Mental Health Literacy and Stigma Among Community Pharmacists in Jordan: A Cross-Sectional Study.

In China, occupational populations may be exposed to both workplace hazards and environmental pollutants, which may contribute to the substantial burden of non-communicable diseases (NCDs) and represent an important public health concern (). Coal miners are a particularly relevant occupational group because they may experience chronic exposure to coal dust, high temperatures, noise, hypoxia, and environmental pollution in mining areas, together with long employment duration, high work intensity, and psychological stress. Inadequate health management and safety education may further aggravate health risks in this population. Previous studies have linked coal-mining-related occupational and environmental exposures with sleep disorder, hypertension (), cardiovascular diseases (CVDs) (), chronic kidney disease (), dyslipidemia (), metabolic abnormality (), reproductive system disease (), anxiety, depression, and tumors (, ). Therefore, targeted occupational health management and safety education for coal miners are important for NCD prevention and control and likely to yield substantial health benefits. Current NCD management models focus predominantly on community settings, older adults, and legally defined occupational diseases, with comparatively less attention to NCDs in large occupational groups. Evidence from previous studies suggests that occupational personal protection is relevant to workers’ health. For example, studies have reported associations between dust exposure and chronic disease risk, supporting the need for improved occupational safety measures and personal protective equipment (PPE) (). Prior studies have also suggested that interventions addressing workplace and lifestyle factors may improve physical and mental health outcomes (). For example, a longitudinal study of workers with chronic diseases in the Netherlands from 2010 to 2016 reported that optimizing working patterns was associated with improved health-related employment outcomes (RR = 0.46) (). A three-week community-based dietary intervention among women in Canada reduced body weight (1.4%), total cholesterol (TC) (14.1%), low-density lipoprotein cholesterol (LDL-C) (16.8%), fasting plasma glucose (FPG) (6.3%), and C-reactive protein (CRP) (14.0%), accompanied by gut microbiome modulation and beneficial microbial metabolites (). A 12-month dietary intervention in 612 older adults from several European countries showed that a Mediterranean diet increased beneficial microflora such as and , while decreasing and , which are associated with frailty (). In addition, the gut microbiota plays a central role in host homeostasis and metabolic regulation, and probiotics may exert protective effects by preserving microbial balance (). Against this background, we established the Guangdong Pharmaceutical University Occupational Health Cohort in Xishan Coal Electricity Group (GDPU-OHC), an ambispective occupational cohort of coal mine workers in Shanxi Province, China. This cohort profile describes the cohort design, baseline characteristics, occupational exposure information, biospecimen collection, and planned follow-up framework. GDPU-OHC is intended to characterize the NCD burden in this occupational population, support future longitudinal analyses of occupational and lifestyle exposures, and provide a platform for planned nested sub-studies, including occupational protection improvement, work pattern optimization, dietary optimization, and gut microbiota modulation.
