- 肝病学 肝病学是一种肝病学.
- 遗传学 是一个遗传学.
背景情况:
- 基础代谢率 (BMR) 和非酒精性脂肪肝 (NAFLD) 之间的关系需要进一步阐明,特别是关于性别特异性的变化.
- 针对特定人群的分析对于了解BMR对NAFLD患病率的影响至关重要.
研究的目的:
- 为了研究BMR和NAFLD在不同人群中的关联.
- 探索BMR-NAFLD关系中的潜在性别差异.
- 使用遗传数据确定BMR和NAFLD之间的因果关系.
主要方法:
- 对30845名中国人和5019名美国成年人的健康检查数据的分析 (NHANES 2017-2020).
- 使用Mifflin-St Jeor方程和统计分析,包括后勤回归和限制立方线 (RCS) 的BMR估计.
- 两个样本的孟德尔随机化 (MR) 研究利用全基因组关联研究 (GWAS) 数据对欧洲人口的BMR和NAFLD.
主要成果:
- 在中国人群中观察到较高的BMR四分位数与NAFLD的几率增加之间存在显著的,剂量依赖的关联.
- 在BMR-NAFLD关联中的性别差异在中国队列中显著 (P的相互作用<0.05),但在美国队列中没有.
- 两个样本的MR证实了BMR对NAFLD的因果关系,赔率比 (OR) 为1.59 (95%CI:1.24-2.03).

Metabolic Rate
1.3K
The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.

Mechanistic Models: Compartment Models in Individual and Population Analysis
305
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...
