Abstract
Background An important link between arterial hypertension and body mass is well established, however not fully recognized not only by patients, but sometimes by their physicians. The aim of our study was to evaluate an effectiveness of action on prevention SPES (Southern Polish Epidemiological Survey) among persons with a high risk for coronary artery disease in relation to body mass.
Methods An examined population consisted of 992 randomly selected subjects from 7965 participants of action on prevention SPES, who had carried an increased risk for coronary heart disease. There were 771 men (77,7%) aged 64 ± 7 year (range 38–86) and 221 women (22,3%) aged 66 ± 7 years (range 42–82). Blood pressure measurements and body mass index (BMI) were analyzed. Blood pressure changes between initial and subsequent measurements were evaluated in three groups according to BMI values: < 25, 25–29,9 and = 30 kg/m2.
Results The prevalence of overweight and obesity was 80,8% initially and 75,4% 3 years later. The proportion of subjects with blood pressure measurements indicating hypertension rose along with BMI increase at first examination being: 84,2% in subjects with BMI < 25, 87,3% with BMI 25–29,9 and 94,3% with BMI = 30. Similar trend was observed after 3 years: 67,6%, 79,4% and 88,5%, respectively. Importantly, in subjects with normal BMI the percentage of BP measurements within optimal values was the greatest. However, isolated systolic hypertension almost doubled during this period, irrespective on initial BMI.
