Abstract

Objectives

The present study examined the associations between the dietary intake of polyunsaturated fatty acids (PUFAs), physical function, and the prevalence of sarcopenia in Italian community-dwelling older adults.

Design

Cross-sectional study.

Setting

Unconventional settings across Italy (e.g., exhibitions, health promotion campaigns).

Participants

Older adults (65+ years) who provided a written informed consent.

Methods

Physical function was evaluated according to isometric handgrip strength (IHG) and 5-time sit-to-stand (5STS) performances. Muscle power parameters were estimated based on 5STS values. Sarcopenia was operationalized according to the presence of low physical function (IHG or 5STS) plus low appendicular skeletal muscle mass (ASM), estimated according to calf circumference. A 12-item food questionary was used to estimate the dietary intake of PUFAs, which included omega-3 (α-linolenic acid, eicosapentaenoic acid, docosahexaenoic acid) and omega-6 fatty acids.

Results

Multiple linear regression results indicate negative and significant associations between the dietary intake of α-linolenic acid and muscle power, and between docosahexaenoic acid consumption and ASM. No significant associations were found between PUFAs-related variables and sarcopenia.

Conclusions

Results of the present study indicate that PUFAs-related variables were negatively and significantly associated with physical function and body composition in older adults. Nevertheless, no significant associations were found with sarcopenia. These findings suggest that a more detailed analysis of covariates should be conducted in future investigations that aim to examine the associations between the dietary intake of PUFAs and sarcopenia-related parameters.

社区老年人饮食摄入多不饱和脂肪酸、身体机能和肌肉减少症之间的横断面关联

目的：本研究探讨了意大利社区老年人饮食摄入多不饱和脂肪酸（PUFAs）、身体功能和肌肉减少症患病率之间的关系。DesignCross-sectional研究。意大利各地的非传统环境（例如，展览，健康促进活动）。参与者为提供书面知情同意书的成年人（65岁以上）。方法采用等长握力（IHG）和5次坐立（5STS）评价身体机能。根据5STS值估计肌力参数。骨骼肌减少症是根据存在低物理功能（IHG或5STS）加上低阑尾骨骼肌质量（ASM），根据小腿围估计。研究人员使用了一份包含12个条目的食物问卷来评估膳食中PUFAs的摄入量，其中包括omega-3 （α-亚麻酸、二十碳五烯酸、二十二碳六烯酸）和omega-6脂肪酸。结果多元线性回归结果显示，α-亚麻酸摄入量与肌肉力量呈显著负相关，二十二碳六烯酸摄入量与肌肉力量呈显著负相关。pufas相关变量与肌肉减少症之间未发现显著关联。结论pufas相关变量与老年人身体机能和身体成分呈显著负相关。然而，没有发现与肌肉减少症有显著关联。这些发现表明，在未来的研究中，应该对协变量进行更详细的分析，以研究膳食摄入PUFAs与肌肉减少症相关参数之间的关系。

期刊介绍： There is increasing scientific and clinical interest in the interactions of nutrition and health as part of the aging process. This interest is due to the important role that nutrition plays throughout the life span. This role affects the growth and development of the body during childhood, affects the risk of acute and chronic diseases, the maintenance of physiological processes and the biological process of aging. A major aim of "The Journal of Nutrition, Health & Aging" is to contribute to the improvement of knowledge regarding the relationships between nutrition and the aging process from birth to old age.
