ABSTRACT
Objective:To evaluate the diet quality of patients with Type 2 diabetes mellitus (T2DM) in the community with the Chinese Dietary Balance Index (DBI-16) and to provide a scientific basis for nutrition education.Methods:A random cluster sampling method was adopted to conduct a questionnaire survey of 332 T2DM patients in a community of Bengbu City to obtain demographic sociology and dietary intake information. DBI-16 was used to score and evaluate dietary structure and diet quality.Results:There are low-level under-intake (low bound score =14.0) and excessive intake (high bound score =14.0) in the diet of this population. The degree of excessive intake of men (high bound score =15.0) was higher than that of women (high bound score=13.0) ( Z=-3.12, P<0.01), and the degree of insufficient diet (low bound score =13.0) was lower than that of women (low bound score=15.5)( Z=-2.05, P<0.05). Those with monthly income<1 000 (low bound score =15.5) patients ( χ2 =6.34, P<0.05) and disease course>10 years (low bound score =16.0) had the highest degree of insufficient dietary intake ( χ2 =9.40, P<0.01). Those who did not participate in community health education lectures had significantly higher dietary intake (low bound score =15.0) and imbalance (diet quality distance= 29.0) than those who participated in community health education (low bound score=13.0)(diet quality distance=27.0)( Z=-2.46, P<0.01). According to the score distribution of the DBI-16 index, 73.6% of patients had a severe over-intake of cereals, and only 27.4% and 27.7% had intake of vegetables, fruits, and milk beans that reached the recommended intake. The dietary pattern mainly reflects the existence of a certain degree of excessive dietary intake pattern D. Conclusion:The dietary quality of T2DM patients in Bengbu′s community is in a state of low imbalance. Insufficient and excessive dietary intake coexist and urgently need to be improved.
