Serum urate association with hypertension in young adults: analysis from the Coronary Artery Risk Development in Young Adults cohort.

ABSTRACT: OBJECTIVE:To determine if serum urate concentration is associated with development of hypertension in young adults. METHODS:Retrospective cohort analysis from 4752 participants with available serum urate and without hypertension at baseline from the Coronary Artery Risk Development in Young Adults (CARDIA) study; a mixed race (African-American and White) cohort established in 1985 with 20 years of follow-up data for this analysis. Associations between baseline serum urate concentration and incident hypertension (defined as a blood pressure greater or equal to 140/90 or being on antihypertensive drugs) were investigated in sex-stratified bivariate and multivariable Cox-proportional analyses. RESULTS:Mean age (SD) at baseline was 24.8 (3.6) years for men and 24.9 (3.7) years for women. Compared with the referent category, we found a greater hazard of developing hypertension starting at 345 µmol/l (5.8 mg/dl) of serum urate for men and 214 µmol/l (3.6 mg/dl) for women. There was a 25% increase in the hazard of developing hypertension in men (HR1.25 (95% CI 1.15 to 1.36)) per each mg/dl increase in serum urate but no significant increase in women (HR 1.06 (95%CI 0.97 to 1.16)). CONCLUSIONS:We found a significant independent association between higher serum urate concentrations and the subsequent hazard of incident hypertension, even at concentrations below the conventional hyperuricaemia threshold of 404 µmol/l (6.8 mg/dl).

Project description:<p>The Coronary Artery Risk Development in Young Adults (CARDIA) Study is a study examining the development and determinants of clinical and subclinical cardiovascular disease and its risk factors. It began in 1985 with a group of 5115 black and white men and women aged 18-30 years. The participants were selected so that there would be approximately the same number of people in subgroups of race, gender, education (high school or less and more than high school) and age (18-24 and 25-30) in each of 4 centers: Birmingham, AL; Chicago, IL; Minneapolis, MN; and Oakland, CA. These same participants were asked to participate in follow-up examinations during 1987-1988 (Year 2), 1990-1991 (Year 5), 1992-1993 (Year 7), 1995-1996 (Year 10), 2000-2001 (Year 15), and 2005-2006 (Year 20). A majority of the group has been examined at each of the follow-up examinations (90%, 86%, 81%, 79%, 74%, and 72%, respectively).</p> <p>While the specific aims of each examination have varied, data have been collected on a variety of factors believed to be related to heart disease. These include conditions with clear links to heart disease such as blood pressure, cholesterol and other lipids, and glucose. Data have also been collected on physical measurements such as weight and skinfold fat as well as lifestyle factors such as substance use (tobacco and alcohol), dietary and exercise patterns, behavioral and psychological variables, medical and family history, and other chemistries (e.g., insulin). In addition, subclinical atherosclerosis was measured via echocardiography during Years 5 and 10, computed tomography during Years 15 and 20, and carotid ultrasound during Year 20.</p> <p><b>NHLBI Candidate-gene Association Resource.</b> The NHLBI initiated the Candidate gene Association Resource (CARe) to create a shared genotype/phenotype resource for analyses of the association of genotypes with phenotypes relevant to the mission of the NHLBI. The resource comprises nine cohort studies funded by the NHLBI including: Atherosclerosis Risk in Communities (ARIC), Cardiovascular Health Study (CHS), Cleveland Family Study (CFS), Coronary Artery Risk Development in Young Adults (CARDIA), Framingham Heart Study (FHS), Jackson Heart Study (JHS), Multi-Ethnic Study of Atherosclerosis (MESA), and the Sleep Heart Health Study (SHHS). A database of genotype and phenotype data was created that includes records for approximately 41,000 study participants with approximately 50,000 SNPs from more than 2,000 selected candidate genes. In addition, a genome wide association study using a 1,000K SNP Chip was conducted on approximately 8,900 African American participants drawn from five CARe cohorts: ARIC, CARDIA, CFS, JHS, and MESA. Data from individual cohorts is available to approved investigators through dbGaP.</p> <p><b>Some relevant CARe publications</b><br/> CARe Study: PMID <a href="http://www.ncbi.nlm.nih.gov/pubmed/20400780" target="_blank">20400780</a><br/> CVD Chip Design: PMID <a href="http://www.ncbi.nlm.nih.gov/pubmed/18974833" target="_blank">18974833</a> </p>
