Currently, no systematic review/meta-analysis has examined studies that used online social networks (OSN) as a primary intervention platform. Therefore the purpose if this review was to evaluate the effectiveness of weight management interventions delivered through OSN.
PubMed, Embase, PsycINFO, Web of Science, and Scopus were searched (January 1990-November 2015) for studies with data on the effect OSNs on weight loss. Only primary source articles that utilized OSN as the main platform for delivery of weight management/healthy lifestyle interventions, were published in English language peer-reviewed journals, and reported outcome data on weight were eligible for inclusion in this systematic review. Five articles were included in this review.
