| Summary: | The study had several limitations, including: ○ Key confounders were not accounted for.○ Data were from a multi-component randomized controlled trial that was not designed to test frequency of eating.○ One prospective cohort study with critical limitations was not sufficient to draw conclusions BACKGROUND: 1. This important public health question was identified by the U.S. Departments of Agriculture (USDA) and Health and Human Services (HHS) to be examined by the 2020 Dietary Guidelines Advisory Committee.2. The 2020 Dietary Guidelines Advisory Committee, Frequency of Eating Subcommittee conducted a systematic review to answer this question with support from the Nutrition Evidence Systematic Review (NESR) team.3. The goal of this systematic review was to examine the following question: What is the relationship between the frequency of eating during lactation and postpartum weight loss? CONCLUSION STATEMENT AND GRADE: 1. Insufficient evidence is available to determine the relationship between the frequency of eating during lactation and postpartum weight loss. (Grade: Grade not assignable) METHODS: 1. A literature search was conducted using 4 databases (PubMed, Cochrane, Embase, and CINAHL) to identify articles that evaluated an intervention or exposure of the frequency of eating and the outcome of postpartum weight loss. A manual search was also conducted to identify articles that may not have been included in the electronic databases searched. Articles were screened by two authors independently for inclusion based on pre-determined criteria.2. Data extraction and risk of bias assessment were conducted for each included study, and both were checked for accuracy. The Committee qualitatively synthesized the body of evidence to inform development of a conclusion statement(s), and graded the strength of evidence using pre-established criteria for risk of bias, consistency, directness, precision, and generalizability. SUMMARY OF THE EVIDENCE: 1. Frequency of eating was defined as the number of daily eating occasions. An eating occasion was defined as an ingestive event (solid food or beverage, including water) that is either energy yielding or non-energy yielding.2. Postpartum weight loss was defined as a change in weight from baseline (postpartum) to a later time point during the postpartum period. Additionally, it could be postpartum weight retention, if gestational weight gain was controlled for in the analysis.3. This review included 1 prospective cohort study (using data from a multicomponent RCT) that met the inclusion criteria for this systematic review and was published within the date range of January 2000 and September 2019.4. The 1 included study did not report a significant association between a change in eating frequency and a change in weight from baseline over a 12-week follow-up.5. |
