Influence of shift work in nursing on sleep and circadian blood pressure and rhythm / 心血管康复医学杂志

ABSTRACT

Objective: To explore influence of shift work in nursing on sleep and circadian blood pressure and rhythm. Methods: A total of 29 shift nurses, who worked in our hospital for a long period, were enrolled as shift nurse group. Another 32 day shift nurses were regarded as day shift nurse control group（control group）. Both groups received Pittsburgh sleep quality index (PSQI) assessment and 24h ambulatory blood pressure monitoring (ABPM). Results: Compared with control group, PSQI assessment showed that most factor scores and PSQI total score [(8.67±2.16) scores vs. (11.98±3.30) scores] significantly increased in shift nurse group（P<0.05~0.01）; 24h ABPM showed that mean nighttime SBP [(106.51±12.94) mmHg vs. (115.74±13.72) mmHg] and nighttime DBP [(71.23±9.76) mmHg vs. (74.96±10.68) mmHg] significantly rose in shift nurse group, P<0.05; Mean SBP decreasing rate [(7.84±1.52)% vs. (3.66±1.47)%] and mean DBP decreasing rate [(6.55±1.39)% vs. (2.83±0.51)%], SBP dipper percentage (59.38% vs. 31.03%) and DBP dipper percentage (68.75% vs. 27.59%) significantly reduced, SBP non-dipper percentage (40.63% vs. 68.97%) and DBP non-dipper percentage (31.25% vs. 72.41%) significantly rose in shift nurses group, P<0.05~0.01.Conclusions: There exists definite somnipathy and significant change of circadian blood pressure and rhythm in shift nurses.
