Dietary interventions using Facebook: a systematic review

Vera Cunha et al. Porto Biomed J. .

Abstract

Introduction: Facebook has been used to change food behaviors. The aim of this review was to synthesize the knowledge about the effect of nutritional interventions delivered through Facebook in dietary intake, food and nutritional knowledge and behavior, and weight management.

Methods: PubMed, Web of Science, Ovid, Scopus, and Cochrane electronic databases were searched for intervention studies that were published from 2013 to 2019. This systematic review protocol was formulated based on Cochrane Guidelines for Systematic Reviews of Health Promotion and Public Health Interventions and Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA).

Results: Of the 4824 identified studies, 116 were considered for eligibility and 18 met the inclusion criteria of this review. Of these, 13 were randomized controlled trials, 2 were quasiexperimental studies, 2 were case studies, and 1 was a nonrandomized controlled trial. Interventions had a positive nutritional-related impact in most of the studies (78%).

Discussion: Positive changes in dietary intake, food and nutritional knowledge and behavior, and weight management were observed in studies that used Facebook as a component of intervention. Facebook effectiveness by its own was difficult to evaluate considering that is frequently a component of intervention. The heterogeneity of the outcome variables between studies did not allow concluding about the effectiveness of this tool.

Keywords: Facebook; dietary intake; dietary interventions; nutritional knowledge; weight management.
