Abstract

Background: Accurate measurement of exclusive breastfeeding is important in maternal and child health research. Exclusive breastfeeding is often measured using the 24-hour recall or the since birth method for the first 6 months. These methods can produce different estimates, introducing problems in interpreting breastfeeding behavior and making accurate comparisons across settings or countries.

Research Aim: Our aim was to compare the exclusive breastfeeding rates between the 24-hour recall and since birth methods among a diverse cohort of birthing people using the ecological momentary assessments method. In addition, we compared the exclusive breastfeeding rates between the two methods across race and other maternal characteristics.

Methods: This study is a secondary analysis using data from the Postpartum Mothers Mobile Study (PMOMS), a prospective longitudinal study which recruited participants during pregnancy and followed them for 12 months after delivery. Participants completed surveys in real-time via ecological momentary assessment. Individual exclusive breastfeeding rates from months 1-6 were computed using 24-hour recall and since birth methods for 284 participants. We calculated the percentage point difference between the two methods across child age and maternal characteristics. We used a two-sample test of proportions to determine if the differences observed in the proportions were significant.

Results: Exclusive breastfeeding rates from the 24-hour recall were higher than the since birth rates across all ages and maternal characteristics. The difference between the two methods at 3 months was 25.7 percentage points and at 6 months was a 17.2 percentage points. Irrespective of the method used to measure exclusive breastfeeding, White participants had higher exclusive breastfeeding rates than Black participants.

Conclusion: The 24-hour recall and the since birth methods of assessing exclusive breastfeeding provided substantially different estimates. These findings highlight the importance of specificity in measuring and reporting exclusive breastfeeding.
