    Milk consumption and progression of medial tibiofemoral knee osteoarthritis: Data from the Osteoarthritis Initiative

    ABSTRACT
    Objectives: Milk consumption has long been recognized for its important role in bone health, but its role in the progression of knee osteoarthritis (OA) is unclear. We examine the prospective association of milk consumption with radiographic progression of knee OA.

    Methods: In the Osteoarthritis Initiative, 2,148 participants (3,064 knees) with radiographic knee OA and having dietary data at baseline were followed up to 12, 24, 36 and 48 months. The milk consumption was assessed with a Block Brief Food Frequency Questionnaire completed at baseline. To evaluate progression of OA, we used quantitative joint space width (JSW) between the medial femur and tibia of the knee based on plain radiographs. The multivariate linear models for repeated measures were used to test the independent association between milk intake and the decrease in JSW over time, while adjusting for baseline disease severity, body mass index, dietary factors and other potential confounders.

    Results: We observed a significant dose-response relationship between baseline milk intake and adjusted mean decrease of JSW in women (p trend=0.014). With increasing levels of milk intake (none, ≤3, 4-6, and ≥7 glasses/week), the mean decreases of JSW were 0.38mm, 0.29mm, 0.29mm and 0.26mm respectively. In men, we observed no significant association between milk consumption and the decreases of JSW.

    Conclusion: Our results suggest that frequent milk consumption may be associated with reduced OA progression in women. Replication of these novel findings in other prospective studies demonstrating the increase in milk consumption leads to delay in knee OA progression are needed. © 2014 American College of Rheumatology.

    "while adjusting for baseline disease severity, body mass index" at the start of the study ...
    Wonder if the milk drinkers weighed less at the END of the study ?

    If you didn't drink and eat dairy products in the first place, you'd likely be much less heavy thereby limiting the onset of the osteoarthritis in the first place. Calcium can be sourced from plants which is where the great apes get theirs from, without the baggage of saturated fats. I'd be interested to see if the great apes get knee OA.

    @Graham - It's harder to get the calcium from non-dairy sources.

    Yet people living in countries where there is rare dairy consumption manage just fine.
