Patterns and Correlates of Bone Mineral Density Parameters Measured Using Calcaneus Quantitative Ultrasound in Chinese Adults.

Monitoring bone mineral density (BMD) in adults is critical for early detection of osteoporosis and prevention of fracture, for which quantitative ultrasound (QUS) is a good non-invasive tool. We examined the associations of QUS measures, including stiffness index (SI) and T-score, with socio-demographic, lifestyle, and anthropometric correlates and risk of subsequent fracture. : Calcaneal QUS was performed using GE's Lunar Achilles EXPII among 24,651 adults (mean age 59.

Acute Impact of Nonoptimal Ambient Temperatures on Plasma Levels of 3000 Proteins in Chinese Adults.

Polygenic risk scores for pan-cancer risk prediction in the Chinese population: A population-based cohort study based on the China Kadoorie Biobank.

Background: Polygenic risk scores (PRSs) have been extensively developed for cancer risk prediction in European populations, but their effectiveness in the Chinese population remains uncertain.

Methods And Findings: We constructed 80 PRSs for the 13 most common cancers using seven schemes and evaluated these PRSs in 100,219 participants from the China Kadoorie Biobank (CKB). The optimal PRSs with the highest discriminatory ability were used to define genetic risk, and their site-specific and cross-cancer associations were assessed.

Comparative studies of 2168 plasma proteins measured by two affinity-based platforms in 4000 Chinese adults.

Proteomics offers unique insights into human biology and drug development, but few studies have directly compared the utility of different proteomics platforms. We measured plasma levels of 2168 proteins in 3976 Chinese adults using both Olink Explore and SomaScan platforms. The correlation of protein levels between platforms was modest (median rho = 0.

Periodontitis-related myocardial fibrosis by expansion of collagen-producing SiglecF+ neutrophils.

Backgrounds And Aims: Patients with periodontitis (PD) are prone to developing myocardial infarction (MI), yet the prognosis and mechanisms remain unclear. Given the presumed close association of neutrophils with both conditions, this study aims to elucidate the roles of neutrophils in mediating the interaction between PD and MI.

Methods: Three prospective cohorts and PD + MI mouse model were investigated to assess the effects of PD on MI prognosis.

Associations of total, domain-specific, and intensity-specific physical activity with all-cause and cause-specific mortality in China: A population-based cohort study.

Background: Evidence of an association between physical activity (PA) and mortality has mainly focused on leisure-time physical activity (LTPA) and moderate-to-vigorous-intensity physical activity (MVPA). We aimed to assess the associations of total, domain-specific, and intensity-specific PA with all-cause and cause-specific mortality.

Methods: We used baseline PA data from the China Kadoorie Biobank, including 482,067 participants aged 30-79 years from 10 areas in China.

Physical Activity and Ischemic Heart Disease Risk: A Prospective Cohort Study Among Chinese Adults.

Background: Type-specific physical activity (PA) may be associated with different risks of ischemic heart disease (IHD), but few large studies have examined this. This study aimed to assess the incidence and dose-response relationships between total PA and 4 different types of PA and IHD risk in Chinese adults.

Methods: The prospective China Kadoorie Biobank enrolled 35,508 adults from Qingdao from 2004 to 2008, including 33,342 IHD-free participants in this analysis.

Long-Term Fine Particulate Matter Exposure on Lung Cancer Incidence and Mortality in Chinese Nonsmokers.

The association between fine particulate matter (PM) and lung cancer incidence in non-smokers (LCINS) remains inconsistent. To investigate the association between long-term PM exposure and LCINS in a Chinese population and to assess the modifying effect of genetic factors. Time-dependent Cox proportional hazard models were employed to evaluate the hazard ratios (HR) and 95% confidence interval (CI) of PM with LCINS risk and LCINS-related mortality.

Associations Between Snoring, Body Mass Index and Coronary Artery Diseases: Observational and Mendelian Randomization Study in Asia.

Background And Objective: Previous observational studies reported a complex relationship between snoring and coronary artery disease (CAD). We aimed to estimate the causal associations between snoring and CAD among East Asian people, and the effects independent of BMI.

Methods: Based on 497,250 adults from China Kadoorie Biobank (CKB), we performed a conventional prospective analysis between snoring and CAD outcomes, using the multivariable Cox regression.

Adiposity and risks of gastrointestinal cancers: A 10-year prospective study of 0.5 million Chinese adults.

Associations of adiposity with risks of oesophageal squamous cell carcinoma (ESCC) and non-cardia stomach cancer, both prevalent in China, are still inconclusive. While adiposity is an established risk factor for colorectal cancer, the relevance of fat-free mass and early-adulthood adiposity remains to be explored. The prospective China Kadoorie Biobank study included 0.

Comparison of models to predict incident chronic liver disease: a systematic review and external validation in Chinese adults.

Background: Risk prediction models can identify individuals at high risk of chronic liver disease (CLD), but there is limited evidence on the performance of various models in diverse populations. We aimed to systematically review CLD prediction models, meta-analyze their performance, and externally validate them in 0.5 million Chinese adults in the China Kadoorie Biobank (CKB).

Phenotypic Versus Genetic Mismatch of BMI and Type 2 Diabetes: Evidence From Two Prospective Cohort Studies.

Unlabelled: Little is known about the population-based mismatch between phenotypic and genetic BMI (BMI-PGM) and its association with type 2 diabetes. We therefore used data from the China Kadoorie Biobank and UK Biobank and calculated BMI-PGM for each participant as the difference between the percentile for adjusted BMI at baseline and the percentile for adjusted polygenic risk score for BMI. Participants were categorized into discordantly low (BMI-PGM < the first quartile), concordant (the first quartile ≤ BMI-PGM < the third quartile), and discordantly high (BMI-PGM ≥ the third quartile) groups.

Associations of long-term nitrogen dioxide exposure with a wide spectrum of diseases: a prospective cohort study of 0·5 million Chinese adults.

Background: Little evidence is available on the long-term health effects of nitrogen dioxide (NO) in low-income and middle-income populations. We investigated the associations of long-term NO exposure with the incidence of a wide spectrum of disease outcomes, based on data from the China Kadoorie Biobank.

Methods: This prospective cohort study involved 512 724 Chinese adults aged 30-79 years recruited from ten areas of China during 2004-08.

Risk prediction of ischemic heart disease using plasma proteomics, conventional risk factors and polygenic scores in Chinese and European adults.

Plasma proteomics could enhance risk prediction for multiple diseases beyond conventional risk factors or polygenic scores (PS). To assess utility of proteomics for risk prediction of ischemic heart disease (IHD) compared with conventional risk factors and PS in Chinese and European populations. A nested case-cohort study measured plasma levels of 2923 proteins using Olink Explore panel in ~ 4000 Chinese adults (1976 incident IHD cases and 2001 sub-cohort controls).

Trends of genetic contributions on epigenetic clocks and related methylation sites with aging: A population-based adult twin study.

Several crucial acceleration periods exist during aging process. Epigenetic clocks, serving as indicators of aging, are influenced by genetic factors. Investigating how the genetic contributions on these clocks change with age may provide novel insights into the aging process.
