Objective  To systematically review current status of Chinese DRIs, and compare the similarities and differences between Chinese and global DRIs, so as to provide references for regulating Chinese DRIs.
Methods  Such database as PubMed, ISI Web of knowledge, The Cochrane Library, CBM, WanFang Data, CNKI and VIP were electronically searched from inception to May 31st, 2013. The reviewers independently screened studies according to inclusion and exclusion criteria, extracted data. Then, descriptive analysis was performed for basic information of literature, formulation of different DRIs, and DRIs distribution by different ages.
Results  Initially, a total of 588 articles were retrieved, 42 of which were finally included, involving 14 guidelines, 12 systematic reviews (SRs), and 16 original studies. The results showed that, WHO guidelines and global systematic reviews focused on iron and fat-soluble vitamins (A and D); the original studies in China focused not only on iron and vitamin A but also on protein, calcium, zinc, and selenium. The included guidelines focused mainly on population aged 3-18 years old and pregnant women; and except for those two kinds of population, SRs also paid attention to adults aged more than 18 years. The original studies of Chinese DRIs were concerned about all kinds of population, mainly focused adults aged 18-45 years and school children aged 6-12 years. Among 16 included original studies, 4 were concerned about men and 2 about women.
Conclusion  Chinese DRIs need urgent updates and supplement. As the largest developing country, China has different disease burdens, consumption levels, dietary patterns, nutrients’ content, and security levels, compared with developed countries and other developing countries. To develop evidence-based Chinese DRIs that are suitable for native health and Chinese local conditions, we should drawing lessons from the currently available best DRIs standards, methods and evidence based on Chinese actual conditions, disease burden, and expert opinion.
