Oct 13, 2025 by wbrum.org 79 views

Introduction

The diagnosis of hypertension in children and adolescents is a complex and challenging task in the field of medicine. This is due to the lack of clear criteria and variations that occur in physiological parameters between individuals. One method that has emerged as a potential screening tool is the ratio of blood pressure to height (BP/H). This study aims to evaluate the effectiveness of this ratio in diagnosing hypertension in adolescents.

The Importance of Accurate Hypertension Diagnosis in Adolescents

Hypertension in children and adolescents is a significant public health concern. If left undiagnosed and untreated, it can lead to long-term complications such as cardiovascular disease, kidney disease, and stroke. Accurate diagnosis of hypertension in adolescents is crucial to prevent these complications and ensure optimal health outcomes. However, the diagnosis of hypertension in this age group is often challenging due to the lack of clear criteria and variations in physiological parameters.

The Ratio of Blood Pressure to Height (BP/H) as a Screening Tool

The ratio of blood pressure to height (BP/H) has emerged as a potential screening tool for hypertension in adolescents. This ratio is calculated by dividing the blood pressure by the height of the individual. The use of this ratio as a screening tool is based on the assumption that it can provide a simple and effective way to identify individuals who are at risk of hypertension.

Research Methodology

This study was conducted in Singkuang Village, North Sumatra, and involved 432 healthy teenagers aged 12 to 17 years. The study used the Fourth Report from the National High Blood Pressure Education Program Working Group on Children and Adolescents as a reference for the gold standard for hypertension diagnosis. The study also used the Receiver Operating Characteristic (ROC) curve analysis to identify the accuracy of the BP/H ratio.

Results and Findings

The results of this study showed that the accuracy of the BP/H ratio in both sexes reached more than 90% with a value of P <0.001. This indicates that the BP/H ratio can be relied upon as a screening method for hypertension in adolescents. The optimal intersection point for SBPHR and DBPHR in determining hypertension was found to be 0.787 and 0.507 in adolescent boys, while in adolescent girls, it was 0.836 and 0.541. The sensitivity of SBPHR and DBPHR in both sexes was also very high, with a value of more than 93%, and a specificity of 81%.

Positive and Negative Alleged Values

The positive alleged value obtained in this study shows the need to be careful in the interpretation of the results, especially for adolescent boys who have a positive alleged value of 38.7% and 45.2%, while for adolescent girls, the value is higher, namely 55.9% and 42.4%. However, a negative suspect value of more than 97% in both sexes shows that this ratio is very effective in diagnosing individuals who are not hypertension.

Conclusion

From the results of this study, it can be concluded that the ratio of blood pressure to height is a simple but effective method for screening hypertension in adolescents. With high sensitivity and specificity, this tool can be a useful alternative in clinical practice. However, more research is needed to determine the limits of this ratio based on race and other demographic factors. Through more in-depth research, we can increase accuracy in diagnosing hypertension in the population of children and adolescents, which in turn will help in preventing long-term complications caused by hypertension.

Recommendations

Based on the findings of this study, the following recommendations can be made:

The BP/H ratio can be used as a screening tool for hypertension in adolescents.
Further research is needed to determine the limits of this ratio based on race and other demographic factors.
More in-depth research is needed to increase accuracy in diagnosing hypertension in the population of children and adolescents.
The use of the BP/H ratio as a screening tool should be accompanied by regular monitoring and follow-up to ensure optimal health outcomes.

Limitations of the Study

This study has several limitations, including:

The study was conducted in a single location, and the results may not be generalizable to other populations.
The study used a relatively small sample size, which may limit the accuracy of the results.
The study did not control for other factors that may influence the results, such as socioeconomic status and access to healthcare.

Future Research Directions

Future research should focus on:

Determining the limits of the BP/H ratio based on race and other demographic factors.
Increasing accuracy in diagnosing hypertension in the population of children and adolescents.
Developing more effective screening tools for hypertension in adolescents.
Investigating the long-term effects of hypertension in adolescents on cardiovascular disease and other health outcomes.
