[Correlation of dietary quality and blood glucose and lipid of the elderly in the community in Beijing from 2013 to 2015].

OBJECTIVE

To evaluate the diet quality of the Chinese elderly using adjusted Chinese Diet Balance Index( DBI-07) and to explore the association between dietary patterns and blood glucose and lipid with the aiming to provide scientific basis and theoretical support for nutrition education intervention.

Questionnaires were used to collect the information of demographic characters. Food intake information was collected by food frequency questionnaire( FFQ) method, and the dietary quality was evaluated by DBI-07 scoring and evaluating system.

There was significant difference in blood glucose and high density lipoprotein-cholesterol levels between the subjects with different dietary patterns( P < 0. 05).
