To summarize the rhythm variation of 24-hour ambulatory blood pressure (ABP) between Chinese male shift workers and day workers.Methods:
176 subjects, including 77 shifters and 99 day workers, were collected information on clinical characteristics and laboratory data, performed measurements of ABP. Day-nocturnal and awake-sleep rhythm variation of ABP were compared between groups.Results:
24-hour ABP was similar in two groups. Day-nocturnal rhythm variation was disappeared among the shifters, while existed among the day workers, showed a statistically significant difference, even after adjustment for co-variables (P = 0.0008). Whereas, awake-sleep rhythm was both existed among two groups, but the group of day workers was higher (P < 0.01).Conclusion:
Rhythm variation of 24-hour ambulatory blood pressure among shifters was along with awake-sleep pattern, rather than day-nocturnal one.
