Doxycycline prophylaxis for sexually transmitted infections prevention among men who have sex with men in China
Background: Men who have sex with men (MSM) have a high prevalence of sexually transmitted infections (STIs). The efficacy of doxycycline prophylaxis in STIs prevention has been demonstrated. This study aimed to examine the utilization of doxycycline prophylaxis among MSM in China, providing evidence to inform future policies and guidelines. Methods: Between June and July 2025, a cross-sectional survey was conducted in China, using a convenience …
Evaluation and optimization of municipal-level health impact assessment policies in China based on the PMC index model
Objective: This study aims to develop an integrated framework combining text mining with the Policy Modelling Consistency (PMC) index model to evaluate China's Health Impact Assessment (HIA) policies, thereby advancing the methodological and theoretical framework for policy evaluation in health governance. Methods: This study focuses on health impact assessment policies issued at the municipal level in China since 2019. Using the NVivo 11 plus te…
Exploring Chlamydia trachomatis screening in Shenzhen
Objectives This study evaluates the feasibility of a sample pooling strategy for Chlamydia trachomatis detection in pre-marital and pre-pregnancy screening in China, where pooled testing for CT remains limited despite its use in COVID-19 and HIV screening. Methods From January to May 2024, 8,142 urine samples were collected from participants in pre-marital and pre-pregnancy health checks in Nanshan District. Positive urine samples with different …
Psychotic symptoms in Chinese patients with somatic symptom disorder
Psychotic symptoms are prevalent in individuals with various mental health disorders and frequently lead to adverse outcomes. In this study, we assessed the prevalence of psychotic symptoms and its associated conditions in a large sample of Chinese patients with somatic symptom disorder (SSD), which has not been examined systemically. We recruited 899 patients with SSD. We used the positive subscale of the Positive and Negative Syndrome Scale to …
Effect of dietary selenium intake on CVD
Objective: We aimed to examine the association between dietary S e intake and CVD risk in Chinese adults. Design: This prospective cohort study included adults above 20 years old in the China Health and Nutrition Survey (CHNS), and they were followed up from 1997 to 2015 ( n 16 030). Dietary data were retrieved from CHNS, and a 3-d, 24-h recall of food intake was used to assess the cumulative average intake of dietary S e, which was divided into …
Prevalence and Correlates of Cardiovascular Calcification and Its Prognostic Effects Among Patients With Chronic Kidney Disease
Background and Aims: The purpose of this study was to identify the characteristics and risk factors for cardiovascular calcification, and its relationship to prognosis, in patients with chronic kidney disease (CKD) stages 1–4. Methods: Cardiovascular calcification was evaluated at baseline by lateral abdominal radiography to detect abdominal aortic calcifications (AAC), and by echocardiogram to detect cardiac valvular calcifications (CVC), respec…
Simulation Studies Provide Evidence of Aerosol Transmission of Sars-CoV-2 in a Multi-Story Building via Air Supply, Exhaust and Sanitary Pipelines
A cross-layer non-vertical transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurred in a quarantine hotel in Guangzhou, Guangdong Province, China in June 2021. To explore the cross-layer transmission path and influencing factors of viral aerosol, we set up different scenarios to carry out simulation experiments. The results showed that the air in the polluted room can enter the corridor by opening the door to take foo…

Development and utility of a close contact information management system for the Covid-19 pandemic
This system provides a new way to manage close contacts and restrict the spread of COVID-19 by combining information technology with disease prevention and control strategies in the realm of public health. We hope that this system will serve as an example and guide for those anticipating similar work in other countries in response to current and future public health incidents
The evidence of indirect transmission of Sars-CoV-2 reported in Guangzhou, China
Contaminants with virus from confirmed patients can pollute the environment of public places, and the virus can survive on the surface of objects for a short period of time. Therefore, in addition to the conventional droplet transmission, there is also indirect contact transmission such as snot-oral transmission that plays a crucial role in community spread of the virus
Associations of Residential Greenness with Diabetes Mellitus in Chinese Uyghur Adults
Greenness exposure is nominated as a potential beneficial factor for health, but evidence is limited on its diabetes effects. We conducted a cross-sectional study between May and September 2016 in rural areas of northwestern China, including 4670 Uyghur adults, to explore the associations between residential greenness and fasting glucose levels and diabetes prevalence. Fasting glucose levels were determined, and information on covariates was coll…
Nutrition-Related Knowledge, Attitudes, and Practices (KAP) among Kindergarten Teachers in Chongqing, China
Kindergarten teachers play an important role in providing kindergarten children with education on nutrition. However, few studies have been published on nutrition-related knowledge, attitudes, and practices (KAP) of Chinese kindergarten teachers. This study aimed to assess the nutrition-related knowledge, attitudes, and practices (KAP) of kindergarten teachers in Chongqing, China. Thus, a cross-sectional survey was conducted using a structured KA…
Risk factors for long‐term post‐traumatic stress disorder among medical rescue workers appointed to the 2008 Wenchuan earthquake response in China
This study aims to determine the risk factors for clinically‐significant post‐traumatic stress disorder (PTSD) among Chinese medical rescue workers one year after the response to the Wenchuan earthquake on 12 May 2008. A sample of 337 medical workers who performed response work within the first three months of the event completed an online questionnaire, which included information on demographics, social support, the management and organisation o…
An investigation of the Status quo of China's Contemporary Youth’s Affective Quality
摘要: 本研究在青少年情感素质理论和发展的情感分类思想指导下, 在理论构想与实践探索相结合的基础上, 编制了富有原创性的内含6个分问卷、可测查青少年2层次6大类29种情感发展状况的调查工具——《青少年情感素质问卷》, 并以此对我国3类地区9大城市及其郊县的117所学校的25485名青少年学生进行首次大规模情感素质测查。结果发现: 我国青少年情感素质整体上处于积极正向状态, 但亟待提高; 男女生情感素质主要存在结构性差异; 情感素质未随学段升高而提高, 反有下降趋势, 其中乐学感和自信感下降达显著水平; 情感素质与学习成绩的自我评价、父母受教育程度呈正相关; 师生关系良好、教师有情施教对青少年学生各方面情感素质发展具有重要而直接的促进作用
