RESUMO
Objective@#To investigate the prevalence of depression and anxiety symptoms among middle school students in Taizhou, Zhejiang Province, and its associations with their educational burden, so as to provide a theoretical reference for making more targeted psychological interventional measures.@*Methods@#A cross sectional study was conducted by multi stage cluster sampling from September to November 2022 from 30 schools in five districts and counties of Taizhou, with a final sample of 8 128 junior and senior high school students completing the online surveys on the Questionnaire Star platform. The Educational Stress Scale for Adolescents (ESSA) was used to measure academic stress; the Child Depression Inventory (CDI) and the Generalized Anxiety Disorder Scale (GAD-7) were used to screen students depression and anxiety, respectively. The relationships between educational burden and depression and anxiety symptoms were analyzed by Logistic regression models.@*Results@#The prevalence of depression and anxiety were 19.3% and 11.1%, respectively. The average score of middle school students study pressure was (52.8±11.5). The number of extracurricular classes was <1, the time length of extracurricular courses was <1 hour per day, and students averagely spend 3.6 hours per day on homework assigned by school teachers. Nearly 30.0% students had ≤0.5 of discretionary time school days and 28.5% students had ≤2 on weekends. About 30.8% students though they do worse in their academic performance. According to the results of binary Logistic regression analysis, after controlling the demographic variables, the score in Study Pressure Scale, the number of extracurricular classes, the volume of homework and the time length of extracurricular courses were positively associated with depression and anxiety ( OR =1.09, 1.07, 1.08, 1.05, 1.04, 1.08, 1.08, 1.08, 1.06, 1.09, 1.07, 1.47, 1.34, 2.84 ; 1.08, 1.06, 1.08, 1.04, 1.03, 1.05, 1.05, 1.05, 1.05, 1.07, 1.06, 1.48, 1.23, 1.75, P <0.05). Students with overage grades had a higher risk of depression symptoms ( OR=1.34, P <0.05).@*Conclusions@#Academic burden has negative effects on depression and anxiety of students in Taizhou. It is advisable to alleviate academic stress, so as to improve the mental health of students.

Objective@#To analyze the prevalence of obesity and its influencing factors among residents aged 40 years and over in Taizhou,so as to provide reference for obesity prevention and control. @* Methods@#From June 2014 to May 2015,people who were aged 40 years or above and received routine physical examination in six centers for disease control and prevention in Taizhou were recruited. Demographic characteristics and health relates behaviors were collected by a questionnaire survey;height,weight,waist circumference and hip circumference were collected by physical examination. Logistic regression analysis was conducted to explore the influencing factors for overall obesity and central obesity.@*Results @#Totally 1 216 people were investigated,and 1 192 (98.03%) questionnaires were valid. The age of them ranged from 40 to 86 years old,with （51.92±8.91） years old on average. There were 547 males （45.89%） and 645 females （54.11%）. The prevalence rates of overall obesity and central obesity were 6.54% and 60.32%,respectively. The Results of multivariate logistic regression analysis showed that regular physical exercise （OR=0.597, 95%CI： 0.359-0.992） was a protective factor for overall obesity;female （OR=2.352,95%CI： 1.685-3.283）was a risk factor of central obesity;public servants or staff from enterprise and institution（OR=0.508, 95%CI： 0.289-0.892）,drinking （OR=0.637,95%CI：0.471-0.860）,salt intake of less than five grams per day （OR=0.590,95%CI：0.434-0.802）and regular physical exercise （OR=0.760,95%CI：0.583-0.991） were protective factors for central obesity. @*Conclusion @#The prevalence rates of overall obesity and central obesity among residents aged 40 years or above in Taizhou were 6.54% and 60.32%, respectively. Gender,occupation,drinking,salt intake and physical exercise were the influencing factors for obesity.
RESUMO
<p><b>UNLABELLED</b>Obstract: To characterize and analyze risky sexual networks and genetic scales to potential HIV transmission for HIV seroconcordant couples in Taizhou municipality of Zhejiang Province.</p><p><b>METHODS</b>HIV seroconcordant positive couples were invited as index cases to participate in an egocentric survey on HIV related risky behavior and behavioral network prior to HIV diagnosis during 2008-2011. Within-couple HIV transmission pairs were determined by the combination of both behavioral and phylogenetic analysis.</p><p><b>RESULTS</b>Totally 27 HIV seroconcordant couples were enrolled in this study. Male spouses were more likely to report having two or more sexual partners in the past years prior to HIV diagnosis than female spouses (88.9% vs. 37.0%). Among 27 couples, 20 couples including 17 couples by male but not female spouses, 3 couples by female but not male spouses reported having two or more sexual partners (i.e., multiple sexual partners) prior to HIV diagnosis; and 7 couples by both spouses reported having multiple sexual partners. Twenty four of 27 sexual networks were determined to be HIV transmission pairs (20) or potential transmission pairs (4), 3 couples were subtyped with discordant HIV subtypes or large genetic distance and thus had different sources of HIV transmissions. In addition, among 27 concordant couples, HIV drug resistance (HIVDR) or primary HIVDR existed in 6 ART-naïve participants in 4 networks; among them, 2 networks were determined to be potential HIVDR transmission couple pairs.</p><p><b>CONCLUSIONS</b>The HIV strains isolated in HIV infected spouses characterized with diversity and CRF01_AE was the main strain subtype. One of the spouses with risky behavior infected HIV was the main route of transmission to other spouses through unprotected sexual contacts. HIVDR was isolated from some HIV infected individuals, suggesting the risk for HIVDR transmission in married couples. The results provide enhanced evidence for urgent development of tailored prevention strategies, such as couple-based HIV counseling and testing services to reduce HIV secondary transmission.</p>
