Background : International authorities recommend prolonged breastfeeding (PBF) for 12?24 months or more with 6 months of exclusive breastfeeding (EBF). Based on the Korean National Health and Nutrition Examination Survey (KNHANES) data, this study attempted to help encourage and educate breastfeeding (BF) over 1 year by investigating long-term BF trends and related factors in Korean infants and their mothers.
Methods : This cross-sectional study was based on data on children aged 12?23 months and their mothers from 2010 to 2020. BF rates were compared between KNHANES V (2010?2012), KNHANES VI (2013?2015), KNHANES VII (2016?2018), and part of KNHANES VIII (2019?2020). In addition, data related to mothers and infants, including demographics, socioeconomic, educational, and health status, were collected, and their association with BF status was analyzed.
Results : Of the 933 infants included in the study, the proportions achieving full BF at 6 months of age and PBF at 12 and 18 months were 34.8%, 33.7%, and 7.1%, respectively. Over the past 10 years, the trends of all three BF practices have significantly decreased since 2016 (P < 0.001). Of the 849 infants whose maternal data were available, multiple logistic regression analysis showed that EBF for 6 months (defined as full BF at 1, 3, and 6 months of age) positively correlated with maternal and infants’ factors such as unemployed status, past BF experience, no history of drinking, and infants’ birth weight of ≥ 2.5 kg. The mother’s education level, particularly the nutrition label impact, current employment status, and smoking and drinking status, were significantly associated with PBF for ≥ 12 months but were not related to PBF for ≥ 18 months, except for drinking status.
Conclusions : In Korea, the long-term BF rate of ≥ 12 months has declined in the past 10 years, and BF becomes rare after 18 months. Higher maternal interest in nutrition information appears to be driving access to PBF over 12 months than EBF for 6 months or PBF over 18 months. To promote PBF over 12 months in Korea, it may be helpful to strengthen nutrition education that specifically emphasizes the benefits of PBF along with EBF, especially during infant health examinations.
