【摘要】：目的研究哮喘患者膳食营养素摄入与肺功能的相关性。方法选取哮喘患者130例,健康对照组60例。采用半定量食物频率问卷调查哮喘患者及健康对照组近3个月饮食中14种营养素摄入量并检测肺功能及体重指数,分析哮喘患者膳食营养素的摄入与肺功能的相关性。结果哮喘患者的年龄、体重、体重指数均高于健康对照组(P0.05)。重度持续发作组患者1 s用力呼气容积(FEV1)、用力肺活量高于健康对照组及间歇发作、轻度持续发作、中度持续发作组(P0.05)。膳食因素中,摄入总能量、蛋白质、碳水化合物、钙、镁、磷、铁、锌、维生素C、视黄醇,健康对照组与重度持续发作组相比无统计学差异(P0.05)。脂肪、纤维、钠、钾,健康对照组与重度持续发作组相比,具有统计学差异(P0.05)。脂肪与FEV1、用力肺活量(FVC)、比率呈负相关;纤维与FEV1、FVC比率呈正相关。结论重度哮喘患者饮食具有高脂肪、高钠、低钾、低纤维的特点;脂肪、纤维与哮喘患者的肺功能有关;纤维对哮喘患者肺功能具有保护性作用。
[Abstract]:Objective to study the relationship between dietary nutrient intake and lung function in asthmatic patients.Methods 130 asthmatic patients and 60 healthy controls were selected.A semi-quantitative food frequency questionnaire was used to investigate the intake of 14 nutrients in the diet of asthmatic patients and healthy controls in the past 3 months. The pulmonary function and body mass index (BMI) were measured to analyze the correlation between dietary nutrient intake and lung function in asthmatic patients.Results the age, body weight and body mass index of asthmatic patients were higher than that of healthy control group (P 0.05).The forced expiratory volume (FEV1) in the severe persistent attack group was higher than that in the healthy control group and intermittent attack group (P 0.05).Dietary factors, total energy, protein, carbohydrate, calcium, magnesium, phosphorus, iron, zinc, vitamin C, retinol, there was no significant difference between the healthy control group and severe persistent attack group (P 0.05).Fat, fiber, sodium, potassium, healthy control group and severe persistent attack group, there was statistical difference (P 0.05).There was a negative correlation between fat and FEV _ 1, forced vital capacity and FV _ (C) ratio, and a positive correlation between fiber and FEV _ 1 / FVC ratio.Conclusion the diet of patients with severe asthma has the characteristics of high fat, high sodium, low potassium and low fiber, fat and fiber are related to the lung function of asthmatic patients, and fiber has protective effect on lung function of asthmatic patients.
