Mona Saraiya, M.D., from the CDC in Atlanta, and colleagues assessed trends in Pap testing using data from the Behavioral Risk Factor Surveillance System (BRFSS; 2000 to 2010) for 125,297 18- to 30-year-old women. The researchers found that, among women aged 18 to 21 years, there was an increase in the percentage reporting never having been tested (26.3 to 47.5 percent) and a decrease in the percentage reporting having had a Pap test in the past 12 months (from 65.0 to 41.5 percent). For women aged 22 to 30 years, the proportion never tested increased from 6.6 to 9.0 percent, and the proportion who had a Pap test in the previous year decreased from 78.1 to 67.0 percent.In a second study, Meg Watson, M.P.H., also from the CDC, and colleagues assessed recent screening behaviors and trends using data from the BRFSS for women aged 30 years and older. The researchers noted a decrease in the proportion of women reporting having had a hysterectomy who had undergone a recent Pap test (within three years), from 73.3 percent in 2000 to 58.7 percent in 2010. These decreases were consistent among women aged 30 to 64 years, for women aged 65 and older, and for women aged 65 years and older with no history of hysterectomy.
