The prevalence of varicose veins (VV) and of chronic venous insufficiency (CVI) was studied among 1755 adults over 15 years of age (443 men and 1312 women). These people attended the University Health Center in Botucatu, a country town in the State of Sao Paulo, Brazil, for routine examination or for any disease complaints. The prevalence of all grades of VV not including telangiectasis and reticular varices grade I was 47.6% (37.9% in men and 50.9% in non-pregnant women). The prevalence of VV recorded as moderate or severe was 21.2%. The more severe form of CVI with active or healed ulcer was present in 3.6% of the subjects (2.3% of men and 4% of women). For only 5.5% of the patients was VV or CVI the reason for medical consultation. The prevalence of VV increased with age and number of pregnancies and was greater among white than non-white people. Working posture or posture adopted for defaecation did not influence the prevalence of VV. Our data show the prevalence of VV and CVI to be higher or as high as the prevalence found in developed western countries. We therefore propose that studies of these conditions should be included in epidemiological surveys of other developing areas or countries, so that if data similar to ours are verified prophylaxis and early treatment could be included in health planning for these areas with the aim of reducing future morbidity and the related social onus.
在1755名15岁以上的成年人（443名男性和1312名女性）中研究了静脉曲张（VV）和慢性静脉功能不全（CVI）的患病率。这些人前往巴西圣保罗州一个乡村小镇博图卡图的大学健康中心进行常规检查或因任何疾病主诉就诊。不包括毛细血管扩张和I级网状静脉曲张的所有等级VV的患病率为47.6%（男性为37.9%，非妊娠女性为50.9%）。记录为中度或重度的VV患病率为21.2%。有活动期或已愈合溃疡的更严重形式的CVI在3.6%的受试者中存在（男性为2.3%，女性为4%）。仅5.5%的患者因VV或CVI就诊。VV的患病率随年龄和妊娠次数增加，且白人高于非白人。工作姿势或排便姿势不影响VV的患病率。我们的数据显示，VV和CVI的患病率高于或与西方发达国家的患病率一样高。因此，我们建议在其他发展中地区或国家的流行病学调查中纳入对这些疾病的研究，以便如果验证了与我们相似的数据，可以将预防和早期治疗纳入这些地区的健康规划，以减少未来的发病率和相关的社会负担。
