Socioeconomic inequalities in cancer mortality in Britain have been shown to be present in the 1990s and early 2000s. Little is known about on-going patterns in such inequalities in cancer mortality. We examined time trends in socioeconomic inequalities in cancer mortality in Britain between 1978 and 2013.
A socially representative cohort of 7489 British men with data on longest-held occupational social class, followed up for 35 years, in whom 1484 cancer deaths occurred.
The hazard ratio for cancer mortality for manual vs. non-manual social classes remained unchanged; among men aged 50-59 years it was 1.62 (95%CI 1.17-2.24) between 1980-1990 and 1.65 (95%CI 1.14-2.40) between 1990-2000. The absolute difference (non-manual minus manual) in probability of surviving death from cancer to 70 years remained at 3% over the follow-up. The consistency of risks over time was similar for both smoking-related and non-smoking related cancer mortality.
Socioeconomic inequalities in cancer mortality in Britain remain unchanged over the last 35 years and need to be urgently addressed.
有证据表明,20世纪90年代和21世纪初英国癌症死亡率存在社会经济不平等现象。对于此类癌症死亡率不平等现象的持续模式,人们知之甚少。我们研究了1978年至2013年间英国癌症死亡率社会经济不平等的时间趋势。
对7489名英国男性进行具有社会代表性的队列研究,这些男性拥有其长期从事职业的社会阶层数据,随访35年,其中有1484例癌症死亡病例。
体力劳动者与非体力劳动者社会阶层的癌症死亡率风险比保持不变;在50 - 59岁男性中,1980 - 1990年间为1.62(95%置信区间1.17 - 2.24),1990 - 2000年间为1.65(95%置信区间1.14 - 2.40)。在随访期间,癌症死亡后存活至70岁的概率的绝对差异(非体力劳动者减去体力劳动者)保持在3%。吸烟相关和非吸烟相关癌症死亡率随时间的风险一致性相似。
在过去35年中,英国癌症死亡率的社会经济不平等状况保持不变,亟待解决。
