More Arthroplasty for Hip Osteoarthritis With Dairy

Increased consumption of dairy products is associated with increased risk of total hip arthroplasty for osteoarthritis in men, a new study found. No significant association was observed for women.

Researchers in Australia evaluated data in the Melbourne Collaborative Cohort Study in an analysis published online May 15 in The Journal of Rheumatology.

Led by Sultana Monira Hussain, PhD, of Monash University in Australia, the investigators had the primary goals of assessing the impact of dairy consumption on total hip arthroplasty for osteoarthritis in general and exploring potential differences between men and women.

An estimated 1 in 4 persons will have symptomatic hip osteoarthritis in their lifetime. Given the burden of hip osteoarthritis for both patients and society, identifying modifiable risk factors like diet may help reduce the incidence and prevalence of hip osteoarthritis in the population.

Prior research suggested that small changes in bone geometry are involved in the development of hip osteoarthritis. Although dairy products are an important source of dietary calcium and are needed to maintain bone health, dairy consumption may have adverse effects. For example, higher milk consumption is hypothesized to affect hip bone geometry by reducing bone turnover and resorption.

To date, no known study has evaluated the relationship between dairy product consumption and risk of total hip arthroplasty for osteoarthritis.

The study

This was a prospective cohort study of 41,514 participants, aged 27 to 75 years, recruited as part of the Melbourne Collaborative Cohort Study between 1990 and 1994. Dietary data were collected at baseline with a 121-item food frequency questionnaire. The 12 dairy-related foods items were cottage cheese, ricotta cheese, feta cheese, low fat cheese, low cholesterol cheese, hard grating cheese, cream cheese, cheddar or similar cheese, ice cream, custard, cream or sour cream, yogurt, and milk. Other data included demographic, lifestyle, and anthropometric factors and circulating 25-hydroxy vitamin D.

Incidence of total hip arthroplasty for osteoarthritis was assessed between 2001 and 2013 by linking participants in the cohort to the Australian Orthopaedic Association National Joint Replacement Registry. An incident case was defined as the first recorded primary total joint arthroplasty being a total hip arthroplasty for osteoarthritis.
