Association between exposure to metalworking fluid aerosols, occupational noise and chronic kidney disease: a cross-sectional study in China.

Background: Chronic kidney disease (CKD) carries a high public health burden yet little is known about the relationship between metalworking fluid (MWF) aerosols, occupational noise and CKD. We aimed to explore the relationship between occupational MWF aerosols, occupational noise and CKD.

Methods: A total of 2,738 machinists were sampled from three machining companies in Wuxi, China, in 2022.

Association between occupational noise and obesity: a retrospective cohort study in China.

Objectives: To determine the relationship between occupational noise, and obesity and body mass index (BMI) changes.

Methods: Baseline data were collected from participants (n = 1264) who were followed for 6 years in a retrospective study. The noise exposure level (L) was determined by equivalent continuous weighted sound pressure levels using the fixed-point surveillance method for noise monitoring.

Relationship between exposure to metalworking fluids and nonalcoholic fatty liver disease.

Objective: The relationship between metalworking fluids (MWFs) and nonalcoholic fatty liver disease (NAFLD) has not been previously explored. We aim to investigate the relationship between occupational exposure to MWFs and the prevalence of NAFLD and to determine the cumulative exposure threshold per day.

Methods: In 2020, 2079 employees were selected randomly from one computer numerical control machining factory in Wuxi for a questionnaire survey, and occupational health examinations were conducted at the affiliated branch of Wuxi Eighth People's Hospital.

A cohort study on the association between changing occupational stress, hair cortisol concentration, and hypertension.

Objective: To explore the relationship between changing occupational stress levels, hair cortisol concentration (HCC), and hypertension.

Methods: Baseline blood pressure of 2520 workers was measured in 2015. The Occupational Stress Inventory-Revised Edition (OSI-R) was used to assess changes in occupational stress.

Shift patterns, physical exercise, and Type 2 diabetes mellitus (T2DM): a prospective cohort study in China.

To examine the relationships between different shift patterns and Type 2 diabetes mellitus (T2DM) risk, and determine whether physical exercise reduced the incidence of T2DM in shift workers in the oil industry. Baseline data were collected from participants in May 2013 who were then followed for 4 years in a prospective cohort study. The cohort initially consisted of 3,002 workers and ultimately included 2,827 people.

The relationships of shift work, hair cortisol concentration and dyslipidaemia: a cohort study in China.

Background: Currently, cardiovascular disease is the leading cause of death, and dyslipidaemia is an independent and modifiable major risk factor. Previous studies on shift work with dyslipidaemia and hair cortisol concentration (HCC) have yielded conflicting results. The aim of this study was to clarify the association between shift work, dyslipidaemia, and HCC.

Relationships among N,N-dimethylformamide exposure, CYP2E1 and TM6SF2 genes, and non-alcoholic fatty liver disease.

Objective: This study aimed to examine the relationships among N, N-dimethylformamide (DMF) exposure, cytochrome P4502E1 (CYP2E1) single nucleotide polymorphisms (SNPs) (rs2031920, rs3813867, rs6413432), transmembrane 6 superfamily member 2 (TM6SF2) SNP rs58542926 and non-alcoholic fatty liver disease (NAFLD).

Methods: Baseline data were collected from participants who were then followed for 5 years in a prospective cohort study. The cohort initially consisted of 802 workers and ultimately included 660 people, all of whom underwent annual occupational health examinations from 2010 to 2015.
