Association between circulating vaspin levels and the risk of gestational diabetes mellitus: A systematic review and Meta－analysis / 中华疾病控制杂志

ABSTRACT

@#Objective To review the existing literature and quantitatively evaluate the association of circulating vaspin levels and the risk of gestational diabetes mellitus ( GDM) ． Methods We systematically searched the PubMed，EMBASE，Web of Science，China National Knowledge Infrastructure，and WanfangData databases up to June 2019． Pooled standardized mean differences ( SMDs) with 95% confidence intervals ( CIs) were calculated using random－ or fixed－effects models based on the heterogeneity of studies． Subgroup analyses，Meta－regression，sensitivity and publication bias were assessed to analyze the heterogeneity and the robustness of the results． All statistical analyses were performed using STATA 12．0． Ｒesults Nine articles ( 11 comparisons) published from 2013 to 2019 were included in our final Meta－analysis，covering a total of 738 patients with GDM and 661 normal pregnant women． There was significant difference in the overall maternal circulating vaspin levels between GDM patients and healthy pregnant women ( SMD= 0．613，95% CI 0．044－1．182，P= 0．035) ． Subgroup analyses stratified by trimester in which vaspin was measured and whether BMI was matched suggested the similar trend to the overall result． Subgroup analysis according to ethnicity found that circulating vaspin level might not be related to GDM in " European" subgroup; sensitivity analysis by excluding moderate－quality studies and BMI－unmatched studies found that circulating vaspin levels were still related to GDM risk． Conclusions Our Meta－analysis indicated that maternal circulating vaspin levels might be positively correlated with the risk of GDM in Asians．
