Abstract
Background Hypertension is one of the main risk factors
for developing cardiovascular disease. Hypertension is less
common in children than in adults. It applies to 1-12% of
the population of children under the age of 18 years and is
in most cases a secondary condition.
Material and methods Children from 29 primary schools in the city and county of Slupsk were included in the study. Body weight and height, blood pressure and cholesterol, triglycerides, HDL, LDL levels were measured. The study was conducted between 15 September and 30 November 2008. 658 children took part in the study - 321 boys (48.78%) and 337 girls (51.22%). The height of the body in the study group was in the range of 135-179 cm, weight - 23-85 kg, BMI - 12.3-33.7. SBP ranged from 80 to 150 mm Hg, DBP - from 40 to 98 mm Hg, the MAP - from 52 to 110 mm Hg. Average SBP was 113.83 mm Hg in boys and 109.15 mm Hg in girls. Average DBP was 62.78 mm Hg in boys, and 63.23 mm Hg in girls.
Results Children with a body mass index ≥ 85th percentile much more frequently show a tendency to elevated blood pressure (BP). In the group of children with BMI ≥ 85th percentile, SBP and DBP values ≥ 90th percentile were observed in 31.09% (19.98% - girls, 11.21 - boys) and 11.54% (5.93% - girls, 5.61% - boys) respectively. However, in the group with BMI < 85th percentile, SBP and DBP values ≥ 90th percentile were observed in 27.41% (12.47% - girls, 14.94% - boys) and 8.81% (4.45% - girls, 4.35% - boys) respectively.
Conclusions The correlation between increased values of BMI and elevated blood pressure (0.1 ≤ rXY < 0.3; 0.3 ≤ rXY <0.5) are more common in girls. There was no apparent effect of area of residence on BMI and BP values.
