Although several studies have investigated the association between Internet use and odds of overweight and obesity, results are inconsistent. This systematic review and meta-analysis was performed to summarize evidence on the association between Internet use and odds of overweight and obesity. A systematic literature search was conducted in PubMed/Medline, Web of Science, Scopus, and Google Scholar up to February 2019 to identify relevant publications. Finally, 9 cross-sectional studies were considered in this systematic review and meta-analysis. Combining 11 effect sizes from 9 studies, we found a significant, positive association between the highest Internet use, compared to the lowest (ranged from ≥5 h/d to no use among studies), and odds of overweight and obesity (OR: 1.47; 95% CI: 1.21–1.78; I2, 69.6%; P< 0.001), such that Internet users had 47% greater odds of being overweight or obese. We also observed a significant, positive association between the highest Internet use, compared to the lowest (ranged from ≥5 h/d to no use among studies), and overweight/obesity (OR: 1.15; 95% CI: 1.06–1.25; I2, 0.0%; P= 0.426), obesity (OR: 2.58; 95% CI: 1.88–3.54; I2, 0.0%; P= 0.637), and overweight (OR: 1.38; 95% CI: 1.16–1.64; I2, 13.1%; P= 0.330). A linear dose-response meta-analysis revealed that each additional 1 h/d of Internet use was associated with 8% increased odds of overweight and obesity (OR: 1.08; 95% CI: 1.05–1.11; I2, 3.8%; P= 0.403). Findings of this systematic review and meta-analysis indicated that Internet use was positively associated with increased odds of being overweight and obese.
