In healthy elderly and adults, lower physical activity level in daily life has been associated with lower socio-economic level and non-Caucasian race. The objective of this study was to determine if this is also applicable in chronic obstructive pulmonary disease (COPD) by comparing physical activity levels in daily life in stable patients from two countries (Austria and Brazil) with different socio-economic and ethnic characteristics.
Physical activity in daily life was objectively assessed in 40 Austrian and 40 Brazilian COPD patients. Groups were matched for age, gender, body mass index, disease severity, smoking history, presence of concomitant heart disease, lung function, dyspnea and functional exercise capacity. In addition, climatic conditions were similar during the period of data collection in the two groups.
In comparison to Brazilian patients, Austrian patients had a significantly lower walking time (p=0.04), higher sitting time (p=0.02) and lower movement intensity (p=0.0001). The proportion of patients who did not reach an average of 30min of walking per day was 48% in the Austrian group and 23% in the Brazilian group.
Austrian patients with COPD showed a significantly lower daily physical activity level in comparison to matched Brazilian patients. Socio-economic and ethnic factors appear to influence stable COPD patients differently than described in previous studies including healthy subjects.
在健康老年人和成年人中，日常生活中较低的身体活动水平与较低的社会经济水平和非白种人种族有关。本研究的目的是通过比较来自两个具有不同社会经济和种族特征的国家（奥地利和巴西）的稳定期慢性阻塞性肺疾病（COPD）患者的日常生活身体活动水平，来确定这是否也适用于COPD患者。
对40名奥地利和40名巴西COPD患者的日常生活身体活动进行客观评估。两组在年龄、性别、体重指数、疾病严重程度、吸烟史、合并心脏病情况、肺功能、呼吸困难和功能运动能力方面进行匹配。此外，两组在数据收集期间的气候条件相似。
与巴西患者相比,奥地利患者的步行时间显著缩短（p=0.04），久坐时间更长（p=0.02），运动强度更低（p=0.0001）。奥地利组中每天步行时间未达到平均30分钟的患者比例为48%，而巴西组为23%。
与匹配的巴西患者相比，奥地利COPD患者的日常身体活动水平显著较低。社会经济和种族因素对稳定期COPD患者的影响似乎与先前包括健康受试者在内的研究中所描述的不同。
