High-Rise Residential Outdoor Space Value System: A Case Study of Yangtze River Delta Area

Association between perceived neighborhood environment and depression among residents living in mega-communities in Guiyang, China: a cross-sectional study

BACKGROUND

Little was known about the relationship between perceived neighborhood environment and depression among residents living in mega-communities. Furthermore, the mediating effects of physical activity (PA) and anxiety in this relationship have not been investigated. Thus, this study aimed to comprehensively examine the association between perceived neighborhood environment and depression among residents living in mega-communities, and test whether PA and anxiety mediated the association.

METHODS

A cross-sectional study on perceived neighborhood environment and depression was conducted among individuals who lived in mega-communities (n = 665) in Guiyang, China from July to August 2022. Perceived neighborhood environment was assessed from the following six aspects: traffic, building quality, accessibility, neighborhood, indoor, and pollution. Depression was measured by the Patients Health Questionnaire-9. Structural equation model was used to evaluate the association between perceived neighborhood environment and depression, and test the mediating effect of PA and anxiety in this association.

RESULTS

We found that neighborhood (β = -0.144, p = 0.002) and PA (β = -0.074, p < 0.001) were both negatively associated with depression, while anxiety was positively associated with depression (β = 0.447, p < 0.001). Married residents were less likely to experience depression than residents of other marital status. PA played a mediator role in the relationship between accessibility and depression (β = 0.014, p = 0.033). PA mediated the relationship between neighborhood and depression (β = -0.032, p = 0.015). The mediating effect of anxiety in the relationship between perceived neighborhood environment and depression was not significant.

CONCLUSIONS

This study demonstrated that neighborhood, which was assessed by satisfaction with safety, hygiene, parking, greening, lighting, and building shape, was negatively associated with depression, and PA mediated the relationship.

Characterization of soundscape assessment in outdoor public spaces of urban high-rise residential communitiesa)

Soundscape perceptual models were developed in various contexts. However, as the outdoor public space in high-rise residential communities differs in terms of space planning and management, the soundscape perceptual characteristics are still unclear. In this study, an on-site survey was conducted to obtain the perceptual dimensions of soundscape in outdoor public spaces in urban high-rise residential communities based on evaluations of residents. Meantime, the soundscape of the space in different community layouts were compared. It was found that: (1) Four dimensions of outdoor soundscape in high-rise communities were extracted, namely Relaxation, Communication, Quietness, and Spatiality. The first three dimensions were positively correlated with overall soundscape satisfaction significantly. (2) Relaxation was mostly correlated with dominance of noise; Communication and Quietness were primarily related to sounds from human beings. (3) Lower traffic noise and higher levels of human sounds were perceived in enclosed communities, resulting in higher Relaxation and lower Quietness scores in outdoor public spaces in enclosed communities than non-enclosed ones. These findings evoke insights into the understanding of soundscape assessment in different contexts, and provide implications for sound environment design in urban high-rise communities.
