Combined effect of hyperuricemia and overweight/obesity on the prevalence of hypertension among US adults: result from the National Health and Nutrition Examination Survey

摘要

Hypertension is a large and growing public health problem worldwide. Hyperuricemia and overweight/obesity are two of the most important risk factors for hypertension. However, their combined effect on the risk of hypertension is not known. Participants aged 20 years and older from the National Health and Nutrition Examination Survey from 1999-2012 were used to evaluate the separate and combined effects of hyperuricemia and overweight/obesity on the risk of prevalent hypertension among different race, gender and age groups. Participants (31 473) were used to estimate separate and combined effects on the prevalence of hypertension. The overall prevalence of hypertension among adults with a combination of hyperuricemia and overweight/obesity (50.2%, 95% confidence interval (Cl) 48.3-52.1%) was significantly higher than separate hyperuricemia (41.7%, 95% Cl 37.2-46.2%) and overweight/obesity (30.6%, 95% Cl 29.5-31.8%). The magnitude of odds ratio (OR) from the combination of hyperuricemia and overweight/obesity (OR = 4.53, 95% Cl 4.05-5.07) was significantly higher than both hyperuricemia (OR = 2.62, 95% Cl 2.07-3.32) and overweight/obesity (OR = 2.08, 95% Cl 1.89-2.30). Combined effect of hyperuricemia and overweight/obesity on the risk of hypertension is much stronger than any separate one. These data can provide important information for identification of target populations for future intervention and patient management.
