目的：评估符合更新的2018年美国人身体活动指南的流行率（150分钟中等强度至剧烈强度的体力活动[MVPA]），并确定与指南实现相关的横截面因素，在一个以社区为基础的队列中，患有膝关节骨关节炎（OA）或膝关节骨关节炎风险升高的成年人。在骨关节炎倡议（OAI）参与者的一个子集中，对膝关节OA或膝关节OA风险增加的参与者进行1周的体力活动监测。计算加速度计测量的每周MVPA分钟数;评估社会人口统计学（年龄、性别、种族、教育和工作状态）和健康相关（体重指数[BMI]、合并症、抑郁症状、影像学膝关节OA和频繁的膝关节症状）因素。我们评估了符合2018年指南的患病率，并使用多变量部分比例优势模型来确定与指南达成相关的因素，控制模型中的其他因素。在1922名参与者中（年龄65.1 [标准差9.1]岁，BMI 28.4 [4.8] kg/m（2），55.2%女性），44.1%男性和22.2%女性符合2018年PA指南。与不符合2018年指南相关的调整后的横截面因素包括：女性、年龄较大、BMI较高、非白人、抑郁症状、不工作和频繁的膝关节症状。在社区招募的患有膝关节OA或膝关节OA高风险的成人中，超过50%的男性和近80%的女性未能达到2018年建议的每周至少150分钟的MVPA。研究结果支持在达到指南方面的性别和种族差异，并建议解决潜在的可改变因素（例如，BMI、抑郁症状和频繁的膝关节症状），以优化PA促进干预的获益。(C)2020年国际骨关节炎研究学会。由爱思唯尔有限公司出版。保留所有权利。
Objectives: Evaluate the prevalence of meeting the updated 2018 Physical Activity Guidelines for Americans (150 unbouted minutes in moderate-to-vigorous intensity physical activity [MVPA]) and determine cross-sectional factors associated with Guideline attainment in a community-based cohort of adults with or at elevated risk for knee osteoarthritis (OA).Methods: Physical activity was monitored for 1 week in a subset of Osteoarthritis Initiative (OAI) participants with or at increased risk for knee OA. Accelerometer-measured weekly MVPA minutes were calculated; sociodemographic (age, sex, race, education, and working status) and health-related (body mass index [BMI], comorbidity, depressive symptoms, radiographic knee OA, and frequent knee symptoms) factors were assessed. We evaluated the prevalence of meeting 2018 Guidelines and used multivariate partial proportional odds model to identify factors associated with Guideline attainment, controlling for other factors in the model.Results: Among 1922 participants (age 65.1 [standard deviation 9.1] years, BMI 28.4 [4.8] kg/m(2), 55.2% women), 44.1% men and 22.2% women met the 2018 PA Guidelines. Adjusted cross-sectional factors associated with not-meeting 2018 Guidelines were: women, older age, higher BMI, non-Whites, depressive symptoms, not working, and frequent knee symptoms.Conclusion: In community-recruited adults with or at high risk for knee OA, more than 50% of men and nearly 80% of women failed to achieve the 2018 recommended level of at least 150 weekly unbouted minutes of MVPA. Study findings support gender and racial disparity in Guideline attainment and suggest addressing potentially modifiable factors (e.g., BMI, depressive symptoms, and frequent knee symptoms) to optimize benefits in PA-promoting interventions.
