Abstract
Background and Objectives: Few population-based data on the prevalences of masked and white-coat hypertension exist. We collected 24-hour ambulatory blood pressure (BP) and urine in a random subset of participants to the population-based CoLaus study.
Methods: Clinic BP was measured using an Omron HEM 907 device and ambulatory BP (ABP) using a Diasys Integra device. Masked hypertension (MH) was defined as clinic BP < 140/90mm Hg and 24-hour ABP >¼135/85mmHg. White coat hypertension (WCH) was defined as clinic BP >¼ 140/90mm Hg and ABP <135/85mm Hg. Microalbuminuria was defined as present if urinary albumin excretion was > 20mg/min.
Results: The 198 men and 213 women were aged (mean_SD) 56.2_10.7 and 57.2_10.3 years and had mean urinary excretion of 148_65 and 122_52 mmol/24 h for sodium and 70_24 and 5721 mmol/24 h for potassium, respectively. In men and women, the prevalences were 34.9% and 31.0% for clinic hypertension, 42.9% and 32.9% for ambulatory hypertension, 12.6% and 5.6% for MH, and 4.5% and 3.8% for WCH, respectively. The higher prevalence of MH in men was explained, in part, by higher alcohol consumption and smoking. Participants with MH tended to have higher microalbuminuria (13.5% vs 5.8%, P¼0.067). Participants with WCH had no microalbuminuria.
Conclusions: In the Lausanne population aged 38 to 78 years, the prevalence of hypertension based on ABP was high, despite moderate dietary salt intake. Men had higher prevalence of MH then women. The prevalence of WCH was low and similar in men and women. MH tended to be associated with early kidney damage.
