在过去的十年里，拉丁美洲人的互联网接入显着增长。然而，尽管肥胖和糖尿病等生活方式相关疾病（尤其是拉丁裔女性）存在巨大差异，但目前还没有针对拉丁裔设计的基于互联网的身体活动干预措施。当前的研究测试了为期 6 个月的文化适应、个性化定制、基于西班牙语的互联网身体活动干预的效果。不活跃的拉丁裔 (N = 205) 被随机分配到定制体育活动互联网干预组或健康接触控制互联网组。两组参与者在 6 个月内都会收到按逐渐减少的时间表发送的电子邮件，提醒他们网站上的新内容。主要结果是 6 个月时每周进行的中度至剧烈体力活动分钟数 (MVPA)，通过 7 天体力活动回忆进行测量；活动也通过加速度计测量。加州大学圣地亚哥分校于 2011 年至 2014 年收集数据并于 2015 年进行分析。与对照组相比，干预组每周 MVPA 分钟数的增加显着更大（平均差 = 50.00，SE = 9.5，p < 0.01）。干预组中客观测量的 MVPA 的增加也显着更大（平均差异 = 31.0，SE = 10.7，p < .01）。干预组在 6 个月时也更有可能达到国家体育活动指南（OR = 3.12，95% CI 1.46–6.66，p < .05）。目前的研究结果表明，与健康接触控制互联网小组相比，这种通过互联网提供的个性化干预措施成功地提高了拉丁裔的 MVPA。 NCT01834287。
Internet access has grown markedly in Latinos during the past decade. However, there have been no Internet-based physical activity interventions designed for Latinos, despite large disparities in lifestyle-related conditions, such as obesity and diabetes, particularly in Latina women. The current study tested the efficacy of a 6-month culturally adapted, individually tailored, Spanish-language Internet-based physical activity intervention. Inactive Latinas (N = 205) were randomly assigned to the Tailored Physical Activity Internet Intervention or the Wellness Contact Control Internet Group. Participants in both groups received emails on a tapered schedule over 6 months to alert them to new content on the website. The primary outcome was minutes/week of moderate to vigorous physical activity (MVPA) at 6 months as measured by the 7-Day Physical Activity Recall; activity was also measured by accelerometers. Data were collected between 2011 and 2014 and analyzed in 2015 at the University of California, San Diego. Increases in minutes/week of MVPA were significantly greater in the Intervention Group compared to the Control Group (mean difference = 50.00, SE = 9.5, p < 0.01). Increases in objectively measured MVPA were also significantly larger in the Intervention Group (mean differences = 31.0, SE = 10.7, p < .01). The Intervention Group was also significantly more likely to meet national physical activity guidelines at 6 months (OR = 3.12, 95 % CI 1.46–6.66, p < .05). Findings from the current study suggest that this Internet-delivered individually tailored intervention successfully increased MVPA in Latinas compared to a Wellness Contact Control Internet Group.
