A personalized mobile health intervention (iSTEP) aims to promote a Mediterranean diet and increase physical activity, thereby improving neurocognitive functioning among persons living with HIV (PLWH). This article describes a qualitative study conducted to develop iSTEP for PLWH, including assessment of diet habits and preferences for tracking physical activity.
Two focus groups, with seven and 13 PLWH respectively, discussed barriers and facilitators of a healthy diet and provided feedback to refine iSTEP components, including the feasibility of using a Fitbit and the content of text messages designed to encourage improved diet and physical activity.
Focus group discussions revealed several healthy diet barriers, including housing instability, time required for food preparation, cost of healthy food, depression, gastrointestinal issues, physical disability, and changes in appetite since HIV diagnosis. Participant-identified healthy diet facilitators included affordable price options for healthy food, a structured food plan, desire to modify appearance or weight, access to medical professionals, motivation for disease prevention, and social support. Participants endorsed wearing a Fitbit on the wrist and receiving text messages as useful methods to monitor and encourage a better diet and greater physical activity.
These findings assisted the expansion of a mobile health intervention that promotes health behaviors in order to improve neurocognitive outcomes among PLWH.

个性化移动健康干预(iSTEP)旨在促进地中海饮食和增加身体活动,从而改善 HIV 感染者(PLWH)的神经认知功能。本文描述了一项定性研究,该研究旨在为 PLWH 开发 iSTEP,包括评估饮食习惯和跟踪身体活动的偏好。
两个焦点小组,分别有 7 名和 13 名 PLWH 参加,讨论了健康饮食的障碍和促进因素,并提供了反馈意见,以完善 iSTEP 组件,包括使用 Fitbit 的可行性以及旨在鼓励改善饮食和身体活动的短信内容。
焦点小组讨论揭示了一些健康饮食的障碍,包括住房不稳定、准备食物所需的时间、健康食品的成本、抑郁、胃肠道问题、身体残疾以及 HIV 诊断后食欲的变化。参与者确定的健康饮食促进因素包括健康食品的负担得起的价格选择、结构化的饮食计划、改变外貌或体重的愿望、获得医疗专业人员的机会、预防疾病的动机和社会支持。参与者赞成在手腕上佩戴 Fitbit 并接收短信,认为这是监测和鼓励更好的饮食和更多身体活动的有用方法。
这些发现有助于扩大移动健康干预措施,促进健康行为,以改善 PLWH 的神经认知结果。
