Regular physical activity (PA) is a valued part of cystic fibrosis (CF) care. Although the accelerometer, SenseWear Armband (SWA), accurately measures habitual PA in CF, it is mostly used for research purposes. For the first time, we analyzed different methods of measuring PA in daily life by the use of smartphones and other electronic devices such as smartwatch and Fitbit.
Twenty-four stable adults with CF (mean age 37.5 ± 11.5SD yrs.; FEV 58 ± 19% predicted, BMI 22.9 ± 3.2) were studied. Daily PA was monitored for seven consecutive days. All patients wore the accelerometer SWA and at the same time they monitored PA with the electronic device they used routinely. They were allocated into one of four arms according to their device: Smartwatch, Fitbit, Android smartphones and iOS smartphones. PA related measurements included: duration of PA, energy expenditure, number of steps.
There was a good agreement between SWA and Fitbit for number of steps (p = 0.605) and energy expenditure (p = 0.143). iOS smartphones were similar to SWA in monitoring the number of steps (p = 0.911). Significant differences were found between SWA and both Smartwatch and Android smartphones.
Fitbit and iOS smartphones seem to be a valuable approach to monitor daily PA. They provide a good performance to measure step number compared to SWA.
规律的体育活动（PA）是囊性纤维化（CF）护理的重要组成部分。尽管加速度计（SenseWear臂带，SWA）能准确测量CF患者的日常PA，但它主要用于研究目的。我们首次分析了使用智能手机以及智能手表和Fitbit等其他电子设备测量日常生活中PA的不同方法。
对24名病情稳定的成年CF患者（平均年龄37.5±11.5标准差岁；预测FEV为58±19%，BMI为22.9±3.2）进行研究。连续七天监测日常PA。所有患者均佩戴加速度计SWA，同时使用他们日常使用的电子设备监测PA。根据他们使用的设备将其分为四组之一：智能手表组、Fitbit组、安卓智能手机组和iOS智能手机组。与PA相关的测量指标包括：PA持续时间、能量消耗、步数。
SWA与Fitbit在步数（p = 0.605）和能量消耗（p = 0.143）方面具有良好的一致性。iOS智能手机在监测步数方面与SWA相似（p = 0.911）。SWA与智能手表和安卓智能手机之间均存在显著差异。
Fitbit和iOS智能手机似乎是监测日常PA的有效方法。与SWA相比，它们在测量步数方面表现良好。
