摘要
目的:本研究旨在探讨不同性别社区居住老年人膳食多样性与身体虚弱之间的关系。设计:横断面研究。地点:日本兵库县西宫市。参与者:随机选择4996名居住在西宫市的65岁及以上的社区老年人。测量方法:调查问卷通过邮件分发。衰弱评分采用5项衰弱筛查指数进行评定。膳食多样性的评估使用膳食多样性评分为一般老年日本人口开发。结果:共有2764名年龄≥65岁的社区居民参与了问卷调查。在排除缺失数据后，1780名参与者被纳入研究分析。老年独居男性的衰弱评分明显高于老年同居男性(P < 0.001)。独居老年男性的饮食多样性评分显著低于同居老年男性(P < 0.001)。然而，在老年妇女中，独自生活和与人一起生活之间的虚弱和饮食多样性评分没有差异(P = 0.360和P = 0.265)。在多变量回归分析中，饮食多样性评分与独居者虚弱评分之间的相关性(β= -0。271, P = 0.011)比与人同居的老年男性更强(β= -0.131, P = 0.045)。与与人同居的老年妇女相比，单独生活的老年妇女饮食多样性与虚弱之间存在类似的关联(β -0.114, P = 0.002;β -0.088, P = 0.012)。结论:独居的老年男性有较高的衰弱评分和较低的饮食多样性。在老年男性和老年女性中，饮食多样性与身体虚弱之间的联系因生活安排而异。
Associations between Dietary Variety and Frailty in Community-Dwelling Older People Who Live Alone: Gender Differences.
Objectives: This study aimed to investigate the influences of living arrangements on the association between dietary variety and frailty by gender in community-dwelling older people.
Design: A cross-sectional study.
Setting: Nishinomiya city, Hyogo prefecture, Japan.
Participants: A total of 4,996 randomly selected community-dwelling older people aged 65 years and older and living in Nishinomiya City.
Measurements: Survey questionnaires were distributed via mail. The frailty score was evaluated by the 5-item frailty screening index. Dietary variety was assessed using the dietary variety score developed for the general older Japanese population.
Results: A total of 2,764 community-dwelling participants aged ≥ 65 years responded to the questionnaires. After excluding missing data, 1,780 participants were included in the study analysis. The frailty scores in older men living alone were significantly higher than those in older men living with someone (P < 0.001). The dietary variety scores in older men living alone were significantly lower than those in older men living with someone (P < 0.001). However, differences in the frailty and dietary variety scores between living alone and living with someone were not were observed in older women (P = 0.360 and P = 0.265, respectively). In the multivariable regression analysis, the associations between dietary variety score and frailty score in living alone (β= -0. 271, P = 0.011) were stronger than those in living with someone in the case of older men (β= -0.131, P = 0.045). Similar associations between dietary variety and frailty were presented in older women living alone than in those living with someone (β -0.114, P = 0.002; β -0.088, P = 0.012, respectively).
Conclusions: Older men who live alone had higher frailty score and lower dietary variety. The associations between dietary variety and frailty were different according to living arrangements in both older men and older women.
期刊介绍：
The Journal of Frailty & Aging is a peer-reviewed international journal aimed at presenting articles that are related to research in the area of aging and age-related (sub)clinical conditions. In particular, the journal publishes high-quality papers describing and discussing social, biological, and clinical features underlying the onset and development of frailty in older persons. The Journal of Frailty & Aging is composed by five different sections: - Biology of frailty and aging In this section, the journal presents reports from preclinical studies and experiences focused at identifying, describing, and understanding the subclinical pathophysiological mechanisms at the basis of frailty and aging. - Physical frailty and age-related body composition modifications Studies exploring the physical and functional components of frailty are contained in this section. Moreover, since body composition plays a major role in determining physical frailty and, at the same time, represents the most evident feature of the aging process, special attention is given to studies focused on sarcopenia and obesity at older age. - Neurosciences of frailty and aging The section presents results from studies exploring the cognitive and neurological aspects of frailty and age-related conditions. In particular, papers on neurodegenerative conditions of advanced age are welcomed. - Frailty and aging in clinical practice and public health This journal’s section is devoted at presenting studies on clinical issues of frailty and age-related conditions. This multidisciplinary section particularly welcomes reports from clinicians coming from different backgrounds and specialties dealing with the heterogeneous clinical manifestations of advanced age. Moreover, this part of the journal also contains reports on frailty- and age-related social and public health issues. - Clinical trials and therapeutics This final section contains all the manuscripts presenting data on (pharmacological and non-pharmacological) interventions aimed at preventing, delaying, or treating frailty and age-related conditions.The Journal of Frailty & Aging is a quarterly publication of original papers, review articles, case reports, controversies, letters to the Editor, and book reviews. Manuscripts will be evaluated by the editorial staff and, if suitable, by expert reviewers assigned by the editors. The journal particularly welcomes papers by researchers from different backgrounds and specialities who may want to share their views and experiences on the common themes of frailty and aging.The abstracting and indexing of the Journal of Frailty & Aging is covered by MEDLINE (approval by the National Library of Medicine in February 2016).
