Background: Hypertension, a major global health concern, is closely associated with obesity and lipid abnormalities. Remnant cholesterol (RC), a triglyceride-rich lipoprotein component, has been linked to cardiovascular diseases, but its joint impact with body mass index (BMI) on hypertension risk remains unclear.
Methods: We analyzed data from 3805 participants (mean age: 57 years; 44.3% male) in the China Health and Retirement Longitudinal Study (CHARLS) from 2011– 2020. Inclusion criteria were adults aged over 45 years with complete data on blood lipids and BMI. Participants with baseline hypertension or missing covariate data were excluded. Cox proportional hazard models assessed associations, while mediation analysis explored RC’s role in BMI-hypertension linkage.
Results: Over a 9-year follow-up, 590 participants developed hypertension. Obesity (BMI ≥ 28.0 kg/m²) and high RC levels were independently associated with hypertension (HR: 2.18; 95% CI: 1.48– 3.21 for the highest RC tertile). RC mediated 7.07% of BMI’s effect on hypertension, and BMI mediated 29.3% of RC’s effect.
Conclusion: This study highlights the intertwined roles of BMI and RC in hypertension development. Targeting both risk factors may enhance prevention strategies.
