STANDING AND SITTING POSTURES AT WORK AND SYMPTOMS OF VENOUS INSUFFICIENCY - RESULTS FROM QUESTIONNAIRES AND A DOPPLER ULTRASOUND STUDY.

Chronic venous insufficiency is the most common vascular disease. One of the major risk factors for its development is long-term sitting or standing in the same position, and the nature of the work performed. The aim of the study was to evaluate the incidence of chronic venous insufficiency in a group of persons employed in workplaces with a predominance of standing or sitting positions, and to determine work-related and non-work risk factors. The research used two tools:- questionnaires and medical examinations. The survey comprised a total of 500 people, including 238 men (47.6%) and 262 women (52.4%), aged 25 to 60 years, 39.75 ± 10.80 years old on average. In addition, a group of 100 randomly selected people was subjected to medical examinations in order to confirm or exclude chronic venous insufficiency symptoms in the study group. The study showed a statistically significant correlation between postures adopted at work and the symptoms of chronic venous insufficiency of the lower limbs.
