概括

部分尺寸和MyFitnessPal (MFP) 被评估为饮食摄入的准确性. MFP显示能量摄入量相当于称重食品,而PortionSize需要更新以获得更好的准确性.

科学领域:

营养科学营养科学
饮食评估技术饮食评估技术
医疗信息学医疗信息学

背景情况:

PortionSize提供实时的饮食摄入反,但需要在实验室环境中验证.
MyFitnessPal (MFP) 是一个流行的饮食应用程序,但其基于实验室的准确性尚未研究.
评估数字工具对于准确的饮食摄入量评估至关重要.

研究的目的:

在实验室中验证PortionSize和MFP与体重食物摄入量 (WB) 相比.
为了比较PortionSize和MFP之间的准确性和错误.
评估用户对这两种应用程序的可用性,满意度和偏好.

主要方法:

一项随机交叉研究,在实验室环境中与43名参与者进行了随机交叉研究.
部分大小和MFP摄入量估计与预计的餐 (WB) 的比较.
统计分析包括对等性的t测试和对效应大小的Cohen d.

主要成果:

份量大小低估了能量 (13.3%) 和份量大小 (14.0%),无法与WB相等.
多重塑料板高估了7.0%的能量,但相当于WB (P=0.04).
在可用性方面没有显著的差异;MFP更容易使用,受试者更喜欢.

结论:

PortionSize需要在能量估计和临床实用性可用性方面进行改进.
部分尺寸显示用于跟踪食物组和营养素,但不是能量摄入量.
在这项研究中,与PortionSize相比,MFP在能量摄入量测量方面表现更好.

Uncertainty in Measurement: Reading Instruments

Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...
