Adherence to the nutritional recommendations according to diabetes status in Korean adults: a cross-sectional study

Nutritional therapy plays a crucial role in diabetes management. Assessing adherence to nutritional recommendations is critical for evaluating whether the current status of nutrition education is appropriate. This study aimed to evaluate adherence to nutritional recommendations according to diabetes status using data from the Korean National Health and Nutrition Examination Survey from 2016 to 2019.

A total of 2,793 participants (55.4% male) were evaluated regarding their adherence to nutritional recommendations. The "aware" group comprised people who had been clinically diagnosed by a physician. The "treated" group comprised people receiving anti-diabetic medications. The "control" group comprised people who achieved an HbA1c level < 6.5%. The "educated" group comprised people who had received nutrition education or counseling at various locations.

Among the 1,918 individuals in the "aware" group, only 243 (8.7%) had received nutrition education. Adherence to nutritional recommendations was generally low, with people with diabetes showing slightly higher adherence to total energy intake (59.6% vs. 55.3%) and total sugar intake (88.0% vs. 84.5%) than people without diabetes. However, adherence to total carbohydrate intake was poor in both the treated and educated groups (34.3% and 26.0%, respectively) compared to the untreated and non-educated groups (44.4% and 36.0%, respectively).

These findings indicate inadequate nutritional management for people with diabetes in Korea. Nutrition education should be effectively strengthened to achieve nutritional goals.
