The association of milk consumption with the occurrence of symptomatic knee osteoarthritis.
OBJECTIVE
To evaluate the association of nutritional factors with symptomatic knee OA.


METHODS
This cross-sectional study was performed face-to-face using a structured interview. Individuals who had a diagnosis of symptomatic knee OA and were aged 50 years or over were included in this study. The frequency of consumption of dairy products, meat/poultry, fish, cereals, vegetables, tea and coffee were also determined. The diagnosis of knee OA was made clinically or clinically and radiologically according to the ACR criteria for knee OA.


RESULTS
A total of 655 subjects was interviewed. The frequency of symptomatic knee OA was significantly lower in daily milk consumers (p < 0.05). Tea consumption was also inversely associated with symptomatic knee OA (p < 0.05), although other nutritional elements showed no significant relationship with OA.


CONCLUSIONS
Milk consumption may have beneficial effects on symptomatic knee OA.
