Breastfeeding Measurement - Considerations When Measuring Exclusive Breastfeeding.

Abstract

Exclusive breastfeeding, as recommended by the World Health Organization (WHO) for the first 6 months of life, is a critical metric for evaluating maternal and infant feeding practices and health outcomes. Despite its importance, inconsistencies in defining and measuring breastfeeding exclusivity present challenges for research comparability and interpretation. Equally, research design, outcomes of interest, and study resources are necessary considerations when collecting and analyzing exclusive breastfeeding data, and may require the adaption of standardized questions and techniques to individual situations. This paper explores key considerations for researchers when operationalizing and measuring exclusive breastfeeding. We address the nuances of point prevalence and since-birth measures, highlighting their influence on study outcomes and data interpretation. Statistical approaches for analyzing exclusivity data, including logistic regression, survival analysis, and Kaplan-Meier methods, are also discussed. By outlining best practices for precise definitions, tailored data collection, and transparent reporting, this paper aims to provide an overview for precise definition, effective data collection, and clear interpretation.
