Using a systematic review of all available studies between 1991 and 2011, the prevalence of food insecurity in the Islamic Republic of Iran was estimated. After document evaluation and data aggregation, studies were analysed in separate categories based on the methods used: dietary recall, household income/expenditure or experiential/perception-based surveys. Meta-analysis of dietary-recall studies showed small non-significant increases between 1994 and 2004 in the prevalence of mild (from 8.8% to 9.3%) and moderate food insecurity (from 5.4% to 5.6%). Severe food insecurity was 3.8% and 3.7% in 1994 and 2004 respectively. Prevalence of food insecurity (moderate to severe) based on household income/expenditure surveys was consistently reported to be 10%. A separate meta-analysis of experiential/perception-based studies revealed rates of mild, moderate and severe food insecurity of 28.6%, 14.9% and 6.0% respectively. By combining study results in this manner makes it possible to come up with more realistic estimates for evidence-informed policy-making, until development of a national food insecurity surveillance system.
通过对1991年至2011年间所有可得研究进行系统综述，对伊朗伊斯兰共和国粮食不安全状况的患病率进行了估算。在文献评估和数据汇总之后，根据所使用的方法将研究分为不同类别：饮食回忆法、家庭收入/支出法或基于经验/认知的调查法。对饮食回忆研究的荟萃分析显示，1994年至2004年间，轻度粮食不安全状况的患病率（从8.8%升至9.3%）和中度粮食不安全状况的患病率（从5.4%升至5.6%）有小幅但不显著的上升。1994年和2004年严重粮食不安全状况的患病率分别为3.8%和3.7%。基于家庭收入/支出调查得出的粮食不安全状况（中度至重度）患病率始终为10%。对基于经验/认知的研究进行的另一项荟萃分析显示，轻度、中度和重度粮食不安全状况的发生率分别为28.6%、14.9%和6.0%。通过以这种方式合并研究结果，在国家粮食不安全监测系统建立之前，有可能得出更现实的估计值，以用于基于证据的政策制定。
