How to strengthen primary health care? An exploratory study on the policy of vertical integration of high-quality medical resources based on symbiosis theory
Background: The Vertical Integration of High-Quality Medical Resources (VI-HQMR) is a strategy of medical resource reallocation. It is the key to strengthen primary health care (PHC) and build an integrated delivery system (IDS). It contributes to the Sustainable Development Goals (SDGs) of universal health coverage (UHC) set out by the World Health Organization (WHO). In order to VI-HQMR, countries around the world have carried out many benefici…
Body mass index and sleep duration may regulate the effect of heavy metals on age at menopause
Heavy metals are known endocrine disruptors that can interfere with ovarian function, but there are few epidemiological studies studying the impact of heavy metals on menopause. In this cross-sectional survey, we recruited 414 naturally postmenopausal women in the early postmenopausal stage (12 months ≤ time since last menstruation ≤ 24 months). We collected information on women's menopausal age through questionnaires. Blood concentrations of fiv…
Association of Metals and Metalloids With Urinary Albumin/Creatinine Ratio
Background: Environmental exposure to toxic elements contributes to the pathogenesis of chronic kidney disease (CKD). Few studies focus on the association of urinary metals and metalloids concentrations with the urinary albumin/creatinine ratio (UACR) among elderly, especially in areas and seasons with severe air pollution. Objective: We aimed to evaluate the associations of urinary metals and metalloids concentration with UACR, which is an early…
Residential greenness attenuated association of long-term air pollution exposure with elevated blood pressure
Background Evidence on the hypertensive effects of long-term air pollutants exposure are mixed, and the joint hypertensive effects of air pollutants are also unclear. Sparse evidence exists regarding the modifying role of residential greenness in such effects. Methods A cross-sectional study was conducted in typically air-polluted areas in northern China. Particulate matter with diameter < 1 μm (PM 1 ), particulate matter with diameter < 2.5 μm (…
A Two-Stage Method to Estimate the Contribution of Road Traffic to PM2.5 Concentrations in Beijing, China
Traffic emissions account for a substantial share of daily total PM2.5 concentrations in Beijing. Our two-stage method is a useful and convenient tool in ecological and epidemiological studies to estimate the traffic contribution to PM2.5 concentrations when there is limited information on vehicle number and types and emission profile
Ambient Fine Particulate Matter Exposure and Risk of Cardiovascular Mortality
Few studies have explicitly explored the impacts of the extensive adjustment (with a lag period of more than one week) of temperature and humidity on the association between ambient fine particulate matter (PM 2.5 ) and cardiovascular mortality. In a time stratified case-crossover study, we used a distributed lag nonlinear model to assess the impacts of extensive adjustments of temperature and humidity for longer lag periods (for 7, 14, 21, 28 an…
