Objective  To assess the efficiency of iodised salt on iodine deficiency disorders.
Methods  we searched MEDLINE (1996 to December 2009), EMbase (1974 to December 2009), The Cochrane Library (Issue 4, 2009), Current Controlled Trials, The National Research Register, CBM (1983 to December 2009) and CNKI (1994 to December 2009), and traced the literature of the reference. The included objects were the resident of the iodine deficiency area and the age, the race. The sex was not limited. The fortified salt and the iodized salt effects were compared and the research quality was evaluated. Meta-analyses were conducted by the RevMan5.0 software.
Results  Eight studies involving 1 503 people were included. The goiter prevalence of the fortified salt which combined iodine with iron was lower than that of iodised salt [MD=1.22, 95%CI (0.90, 1.54)]. So was the thyroid gland volume [OR=1.88, 95%CI(1.01, 3.47)]. But the fortified salt which combined iodine with VA did not show this.
Conclusion  The fortified salt and the iodized salt can obviously improve the iodine nutritional status of people. The fortified salt has enhanced the effect while the iodized salt prevents iodine deficiency disorders, but more high grade randomized controlled trials are needed to confirm this.
