A growth curve analysis was used to examine estimated longitudinal decline (over 19 years) on the Wechsler Adult Intelligence Scale (WAIS; D. Wechsler, 1955) in relation to arterial hypertension and blood pressure (BP) for 55 men and 85 women (40 to 70 years old) who were free from overt major coexisting diseases. BP was associated with longitudinal decline for Visualization-Performance (VP) ability and Speed. Hypertension was a weaker predictor of VP and was unrelated to Speed. Age effects on VP were overestimated when averaged BP level, particularly systolic BP, was not controlled statistically. It was concluded that initial BP level and hypertension predict age-related longitudinal decline in specific major abilities assessed by the WAIS but that BP averaged over examinations is a stronger predictor.
采用生长曲线分析，研究了55名男性和85名女性（40至70岁）在韦氏成人智力量表（WAIS；D.韦克斯勒，1955）上的估计纵向衰退（19年期间）与动脉高血压和血压（BP）之间的关系，这些人无明显的主要共存疾病。血压与视觉化-操作（VP）能力和速度的纵向衰退有关。高血压对VP的预测作用较弱，且与速度无关。当未对平均血压水平（尤其是收缩压）进行统计学控制时，年龄对VP的影响被高估。研究得出结论，初始血压水平和高血压可预测WAIS评估的特定主要能力中与年龄相关的纵向衰退，但多次检查的平均血压是更强的预测指标。
