Abstract
OBJECTIVE: To examine the effect of age on activity patterns, including circadian rhythms and levels, after coronary artery bypass surgery (CABS).
DESIGN: Repeated measures, correlational.
SETTING: Northeastern university-affiliated tertiary coronary care center.
SUBJECTS: Eight middle-aged (mean age = 57 years) and 14 older (mean age = 72 years) adults who had undergone first, isolated CABS.
OUTCOME MEASURES: Wrist actigraph measures of levels (daytime activity) and circadian patterns of activity (acrophase, amplitude, percent rhythm, mesor), self-reported postoperative clinical activity milestones, and Sickness Impact Profile subscales of ambulation dysfunction and sleep-rest.
INTERVENTION: Measurement of activity over postoperative days 2 through 5, including wrist actigraphy, Sickness Impact Profile ambulation and sleep-rest subscales, and daily clinical activity milestones.
RESULTS: Repeated measures ANOVA was used in the data analysis. Statistically significant increases were found in percent rhythm (P
CONCLUSION: Both middle-aged and older adults increase daily activity and the strength of circadian activity pattern over days 2 through 5. However, these variables increase more rapidly in middle-aged adults after essentially identical levels on postoperative days 2 and 3.
