■虽然大量蔬菜的摄入与便秘风险的降低有关,尤其是哪些蔬菜是这种降低风险的基础,目前尚不完全清楚。因此,本研究旨在探讨特定蔬菜类型的摄入量与便秘风险之间的相关性。
■此横截面分析基于2005-2010年收集的国家健康与营养检查调查(NHANES)的数据。用食物模式等同数据库(FPED)评估不同蔬菜的分类和摄入量评估,而大便频率或大便稠度用于定义便秘。通过加权逻辑回归方法评估了特定蔬菜成分的摄入量与便秘之间的关系。亚组和限制性三次样条(RCS)回归分析进一步用于探索特定蔬菜亚型与便秘之间的关联。
■这项研究包括13,860名符合条件的受试者,其中1,405和12,455人分别分为便秘和非便秘组。在多变量调整之后,包括橙子在内的非淀粉类蔬菜的摄入量,红色,深绿色,和其他蔬菜被发现与便秘风险的降低呈正相关。相比之下,便秘与淀粉蔬菜或马铃薯的总摄入量无关。西红柿,特别是,与便秘风险显著降低相关(比值比:0.80,95%置信区间:0.71-0.91)。这些结果通过RCS和亚组分析得到证实。
■非淀粉蔬菜,尤其是西红柿,被发现与便秘风险的显著降低有关,不受土豆或淀粉蔬菜摄入的影响。
UNASSIGNED: While the intake of larger quantities of vegetables has been linked to a reduction in constipation risk, which vegetables in particular underlie this risk reduction remains incompletely understood. As such, the present study was developed to explore correlations between the intake of particular vegetable types and the risk of constipation.
UNASSIGNED: This cross-sectional analysis was based on data from the National Health and Nutrition Examination Survey (NHANES) collected from 2005-2010. Classifications and intake assessments for different vegetables were assessed with the Food Patterns Equivalents Database (FPED), while stool frequency or stool consistency was used to define constipation. Relationships between the intake of particular vegetable components and constipation were assessed through a weighted logistic regression approach. Subgroup and restricted cubic spline (RCS) regression analyses were further employed to explore associations between specific vegetable subtypes and constipation.
UNASSIGNED: This study included 13,860 eligible subjects, of whom 1,405 and 12,455 were respectively classified into the constipated and non-constipated groups. Following multivariate adjustment, the intake of non-starchy vegetables including orange, red, dark green, and other vegetables was found to be positively associated with a reduction in constipation risk. In contrast, constipation was unrelated to total starchy vegetable or potato intake.
Tomatoes, in particular, were associated with a marked decrease in constipation risk (odds ratios: 0.80, 95% confidence interval: 0.71-0.91). These results were confirmed through RCS and subgroup analyses.
UNASSIGNED: Non-starchy vegetables, particularly
tomatoes, were found to be associated with a pronounced reduction in constipation risk, which was unaffected by the intake of potatoes or starchy vegetables.
