In an epidemiological examination outside specialized laboratories we investigated the test-retest stability of blood pressure (BP) and heart rate (HR) reactions to standardized mental stress in 136 men (mean age 44 +/- 7 years) with complaints of mental and physical fatigue. Repetitive stress testing was performed at 4-week intervals on four occasions. On all four occasions stress levels differed significantly from baseline levels (P less than 0.001). Baseline conditions for BP and HR were significantly correlated at 4-week and 8-week intervals (P less than 0.001). Cardiovascular reactivity to mental stress was also stable over a 4, 8, and 12-week period. We conclude that psychophysiological reactivity can be assessed with good reliability under field conditions.
Wie kann man die perinãtale Kindersterblichkeit bekämpfen? Von H u g d i e t e r N o a c k Die Problemstellung der Arbeit regt zu der Gegenfrage an: ,,Ist die perinatale Kindersterblichkeit etwa nicht bekämpfbar? Wir wissen, daß die Sterblichkeit der Kinder vor, während und in den ersten 10 Tagen nach der Geburt seit 50 Jahren ausgenommen einige Spezialkliniken -etwa gleich geblieben ist, während im gleichen Zeitraum die übrige Kindersterblichkeit sehr erheblich reduziert werden konnte. Es ist aber zu bedenken, daß die Geburtshilfe, die ja in der Hauptsache für die Bekämpfung der peririatalen Letalität verantwortlich ist, bisher genügend damit beschäftigt war, das mütterliche Geburtsrisiko
