Abstract
Background: Hypertension is a leading cause of disability-adjusted life years lost in the United States. Adiponectin is a cytokine secreted by adipocytes that increases insulin sensitivity, maintains vascular homeostasis, and is inversely associated with adiposity. We sought to determine the risk of incident hypertension by level of adiponectin at baseline. Methods: The REasons for Geographic and Racial Differences in Stroke (REGARDS) study enrolled 30,239 Black and White US adults in 2003-2006, with a second visit ~9 years later. Adiponectin was measured at the baseline visit among a random sample of 4,400 participants who attended the second visit. Modified Poisson regression estimated the relative risk (RR) for incident hypertension by each 1 SD higher of log-transformed adiponectin level adjusting for age, race, and sex in a minimally adjusted model. The fully adjusted model added Southern Diet pattern, dietary ratio of sodium to potassium, BMI, waist circumference, and systolic blood pressure. Restricted cubic splines visualized RR of hypertension by level of adiponectin, relative to the median. Results: After excluding those with prevalent hypertension (threshold 140/90 mm Hg or blood pressure medication use; n=2477) and missing adiponectin (n =129), 1,877 participants remained (mean age 62 years, 49% male, 36% Black, with lower adiponectin in Black participants p<0.001). Incident hypertension occurred in 46% (95% CI 43, 50%) of Black adults and 32% (29, 34%) of White adults. The RR for incident hypertension for each 1-SD higher log adiponectin was 0.91 (0.83, 1.00) in the demographic model and 0.99 (0.89, 1.10) in the fully adjusted model. Hypertension risk was similar across the continuum of adiponectin ( Figure ). Conclusions: In a cohort of Black and White US adults without hypertension, level of adiponectin did not associate with risk of incident hypertension 9 years later after adjusting for other hypertension risk factors.
