Summary
Varicose vein prevalence is linked to age, gender, and family history in German adults. Genetics, particularly maternal history, and prolonged sitting are key risk factors, while smoking shows a protective effect.
Area of Science:
- Epidemiology
- Vascular Medicine
- Public Health
Background:
- Varicose veins represent a significant public health concern with multifactorial etiology.
- Understanding population-specific prevalence and risk factors is crucial for targeted prevention strategies.
Purpose of the Study:
- To ascertain the prevalence of varicose veins within the German population.
- To identify and quantify significant risk factors associated with varicose vein development.
Main Methods:
- Analysis of data from the Duesseldorf/Essen civil servants study (1989-1993).
- Inclusion of 9,935 employees who completed questionnaires and underwent clinical examinations.
- Classification of venous findings using the CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification system; analysis focused on CEAP classes 0 and II.
Main Results:
- Age and gender are primary risk factors for varicose veins (ORs: male age 3.4, female age 6.5, gender 2.3).
- In females, oral contraception use was a frequent risk factor; prolonged sitting was common in both genders.
- Heredity emerged as the most significant risk factor after adjusting for age and gender (OR 5.2 for both parents), followed by standing posture (OR 2.2). Smoking demonstrated a protective effect (OR 0.66).
Conclusions:
- Family history is the most critical risk factor for varicose veins in the German population, alongside age and gender.
- While other factors like sitting posture and oral contraceptives show influence, their overall relevance is moderated by frequency and effect size in this cohort.
