To explore the level and influencing factors of dietary recommendation knowledge among residents aged 18-64 years in Hunan Province in 2021, and to provide a reference for targeted dietary nutrition education.
In 2021, a total of 4351 adult residents from 13 districts (counties) survey sites of Hunan Province were surveyed using the Nutrition and Health Knowledge Questionnaire. The total score of the questionnaire was 100. The knowledge dimension of dietary recommendation included 19 knowledge points, with a total score of 30, the total score of this dimension ≥ 22.5 was considered to be aware of dietary recommendation related knowledge. Binary logistic regression was used to analyze the influencing factors of adult residents’ knowledge level of dietary recommendation.
A total of 4 010 adults were included in the survey, with an average age of (38.6±12.0) years. The average score of dietary recommendation knowledge dimension was (17.7±4.4) points, and the awareness rate of knowledge about dietary recommendations was 13.6%. The results showed that there were significant differences in the scores and awareness rates of dietary recommendation related knowledge among residents with different genders, age groups, education levels, work units and specific situation of chronic diseases (P<0.05). Logistic regression analysis showed that compared with the corresponding reference group, the awareness rate of dietary recommendation related knowledge was relatively higher in female residents (OR=1.267, 95%CI=1.051 - 1.526) and residents with education level of junior high school and above [junior high school (OR=1.528, 95%CI=1.042-2.242), seniorhigh school (OR=2.123, 95%CI=1.421 - 3.172), college/professional college (OR=3.653, 95%CI=2.386-5.593),bachelor’s degree and above (OR=3.385, 95%CI=2.120 - 5.405)]. Compared with those working in medical and health institutions, those working in education-related institutions had a lower awareness rate of dietary recommendation knowledge (OR=0.547, 95%CI: 0.322-0.930). Compared with those without chronic diseases, the awareness rate of dietary recommendation was lower in adults who did not know their specific situation of chronicdiseases (OR=0.613, 95%CI=0.487-0.772).
There is significant room for improvement in the knowledge level of diet recommendation among adult residents in Hunan Province. In the future, more attention should be paid to the dietary nutrition education of adult males, middle-aged and elderly people, patients with chronic diseases, and residents who do not work in medical and health institutions.
