105例呼吸科门诊老年男性COPD患者营养状态的分析

Analysis of nutritional status of 105 cases of elderly male COPD patients in respiratory department outpatient

目的本研究的目的是分析老年男性COPD患者营养不良的患病率、营养状态,以及与营养状况相关的预测因子。方法对105名在我院老年呼吸科门诊就诊的老年COPD男性患者(年龄】60岁)进行横断面研究,进行机体组成的测量、营养状态和呼吸功能的评估。结果研究结果表明,105名入选的老年COPD患者47.6%体重正常,38.1%超重,14.3%为低体重。41.9%存在非脂肪组织指数(FFMI)减少。严重的老年男性COPD患者(Ⅲ、Ⅳ级)营养不良发生率为52.4%,明显高于轻中度的老年男性COPD患者(Ⅰ、Ⅱ级)营养不良发生率(26.2%)(P【0.05)。血浆中维生素A浓度,呼气峰流速PEF和握力是身体质量指数(BMI)的预测因子(R2=0.190,P【0.001)。血浆中维生素A和第一秒用力呼气容积是非脂肪质量指数(FFMI)的预测因子(R2=0.082,P=0.007)。身体质量指数(BMI)是呼吸因素的预测因子,与FEV1%预计值相关(R2=0.052,P=0.011)。结论我们的研究显示早期预测老年男性COPD营养不良,并进行合适的营养治疗及护理是非常有必要的。

Objective This study aimed to determine the prevalence rate of malnutrition and nutritional status and also factors associated with nutritional status. Methods This study had an cross-sectional experimental design in which 105 old male patients with COPD from our hospital respiratory clinic.Measure body composition and assess nutritional status and respiratory function.Results The results of the study showed that 47.6% of 105 old male patients were normal weight,38.1% of them were overweight,and 14.3% were low weight.malnutrition was more prevalent( 52.4% ) in the subjects with severe stages of COPD as compared to mild and moderate COPD stages( 26.2% ) ( P < 0.05) .Plasma vitamin A,peak expiratory flow( PEF) ,and handgrip were the predictors for body mass index( BMI) ( R2 = 0.190,P < 0. 001) .Plasma vitamin A and force expiratory volume in one second( FEV1) were the predictors of FFMI( R2 = 0.082,P = 0.007) .BMI was the predictor of respiratory factors,that is,FEV1% predicted( R2 = 0.052,P = 0.011) .Conclusions Our findings show that there is a need to identify malnourished COPD patients for an appropriate nutrition intervention.
