To determine the association of public versus private health care utilization and prevalence of Trichomonas vaginalis in Maringá, Paraná, Brazil.
A retrospective study on the results of 133,966 cytology examinations of patients from the Brazilian Public Health System (better socio-economic status, SES) and from the Private Network (low SES) done by the Souza Anatomy Laboratory in Maringá, Brazil, from 2004 to 2007.
In patients using the SUS, the prevalence of trichomoniasis was 1.44% (n = 782), higher (P < 0.0001) than for RP users (0.18%, n = 147). The infection predominated in age ranges of the 30-39 years and 40-49 years old from the SUS (P < 0.0001) and in ages ranges from 40 to 49 years old from the RP (P < 0.0001). The infection prevalence and age range did not vary among the 4 years (P > 0.05).
The prevalence of Trichomonas spp. was low and stable in both populations in the 4 years, indicating an equilibrium in terms of numbers of this agent in Maringá, Paraná, Brazil. The results corroborate the hypothesis that SES may influence the epidemiology of trichomoniasis. The prevalence of the infection increases with age, a phenomenon not observed with other sexually transmitted infections, such as gonorrhoea or Chlamydia trachomatis.
在巴西帕拉纳州马雷格市，确定公共与私人医疗保健的利用与阴道毛滴虫病流行率之间的关系。
这是一项回顾性研究，分析了巴西 Souza 解剖实验室在 2004 年至 2007 年间，对来自巴西公共卫生系统（社会经济地位较高）和私人网络（社会经济地位较低）的 133966 例细胞学检查患者的结果。
在使用 SUS 的患者中，滴虫病的流行率为 1.44%（n = 782），高于 RP 使用者（0.18%，n = 147）（P < 0.0001）。感染在 SUS 年龄组 30-39 岁和 40-49 岁之间（P < 0.0001）和 RP 年龄组 40-49 岁之间更为常见（P < 0.0001）。在 4 年中，感染的流行率和年龄范围没有变化（P > 0.05）。
在这 4 年中，两种人群中阴道毛滴虫的流行率都较低且稳定，表明巴西帕拉纳州马雷格市该病原体数量达到平衡。研究结果证实了 SES 可能影响滴虫病流行病学的假说。感染的流行率随年龄增加而增加，这一现象与其他性传播感染（如淋病或沙眼衣原体）不同。
