This cross-sectional study examined racial/ethnic differences in meeting the 2008 United States Department of Health and Human Services Physical Activity Guidelines aerobic component (≥150 moderate-to-vigorous minutes/week in bouts of ≥10 minutes) among persons with or at risk of radiographic knee osteoarthritis (RKOA).
We evaluated African American versus white differences in guideline attainment using multiple logistic regression, adjusting for sociodemographic (age, sex, site, income, and education) and health factors (comorbidity, depressive symptoms, overweight/obesity, and knee pain). Our analyses included adults ages 49-84 years who participated in accelerometer monitoring at the Osteoarthritis Initiative 48-month visit (n = 1,142 with RKOA and n = 747 at risk of RKOA).
Two percent of African Americans and 13.0% of whites met the guidelines. For adults with and at risk of RKOA, significantly lower rates of guidelines attainment among African Americans compared to whites were partially attenuated by health factor differences, particularly overweight/obesity and knee pain (with RKOA: adjusted odds ratio [OR] 0.24, 95% confidence interval [95% CI] 0.08-0.72; at risk of RKOA: OR 0.28, 95% CI 0.07-1.05).
Despite known benefits from physical activity, attainment of the physical activity guidelines among persons with and at risk of RKOA was low. African Americans were 72-76% less likely than whites to meet the guidelines. Culturally relevant interventions and environmental strategies in the African American community targeting overweight/obesity and knee pain may reduce future racial/ethnic differences in physical activity and improve health outcomes.
本横断面研究调查了患有或有罹患放射学膝关节骨关节炎（RKOA）风险的人群中，在达到 2008 年美国卫生与公众服务部体力活动指南有氧活动部分（≥150 分钟/周，每次≥10 分钟，至少 150 分钟/周）方面的种族/民族差异。
我们使用多因素逻辑回归评估了非裔美国人和白人在达到指南标准方面的差异，调整了社会人口统计学因素（年龄、性别、部位、收入和教育）和健康因素（合并症、抑郁症状、超重/肥胖和膝关节疼痛）。我们的分析包括在骨关节炎倡议 48 个月访视时进行加速计监测的 49-84 岁成年人（有 RKOA 的 n=1142 例，有罹患 RKOA 风险的 n=747 例）。
2%的非裔美国人和 13.0%的白人达到了指南标准。对于患有和有罹患 RKOA 风险的成年人，与白人相比，非裔美国人达到指南标准的比例明显较低，这部分归因于健康因素的差异，尤其是超重/肥胖和膝关节疼痛（有 RKOA：调整后的比值比[OR]0.24，95%置信区间[95%CI]0.08-0.72；有罹患 RKOA 风险：OR 0.28，95%CI 0.07-1.05）。
尽管体力活动有已知的益处，但患有和有罹患 RKOA 风险的人群达到体力活动指南标准的比例较低。非裔美国人达到指南标准的可能性比白人低 72-76%。针对超重/肥胖和膝关节疼痛的、在非裔美国人社区中具有文化相关性的干预措施和环境策略可能会减少未来体力活动方面的种族/民族差异，并改善健康结果。
