Outdoor Space Elements in Urban Residential Areas in Shenzhen, China: Optimization Based on Health-Promoting Behaviours of Older People

Abstract

Given the ageing global population, it is important to promote “healthy ageing”. One of the most effective ways to achieve this is by prolonging the health of older people. Both the physical and mental well-being of older people are closely related to their living environment. Providing daily outdoor activities and enhancing the quality of public spaces and amenities in residential areas can encourage the adoption of healthy behaviours among older people. This study selected eight typical residential areas in Shenzhen, China, and analysed 40 outdoor public spaces. Video content obtained from fixed-point behavioural observation was entered into the Mangold INTERACT behavioural analysis system to extract the health behaviour data of older people. Regression analysis was then performed on the health behaviour data and the index data of the sample space elements. The results showed that several factors affect the outdoor health behaviours of older people. These factors include the scale of the outdoor space, the size of the hard ground area, the quality of the grey space, the green-looking rate, the accessibility of the site, the number of fitness facilities, and the richness of site functions. This study focused on a host of health-related behaviours such as rest, leisure, communication, and exercise. It confirmed the corresponding spatial needs of the elderly when engaging in the aforesaid activities. In this way, the quantitative research has supplemented previous studies by studying and evaluating the behaviour and activities of the elderly in specific settings. Through the analyses, a configuration model of outdoor space in residential areas was constructed with the aim of health promotion. Based on this model, a flexible and multilevel configuration list revealing seven specific types under three priorities is being proposed. The findings provide a scientific and effective strategy for optimising the quality of outdoor environments in residential areas. More specifically, the deployment of the Mangold INTERACT system to extract and quantify behavioural data enabled this study to overcome the limitations of traditional approaches to behavioural observation and recording. This provides a prelude for other quantitative research on the environment and behaviour.
