This study examines the relationship between distance to green space and the level of physical activity among the population of Denmark. In addition, the relationship between distance to green space and obesity is investigated.
Data derived from the Danish National Health Interview Survey 2005, a cross-sectional survey based on a region-stratified random nationally representative sample of 21,832 Danish adults. All data are self-reported.
Respondents living more than 1 km from green space had lower odds of using green space to exercise and keep in shape compared with persons living closer than 300 m to green space (OR: 0.71; 95% CI: 0.60-0.83). A relationship between moderate/vigorous physical activity during leisure time and distance to green space can also be found. Persons living more than 1 km from green space had higher odds of being obese (BMI ≥ 30) than those living less than 300 m from green space (OR: 1.36; 95% CI: 1.08-1.71).
Self-reported distance to green space is related to self-reported physical activity and obesity. To exercise and keep in shape is an important reason for visiting green space, and distance to green space is associated with moderate/vigorous physical activity in leisure time.
本研究考察了丹麦人群中绿地距离与身体活动水平之间的关系。此外，还调查了绿地距离与肥胖之间的关系。
数据来自 2005 年丹麦全国健康访谈调查，这是一项基于区域分层随机全国代表性样本的横断面调查，涵盖了 21832 名丹麦成年人。所有数据均为自我报告。
与居住在距离绿地 300 米以内的人相比，居住在距离绿地 1 公里以上的人使用绿地进行锻炼和保持身材的可能性较低（OR：0.71；95%CI：0.60-0.83）。在休闲时间进行中等到剧烈身体活动与距离绿地之间也存在关系。居住在距离绿地 1 公里以上的人肥胖（BMI≥30）的几率高于居住在距离绿地 300 米以内的人（OR：1.36；95%CI：1.08-1.71）。
自我报告的绿地距离与自我报告的身体活动和肥胖有关。进行锻炼和保持身材是访问绿地的一个重要原因，而绿地距离与休闲时间的中等到剧烈身体活动有关。
