Objective:To explore the heterogeneity in the trajectories ofperinatal depressive symptoms and identify the related factors.Methods:A longitudinal follow-up study was conducted from January 2020 to June 2021.Baseline information,marriage satisfaction and social support status were collected at enrolment.Perinatal de-pressive symptoms were measured using the Edinburgh Postnatal Depression Scale(EPDS)at five time-points from second trimester to three-months postpartum.A Latent Class Growth Model(LCGM)was used to identify sub-groups of perinatal depressive symptoms trajectories and logistic regression was applied to examine associated risk and protective factors.Results:Two latent depression trajectory subgroups were identified A majority(72.2％,n=1 023)followed a curvilinear trajectory with low baseline scores that increased over time(curvilinear group),while 27.8％(n=393)maintained high,stable scores(linear group).Older age,higher marital satisfaction,and stronger social support were associated with a lower likelihood of belonging to the linear group(OR=0.96,0.94,0.89,re-spectively),while a personal or family history of depression increased this likelihood(OR=2.50,6.51).Conclusion:Trajectories of perinatal depressive symptoms vary significantly among individuals.The risk of persis-tent high-level symptoms is lowered by older age,stronger marital satisfaction,and greater social support,and heightened by a personal or family history of depression.

AIM: To understand the influence of national constitution monitoring on sports behavior, attitude and physique of the investigators. METHODS: The study was performed at the Constitution Monitoring Center of Chenzhou Sports Bureau from March to December 2005. 285 public servants of Chenzhou were enrolled as investigators for the first study in 2005 and the second after 10 mouths with questionnaire. Age was accorded with the first measurement. 283 valid data were included (168 males and 115 females), because 2 could not participate in the constitution measurement. Questionnaire in 2006 involved individual physical awareness, behavior, attitude, participating rate, and whether doing the questionnaire according to the physical exercise prescription in the first monitoring. RESULTS: Significant differences in cardiovascular function, strength and sensitivity were detected between testees and national average value, especially in males and middle-age persons and youth. Nine months later, significant difference was found after paired test, step test and in vital capacity improvement. Improvement in other indexes had differences in age and sex. CONCLUSION: The measurement on national constitution is good for realizing their own state of health, improving their sports consciousness, increasing their frequency of doing sports greatly, and improving the physical state, especially for middle-aged and elder persons.
