Research findings on the relationship between dietary resistant starch (RS) intake and metabolic diseases using population-based data are very scarce. This study examined the association of dietary RS intake with obesity and metabolic syndrome in Korean adults. A total of 12,491 adults (5292 men and 7199 women) were selected from the 2016-2018 Korea National Health and Nutrition Examination Survey data. The individual RS intake (g) was calculated by linking the 1-day 24 h recall data with the RS content database for common Korean foods. Obesity was defined as a BMI ≥ 25.0 kg/m. Metabolic syndrome was defined as having three or more of the following: abdominal obesity, elevated triglycerides, low HDL cholesterol, elevated fasting blood glucose, and elevated blood pressure. Odds ratios (ORs) with 95% confidence intervals (CIs) for obesity and metabolic syndrome across quartiles (Qs) of RS intake were calculated using multiple logistic regression analysis. In men, the highest quartile of RS intake showed a significantly lower OR for metabolic syndrome compared to the lowest quartile after adjusting for covariates (OR = 0.71, 95% CI = 0.56-0.92, -trend = 0.0057). Dietary RS intake in men was also inversely associated with obesity (Q4 vs. Q1: OR = 0.80, 95% CI = 0.67-0.97, -trend = 0.0329) and elevated triglycerides (Q4 vs. Q1: OR = 0.80, 95% CI = 0.66-0.98, -trend = 0.0314). In women, RS intake was not associated with metabolic syndrome. Our findings may serve as useful data for developing guidelines for RS intake and conducting further cohort and clinical studies to investigate the health effects of RS.
基于人群数据的膳食纤维（RS）摄入与代谢性疾病关系的研究结果非常有限。本研究旨在探讨韩国成年人膳食纤维摄入量与肥胖和代谢综合征的关系。本研究从 2016-2018 年韩国国家健康和营养调查数据中选取了 12491 名成年人（男性 5292 名，女性 7199 名）。通过将 1 天 24 小时回顾数据与常见韩国食品的 RS 含量数据库进行关联，计算个体 RS 摄入量（g）。肥胖定义为 BMI≥25.0kg/m。代谢综合征定义为具有以下三个或更多特征：腹部肥胖、甘油三酯升高、高密度脂蛋白胆固醇降低、空腹血糖升高和血压升高。采用多因素逻辑回归分析，计算 RS 摄入量四分位数（Qs）与肥胖和代谢综合征之间的比值比（OR）及其 95%置信区间（CI）。在男性中，调整协变量后，RS 摄入量最高四分位数与最低四分位数相比，代谢综合征的 OR 显著降低（OR=0.71，95%CI=0.56-0.92，-趋势=0.0057）。男性膳食纤维摄入量与肥胖（Q4 与 Q1：OR=0.80，95%CI=0.67-0.97，-趋势=0.0329）和甘油三酯升高（Q4 与 Q1：OR=0.80，95%CI=0.66-0.98，-趋势=0.0314）呈负相关。在女性中，RS 摄入量与代谢综合征无关。本研究结果可为制定 RS 摄入量指南以及开展进一步的队列和临床研究提供有用数据，以探讨 RS 的健康影响。
