Anemia and insomnia: a cross-sectional study and meta-analysis.

Background: Several recent genome-wide association studies suggested insomnia and anemia may share some common genetic components. We thus examined whether adults with anemia had higher odds of having insomnia relative to those without anemia in a cross-sectional study and a meta-analysis.

Methods: Included in this cross-sectional study were 12,614 Chinese adults who participated in an ongoing cohort, the Kailuan Study.

Changes in pulse pressure × heart rate, hs-CRP, and arterial stiffness progression in the Chinese general population: a cohort study involving 3978 employees of the Kailuan Company.

Background: Pulse wave velocity (PWV) is a marker of arterial stiffness, which represents sub-clinical atherosclerosis. Pulsatile stress and high-sensitivity C-reactive protein (hs-CRP) are associated with arteriosclerosis. However, there is no prospective data confirming whether changes in pulsatile stress and inflammatory markers affect the progression of arterial stiffness.

Associations of urinary epidermal growth factor and monocyte chemotactic protein-1 with kidney involvement in patients with diabetic kidney disease.

Background: In diabetic kidney disease (DKD), it is important to find biomarkers for predicting initiation and progression of the disease. Besides glomerular damage, kidney tubular injury and inflammation are also involved in the development of DKD. The current study investigated the associations of urinary epidermal growth factor (uEGF), monocyte chemotactic protein-1 (MCP-1) and the uEGF:MCP-1 ratio with kidney involvement in patients at early and advanced stages of DKD.

Correlation between Carotid Intima-Media Thickness and Early-Stage Chronic Kidney Disease: Results from Asymptomatic Polyvascular Abnormalities in Community Study.

Objective: Chronic kidney disease (CKD) might be a potential independent risk factor for increased carotid intima-media thickness (IMT). Our aim is to determine whether mild to moderate kidney dysfunction is associated with increased carotid IMT.

Methods: We employed 3629 subjects free from clinical cardiovascular diseases at the baseline visit of the Asymptomatic Polyvascular Abnormalities in Community Study.

[Impact of resting heart rate on new-onset diabetes in population without hypertension].

Objective: To investigate the impact of resting heart rate (RHR) on new-onset diabetes (NOD) in population without hypertension.

Methods: This prospective cohort study was performed in 2006 and 2007 and screened 101 510 participants. All subjects were employees of the Kailuan Group, a state-run coal mining company.

[Relationship between the level of waist circumference and the impaired fasting glucose of pre-diabetes].

Objective: To explore the relationship between the level of waist circumference (WC) and the impaired fasting glucose (IFG) in people working for the Kailuan Enterprise.

Methods: A total of 101 510 subjects from the employees of Kailuan Group who took part in the health examination between 2006 to 2007, with fasting plasma glucose (FPG) < 6.1 mmol/L, no history of diabetes, completed data on FPG and WC examination and without using hypoglycemic agents, were selected as the observation cohort.

[Impact of the waist circumference change on new onset of diabetes in the population with impaired fasting glucose].

Objective: To explore the impact of the waist circumference change on new onset diabetes (NOD) in the impaired fasting glucose (IFG) population.

Methods: A total of 12 657 subjects who took part in the health examination from 2006 to 2007 and from 2010 to 2011 from the employees of Kailuan Group and met the inclusion criteria were selected as the observation cohort.Of the 12 657 subjects, 10 697 were male, 1960 were female, with age of (49.

[Impact of ideal health behaviors and health factors on the detection rate of the carotid plaques].

Objective: To explore the impact of ideal health behaviors and health factors on the detection rate of the carotid plaques.

Methods: Subjects with previous stroke, TIA, myocardial infarction were excluded from the study. A total of 5852 employees (active and retired employers from Tangshan Kailuan company) aged 40 years and over were included through stratified random sampling.
