Prevalence and predictors of white-coat hypertension in a large database of ambulatory blood pressure monitoring

The objective of this study was to determine both the prevalence of white-coat effect and white-coat hypertension [WCH] and which selected clinical variables were predictors of WCH. A total of 2462 patients underwent ambulatory blood pressure monitoring either in borderline hypertension [group 1] or for assessment of antihypertensive treatment [group 2] or for hypotension [group 3]. In the overall population 33.0% of patients showed WCH, 32.8% in group 1 and 37.0% in group 2. In multivariate analysis, sex and grade of hypertension were independent predictors of WCH in groups 1 and 2

Risk factors for hypertension among the adult Moroccan population

This study used data from the Moroccan national survey in 2000 to identify the principle risk factors for hypertension in a representative sample of the population age 20+ years. The risk of hypertension increased steadily with age and was higher among rural residents [OR = 1.42] and those with diabetes [OR = 1.72]. The risk increased with increased body mass index, waist size and hypercholesterolaemia. The risk of hypertension decreased by 36% and 46% respectively for those who walked 30-60 min and > 60 min daily. Consumption of fish and fresh fruits 1+ times per week was associated with a lower risk. Among those with hypertension, only 21.9% were previously diagnosed and 8.8% were under medical treatment
