There are many benefits associated with engaging in strength physical activity. Many studies did not examine the engagement of strength activity among wearable device users. This study aimed to examine the association between wearable device usage and engagement of strength activity in free-living settings using nationally representative data.
A total of 8250 adult wearable device users and nonusers from 8 states of the 2017 Behavioral Risk Factors Surveillance System were included in analysis. Multiple regression models were performed to determine the association between the dependent variables of strength activities and the independent variable of wearable devices.
Wearable device users were 1.26 (95% confidence interval, 1.01-1.81) times the odds of nonusers in engaging in strength activity. Users also had higher odds of meeting both the strength and aerobic physical activity guidelines than nonusers (odds ratio = 1.49; 95% confidence interval, 1.07-2.06; adjusted odds ratio = 1.43; 95% confidence interval, 1.02-2.00). No associations were found between wearable device utilization and frequency of strength activity per week.
Wearable device users were more likely to engage in strength activity than nonusers. However, additional studies are needed to determine the effectiveness of wearable devices in promoting strength activity.
进行力量型身体活动有很多好处。许多研究并未检查可穿戴设备使用者的力量活动参与情况。本研究旨在使用全国代表性数据，检验可穿戴设备使用与自由活动环境中力量活动参与之间的关联。
共纳入来自 2017 年行为风险因素监测系统 8 个州的 8250 名成年可穿戴设备使用者和非使用者。采用多元回归模型来确定依赖变量（力量活动）与独立变量（可穿戴设备）之间的关联。
与非使用者相比，可穿戴设备使用者参与力量活动的几率高 1.26 倍（95%置信区间，1.01-1.81）。与非使用者相比，使用者达到力量活动和有氧运动活动指南的几率也更高（比值比=1.49；95%置信区间，1.07-2.06；调整比值比=1.43；95%置信区间，1.02-2.00）。但未发现可穿戴设备利用率与每周力量活动频率之间存在关联。
与非使用者相比，可穿戴设备使用者更有可能参与力量活动。然而，需要进一步的研究来确定可穿戴设备在促进力量活动方面的效果。
