A PILOT TEST OF ELOG: REAL-TIME MOBILE ENERGY BALANCE RESEARCH SYSTEM

该子项目是利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得主要资金， 因此可以在其他CRISP条目中表示。列出的机构是 中心，不一定是研究者的机构。 医疗保健专业人员面临的一个重大挑战是长期维持客户的健康体重。成功保持健康体重的人更有可能承担自我调节能量平衡的责任。 能量平衡是饮食、体力活动和遗传对个体一生中生长和体重的综合影响。 没有研究工具可以以综合和可验证的方式捕获实时能量平衡，并且对研究参与者或体重管理客户端来说是用户友好的。 这是一项试点研究，旨在评估研究参与者使用电子能量平衡日志或eLog原型版本的易用性。 eLog是一种计算机辅助系统，用于主观（电子记录的食物和活动日志）和客观（消耗的食物/饮料重量和运动测量）实时测量和收集受试者的能量平衡。该工具不是一种辅助诊断和/或治疗的工具，而是评估能量摄入和消耗的工具。 这个原型是一个手持个人计算机（手持PC），它是由普林斯顿多媒体技术核心（PMT）根据NCI SBIR第一阶段合同HHSN 261200544010 C开发的。 该软件公司专门为GCRC生物营养素核心开发了其他生物营养素相关软件。该原型的测试将由俄亥俄州州立大学和爱荷华州大学的GCRC生物核芯进行。 本初步研究涉及20例（每个研究中心10例）年龄在18-65岁之间的男性和/或女性受试者，他们将接受使用eLog收集实时食物摄入和体力活动数据的培训。评价将评估以下各项的可用性： 1）连接到手持PC的秤，通过称量食物来捕获精确的食物摄入记录; 2)在手持PC上输入估计的食物摄入量记录，以及 3)通过数字活动记录器监测身体活动 4）（未来的测试将包括使用加速计来评估运动的客观测量）。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. A significant challenge for healthcare professionals is the long-term maintenance of a clients healthy body weight. Individuals who succeed in maintaining a healthy body weight are more likely to assume responsibility for self-regulation of their energy balance. Energy balance is the integrated effect of diet, physical activity, and genetics on the growth and body weight of the individual over his/her lifetime. There are no research tools that capture real-time energy balance in an integrated and verifiable manner and which are user-friendly for research participants or weight management clients. This is a pilot study to evaluate the ease of use, by study participants, of a prototype version of an Electronic Energy Balance Log or eLog. eLog is a computer-assisted system to measure and collect, subjectively (electronically recorded food and activity logs) and objectively (weights of foods/beverages consumed and measurement of movement), the energy balance of subjects in real-time. This instrument is not a tool to assist in diagnosis and/or treatment but rather to assess energy intake and expenditure. This prototype is a handheld personal computer (handheld PC) which has been developed with an NCI SBIR Phase I Contract HHSN261200544010C by Princeton Multimedia Technologies Core (PMT). This software company has developed other Bionutrition-related software specific for the GCRC Bionutrition Cores. The testing of this prototype will be carried out by the GCRC Bionutrition Cores of The Ohio State University and the University of Iowa. This pilot study involves 20 (10 per site) male and/or female subjects, ages 18-65, who will be trained to use eLog to collect real-time food intake and physical activity data. The evaluation will assess the usability of: 1)a scale connected to the handheld PC to capture precise food intake records by weighing foods; 2)entering estimated food intake records on the handheld PC, and 3)monitoring physical activity via a digital activity logger 4)(future testing will be include the use of an accelerometer to evaluate an objective measure of movement).
