Abstract

OBJECTIVES

This study examined trends in breast cancer mortality by education, age, and birth cohort.

METHODS

Census records of Finnish women 35 years and older were linked with death records for 1971 through 1995.

RESULTS

Excess breast cancer mortality of more-educated women has declined rapidly, mainly because of increasing mortality among less-educated women and stable or decreasing mortality among more-educated 35- to 64-year-old women. During the 1990s, mortality among more-educated 50- to 64-year-old women declined particularly fast.

CONCLUSIONS

The causes of declining differences by education in breast cancer mortality are difficult to verify, but they may be due in part to narrowing differences in reproductive behavior among the younger birth cohorts and to a period effect possibly associated with the introduction of breast cancer screening in the late 1980s.

摘要

目的

本研究探讨了按教育程度、年龄和出生队列划分的乳腺癌死亡率趋势。

方法

将芬兰35岁及以上女性的人口普查记录与1971年至1995年的死亡记录相链接。

结果

受教育程度较高女性的乳腺癌超额死亡率迅速下降,主要原因是受教育程度较低女性的死亡率上升,以及受教育程度较高的35至64岁女性的死亡率稳定或下降。在20世纪90年代,受教育程度较高的50至64岁女性的死亡率下降尤为迅速。

结论

乳腺癌死亡率按教育程度划分的差异下降的原因难以核实,但可能部分归因于较年轻出生队列生殖行为差异的缩小,以及可能与20世纪80年代末引入乳腺癌筛查相关的时期效应。
