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.","journal":"Journal of Human Lactation","year":2023,"id":377534,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9525,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2023-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":879504,"name":"Patricia I.
