Recent work in a number of countries has identified growing geographical inequalities in health between deprived and non-deprived neighbourhoods. The health gaps observed cannot be entirely explained by differences in the characteristics of individuals living in those neighbourhoods, which has led to a concerted international public health research effort to determine what contextual features of neighbourhoods matter. This article reports on access to potentially health-promoting community resources across all neighbourhoods in New Zealand. Prevailing international opinion is that access to community resources is worse in deprived neighbourhoods.
Geographical Information Systems were used to calculate geographical access to 16 types of community resources (including recreational amenities, and shopping, educational and health facilities) in 38,350 small census areas across the country. The distribution of these access measures by neighbourhood socioeconomic deprivation was determined.
For 15 out of 16 measures of community resources, access was clearly better in more deprived neighbourhoods. For example, the travel time to large supermarkets was approximately 80% greater in the least deprived quintile of neighbourhoods compared with the most deprived quintile.
These results challenge the widely held, but largely untested, view that areas of high social disadvantage have poorer access to community resources. Poor locational access to community resources among deprived neighbourhoods in New Zealand does not appear to be an explanation of poorer health in these neighbourhoods. If anything, a pro-equity distribution of community resources may be preventing even wider disparities in neighbourhood inequalities in health.
一些国家最近的研究发现,贫困社区与非贫困社区之间的健康地理不平等现象日益加剧。观察到的健康差距不能完全由居住在这些社区的个体特征差异来解释,这促使国际公共卫生研究共同努力,以确定社区的哪些背景特征至关重要。本文报告了新西兰所有社区获取潜在促进健康的社区资源的情况。国际上普遍认为,贫困社区获取社区资源的情况更差。
利用地理信息系统计算全国38350个小普查区获取16种社区资源(包括娱乐设施、购物、教育和卫生设施)的地理可达性。确定了这些可达性指标按社区社会经济贫困程度的分布情况。
在16项社区资源指标中,有15项显示,贫困程度越高的社区,获取资源的情况明显更好。例如,与最贫困的五分位数社区相比,最不贫困的五分位数社区前往大型超市的出行时间大约多出80%。
这些结果挑战了一种广泛持有的但基本未经检验的观点,即社会劣势程度高的地区获取社区资源的情况更差。新西兰贫困社区在地理位置上获取社区资源的困难似乎并不能解释这些社区健康状况较差的原因。如果说有什么作用的话,社区资源的公平分配可能在防止社区健康不平等方面出现更大的差距。
