The association of breastfeeding duration and language development survey score in children

Background and objectives: Breastfeeding is an intimate moment between mother and children. Studies had shown the effectiveness of breastfeeding to stimulate cognitive function of children including their language development. We hypothesize the longer duration of breastfeeding the higher language ability of children. This study aimed to examine the association between breastfeeding duration and LDS score of children aged 18-35 months old. Our primary outcomes were LDS-vocabulary score and LDS-phrase score.  Methods: This cross sectional study was performed in 261 breastfeeding mothers with children aged 18-35 months old. A mother whose children diagnosed with delayed growth was excluded from the study. Data of breastfeeding duration (BF) and subjects’ characteristics were obtained through a questionnaire. Body mass index (BMI) of mother and weight-per age of children were collected for nutritional status. We applied language development survey (LDS) checklist form to assess vocabulary and phrase ability of the children. Statistical modelling was calculated by multiple logistic regression.Results: Prevalence of severe undernourished was highest in BF group 7-18 months vs 6 months vs >18 months old (13% vs 2% vs 4.6%, respectively). Neither LDS vocabulary nor LDS phase score have association with breastfeeding duration (p=0.973 and 0.937, respectively). Mother age, socioeconomic status, and siblingship might contribute to the association between BF duration and children language development (OR 0.63, 95% CI 0.25-1.61; OR 0.42, 95% CI 0.11-1.59, respectively).Conclusion: Breastfeeding duration is not a risk factor for delayed of children language development. This observation merits further investigation to explain the relationship between duration of breastfeeding and children language development with prospective approach

Breastfeeding Duration More than 18 Months Possibly Lowers the Risk of Language Development Delay in Children Aged 18–35 Months

Studies have demonstrated the benefits of breastfeeding (BF) on children’s cognitive function and language development. However, most cognitive and language tools used in these studies have limited ability to identify children’s language development delays. The Language Development Survey (LDS) is expected to provide detailed information on children’s language development. This study aimed to examine the association between BF duration and children’s LDS. A questionnaire was administered to 286 BF mothers to obtain information on their BF duration, and LDS was employed to assess children’s language development. Language delays were detected in 91 (31.8%) children (LDS-vocabulary) and 35.7% children (LDS-phrase). This study also found that children who were breastfed for ≤6 months and 7–18 months had an adjusted OR (AOR) of 0.86 of LDS-vocabulary, and 0.8 of LDS-phrase, whereas children who were breastfed for >18 months had AOR’s LDS-vocabulary of 0.57 and LDS-phrase of 0.46. This study found no significant association between BF duration and LDS score. Nevertheless, BF duration of >18 months possibly lowers the risk of children’s language development delay. More studies are required to investigate this observation’s relationship with children’s language development
