Latina women are less likely to report engaging in leisure-time physical activity (PA) than non-Latina white women. This study evaluated the 24-month impact of a faith-based PA intervention targeting Latinas.
The study is a cluster randomized controlled trial of a PA intervention or cancer screening comparison condition, with churches as the randomization unit. A total of 436 Latinas (aged 18-65 years) from 16 churches who engaged in low levels of self-report and accelerometer-based PA were enrolled. The experimental condition was a 24-month PA intervention, with in-person classes, social support, and environmental changes, led by community health workers (i.e., promotoras). At baseline, 12-, and 24 months, we assessed changes in accelerometer-based and self-reported moderate to vigorous physical activity (MVPA; primary outcomes). Secondary outcomes were light intensity activity, sedentary time, body mass index (BMI), and waist circumference.
After adjusting for sociodemographic factors, a mixed effects analysis found significant increases in self-reported leisure time MVPA (p < 0.005) and marginal increases in accelerometer-assessed MVPA (p < 0.08) 24 months post-baseline in the intervention compared to the attention-control condition. Data showed significant associations between PA class attendance and engaging in MVPA as assessed by self-report and accelerometry. No significant changes were found for light activity, sedentary time, BMI, or waist circumference.
Participants who attended the PA classes at least once a month engaged in significantly higher MVPA compared to those who did not. Maximizing engagement and maintenance strategies to enhance PA maintenance could contribute to important long-term health benefits.

拉丁裔女性参与休闲时间体育活动（PA）的比例低于非拉丁裔白人女性。本研究评估了一项针对拉丁裔女性的基于信仰的 PA 干预措施在 24 个月的影响。
该研究是一项针对 PA 干预或癌症筛查比较条件的聚类随机对照试验，以教堂为随机分组单位。共招募了来自 16 个教堂的 436 名（年龄 18-65 岁）低自我报告和基于加速度计的 PA 的拉丁裔女性。实验组是一个为期 24 个月的 PA 干预措施，由社区卫生工作者（即 promotoras）提供面对面课程、社会支持和环境变化。在基线、12 个月和 24 个月时，我们评估了基于加速度计和自我报告的中度至剧烈体力活动（MVPA；主要结果）的变化。次要结果是轻强度活动、久坐时间、体重指数（BMI）和腰围。
在调整了社会人口因素后，混合效应分析发现，与对照组相比，实验组在干预后 24 个月内自我报告的休闲时间 MVPA 显著增加（p<0.005），并且在加速度计评估的 MVPA 方面略有增加（p<0.08）。数据显示，PA 课程出勤率与自我报告和加速度计评估的 MVPA 之间存在显著关联。轻活动、久坐时间、BMI 或腰围没有明显变化。
每月至少参加一次 PA 课程的参与者与那些不参加的参与者相比，进行了明显更高水平的 MVPA。最大限度地提高参与度和维持策略，以增强 PA 的维持，可能有助于实现重要的长期健康益处。
