To examine the spatial patterning of the individuals with gonorrhea or chlamydia infection in the Calgary Health Region (CHR) to target prevention and control activities.
A Geographic Information System was used to map the prevalence rates of gonorrhea and chlamydia infection in the CHR to 2001 Census Tracts in the CHR. Data from the 2001 Canadian Census were used to describe the socioeconomic status (SES) of these areas.
Low SES indicators correlated with each other (low median household income, lower education, single mothers) as did high SES indicators (married, owning a dwelling, high median income, university education). A correlation was detected between areas of low SES and areas of high prevalence rates for gonorrhea and for chlamydia. These areas clustered primarily downtown and in the northeast part of the city.
Nodes and corridors of activity in Calgary were detected in correlation studies of the 2001 Census variables used. The core (high prevalence) areas should be the areas targeted for sexually transmitted infection prevention and control. This can be done at the community level through measures such as more sexually transmitted infection clinics operating with longer hours in areas identified from this mapping.
研究卡尔加里健康区（CHR）淋病或衣原体感染个体的空间分布模式，以便确定预防和控制活动的目标。
利用地理信息系统将CHR淋病和衣原体感染患病率映射到CHR的2001年人口普查区。2001年加拿大人口普查数据用于描述这些地区的社会经济地位（SES）。
低SES指标相互关联（家庭收入中位数低、教育程度低、单身母亲），高SES指标也相互关联（已婚、拥有住房、收入中位数高、大学教育）。在低SES地区与淋病和衣原体高患病率地区之间发现了相关性。这些地区主要集中在市中心和城市东北部。
在对所使用的2001年人口普查变量进行的相关性研究中，检测到了卡尔加里的活动节点和走廊。核心（高患病率）地区应成为性传播感染预防和控制的目标地区。这可以在社区层面通过诸如在根据此地图确定的地区开设更多营业时间更长的性传播感染诊所等措施来实现。
