Objective: To understand the dietary nutritional status of AIDS orphans aged 7-12 in Urumqi, and to provide a scientific basis for promoting growth, development and health. Methods: Using a random sampling method, a total of 309 children aged 7-12, from Urumqi were selected. The sample included 98 orphans with AIDS, 66 orphaned children not affected by AIDS, and 145 cases of non orphaned children. A 24 hour diet review method was used to record the diet of all three groups of children who received three meals per day, energy levels and the nutrient intake of AIDS orphans and their attainment were analyzed according to the daily recommended nutrient intake (RNI) of Chinese residents. Results: The detection rate of wasting in the AIDS orphans group was 44.9%, which was higher than that in the orphans without AIDS group (40.9%) and the non orphaned group ( 28.2 %); the overweight rates of AIDS orphans and orphans without AIDS were 3.1% and 3.0%, respectively, which were both lower than those of non orphaned children (8.3%); the average daily intake of energy and dietary nutrients in the AIDS orphans group was lower than that in the other two groups, and the intake of vitamin A, vitamin B 2, vitamin B 6, vitamin C,vitamin D, folic acid, calcium, zinc, and iron was seriously insufficient, the intake of food grains, vegetables, fruit, eggs, milk and dairy products, and the average daily intake of oil was lower among AIDS orphans than orphans without AIDS and non orphaned children, additionally,except for food grains,eggs, there were significant differences between the three groups ( F =3.02，5.23，27.86，16.59， P <0.05), and the daily intake of vegetables, aquatic products, eggs and milk in AIDS orphans and orphans was lower than the recommeded intake. Conclusion A higher rate of wasting, unbalanced nutrient intake, and poor nutritional status was found among AIDS orphans aged 7-12 in Urumqi. Therefore, there is a need to improve the dietary structure of AIDS orphans with the aim of promoting healthy development.

Objective To investigate the mental health level and stressors of medical students in a university in Xinjiang in the con-text of healthy China and analyzing their influencing factors.Methods From February to April 2021,a stratified cluster random sampling method was used to select 4421 medical students from a university in Xinjiang.Questionnaires were administered using Symptom Check List 90(SCL-90)and the Stressor Scale for Contemporary College Students.Results 25.26％medical survival in varying degrees of SCL-90scale listed symptoms;SCL-90scores on all factors were lower than the national norm for university students in some regions,the SCL-90scale scores for somatization,obsessive-compulsive symptoms,depression,and terror factors were significantly higher for girls than for boys(P＜0.05);the main stressors were developmental distress type;students from outside the Xinjiang had higher scores on developmental distress stressors than students from inside the Xinjiang(P＜0.05);girls were more stressed than boys,female students scored higher on developmental distress,personal management,and negative event stressors than male students(P＜0.05).Pearson cor-relation analysis showed that students'mental health level was positively correlated with the source of pressure(P＜0.05).Conclusion In a university in Xinjiang,25.26％of medical students had different degrees of mental health problems,and the mental health level of fe-male students was inferior to that of male students.Mental health level is positively correlated with stress,and developmental distress stress is the main source of stress for medical students.There are some differences in mental health level and stressors of medical students with different characteristics.

ObjectiveTo investigate the incidence and influencing factors of postpartum depression and anxiety in Urumqi during the coronavirus disease （COVID-19） epidemic period in 2020. MethodsResearch subjects were the parturients who underwent postpartum health checkups in a third class hospital in Urumqi from January 2020 to December 2020. The maternal socio demographic and obstetric information were collected， and PHQ-9 and GAD-7 scales were used for screening of PPD and PPA. Calcaneal bone mineral density of the parturients was measured by French Pegasus ultrasonic bone densitometer. After univariate analysis of the related influencing factors of PPD and PPA， multivariate binary logistic regression analysis was used to explore the relationship between mental disorders and various influencing factors. ResultsA total of 2 490 puerpera participated in the survey. The incidences of PPD and PPA in 2020 were 13.4 % and 10.8 %， respectively. Six factors with statistical differences after univariate analysis were included in multivariate binary logistic regression analysis. The final results suggested that age over 35 （OR=1.707，95%CI：1.142‒2.551）， unemployment （OR=1.478，95%CI：1.003‒2.205）， multipara（OR=1.340，95%CI：1.037‒1.733）， bone loss and osteoporosis （OR=1.434，95%CI： 1.076‒1.910） were the risk factors of PPD， while breastfeeding （OR=0.466，95%CI： 0.301‒0.721） was a protective factor. Ages between 18‒24 （OR=1.559，95%CI：1.282‒3.097） and cesarean section （OR=1.433，95%CI： 1.105‒1.859） were the risk factors of PPA， while ages between 30‒34 years old （OR=0.524，95%CI： 0.332‒0.827）， occupation as medical staff （OR=0.282，95%CI： 0.807‒0.919）， breastfeeding （OR=0.530，95%CI： 0.330‒0.850） were protective factors. ConclusionIncidences of PPD and PPA are in middle-low levels during COVID-19 epidemic period. Age， occupation， delivery mode， delivery times， feeding pattern and bone mineral density are the influencing factors. Screen coverage of PPD and PPA in special period should be strengthened， and measures should be taken to reduce the risk.
