Birth defects are structural or functional defects present at birth and are caused by different factors that affect intrauterine development. They are the second most common cause of death under five years of age in Latin America and the Caribbean. In Bogotá and Cali, Colombia, there are two surveillance programs established to evaluate the prevalence of them. The purpose of the following article is to describe the experience and results of the surveillance of the Birth Defects Surveillance Programs in Bogotá and Cali, Colombia, 2002-2019. The information was taken from the surveillance programs that have an active hospital system in some institutions of the city (ECLAMC modality), and use data from the passive national system (Sistema Nacional de Vigilancia en Salud Pública - SIVIGILA) to expand their coverage. From 2002 until 2019, 1,289.650 births have been monitored through one of the surveillance programs, including both methodologies. The importance of surveillance programs relies on the amount of data obtained that allows the development of research, the detection of potential changes throughout time, and the guidance of public policies to improve promotion and prevention strategies.

2002-2019 年哥伦比亚波哥大和卡利出生缺陷监测和后续计划的描述和结果

出生缺陷是出生时存在的结构或功能缺陷，由影响子宫内发育的不同因素引起。它们是拉丁美洲和加勒比地区五岁以下儿童死亡的第二大常见原因。在哥伦比亚的波哥大和卡利，建立了两个监测计划来评估它们的流行情况。以下文章的目的是描述 2002-2019 年哥伦比亚波哥大和卡利出生缺陷监测计划的监测经验和结果。该信息取自在该市某些机构（ECLAMC 模式）中拥有主动医院系统的监测计划，并使用来自被动国家系统（Sistema Nacional de Vigilancia en Salud Pública - SIVIGILA）的数据来扩大其覆盖范围。从 2002 年到 2019 年，1,289。通过其中一项监测计划（包括两种方法）监测了 650 名新生儿。监测计划的重要性取决于所获得的数据量，这些数据量可以促进研究的发展、随时检测潜在的变化，以及公共政策的指导以改进促进和预防策略。
