Abstract:
Background and Objectives:Nonalcoholic fatty liver disease (NAFLD) is an excessiveaccumulation of fat into the liver as a result of increased inflammation and insulin resistance.Although there can be common pathogenic mechanisms for NAFLD and hypertensionassociated with the development of cardiovascular diseases, little data are showing theassociation between NAFLD and hypertension in a large-scale cohort study. Thus, weevaluated the ability of the fatty liver index (FLI), a surrogate marker of NAFLD, to predict thedevelopment of hypertension in healthy individuals.
Methods:We included 334,280 healthy individuals without known comorbidities whounderwent the National Health check-ups in South Korea from 2009 to 2014. Theassociation between the FLI and hypertension was analyzed using multivariate Coxproportional-hazards models.
Results:During a median of 5.2 years' follow-up, 24,678 subjects (7.4%) had new-onsethypertension. We categorized total subjects into quartile groups according to FLI (range: Q1,0–4.9; Q2, 5.0–12.5; Q3, 12.6–31.0; and Q4, >31.0). The incidence of hypertension was higherin subjects with the highest FLI than in those with the lowest FLI (Q4, 9,968 [11.9%] vs. Q1,2,277 [2.7%]; p<0.001). There was a significant correlation between the highest FLI and anincreased risk of new-onset hypertension (adjusted hazard ratio between Q4 and Q1, 2.330;95% confidence interval, 2.218–2.448; p<0.001). FLI was significantly associated with anincreased risk of new-onset hypertension regardless of baseline characteristics.
Conclusions:Higher FLI was independently associated with increased risk of hypertension ina healthy Korean population.
