BACKGROUND Sports participants are faced with the decision to continue or cease play when injured. The implications of playing sport while injured on joint health and health-related quality of life (HRQoL) has not been investigated. The purpose of this study was to investigate the relationship between having played sport while injured and HRQoL, osteoarthritis, and persistent joint pain; and compare findings in elite and recreational cricketers. METHODS The Cricket Health and Wellbeing Study cohort was used for this study. Inclusion criteria were: age ≥ 18 years, played ≥1 cricket season. Questionnaire data collected included a history of playing sport injured, SF-8 (physical (PCS) and mental (MCS) component scores), physician-diagnosed osteoarthritis, and persistent joint pain (most days of the last month). Multivariable linear regressions and logistic regressions were performed. Continuous covariates were handled using fractional polynomials. Models were adjusted for age, sex, cricket-seasons played, playing status, joint injury, and orthopaedic surgery. All participants (n = 2233) were included in HRQoL analyses, only participants aged ≥30 years (n = 2071) were included in osteoarthritis/pain analyses. RESULTS Of the 2233 current and former cricketers (mean age: 51.7 SD 14.7, played 30 IQR 24 cricket seasons, 60% were current cricketers, 62% played recreationally; median PCS: 51.4 IQR 9.0; MCS: 54.3 IQR 8.6) 1719 (77%) had played sport while injured. People who had played sport injured reported worse adjusted PCS (Effect(95% CI): - 1.78(- 2.62, - 0.93) and MCS (- 1.40(- 2.25, - 0.54), had greater odds of osteoarthritis (adjusted OR(95% CI): 1.86(1.39, 2.51) and persistent joint pain (2.34(1.85, 2.96)), compared to people who had not played sport injured. Similar relationships were observed regarding PCS, osteoarthritis and pain in elite and recreational subgroups. Playing injured was only related to worse MCS scores for elite cricketers (- 2.07(- 3.52, - 0.63)); no relationship was observed in recreational cricketers (- 0.70(- 1.79, 0.39)). CONCLUSION Cricketers that had played sport injured had impaired HRQoL, increased odds of osteoarthritis and persistent joint pain, compared to those who had not played sport injured. Playing sport injured was only related to impaired mental-components of HRQoL in elite cricketers. The long-term impact of playing while injured on musculoskeletal health, should be considered when advising athletes on their ability to compete following injury.

运动受伤与骨关节炎、关节疼痛和健康相关生活质量较差有关：一项横断面研究。


背景技术体育参与者在受伤时面临着继续或停止比赛的决定。受伤时进行运动对关节健康和健康相关生活质量 (HRQoL) 的影响尚未得到调查。本研究的目的是调查受伤时进行运动与 HRQoL、骨关节炎和持续性关节疼痛之间的关系；并比较精英板球运动员和休闲板球运动员的研究结果。方法 本研究使用板球健康与福祉研究队列。纳入标准为：年龄≥18岁，打过≥1个板球赛季。收集的问卷数据包括运动受伤史、SF-8（身体 (PCS) 和精神 (MCS) 成分评分）、医生诊断的骨关节炎和持续性关节疼痛（上个月的大部分时间）。进行多变量线性回归和逻辑回归。使用分数多项式处理连续协变量。模型根据年龄、性别、板球赛季、比赛状态、关节损伤和骨科手术进行了调整。所有参与者 (n = 2233) 均纳入 HRQoL 分析，仅年龄 ≥ 30 岁的参与者 (n = 2071) 纳入骨关节炎/疼痛分析。结果 在 2233 名现任和前任板球运动员中（平均年龄：51.7 SD 14.7，参加过 30 IQR 24 个板球赛季，60% 是现任板球运动员，62% 从事休闲活动；PCS 中位数：51.4 IQR 9.0；MCS：54.3 IQR 8.6）1719（77 %) 受伤时参加过运动。参加过运动受伤的人报告调整后的 PCS 更差（效果（95% CI）：- 1.78（- 2.62，- 0.93）和 MCS（- 1.40（- 2.25，- 0.54）），骨关节炎的几率更大（调整后 OR（95） % CI）：与没有参加运动受伤的人相比，1.86（1.39，2.51）和持续性关节疼痛（2.34（1.85，2.96））。 在精英亚群和娱乐亚群中，PCS、骨关节炎和疼痛也观察到类似的关系。对于精英板球运动员来说，受伤只与较差的 MCS 分数相关（- 2.07（- 3.52，- 0.63））；在休闲板球运动员中没有观察到任何关系（- 0.70（- 1.79，0.39））。结论 与没有参加运动受伤的板球运动员相比，参加过运动受伤的板球运动员的 HRQoL 受损，骨关节炎和持续性关节疼痛的几率增加。参加运动受伤仅与精英板球运动员的 HRQoL 心理成分受损有关。在就运动员受伤后的比赛能力提供建议时，应考虑受伤时比赛对肌肉骨骼健康的长期影响。
