概括
在城市贫民窟,儿童发展迟缓的过渡是常见的. 诸如男性性别,粮食不安全和种族等因素会影响迟缓的严重程度,强调需要有针对性的干预措施.
科学领域:
- 儿科 儿科 儿科
- 公共卫生 公共卫生
- 营养科学 营养科学
背景情况:
- 儿童发育迟缓在低收入和中等收入国家普遍存在,特别是在城市贫民窟.
- 有限的研究存在于城市贫民窟环境中的儿童缩过渡和相关因素.
- 这项研究的重点是描述在内罗毕贫民窟的儿童中发育不良状态的转变及其决定因素.
研究的目的:
- 分析0-3岁儿童不同衰老状态 (正常,边缘,中度,严重衰老) 之间的过渡.
- 确定与这些衰退过渡相关的社会人口和环境因素.
- 为减少城市贫民窟人口中儿童发育迟缓提供特定背景干预信息.
主要方法:
- 利用了来自内罗毕城市和人口监测系统 (NUHDSS) 和嵌套疫苗接种研究 (2010-2014) 的数据.
- 包括692名0-3岁的儿童,拥有完整的人类测量和社会人口统计数据.
- 采用高度对年龄的Z分数 (HAZ) 来定义衰减类别和连续的多状态模型来分析过渡和相关因素.

01:23Mechanistic Models: Compartment Models in Individual and Population Analysis
41
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

01:52Regression Toward the Mean
6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

12.0K
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...
