The prevalence of hypertension in gynaecoid and android obese women.

Until now the different epidemiological studies performed have yielded widely different results in terms of the prevalence of hypertension in obese patients. This is mainly due to methodological errors in blood pressure (BP) measurements, including such false positives as white-coat or cuff hypertension, and more recently, to the different distribution in the study population of obese subjects at risk of hypertension (android obesity type). In 803 obese outpatient women (body mass index range: 28-45) randomly selected and subdivided into younger and older groups, and into android and gynaecoid, the casual BP was measured in the morning with a large size cuff. In addition, in 82 obese outpatients casual BP was measured simultaneously with the large and a standard size cuff. Another group of 94 patients was submitted to 24-h ambulatory blood pressure monitoring (ABPM). The aim was to observed if the use of inappropriate cuffs, or the incidence of white-coat hypertension and the prevalence of obese subjects at risk of hypertension, may contribute considerably to overestimating the prevalence of hypertension in obesity. The hypertension prevalence rate was 37.6% for the entire study group. The prevalence rate was 26.2% in women with gynaecoid type of obesity and 47.1% in android obese subjects. We could conclude that the use of inappropriate cuffs, office or white-coat hypertension and the prevalence of obese subjects at risk of hypertension, may contribute considerably to overestimating the prevalence of hypertension in obesity. The number of hypertensive subjects in younger obese subjects with gynaecoid fat distribution is similar to non-obese subjects who are age-adjusted, but our data confirm that the prevalence of hypertension in android type of obesity is significantly higher than in non-obese subjects.
