Abstract

BackgroundAlthough there have been studies on the association between nutritional status and functional limitations, there were few studies on Asian centenarians in community. Therefore, this study aims to identify associations between nutritional status and functional limitations among centenarians in China.MethodsThis cross-sectional study was conducted with the data from the China Hainan Centenarian Cohort Study. These data ultimately included basic characteristics, hematologic indicators, and chronic disease status for 1,002 centenarians. The nutritional status was evaluated using the Mini Nutritional Assessment Short-Form scale. The functional limitations were assessed using the activities of daily living (ADL) scale, namely Barthel Index and Lawton Scale. The association between nutritional status and ADL was assessed using multivariate logistic regression models.ResultsIn this study, the prevalence of malnutrition was 20.8 % among centenarians, basic ADL (BADL) limitation was 28.6 %, and instrumental ADL (IADL) limitation was 64.7 %. As the nutritional status deteriorated, the risk of ADL limitations increased in total population (BADL limitation: OR = 17.060, 95 % CI: 8.093-35.964; IADL limitation: OR = 11.221, 95 % CI: 5.853-21.511; p for trend < 0.001). Similar results were found in both men and women after stratifying sex but were more prominent in women.ConclusionsMalnutrition is associated with functional limitations among centenarians in China and more pronounced among women.

Highlights

There have been studies on the association between nutritional status and functional limitations, there were few studies on Asian centenarians in community
Centenarians who were unable to participate in all surveys were excluded, including 268 older who died before the interview, 124 older who unable to participate in the physical examination, and 79 older who declined to participate. 1,002 centenarians (180 men and 822 women) were included in our survey
In this study of these extreme survivors, we found that malnutrition was significantly associated with the limitations of basic ADL (BADL) and instrumental ADL (IADL) among centenarians

Summary

Introduction

There have been studies on the association between nutritional status and functional limitations, there were few studies on Asian centenarians in community. This study aims to identify associations between nutritional status and functional limitations among centenarians in China. Because in the aging process, the human body inevitably experiences various functional declines; the problem of functional limitations [1] and deterioration of nutritional status [2] are more prominent. In terms of function, it has been proved that malnutrition can lead to functional limitations in the older [9,10,11]. This is because nutritional status may trigger changes in the structure and function of muscles. There are functional limitations and physical disability in older caused by muscle loss and other reasons [12]
