■导致缺铁性贫血的两个重要病因,和营养不良给撒哈拉以南非洲带来了巨大的公共卫生挑战,是土壤传播的蠕虫和疟疾。这项研究进行了每周补充铁-叶酸(WIFAS)对撒哈拉以南非洲学龄儿童和青少年的营养和一般健康的影响,我们进行了系统评价和荟萃分析.
■为了找到本研究的相关出版物,2023年5月20日,对五个数据库进行了彻底搜索:Pubmed(MEDLINE),WebofScience,Scopus,科克伦图书馆,谷歌学者。此外,2023年8月23日进行了搜索,以捕获任何新记录.这些研究的纳入标准是基于学龄儿童和青少年人群,随机对照试验,以及对WIFAS影响的调查。通过人体测量学变化来测量感兴趣的结果,疟疾,蠕虫再感染.
■对11篇文章的系统评价显示,WIFAS将青少年血吸虫病再感染的风险显着降低了21%(风险比=0.79,95CI:0.66,0.97;异质性I2=0.00%,P=0.02)。然而,对疟疾再感染风险无显著影响(风险比=1.02,95CI:0.92,1.13;异质性I2=0.00%,P=0.67)或A.Lumbricoides再感染(风险比=0.95,95CI:0.75,1.19;异质性I2=0.00%,P=0.65)。此外,分析表明,补充铁叶酸对学龄儿童的身高和身高的年龄Z评分(HAZ)没有显着影响(Hedge'sg-0.05,95CI:-0.3,0.2;异质性I2=0.00%,P=0.7)和(套期保值g0.12,95CI:-0.13,0.37;异质性I2检验=0.00%,P=0.36)。
■WIFAS在降低青少年血吸虫病再感染风险方面的有效性已被证明大于安慰剂或无干预。此外,补充铁-叶酸的叙事合成已成为促进体重变化的潜在公共卫生干预措施.然而,WIFAS和蛔虫病之间没有显着关联,毛虫病,还有钩虫.此外,WIFAS对身高和疟疾影响的证据的确定性很低,因此尚无定论。然而,WIFAS对血吸虫病有效性的证据的确定性是中等的。即使机制需要进一步研究,WIFAS也可以作为解决青少年血吸虫病的全面公共卫生战略的一部分来实施。

UNASSIGNED: Two significant etiological factors contributing to iron deficiency anemia, and undernutrition posing substantial public health challenges in Sub-Saharan Africa, are soil-transmitted helminths and malaria. This study carried out the effect of weekly iron-folic acid supplementation (WIFAS) on the nutrition and general health of school-age children and adolescents in Sub-Saharan Africa, a systematic
review and meta-analysis have been conducted.
UNASSIGNED: To find pertinent publications for this study, a thorough search was carried out on May 20, 2023, across five databases: Pubmed (MEDLINE), Web of Science, Scopus, Cochrane Library, and Google Scholar. In addition, a search was conducted on August 23, 2023, to capture any new records. The inclusion criteria for the studies were based on school-age children and
adolescent populations, randomized controlled trials, and investigations into the effects of WIFAS. The outcomes of interest were measured through anthropometric changes, malaria, and helminthic reinfection.
UNASSIGNED: A systematic
review of 11 articles revealed that WIFAS significantly decreased the risk of schistosomiasis reinfection by 21% among adolescents (risk ratio = 0.79, 95%CI: 0.66, 0.97; heterogeneity I 2 = 0.00%, P = 0.02). However, no significant impact was observed on the risk of malaria reinfection (risk ratio = 1.02, 95%CI: 0.92, 1.13; heterogeneity I 2 = 0.00%, P = 0.67) or A. Lumbricoides reinfection (risk ratio = 0.95, 95%CI: 0.75, 1.19; heterogeneity I 2 = 0.00%, P = 0.65). Moreover, the analysis demonstrated that there is no significant effect of iron-folic acid supplementation in measured height and height for age Z-score (HAZ) of the school-age children (Hedge\'s g -0.05, 95%CI: -0.3, 0.2; test for heterogeneity I 2 = 0.00%, P = 0.7) and (Hedge\'s g 0.12, 95%CI: -0.13, 0.37; test for heterogeneity I 2 = 0.00%, P = 0.36) respectively.
UNASSIGNED: The effectiveness of WIFAS in reducing the risk of schistosomiasis reinfection in adolescents has been demonstrated to be greater than that of a placebo or no intervention. Additionally, the narrative synthesis of iron-folic acid supplementation has emerged as a potential public health intervention for promoting weight change. However, there was no significant association between WIFAS and Ascariasis, trichuriasis, and hookworm. Moreover, the certainty of the evidence for the effects of WIFAS on height and malaria is low and therefore inconclusive. Whereas, the certainty of the evidence for the effectiveness of WIFAS on Schistosomiasis is moderate. Even though the mechanisms need further research WIFAS may be implemented as part of a comprehensive public health strategy to address schistosomiasis in adolescents.
