RESUMO
Objective@#To understand the dietary behavior of Tibetan primary school students in Lhasa from 2014 to 2019, and to provide support for dietary behavior improvement.@*Methods@#In 2014 and 2019, 1 128 and 1 214 Tibetan primary school students in Lhasa were investigated for dietary behavior, and the results were compared.@*Results@#The proportion of Tibetan primary school students in Lhasa who eat breakfast at home every day in 2019 (10.30%) was significantly higher than in 2014(2.39%), and the difference was statistically significant(χ2=60.17, P<0.01). The proportion of students who took the recommended amount of meat, eggs, and dairy products in 2019 was higher than in 2014, and the difference was statistically significant(χ2=242.05, 4.23, 14.16, P<0.05). In 2014 and 2019, the difference in the proportion of intake of vegetables and fruits was statistically significant(χ2=132.45, 115.64, P<0.01). In terms of the different types of beverages that were consumed the most in 2019, the differences were statistically significant(P<0.01); the intake frequencies were also significantly different(P<0.01).@*Conclusion@#The dietary behavior of Tibetan primary school students in Lhasa has generally improved, but the problems of overweight and obesity caused by excessive energy intake and excessive intake of sugary beverages deserves more attention.
