稳定期COPD患者的能量摄入现状及影响因素分析OACSTPCD

Objective To investigate the energy intake of patients with stable chronic obstructive pulmonary disease(COPD)and analyze its influencing factors.Methods COPD patients in respiratory medicine department of a community health service center included in a tertiary hospital in Beijing and its medical consortium were investigated using a General Information Questionnaire and a 3×24 h Dietary Review Questionnaire.The dietary intake data were processed by nutrition calculation software to calculate the average daily energy intake of the patients.Univariate and multivariate logistic regression analysis were performed to analyze the influencing factors of substandard energy intake in patients with stable COPD.Results(1)Among the 130 patients with stable COPD,50.8%achieved the recommended standard for energy intake,while 29.2%had lower energy intake than the recommended standard,and 20.0%had higher energy intake.Only 36.9%of patients met recommended protein standard,while 58.5%were below it and 4.6%exceeded it.For fat intake,38.5%of patients met the standard,11.5%were below,and 50.0%surpassed the recommended guideline.Carbohydrate ratio followed a similar pattern,with 39.2%of patients within the standard,35.4%below,and 25.4%above the recommended level.(2)Energy intake was related to factors incuding sex,whether single,monthly income level,number of daily meals and the influence of the disease.Conclusion The energy intake of 49.2%of the patients with stable COPD does not meet the recommended standard.The proportion of protein energy supply lower than the recommended standard is 58.5%,and that of fat energy supply higher than the the recommended standard 50.0%,which need to be improved.Being female,being single,having low monthly income,consuming 2 meals a day,and being affected by the disease are factors that place patients at high risk of inadequate energy intake.An individualized dietary intervention may help address inadequate energy intake when considering all risk factors.
