Insights
Childhood obesity is linked to increased inflammation and thrombotic risk. Overweight children show higher plasminogen activator inhibitor-1 (PAI-1) and lower vitamin D3 (VD) levels, indicating a significant health concern.
Area of Science:
- Pediatrics
- Endocrinology
- Public Health
Background:
- Childhood obesity is a global epidemic and a major public health threat.
- Obesity in children increases the risk of adult obesity and associated metabolic/hemostatic disorders.
- Elevated plasminogen activator inhibitor-1 (PAI-1) and deficient 25OH-vitamin D3 (VD) are linked to thrombotic events.
Purpose of the Study:
- To investigate the relationship between overweight/obesity and PAI-1/VD levels in children.
- To assess inflammation indices in relation to weight status and VD levels in pediatric patients.
- To evaluate the thrombotic risk in overweight and obese children.
Main Methods:
- PAI-1 and VD levels were measured in 259 overweight/obese children (ages 2-18) and 80 normal-weight controls.
- Participants were enrolled in a Nutritional Education Program at Bambino Gesù Children's Hospital.
- Inflammation indices, including HOMA-IR, were assessed.
Main Results:
- Overweight and obese children exhibited increased HOMA-IR and inflammation indices compared to normal-weight children.
- Lower levels of 25OH-vitamin D3 (VD) were observed in overweight/obese children.
- Elevated PAI-1 levels were found in the pediatric overweight/obese cohort.
Conclusions:
- Overweight and obesity in children are associated with heightened inflammation.
- The study confirms elevated PAI-1 and low VD levels in overweight/obese pediatric patients.
- These findings indicate a significant thrombotic risk in this population.
Background:
Childhood overweight and obesity have been described by the World Health Organization as noncommunicable diseases and among the greatest public health threats since they have reached epidemic proportions. A child with obesity risks becoming an adult with obesity and developing metabolic and hemostatic disorders which are the basis for the development of coronary heart diseases. Recently, a number of clinical reports have demonstrated that both an increase in plasminogen activator inhibitor-1 (PAI-1) and a deficiency in 25OH-vitamin D3 (VD) are associated with an increase in thrombotic episodes.
Methods:
PAI-1 and VD levels were measured in 259 clinically overweight and obese children aged between 2 and 18 years enrolled in the Nutritional Education Program of the Bambino Gesù Children's Hospital and Research Institute of Rome (Italy) and 80 normal-weight subjects.
Results:
We observed increased HOMA-IR, PAI-1, and other inflammation indices associated with decreased VD levels when compared to normal-weight children.
Conclusions:
Our results demonstrated that overweight and obesity are correlated with higher levels of the inflammation index. Moreover, our patients show high PAI-1 and low VD levels, confirming the high thrombotic risk in our pediatric population.
