Abstract：
OBJECTIVE: To (1) describe the socio-demographic and behavioural characteristics of older adults who use wearable devices for physical activity monitoring and (2) explore whether wearable device use increases the possibilities of meeting physical activity guideline recommendations among older adults and older adults with known cardiovascular disease or risk.
BACKGROUND: Finding ways to increase physical activity and reduce cardiovascular disease risk among older adults is a public health priority. Wearable technology has great potential for promoting physical activity among older adults.
METHODS: A secondary analysis of the national data.
METHODS: A nationally representative sample of older adults aged 65 years and older (mean age = 73.79 years, N = 1484) and a subsample of older adults with known cardiovascular disease or cardiovascular disease risk (mean = 74.32 years, N = 1098) was used in the analysis. All analyses were weighted to account for the complex survey design. This study was reported according to the STROBE checklist.
RESULTS: The overall prevalence of wearable device use among older adults and older adults with cardiovascular disease risk was 16% and 14%, respectively. Older adults with higher household incomes, better self-rated health, and greater exercise enjoyment were more likely to use wearable devices. Compared with non-users, older adult users were more likely to meet the recommended levels of moderate (55% vs. 31%) and strengthening activity guidelines (46% vs. 25%), but not of the sedentary behaviour guideline (69% vs. 62%). Similar findings were also seen in older adults with known cardiovascular disease or risk.
CONCLUSIONS: The uptake of wearable devices in older adults, particularly those with known cardiovascular disease or risk is still low. The use of wearable devices is an important facilitator of physical activity. It is critical to provide individualised support for their engagement.
CONCLUSIONS: Age-friendly design and individualised support are recommended to increase older adults\' adoption of wearable devices to improve their physical health.
UNASSIGNED: No patient or public contribution was involved in this study since we used publicly available data.

摘要：
目的：(1)描述使用可穿戴设备进行体力活动监测的老年人的社会人口统计学和行为特征，(2)探讨可穿戴设备的使用是否增加了老年人和已知心血管疾病或风险的老年人满足体力活动指南建议的可能性。
背景：寻找增加老年人体力活动和降低心血管疾病风险的方法是公共卫生的优先事项。可穿戴技术在促进老年人身体活动方面具有巨大潜力。
方法：对国家数据的二次分析。
方法：65岁及以上老年人的全国代表性样本（平均年龄=73.79岁，N=1484）和已知心血管疾病或心血管疾病风险的老年人的子样本（平均=74.32岁，在分析中使用N=1098)。所有分析都进行了加权，以考虑复杂的调查设计。这项研究是根据STROBE检查表报告的。
结果：老年人和有心血管疾病风险的老年人使用可穿戴设备的总体患病率为16％和14％，分别。家庭收入较高的老年人，更好的自我评价的健康，和更多的运动享受更有可能使用可穿戴设备。与非用户相比，年龄较大的成人用户更有可能达到建议的中等水平(55%与31%)和加强活动指南(46%与25%），但不是久坐行为指南(69%与62%）。在患有已知心血管疾病或风险的老年人中也看到了类似的发现。
结论：老年人使用可穿戴设备，特别是那些已知心血管疾病或风险仍然很低。可穿戴设备的使用是身体活动的重要促进者。为他们的参与提供个性化支持至关重要。
结论：建议采用年龄友好型设计和个性化支持，以增加老年人对可穿戴设备的采用，以改善他们的身体健康。
UASSIGNED：由于我们使用了公开的数据，本研究没有涉及患者或公众的贡献。
