[Serological survey on infection in pregnant women with history of adverse pregnancy in Bazhou area, Hebei Province].

OBJECTIVE

To investigate the infection status in pregnant women with history of adverse pregnancy and risk factors in Bazhou area, Hebei Province.

METHODS

A total of 302 pregnant women with the history of adverse pregnancy were chosen as respondents (an experimental group) in the hospital from March 2012 to December 2015, and 197 pregnant women without the history of adverse pregnancy as a control group. TOX-IgG and TOX-IgM were detected by using ELISA in two groups. The risk factors of infection were surveyed by questionnaires.

RESULTS

The total positive rate of antibodies was 28.15% (85/302) in the experimental group, which was significantly higher than that [9.64%(19/197)] in the control group, and the difference was statistically significant ( = 24.76, ＜0.05). The positive rates of TOX-IgM, TOX-IgG and TOX-IgM + TOX-IgG were 6.95% (21/302), 18.54% (56/302), and 2.65% (8/302) respectively in the experimental group, which were higher than 2.03% (4/197), 7.61% (15/197), and 0% (0/197) respectively in the control group ( = 6.07, 11.67, 3.76, ＜0.05). The questionnaire survey showed that the proportions of keeping pets, cutting board regardless, liking to eat hot pot or barbecue, eating raw meat, often eating in the restaurant in the pregnant women with infection were higher than those in the pregnant women without infection, and the differences were statistically significant ( = 22.57, 3.96, 5.87, 7.40, 4.86, all ＜0.05), and therefore, the above unhealthy habits may be important risk factors.

CONCLUSIONS

infection could lead to adverse pregnancy outcomes. Therefore, the above-mentioned unhealthy habits should be avoided, especially during pregnancy period.
