LATCH Scoring System as a Predictor of Breastfeeding Duration
This paper reviews a 2006 prospective study by Kumar et al. published in the Journal of Human Lactation, which examined whether the LATCH scoring system — a standardized tool for assessing mother-infant breastfeeding technique — could predict breastfeeding duration. The study enrolled 250 new mothers at an urban hospital and followed up by telephone at four days and six weeks postpartum. Findings indicated that a LATCH score of 9 or above at 16 to 24 hours after birth was the strongest predictor of continued breastfeeding, with qualifying mothers 1.7 times more likely to still be breastfeeding at six weeks. The paper evaluates the study's methodology, identifies unaddressed variables such as maternal emotional state and instructor quality, and suggests directions for future research.

What makes this paper effective
- The paper clearly summarizes the original study's purpose, methods, and findings before moving into evaluation, giving readers sufficient context to follow the critique.
- It identifies specific methodological limitations — maternal emotional state, infant variability, and instructor effectiveness — rather than offering only generic criticism.
- The review connects the study to a broader public health goal (U.S. Healthy People 2010 targets), grounding the clinical tool in a meaningful policy context.
Key academic technique demonstrated
This paper demonstrates source-based critical evaluation: the writer accurately restates study findings, then applies independent judgment to assess what the study did well (two follow-up points, standardized tool use) and what variables it left unexamined. This move — acknowledge strengths before raising gaps — is a core pattern in academic research critique.
Structure breakdown
The paper opens with the public health rationale for breastfeeding promotion, introduces the LATCH tool and its history, summarizes the 2003 prospective study's design and data collection procedures, presents the numerical results, relays the authors' own interpretive discussion, and closes with an independent critique that proposes further study. The argument flows logically from context to evidence to evaluation.
Introduction and Public Health Context
Kumar, S. P., Mooney, R., Wieser, L. J., & Havstad, S. (2006). The LATCH scoring system and prediction of breastfeeding duration. Journal of Human Lactation, 22(4), 391–397.
The risks associated with not breastfeeding are well documented and include slow infant weight gain, failure to thrive, starvation, and in severe cases, death. Additional negative risk factors include flat or inverted nipples, greater use of non-breast-milk fluids, pacifier use, prolonged second stage of labor, and delayed onset of lactation. In response to these risks, the U.S. Healthy People 2010 initiative established specific targets: increasing the breastfeeding initiation rate to 75%, the six-month breastfeeding continuation rate to 50%, and the twelve-month rate to 25%. Achieving these goals has historically been met with varying degrees of success.
This study examined how effectively educating new mothers about latching during the postpartum hospital stay — ranging from 48 to 96 hours depending on whether the birth was vaginal or cesarean — could help healthcare workers predict whether a mother would successfully continue breastfeeding. The central question was whether the degree to which a baby is able to suck at the breast, as measured by the LATCH scoring system, could serve as a meaningful predictor of breastfeeding duration.
The LATCH Scoring System
The LATCH Scoring System was developed in 1994 to assist healthcare providers in systematically evaluating the breastfeeding techniques of mother-infant dyads. The tool provides a framework for standardized documentation and consistent communication among care providers. In 1997, Adams and Hewell established the reliability of the LATCH tool for professional breastfeeding assessment, using direct observation rather than videotape-based assessment methods.
Study Design and Methods
This prospective study was conducted from January to October 2003 at an urban hospital with a delivery rate of approximately 2,500 births per year. When expectant mothers arrived at the labor, delivery, and recovery suite, they were asked whether they planned to breastfeed. The duration of anticipated breastfeeding was not queried at that point. Following birth, mothers and newborns remained in the delivery suite for two hours after a vaginal delivery or in the postoperative recovery room following a cesarean delivery. During this period, breastfeeding and skin-to-skin contact were encouraged and attempted whenever possible. Two hundred fifty mothers were enrolled, representing a 79% agreement-to-participate rate.
A board-certified lactation consultant trained all nursing staff in the use of the LATCH tool and assessed their competency with it. The LATCH scoring system was incorporated into the newborn flow sheet to facilitate easy documentation. Scoring was performed at least once per eight-hour shift during the mother's hospital stay.
Data collected on maternal variables included age, gravidity, parity, ethnicity, level of education, mode of delivery, and type of anesthesia, as well as LATCH scores. For the newborn, data included birth weight, gestational age, and one-minute and five-minute Apgar scores. Post-discharge follow-up was conducted via telephone on day four and at six weeks postpartum. At each call, participants were asked whether they were still breastfeeding. For the purposes of data analysis, exclusive and partial breastfeeding were combined into a single "breastfeeding" category, while token breastfeeding and no breastfeeding were combined as "not breastfeeding."
