Food labelling is a global strategy recommended to reduce noncommunicable diseases. Few reviews, however, have focused on food label use in sub-Saharan Africa (SSA).
To determine the prevalence of food label use and describe determinants of food label use and purchasing decisions of adult consumers in SSA.
PubMed (Medline), Web of Science, Cochrane Central, and Google Scholar databases.
Search criteria included adults (aged ≥18 years), conducted in SSA, focusing on food label use or understanding and their determinants or determinants of food-purchasing decisions, and articles published in English.
Risk-of-bias assessment of included studies was done using the Joann Briggs Institute checklist for prevalence studies. Publication bias was assessed using funnel plots and Egger's test. Analysis included narrative synthesis and moderator and meta-analyses of food label use.
A total of 124 articles were found, of which 21 were included in the review. Of participants in the selected studies, 58% were female. About 80% reported food label use (either used sometimes or always) (70%-88%) (I2 = 97%; n = 6223), and regular use was estimated at 36% (28%-45%) (I2 = 97%; n = 5147). Food label use was influenced by level of income, education, employment status, and household size. Food-purchasing decisions were influenced by attributes such as expiry dates, price, and taste. Major recommendations reported were tailored education campaigns and reducing barriers to food label use.
Most (80%) of adults in SSA reported using food labels; however, only about one-third used them consistently. Demographic and situation factors determined patterns in food label use, whereas product attributes influenced food purchasing decisions. Complexity of these determinants requires adopting tailored, multisectoral, theory-driven programs to improve food label use.

食品标签是全球推荐的减少非传染性疾病的策略。然而，很少有综述聚焦于撒哈拉以南非洲（SSA）的食品标签使用情况。
确定 SSA 成年消费者食品标签使用情况的流行率，并描述食品标签使用情况和购买决策的决定因素。
PubMed（Medline）、Web of Science、Cochrane Central 和 Google Scholar 数据库。
搜索标准包括成年人（年龄≥18 岁）、在 SSA 进行、关注食品标签使用或理解及其决定因素或食品购买决策的决定因素的文章，以及以英语发表的文章。
使用 Joann Briggs 研究所用于流行率研究的清单对纳入研究进行偏倚风险评估。使用漏斗图和 Egger 检验评估发表偏倚。分析包括食品标签使用情况的叙述性综合以及调节变量和荟萃分析。
共发现 124 篇文章，其中 21 篇被纳入综述。在所选择研究的参与者中，58%为女性。约 80%的人报告说使用过食品标签（有时或总是使用）（70%-88%）（I2=97%；n=6223），并且定期使用估计为 36%（28%-45%）（I2=97%；n=5147）。食品标签的使用受到收入、教育、就业状况和家庭规模等因素的影响。食品购买决策受到保质期、价格和口味等属性的影响。报告的主要建议是开展有针对性的教育宣传活动和减少使用食品标签的障碍。
大多数（80%）的 SSA 成年人报告使用食品标签；然而，只有约三分之一的人经常使用。人口统计学和情况因素决定了食品标签使用模式，而产品属性则影响了食品购买决策。这些决定因素的复杂性要求采取有针对性的、多部门的、基于理论的方案来提高食品标签的使用。
