In a group of 2,700 women making initial visits to the contraception clinic at one university (California State University at Fullerton) between 1974 and 1978, oral contraceptives were the most frequently chosen of three prescription methods. (The others were the IUD and diaphragm.) The proportion of women choosing the pill, however, declined sharply over the period--from 89 percent of patients in 1974 to 63 percent in 1978. Choice of the diaphragm rose substantially: In 1978, 33 percent chose it, compared to six percent in 1974. The proportion of women choosing the IUD fluctuated over the four-year period, showing no clear trend, and averaging eight percent over the entire span. The decline in the proportion of women choosing the pill was sharpest among white Anglo students--down from 85 percent to 63 percent; among nonwhites and Hispanics, the proportion fell from 89 percent to 80 percent. The increase in the choice of the diaphragm was also greatest among the Anglo students. These trends of decreased choice of the pill and increased acceptance of the diaphragm are much sharper than those shown among young married women at the national level.
在1974年至1978年间，一组2700名首次前往一所大学（加利福尼亚州立大学富勒顿分校）避孕诊所就诊的女性中，口服避孕药是三种处方避孕方法中最常被选择的。（另外两种是宫内节育器和子宫托。）然而，在此期间选择口服避孕药的女性比例急剧下降——从1974年的89%降至1978年的63%。选择子宫托的比例大幅上升：1978年，33%的女性选择了子宫托，而1974年这一比例为6%。选择宫内节育器的女性比例在这四年中波动不定，没有明显趋势，在整个时间段内平均为8%。选择口服避孕药的女性比例下降幅度最大的是英裔白人学生——从85%降至63%；在非白人和西班牙裔中，这一比例从89%降至80%。子宫托选择的增加在英裔学生中也最为显著。口服避孕药选择减少和子宫托接受度增加的这些趋势比全国范围内年轻已婚女性所显示的趋势更为明显。
