%X Many epidemiologic studies have been conducted to assess factors that were associated to endometriosis, but there is no consistency in results. Therefore, we conducted this meta-analysis to investigate the association between body mass index and the risk of endometriosis. In this meta-analysis, relevant studies that published in major international electronic bibliographic databases of PubMed, Scopus and Web of Science were systematically searched during November 2017. The Begg and Egger¡¯s test was used to investigate publication bias in included studies. The Q-statistic and I2 tests were carried out for measuring heterogeneity. The random-effects model was conducted to obtain pooled odds ratio. Our results showed a direct association between underweight and endometriosis in woman (odds ratio£¿=£¿1.41, 95% confidence interval£¿=£¿1.16¨C1.66), so underweight woman had 41% higher chance for endometriosis. However, we did not find linear association between overweight and endometriosis (odds ratio£¿=£¿0.95; 95% confidence interval: 0.72¨C1.18) and obesity and endometriosis (odds ratio£¿=£¿0.88; 95% confidence interval: 0.54¨C1.21), respectively. Our results suggested that underweight was a risk factor for the endometriosis, while overweight and obesity were not protective factors for endometriosis
