Abstract
We studied the prevalence of hypertension in 57,499 male and 35,803 female Israeli military recruits and its relation with sex, weight, and parents' ethnic origin. The overall prevalence of systolic hypertension (greater than 140 mmHg) was 1.75 per cent for males and 0.32 per cent for females. The prevalence of diastolic hypertension (greater than 90 mmHg) was 0.41 per cent for males and 0.06 per cent for females. For males, the prevalence of systolic and diastolic hypertension increased with weight, exponentially. Males of Ashkenazi origin had a significantly higher prevalence of hypertension (systolic 2.52 per cent, diastolic 0.55 per cent) compared with those of Sephardi origin (systolic 1.12 per cent, diastolic 0.3 per cent). The prevalence of adolescents with systolic or diastolic blood pressure greater than the mean +2SD of each weight group ranged between 1.5-2.3 per cent.
