Examining the relationship between family meal frequency and individual dietary intake: does family cohesion play a role?

OBJECTIVE

To confirm previously reported associations between family meal frequency and dietary intake, and to examine family cohesion as a potential mediator of this relationship.

DESIGN

Cross-sectional observational study. Data collected at baseline via questionnaire.

SETTING

Randomized, controlled household weight gain prevention trial.

PARTICIPANTS

Participants were 152 adults and 75 adolescents from 90 community households.

VARIABLES MEASURED

Family meal frequency assessed with a single question. Perceived family cohesion measured by the Family Adaptability and Cohesion Evaluation Scale-III. Usual intake of targeted food items assessed with modified food frequency questionnaire.

ANALYSIS

Hierarchical linear regression with mediation analysis. Statistical significance set at α-level .05.

RESULTS

Family meal frequency was associated with intake of fruits and vegetables in adults, and sweets and sugar-sweetened beverages in adolescents. Family meal frequency was positively correlated with perceived family cohesion (r = 0.41, P < .01). Partial mediation by family cohesion was observed for family meal frequency and sweets intake in adolescents.

CONCLUSIONS AND IMPLICATIONS

Results suggest that family cohesion is not a consistent mediator of relationship between family meal frequency and individual dietary intake. Future studies should assess additional plausible mediators of this relationship in order to better understand the effect of family meals on dietary intake.
