Insights
Breastfeeding for 3-6 months lowers early childhood caries (ECC) risk. Conversely, nighttime bottle-feeding and exclusive bottle-feeding significantly increase ECC incidence in preschool children.
Area of Science:
- Pediatric Dentistry
- Public Health
- Epidemiology
Background:
- Early childhood caries (ECC) is a prevalent chronic disease in children.
- ECC is linked to infant feeding practices.
Purpose of the Study:
- To determine the association between breastfeeding and bottle-feeding practices and early childhood caries in preschool-aged children.
Main Methods:
- Interviewer-administered questionnaires collected data on oral health, infant feeding, and family characteristics.
- Intra-oral examinations assessed dental caries using WHO criteria.
- Chi-square and logistic regression analyses were performed.
Main Results:
- ECC incidence was significantly higher with nighttime bottle-feeding (OR=4.5).
- Breastfeeding for 3-6 months showed a significantly lower ECC risk (OR=0.1) compared to breastfeeding >12 months.
Conclusions:
- Breastfeeding for 3-6 months is associated with reduced ECC incidence.
- Exclusive bottle-feeding and nighttime bottle-feeding are linked to increased ECC rates.
Background:
Early childhood caries constitute one of the most prevalent chronic diseases among children which have been found to be related to infant feeding practices.
Objective:
to determine the association of early childhood caries with breastfeeding and bottle-feeding practices among children of preschool age.
Patients & Methods:
Information about oral health, infant feeding and other child and family characteristics were obtained through structured interviewer administered questionnaire from mothers of preschool children. Intra-oral examination of the children was done and dental caries status was recorded according to the World Health Organization (WHO) criteria. The data were analysed using Statistical Package for Social Sciences (SPSS) version 20.0. Statistical analyses of association of early childhood caries with various categorical variables were performed using chi-square. A logistic regression analysis was also performed with factors that were significant. P-value ≤ 0.05 was considered statistically significant.
Results:
Of the 302 children in this study, 44% were solely breastfed, 2% were solely bottle-fed while 54% were both breastfed and bottle-fed. Statistical analysis showed that ECC significantly increased with night time bottle feeding (OR=4.5, p=0.001, CI=1.8-11.1), whereas it was significantly lower in children who were breastfed for 3 to 6 months (OR= 0.1, p<0.001, CI=0.03-0.18) as compared to those who were breastfed greater than 12 months duration.
Conclusion:
. This study has shown that breastfeeding for the first 3 - 6 months of life is associated with low incidence of dental caries while babies solely bottle-fed and night time bottle feeding are associated with high incidence of childhood dental caries.
