This study aimed to explore the trajectories of perinatal depressive symptoms, their heterogeneity of onsets and peaks, and relations to demographic and psychological factors. A longitudinal study was conducted at two hospitals in China amongst 1,126 participants. Perinatal depression was measured using the Edinburgh Postnatal Depression Scale. Demographic and psychological factors were collected by self-developed questionnaire and Generalized Anxiety Disorder-7. Women completing at least three depression screens (n=879) were included. Latent Growth Curve Model and Growth Mixture Model were performed to identify the depression trajectories and logistic regression was used to analyse factors of trajectories. Three trajectories were identified 90.0% of women never presented with depressive symptoms ("Low-throughout"); 5.1% presented with depressive symptoms mainly during the antenatal perid with each trajectory were different, raising the potential of individualized intervention to reduce the occurrence of depression.Despite recent growth, opportunities for preclinical medical students to engage with the field of wilderness medicine remain geographically, financially, and logistically limited. Attendees of the 2018 Mid-Atlantic Student Wilderness Medicine Conference were invited to complete a post hoc web-based survey after the event. Results of the survey were analyzed to determine the demographic characteristics and motivating factors for attendance, as well as perceived conference performance and future behavioral intention of survey respondents. The majority of attendees were preclinical level medical students, 37% of whom were affiliated with their institutions' wilderness medicine interest group and 40% of whom were affiliated with an emergency medicine interest group.
