Abstract

BACKGROUND

Dietary diversity is influenced by nutritional literacy. This study sought to investigate associations between nutritional literacy and dietary diversity among elderly Chinese individuals with chronic diseases and clarify how nutritional literacy affects dietary diversity.

METHODS

Three communities in Hangzhou, Zhejiang Province were chosen at random to assess nutritional literacy and diet status, which included 301 individuals over the age of 60 with chronic diseases.

RESULTS

The elderly had a middle and lower level of nutritional literacy (n = 301,20.16±5.45). Dietary diversity scores (DDSs) and nutrition literacy showed a positive correlation (r = 0.366, P < 0.001). Higher DDSs were seen in those with greater education levels (OR = 2.15,95 %CI = 1.57∼2.94) and those with better awareness of diet and health (OR = 1.29,95 % CI = 1.02∼1.55).

CONCLUSIONS

The elderly face significant challenges in maintaining a reasonable nutritional intake over time and their nutritional literacy warrants attention.

摘要

背景

饮食多样性受营养知识水平影响。本研究旨在调查中国老年慢性病患者营养知识水平与饮食多样性之间的关联，并阐明营养知识水平如何影响饮食多样性。

方法

随机选取浙江省杭州市的三个社区，对301名60岁以上的慢性病患者进行营养知识水平和饮食状况评估。

结果

老年人的营养知识水平处于中低水平（n = 301，20.16±5.45）。饮食多样性得分（DDSs）与营养知识水平呈正相关（r = 0.366，P < 0.001）。受教育程度较高者（OR = 2.15，95%CI = 1.57∼2.94）以及饮食与健康意识较好者（OR = 1.29，95%CI = 1.02∼1.55）的DDSs较高。
