Article Abstract
Context: The relationship between methylenetetrahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) gene polymorphisms and H-type hypertension susceptibility has been deeply analysed, but the conclusions are not consistent. Therefore, we carried out a meta-analysis aimed at assessing the relationship exactly.
Methods: Six English databases (PubMed, Embase, EBSCO, ScienceDirect, Cochrane Library, and Web of Science) and four Chinese databases (China Biological Medicine, WanFang, China Science and Technology Journal, and China National Knowledge Infrastructure) were used for searching studies from inception to August 2023. MTHFR C677T/A1298C and MTRR A66G genetic polymorphisms were evaluated.
Results: A total of 24 papers were included in our research, including 3649 H-type hyperpietics, 2772 non-H-type hyperpietics, and 2149 healthy controls. Our analysis shows that MTHFR C677T polymorphism showed significant association with H-type hypertension in both healthy individuals and non-H-type hyperpietics (TT vs. CC: OR = 3.43, 95% CI = 2.48-4.75). Further subgroup analysis based on geography revealed that homocysteine levels in the southern Chinese population were more susceptible to MTHFR C677T polymorphism ( < 0.05). However, there was no significant association in all genetic models for the polymorphisms of MTHFR A1298C and MTRR A66G.
Conclusion: MTHFR C677T polymorphisms are associated with H-type hypertension in non-H-type hyperpietics and healthy individuals.

Patterns and Correlates of Concurrent Serum Vitamin D, Folate, and Vitamin B Status in a Rural Chinese Population.
J Nutr
August 2025
Department of Epidemiology, School of Public Health, Southern Medical University, Guangzhou, Guangdong, China. Electronic address:
Background: Vitamin D, folate, and vitamin B are essential micronutrients with widespread insufficiencies globally. Although most previous research examined each of these nutrients individually, few studies have measured biomarkers of these nutrients concurrently in a large population.
Objectives: We aimed to investigate the patterns of concurrent insufficiencies or deficiencies of these nutrients based on serum biomarkers and influencing factors in a rural Chinese population.
Homocysteine, HHcy, H-type hypertension and dizziness: an NHANES analysis.
Front Neurol
July 2025
Department of Otorhinolaryngology, The First Affiliated Hospital of Xinjiang Medical University, Urumqi, China.
Background: Homocysteine (Hcy) is associated with various diseases, but its specific relationship with different types of dizziness remains unclear.
Objectives: This study utilizes NHANES cross-sectional data to investigate the associations between Hcy levels, H-type hypertension, and various symptomatic dizziness, aiming to provide new insights for clinical diagnosis and treatment.
Materials And Methods: This cross-sectional study analyzed 6,970 participants from NHANES (1999-2004) using weighted logistic regression, trend tests, restricted cubic spline analysis, and subgroup analysis.
Association between triglyceride-glucose index multiplied by waist circumference and H-type hypertension among Chinese adults.
Front Cardiovasc Med
July 2025
Clinical Epidemiology Research Office, The First Affiliated Hospital of Hunan Normal University, Changsha, China.
Backgrounds: The triglyceride-glucose index combined with waist circumference (TyG-WC) has good predictive performance for cardiovascular disease, but the relationship of TyG-WC with H-type hypertension (HTH) is still unclear.
Objects: To explore the association between TyG-WC and HTH, and provide theoretical basis for the prevention and treatment of HTH in the community population.
Methods: The study used multi-stage cluster random sampling to collect representative samples from urban and rural populations in Hunan Province.
CYP1A1/20-HETE/GPR75 Axis-Mediated Arachidonic Acid Metabolism Dysregulation in H-Type Hypertension Pathogenesis.

Beijing Municipal Key Laboratory of Child Development and Nutriomics, Capital Children's Medical Center, Capital Medical University, Capital Institute of Pediatrics, Beijing 100020, China.
This study aims to explore the pathogenic mechanism of H-type hypertension. A rat model of H-type hypertension was established through high-methionine dietary intervention, with subsequent folic acid administration. Untargeted serum metabolomic profiling identified a significant reduction in arachidonic acid (AA) levels in the methionine-enriched group, which were effectively normalized following folic acid supplementation.

Department of Chronic Non-Communicable Diseases Control and Prevention, Hangzhou, China.
Objective: Reports on urinary potassium excretion and H-type hypertension remains rare. We aimed to describe the relationship between 24-hour (h) urinary potassium excretion and the risk of H-type hypertension and non-H-type hypertension, thus to guide personal and public health campaigns including dietary recommendations to lower H-type hypertension and non-H-type hypertension in China.
Methods: In 2020 in Zhejiang, China, a cross-sectional survey on Salt Reduction and Prevention of Hypertension was conducted by using a stratified multistage random sampling strategy, with participants aged 21 to 72 years.
