Insights
Serum apelin levels are higher in obese children and linked to metabolic complications like insulin resistance and hypertension. Fasting blood glucose is a key predictor of apelin levels in this population.
Area of Science:
- Pediatric Endocrinology
- Metabolic Syndrome Research
- Adipokine Signaling
Background:
- Childhood obesity is a global health concern.
- Adipocytes release adipokines that regulate metabolism.
- Apelin is an adipokine implicated in metabolic processes.
Purpose of the Study:
- To investigate the association between serum apelin and childhood obesity.
- To explore the relationship between apelin and obesity-related complications such as hypertension and hyperglycemia.
Main Methods:
- Study included 50 obese and 31 non-obese children.
- Assessed anthropometric measurements, blood pressure, lipid profile, serum insulin, fasting blood glucose (FBG), HOMA-IR, and serum apelin.
- Compared parameters between obese and non-obese groups.
Main Results:
- Obese children exhibited elevated HbA1c, FBG, insulin, HOMA-IR, cholesterol, triglycerides, LDL, and DBP Z-scores.
- Serum apelin levels were significantly higher in obese children.
- Apelin positively correlated with BMI Z-Score, DBP Z-Score, cholesterol, TG, insulin, FBG, and HOMA-IR.
Conclusions:
- Apelin may play a role in the development of obesity-related health issues in children.
- Findings suggest apelin's involvement in insulin resistance and hypertension.
- Apelin may contribute to the risk of metabolic syndrome in pediatric obesity.
Background:
The rapidly increasing prevalence of childhood obesity became a major burden on health worldwide, giving an alarm to clinicians and researchers. Adipocytes act as an active endocrine organ by releasing plenty of bioactive mediators (adipokines) that play a major role in regulating metabolic processes. Apelin is a recently identified adipokine that is expressed in adipocytes.
Aim:
The current work aimed to uncover the relation between serum apelin and childhood obesity and its related complications as hypertension and hyperglycemia.
Method:
A group of 50 obese and 31 non-obese; sex- and age-matched children were enrolled in our study with a mean age of (9.5 ± 2.1) and (8.7 ± 1.3) respectively. Anthropometric measurements, blood pressure, were assessed in all studied participants, we also determined the lipid profile, serum insulin, fasting blood glucose (FBG) level, HOMA-IR and serum apelin.
Results:
Obese children had higher levels of HbA1c, FBG, serum insulin, HOMA-IR, total cholesterol, triglycerides, low-density lipoprotein (LDL) and diastolic blood pressure (DBP Z-score); compared to controls (all P < 0.05). Apelin was significantly higher in obese children versus controls and correlated positively with BMI Z-Score (P = 0.008), DBP Z-Score (P = 0.02), cholesterol, TG (both P = 0.02), serum insulin (P = 0.003), FBG and HOMA-IR (both P = 0.001). Linear regression analysis showed that FBG was the most effective factor in predicting the level of serum apelin (P = 0.04).
Conclusion:
This work supports the hypothesis that apelin may have a crucial role in the pathogenesis of health hazards related to obesity in children including insulin resistance, hypertension and a higher risk of occurrence of metabolic syndrome.
