生活在美国的拉丁美洲成年人中，超过一半的人预计会在一生中患上2型糖尿病。尽管人们对使用智能手机减肥和预防糖尿病的兴趣越来越大，但相对较少的临床试验评估了拉丁美洲人群中基于移动的应用程序的干预措施的有效性。这项研究的目的是评估在拉丁美洲样本中，与商业上可用的Fitbit应用程序相结合的面对面减肥干预的潜在疗效，并探索与减肥相关的重要预测因素。在导入期之后，54名自我认定的身体质量指数（BMI）> 24.9 kg/m2的拉丁美洲人参加了一项为期8周的非对照试点研究，并接受了Fitbit Zip，其应用程序和两次根据糖尿病预防计划改编的面对面减肥课程。平均年龄为45.3（SD +/- 10.8）岁，61.1%出生于美国，平均BMI为31.4（SD +/- 4.1）kg/m2。参与者平均体重减轻了3.3（SD +/- 3.4）%（p < .0005）。我们还观察到腰围和臀围以及收缩压和舒张压在统计学上显著降低（p <0.001）。在控制人口统计学因素后，每周至少两次使用移动的应用程序体重日记（p = 0.01）和国际体力活动问卷评分的变化（p = 0.03）与体重百分比的变化相关。干预显示了这种干预的潜在疗效，应该在随机对照试验中进行正式评估。
More than half of Latino adults living in the USA are expected to develop type 2 diabetes in their lifetime. Despite the growing interest in smartphone use for weight loss and diabetes prevention, relatively few clinical trials have evaluated the efficacy of mobile app-based interventions in Latino populations. The aim of this study was to evaluate the potential efficacy of an in-person weight loss intervention in conjunction with a commercially available Fitbit app in a Latino sample at risk for type 2 diabetes and explore significant predictors associated with weight loss. After the run-in period, 54 self-identified Latinos with body mass index (BMI) > 24.9 kg/m(2) were enrolled in an 8-week uncontrolled pilot study, and received a Fitbit Zip, its app, and two in-person weight loss sessions adapted from the Diabetes Prevention Program. Mean age was 45.3 (SD +/- 10.8) years, 61.1% were born in the USA, and mean BMI was 31.4 (SD +/- 4.1) kg/m(2). Participants lost an average of 3.3 (SD +/- 3.4) % of their body weight (p < .0005). We also observed statistically significant reductions in hip and waist circumferences, and systolic and diastolic blood pressure (p < .001). After controlling for demographic factors, use of the mobile app weight diary at least twice a week (p = .01) and change in the International Physical Activity Questionnaire score (p = .03) were associated with change in percent body weight. The intervention showed the potential efficacy of this intervention, which should be formally evaluated in a randomized controlled trial.
