FKBP5 is a critical gene involved in regulating the hypothalamic-pituitary-adrenal (HPA) axis and stress response. Aberrant DNA methylation at FKBP5 cytosine-phosphate-guanine (CpG) sites, such as cg22363520 and cg00862770, has been implicated in mental health disorders and metabolic diseases, including Type 2 diabetes. Exercise is a modulator of DNA methylation and metabolic health.

Obesity and smoking are two major public health challenges that both significantly contribute to morbidity and mortality worldwide. This study investigated the associations between smoking behaviors and obesity among men in Taiwan, with a focus on body mass index (BMI) and waist circumference (WC) as indicators of general and abdominal obesity. The sample consisted of 27,908 men categorized into five groups based on their specific smoking statuses: never smoker (NS), former smoker (FS), light-intensity smoker (LIS), moderate-intensity smoker (MIS), and heavy-intensity smoker (HIS).

Article Synopsis
  • The study investigates the relationship between alcohol consumption, a specific genetic variant (rs199347), and DNA methylation levels related to the glycoprotein GPNMB, which is linked to Parkinson's disease (PD).
  • Genetic and DNA methylation data were analyzed from 1,357 participants in the Taiwan Biobank, focusing on the interactions between the genetic variant and alcohol consumption in relation to methylation levels.
  • Findings indicate that alcohol consumption in individuals with the rs199347 GG genotype was associated with lower methylation of cg17274742, potentially increasing the expression of the GPNMB gene and posing a higher risk for PD.

Objective: To develop and validate machine learning models for predicting coronary artery disease (CAD) within a Taiwanese cohort, with an emphasis on identifying significant predictors and comparing the performance of various models.

Methods: This study involved a comprehensive analysis of clinical, demographic, and laboratory data from 8,495 subjects in Taiwan Biobank (TWB) after propensity score matching to address potential confounding factors. Key variables included age, gender, lipid profiles (T-CHO, HDL_C, LDL_C, TG), smoking and alcohol consumption habits, and renal and liver function markers.

Osteoporosis is a prevalent condition marked by reduced bone density and an elevated risk of fractures, especially among postmenopausal women. Exercise plays a crucial role in preventing and managing osteoporosis, with weight-bearing and impact exercises being particularly effective in enhancing bone density and mitigating disease risk. This study investigated the relationship between various types of impact exercises and osteoporosis using data from the Taiwan Biobank (TWB).

Ingested arsenic is carcinogenic to the human urinary tract, but uncertainties remain regarding the dose-response relationship. To assess dose-response relationships between arsenic ingestion and urinary cancers, we evaluated the associations between the arsenic level in drinking water and mortality of cancers of the bladder, kidney, and prostate in Taiwan. We utilized the 1971-2000 Taiwan death registry data and calculated the age-standardized mortality rates (ASMRs) using the 1976 world standard population as the reference group.

Purpose: This study investigates the influence of demographic changes on the effectiveness of hospital nurse staffing policy, measured by the cumulative response of inpatient care quality to adjustments in hospital nurse staffing levels in Taiwan.

Methods: The research design utilized in this study aligns with the observational time-series methodology, and a total of 99 monthly time-series observations were collected from multiple databases administered by the Taiwan government over the period from January 2015 to March 2023. Specifically, the time-varying parameter vector autoregressive and autoregressive distributed lag models were employed to investigate the association between age distribution and nurse staffing policy effectiveness.

Article Synopsis
  • G6PD deficiency may heighten the risk of developing type 2 diabetes mellitus (T2DM), with variations in prevalence between males and females, yet its sex-specific effects in the Taiwanese population are not well-studied.
  • This research analyzed data from 85,334 participants (ages 30-70) to evaluate the relationship between G6PD deficiency (specifically the rs72554664 variant) and T2DM risk, using logistic regression methods.
  • Results showed that the TC + TT genotype of rs72554664 significantly increased T2DM risk, especially in males, who had an odds ratio of 4.57 for the hemizygous T allele compared to females, highlighting the importance of considering

Article Synopsis
  • The study aimed to identify new significant SNPs related to osteoporosis using data from the Taiwan Biobank.
  • Analysis involved dividing data into discovery and replication subsets, performing GWAS, and utilizing the FUMA platform for visualizations and mapping of SNPs to genes.
  • A new independent significant SNP, rs76140829, was discovered with strong associations, and six genes were identified through chromatin interaction mapping.

  • A study explored the relationship between coffee consumption, the rs301 variant of the LPL gene, and metabolic syndrome (MetS) among 9,523 Taiwanese individuals.
  • Results showed that coffee drinkers had a lower likelihood of MetS, with specific genetic variants ('TC' and 'CC') further reducing this risk compared to the 'TT' genotype.
  • The interaction between coffee consumption and the rs301 variant revealed notable protections against MetS, especially highlighting that non-coffee drinkers did not show signs of MetS regardless of their genotype.

Recent studies showed significant associations between socio-demographic, lifestyle factors, polymorphic variant rs6265, and smoking cessation behaviours. We examined rs6265 TT, TC and CC genotypes and their association with socio-demographic and other variables, including mental health status, drinking, exercise, and smoking behaviour among Taiwanese adults. Data on rs6265 were retrieved from the Taiwan Biobank, which contained genetic data collected between 2008 to 2019 from 20,584 participants (aged 30-70 years).

Unlabelled: We determined the association of vegetarian type and status with bone mineral density (BMD) Z-scores at the spine, hip, and femoral neck. Compared to non-vegetarians, current vegetarians, especially vegans, lacto-vegetarians, and lacto-ovo-vegetarians had lower Z-scores at multiple sites. Sole reliance on a vegetarian diet might be detrimental to the bone.

Background: Parkinson's disease (PD) is a complex neurodegenerative disease with an elusive etiology that involves the interaction between genetic, behavioral, and environmental factors. Recently, epigenetic modifications, particularly DNA methylation, have been recognized to play an important role in the onset of PD. Glycoprotein non-metastatic melanoma protein B (GPNMB), a type I transmembrane protein crucial for immune cell activation and maturation, has emerged as a potential biomarker for the risk of PD.
