Epidemiological studies have reported an inconsistent relationship between dietary inflammatory index (DII) and upper aerodigestive tract (UADT) cancer risk. However, no systematic review or meta-analysis has been reported up to now. To quantify the association between DII and UADT cancer risk, we performed this meta-analysis.
The PubMed, EMBASE, Web of Science and Cochrane Library database were searched for relevant studies from inception December 2018. All case-control studies investigating the association between DII and UADT cancer risk were selected.
A total of 9 case-control studies were identified, involving 13,714 participants. The adjusted pooled OR of UADT cancer for the highest (the most pro-inflammatory diet) vs lowest (the most anti-inflammatory diet) DII categories were 2.27 (95% CI: 1.89-2.73). Subgroup analysis showed that individuals with the highest category of DII score were independently associated with esophagus cancer (OR = 2.53, 95% CI: 1.74-3.68), oral cavity cancer (OR = 2.23, 95% CI: 1.73-2.86), pharyngeal cancer (OR = 2.02, 95% CI: 1.54-2.64), and laryngeal cancer (OR = 2.05, 95% CI: 0.85-4.93).
This meta-analysis suggested that the most pro-inflammatory diets (the highest DII scores) are associated with increased UADT cancer risk. However, the association between DII and laryngeal cancer risk need to be further investigated.
流行病学研究报告了饮食炎症指数(DII)与上消化道(UADT)癌症风险之间的关系并不一致。然而,目前尚未有系统评价或荟萃分析的报道。为了量化DII与UADT癌症风险之间的关联,我们进行了这项荟萃分析。
检索PubMed、EMBASE、Web of Science和Cochrane图书馆数据库,以查找自2018年12月开始的相关研究。选择所有调查DII与UADT癌症风险之间关联的病例对照研究。
共确定了9项病例对照研究,涉及13714名参与者。最高(最促炎饮食)与最低(最抗炎饮食)DII类别下UADT癌症的调整后合并比值比为2.27(95%CI:1.89-2.73)。亚组分析表明,DII评分最高类别的个体与食管癌(OR = 2.53,95%CI:1.74-3.68)、口腔癌(OR = 2.23,95%CI:1.73-2.86)、咽癌(OR = 2.02,95%CI:1.54-2.64)和喉癌(OR = 2.05,95%CI:0.85-4.93)独立相关。
这项荟萃分析表明,最促炎的饮食(DII评分最高)与UADT癌症风险增加相关。然而,DII与喉癌风险之间的关联需要进一步研究。
