    The Global Burden of Animal Diseases (GBADs) programme follows a multistage process to produce disease burden estimates in livestock and farmed aquatic animal production systems. The GBADs programme has broad goals of inclusivity, transparency and rigour. Meeting those goals means providing users of all levels of technical expertise with a clear explanation of the programme\'s output. In this way, the meaning and limitations of those results are clearly communicated, minimising the risk of misinterpretation. The first published estimates of disease burden have been calculated at farm level using a new metric called the Animal Health Loss Envelope. This metric estimates the cost of lost productivity and expenditure on disease control for profit-maximising producers by comparing current system performance to a hypothetical ‘ideal health\'scenario. This ideal is a farm-specific concept and is critically different from an ideal health state when physiologically defined. The metric and its key concepts are described in this article.
    Le programme \" Impact mondial des maladies animales \" (GBADs) procède par analyses successives pour générer des estimations de l\'impact des maladies dans les systèmes de production d\'animaux terrestres et aquatiques. Le programme GBADs s\'est fixé des objectifs ambitieux d\'inclusivité, de transparence et de rigueur. Pour que ces objectifs soient tenus, tous les utilisateurs du programme, quel que soit leur niveau de compétences techniques, doivent y trouver une explication claire des résultats produits. La signification et les limites de ces résultats sont ainsi clairement exposées, ce qui minimise les risques d\'erreurs d\'interprétation. Les premières estimations publiées de l\'impact des maladies ont été calculées à l\'échelle des élevages, en faisant appel à un nouvel indicateur dénommé \" enveloppe des pertes sanitaires animales \". Cet indicateur estime le coût des pertes de productivité et les dépenses liées au contrôle des maladies chez des éleveurs cherchant une maximisation des profits, en comparant les performances du système actuel avec ceux d\'un scénario hypothétique de \" santé idéale \". Cet idéal est un concept forgé spécifiquement pour chaque exploitation et diffère donc radicalement de la situation sanitaire idéale définie par des critères physiologiques. L\'auteur décrit l\'indicateur et ses concepts essentiels.
    El programa sobre el Impacto Global de las Enfermedades Animales (GBADs) sigue un proceso de varias etapas para elaborar estimaciones del impacto de las enfermedades en los sistemas de producción ganadera y de animales acuáticos. El programa GBADs tiene como objetivos generales la inclusión, la transparencia y el rigor. Cumplir dichos objetivos implica proporcionar a los usuarios, independientemente de su nivel de conocimientos técnicos, una explicación clara de los resultados del programa. De esta manera, el significado y las limitaciones de dichos resultados se comunican con claridad, lo que minimiza el riesgo de interpretaciones erróneas. Las primeras estimaciones publicadas sobre el impacto de las enfermedades se han calculado a nivel de explotación utilizando una medida denominada \"cartera de pérdidas en sanidad animal\". Dicha medida calcula los costos de la pérdida de productividad y los gastos en control de enfermedades para los productores que buscan la maximización de los beneficios comparando el desempeño actual del sistema con un escenario hipotético de \"sanidad ideal\". Este ideal es un concepto específico de cada explotación y difiere mucho del estado de sanidad ideal en términos fisiológicos. En este artículo se describen tanto la medida como sus conceptos clave.

