Impaired respiratory muscle strength has been associated with some geriatric syndromes. However, no studies have previously evaluated the relationship between respiratory muscle strength and dynapenic abdominal obesity. This study aimed to analyze whether there is an association between respiratory muscle strength and abdominal obesity, dynapenia and dynapenic abdominal obesity (DAO) in community-dwelling older adults.
Cross-sectional study conducted with community-dwelling older adults (n=382 / 70.03 ± 7.3 years) from Macapá, Amapá, Brazil. Respiratory muscle strength was assessed by measuring maximal inspiratory and expiratory pressures (MIP and MEP, respectively), using an analog manovacuometry. DAO was defined as the combination of dynapenia (grip strength < 26 kgf for men and < 16 kgf for women) and abdominal obesity (abdominal circumference > 102 cm for men and > 88 cm for women). We performed descriptive and inferential statistical analyses using the student's -test for independent and related samples and linear regression model.
Older adults with abdominal obesity, dynapenia, and DAO presented lower mean values (obtained and obtained versus predicted; except abdominal obesity versus MIP) for maximal respiratory pressures compared to individuals without these conditions. However, the adjusted analysis only indicated an association between MIP and the following conditions: dynapenia (MIP - β =-0.171; p<0.001), abdominal obesity (MIP - β=0.102; p=0.042), and DAO (MIP - β=-0.101; p=0.028).
Older adults with abdominal obesity, dynapenia, and DAO showed impaired maximal respiratory pressures. The results of the adjusted analysis indicate that inspiratory muscle strength may require greater attention by health professionals aiming at preventing respiratory complications and improving respiratory health care in older people with these conditions.
呼吸肌力量的减弱与一些老年综合征有关。然而，以前没有研究评估过呼吸肌力量与无力性腹部肥胖之间的关系。本研究旨在分析社区居住的老年人的呼吸肌力量与腹部肥胖、无力和无力性腹部肥胖（DAO）之间是否存在关联。
这是一项在巴西阿马帕州马卡帕的社区居住的老年人（n=382 / 70.03 ± 7.3 岁）中进行的横断面研究。使用模拟肺量计测量最大吸气和呼气压力（MIP 和 MEP）来评估呼吸肌力量。DAO 定义为无力（男性握力<26kgf，女性<16kgf）和腹部肥胖（男性腹围>102cm，女性>88cm）的组合。我们使用学生 t 检验进行描述性和推断性统计分析，用于独立和相关样本，并使用线性回归模型。
与没有这些情况的个体相比，有腹部肥胖、无力和 DAO 的老年人的最大呼吸压力的平均值较低（获得和获得与预测值相比；除了腹部肥胖与 MIP 相比）。然而，调整后的分析仅表明 MIP 与以下情况之间存在关联：无力（MIP-β=-0.171；p<0.001）、腹部肥胖（MIP-β=0.102；p=0.042）和 DAO（MIP-β=-0.101；p=0.028）。
有腹部肥胖、无力和 DAO 的老年人表现出最大呼吸压力受损。调整后的分析结果表明，吸气肌力量可能需要更引起卫生专业人员的关注，旨在预防这些人群的呼吸并发症，并改善老年人的呼吸健康护理。
