In this study, we explored the associations among green space, ambient temperature, and air pollution from 2008 to 2021, with the aim to provide insights into the trends and relationships among built and natural environments factors and their impact on obesity in South Korean adults.
A total of 674,962 subjects from the Community Health Survey were analyzed. Descriptive statistics, Pearson correlation, and robust regression were used to help understand the changes in trend and the correlations between variables.
The mean age of the study subjects did not differ significantly based on body mass index (BMI); however, the obesity class 3 group had the lowest mean age. Exploration of green space and BMI showed a generally negative correlation in the normal weight group, but no such correlation was found in the overweight or obesity class 3 group. A positive correlation was observed between ambient temperature and BMI in the normal weight, overweight, and obesity class 1 groups. No strong association was found between air pollution and BM. While supporting evidence was found for the relationship between green space and ambient temperature, no such relationship was found between green space and air pollution. Lastly, air pollution and ambient temperature showed negative correlations, which contradicts the findings of prior studies.
Further exploration is needed to identify potential mechanisms and develop policies and neighborhood-level interventions aimed at addressing the built and natural environments factors contributing to obesity in urbanized settings.
The study design and data analysis protocol were reviewed and approved by the Institutional Review Board of the National Medical Center (IRB No. 202306069 IRB examination exemption approval 20230622).
在本研究中，我们探讨了2008年至2021年期间绿地、环境温度和空气污染之间的关联，旨在深入了解建筑和自然环境因素之间的趋势和关系及其对韩国成年人肥胖的影响。
对社区健康调查中的674,962名受试者进行了分析。使用描述性统计、Pearson相关性分析和稳健回归来帮助了解趋势变化以及变量之间的相关性。
研究对象的平均年龄在不同体重指数（BMI）组之间无显著差异；然而，3级肥胖组的平均年龄最低。对绿地和BMI的探索显示，在正常体重组中两者通常呈负相关，但在超重或3级肥胖组中未发现这种相关性。在正常体重、超重和1级肥胖组中，环境温度与BMI呈正相关。未发现空气污染与BMI之间存在强关联。虽然发现了绿地与环境温度之间关系的支持性证据，但未发现绿地与空气污染之间存在这种关系。最后，空气污染与环境温度呈负相关，这与先前研究的结果相矛盾。
需要进一步探索以确定潜在机制，并制定政策和社区层面的干预措施，以应对城市化环境中导致肥胖的建筑和自然环境因素。
