ABSTRACT
OBJECTIVES:
To assess the association of whole grain consumption with the risk of incident knee OA. MATERIAL ANDMETHODS:
We followed 2846 participants in the Osteoarthritis Initiative ages 45-79 years. Participants were free from radiographic knee OA (Kellgren-Lawrence grade <2) in at least one knee at baseline. Dietary data from baseline were obtained using the Block Brief Food Frequency Questionnaire. We defined radiographic knee OA incidence as a Kellgren-Lawrence grade ≥2 during the subsequent 96 months. Cox proportional hazards models were used to assess the association between whole grain food intake and the risk of incident knee OA.RESULTS:
During the 96 month follow-up, 518 participants (691 knees) developed incident radiographic knee OA. Higher total whole grain consumption was significantly associated with a lower knee OA risk [hazard ratio (HR)quartile 4vs1 = 0.66 (95% CI 0.52, 0.84), P for trend < 0.01] after adjusting for demographic and socio-economic factors, clinical factors and other dietary factors related to OA. Consistently, a significant inverse association of dark bread consumption with knee OA risk was observed [HRquartile 4vs1 = 0.68 (95% CI 0.53, 0.87), P for trend < 0.01). In addition, we observed a significant inverse association between higher cereal fibre intake and reduced knee OA risk [HRquartile 4vs1 = 0.61 (95% CI 0.46, 0.81), P for trend < 0.01).CONCLUSIONS:
Our findings revealed a significant inverse association of whole grain consumption with knee OA risk. These findings provide evidence that eating a diet rich in whole grains may be a potential nutritional strategy to prevent knee OA.Palavras-chave
