Physical activity (PA) levels vary across specific population groups, contributing to health inequalities. Little is known about how local authority leisure centers contribute to population PA and whether this differs by age, sex, or socioeconomic group.
The authors calculated weekly leisure center-based moderate/vigorous PA for 20,904 registered adult users of local authority leisure facilities in Northumberland, United Kingdom, between July 2018 and June 2019, using administrative data. The authors categorized activity levels (<30, 30-149, and ≥150 min/wk) and used ordinal regression to examine predictors for activity category achieved.
Registered users were mainly female (58.7%), younger (23.9% of users aged 18-29 y vs 10.1% of those aged 70+ y), and from the 2 most affluent socioeconomic quintiles (53.7%). Median weekly moderate/vigorous leisure center-based activity was 55 minutes per week (interquartile range: 30-99). Being female (odds ratio: 2.09; 95% confidence interval, 1.95-2.35), older (odds ratio: 1.14; 95% confidence interval, 1.11-1.16), and using a large facility (odds ratio: 1.21; 95% confidence interval, 1.03-1.42) were positive predictors of leisure center-based PA.
Older adults and females were more likely to be active and achieve the recommended PA levels through usage of the centers. Widespread use of this novel measure of leisure center-based activity would improve the understanding of how local authority leisure centers can address physical inactivity and its associated inequalities.
体育活动（PA）水平因特定人群群体而异，导致健康不平等。人们对地方当局休闲中心如何促进人群 PA 知之甚少，也不知道这种情况是否因年龄、性别或社会经济群体而异。
作者使用行政数据计算了 2018 年 7 月至 2019 年 6 月期间，英国诺森伯兰郡地方当局休闲设施 20904 名注册成年用户每周在当地休闲中心进行的中度/剧烈 PA，并将活动水平（<30、30-149 和≥150 min/wk）进行分类，并使用有序回归来检查达到活动类别的预测因素。
注册用户主要为女性（58.7%），年龄较小（23.9%的用户年龄在 18-29 岁，而 10.1%的用户年龄在 70 岁以上），且来自前两个最富裕的社会经济五分位数（53.7%）。每周中等/剧烈休闲中心活动的中位数为 55 分钟/周（四分位距：30-99）。女性（优势比：2.09；95%置信区间，1.95-2.35）、年龄较大（优势比：1.14；95%置信区间，1.11-1.16）和使用大型设施（优势比：1.21；95%置信区间，1.03-1.42）是休闲中心 PA 的积极预测因素。
老年人和女性更有可能通过使用这些中心积极活动并达到推荐的 PA 水平。广泛使用这种衡量休闲中心活动的新方法可以更好地了解地方当局休闲中心如何解决身体活动不足及其相关的不平等问题。
