Abstract: ［Abstract］Objective To investigate the depression status and influencing factors for the late pregnancy women， and provide a theoretical basis for psychological consultations and interventions. Methods A symptoms of depression self rating scale（SDS）and a questionnaire for the basic information were adopted in the cross-sectional survey for 180 late pregnancy women at 35 weeks or more in the obstetrics of the second affiliated hospital of Kunming Medical University from March to May in 2015. Logistic regression analysis was used to explore the related risk factors of depression. Results The depression positive rate of late pregnancy women was 42.2%，among which the depression positive rate of the Han nationality（47.45%）was obviously higher than national minority's （25.58%），and Bachelor degree or above （52.94%） was higher than Bachelor degree and below（35.71%）. Logistic regression analysis showed that the risk factors for depression symptoms were nationality（OR=2.92，95%CI: 1.29-6.63），education（OR=3.29， 95%CI: 1.22-7.18），satisfaction degree of current marital status （OR=3.53， 95%CI: 1.09-6.24），and sleep time of every day（OR=0.37，95%CI:0.15-0.94）. Conclusion The present mental health status of the late pregnancy women in Kunming was poor，especially the pregnant women with Bachelor degree or above and poor quality of sleep，who were prone to depression. Extensive health education should be launched to pregnant women in order to reduce the possibility of depression during pregnancy.