    背景:赌博及其对人类健康和福祉的有害影响是许多国家的重大公共卫生问题,电子赌博机(EGM)被认为是最有害的赌博形式之一。以前的研究已经建立了EGM可访问性之间的关联,支出,赌博的伤害,以及社区的社会经济地位(SES)。然而,对SES和EGM可访问性对个人玩家支出的直接影响的理解有限。先前对支出的估计通常依赖于自我报告的数据或场地一级的收入统计数据。本研究使用高空间分辨率的社会经济数据以及基于个人账户的位置和支出(销售点)数据(71,669名参与者,745EGM场馆),以探索EGM可及性与邻里SES之间的关联,并检查邻里居民的EGM支出是否与EGM可及性和邻里SES相关。
    方法:玩家帐户数据包括位于赫尔辛基地区的每个EGM场地的整个EGM赌博人群的家庭位置和支出信息,芬兰。使用有关社会经济变量的高分辨率(250×250m)网格级数据来获取参与者的当地社会经济条件。使用从玩家帐户数据得出的校准重力模型来估计每个网格单元的EGM可访问性。统计分析包括相关性分析,空间自相关分析,和回归模型。
    结果:首先,在当地SES较低的地区,EGM可及性水平明显较高。第二,回归分析显示,较高的EGM可及性和较低的本地SES与每个成年人每年较高的损失相关。这些结果,结合视觉和空间自相关分析,透露EGM赌博的可及性高度集中,特别是在社会经济较低的社区,EGM支出水平较高。
    结论:结果为未来关于赌博危害的空间研究奠定了基础,支出,可访问性,和SES利用关于球员和场馆之间互动的详细账户数据。结果强调了在调节EGM可达性时空间限制的重要性,特别是在人口脆弱的地区,作为公共卫生和危害预防的关键措施。结果还可以在地方一级采取有针对性的赌博伤害预防行动。
    BACKGROUND: Gambling and its harmful effects on human health and well-being represent a significant public health concern in many countries, with electronic gambling machines (EGMs) recognized as one of the most detrimental forms of gambling. Previous research has established an association between EGM accessibility, expenditure, gambling harm, and the socioeconomic status (SES) of neighborhoods. However, there is limited understanding of the direct impact of SES and EGM accessibility on individual player expenditures. Prior estimations of expenditure often rely on self-reported data or venue-level revenue statistics. This study uses high spatial resolution socioeconomic data together with individual-level account-based location and expenditure (point of sales) data (71,669 players, 745 EGM venues) to explore the association between EGM accessibility and neighborhood SES and to examine whether the EGM expenditure of neighborhood residents is associated with EGM accessibility and neighborhood SES.
    METHODS: Player account data include information on the home location and expenditure of the entire EGM gambling population across every EGM venue located in the Helsinki region, Finland. High-resolution (250 × 250 m) grid-level data on socioeconomic variables were used to obtain the local socioeconomic conditions of the players. EGM accessibility was estimated for every grid cell using a calibrated gravity model derived from the player account data. Statistical analyses included correlation analysis, spatial autocorrelation analysis, and regression models.
    RESULTS: First, significantly higher levels of EGM accessibility were found in areas with lower local SES. Second, regression analysis revealed that both higher EGM accessibility and lower local SES were associated with higher annual losses per adult. These results, in combination with visual and spatial autocorrelation analyses, revealed that accessibility to EGM gambling is highly concentrated, especially in lower socioeconomic neighborhoods with higher levels of EGM expenditure.
    CONCLUSIONS: The results lay the groundwork for future spatial research on gambling harm, expenditure, accessibility, and SES utilizing detailed account data on the interaction between players and venues. The results underscore the importance of spatial restrictions when regulating EGM accessibility, particularly in areas with vulnerable populations, as a crucial measure for public health and harm prevention. The results also enable targeted gambling harm prevention actions at the local level.

    目标:澳大利亚人在赌博上的人均花费比世界上任何其他国家都多。电子游戏机(EGM)支出占该支出的近90%。迄今为止,还没有一项研究对赌博支出与犯罪之间的关系进行了严格的纵向分析。这项研究旨在估计赌博支出与犯罪之间的短期和长期关系。
    方法:使用面板自回归分布滞后(ARDL)模型进行纵向分析。
    方法:记录在新南威尔士州(NSW)犯下的财产和暴力犯罪,澳大利亚,2015年12月28日至2020年1月5日。
    方法:每月EGM总支出利润,按地方政府区域(LGA)划分。每月记录的袭击率,闯入并窃取(住宅),闯入和偷窃(非住宅),闯入并窃取(总计),机动车盗窃,从机动车上偷东西,从零售店偷东西,从这个人那里偷东西,偷窃(总)和欺诈。
    结果:新南威尔士州赌博支出每增加10%,每年增加7.4%的攻击,违反和进入(居住)犯罪增加10.5%;违反和进入(非居住)犯罪增加10.3%;机动车盗窃犯罪增加11%;从机动车犯罪偷窃增加8.2%;欺诈犯罪增加7.4%。
    结论:在新南威尔士州,电子游戏支出似乎与财产和暴力犯罪呈正相关,澳大利亚。
    OBJECTIVE: Australians spend more per capita on gambling than any other country in the world. Electronic gaming machines (EGM) expenditure accounts for almost 90% of this expenditure. No study to date has conducted a rigorous longitudinal analysis of the relationship between gambling expenditure and crime. This study aimed to estimate the short- and long-run relationship between gambling expenditure and crime.
