Blood adiponectin concentration at birth in small for gestational age neonates: A meta-analysis
1Department of Medicine and Public Health, Nagoya Medical Science Research Institute, Nagoya, Japan.
Insights
Blood adiponectin concentration is lower in small for gestational age (SGA) neonates compared to healthy controls. This finding highlights potential early indicators for neonatal health and future metabolic risks in SGA infants.
Area of Science:
- Neonatal Research
- Endocrinology
- Metabolic Health
Background:
- Small for gestational age (SGA) neonates face higher risks of mortality and morbidity.
- Adiponectin, a hormone from adipose tissue, plays a role in infant health and may predict adult metabolic complications.
- Understanding adiponectin levels at birth in SGA infants is crucial for early intervention.
Purpose of the Study:
- To investigate differences in blood adiponectin concentration at birth between SGA neonates and healthy controls.
- To synthesize existing evidence on adiponectin levels in SGA neonates.
Main Methods:
- A systematic literature search identified relevant English-language studies.
- Study quality was assessed using the Newcastle-Ottawa Scale (NOS).
- A meta-analysis was conducted to compare adiponectin levels between SGA neonates and controls.
Main Results:
- Five high-quality studies involving 253 neonates were analyzed.
- Blood adiponectin concentration was significantly lower in SGA neonates compared to healthy controls (P=0.016).
- A moderate effect size (SMD=0.4-0.7) indicated a consistent difference.
Conclusions:
- Neonates who are small for gestational age exhibit lower blood adiponectin concentrations at birth.
- This finding suggests adiponectin may serve as a biomarker for SGA-related health risks.
- Further research can explore the long-term implications of these lower adiponectin levels.
Aims:
Small for gestational age (SGA) is associated with increased rates of neonatal mortality and morbidity. Adiponectin secreted from adipose tissue is implicated in the etiology of death and illness during infancy. SGA is also a likely risk factor for the development of metabolic and clinical complications in adulthood. The present study was performed to determine whether SGA neonates and healthy controls show differences in blood adiponectin concentration at birth.
Methods:
Databases were searched to identify English-language studies providing the numbers of SGA neonates, the numbers of healthy controls, and the means and standard deviations (SDs) of blood adiponectin concentrations at birth in both groups. Study quality was assessed using the Newcastle-Ottawa Scale (NOS). A meta-analysis was performed to summarize the standardized mean differences (SMDs) in blood adiponectin concentration between SGA neonates and healthy controls.
Results:
The results summarized from five good quality (i.e., NOS score ≥ 5) studies involving 253 neonates showed that blood adiponectin concentration was significantly lower in SGA neonates than in healthy controls (P = 0.016), and the effect was moderate (i.e., SMD = 0.4-0.7).
Conclusions:
Synthetic evidence indicated that blood adiponectin concentration at birth is lower in SGA neonates than in healthy controls.
