BACKGROUND AND PURPOSE: The global rise in social media usage has led to an increasing prevalence of social network problematic use or addiction (SNPUA). Although previous research has identified a negative association between physical activity (PA) levels and some problematic digital behaviors, the relationship between PA and SNPUA remains unclear. Thus, the aim of this systematic review and meta-analysis was to examine possible associations between PA and SNPUA.

METHODS: The search was registered in OSF and was conducted in November 2024 using the following search terms: ('Physical activity' or exercise) and (addiction or 'problematic use') and ('social network' or 'social media' or Instagram or Facebook or 'Tik Tok'). It was carried out in PubMed and Web of Science databases. A total of 255 articles were retrieved and 24 of them met the inclusion criteria. Meta-analysis was conducted using Review Manager 5.4 software.

RESULTS: The majority of studies included university students (n = 14) and primary or secondary school students (n = 7). The participants' mean age ranged from 13.9 to 27.43 years. Female participants accounted for 50.8 % of the total sample. The meta-analysis involving 150,000+ participants revealed that PA is inversely related to SNPUA. Most of the included studies (14/24), involving 94 % of the sample, reported that those participants who engage in a higher amount of PA had lower levels of SNPUA.

CONCLUSION: PA could be an effective tool to prevent or reduce social network addiction levels. However, inconsistency in collecting data on PA and SNPUA makes it difficult to draw solid conclusions.
