Objetivo: analizar la relación del índice inflamatorio dietético (IID) con la sintomatología de OAR en pacientes mexicanos. Material y métodos: estudio transversal, analítico en 100 pacientes de 40 a 70 años. Se evaluó el dolor, la rigidez y la funcionalidad con el Western Ontario and McMaster Universities Arthritis Index (WOMAC) y el IID se calculó a partir del cuestionario semicuantitativo de frecuencia de consumo de alimentos (CSFC). Para su análisis, se calculó regresión lineal. Resultados: el IID se asoció significativamente con dolor (p = 0.001, R² = 0.118), funcionalidad (p = 0.003, R² = 0.087) y puntaje del WOMAC (p = 0.001, R² = 0.099). En el segundo modelo de regresión lineal con la variable dependiente funcionalidad, se ajustó la circunferencia de cintura (CC) y se obtuvo una R² = 0.144 y una mayor significación: p = 0.001. Conclusiones: el IID proinflamatorio se relacionó con un mayor dolor, una menor funcionalidad y un puntaje alto del WOMAC, por lo cual la dieta antiinflamatoria podría considerarse como un apoyo para el tratamiento del paciente con OAR.
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.
