Dyspnea and poorer physical performance are conditions that may be related and be present among the elderly. However, few studies have evaluated associations between these variables.
To determine whether there is an association between dyspnea and physical performance among community-dwelling older adults of both sexes (age 60 years and over).
Cross-sectional study conducted in the city of Macapá, state of Amapá, Brazil.
Socioeconomic and health data were collected using a structured form. Frailty syndrome was assessed based on the frailty phenotype proposed by Fried et al. Dyspnea was measured using the modified Medical Research Council (mMRC) scale and physical performance was measured using the Short Physical Performance Battery (SPPB). Data were analyzed using a linear regression model.
A total of 411 subjects (70.15 ± 7.25 years) were evaluated, most of them females (66.4%). It was observed from the mMRC scale that 30.9% (n = 127) of the subjects had some dyspnea symptoms: grade 1 was most frequent. The physical performance score from the SPPB was 9.22 ± 2.01. Higher dyspnea scores were associated with poor physical performance, both in the crude analysis (β = -0.233; P = 0.028) and after adjustment for frailty condition (β = -0.148; P = 0.002) and for the socioeconomic and health variables (age, sex, number of diseases, smoking habit and frailty status) (β = -0.111; P = 0.025).
Higher dyspnea score was independently associated with poor physical performance among community-dwelling older adults.
呼吸困难和身体机能较差是可能相关且在老年人中存在的状况。然而，很少有研究评估这些变量之间的关联。
确定在60岁及以上的社区居住的老年男性和女性中，呼吸困难与身体机能之间是否存在关联。
在巴西阿马帕州马卡帕市进行的横断面研究。
使用结构化表格收集社会经济和健康数据。根据Fried等人提出的衰弱表型评估衰弱综合征。使用改良的医学研究委员会（mMRC）量表测量呼吸困难，使用简短身体机能测试电池（SPPB）测量身体机能。使用线性回归模型分析数据。
共评估了411名受试者（70.15±7.25岁），其中大多数为女性（66.4%）。从mMRC量表观察到，30.9%（n = 127）的受试者有一些呼吸困难症状：1级最为常见。SPPB的身体机能得分为9.22±2.01。在粗分析中（β = -0.233；P = 0.028）以及在调整衰弱状况（β = -0.148；P = 0.002）和社会经济与健康变量（年龄、性别、疾病数量、吸烟习惯和衰弱状态）后（β = -0.111；P = 0.025），较高的呼吸困难评分与较差的身体机能相关。
在社区居住的老年人中，较高的呼吸困难评分与较差的身体机能独立相关。
