Childhood Obesity and Systemic Arterial Hypertension in Children and Adolescents: A Cross-Sectional Study

Abstract

Background:

The increase in obesity cases and the lack of screening and diagnosis of childhood hypertension highlight the need to examine these comorbidities in children.

Objectives:

To investigate the relationships between systemic arterial hypertension (SAH) and childhood obesity (CO) in pediatrics and correlate the obesity level, abdominal circumference (AC), family history, and physical activity (PA) variables.

Methods:

This cross-sectional study assessed age, sex, height, weight, body mass index (BMI), AC, family history, PA, CO, and blood pressure (BP) percentiles. The Chi-square test, Fisher’s Exact test, and Spearman’s correlation were used for data analysis, with a statistical significance level of 5%.

Results:

After applying the inclusion and exclusion criteria, 30 patients aged between 3 and 18 years (incomplete) were evaluated at three different moments. The results showed that 83.3% (n = 25) of the patients were obese and 16.70% (n = 5) had severe obesity. Among them, 20% (n = 6) were diagnosed with SAH. Data showed an independence between CO and SAH (p = 0.702) and between SAH and PA time (p = 0.748). No correlations were observed between SAH and AC (p = 0.313). The history of SAH in first-degree relatives was significantly associated with the diagnosis of SAH (p = 0.004).

Conclusion:

This study showed no correlation between CO and SAH in the evaluated sample, supporting the need for further research in the area.
