In the U.S., Latinos report particularly high levels of inactivity and related chronic illnesses and are in need of intervention. Thus, the purpose of the current study was to culturally and linguistically adapt an empirically supported, individually tailored physical activity print intervention for Latinos and then conduct an RCT of the modified program.
An RCT was conducted.
SETTING/PARTICIPANTS: The sample included 93 overweight/obese (80%) Latinas with low income and acculturation.
Data were collected in 2007-2008 and analyzed by intent-to-treat in 2009. Participants were randomly assigned to either (1) a culturally and linguistically adapted physical activity intervention (Seamos Activas) or (2) a wellness contact control condition.
Self-report physical activity, as measured pre- and post-intervention (6 months, 87% retention) by the 7-Day Physical Activity Recall.
Moderate-intensity (or greater) physical activity increased from an average of 16.56 minutes/week (SD=25.76) at baseline to 147.27 (SD=241.55) at 6 months in the intervention arm (n=45), and from 11.88 minutes/week (SD=21.99) to 96.79 (SD=118.49) in the wellness contact control arm (n=48). No between-group differences were seen in overall physical activity. Intervention participants reported significantly greater increases in cognitive (F[1, 91]=9.53, p=0.003) and behavioral processes of change (F[1, 91]=8.37, p=0.005) and available physical activity supplies and equipment at home (F[1, 91]=4.17, p=0.04) than control participants.
Results supported the hypothesized feasibility, acceptability, and preliminary efficacy of individually tailored physical activity print interventions among Latinas. Although more research is needed to corroborate these findings, such high-reach, low-cost approaches have great potential to positively affect public health.

在美国，拉丁裔报告的活动不足水平特别高，且与多种慢性疾病相关，因此他们非常需要干预。因此，本研究的目的是为拉丁裔人群对经过实证支持的、个体化的体力活动印刷干预措施进行文化和语言适应性调整，然后对修改后的方案进行 RCT。
进行了 RCT。
设置/参与者：该样本包括 93 名超重/肥胖（80%）、收入低且处于文化融合期的拉丁裔女性。
数据于 2007-2008 年收集，并于 2009 年按意向治疗进行分析。参与者被随机分配到以下两种情况之一：（1）文化和语言适应性体力活动干预（Seamos Activas）或（2）健康联系对照组。
通过 7 天体力活动回忆（在干预前和干预后 6 个月进行，87%的保留率）自我报告体力活动。
在干预组（n=45）中，中等强度（或更高强度）的体力活动从基线时的平均 16.56 分钟/周（SD=25.76）增加到 6 个月时的 147.27 分钟/周（SD=241.55），而在健康联系对照组（n=48）中，从 11.88 分钟/周（SD=21.99）增加到 96.79 分钟/周（SD=118.49）。总体体力活动方面未观察到组间差异。干预组参与者在认知（F[1,91]=9.53，p=0.003）和行为变化过程（F[1,91]=8.37，p=0.005）以及家中可用的体力活动用品和设备（F[1,91]=4.17，p=0.04）方面的报告显著增加。
结果支持个体化体力活动印刷干预措施在拉丁裔人群中具有假设的可行性、可接受性和初步疗效。尽管需要更多的研究来证实这些发现，但这种高覆盖率、低成本的方法具有极大的潜力来积极影响公共卫生。
