Insights
Fetal growth restriction (FGR) impacts childhood cardiovascular health. Breastfeeding and healthy fats improve outcomes, while obesity worsens them, suggesting early intervention potential.
Area of Science:
- Pediatric Cardiology
- Developmental Pediatrics
- Nutritional Science
Background:
- Fetal growth restriction (FGR) is linked to long-term cardiovascular risks.
- Understanding postnatal influences on FGR-induced cardiovascular remodeling is crucial.
Purpose of the Study:
- To investigate the impact of breastfeeding and postnatal nutrition on cardiovascular remodeling in children with FGR.
- To assess cardiovascular endpoints in children with FGR compared to those with adequate fetal growth (AGA).
Main Methods:
- A cohort study included 81 children with FGR and 121 with AGA, assessed at 4-5 years of age.
- Cardiovascular endpoints measured: left ventricular sphericity index (LVSI), carotid intima-media thickness (cIMT), and blood pressure (BP).
- Linear and robust regressions analyzed the combined effects of FGR and postnatal factors (breastfeeding, diet, BMI).
Main Results:
- FGR was a significant predictor of adverse cardiovascular remodeling (lower LVSI, higher cIMT and BP).
- Extended breastfeeding (>6 months) and healthy-fat intake showed protective effects on LVSI and cIMT, respectively.
- Overweight/obesity exacerbated cIMT in FGR children; BMI and weight catch-up increased BP.
Conclusions:
- Postnatal nutrition can mitigate cardiovascular remodeling associated with FGR.
- Breastfeeding and healthy fats are beneficial, whereas increased BMI is detrimental to cardiovascular health in this population.
- These findings highlight opportunities for early, targeted postnatal interventions to improve cardiovascular outcomes.
Background:
Our aim was to determine the influence of breastfeeding and postnatal nutrition on cardiovascular remodeling induced by fetal growth restriction (FGR).
Methods:
A cohort study including 81 children with birthweight <10th centile (FGR) and 121 with adequate fetal growth for gestational age (AGA) was conducted. Cardiovascular endpoints were left ventricular sphericity index (LVSI), carotid intima-media thickness (cIMT), and blood pressure (BP) at 4-5 y of age. The combined effect of FGR and postnatal variables-including breastfeeding, fat dietary intake, and BMI-on cardiovascular endpoints was assessed by linear and robust regressions.
Results:
FGR was the strongest predictor of cardiovascular remodeling in childhood, leading to lower LVSI and increased cIMT and BP as compared with AGA. Breastfeeding >6 mo (coefficient: 0.0982) and healthy-fat dietary intake (coefficient: -0.0128) showed an independent beneficial effect on LVSI and cIMT, respectively. Overweight/obesity induced an additional increment of 1 SD on cIMT in FGR children (interaction coefficient: 0.0307) when compared with its effect in AGA. BMI increased systolic BP (coefficient: 0.7830) while weight catch-up increased diastolic BP (coefficient: 4.8929).
Conclusions:
Postnatal nutrition ameliorates cardiovascular remodeling induced by FGR. Breastfeeding and healthy-fat dietary intake improved while increased BMI worsened cardiovascular endpoints, which opens opportunities for targeted postnatal interventions from early life.

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
