Insights
Elevated serum free fatty acid (FFA) levels are significantly higher in children with primary hypertension. Increased FFA is an independent risk factor, highlighting its role in pediatric hypertension development.
Area of Science:
- Pediatric Endocrinology
- Cardiovascular Research
- Metabolic Syndrome
Context:
- Primary hypertension in children is a growing concern.
- Serum free fatty acid (FFA) levels are increasingly recognized as potential contributors to metabolic and cardiovascular diseases.
- Understanding the role of FFA in pediatric hypertension is crucial for early intervention.
Purpose:
- To investigate the association between serum FFA levels and primary hypertension in children.
- To determine if elevated FFA is an independent risk factor for pediatric primary hypertension.
- To explore the value of FFA in the pathogenesis, prevention, and treatment of childhood hypertension.
Summary:
- This retrospective study compared 34 children with primary hypertension to 32 controls.
- Hypertensive children exhibited higher BMI, blood pressure, and elevated serum FFA, triglycerides, LDL-C, and non-HDL-C, with lower HDL-C.
- Multivariate logistic regression identified elevated serum FFA as an independent risk factor for primary hypertension in children (OR=17.560).
Impact:
- Findings suggest that elevated serum FFA is a significant risk factor for primary hypertension in children.
- This research highlights the potential of monitoring and managing FFA levels for hypertension prevention and treatment in pediatric populations.
- The study underscores the importance of metabolic factors in the development of childhood hypertension.
Objectives:
To examine the serum level of free fatty acid (FFA) in children with primary hypertension and its value in the pathogenesis, prevention, and treatment of primary hypertension in children.
Methods:
In this retrospective study, 34 children with primary hypertension who were treated for the first time in Children's Hospital Affiliated to Capital Institute of Pediatrics from January to June, 2021, were enrolled as the hypertension group, and 32 children with normal blood pressure who underwent physical examination during the same period were enrolled as the control group. The two groups were compared in terms of the levels of fasting serum FFA, fasting serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and non-high-density lipoprotein cholesterol (non-HDL-C). The multivariate logistic regression model was used to analyze the influence of FFA on the development of primary hypertension.
Results:
Compared with the control group, the hypertension group had significantly higher body mass index (BMI), systolic blood pressure, and diastolic blood pressure (P<0.05), as well as significantly higher serum levels of FFA, TG, LDL-C, and non-HDL-C and a significantly lower serum level of HDL-C (P<0.05). Compared with the control group, the hypertension group had significantly higher rates of elevated serum FFA (>0.45 mmol/L for girls and >0.60 mmol/L for boys) (P<0.05) and abnormal blood lipid levels (abnormality in at least one index among serum TG, TC, LDL-C, HDL-C, and non-HDL-C) (P<0.05). A multivariate logistic regression equation was established based on age, sex, BMI, elevated serum FFA, and abnormal blood lipid levels, and the results showed that elevated serum FFA was an independent risk factor for primary hypertension in children (OR=17.560, 95%CI: 1.964-157.003, P<0.05).
Conclusions:
There is a significant increase in serum FFA level in children with primary hypertension, and the increase in serum FFA can increase the risk of primary hypertension in children.
