Spatial analysis of falls in an urban community of Hong Kong.

Lai PC, Low CT, Wong M, Wong WC, Chan MH - Int J Health Geogr (2009)

Bottom Line: The results affirm the multi-factorial nature of falls at specific locations and for selected groups of the population.The combined use of descriptive and spatial analyses can be beneficial to policy makers because different preventive measures can be devised based on the types of environmental risk factors identified.The analyses are also important preludes to establishing research hypotheses for more focused studies.

ABSTRACT

Background: Falls are an issue of great public health concern. This study focuses on outdoor falls within an urban community in Hong Kong. Urban environmental hazards are often place-specific and dependent upon the built features, landscape characteristics, and habitual activities. Therefore, falls must be examined with respect to local situations.

Results: This paper uses spatial analysis methods to map fall occurrences and examine possible environmental attributes of falls in an urban community of Hong Kong. The Nearest neighbour hierarchical (Nnh) and Standard Deviational Ellipse (SDE) techniques can offer additional insights about the circumstances and environmental factors that contribute to falls. The results affirm the multi-factorial nature of falls at specific locations and for selected groups of the population.

Conclusion: The techniques to detect hot spots of falls yield meaningful results that enable the identification of high risk locations. The combined use of descriptive and spatial analyses can be beneficial to policy makers because different preventive measures can be devised based on the types of environmental risk factors identified. The analyses are also important preludes to establishing research hypotheses for more focused studies.

Figure 1: Fall locations in Mong Kok, Hong Kong, 2006–07.

Mentions: The study area of this research is Mong Kok, an urban community covering an area approximately of 268.2 hectares in the Yau Tsim Mong District (Figure 1). Mong Kok is one of the most crowded communities in Hong Kong and had a population density of 40,136 persons per square kilometer in 2006 [27]. With its substantial commercial and retail activities, the peak time pedestrian flow of Mong Kok in 2007 reached 25,000 persons per hour [28]. The overwhelmingly crowded streets and sidewalks mean inadequate space for pedestrian movements and an increased risk of fall.
