摘要
目的探讨低碳水化合物饮食对慢性阻塞性肺疾病患者血气分析及生活质量的影响。方法便利选取2016年11—2017年4月入住上海某三级甲等医院的63例COPD患者为研究对象,前3个月入院患者为试验组(30例),后3个月入院患者为对照组(33例),分别予以低碳水化合物饮食(碳水化合物∶脂肪∶蛋白质=32∶50∶18)和常规饮食(碳水化合物∶脂肪∶蛋白质=55∶27∶18),干预时长为住院期至出院后3个月,观察干预前后两组血气分析指标及生活质量的变化。结果干预前两组的一般情况、血气分析指标和生活质量得分比较,差异无统计学意义(P>0.05)。干预后,试验组pH值、PaO_2及PaCO_2较对照组有显著改善,差异有统计学意义(P<0.05),但两组的剩余碱、SpO_2比较,差异无统计学意义(P>0.05)。出院时及出院后3个月,试验组生活质量显著优于对照组,差异有统计学意义(P<0.05)。结论低碳水化合物饮食有助于改善COPD患者的呼吸状况和生活质量。
Objective To investigate the effect of low-carbohydrate diet on indexes of blood gas analysis and quality of life(QoL)in patients with chronic obstructive pulmonary disease(COPD).Methods A total of 63COPD patients were enrolled.Patients hospitalized in the first 3 months were assigned into the intervention group(n=30), and patients hospitalized in the latter 3months were assigned into the control group(n=33).The intervention group received a low-carbohydrate diet (carbohydrate:fat:protein=32:50:18)while the control group received a regular diet (carbohydrate :fat:protein=55:27:18).The duration of the intervention was from patients in hospital to 3months after discharge.Indexes of blood gas analysis and QoL were compared between two groups.COPD assessment test (CAT)was used to assess patients'QoL.Results Before the intervention,there were no statistically significant differences in demographic factors,indexes of blood gas analysis and CAT scores between two groups(P>0.05). After the intervention,pH,PaO2 and PaCO2 in the experimental group were significantly improved compared with the control group(P<0.05).On the day of discharge and 3months after discharge,the Quality of Life of the experimental group was significantly better than that of the control group,with statistically significant differences(P<0.05). Conclusion Low-carbohydrate diets help to improve the pulmonary function and QoL in COPD patients.
