在智利，与体力活动无关，自我报告的久坐时间越高，患 2 型糖尿病的风险就越高。

Abstract

BACKGROUND

Sitting behaviours have increased markedly during the last two decades in Chile. However, their associations with health outcomes such as diabetes have not been reported. Therefore, the aim of this study was to investigate the independent association of self-reported sitting time with diabetes-related markers and diabetes prevalence in Chile.

METHODS

This cross-sectional study included participants (aged ≥18 years) from the Chilean National Health Survey 2009-10 (n = 4457). Fasting glucose and haemoglobin A1c (HbA1c) were measured by standardized protocols. The prevalence of type 2 diabetes (T2D) was determined using WHO criteria. Physical activity (PA) and time spent sitting were determined using the Global Physical Activity Questionnaire (GPAQ).

RESULTS

The odds ratio for T2D was 1.10 [95% CI: 1.04-1.16, P = 0.002] and 1.08 [1.02-1.14, P = 0.002] per 1 h increase in sitting time in men and women, respectively, independent of age, education, smoking, BMI and total PA. Overall, prevalence of T2D was 10.2 and 17.2% in individuals classified in the lowest and highest categories of sitting time, respectively. No significant associations were found between sitting time and glucose or HbA1c.

CONCLUSIONS

Sitting time is positively associated with diabetes risk, independent of socio-demographic, obesity and PA levels, in the Chilean population.

摘要

背景

在过去的二十年中，智利的久坐行为显著增加。然而，它们与糖尿病等健康结果的关系尚未得到报道。因此，本研究的目的是调查自我报告的久坐时间与糖尿病相关标志物和智利糖尿病患病率的独立关联。

方法

本横断面研究包括来自 2009-10 年智利国家健康调查的参与者（年龄≥18 岁，n=4457）。空腹血糖和糖化血红蛋白（HbA1c）通过标准化方案进行测量。使用世界卫生组织（WHO）标准确定 2 型糖尿病（T2D）的患病率。使用全球体力活动问卷（GPAQ）确定体力活动（PA）和久坐时间。

结果

男性和女性中，久坐时间每增加 1 小时，T2D 的比值比（OR）分别为 1.10（95%CI：1.04-1.16，P=0.002）和 1.08（1.02-1.14，P=0.002），分别独立于年龄、教育、吸烟、BMI 和总 PA。总体而言，久坐时间处于最低和最高分类的个体中 T2D 的患病率分别为 10.2%和 17.2%。久坐时间与血糖或 HbA1c 之间没有显著关联。
