Abstract

Aim: The purpose of the present study was to assess the relationship of sex hormone binding globulin (SHBG) and gestational diabetes mellitus (GDM). Methods: The Cochrane Library, Medline, ScienceDirect, and Web of Science were searched for studies published from the inception of the databases up to February 2019. Our inclusion criteria were published observational full-text articles. All data were analyzed using Review Manager 5.3. Of 208 papers reviewed, 26 studies (n = 6668) were considered for meta-analysis. Results: The SHBG level was significantly lower in women with GDM compared to healthy women (MD = −11.86; 95% CI: [−13.02, −10.71]). Also, SHBG in women with PCOS and GDM and obesity was significantly lower than women with PCOS without GDM (MD = −38.14; 95% CI: [−56.79, −19.48]) and normal weight women (MD: −58.96; 95% CI: [−79.32, −38.59]). SHBG in the second trimester was lower than that in the first trimester and pre-conception. Conclusions: This systematic review showed that the level of SHBG is significantly lower in GDM pregnant women than that in healthy women. The results of this systematic review about the relationship of GDM and SHBG and suggestion to assess this marker in early pregnancy should be considered with caution. © 2019 Elsevier B.V.
