摘要

目的:本研究旨在评估巴西育龄妇女、孕妇和哺乳期妇女中b族复合维生素缺乏症的患病率。方法:本系统综述分析了截止到2023年8月发表的横断面和队列研究,这些研究被MEDLINE、SciELO、LILACS、Scopus、Embase、Web of Science和巴西论文数字图书馆收录。通过联系巴西公立大学的研究人员获得了更多的数据。包括使用生化标记评估缺乏率的研究。两位审稿人独立选择研究,提取数据,并使用Joanna Briggs Institute工具评估方法学质量。结果:在确定的3772份记录中,纳入了13项研究。只有叶酸(n = 13)、B12 (n = 11)和B6 (n = 1)缺乏被调查,所有的研究都是横断面的。B12缺乏症的患病率差异很大,最高可达29.4%。叶酸缺乏率普遍较低,只有一项研究报告的缺乏率高达37%。其他复合b族维生素没有得到充分的研究。大多数研究都有方法上的局限性,特别是样本量小。研究间的显著异质性限制了合并定量荟萃分析的可行性。结论:显然需要在巴西所有地区进行更有力的研究,以提高对维生素缺乏率的了解,并支持有效的营养干预措施。系统评价注册号:PROSPERO CRD42020188474。

Deficiency of B vitamins in women of childbearing age, pregnant, and lactating women in Brazil: a systematic review.

Objective: This study aimed to evaluate the prevalence of B-complex vitamin deficiencies in Brazilian women of childbearing age, pregnant women, and lactating women.

Methods: This systematic review analyzed cross-sectional and cohort studies published up to August 2023 and indexed in MEDLINE, SciELO, LILACS, Scopus, Embase, Web of Science, and the Brazilian Digital Library of Theses and Dissertations. Additional data were obtained by contacting researchers from Brazilian public universities. Studies assessing deficiency rates using biochemical markers were included. Two reviewers independently selected studies, extracted data, and assessed methodological quality using the Joanna Briggs Institute tool.

Results: Of the 3772 records identified, 13 studies were included. Only folate (n = 13), B12 (n = 11), and B6 (n = 1) deficiencies were investigated, and all studies were cross-sectional. B12 deficiency prevalence varied widely, reaching up to 29.4%. Folate deficiencies were generally low, with only one study reporting a rate as high as 37%. Other B-complex vitamins were insufficiently studied. Most studies had methodological limitations, particularly small sample sizes. The significant heterogeneity across studies limited the feasibility of a pooled quantitative meta-analysis.

Conclusion: There is a clear need for more robust studies across all Brazilian regions to improve understanding of vitamin deficiency rates and to support effective nutritional interventions.

期刊介绍: Systematic Reviews encompasses all aspects of the design, conduct and reporting of systematic reviews. The journal publishes high quality systematic review products including systematic review protocols, systematic reviews related to a very broad definition of health, rapid reviews, updates of already completed systematic reviews, and methods research related to the science of systematic reviews, such as decision modelling. At this time Systematic Reviews does not accept reviews of in vitro studies. The journal also aims to ensure that the results of all well-conducted systematic reviews are published, regardless of their outcome.
