Although the association between poor health and deprivation is well-founded, a 'Scottish effect' has been observed, whereby the level of health appears even poorer than Scotland's higher level of deprivation should warrant. We consider whether 'Scottish effects' also occur within the regions of England and Wales.
Using ward-level data from the national census, we regress healthy life expectancies relative to total life expectancies on Carstairs deprivation scores, households' average disposable incomes, geo-spatial characteristics and regional dummy variables.
Higher incomes and lower Carstairs scores are each associated with longer proportions of lives expected to be spent in good health or without long-standing illness. Relative to the London region, the coefficients on the regional dummies are uniformly negative and mostly significant.
There exist differences in relative health expectancies between the regions of England and Wales, which are not fully explained by the differences in socio-economic circumstances. Conventional deprivation measures tend to understate the poorer health performances of the more deprived regions (Wales and the north of England), and the understatement increases with deprivation. The exception to the rule is London, where health expectancies are superior to those which deprivation leads us to expect.
尽管健康状况不佳与贫困之间的关联是有充分依据的,但人们观察到一种“苏格兰效应”,即健康水平似乎比苏格兰较高的贫困水平所应有的更差。我们探讨“苏格兰效应”是否也在英格兰和威尔士的地区内出现。
利用全国人口普查的病房层面数据,我们将健康预期寿命相对于总预期寿命对卡斯尔斯贫困得分、家庭平均可支配收入、地理空间特征和地区虚拟变量进行回归。
较高的收入和较低的卡斯尔斯得分均与预期健康状况良好或无长期疾病的生命比例较长相关。相对于伦敦地区,地区虚拟变量的系数均为负且大多显著。
英格兰和威尔士各地区之间的相对健康预期存在差异,社会经济状况的差异并不能完全解释这些差异。传统的贫困衡量方法往往低估了贫困程度较高地区(威尔士和英格兰北部)较差的健康表现,且这种低估随着贫困程度的增加而加大。唯一的例外是伦敦,其健康预期优于贫困状况使我们预期的水平。
