Summary
Standing work increases lower limb venous pressure and reactive oxygen species (ROS). Nurses in standing roles experienced higher ROS levels post-work, indicating potential health risks associated with prolonged standing occupations.
Area of Science:
- Occupational Health
- Vascular Physiology
- Biomedical Science
Background:
- Epidemiological studies link prolonged standing work to chronic venous insufficiency in lower limbs.
- Chronic venous insufficiency is associated with increased oxidative stress, a potential risk factor for systemic diseases.
Purpose of the Study:
- To compare lower limb venous pressure and reactive oxygen species (ROS) in nurses with standing vs. mobile work.
- To assess the impact of occupational posture on vascular and oxidative stress markers.
Main Methods:
- Evaluated 62 surgery room nurses (standing) and 65 outpatient nurses (mobile).
- Measured venous pressure and ROS levels before and after work shifts.
- Statistical analysis compared outcomes between the two groups.
Main Results:
- Both groups showed increased venous pressure after work.
- Nurses with standing occupations exhibited significantly higher post-work ROS levels compared to mobile nurses.
- Prolonged standing is associated with elevated oxidative stress markers.
Conclusions:
- Standing occupations contribute to increased venous pressure and oxidative stress.
- Occupational standing poses a risk for developing chronic venous insufficiency and related systemic health issues.
- Interventions to mitigate prolonged standing may reduce vascular and oxidative stress in workers.
