背景:缺乏体力活动与亚裔美国人的不良健康结果有关,与其他种族和族裔群体相比,他们对体育活动指南的坚持程度最低。基于移动应用程序的干预措施是促进健康行为的一种有前途的方法。然而,在主要语言不是英语的亚裔美国人中,缺乏基于应用程序的干预措施来改善体育锻炼。
目的:这项试点研究旨在评估5周干预的可行性和可接受性,基于证据的手机应用程序与加速度计程序,为了促进中国人的体育锻炼,Tagalog-,或者说越南语的美国人.
方法:参与者是通过与社区组织合作招募的。该干预措施是根据一项为期12个月的体育锻炼随机对照试验进行的,该试验涉及针对英语成年人的应用程序和加速度计。社会人口统计学特征,生活方式因素,在基线访视时收集物理测量值.进行了7天的磨合期,以筛选可以佩戴FitbitOne(FitbitLLC)加速度计并完成应用程序的每日步骤日记的参与者。在为期4周的干预期间,参与者佩戴加速度计,并在app中报告他们每天的步数.参与者还收到每日信息,以加强面对面教育期间教授的关键内容,提醒他们输入步骤,并提供量身定制的反馈。可行性衡量指标是完成磨合期的合格参与者的百分比,以及在干预期内7天中至少5天使用应用程序日记的参与者的百分比。我们进行了研究后参与者访谈,以探讨整体干预的可接受性。
结果:在研究开始时,共有19名参与者入组,平均年龄为47岁(SD13.3;范围29-70岁),其中58%(n=11)是女性。在参与者中,26%(n=5)是中国人,32%(n=6)是越南人,42%(n=8)是菲律宾人。所有参与者都符合磨合标准,可以继续进行干预。对应用程序日记的依从性从第2周的74%(n=14)到第4周的95%(n=18)。加速度计每周的每日平均步数从磨合期的8451(SD3378)步数增加到第4周的10,930(SD4213)步。参与者报告了积极的经历,包括增加了行走的动力和能够监测他们的身体活动的乐趣。
结论:这是第一个针对多组分干预和循证手机应用程序的试点研究,旨在促进使用传统中文应用程序的亚裔美国人的体育锻炼,他加禄语,或者越南人,具有很高的可行性和可接受性。未来的工作重点是多语言移动应用程序,以解决亚裔美国人之间缺乏身体活动的差异。
BACKGROUND: Physical inactivity is associated with adverse health outcomes among Asian Americans, who exhibit the least adherence to physical activity guidelines compared with other racial and ethnic groups. Mobile app-based interventions are a promising approach to promote healthy behaviors. However, there is a lack of app-based interventions focused on improving physical activity among Asian Americans whose primary language is not English.
OBJECTIVE: This pilot study aimed to assess the feasibility and acceptability of a 5-week intervention using a culturally and linguistically adapted, evidence-based mobile phone app with an accelerometer program, to promote physical activity among Chinese-, Tagalog-, or Vietnamese-speaking Americans.
METHODS: Participants were recruited through collaborations with community-based organizations. The intervention was adapted from a 12-month physical activity randomized controlled trial involving the app and accelerometer for English-speaking adults. Sociodemographic characteristics, lifestyle factors, and physical measurements were collected at the baseline visit. A 7-day run-in period was conducted to screen for the participants who could wear a Fitbit One (Fitbit LLC) accelerometer and complete the app\'s daily step diary. During the 4-week intervention period, participants wore the accelerometer and reported their daily steps in the app. Participants also received daily messages to reinforce key contents taught during an in-person educational session, remind them to input steps, and provide tailored feedback. Feasibility measures were the percentage of eligible participants completing the run-in period and the percentage of participants who used the app diary for at least 5 out of 7 days during the intervention period. We conducted poststudy participant interviews to explore overall intervention acceptability.
RESULTS: A total of 19 participants were enrolled at the beginning of the study with a mean age of 47 (SD 13.3; range 29-70) years, and 58% (n=11) of them were female. Of the participants, 26% (n=5) were Chinese, 32% (n=6) were Vietnamese, and 42% (n=8) were Filipino. All participants met the run-in criteria to proceed with the intervention. Adherence to the app diary ranged from 74% (n=14) in week 2 to 95% (n=18) in week 4. The daily average steps per week from accelerometers increased each week from 8451 (SD 3378) steps during the run-in period to 10,930 (SD 4213) steps in week 4. Participants reported positive experiences including an increased motivation to walk and the enjoyment of being able to monitor their physical activity.
CONCLUSIONS: This is the first pilot study of a multicomponent intervention and evidence-based mobile phone app to promote physical activity among Asian Americans who use apps in traditional Chinese, Tagalog, or Vietnamese, which demonstrated high feasibility and acceptability. Future work focused on
multilingual mobile apps to address disparities in physical inactivity among Asian Americans should be considered.
