African American women (AAW) are in a unique position to be recruited into mobile (mHealth) weight management research and programs due to their high rates of obesity and their high ownership of smartphones.
This study examined smartphone usage, social media engagement, and willingness to participate in mHealth weight management among AAW in north-central Florida, United States.
A self-administered survey was completed by a convenience sample of 425 smartphone owners in north-central Florida.
Mean age was 34.84 ± 13.74, with age distribution of 18 to 29 (45%), 30 to 50 (39%), and 51+ years (17%). Mean body mass index was 29.52 ± 8.18. Most used smartphones to access the Internet daily and were engaged with eight social media sites, such as Facebook (85%), YouTube (75%), and Google+ (57%). Compared to those 51+, those 18 to 29 were more likely to use YouTube (odds ratio [OR] = 2.52, p = .017) and Instagram (OR = 10.90, p < .0001), but they were less likely to use Google+ (OR = 0.40, p = .009). Compared to those 51+, those 30 to 50 were more likely to use Instagram (β = 1.28, OR = 3.61, p = .014) and Facebook (β = 1.04, OR = 2.84, p < .006). Most were willing to participate in research that used text messages (73%), smartwatches/fitness trackers (69%), and smartphone apps (68%). Compared to those 51+, women 18 to 29 were more likely to report willingness to use a smartphone app (OR = 5.45, p < .0001) as were those 30 to 50 (OR = 3.14, p < .0001).
AAW's high ownership of smartphones, use of mHealth apps and tools, and willingness to participate in mHealth research has the potential to curb the obesity epidemic by participating in mHealth weight management programs and research.
由于非裔美国女性（AAW）肥胖率高，智能手机拥有率高，因此她们处于招募到移动（移动医疗）体重管理研究和项目中的独特地位。
本研究检查了美国中北部佛罗里达州 AAW 的智能手机使用情况、社交媒体参与度以及参与移动医疗体重管理的意愿。
对中北部佛罗里达州的 425 名智能手机拥有者进行了一项便利样本的自我管理调查。
平均年龄为 34.84 ± 13.74 岁，年龄分布为 18 至 29 岁（45%）、30 至 50 岁（39%）和 51 岁以上（17%）。平均体重指数为 29.52 ± 8.18。大多数人每天使用智能手机上网，并使用了八个社交媒体网站，如 Facebook（85%）、YouTube（75%）和 Google+（57%）。与 51 岁以上的人相比，18 至 29 岁的人更有可能使用 YouTube（优势比[OR] = 2.52，p =.017）和 Instagram（OR = 10.90，p <.0001），但不太可能使用 Google+（OR = 0.40，p =.009）。与 51 岁以上的人相比，30 至 50 岁的人更有可能使用 Instagram（β = 1.28，OR = 3.61，p =.014）和 Facebook（β = 1.04，OR = 2.84，p <.006）。大多数人愿意参与使用短信（73%）、智能手表/健身追踪器（69%）和智能手机应用程序（68%）的研究。与 51 岁以上的人相比，18 至 29 岁的女性更有可能报告愿意使用智能手机应用程序（OR = 5.45，p <.0001），而 30 至 50 岁的女性（OR = 3.14，p <.0001）也是如此。
AAW 拥有大量智能手机，使用移动医疗应用程序和工具，并且愿意参与移动医疗研究，这有可能通过参与移动医疗体重管理计划和研究来遏制肥胖症的流行。