    METHODS: Longitudinal analysis using panel autoregressive distributed lag (ARDL) modelling.
    METHODS: Recorded property and violent crimes committed in New South Wales (NSW), Australia, between 28 December 2015 and 5 January 2020.
    METHODS: Monthly gross EGM expenditure profit, broken down by Local Government Area (LGA). Monthly recorded rates of assault, break enter and steal (dwelling), break enter and steal (non-dwelling), break enter and steal (total), motor vehicle theft, stealing from a motor vehicle, stealing from a retail store, stealing from the person, stealing (total) and fraud.
    RESULTS: Each 10% increase in gambling expenditure in NSW is associated with annual: 7.4% increase in assaults, 10.5% increase in break and enter (dwelling) offences; 10.3% increase in break and enter (non-dwelling) offences; 11% increase in motor vehicle theft offences; 8.2% increase in stealing from motor vehicle offences; and 7.4% increase in fraud offences.
    CONCLUSIONS: Electronic gaming expenditure appears to be positively associated with property and violent crime in New South Wales, Australia.

    背景:了解寻求医疗保健的行为并检查医疗支出可以帮助确定获得医疗保健的可能障碍,并指导更有效和更具包容性的医疗保健系统。这项研究旨在评估埃尔比勒人口样本中的医疗寻求行为和自付医疗支出,伊拉克。
    方法:我们在埃尔比勒进行了这项横断面研究,伊拉克库尔德斯坦地区,2023年10月至12月。414名成年人的便利样本完成了一项自我管理的在线调查。收集了以下数据:最近患病,社会人口统计学特征,接受的医疗保健类型,和医疗保健的成本。
    结果:报告的最常见的健康状况是传染病(16.3%),肌肉骨骼问题(13.1%),和非传染性疾病(12.7%)。大约85%的有健康状况需要护理的患者寻求医疗保健;大多数去过私人诊所(46.3%)和私人医院(18.6%)。以美元计的自付医疗总支出中位数为117.3(四分位距(IQR)=45.6-410.0)。首次访问私人医疗机构的参与者的总费用中位数(135.5美元,IQR=57.3-405.6)比首次访问公共设施的参与者(76.8美元,IQR=16.1-459.7)大得多。≥60年的参与者花费的时间明显多于<14年的参与者(332美元,95%CI=211-453,p<0.001)。已婚参与者的支出明显高于未婚参与者(97美元,95%CI=1至192,p=0.047)。非传染性疾病的卫生支出明显高于传染性疾病(232美元,95%CI=96-368,p=0.001)。在调整协变量后,年龄≥60岁与更高的支出独立相关(305美元,95%CI=153-457,p<0.001).
    结论:大多数参与者寻求正规医疗服务,更喜欢私营部门。从私人设施寻求护理的费用比从公共设施寻求护理的费用高得多,这表明获得医疗保健的潜在障碍,特别是负担能力。调查结果强调了评估现有医疗保健政策以提高有效性并确定需要改进的领域的重要性。这项研究可以帮助政策制定者和医疗保健提供者设计有效的干预措施,有效地分配资源,改善医疗保健服务。
    BACKGROUND: Understanding healthcare-seeking behavior and examining health expenditures can help determine possible barriers to accessing healthcare and direct more effective and inclusive healthcare systems. This study aimed to evaluate healthcare-seeking behavior and out-of-pocket healthcare expenditure in a sample of the population in Erbil, Iraq.
    METHODS: We conducted this cross-sectional study in Erbil, Kurdistan Region of Iraq, from October to December 2023. A convenience sample of 414 adults completed a self-administered online survey. The following data were collected: recent illness, sociodemographic characteristics, type of healthcare received, and cost of healthcare.
