AbstractHeroin addiction is a socio-behavioral and medical condition with significant public health implications. It is known that socioeconomic factors and population changes are important forces shaping the pattern of heroin addiction in a community. An understanding of these factors would be useful for the planning of effective intervention strategies. We applied the GIS technology in a study to display heroin addiction data over consecutive years in 18 districts of the territory of Hong Kong. Correlation was made between the proportions of heroin users in each district with the following variables: (a) changes in the local population size and structure; (b) economic attributes, in terms of employment and household income; (c) social factors, notably education levels; and (d) access to drug rehabilitation services, using methadone clinics as the surrogates. The data were obtained from available repository including the Census data, service statistics of methadone clinics, and Central Registry of Drug Abuse. The spatiotemporal framework has enabled analyses from different perspectives. We concluded that despite an overall decline in the number of heroin users in Hong Kong over the years, proportional increases were observed in selected districts. The association with poorer socioeconomic indices was obvious and the coverage of methadone clinics was found to vary from one district to another. The study offered a new means for examining conventional data, which may be useful in fostering public health policy development in the long run.
