To investigate the association between alpha-Adducin (ADD1) methylation and blood pressure in young adults with essential hypertension.
Design and method:
A total of 160 subjects (80 normotensive and 80 incident hypertensive) aged between 18 to 45 years from Kuantan, Pahang were included in a cross-sectional study by purposive sampling. They were assessed for ADD1 methylation in peripheral blood using MethyLight assay. Anthropometric measurements and biochemical parameters were also examined.
ADD1 methylation was inversely correlated with systolic (p = 0.006, r = –0.240), diastolic (p = 0.001, r = –0.281) and mean arterial pressures (p = 0.002, r = –0.270). Hypertensive subjects had significantly higher ADD1 methylation than normotensive control (p = 0.005). After adjusting for other relevant covariates (age, body mass index, HbA1c, high-sensitivity C-reactive protein and low density lipoprotein cholesterol), ADD1 methylation remained a significant predictor for hypertension in young adults (p = 0.020)
ADD1 methylation is a significant predictor of hypertension in young adults. ADD1 methylation could serve as a future preventive and therapeutic target for hypertension and related cardiovascular disease.