    RESULTS: The most common health conditions reported were communicable diseases (16.3%), musculoskeletal problems (13.1%), and noncommunicable diseases (12.7%). Approximately 85% of patients with health conditions requiring care sought healthcare; most visited private clinics (46.3%) and private hospitals (18.6%). The median total out-of-pocket healthcare expenditure in US dollars was 117.3 (interquartile range (IQR) = 45.6-410.0). The median total cost was much greater for participants who first visited a private health facility (USD 135.5, IQR = 57.3-405.6) than those who first visited a public facility (USD 76.8, IQR = 16.1-459.7). Participants ≥ 60 years spent significantly more than those < 14 years (USD 332, 95% CI = 211-453, p < 0.001). Evermarried participants spent significantly more than unmarried (USD 97, 95% CI = 1 to 192, p = 0.047). Health expenditures were significantly greater for noncommunicable diseases than infectious diseases (USD 232, 95% CI = 96-368, p = 0.001). After adjusting for covariates, age ≥ 60 years was independently associated with higher spending (USD 305, 95% CI = 153-457, p < 0.001).
    CONCLUSIONS: Most participants sought care from formal health services, preferring the private sector. Seeking care from private facilities incurred significantly higher costs than seeking care from public ones, which suggests potential barriers to accessing healthcare, particularly affordability. The findings underscore the importance of evaluating existing healthcare policies to enhance effectiveness and identify areas for improvement. This study can help policymakers and healthcare providers design effective interventions, allocate resources efficiently, and improve healthcare delivery.

    目的:来自印度的大部分费用数据仅限于纯粹从医疗机构招募的患者,没有探索决定因素。因此,德里评估了门诊糖尿病护理的自付费用.
    方法:DEDICOM-II调查使用了两阶段的概率-按大小成比例的(系统)集群设计。选择了30个集群,每个地区招募25至30名受试者。我们使用问卷来估计药物的直接自付支出(OOPE),调查,咨询和旅行,不包括住院,然后分析了其决定因素和对护理质量的影响。
    结果:我们招募了843名受试者,平均年龄为53.1岁。糖尿病门诊护理的年度直接OOPE为116.3美元(95%CI93.8-138.9)或8074.8卢比(95%CI6512.9-9636.7),相当于家庭年收入的3.6%(95%CI2.9-4.3)。那些访问低收入群体的私人提供者的费用负担不成比例地高(19.1%)。疾病持续时间和胰岛素治疗预测年度OOPE较高,而公共设施的护理费用较低。对于那些坚持推荐的护理过程的人来说,成本更高。机构护理的护理质量更好,替代医学或自我护理的质量更差。
    结论:该研究提供了对德里社会经济和护理提供者范围内糖尿病管理的高成本的代表性估计。贫困患者因糖尿病而承受很高的经济负担,强调加强糖尿病护理公平性的必要性。
    OBJECTIVE: Much of the cost data from India is restricted to patients recruited purely from healthcare institutions and do not explore determinants. Therefore, the out of pocket expenditure for ambulatory diabetes care was evaluated in Delhi.
    METHODS: The DEDICOM-II survey used a two-stage probability-proportionate-to-size(systematic) cluster design. Thirty clusters were chosen to recruit 25 to 30 subjects per area. We used questionnaires to estimate the direct out-of-pocket expenditure (OOPE) on drugs, investigations, consultation and travel, excluding hospitalization, and then analysed its determinants and impact on quality of care.
    RESULTS: We enrolled 843 subjects with a mean age of 53.1 years. The annual direct OOPE on ambulatory care of diabetes was US$ 116.3 (95 % CI 93.8-138.9) or INR 8074.8 (95 % CI 6512.9-9636.7), corresponding to 3.6 %(95 % CI 2.9-4.3) of the yearly family income. The burden of expenses was disproportionately higher for those visiting private providers from lower-income groups(19.1 %). Duration of disease and treatment with insulin predicted higher annual OOPE while care at public facilities was less expensive. Cost was higher for those adhering to the recommended processes of care. Quality of care was better for institutional care and worse for alternative medicine or self-care.
