Abstract:

Objective: To investigate nutritional knowledge, attitudes and dietary behaviors of teachers and students in a medical college in Beijing and their influencine factors, and to provide evidence for nutrition education and promotion. Methods: The subjects of this study were teachers, as well as first-year and second-year graduate students, and first-year to third-year undergraduate students. The teachers and students were respectively sampled by stratified cluster sampling with equal proportion. t-test or ANOVA was used to compare the means between the groups, and multiple linear regression was used to analyze the influencing factors of knowledge, attitude and practice (KAP) score. Results: The average score of nutrition knowledge was 5.7±1.5. The knowledge rate of nutrition was 57.3%. The average score of nutritional attitudes was 8.3±3.0. The mean nutritional behavior score was 5.1±2.0. The average nutritional KAP score was 19.1±4.6, with the teachers 19.9±5.2 higher than the students 18.9±4.5; the female 19.5±4.5 higher than the male 18.4±4.5; All the differences were statistically significant (P<0.05). The scores of nutritional attitudes, nutritional behavior and total KAP scores of doctoral students were significantly higher than those of the undergraduate and postgraduate students (P<0.01). Conclusion: The nutrition attitudes of teachers and students is relatively correct, the nutrition knowledge needs to be further strengthened, and there are some unreasonable aspects in the nutrition behaviors. Gender, identity and degree are the main influencing factors of the nutrition score of knowledge, attitudes and behaviors. It is necessary to carry out nutritional education in schools to improve the nutrition knowledge of teachers and students, correct bad eating habits, and promote the construction of healthy China action.

Key words: Nutritional status, Nutritional knowledge, attitudes, behaviors, Diet habits, College teachers and students
