概括
全球饮食质量评分 (GDQS) 应用程序使用3D立方体或花粉来估计份量,相当于衡量食物记录来评估饮食质量. 这些简化工具为频繁的饮食质量评估提供了经过验证的方法.
科学领域:
- 营养科学 营养科学
- 饮食评估方法 饮食评估方法
- 公共卫生 营养 公共卫生 营养
背景情况:
- 全球饮食质量评分 (GDQS) 对于评估饮食质量至关重要.
- 标准化部分大小估计对于准确的GDQS数据收集至关重要.
- 该GDQS应用程序使用3D立方体,用玩粉作为替代方案.
研究的目的:
- 为了验证GDQS应用程序使用3D立方体和面与称重食品记录 (WFRs) 相比.
- 评估通过app (立方体/花粉) 和WFRs获得的GDQS测量的等价性.
- 评估在分类个体中存在饮食质量差的风险的协议.
主要方法:
- 一个重复测量设计涉及170名18岁以上的参与者.
- 参与者使用WFR和GDQS应用程序用立方体和粉末估计了部分大小.
- 测试的同等性是用对对的两种单面t测试 (TOST) 测试,分差为2.5分;一致性用卡帕系数量化.
主要成果:
- 来自立方体和花粉的GDQS测量相当于在2.5点边际内的WFR (p=0.006为立方体,p<0.001为花粉).
- 立方体 (κ=0.5685) 和花粉 (κ=0.5843) 在识别饮食质量差的风险人群时,都与WFR表现出中度一致.
- 在25个食品组中,有22个食品组存在实质性的一致性,其中液态油具有最低的一致性 (κ=0.059).
结论:
- 无论是使用3D立方体还是玩粉,GDQS应用程序都提供与WFR相比相当的饮食质量评估.
- 这些发现支持使用简化,验证的工具进行饮食评估.
- 这有助于更频繁,更容易地对人口饮食质量进行评估.

01:19Testing a Claim about Standard Deviation
2.4K
A complete procedure to test a claim about population standard deviation or population variance is explained here.
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...

01:20Sample Proportion and Population Proportion
5.1K
Collecting samples or responses from an entire population takes significant time and effort, so a researcher collects responses from only a sample of that population. Suppose a study needs to collect information about a specific mobile application. After sample collection, the researcher analyzes the data and discovers that most individuals in the sample use that specific mobile application. The sample proportion measures the number of individuals in a sample who either use or don't use the...
