Prevalence of arterial hypertension at two follow-up measurements of blood pressure in family members with and without relative killed during the war in Bosnia and Herzegovina*

	No. of family members with arterial hypertension/total No. of subjects (%)†
Family member	1996	2003
With a killed relative	630/1144 (55.1)	543/1070 (50.7)
Without a killed relative	245/582 (42.1)	212/544 (39.0)
Group difference (%, 95% CI)‡	13.0 (8.0-17.8)	11.8 (6.7-16.8)

*The study involved 1726 closest relatives (parents, grandparents, siblings, or spouses) of the solders who fought in the war in Bosnia and Herzegovina during 1992-1995. Follow-up lasted from 1996 to 2003.

†Arterial hypertension was defined as systolic blood pressure ≥140 mm Hg (≥130 mm Hg in patients with diabetes mellitus), or diastolic blood pressure ≥90 mm Hg (≥80 mm Hg in patients with diabetes mellitus), or taking antihypertensive therapy (4).

‡Fisher exact test, P<.001 for both 1996 and 2003; CI – confidence interval.
