Objective To explore the clustering of lifestyle among middle school students in Zhengzhou and its correlation with high blood pressure, in order to provide a scientific basis for the development of effective strategies for preventing and controlling high blood pressure in adolescents. Methods A multi-stage cluster random sampling method was used to select 8 middle schools in Zhengzhou in 2021, with a total of 2 791 students included. A self-made questionnaire was used to investigate their general information and dietary and exercise behaviors, as well as measuring their height, weight, and blood pressure. A latent class clustering analysis was conducted, as well as a binary logistic regression analysis for correlation. Results In total 23.5% of the middle school students were reported to have high blood pressure, with a higher prevalence among junior high school students (26.0%) than high school students (20.2%) (χ2=12.760, P<0.001). A latent class clustering analysis of dietary and exercise behaviors identified two categories: sub-healthy and healthy lifestyles. Logistic regression analysis found that after adjusting for gender, ethnicity, age, grade, and BMI, the risk of high blood pressure in sub-healthy students was 1.357 times that of healthy students (OR=1.357, 95%CI: 1.083-1.701). Conclusion Sub-healthy lifestyles increase the risk of high blood pressure in adolescents, providing new information for exploring the risk factors of cardiovascular and metabolic abnormalities in adolescents as well as the prevention and control of high blood pressure in adolescents.
