Relationship between processed food consumption and blood pressure of students in a university in Yunnan Province
Objective To explore the relationship between processed food consumption and blood pressure level of students in a university in Yunnan Province,so as to provide the reference for preventing hypertension in university students.Methods In Octo-ber 2021,a cluster sampling method was used to select 4 781 freshmen from a university in Kunming,Yunnan Province.The fre-quency of processed food consumption of university students was assessed by using the dietary frequency questionnaire,and height,weight and blood pressure were measured.Mann-Whitney test and Kruskal-Wallis test were used to compare the differences in blood pressure level of university students with different demographic variables,and the association between processed food con-sumption and blood pressure level was analyzed with a generalized linear model.Results Among the students of a university in Yunnan Province,the detection rates of systolic prehypertension and hypertension were 33.86％and 1.23％,and the detection rates of diastolic prehypertension were 32.13％and hypertension 7.22％.The results of generalized linear model analysis showed that after controlling for demographic variables and other variables that might affect the blood pressure level of university students,the con-sumption of processed food(bread and cake:β=0.15,95％CI=0.01-0.29)and ultra-processed food(coffee beverage:β=-0.29,95％CI=-0.54--0.03)were associated with systolic blood pressure level(P＜0.05).The consumption of processed food(salted duck egg:β=0.21,95％CI=0.01-0.41)was correlated with the diastolic blood pressure of college students(P＜0.05).Conclu-sions Processed food consumption in university students may increase the risk of high blood pressure.The education of healthy eat-ing among college students should be strengthened to reduce the consumption of processed foods.
