[背景]评估归因于环境空气中细颗粒物（PM2.5）长期暴露所致的疾病负担，需要具备相对风险（RR）函数形状和幅度两方面的知识。然而，在世界上很多观察到高PM2.5环境浓度的地方，都缺乏足够的直接证据确定死亡率RR函数的形状。

背景呼吸道合胞病毒(respirat.ry syncyt.al virus,RSV)是引起婴幼儿急性下呼吸道感染最常见的病原体。此前估计,2015年全球60月龄以下儿童共发生3 310万次RSV相关急性下呼吸道感染,导致118 200人死亡。此后,几项社区监测研究获得了对RSV相关社区死亡的更精确估计。本文旨在更新2019年全球、地区和国家层面60月龄以下儿童RSV相关急性下呼吸道感染的发病率和死亡率,重点关注总体死亡率和在研RSV免疫制剂针对的更窄的婴儿年龄组。方法检索获得MEDLINE、Embase、Global Healt.、CINAHL、Web of Science、LILACS、OpenGrey、中国知网、万方和维普数据库2017—2020年发表文献中的新数据,并纳入RSV GEN合作者提供的未发表数据,以扩展全球RSV疾病负担数据集。纳入的研究符合以下条件:报告了社区中或需要住院治疗的60月龄以下儿童RSV原发性急性下呼吸道感染的数据;报告了至少连续12个月的数据,但院内病死率或RSV季节性定义明确的地区除外;报告了RSV相关急性下呼吸道感染的发病率、住院率、院内病死率或急性下呼吸道感染住院的RSV阳性比例。如果病例定义不明或应用不一致、RSV感染未经实验室确认或仅基于血清学检测、报告的急性下呼吸道感染病例少于50例,则排除该研究。本研究应用广义线性混合效应模型(generalized linear mixed-effect. model,GLMM)估计了2019年全球和地区(按国家发展状况和世界银行收入分类)RSV相关急性下呼吸道感染的发病率、住院率和院内病死率;通过基于危险因素的模型估计了国家层面RSV相关急性下呼吸道感染的发病率;通过GLMM开发了新模型,纳入最新的RSV社区死亡率数据,用于估计RSV的总体死亡率。本综述已在PROSPERO注册(CRD42021252400)。结果除了先前综述中纳入的317项研究外,还纳入了113项符合条件的新研究以及51项未发表的研究,共计481项研究。据估计,2019年全球60月龄以下儿童中,共发生3 300万(置信区间为2 540万~4 460万)次RSV相关急性下呼吸道感染,导致360万(290万~460万)例住院、26 300(15 100~49 100)例院内死亡以及101 400(84 500~125 200)例可归因于RSV的总死亡数。在0~6个月的婴儿中,共发生660万(460万~970万)次RSV相关急性下呼吸道感染,导致140万(100万~200万)例住院、13 300(6 800~28 100)例院内死亡以及45 700(38 400~55 900)例可归因于RSV的总死亡数。60月龄以下和28 d~6月龄儿童的死亡中分别有2.0%(置信区间为1.6%~2.4%)和3.6%(3.0%~4.4%)归因于RSV。在各年龄组中,95%以上的RSV相关急性下呼吸道感染事件和97%以上的可归因于RSV的死亡事件都发生在中低收入国家。结论 RSV显著增加了全球60月龄以下儿童的发病和死亡负担,尤其是在出生后前6个月和中低收入国家。本研究强调了全球RSV疾病的总体死亡率负担,60月龄以下儿童中,每50例死亡就有1例可归因于RSV;28 d至6个月大的婴儿中,每28例死亡就有1例可归因于RSV。每1例RSV相关急性下呼吸道感染院内死亡,对应社区中约3例可归因于RSV的死亡。对6月龄内婴儿提供保护的RSV被动免疫计划有望对减轻RSV疾病负担,但实施计划时,仍需要更多数据来了解RSV疾病负担高峰可能向大龄转移的影响。
