Abstract
Introduction: high blood pressure (HBP), once considered rare in adolescents is now a growing health problem. Usually asymptomatic in adolescents, if uncontrolled, can track into adulthood leading to various end-organ complications. In 2017, the American Academy of Pediatrics (AAP) published a new Clinical Practice Guideline (CPG) for screening and management of high blood pressure in children and adolescents to update the 2004 Fourth report. The objective of this study was to determine the prevalence of high blood pressure among adolescents in Mushin Local Government Area (LGA) using the 2017 AAP guidelines.
Methods: a descriptive cross-sectional study, conducted from August 2020 to December 2020. A two-stage sampling technique was used to select 1490 students aged 10 to 19 years, from 14 secondary schools. Socio-demographic information and relevant clinical data were obtained using a structured questionnaire. The anthropometry and blood pressure measurements were taken according to standard protocol (elevated blood pressure is systolic and/or diastolic blood pressure ≥ 90th percentile but ≤ 95th percentile for age, gender and height). Socio-demographic and anthropometric characteristics were described with descriptive statistics. Categorical variables were summarized using frequency and percentages, while numerical variables were summarized using mean and standard deviation. The predictors of hypertension were determined using logistic regression analysis.
Results: study participants were 1490, 49.9% (744) were male and 50.1% (746) females (male: female ratio was 1:1). Subjects mean age was 14.39 ± 2.79 years. There were 8.9% overweight and 1.7% obese participants. Prevalence of high blood pressure, elevated blood pressure and hypertension were 26.7% (n = 398), 13.8% (n = 205), and 12.9% (n = 193). Middle and late adolescence, when compared to early adolescence, significantly predicted the likelihood of high blood pressure; aOR 1.78, 95%CI: 1.20 - 2.63, p=0.004 and 3.90 (2.69 - 5.67, p=0.001 respectively). Similarly, male sex had increased odds for raised blood pressure when compared to female sex aOR 1.49,95% CI: 1.1 - 2.0, p= 0.009.
Conclusion: the prevalence of high blood pressure, elevated blood pressure and hypertension amongst adolescents was high. Early detection and treatment will forestall development of complications.
