To examine the association between characteristics of social support for exercise and moderate-to-vigorous leisure-time physical activity (LTPA) among Latinas.
This cross-sectional study used baseline data from a cluster randomized controlled trial.
The study was conducted in 16 churches located in San Diego County.
Participants (N = 436) were Latinas between 18 and 65 years old who did not self-report >150 minutes or did not exceed 250 minutes of moderate-to-vigorous PA per week measured by accelerometer.
Latinas listed up to 6 individuals who had provided support for exercise within the past 6 months, including their gender, relationship with the respondent, types of support provided, and respondent's satisfaction with support. Self-reported LTPA was dichotomized (none vs any).
We generated dyads between Latinas who named ≥1 supporter (n = 323) and each supporter they named (n = 569 dyads). Logistic regression analyses were conducted using generalized estimating equations to adjust for multiple observations per participant.
Having an exercise partner (odds ratio [OR]: 2.16; 95% confidence interval [CI]: 1.01-4.62), help with household duties (OR: 2.70; 95% CI: 1.35-3.38), being "very much" satisfied with support (OR: 2.33; 95% CI: 1.26-4.30), and naming >2 supporters (OR: 2.57; 95% CI: 1.06-6.25) was positively associated with LTPA.
Findings suggest specific aspects of support for exercise that should be targeted in future interventions to promote LTPA.
研究拉丁裔女性中运动社会支持特征与中度至剧烈强度休闲时间身体活动（LTPA）之间的关联。
本横断面研究使用了一项整群随机对照试验的基线数据。
研究在圣地亚哥县的16所教堂进行。
参与者（N = 436）为18至65岁的拉丁裔女性，她们自我报告每周进行中度至剧烈强度身体活动的时间不超过150分钟或通过加速度计测量不超过250分钟。
拉丁裔女性列出在过去6个月内为其运动提供支持的多达6个人，包括他们的性别、与受访者的关系、提供的支持类型以及受访者对支持的满意度。自我报告的LTPA被分为两类（无运动支持与有运动支持）。
我们在至少提及1名支持者的拉丁裔女性（n = 323）与她们提及的每位支持者之间生成二元组（n = 569个二元组）。使用广义估计方程进行逻辑回归分析，以调整每位参与者的多次观察结果。
有运动伙伴（比值比[OR]：2.16；95%置信区间[CI]：1.01 - 4.62）、家务帮助（OR：2.70；95% CI：1.35 - 3.38）、对支持“非常”满意（OR：2.33；95% CI：1.26 - 4.30）以及提及超过2名支持者（OR：2.57；95% CI：1.06 - 6.25）与LTPA呈正相关。
研究结果表明，在未来促进LTPA的干预措施中，应针对运动支持的特定方面。
