Stanford Sleep Study Finds Huami Smartwatch Provides Clinical-Grade Accuracy
Stanford Sleep Study Finds Huami Smartwatch Provides Clinical-Grade Accuracy
Amazfit Arc Tracks and Detects Sleep Phases Better Than $1,000 Alternative
Amazfit Arc比1,000美元的替代產品更好地跟蹤和檢測睡眠階段
Huami, the second largest wearables company globally1, announced today the results of its wearable device sleep study with Stanford University Center for Sleep Sciences and Medicine, which conducts research and clinical and educational programs to improve patient care. According to the results of the study, Huami’s Amazfit Arc , a consumer wearable device, tracks sleep and wake periods with better accuracy than a commonly used clinical-grade actigraph, suggesting that Arc is a cost-effective research alternative for large-scale, clinical studies and trials.
全球第二大可穿戴設備公司華米今天宣佈了其與斯坦福大學睡眠科學和醫學中心合作的可穿戴設備睡眠研究結果，該中心開展研究、臨牀和教育項目，以改善患者護理。根據這項研究的結果，華米的Amazfit Arc是一款消費可穿戴設備，比常用的臨牀級活動記錄儀更準確地跟蹤睡眠和清醒時間，這表明Arc是大規模臨牀研究和試驗的一種性價比高的研究選擇。
Researchers studied minute-by-minute activity data collected from two different wearables -- Amazfit Arc and Actiwatch Spectrum by Philips -- which were worn by 31 participants over a 48-hour period. Twelve participants had no significant health issues or sleep disorders and the remaining 19 participants were patients from the Stanford University sleep clinic. Time-stamped data from each participant was recorded and compared. Researchers concluded that Arc and Actiwatch data were highly correlated, with the Arc yielding fundamentally similar sleep scoring metrics as to Actiwatch.
研究人員研究了從兩種不同的可穿戴設備--Amazfit Arc和飛利浦的Actiwatch Spectrum--收集的每分鐘活動數據，31名參與者在48小時內佩戴了這兩款可穿戴設備。12名參與者沒有明顯的健康問題或睡眠障礙，其餘19名參與者是斯坦福大學睡眠診所的患者。每個參與者的時間戳數據都被記錄下來並進行了比較。研究人員得出結論，Arc和Actiwatch的數據高度相關，Arc產生的睡眠評分指標與Actiwatch基本相似。
“Actigraphs are widely used portable wrist-worn devices that record the amount and timing of a person’s sleep and wake, but their clinical use is highly limited by their expense,” said Elaine Huo, Head of U.S. Marketing for Huami. “Until now, there was a lack of independent validation for cost-effective research alternatives. This study is the first of its kind to prove that a consumer wearable device can be used as an actigraph for sleep monitoring and that Amazfit Arc is able to produce data comparable to a research-grade actigraph.”
華米美國市場部主管Elaine Huo表示：“Actigraph是一種廣泛使用的便攜式手腕設備，可以記錄人的睡眠和醒來時間和時間，但它們的臨牀應用受到費用的高度限制。”“到目前為止，缺乏對具有成本效益的研究替代方案的獨立驗證。這項研究首次證明消費者可穿戴設備可以作為睡眠監測的活動記錄儀，Amazfit Arc能夠產生可與研究級活動記錄儀相媲美的數據。
Additional Study HighlightsThe auto- and low-scoring settings on the Actiwatch software (Actiware) were used to determine sleep and wake from the Actiwatch data and were used as the comparators.Receiver operating characteristic curves were used to optimize the relationship between the devices.Minute-by-minute Arc and Actiwatch data were highly correlated (r = 0.94, Spearman correlation) over the 48-h study period.Treating the Actiwatch auto scoring as the gold standard for determination of sleep and wake, Arc has an overall accuracy of 99.0% ± 0.17% (SEM), a sensitivity of 99.4% ± 0.19%, and a specificity of 84.5% ± 1.9% for the determination of sleep.As compared to the Actiwatch low scoring, Arc has an overall accuracy of 95.2% ± 0.36%, a sensitivity of 95.7% ± 0.47%, and a specificity of 91.7% ± 0.60% for the determination of sleep.
其他研究要點Actiwatch軟件(Actiware)上的自動評分和低評分設置用於從Actiwatch數據中確定睡眠和喚醒，並用作比較器。接收器操作特徵曲線用於優化設備之間的關係。在48小時的研究週期中，每分鐘Arc和Actiwatch數據高度相關(r=0.94，Spearman相關性)。將Actiwatch自動評分作為確定睡眠和喚醒的金標準，Arc的總體準確率為99.0與Actiwatch低分值相比，Arc對睡眠判定的總體準確率為95.2%±0.36%，靈敏度為95.7%±0.47%，特異度為91.7%±0.60%，與Actiwatch低評分值相比，ARC對睡眠判定的準確率為95.2%±0.36%，敏感度為95.7%±0.47%，特異度為91.7%±0.60%。
“We are pleased to provide researchers worldwide with an opportunity to advance the field of sleep study like never before and to offer consumers medical-grade data accuracy for less than $70 USD,” added Huo. “The promising results of the Stanford sleep study is another significant milestone for Huami and largely confirms what users and reviewers have been touting from the beginning -- that Amazfit offers the best low-key casual smartwatch around at a remarkable bargain, just like the Casio of the 21st century .”
“我們很高興能為世界各地的研究人員提供一個前所未有地推進睡眠研究領域的機會，並以不到70美元的價格為消費者提供醫療級的數據準確性，”霍建華補充道。“斯坦福睡眠研究的令人振奮的結果對華米來説是又一個重要的里程碑，這在很大程度上證實了用户和評論家從一開始就在吹捧的東西--Amazfit以驚人的價格提供了最好的低調休閒智能手錶，就像21世紀的卡西歐(Casio)一樣。”
