To compare breast cancer screening rates from the 1991 survey with data from 1987-88 for women aged 65 to 74.
Surveys of women from five communities.
Five control communities of the National Cancer Institute's Breast Cancer Screening Consortium.
White, non-Hispanic women, ages 65 to 74; 499 in 1987-88 and 2156 in 1991. Response rates for the first survey wave ranged by area from 65% to 77% and for the second survey wave, from 62% to 85%.
Mammogram and clinical breast examination during the past year and performance of monthly breast self examination, with the screening rates in wave 2 directly standardized to the income and education distribution of wave 1 in each area.
Mammography use between waves increased significantly (P < 0.05 after adjusting for education, income, and age) in all but one area (from 19% to 33% in wave 1 to 35% to 59% in wave 2). Among women who had a mammogram, the percent who also had a clinical breast examination decreased between waves from 95% to 85% (P = 0.001).
Mammography in older women increased dramatically over 3 years, although the use of clinical breast examination may be decreasing.
比较1991年调查中65至74岁女性的乳腺癌筛查率与1987 - 1988年的数据。
对来自五个社区的女性进行调查。
国家癌症研究所乳腺癌筛查联盟的五个对照社区。
65至74岁的非西班牙裔白人女性；1987 - 1988年有499人，1991年有2156人。第一轮调查的回复率因地区而异，从65%至77%不等，第二轮调查的回复率从62%至85%不等。
过去一年中的乳房X光检查和临床乳房检查以及每月乳房自我检查的情况，第二轮调查的筛查率直接根据各地区第一轮调查的收入和教育分布进行标准化。
除一个地区外，各轮调查之间乳房X光检查的使用率显著增加（在调整教育、收入和年龄后P < 0.05）（从第一轮的19%增至33%，到第二轮的35%至59%）。在进行了乳房X光检查的女性中，同时进行临床乳房检查的女性比例在两轮调查之间从95%降至85%（P = 0.001）。
在3年时间里，老年女性的乳房X光检查使用率大幅上升，尽管临床乳房检查的使用率可能在下降。
