概括

这项研究验证了营养流行病学食品频率问卷 (FFQ). 该FFQ证明了足够的有效性和可重复性,用于评估丹麦队列的饮食摄入量.

科学领域:

营养流行病学营养流行病学
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:

食物频率问卷 (FFQ) 在营养流行病学中被广泛使用,用于评估习惯性饮食摄入量.
饮食,癌症和下一代健康 (DCH-NG) 队列研究需要经过验证的FFQ进行准确的饮食评估.
评估FFQ的有效性和可重复性对于可靠的流行病学研究至关重要.

研究的目的:

评估DCH-NG队列中使用的FFQ的相对有效性和可重复性.
为了确定FFQ在估计能量,营养和食物组摄入量的准确性.
确认FFQ适合用于大规模流行病学研究.

主要方法:

一组415名丹麦成年人 (18-67岁) 参与.
通过比较FFQ基线 (FFQ_基线) 与三个24小时饮食回忆 (24-HDR) 来评估相对有效性.
通过比较FFQ_基线与12个月后给出的FFQ (FFQ_12个月) 来评估可重复性. 使用了斯皮尔曼的相关性,布兰德-阿尔特曼分析和交叉分类. 营养素摄入量经过能量调整.

主要成果:

在FFQ_基线和24-HDR之间的相关系数为0.18-0.58的能量和能量调整的营养素.
在FFQ_基线和24-HDR之间,参与者被分类到同一个四分位数的比例为28-47%.
在FFQ<12个月>和FFQ<基线>之间的相关系数在0.52-0.88之间,其中43%-69%的参与者属于同一四分位数.

结论:

在DCH-NG队列中,FFQ证明了令人满意的相对有效性和可重复性.
该FFQ适用于根据能量,营养素和食物组摄入量对个人进行排名.
这种经过验证的FFQ可以可靠地用于调查饮食与疾病关系的流行病学研究.

Longitudinal Research

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessment of the Gastrointestinal System II: Health Perception Pattern

Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
