RESUMO
@#Objective To explore the influence of reproduction history on depression during pregnancy． Methods Data on 3 792 pregnant women from the Chinese pregnant women cohort study with complete information on reproduction history and depression were used in the present study． The Edinburgh postnatal depression scale was used to assess depression status among pregnant women． A chi-square test was used for univariate analysis，and a Log－binomial regression was used for multivariate analysis． The adjusted relative risks ( ＲＲs) with 95% confidence intervals ( 95% CIs) were calculated，and were presented in a forest plot． Ｒesults The results of Log－binomial regression showed that a history of delivery could increase the risk of depression during the second trimester ( ＲＲ: 1. 04，95% CI: 1. 01 － 1. 08，P= 0. 042) and the third trimester ( ＲＲ: 1. 05，95% CI: 1. 01－1. 10，P= 0. 020) ． There was a 6% increase of risk on depression in women with a history of cesarean delivery compared with women without that during the third trimester ( ＲＲ: 1. 06，95% CI: 1. 01－1. 11，P = 0. 041) ． Conclusions There is asignificant influence of reproduction history on gestational depression． Maternal and child health personnel should focus on these pregnant women，and conduct targeted health education and mental nursing． In addition，medical personnel should also pay attention to the emotional changes of these women and provide them with several adjustment strategies．
RESUMO
Objective To study the current status and risk factors of spontaneous abortion of women with Tibetan ethnicity at reproductive age in rural areas.Methods Pregnant women who lived in fibet were interviewed on their former reproductive history and being followed on the outcomes of pregnant from 2006 to 2012.Generalized Poisson regression model was used to explore the influencing factors of spontaneous abortion.OR value of the research factors was estimated and its 95％ confidence interval counted.Results There were 1 557 pregnant women under this study,with a total number of 2 687 pregnancies and 2 382 productions.171 women underwent spontaneous abortion,with a total number of 204 times,93 women had histories of abortion,with a total number of 101 times.Among all the Tibetan pregnant women,the ratio between spontaneous abortion and pregnant women was 7.6％ while the rate of spontaneous abortion was 7.9％.Ratio between the number of women who had experienced spontaneous abortion and the total number of women under survey was 11.0％.Pregnancy appeared the important reason on spontaneous abortion.The risk of having spontaneous abortion would increase among women who had more than 3 pregnancies.Results from Poisson regression analysis revealed that the odds ratio (OR) value before the adjustment was 3.921 (95％CI:2.553-6.021) but after the adjustment,it increased to 4.722 (95％CI:2.834-7.866).The increase of production time could reduce the risk of spontaneous abortion in women of childbearing age.Risks related to spontaneous abortion were associated with the number of pregnancies.Women seemed to have lower risk for spontaneous abortion after 2009,with OR value as 0.419(95％CI:0.285-0.616) before,compared to aOR value as 0.580 (95％CI:0.380-0.885) after the adjustment Social-demographic characteristics was not found to be particularly associated with the occurrence of spontaneous abortion.Conclusion Rate of spontaneous abortion among Tibetan women at childbearing age was not particularly high when comparing to those women living in the plain area such as Shaanxi.However,in order to further reduce the incidence of spontaneous abortion among Tibetan women,approaches should include the following items:strengthening maternal health care,extending the spacing of pregnancy and reducing the frequency of pregnancy.
