概括
仅仅是中上臂周长 (MUAC) 不足以识别被浪费的菲律宾儿童. 将MUAC与体重对年龄z-score (WAZ) 结合起来,可显著提高中度和严重衰减的检测准确度,有助于及时干预.
科学领域:
- 公共卫生 营养 公共卫生 营养
- 儿童营养不良问题
- 诊断准确性研究 诊断准确性研究
背景情况:
- 准确的人类测量,如体重与身高的z-score (WHZ) 对于识别儿童消耗至关重要,但在资源有限的环境中具有挑战性.
- 中上臂周长 (MUAC) 是一个更简单的选工具,但仅仅在识别浪费时的有效性需要进一步评估.
- 现有的MUAC切断可能导致低诊断和延迟治疗浪费的儿童,影响健康结果.
研究的目的:
- 用WHZ作为标准标准,确定在6-59个月的菲律宾儿童中检测儿童消耗的最佳案例定义.
- 为了评估各种MUAC截止值和联合MUAC-weight-for-age z-score (WAZ) 定义的诊断性能.
主要方法:
- 来自菲律宾的2018-2019年扩展国家营养调查数据的分析 (N=30,522).
- 评估不同MUAC截止值和联合MUAC-WAZ标准对WHZ的诊断准确性 (灵敏度,特异性,AUROC).
- 根据接收器运行特征曲线 (AUROC) 下的最高面积,确定表现最佳的案例定义.
主要成果:
- 目前的MUAC切断在识别严重的 (AUROC:0.558) 和中度的 (AUROC:0.586) 消耗方面表现不佳.
- 最佳的MUAC切线被确定为<13.6cm的严重消耗 (AUROC:0.690) 和14.0cm的中度消耗 (AUROC:0.737).
- 结合WAZ<-2与MUAC切断值 (严重的<11.7厘米,中度的<12.7厘米) 显著改善了诊断准确性 (AUROC:分别为0.800和0.810).
结论:
- 仅仅依靠扩展的MUAC截止值,对于在菲律宾儿童中根据WHZ标准检测浪费,没有足够的改善.
- 将WAZ与MUAC相结合,提供了一种更准确,更灵敏的方法来识别中度和重度丧的儿童.
- 拟议的WAZ和MUAC联合病例定义需要进一步调查,以便在菲律宾急性营养不良综合管理计划中切实实施.

Midrange
3.5K
A somewhat easy to compute quantitative estimate of a data set’s central tendency is its midrange, which is defined as the mean of the minimum and maximum values of an ordered data set.
Simply put, the midrange is half of the data set’s range. Similar to the mean, the midrange is sensitive to the extreme values and hence the prospective outliers. However, unlike the mean, the midrange is not sensitive to all the values of the data set that lie in the middle. Thus, it is prone to...

Anorexia Nervosa

Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.