    CONCLUSIONS: The study provides representative estimates of the high cost of diabetes management in Delhi across the socio-economic and care provider spectra. Poorer patients suffer a high financial burden from diabetes, highlighting the need for enhancing equity in diabetes care.

    我们讨论了澳大利亚联邦预算拨款对2024-2025年精神医疗保健的影响。有资助针对轻度焦虑和抑郁的基于人口的精神卫生倡议,但没有直接资助针对最严重和致残形式的精神疾病的服务,除了联邦现有的州/地区为基于州的卫生服务支付的款项。人们非常担心,英联邦的资金可能被错误分配给无效的干预措施,这些干预措施不太可能降低澳大利亚轻度焦虑和抑郁的人口患病率。资金可能会得到更好的分配,为包括精神分裂症在内的最严重和致残疾病患者提供有效的护理,双相情感障碍和严重抑郁症。
    We discuss the ramifications of the Commonwealth of Australia Budget allocations for mental healthcare for 2024-2025. There is funding for population-based mental health initiatives for milder anxiety and depression but no direct funding of services for the most severe and disabling forms of mental illness, other than pre-existing state/territory disbursements from the Commonwealth for state-based health services. There are substantial concerns that the Commonwealth funding has potentially been misallocated to ineffective interventions that are unlikely to reduce the population prevalence of mild anxiety and depression in Australia. Funds may have been better allocated to provide effective care for those with the most severe and disabling illnesses including schizophrenia, bipolar disorder and severe depression.

    目的:乳腺癌是全球女性中最常见的癌症。死亡率与发病率比(MIR)是反映筛查干预措施和治疗结果的有效性和可用性的指标。MIR可用于影响公共卫生策略。具有不同经济状况的国家之间的乳腺癌MIR与卫生支出之间的关联很重要,但已经进行了调查。本研究旨在阐明不同国家之间乳腺癌MIR与人类发展和健康支出之间的关系。
    方法:癌症发病率和死亡率来自GLOBOCAN数据库。通过将粗死亡率除以发病率来计算MIR。通过线性回归估算了50个国家的MIR和人类发展指数(HDI)变体与当前卫生支出(CHE)之间的关联。
    结果:乳腺癌发病率较高,但死亡率较低,在发达国家(高人类发展指数,CHE人均,CHE/GDP),与发展中国家相比。有利的MIR与高人类发展指数和高卫生支出国家相关(由人均CHE高,和CHE/GDP)(均p<0.001)结论:乳腺癌的MIR与不同国家之间的发展和医疗保健差异呈负相关。这意味着为医疗保健系统分配更多资源用于乳腺癌筛查和治疗可以改善疾病预后。我们的报告可能有助于公共卫生政策的制定。
    OBJECTIVE: Breast cancer is the most frequently diagnosed cancer among women worldwide. Mortality-to-incidence ratio (MIR) is a marker that reflects the efficacy and availability of screening interventions and treatment outcomes. MIR can be used to influence public health strategy. The association between the MIRs for breast cancer among countries with different economic statuses and health expenditure is important yet has been investigated. This study was aimed to elucidate the association between the breast cancer MIRs and the human development and health expenditure among different countries.
    METHODS: Cancer incidence and mortality rates were obtained from the GLOBOCAN database. The MIRs were calculated by dividing the crude rate of mortality to the incidence. Associations among the MIR and variants of human development index (HDI) and current health expenditure (CHE) in 50 countries were estimated via linear regression.
    RESULTS: Breast cancer had a higher incidence rate, but lower mortality rate, in developed countries (high HDI, CHE per capita, CHE/GDP), as compared with developing countries. Favorable MIRs were associated with a high HDI and high health expenditure countries (presented by high CHE per capita, and CHE/GDP) (both p < 0.001) CONCLUSION: The MIR for breast cancer is reversely correlated with the development and healthcare disparities among different countries. This implies that allocating more resources to healthcare systems for breast cancer screening and treatment can improve disease outcomes. Our report may be helpful for public health policy making.

