Prevalence of dental carries and its association with breastfeeding duration among young children in Addis Ababa, Ethiopia

Abstract

Abstract Background Breastfeeding is a crucial feeding practices that significantly contributes to the healthy development of children. However, the effect of breastfeeding duration on caries risk is unclear, as different studies have found different results. This study aims to assess the prevalence of dental caries and its association with breastfeeding duration among young children aged 12–36 months in selected health facilities of Addis Ababa, Ethiopia. Methods A cross-sectional study among 380 children aged 12–36 months from 11 health centers in Addis Ababa was conducted. Questionnaires and dental examinations were used to collect data. Dental caries was measured by the deft (decayed–extracted–filled teeth) index. Binary logistic regression was used to assess the association between dental caries and duration of breastfeeding, after adjusting for the confounders. Results The prevalence of dental caries was 53.4% (95% CI: 48.3, 58.5%), with 13.7% having high caries and 39.7% having low caries. Breastfeeding duration was not significantly associated with dental carries, after adjusting for confounders. However, sugar intake, older age, mothers’ unemployment, and not being in marital union are risk factors for dental caries development. Conclusions Promotion of healthy diet, especially limiting intake of sugar and sweets, and integration of oral health into primary health care programs are recommended. Further research using longitudinal design or meta-analysis is recommended to establish more concise evidence on the association between breastfeeding duration and dental caries.
