(1) : Environment is an independent factor that affects one's quality of life (QoL), where studies suggest that health behaviours also affect one's quality of life. The purpose of the present study was to examine the association between environmental conditions and QoL and how individual health behaviours affect this association. (2) : Participants aged 20 or above were recruited from 11 tertiary planning units in the central part of Kowloon. These tertiary planning units were selected as they represented the overall living environment in Hong Kong, with a mix of the poorer urban areas alongside relatively affluent districts. A mediation analysis was implemented using multiple linear regressions to examine the effects of environmental conditions on QoL. (3) : Of the 607 eligible participants included for analysis, 390 were female and 217 were male, with a mean age of 47.4 years. Living within 500 m of a green space area had benefits on the physical aspect of QoL and physical activity but no effect on the psychological aspect of QoL. Moderate satisfaction with public spaces affected QoL positively. In contrast, less satisfaction with public spaces affected QoL negatively in both physical and psychological aspects through the mediating effect of stress. Poor environmental quality affected all domains of QoL negatively through the mediating effects of increased stress and poor sleep. (4) : Environment is an important factor that affects individuals' overall well-being. The interaction between environmental conditions and individual variables, especially perceived stress and sleep, is extremely important when assessing its impact on QoL. The findings of this study support the importance of individual stress and sleep in mediating the relationship between the environment and QoL for health. Further studies should be conducted to include objective measurements, such as those of cortisol levels for stress and physical fitness tests.
(1) 环境是影响生活质量（QoL）的独立因素，有研究表明健康行为也会影响生活质量。本研究旨在探讨环境条件与生活质量之间的关系，以及个体健康行为如何影响这种关系。
(2) 参与者年龄在 20 岁或以上，从九龙中部的 11 个三级规划单位招募。选择这些三级规划单位是因为它们代表了香港的整体生活环境，既有较贫困的市区，也有相对富裕的地区。采用多元线性回归进行中介分析，以检验环境条件对生活质量的影响。
(3) 在纳入分析的 607 名合格参与者中，390 名为女性，217 名为男性，平均年龄为 47.4 岁。居住在距离绿地 500 米范围内对生活质量的身体方面和身体活动有好处，但对心理方面没有影响。对公共空间的适度满意度对生活质量有积极影响。相反，对公共空间的满意度较低会通过压力的中介作用对生活质量的身体和心理方面产生负面影响。较差的环境质量会通过增加的压力和较差的睡眠的中介作用对生活质量的所有方面产生负面影响。
(4) 环境是影响个体整体幸福感的重要因素。在评估环境对生活质量的影响时，环境条件与个体变量之间的相互作用，特别是感知压力和睡眠，极其重要。本研究的结果支持了个体压力和睡眠在调节环境与生活质量之间关系对健康的重要性。应进一步开展研究，包括对压力的皮质醇水平和身体适应性测试等客观测量。
