To analyse the association between high blood pressure and dietary behaviors among children and adolescents aged 9 to 17 years in Inner Mongolia, and to develop targeted preventive measures for high blood pressure among children and adolescents in Inner Mongolia.
The data were obtained from the National Monitoring and Intervention Work Program for Common Diseases and Health Influencing Factors in Students, and a total of 129 821 primary and secondary school students were included in the stratified random cluster sampling method in September each year. The χ2 test was used for the analysis of single factors, and binary logistic regression was used for multifactorial analyses, and risk prediction of high blood pressure was performed by column-line plots.
In Inner Mongolia, the overall high blood pressure of children and adolescents aged 9-17 years was 16.23%, with simple systolic blood pressure increase as the main cause. By gender, the overall high blood pressure rates of boys and girls were 15.42% and 17.05%, respectively, and the difference was statistically significant (χ2=63.38, P<0.001); the overall high blood pressure rates of primary schools, junior high school, and high school were 14.95%, 16.89%, and 17.77%, respectively, according to the school segments. The difference was statistically significant (χ2=124.95, P<0.001). Logistic regression model analysis showed that the risk of high blood pressure was higher in female students than in male students (OR=1.13, 95% CI:1.10-1.17), and the risk of high blood pressure was higher in junior high school and high school students than in primary school students [OR=1.14(95% CI:1.10-1.18), 1.18(95% CI:1.13-1.23), respectively], the risk of high blood pressure was lower for students in flag counties than for students in urban areas (OR=0.89,95% CI:0.86-0.92), and the rate of high blood pressure was lower for Mongolian and other students than for Han Chinese students [OR=0.96(95% CI:0.92-0.99), and 0.93(95% CI:0.87-0.99)], the risk of high BP was lower for those who ate fried food ≤1 time per week than for those who ate it ≥2 times per week (OR=0.86,95% CI:0.77-0.97), the risk of high BP was lower for those who ate chocolate ≤1 time per week than for those who ate it ≥2 times per week (OR=0.94,95% CI:0.91-0.97), and the risk of high BP was lower for those who ate butter ≤1 time per week had a lower risk of high blood pressure than students who ate it ≥2 times per week (OR=0.95,95% CI:0.92-0.98), ate pastry ≤1 time per week had a lower risk of high blood pressure than students who ate it ≥2 times per week (OR=0.93,95% CI:0.90-0.96), and drank soya milk ≤1 time per week had a higher risk of high blood pressure than students who drank it ≥2 times per week (OR=1.13,95% CI:1.03-1.24), and students who ate breakfast every day had a higher risk of high blood pressure than those who ate it sometimes or never [OR=1.15(95% CI:1.11-1.19),1.23(95% CI:1.15-1.31), respectively].
Dietary behaviour is closely associated with high blood pressure in children and adolescents, and this aspect should be actively addressed in future preventive measures.
