OBJECTIVE: This study aims to examine the prevalence of elevated blood pressure (BP) among adolescents aged 13-17 years in Shiyan city, Hubei province, China. Additionally, it analyses the distribution characteristics and potential factors influencing elevated BP, providing a scientific foundation for the prevention and management of hypertension in adolescents.
DESIGN: Cross-sectional study.
SETTING: A total of 11 schools in central China.
PARTICIPANTS: From October 2023 to January 2024, a cross-sectional study involving 8534 students aged 13-17 years from 11 schools in central China was conducted. Convenience sampling was used to select participants, and data were collected through questionnaires and medical physical examinations.
PRIMARY OUTCOME MEASURES: This study used physiological measurement to assess BP levels, while questionnaire surveys and anthropometric measurements were employed to identify associated factors.
RESULTS: The overall detection rate of elevated BP was 22.7% (20.2% for boys and 25.6% for girls). Increased body mass index (BMI) (OR: 1.026, 95% CI: 1.003 to 1.048), neck circumference (OR: 1.099, 95% CI: 1.073 to 1.126) and chest circumference (OR: 1.015, 95% CI: 1.007 to 1.023) were associated with an increased risk of elevated BP. Conversely, longer screen time was linked to a lower risk of elevated BP (OR: 0.961, 95% CI: 0.942 to 0.98). Girls (OR: 1.592, 95% CI: 1.419 to 1.787) were at higher risk than boys. Additionally, not consuming meat or poultry (OR: 2.029, 95% CI: 1.171 to 3.514) was identified as a risk factor for elevated BP.
CONCLUSION: The distribution of elevated BP among adolescents exhibited population heterogeneity. Elevated BP was found to be associated with higher BMI, neck circumference and chest circumference, as well as the absence of meat consumption. Additionally, targeted attention to girls is essential for preventing elevated BP.
