Insights
Infants born preterm or small for gestational age face a higher risk of early childhood caries. While metabolic syndrome signs didn't differ, higher fasting glucose correlated with caries in preschoolers.
Area of Science:
- Pediatric Dentistry
- Neonatology
- Metabolic Health
Background:
- Early childhood caries (ECC) is a significant public health concern.
- Perinatal factors and metabolic health are potential contributors to ECC risk.
Purpose of the Study:
- To investigate the association between perinatal and metabolic risk factors and ECC in preschool children.
- To identify specific risk factors that predict ECC development.
Main Methods:
- A cohort of 208 children was followed from birth to 6.5 years.
- Perinatal data were collected via medical records and questionnaires.
- Caries occurrence was assessed at 5 years; metabolic syndrome indicators were measured at 6.5 years.
Main Results:
- Infants born moderately to late preterm (RR 4.2) and small for gestational age (RR 2.3) had increased odds of ECC.
- No significant differences in metabolic syndrome risk factors were observed between children with and without caries.
- A positive correlation was found between fasting glucose levels and the number of decayed or filled teeth (r=0.18).
Conclusions:
- Preterm birth and being small for gestational age are significant risk factors for developing early childhood caries.
- While overall metabolic syndrome indicators did not differ, elevated fasting glucose levels were associated with ECC in preschool children.
Aim:
To study the relationship between early childhood caries and perinatal and metabolic risk factors in a cohort of preschool children.
Methods:
The study population consisted of 208 children followed from birth to 6.5 years. We extracted the perinatal factors from medical records and questionnaires and assessed the occurrence of caries at the age of 5 years. Indicators of the metabolic syndrome (waist circumference, blood pressure, fasting insulin, glucose and dyslipidaemia) were recorded at 6.5 years of age.
Results:
Infants born moderately to late preterm and infants born small for gestational age were more likely to have early childhood caries at 5 years of age (relative risk 4.2 and 2.3, respectively; P < .05). The presence of metabolic risk factors according to the IDEFICS monitoring levels did not differ between children with or without caries but a statistically significant correlation was found between the fasting glucose values and the number of decayed or filled teeth (r = 0.18; P < .05).
Conclusion:
Being born preterm or small for gestational age increased the risk of early childhood caries. Preschool children with caries had higher fasting glucose levels but no other signs of the metabolic syndrome.
