Abstract：
A controversy about the increase or decline of vasectomy is emerging; however, the evidence is still scarce in Latin America. This ecological study analyzed the vasectomy and sexual transmitted diseases (STD) trends over a period of 10 years in Chile and determined if there is any relationship between them. We conducted a mixed ecological study using secondary and representative data on the number of vasectomies and STD cases from 2008 to 2017. Vasectomy rates were calculated for age-specific groups of men aged 20-59 years, and specific STD (HIV, chlamydia, gonorrhea, trichomoniasis, and syphilis) for the same period. Multivariate negative binomial regression models were fitted to evaluate rate trends and relationships. The mean vasectomy age was 40.3 years, with no significant differences between the years of the study (p = 0.058). The overall vasectomy rate significantly increased from 2008 to 2017 (p < 0.001), with differences between age groups (p < 0.001). The most significant increase was observed in men aged 30-49 (p < 0.001). The STD rates significantly increased (p < 0.05) during the study period. A significant positive correlation was found between vasectomy and gonorrhea incidence rates (p = 0.008) and an inverse correlation was found with hepatitis B incidence rates (p = 0.002). Vasectomy trends and STD rates significantly increased from 2018 to 2017 in Chile. especially among men aged 30-49 years. The relationship between vasectomy and STD increments suggests a new risk factor for reproductive and sexual health policies to aid controlling the HIV and STD epidemic.
摘要：
关于输精管切除术的增加或减少的争议正在出现；然而，在拉丁美洲，证据仍然很少。这项生态研究分析了智利10年来的输精管结扎和性传播疾病（STD）趋势，并确定它们之间是否有任何关系。我们使用2008年至2017年输精管切除术和性病病例数的次要和代表性数据进行了混合生态学研究。计算了20-59岁男性的特定年龄段的输精管切除术率，和特定的性病(艾滋病毒，衣原体,淋病,滴虫病,和梅毒）同期。拟合多元负二项回归模型来评估率趋势和关系。平均输精管切除术年龄为40.3岁,研究年份之间没有显着差异（p=0.058）。从2008年到2017年，输精管结扎率显着增加（p<0.001），年龄组之间存在差异（p<0.001）。在30-49岁的男性中观察到最显著的增加(p<0.001)。STD发生率在研究期间显著增加(p<0.05)。输精管结扎术和淋病发病率之间存在显着正相关（p=0.008），与乙型肝炎发病率呈负相关（p=0.002）。从2018年到2017年，智利的输精管结扎趋势和性病发病率显着增加。尤其是30-49岁的男性。输精管结扎术与性病增加之间的关系为生殖和性健康政策提供了新的风险因素，以帮助控制艾滋病毒和性病的流行。
