In this study, we assessed the association between the dietary phytochemical index (DPI) and metabolic syndrome (MetS) among adults in a cross-sectional study. We enrolled 850 adult men and women aged 18-65 years who had been referred to health centers in Tehran, Iran. The DPI was calculated based on 8 components including fruits, vegetables, legumes, whole grains, soy products, nuts, seeds, olive, and olive oil. The odds ratio (OR) and 95% confidence interval (CI) of the MetS across quartiles of the DPI were calculated using the logistic regression analysis, adjusting for age, energy intake, marital status, education status, occupation, smoking status, physical activity, and body mass index. The mean age of participants was 44.7 ± 10.7, of whom 69% were women. The prevalence of MetS was 30.5%. The mean score of DPI in women and men was 36.2 ± 26.8 and 33.7 ± 24.7, respectively. There was no significant association between DPI and odds of MetS in men (OR,1.57; 95% CI, 0.64-3.84) and women (OR, 0.86; 95% CI, 0.50-1.49) in the fully adjusted model. There was an inverse association between DPI and increased risk of central obesity in women (OR, 0.54; 95% CI, 0.29-1.00; p trend = 0.03). There was no significant association between DPI and other components of the MetS in men and women. Finally, we observed no significant association between the DPI and the odds of MetS. However, the finding suggests that having a phytochemical-rich diet can be inversely associated with abdominal obesity.
在这项横断面研究中，我们评估了成年人群中饮食植物化学物质指数（DPI）与代谢综合征（MetS）之间的关联。我们纳入了850名年龄在18至65岁之间、被转诊至伊朗德黑兰健康中心的成年男性和女性。DPI基于水果、蔬菜、豆类、全谷物、豆制品、坚果、种子、橄榄和橄榄油这8种成分进行计算。使用逻辑回归分析计算DPI四分位数中MetS的比值比（OR）和95%置信区间（CI），并对年龄、能量摄入、婚姻状况、教育程度、职业、吸烟状况、身体活动和体重指数进行了调整。参与者的平均年龄为44.7±10.7岁，其中69%为女性。MetS的患病率为30.5%。女性和男性的DPI平均得分分别为36.2±26.8和33.7±24.7。在完全调整模型中，男性（OR，1.57；95%CI，0.64 - 3.84）和女性（OR，0.86；95%CI，0.50 - 1.49）的DPI与MetS的几率之间均无显著关联。女性中，DPI与中心性肥胖风险增加呈负相关（OR，0.54；95%CI，0.29 - 1.00；p趋势 = 0.03）。男性和女性的DPI与MetS的其他组成部分之间均无显著关联。最后，我们观察到DPI与MetS的几率之间无显著关联。然而，这一发现表明，富含植物化学物质的饮食可能与腹部肥胖呈负相关。
