An insufficient intake of magnesium may be associated with the development of chronic obstructive pulmonary disease (COPD). We aimed to determine the relationship between health related quality of life (QoL), anthropometric indices and nutritional status with dietary magnesium intake in COPD patients. Sixty-one COPD patients participated in this cross-sectional study. QoL and nutritional status were assessed. Furthermore, body composition, calf circumference, and muscle strength were measured; equations were used to calculate fat-free mass index, body mass index, and muscle mass value. Dietary magnesium intake was assessed by three 24-hours recalls and magnesium intake was categorized as ≤ 188.08 mg/day (A group) and > 188.08 mg/day (B group). The χ, independent-sample t-test and Mann-Whitney test were used for statistical analysis. The p values less than 0.05 were considered significant. Of QoL assessments the total and impact mean scores of St. George's respiratory questionnaire in the B group were significantly lower than the means of the A group (p value = 0.007 and 0.005, respectively). The instrumental activity of daily living score was significantly improved in patients with higher consumption of dietary magnesium (p = 0.02). Participants had a significantly lower mean score of patient-generated subjective global assessment in the B group compared to the A group (p = 0.003). Higher intake of dietary magnesium can lead to improve QoL and nutrition status.
镁摄入不足可能与慢性阻塞性肺疾病（COPD）的发生有关。我们旨在确定COPD患者的健康相关生活质量（QoL）、人体测量指标和营养状况与膳食镁摄入量之间的关系。61名COPD患者参与了这项横断面研究。对QoL和营养状况进行了评估。此外，测量了身体成分、小腿围和肌肉力量；使用公式计算无脂肪质量指数、体重指数和肌肉质量值。通过三次24小时饮食回顾评估膳食镁摄入量，并将镁摄入量分为≤188.08毫克/天（A组）和>188.08毫克/天（B组）。采用χ检验、独立样本t检验和曼-惠特尼检验进行统计分析。p值小于0.05被认为具有统计学意义。在QoL评估中，B组圣乔治呼吸问卷的总分和影响平均分显著低于A组（p值分别为0.007和0.005）。膳食镁摄入量较高的患者日常生活活动能力得分显著提高（p = 0.02）。与A组相比，B组患者自我主观全面评定的平均分显著更低（p = 0.003）。较高的膳食镁摄入量可改善QoL和营养状况。
