Although evidence on the health effects of sedentary behavior (SB) has grown systematically in recent years, few developing countries have reported population levels of SB, especially in South America. Our objective was to describe time spent sitting in a representative sample from Chile categorized by age, gender, educational level, and body mass index (BMI).
A national health survey was conducted in Chile in a nationally representative sample ( = 5411) in 2009-2010. Sitting time (ST) was measured with the Global Physical Activity Questionnaire Version 2.
Data were from 5031 participants (43.26 ± 0.41 years, mean ± SE; 40.3% male). Overall, there were no gender differences in mean ST (men: 158.10 ± 5.80 min/day, women 143.45 ± 4.77 min/day; = 0.05). ST was lower in those who lived in rural areas compared with urban areas (99.4 min/day 160.0 min/day; = 0.001). ST increased significantly with increasing BMI, but only in men ( = 0.009), and was positively related to years of education in both men and women ( < 0.0001).
The findings were different from those reported in other countries and contexts, reinforcing the need for international surveillance and monitoring over time to inform policy makers. Differences in ST across different groups emphasize the need to develop tailored messages and interventions for reducing ST in different population subgroups.
尽管近年来关于久坐行为（SB）对健康影响的证据在系统增加，但很少有发展中国家报告过久坐行为的人群水平，尤其是在南美洲。我们的目标是描述智利一个具有代表性样本中按年龄、性别、教育水平和体重指数（BMI）分类的久坐时间。
2009 - 2010年在智利对一个具有全国代表性的样本（n = 5411）进行了一项全国性健康调查。使用全球身体活动问卷第2版测量久坐时间（ST）。
数据来自5031名参与者（平均年龄43.26 ± 0.41岁，均值 ± 标准误；男性占40.3%）。总体而言，平均久坐时间不存在性别差异（男性：158.10 ± 5.80分钟/天，女性143.45 ± 4.77分钟/天；P = 0.05）。与城市地区居民相比，农村地区居民的久坐时间较短（99.4分钟/天对160.0分钟/天；P = 0.001）。久坐时间随BMI增加而显著增加，但仅在男性中如此（P = 0.009），并且在男性和女性中均与受教育年限呈正相关（P < 0.0001）。
这些发现与其他国家和背景下报告的结果不同，这进一步强调了需要进行长期的国际监测，以便为政策制定者提供信息。不同群体之间久坐时间的差异强调了需要针对不同人群亚组制定有针对性的信息和干预措施以减少久坐时间。
