Background

Understanding the impacts of increased adiposity on postural control and cognitive deficits in adults is critical for health practitioners in recommending or prescribing effective weight loss regimens. Despite prior work in this area, the knowledge of increased adiposity impacts on postural control and cognitive deficits in older adults (OAs) is still limited.

Research question

The purposes of the current study were: (a) to assess the relationship between postural measures and adiposity measures by using regression model analyses and, (b) to examine the impacts of increased adiposity and age on cognitive performance.

Methods

A total of thirty (30) individuals aged 60+ years participated in the study. Participants were classified into three groups based upon their BMI scores at the onset of the study. The normal weight (NW) (BMI: 18.5–24.9 kg/m²), the overweight (OW) (BMI: 25–29.9 kg/m²), and the obese (OB) groups (BMI: 30−40 kg/m²) each had five females and five males. Participants were required to perform two test sessions: (1) anthropometry assessment and body composition scanning; and (2) evaluation of plantar tactile function, postural control, and cognitive function.

Results

Overall, our findings indicate that increased adiposity in OAs is associated with declines in both cognitive function and postural control.

Significance

Our data also indicate that measures such as BMI and abdominal fat mass amounts/ratios offer the best insight to the impact of adiposity on cognitive function and postural control measures. However, further work is still needed to clarify the mechanistic links between adiposity and cognitive-postural deficits.

肥胖对老年人姿势控制和认知的影响。

背景

了解肥胖症对成年人的姿势控制和认知缺陷的影响，对于健康从业者在推荐或制定有效的减肥方案时至关重要。尽管已经在该领域进行了先前的工作，但是关于肥胖对老年人的姿势控制和认知缺陷的影响增加的知识仍然有限。

研究问题

本研究的目的是：（a）通过使用回归模型分析来评估姿势测量与肥胖测量之间的关系，以及（b）研究肥胖和年龄增加对认知能力的影响。

方法

共有三十（30）位年龄在60岁以上的人参加了这项研究。在研究开始时，根据参与者的BMI评分将其分为三组。正常体重（NW）（BMI：18.5–24.9 kg / m ²），超重（OW）（BMI：25–29.9 kg / m ²）和肥胖（OB）组（BMI：30−40 kg / m ²）各有五位女性和五位男性。要求参与者进行两个测试会议：（1）人体测量学评估和身体成分扫描；（2）足底触觉功能，姿势控制和认知功能的评估。

结果

总体而言，我们的研究结果表明，OAs中肥胖的增加与认知功能和姿势控制的下降有关。

意义

我们的数据还表明，诸如BMI和腹部脂肪量/比率之类的措施可提供最佳见解，以了解肥胖对认知功能和姿势控制措施的影响。但是，仍然需要进一步的工作来阐明肥胖与认知姿势缺陷之间的机械联系。
