Abstract
Background
Systemic inflammation and nutritional status are recognized as key contributors to hypertension pathogenesis. The Advanced Lung Cancer Inflammation Index (ALI), combining body mass index, serum albumin, and neutrophil-to-lymphocyte ratio, reflects these processes. However, its association with hypertension in general populations remains unclear.
Methods
Using data from a public database of 43,886 adults, we investigated the relationship between ALI and hypertension prevalence. ALI was calculated as BMI × serum albumin/neutrophil-to-lymphocyte ratio. Hypertension was defined by blood pressure, self-reported diagnosis, or antihypertensive treatment. Logistic regression models, adjusted for demographic, behavioral, and clinical confounders, assessed associations, with nonlinear and age-stratified analyses.
Results
Elevated ALI was strongly associated with higher odds of hypertension (adjusted OR per 10-unit increase: 1.035; 95% CI, 1.028–1.042). Individuals in the top ALI tertile had a 33.7% increased risk of hypertension compared to those in the lowest tertile (OR: 1.337; 95% CI, 1.261–1.417). Nonlinear modeling revealed stronger associations below age-specific ALI cutoffs (67.45 for ≤60 years; 78.48 for >60 years), with weaker effects above these thresholds, especially among older adults.
Conclusions
ALI is a novel biomarker associated with hypertension risk, offering potential for early screening and personalized management. Longitudinal studies are needed to confirm causality and clarify mechanisms.
