The association of the Type A behavior pattern with change in blood pressure was examined in a multiethnic sample of schoolchildren.
Blood pressure was assessed in 1978 (mean age=8 years) and approximately biannually thereafter through 1987-1990, when a post-high school screening was completed.
The Matthews Youth Test for Health (MYTH) was completed by the teachers of a sample of participants in 1982 (n=502).
The Jenkins Activity Survey (JAS) was completed by all adolescents who participated in the post-high school screening (n=816).
Males were more likely to be classified as Type A than were females by the JAS and the MYTH.
Type A status was not associated cross-sectionally with elevated blood pressure.
JAS-assessed Type B males had significantly higher mean post-high school fourth-and fifth-phase diastolic blood pressures than did Type A males (70.2 mmHg vs. 68.2 mmHg, p<0.05 ; 68.1 mmHg vs. 65.2 mmHg, p<0.01).
JAS-assessed Type A/B status was not associated with 10-year change in blood pressure.
MYTH-determined Type B females tended to have higher diastolic blood pressures than MYTH-determined Type A females throughout the 10-year study period.
Results from this study did not confirm the hypothesis that Type A participants would have significantly higher blood pressures than Type B participants at the time of Type A assessment ; nor did they confirm the hypothesis that Type A participants would exhibit greater increases in blood pressure than Type B par...
