Medical research: Health issues for former rugby players


今回、Madeleine Davies、Nigel Ardenたちの研究グループは、自己申告による質問票を使って、エリートラグビー選手だった男性259人の健康のさまざまな側面を評価し、一般集団の年齢標準化サンプルの場合と比較した。その結果分かったことは、50歳以上の元ラグビー選手が、英国縦断的高齢化調査(English Longitudinal Study of Aging; ELSA)の参加者5186人と比べて、骨粗鬆症や変形性関節症にかかり、関節置換手術、人工股関節や人工膝関節の置換手術を受ける可能性が高かったことだ。また、元ラグビー選手は、イングランド健康調査(Health Survey for England)の参加者2981人と比べて、運動性と疼痛/不快感について問題があることを報告する確率が2倍高いことも判明した。これに対して、元ラグビー選手が糖尿病を発症するリスクは有意に低く、この点については、一生の運動量が多いことの反映である可能性があるが、いずれのグループについても現在の運動に関するデータがないため確認できていない。


Former elite male rugby union players are at greater risk of suffering from osteoarthritis, joint replacement and osteoporosis compared to the rest of the population, according to a study in Scientific Reports this week.

Using self-reported questionnaires, Madeleine Davies, Nigel Arden and colleagues assessed aspects of health amongst 259 former elite, male rugby players, compared to an age-standardised sample from the general population. The authors found that compared to 5,186 participants from the English Longitudinal Study of Aging, rugby players aged 50 and above were more likely to suffer from osteoporosis, osteoarthritis, joint replacement, and site-specific joint replacement at the hip and knee. The authors also found that rugby players were twice as likely to report problems related to mobility and pain/ discomfort compared to 2,981 participants from the Health Survey for England. Rugby players had a significantly lower risk of diabetes compared to this group, which may reflect a higher level of lifetime physical activity, although this cannot be confirmed as data on current activity was not available in both groups.

The authors propose that the risk of osteoarthritis among elite rugby players warrants proactive education and management within this sporting population. Further research is needed to examine the application of these findings in modern rugby (the participants were from the amateur era and modern professional rugby has many differences, including player physique), for female participants, and for those participating at lower levels.
