title: Behavioral response to induced conflict in families with a hypertensive father.
abstract: To clarify the possible environmental mediation of familial aggregation of blood pressure (BP), we examined whether the behavior of family members differed between families with a hypertensive (n = 16) or a normotensive (n = 15) father. Three-member families consisting of a father, mother, and a boy or girl aged 8-13 years were videotaped as they interacted under standard conditions calling for disagreement or conflict. Their BPs were recorded before and after interactions. The videotaped material was reliably coded into behavioral categories by independent observers. The aggregate of all three members of families with hypertensive fathers, as well as normotensive mothers and the children in these families, showed significantly more negative nonverbal behavior than their counterparts in families with normotensive fathers.
