It has commonly been suggested (including by this author) that individual or household deprivation (for example, low income) is amplified by area level deprivation (for example, lack of affordable nutritious food or facilities for physical activity in the neighbourhood).
The idea of deprivation amplification has some intuitive attractiveness and helps divert attention away from purely individual determinants of diet and physical activity, and towards health promoting or health damaging features of the physical and social environment. Such environmental features may be modifiable, and environmental changes may help promote healthier behaviors. However, recent empirical examination of the distribution of facilities and resources shows that location does not always disadvantage poorer neighbourhoods. This suggests that we need: a) to ensure that theories and policies are based on up-to-date empirical evidence on the socio-economic distribution of neighbourhood resources, and b) to engage in further research on the relative importance of, and interactions between, individual and environmental factors in shaping behavior.
In this debate paper I suggest that it may not always be true that poorer neighbourhoods are more likely to lack health promoting resources, and to be exposed to more health damaging resources. The spatial distribution of environmental resources by area socioeconomic status may vary between types of resource, countries, and time periods. It may also be that the presence or absence of resources is less important than their quality, their social meaning, or local perceptions of their accessibility and relevance.
有人(包括作者本人)提出,个体或家庭贫困(例如收入低)会因地区贫困(例如,附近缺乏负担得起的营养食品或体育活动设施)而加剧。
贫困加剧的观点具有一定的直观吸引力,有助于将注意力从饮食和体育活动的纯粹个体决定因素上转移开,转向促进健康或损害健康的物理和社会环境特征。这些环境特征可能是可以改变的,环境变化可能有助于促进更健康的行为。然而,最近对设施和资源分布的实证研究表明,位置并不总是使较贫困的社区处于不利地位。这表明我们需要:a)确保理论和政策以关于邻里资源的社会经济分布的最新实证证据为基础,b)进一步研究个体和环境因素在塑造行为方面的相对重要性和相互作用。
在这篇辩论文章中,我认为,贫困社区更有可能缺乏促进健康的资源,并面临更多损害健康的资源,这并不总是正确的。按地区社会经济地位划分的环境资源的空间分布可能因资源类型、国家和时间而有所不同。资源的存在与否可能不如其质量、社会意义或当地对其可及性和相关性的看法重要。
