ABSTRACT

Background

Sarcopenia has a high prevalence in older adults and is associated with chronic aggravations to health, so therefore it is important to identify older adults who are affected by sarcopenia in order to establish preventative strategies or early interventions.

Objective

To estimate the prevalence of probable sarcopenia and verify its association with cognitive impairment, fear of falling, depressive symptoms and health self-perception in community-dwelling older adults.

Methods

A cross-sectional study with simple random sampling including 306 older adults of both genders. The outcome variable was probable sarcopenia evaluated by the Five times sit-to-stand test (5XSST) considering probable sarcopenia when the measured time was > 15 seconds, following the recommendation of the European Working Group on Sarcopenia in Older People. The predictor variables were cognitive impairment, fear of falling, depressive symptoms and self-perception of health. Multivariate Logistic Regression was performed to verify associations between the variables.

Results

The prevalence of probable sarcopenia was 50.00%. The older adults had significantly higher chances of presenting probable sarcopenia when displaying cognitive impairment (OR 2.49; 95%CI 1.46–4.24), fear of falls (OR 4.23; 95%CI 2.51–7.12), depressive symptoms (OR 2.20; 95%CI 1.32–3.67), poor (OR 2.48; 95%CI 1.19–5.16) and fair self-perception of health (OR 2.11; 95%CI 1.22–3.63) when compared to those who did not have the same conditions.

Conclusion

The prevalence of probable sarcopenia in this study was 50.00%, and was associated with the presence of depressive symptoms, cognitive impairment, fear of falls and negative self-perception of health.

与社区老年人可能的肌肉减少症相关的认知和行为因素

摘要

背景

肌肉减少症在老年人中的患病率很高，并且与健康的慢性恶化有关，因此识别受肌肉减少症影响的老年人以制定预防策略或早期干预措施非常重要。

客观的

估计可能的肌肉减少症的患病率，并验证其与社区老年人的认知障碍、对跌倒的恐惧、抑郁症状和健康自我认知的关系。

方法

一项简单随机抽样的横断面研究，包括 306 名男女老年人。结果变量是根据欧洲老年人肌肉减少症工作组的建议，在测量时间> 15 秒时考虑可能的肌肉减少症，通过五次坐站试验 (5XSST) 评估可能的肌肉减少症。预测变量是认知障碍、对跌倒的恐惧、抑郁症状和对健康的自我认知。执行多元逻辑回归以验证变量之间的关联。

结果

可能的肌肉减少症的患病率为 50.00%。老年人在表现出认知障碍（OR 2.49；95%CI 1.46-4.24）、害怕跌倒（OR 4.23；95%CI 2.51-7.12）、抑郁症状（OR 2.20；95%）时出现可能的肌肉减少症的机会显着增加与没有相同条件的人相比，CI 1.32–3.67）、差（OR 2.48；95%CI 1.19–5.16）和公平的健康自我认知（OR 2.11；95%CI 1.22–3.63）。

结论

在这项研究中，可能的肌肉减少症的患病率为 50.00%，并且与抑郁症状、认知障碍、跌倒恐惧和对健康的负面自我认知有关。
