Objectives: To assess the associations of a clock drawing task with hormone replacement therapy and other factors in older women.
Design: Group comparisons.
Setting: Leisure World Laguna Hills, retirement community in southern California.
Participants: Two hundred ninety-two postmenopausal women who were analyzed for lipoprotein levels in 1987-88 were contacted by postal survey, which included a clock drawing task, in 1992; 168 women who drew normal clocks were compared with 46 who drew abnormal or blank clocks.
Measurements: Clock drawings; lipoprotein cholesterol levels; serum progesterone, estrone, estradiol, and steroid hormone binding globin levels; self-reported data on smoking, alcohol intake, prior medical diagnoses, and use of certain medications including hormone replacement therapy and analgesics.
Results: Women with normal clocks had significantly lower total cholesterol (P = .01), LDL cholesterol (P = .03), and serum progesterone levels (P = .03). They weighed, on average, 5 more pounds at the time of last menstrual period (P = .05), were more likely to use combined hormonal replacement therapy (P = .06), and were less likely to use acetaminophen daily (P = .02) than women with abnormal clocks. Serum estrone and estradiol levels did not differ significantly between women with normal and abnormal clocks.
Conclusion: The associations found here suggest that high serum cholesterol and progesterone levels might have a negative effect on clock drawing performance. Acetaminophen may also be related to worse performance on this task.
