Family Meal Frequency, Diet, and Family Functioning: A Systematic Review With Meta-analyses

Abstract

ObjectiveTo examine the direction and magnitude of the relation between family meal frequency and dietary and family functioning outcomes in children (aged 2–18 years). DesignSystematic literature review with meta-analysis. MethodsIndependent electronic searches, 1 for each outcome of interest, were conducted across 5 databases: PubMed, Cumulative Index to Nursing and Allied Health Literature, Web of Science, Scopus, and PsycINFO. Studies were included if they were peer-reviewed and published in English in the US through December 2018. Main Outcome MeasuresDiet and family functioning. ResultsDietary 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 was less clear evidence of this relation in snacks, fast food, and desserts. A positive association was found between family meal frequency or dinner family meal frequency and family functioning outcomes. All studies included had cross-sectional and longitudinal study designs. Conclusions and ImplicationsThere is some evidence to show a positive relation between family meal frequency and dietary outcomes. There is stronger evidence for the relation with family functioning outcomes. Most articles included in the systematic reviews were excluded from meta-analysis owing to inadequate data and high methodological diversity across exposure and outcome variables.
