HDL-C, longitudinal change and risk of mortality in a Chinese cohort study.

Background And Aims: High-density lipoprotein cholesterol (HDL-C) concentration and variability are both important factors of cardiovascular disease (CVD) and mortality. We aimed to explore the associations of HDL-C and longitudinal change in HDL-C with risk of mortality.

Methods And Results: We recruited a total of 69,163 participants aged ≥40 years and had medical examination records of HDL-C during 2010-2014 from the Yinzhou District, Ningbo, China.

Effect of COVID-19 on hospital visits in Ningbo, China: an interrupted time-series analysis.

Objective: Unprecedented rigorous public health measures were implemented during the coronavirus disease 2019 (COVID-19) epidemic, but it is still unclear how the intervention influenced hospital visits for different types of diseases. We aimed to evaluate the impact of the intervention on hospital visits in Yinzhou District, Ningbo, Zhejiang province, China.

Methods: We conducted an interrupted time-series analysis from 1 January 2017 to 6 September 2020 based on the Yinzhou Health Information System in Ningbo, Zhejiang province.

Short-term associations between ambient fine particulate matter pollution and hospital visits for chronic obstructive pulmonary disease in Yinzhou District, China.

Ambient particulate matter is one of the main risk factors of chronic obstructive pulmonary disease (COPD) in developing countries. However, the studies were scant in China concerning the health effects of the fine particulate matter (PM; particulate matter ≤ 2.5 μm in diameter) on hospital visits for COPD.

[Iodine nutritional status of child islanders in relation with iodized salt intake].

Objective: To evaluate the iodine nutritional status and its relation to iodized salt intake in child islanders.

Methods: A comparing study was carried out in 4 townships selected by random sampling from Dinghai (iodized salt) and Daishan(non-iodized salt) of Zhoushan island and total 592 of children were included in the study. The Mann-Whitney test was used to compare the urinary iodine concentration and dietary iodine intake of two groups.
