The Sahel region is projected to be highly impacted by the more frequent hazards associated with climate change, including increased temperature, drought and flooding. This systematic review examined the evidence for climate change-related health consequences in the Sahel. The databases used were Medline (PubMed), Embase (Ovid), Web of Science (Clarivate) and CABI Global Health. Hand searches were also conducted, which included directly engaging Sahelian researchers and hand-searching in the African Journals Online database. Of the 4153 studies found, 893 were identified as duplicates and the remaining 3260 studies were screened (title and abstract only) and then assessed for eligibility. A total of 81 studies were included in the systematic review. Most studies focused on vector-borne diseases, food security, nutrition and heat-related stress. Findings suggest that mosquito distribution will shift under different climate scenarios, but this relationship will not be linear with temperature, as there are other variables to consider. Food insecurity, stunting (chronic malnutrition) and heat-related mortality are likely to increase if no action is taken owing to the projected impact of climate change on environmental factors and agriculture. Seventy-one per cent of manuscripts ( = 58) had first authors from institutions in North America or Europe, of which 39.7% ( = 23) included co-authors from African institutions.
预计萨赫勒地区将受到与气候变化相关的更频繁灾害的严重影响，这些灾害包括气温升高、干旱和洪水。本系统评价考察了萨赫勒地区与气候变化相关的健康后果的证据。所使用的数据库有Medline（PubMed）、Embase（Ovid）、Web of Science（科睿唯安）和CABI全球健康数据库。还进行了手工检索，包括直接与萨赫勒地区的研究人员联系以及在《非洲在线期刊》数据库中进行手工检索。在所发现的4153项研究中，893项被确定为重复研究，其余3260项研究（仅标题和摘要）经过筛选，然后评估其是否符合纳入标准。共有81项研究被纳入该系统评价。大多数研究集中于媒介传播疾病、粮食安全、营养和与热相关的应激。研究结果表明，在不同气候情景下蚊子的分布将会改变，但这种关系与温度并非呈线性关系，因为还有其他变量需要考虑。由于预计气候变化会对环境因素和农业产生影响，如果不采取行动，粮食不安全、发育迟缓（慢性营养不良）和与热相关的死亡率可能会增加。71%的手稿（n = 58）的第一作者来自北美或欧洲的机构，其中39.7%（n = 23）的手稿包含来自非洲机构的共同作者。
