RESUMO
BACKGROUND: Depression is being increasingly acknowledged as a global public health concern, and following this trend, attention towards eating disorders (EDs) has surged within China's national consciousness. EDs symptoms frequently coexist with various mental health conditions, including depression. However, research focusing on EDs symptoms and depressive symptoms among Tibetan students in China remains scant. This study employs network analysis to estimate the relational network between EDs and depressive symptoms. METHODS: Tibetan (n = 2,582) and Han (n = 1,743) students from two universities in the Xizang Autonomous Region, China, completed the Eating Attitude Test-26 (EAT-26) and the Patient Health Questionnaire-9 (PHQ-9). We estimated the network structure of EDs symptoms and depressive symptoms, identified central and bridge symptoms, and examined whether network characteristics differed by gender and ethnic. RESULTS: The core symptoms identified within this study were Calorie_awareness, Desire_to_thin and Fatigue. Conversely, bridge symptoms included Appetite, Suicide, Anhedonia, Guilty, Body_fat_awareness, and Food_preoccupation. The study also revealed no significant gender differences within the network model. However, disparities among ethnic groups were observed within the network structure. CONCLUSIONS: Our study examined the correlation between EDs symptoms and depressive symptoms in Tibetan college students. Focusing on the individual's quest for the perfect body shape and some Tibetan students' appetite problems - potentially stemming from transitioning to a new university environment, adapting to the school canteen's diet, or being away from their hometown - could aid in the prevention and management of EDs and depression symptoms. It could reduce the incidence of complications by helping students maintain good physical and mental health. Concurrently, our research provides insights into the relatively higher levels of depression triggered by the unique plateau environment.

OBJECTIVE: To determine serum levels of betatrophin in patients with polycystic ovary syndrome (PCOS) and the influential factors. â© METHODS: A total of 100 PCOS patients were enrolled randomly as a PCOS group, and 40 age-matched healthy women were recruited as a normal control (NC) group. Primary clinical or biochemical parameters of the subjects were detected. The results were analyzed by SPSS 19.0.â© RESULTS: Serum betatrophin levels were elevated in the PCOS group compared with the NC group. Serum betatrophin levels were positively correlated with age and Whole Body Insulin Sensitivity Index (WBISI),and negatively correlated with body mass index, fasting insulin(FINS), homeostatic model assessment insulin resistance (HOMA-IR) and homeostatic model assessment ß cell function (HOMA-ß). Multiple linear stepwise regression analysis showed that age and waist hip ratio (WHR) were independent influential factors for the level of betatrophin. PCOS was more likely to occur in women with higher betatrophin levels.â© CONCLUSION: Serum betatrophin levels increase in women with PCOS and they are independently associated with age and WHR. There is no significant correlation between betatrophin and insulin resistance or insulin levels.