    科学,技术,创新在推动经济增长和社会发展中发挥着至关重要的作用。STI测量,包括研究与开发(R&D)投资的计量,对于为支持一个国家的科技创新的政策和决策提供证据至关重要。在南非,人类科学研究委员会科学中心,技术和创新指标(CeSTII)has,代表科学与创新部(DSI),在过去的二十年中,进行了年度全国研发调查。作为其中的一部分,CeSTII维护了一个广泛的历史单位级调查答复数据库。迄今为止,该中心拥有丰富的精选研发调查数据系列。这些数据集是增强国家创新系统(NSI)内基于证据的决策的科技创新指标体系的关键工具。在这次调查中,CeSTII每年收集和报告该国的研发支出和人员数据,涉及五个部门:业务,非营利组织,政府,科学委员会,和高等教育机构。最近,这些单独的数据集已经被合并,以建立一个连贯的时间序列数据集,以减轻重复寻找历史数据的挑战,这可能是繁琐和耗时的过程。政府使用研发指标统计数据来为国家优先事项和所需研发资金水平以及监测和基准制定的科技创新政策提供信息。
    Science, technology, and innovation (STI) play a vital role in driving economic growth and social development. STI measurement, including the measurement of Research and Development (R&D) investment, is crucial in providing evidence for policy and decision-making to support STI in a country. In South Africa, the Human Sciences Research Council\'s Centre for Science, Technology and Innovation Indicators (CeSTII), has, on behalf of the Department of Science and Innovation (DSI), conducted the annual national R&D Survey over the past two decades. As part of this, CeSTII has maintained an extensive database of historic unit-level survey responses. To date, the centre has a rich repository of curated R&D survey data series. These datasets are key tools for enhancing the system of STI indicators for evidence-based policy-making within the National System of Innovation (NSI). In this survey, CeSTII annually collects and reports on the country\'s R&D expenditure and personnel data across five sectors: business, not-for-profit organisations, government, science councils, and higher education institutions. Recently, these individual datasets have been merged to establish a coherent time series dataset to mitigate the challenge of repeatedly seeking historical data, which may be cumbersome and time-intensive process. The R&D indicators statistics are used by the government to inform STI policy on R&D for national priorities and required R&D funding levels and for monitoring and benchmarking purposes.

    UNASSIGNED: By using the exponential smoothing and ARIMA models to forecast the income and expenditure of the old-age care insurance fund in 2022, the problems existing in the operation of the long-term care insurance fund are discussed.
    UNASSIGNED: In 2022, the income of the old-age insurance fund was 28.8934 million yuan, and the fund compensation expenditure was 28.4070 million yuan, with a slight balance of the fund. The highest relative errors of income and expenditure forecast models are -2.03% and - 2.76%, respectively. According to the results of fund expenditure, the annual financing standard should be 132.93 yuan/person, and the individual financing standard should be 66.47 yuan/person.
    UNASSIGNED: Through the integration of personal payment, welfare, sports lottery public welfare income, social donations, and other ways, we can gradually establish a multi-channel risk-sharing financing. We will appropriately raise the standard for individual financing and the annual contribution standard for individuals from 50 yuan to 66.47 yuan. This will promote sustainable development of long-term insurance system.

