Abstract
Objective: This paper presents a systematic review and meta-analysis of comprehensive information on the epidemiology of toxoplasmosis (TOX), rubella virus (RV), cytomegalovirus (CMV), and herpes simplex (HSV) also known as TORCH infection in women of childbearing age. Besides, the positive rates of TORCH-Immunoglobulin G (TORCH-IgG) and Immunoglobulin M (IgM) antibodies in women of childbearing age in different regions of China were statistically analyzed, so as to highlight the issue of TORCH infection in women of childbearing age. Methods: A total of 12,694 articles were retrieved by keyword searching. The works were screened according to the inclusion criteria, and 25 studies were included totaling 531,617 women of childbearing age. The OpenMeta[Analyst] software was used to perform a heterogeneity test, and a random-effects model was used for system analysis. Results: The results of the meta-analysis showed that the positive rates of TORCH-IgG antibodies in women of childbearing age nationwide were 3.2% for TOXIgG, 73.4% for RV-IgG, 73.8% for CMV-IgG, and 57.4% for HSV-IgG. The positive rates of IgM antibody infection in TORCH were 1.3% for TOX-IgM, 6.1% for RV-IgM, 9.5% for CMV-IgM, 7.6% for HSV-IgM, 2.0% for HSV-1-IgM, and 1.9% for HSV-2-IgM. All meta-analyses had I2 ≥ 98% and P < 0.001, which meant that the results were statistically significant. Conclusions: A meta-analysis of the positive rates of IgG and IgM antibodies of TORCH infection in women of childbearing age found that the early infection rate of HSV was the highest, and the previous infection rate of RV was the highest. This result can provide epidemiological basis for the prevention and treatment of TORCH infection.
