The studies were published between 1993 and 2017, with 2886 participants, of which 912 are cases and 1974 are controls. Meta-analysis of included studies revealed a significant difference between groups in depression outcomes (DMP: 0.75; 95 % CI: 0.41 to 1.10; p < 0.0001; I2: 28 %), anxiety (DMP: 1.22; 95 % CI: 0.84 to 1.59; p < 0.00001; I2:0%) and somatization (DMP: 1.31; 95%CI: 0.80 to 1.82; p < 0.00001; I2: 46 %).Through the meta-analyses, significant associations were observed between vulvodynia and depression, anxiety and somatization.
