Study of blood pressure in elementary school children at hill and seashore areas

Abstract

Background Measurement of blood pressure is the most impor- tant tool for early detection of hypertension. There is an assump- tion that salt consumption of the population living at the seashore is higher than that of those living on the hill area, and it would lead to higher blood pressure. Objective To find out whether there is any difference of blood pressure between school-age children (6-13 years) living on the hill area (Brastagi subdistrict) and those living at the seashore area (Pantai Cermin sub district), North Sumatra. Methods A cross sectional study was conducted in Brastagi and Pantai Cermin from September to October 1995. The subjects were taken by a simple random sampling method. The blood pressure was measured based on recommendation of The Second Task Force on Blood Pressure Control in Children 1987. Results The means systolic pressure in boys of 6 years of age as well as in girls of 6,8,12 and 13 years, and the means of diastolic pressure in girls of 6,7,8,11 years were higher in Pantai Cermin (p0.05). Conclusion In children, there was no significant difference be- tween the prevalence of hypertension on hill and seashore area