    背景:AppleWatch(AW)系列1为轮椅使用者提供了能量消耗(EE),但被发现不准确,误差约为30%,FitbitCharge2提供的心率(HR)的相应误差约为10%至20%。使用这些智能手表(SWs)的较新版本,预计会提高估计的EE和HR的准确性。
    目的:本研究旨在评估AW系列4(轮椅专用设置)和FitbitVersa(跑步机运行模式)在不同强度轮椅推进过程中估算EE和HR的准确性。
    方法:数据来自20名手动轮椅使用者(男性:n=11,女性:n=9;体重:平均75,SD19kg)和20名非残疾人士(男性:n=11,女性:n=9;体重:平均75,SD11kg)。在3个单独的测试日(0.5%,2.5%,或5%倾斜),而EE和HR是通过标准设备和AW或Fitbit收集的。平均绝对百分比误差(MAPE)用于指示EE和HR的标准设备与SWs之间的绝对一致性。此外,线性混合模型分析评估了运动强度的影响,性别,和组的SW错误。类别间相关系数用于评估标准设备和SWs之间的相对一致性。
    结果:AW低估了EE,轮椅使用者的MAPE为29.2%(SD22%),无残疾人士的MAPE为30%(SD12%)。Fitbit高估了EE,轮椅使用者的MAPE为73.9%(SD7%),无残疾人士的MAPE为44.7%(SD38%)。两个SWs都低估了HR。EE和HR的设备误差随两种SWs的强度而增加(所有比较:P<.001),两组之间唯一的显着差异是AW中的HR(轮椅使用者-5.27次/分钟;P=.02)。性别对EE的估计误差有显著影响,女性参与者的AW精度较差(-0.69kcal/min;P<.001),Fitbit精度较好(-2.08kcal/min;P<.001)。对于HR,仅在AW人群中发现性别差异,女性参与者的误差较小(5.23次/分钟;P=.02)。除2个阶段倾斜组合外,两个SWs的类别间相关系数均显示较差至中等的相对一致性(EE的AW:0.12-0.57,HR的AW:0.11-0.86;Fitbit:EE的0.06-0.85,HR的0.03-0.29)。
    结论:AW和Fitbit均不足以估计轮椅推进期间的EE或HR。AW低估了EE,Fitbit高估了EE,两个SWs都低估了HR。因此,当使用SWs作为训练轮椅使用者的强度调节和能量平衡或不平衡的工具时,需要谨慎。
    BACKGROUND: The Apple Watch (AW) Series 1 provides energy expenditure (EE) for wheelchair users but was found to be inaccurate with an error of approximately 30%, and the corresponding error for heart rate (HR) provided by the Fitbit Charge 2 was approximately 10% to 20%. Improved accuracy of estimated EE and HR is expected with newer editions of these smart watches (SWs).
    OBJECTIVE: This study aims to assess the accuracy of the AW Series 4 (wheelchair-specific setting) and the Fitbit Versa (treadmill running mode) for estimating EE and HR during wheelchair propulsion at different intensities.
    METHODS: Data from 20 manual wheelchair users (male: n=11, female: n=9; body mass: mean 75, SD 19 kg) and 20 people without a disability (male: n=11, female: n=9; body mass: mean 75, SD 11 kg) were included. Three 4-minute wheelchair propulsion stages at increasing speed were performed on 3 separate test days (0.5%, 2.5%, or 5% incline), while EE and HR were collected by criterion devices and the AW or Fitbit. The mean absolute percentage error (MAPE) was used to indicate the absolute agreement between the criterion device and SWs for EE and HR. Additionally, linear mixed model analyses assessed the effect of exercise intensity, sex, and group on the SW error. Interclass correlation coefficients were used to assess relative agreement between criterion devices and SWs.
    RESULTS: The AW underestimated EE with MAPEs of 29.2% (SD 22%) in wheelchair users and 30% (SD 12%) in people without a disability. The Fitbit overestimated EE with MAPEs of 73.9% (SD 7%) in wheelchair users and 44.7% (SD 38%) in people without a disability. Both SWs underestimated HR. The device error for EE and HR increased with intensity for both SWs (all comparisons: P<.001), and the only significant difference between groups was found for HR in the AW (-5.27 beats/min for wheelchair users; P=.02). There was a significant effect of sex on the estimation error in EE, with worse accuracy for the AW (-0.69 kcal/min; P<.001) and better accuracy for the Fitbit (-2.08 kcal/min; P<.001) in female participants. For HR, sex differences were found only for the AW, with a smaller error in female participants (5.23 beats/min; P=.02). Interclass correlation coefficients showed poor to moderate relative agreement for both SWs apart from 2 stage-incline combinations (AW: 0.12-0.57 for EE and 0.11-0.86 for HR; Fitbit: 0.06-0.85 for EE and 0.03-0.29 for HR).
    CONCLUSIONS: Neither the AW nor Fitbit were sufficiently accurate for estimating EE or HR during wheelchair propulsion. The AW underestimated EE and the Fitbit overestimated EE, and both SWs underestimated HR. Caution is hence required when using SWs as a tool for training intensity regulation and energy balance or imbalance in wheelchair users.
