Correlation of Body Mass Index and Puberty with Blood Pressure in Healthy Adolescents
Abstract
Background: Limited research in the Indian populati on hinders our understanding of how blood pressure is infl uenced by factors such as body mass index and puberty.
Objective: To study the relati on of body mass index and pubertal stage with blood pressure in healthy adolescents.
Methods: The study design was an observati onal descripti ve study. Parti cipants included 518 adolescents aged 10 to 18 years at Kalawati Saran Children’s Hospital, with representati on from each pubertal stage. The primary outcome aimed to examine the correlati on between body mass index and blood pressure, parti cularly within diff erent pubertal stages. The secondary outcome focused on the correlati on between
height and blood pressure, as well as the development of a blood pressure nomogram based on body mass index.
Results: Height showed a signifi cant (p < 0.05) positi ve correlati on with systolic (r = 0.604 in males, r = 0.509 in females) and diastolic blood pressure (r = 0.566 in males, 0.488 in females). The body mass index positi vely correlated with systolic (r = 0.356 for males, r = 0.366 for females) and diastolic blood pressure (r = 0.336 for males, r = 0.435 for females). Percenti les for systolic and diastolic blood pressure were calculated across diff erent body mass index and height groups for both males and females. Correlati on coeffi cients between puberty and systolic blood pressure were 0.5 (p < 0.01) and 0.4 (p < 0.01) in males and females, and for diastolic blood pressure were 0.4 (p < 0.01) for both genders.
Conclusion: A positi ve correlati on exists between systolic and diastolic blood pressure with height, body mass index and all pubertal stages in both males and females in all age groups.
