In 1999, the UK Government launched a strategy to reduce teenage pregnancy and geographical inequalities in teenage conception rates. This study investigates how associations between deprivation and under-18 conceptions, along with subsequent abortions, since changed as teenage pregnancy rates fell.
A data set was constructed from local authority Indices of Multiple Deprivation (IMD) scores and routine data on under-18 conception rates and the proportion of under-18 conceptions leading to abortion from 1998 to 2010. Correlation analysis (Pearson's r) was used to measure the association between each period of conception and abortion data and the relevant version of the IMD. Changes in these correlations over the period were tested for statistical significance.
There remained a strong association between IMD and under-18 conception rates from 1998 (r = 0.782, P< 0.0001) to 2010 (r = 0.817, P< 0.0001) with no statistically significant change. A statistically significant decrease occurred in the inverse association between IMD and the proportion of under-18 conceptions leading to abortion from 1998 (r = -0.501, P< 0.0001) to 2010 (r = -0.332, P< 0.0001)
While under-18 conceptions fell from 1998 to 2010, inequalities in rates between the most and least deprived local authorities remained undiminished. At the same time, abortion became an increasingly common outcome of under-18 conceptions.
1999 年,英国政府启动了一项战略,旨在降低青少年怀孕率和减少青少年妊娠率的地域不平等。本研究调查了自青少年怀孕率下降以来,贫困程度与 18 岁以下妊娠率以及随后的堕胎率之间的关联如何发生变化。
从地方当局的综合贫困指数(IMD)得分以及 1998 年至 2010 年期间 18 岁以下妊娠率和 18 岁以下妊娠导致堕胎的比例的常规数据中构建了一个数据集。使用相关分析(Pearson r)来衡量每个妊娠和堕胎数据与相关 IMD 版本之间的关联。测试了该期间这些相关性变化的统计学意义。
1998 年至 2010 年,IMD 与 18 岁以下妊娠率之间仍存在很强的关联(r = 0.782,P<0.0001),且无统计学意义的变化。IMD 与 18 岁以下妊娠导致堕胎的比例之间的反向关联在 1998 年(r = -0.501,P<0.0001)至 2010 年(r = -0.332,P<0.0001)期间显著下降。
虽然 18 岁以下妊娠率从 1998 年降至 2010 年,但最贫困和最富裕地方当局之间的比率不平等仍未减少。与此同时,堕胎成为 18 岁以下妊娠的一个越来越常见的后果。
