Objective: To examine the direction and magnitude of the relationship between family meal frequency and dietary and family functioning outcomes in children (2-18 years).Design: Systematic literature review with meta-analysis.Methods: Independent electronic searches, one for each outcome of interest, were conducted across five databases PubMed, CINAHL, Web of Science, Scopus and PsycINFO. Studies were included if peer-reviewed and published in English in the US through December 2018.Main Outcome Measures: Diet and family functioning.Results: Dietary outcomes showed some evidence of a positive association between family meal frequency and fruits, vegetables, fruits and vegetables, sugar-sweetened beverages, and the Healthy Eating Index. There is less clear evidence of this relationship in snacks, fast food and desserts. A positive association was found between family meal frequency or dinner family meal 3 frequency and family functioning outcomes. All studies included had cross-sectional and longitudinal study designs.
Conclusions and Implications:There is some evidence to show a positive relationship between family meal frequency and dietary outcomes. There is stronger evidence for the relationship with family functioning outcomes. The majority of articles included in the systematic reviews were excluded from meta-analysis due to inadequate data and high methodological diversity across exposure and outcome variables.
