Impacts of noise pollution on arterial systolic blood pressure, diastolic blood pressure, heart pulse rate and blood oxygen saturation of nurses in Duhok hospitals-Iraq

Abstract EN

This study had been done to estimate the effect of noise pollution on the systolic and diastolic blood pressure (SBP, DBP), heart rate (HR) and oxygen saturation (SpO2) for 41 nurses, aged 18-43 years old, in two selected hospitals of Duhok Governorate.

These two hospitals (Azadi and Shelan Hospitals) where chosen randomly in different location of Duhok City and the tests were done for both male and female before exposure to noise and after 4 to 5 hours of work.

The minimum and maximum value of sound pressure level measured during working hour in Azadi hospital (19 - 94dB) while in Shelan Hospital (24-86dB) respectively.

Whereas, the average of sound pressure level (SPL) measured in both selected Hospitals were (66.5 and 58.5dB) which were perceived below the limited threshold (85 dB).

Person’s correlation coefficient (r) and P-values for all dependent variable were calculated.

r for SBP, DBP, HPR and SpO2 were 0.141, 0.212, 0.511 and 0.412 respectively while P-value for all studied variable P > 0.05, these results indicate that there is no strong association between dependent variable and independent variable, sound pressure level (SPL).
