To evaluate the association between total dietary fiber and its types and sources with the risk of MetS.
This population-based cross-sectional study was conducted on a representative sample of 2457 adults (1327 male and 1130 female), aged 19-84 years. Dietary intake was assessed using a validated semiquantitative food-frequency questionnaire. Anthropometrics, blood pressure, and fasting blood glucose and lipids were measured according to standard protocols. The MetS was defined according to definition by Adult Treatment Panel III.
Multivariate-adjusted odds ratio of MetS between highest and lowest quartiles was 0.53 (95% CI: 0.39-0.74; P for trend <0.05) for total dietary fiber, 0.60 (0.43-0.84; P for trend <0.05) for soluble fiber, and 0.51 (0.35-0.72; P for trend <0.05) for insoluble fiber. Among sources of dietary fiber, fruit fiber (OR: 0.51; 95% CI: 0.37-0.72), cereal fiber (0.74; 0.57-0.97), and legume fiber (0.73; 0.53-0.99) were inversely associated with the risk of MetS, after adjustment for confounding factors. Intake of vegetable fiber and nut fiber were unrelated to the risk of MetS.
Total dietary fiber, soluble- and insoluble fiber, fruit fiber, cereal fiber and legume fiber were associated with a protective effect for the presence of MetS among this Tehranian population.
评估总膳食纤维及其类型和来源与代谢综合征（MetS）风险之间的关系。
本研究为基于人群的横断面研究，纳入了 2457 名年龄在 19-84 岁的成年人（男性 1327 名，女性 1130 名）作为研究对象，采用经过验证的半定量食物频率问卷评估膳食摄入量。根据标准方案测量人体测量学、血压和空腹血糖及血脂。根据成人治疗小组 III 的定义来定义 MetS。
多变量调整后，膳食纤维摄入量最高和最低四分位数组之间 MetS 的比值比（OR）分别为 0.53（95%CI：0.39-0.74；P 趋势<0.05）、0.60（0.43-0.84；P 趋势<0.05）和 0.51（0.35-0.72；P 趋势<0.05）。在膳食纤维的来源中，水果纤维（OR：0.51；95%CI：0.37-0.72）、谷物纤维（0.74；0.57-0.97）和豆类纤维（0.73；0.53-0.99）与 MetS 风险呈负相关，在调整混杂因素后也是如此。蔬菜纤维和坚果纤维的摄入量与 MetS 风险无关。
在德黑兰人群中，总膳食纤维、可溶和不溶性膳食纤维、水果纤维、谷物纤维和豆类纤维与 MetS 的存在呈保护相关。
