Latinas in the US report high levels of physical inactivity and are disproportionally burdened by related health conditions (eg, type 2 diabetes, obesity), highlighting the need for innovative strategies to reduce these disparities. A 1-month single-arm pretest-posttest design was utilized to assess the feasibility and acceptability of a culturally and linguistically adapted Internet-based physical activity intervention for Spanish-speaking Latinas. The intervention was based on the Social Cognitive Theory and the Transtheoretical Model. Changes in physical activity and related psychosocial variables were measured at baseline and the end of the 1-month intervention. The sample included 24 Latina adults (mean age, 35.17±11.22 years). Most (83.3%) were born outside the continental US. Intent-to-treat analyses showed a significant increase (P=.001) in self-reported moderate- to vigorous-intensity physical activity from a median of 12.5 min/wk at baseline to 67.5 min/wk at the 1-month assessment. Participants reported significant increases in self-efficacy as well as cognitive and behavioral processes of change. Nearly half of the participants (45.8%) reported advancing at least one stage of change during the course of the 1-month intervention. Findings support the feasibility and acceptability of using interactive Internet-based technology to promote physical activity among Latinas in Alabama.
美国的拉丁裔女性报告称身体活动水平较高，且因相关健康状况（如2型糖尿病、肥胖症）而承受着不成比例的负担，这凸显了采取创新策略来减少这些差异的必要性。采用为期1个月的单组前后测设计，以评估一种针对讲西班牙语的拉丁裔女性进行文化和语言调适的基于互联网的身体活动干预措施的可行性和可接受性。该干预措施基于社会认知理论和跨理论模型。在基线和1个月干预结束时测量身体活动及相关心理社会变量的变化。样本包括24名拉丁裔成年人（平均年龄35.17±11.22岁）。大多数人（83.3%）出生在美国本土以外。意向性分析显示，自我报告的中等至剧烈强度身体活动显著增加（P = 0.001），从基线时的中位数每周12.5分钟增加到1个月评估时的每周67.5分钟。参与者报告自我效能以及认知和行为改变过程有显著增加。近一半的参与者（45.8%）报告在1个月的干预过程中至少前进了一个改变阶段。研究结果支持使用交互式互联网技术促进阿拉巴马州拉丁裔女性身体活动的可行性和可接受性。
