Research on the relationship between metabolic syndrome (MetS), its components and eating speed is limited in China. The present study aimed to clarify the association between MetS, its components and eating speed in a Beijing adult population.
This cross-sectional study included 7972 adults who were 18-65 years old and who received health check-ups at the Beijing Physical Examination Center in 2016. Logistic regression was conducted to explore the associations between MetS, its components and eating speed.
The prevalence of MetS in this population was 24.65% (36.02% for males and 10.18% for females). Eating speed was significantly associated with a high risk for MetS, elevated blood pressure, and central obesity for both genders. Eating speed was associated with a high risk for elevated triglycerides and with a reduction in high-density lipoprotein in males, and eating speed was associated with a high risk for elevated fasting plasma glucose in females. Compared with slow eating speed, the multivariate-adjusted odds ratios of medium eating speed and fast eating speed for MetS were 1.65 (95% confidence interval 1.32-2.07) and 2.27 (95% confidence interval 1.80-2.86) for all subjects, 1.58 (95% confidence interval 1.21-2.07) and 2.21 (95% confidence interval 1.69-2.91) for males, and 1.75 (95% confidence interval 1.15-2.68) and 2.27 (95% confidence interval 1.46-3.53) for females, respectively.
Eating speed is positively associated with MetS and its components. Future recommendations aiming to prevent MetS and its components may focus on eating speed.
代谢综合征（MetS）及其各组分与进食速度之间的关系的研究在中国较为有限。本研究旨在明确北京成年人群中 MetS 及其各组分与进食速度之间的关系。
这是一项横断面研究，纳入了 2016 年在北京体检中心接受健康检查的 7972 名 18-65 岁成年人。采用 logistic 回归分析探讨 MetS 及其各组分与进食速度之间的关联。
该人群中 MetS 的患病率为 24.65%（男性为 36.02%，女性为 10.18%）。进食速度与 MetS、高血压和中心性肥胖的风险升高均显著相关，且无论男女均如此。进食速度与男性的甘油三酯升高风险升高和高密度脂蛋白降低相关，与女性的空腹血糖升高风险升高相关。与慢速进食相比，所有人群中中速和快速进食的 MetS 多变量校正比值比分别为 1.65（95%置信区间 1.32-2.07）和 2.27（95%置信区间 1.80-2.86），男性分别为 1.58（95%置信区间 1.21-2.07）和 2.21（95%置信区间 1.69-2.91），女性分别为 1.75（95%置信区间 1.15-2.68）和 2.27（95%置信区间 1.46-3.53）。
进食速度与 MetS 及其各组分呈正相关。未来预防 MetS 及其各组分的建议可能需要关注进食速度。
