低血浆总胆固醇水平:可能与住院患者营养不足有关

摘要

Objective To investigate low plasma total cholesterol concentration in hospitalized patients,which is associated with malnourishment.Methods A total of 358 inpatients who were treated in our hospital from January 1 to February 1,2009,were enrolled.The relationships between low plasma total cholesterol (TC) level and other parameters were analyzed.Results Irrespective of women or men,the morbidities of low plasma TC,low plasma albumin,low plasma total proteins,low plasma triglyceride (TG) and low hemoglobin (Hb) levels were highly consistent with the result of subjective global assessment (SGA) (P ＜0.05).Plasma TC concentration was positively correlated with albumin,TG,Hb,lymph cells number,and body mass index (P＜0.05).TC levels were different between men and women (P ＜0.0001).Meanwhile,low plasma TC level was not correlated with age,but it was correlated with total parenteral nutrition.Conclusion Low plasma TC concentration may relate to malnourished hospitalized patients.%目的 探讨低血浆总胆固醇水平是否是评价住院患者营养不足的指标.方法 选取358例2009年1月1日～2月1日在我院住院的患者,分析血浆总胆固醇(TC)水平与其他营养指标的关系及其影响因素.结果 无论男性、女性,血浆TC、白蛋白(ALB)、总蛋白(TP)、甘油三酯(TG)和血红蛋白(Hb)水平与主观全面评定(SGA)结果高度一致(P＜0.05);相关分析显示TC与ALB、TG、Hb、淋巴细胞绝对值(Ly#)、体重指数(BMI)高度相关(P＜0.05),而与血钾(K)、血肌酐(Scr)和TP无相关性(P＞0.05),不同性别TC水平差异具有显著性(P＜0.0001);TC与饮食摄入方式和性别有关,而与年龄无关.单纯肠外营养方式比单纯经口进食方式和单纯肠内营养方式更容易引起低胆固醇血症.结论 低血浆TC水平可能与住院患者营养不足有关.
