STATISTICAL BRIEF #173
June 2007
Use of the Pap Test as a Cancer
Screening Tool among Women Age 18
64, U.S. Noninstitutionalized
Population, 2005
Anita Soni, PhD
Introduction
The main purpose of the Pap test (also called the Pap smear test) is
to detect cancer or abnormal cells that may lead to cancer. It can
also find non-cancerous conditions, such as infection and inflam-
mation. Cervical cancer can usually be prevented if women are
screened regularly with a Pap test. The U.S. Preventive Services
Task Force (USPSTF) found evidence that cervical cytology (Pap
smear) screening reduces the incidence of and mortality from
cervical cancer. The USPSTF suggests Pap smear screening at
least every three years for women age 1864.
This Statistical Brief provides estimates of the extent to which
women age 1864 did not receive Pap smear screening for cervical
cancer detection in 2005. The estimates presented are derived from
data collected in the MEPS Household Component questionnaire. All
differences discussed in the text are statistically significant at 0.05 or
better.
Findings
Evidence has been found that screening with cervical cytology (Pap
smear) reduces the incidence of and mortality from cervical cancer.
The Pap test every three years has been recommended for all
women age 1864. In 2005, approximately 13 million women age
1864 reported not having received the Pap test within the last three years.
Highlights
Almost 14 percent of
women age 1864 reported
not having received a Pap
smear test within the last
three years.
Asian non-Hispanic women
were least likely to have
received the Pap test within
the last three years as
compared with Hispanic,
white non-Hispanic, or
black non-Hispanic women.
One-fourth of women who
were uninsured failed to
receive the Pap test within
the last three years.
Women who were less
educated were more likely
not to have received the
Pap test within the last
three years.
Single (never married)
women were nearly twice
as likely not to have
received the Pap test within
the last three years as
compared with those who
were married.
Age
Women age 3039 were the least likely not to have received a Pap test in the last three years as
compared with women age 4049 or 5064 (9.3 percent versus 12.1 percent and 17.2 percent,
respectively) (figure 1).
Race/ethnicity
Asian non-Hispanic women were more likely not to have received a Pap test within the last three years
(21.5 percent) as compared with white non-Hispanic (13.5 percent), black non-Hispanic (9.9 percent), or
Hispanic (15.6 percent) women (figure 2).
Insurance status
Women age 1864 who were uninsured were more likely to not have received a Pap test within the last
three years (25.4 percent) as compared with those who were covered by private insurance (11.4 percent)
or public insurance (14.9 percent) (figure 3).
Educational level
Women age 1864 who were less educated were more likely not to have received a Pap test within the
last three years. A higher percentage of women with less than high school education reported not having
received a Pap test within the last three years as compared with those who had completed high school or
those who had some college education (23.1 percent versus 15.5 percent and 9.9 percent, respectively)
(figure 4).
Marital status
Women age 1864 who were single (never married) were nearly twice as likely not to have received a
Pap test within the last three years as those who were married (19.0 percent versus 10.3 percent,
respectively) (figure 5).
Data Source
The estimates in this Statistical Brief were derived from the MEPS 2005 full-year population
characteristics data file (HC-090).
Definitions
The question related to receiving a Pap test was asked in the Preventive Care section of MEPS-HC.
Pap test
The Pap test (sometimes called a Pap smear) is a way to examine cells collected from the cervix. The
main purpose of the Pap test is to detect cancer or abnormal cells that may lead to cancer. It can also find
non-cancerous conditions, such as infection and inflammation.
Racial and ethnic classifications
Classification by race/ethnicity is based on information reported for each family member. Respondents
were asked if each family member was Hispanic or Latino. Respondents were also asked which race or
races best describes each family member. Race categories include white, black/African American,
American Indian or Alaska Native, Asian, Native Hawaiian or other Pacific Islander, and other. Based on
these questions, sample persons were classified into the following race/ethnicity categories: Hispanic,
white non-Hispanic single race, black non-Hispanic single race, Asian non-Hispanic single race, and other
(Hawaiian/pacific Islander non-Hispanic, American Indian/Alaska Native non-Hispanic, and multiple races
non-Hispanic).
Marital status
The category No Longer Married includes the women who are widowed, divorced or separated.
Educational level
Educational level indicates a persons number of years of education at the time of the first MEPS
interview:
-
Less than high school = Less than 12 years of education
-
High school graduate = Completed 12 years of education
-
At least some college = More than 12 years of education
Within the last three years
This refers to the three years before the MEPS interview in which this question was asked.
Health insurance status
Individuals under age 65 were classified in the following three insurance categories based on household
responses to health insurance status questions:
-
Any private health insurance: Individuals who, at any time during the year, had insurance that provides
coverage for hospital and physician care (other than Medicare, Medicaid, or other public
hospital/physician coverage) were classified as having private insurance. Coverage by TRICARE
(Armed Forcesrelated coverage) was also included as private health insurance. Insurance that
provides coverage for a single service only, such as dental or vision coverage, was not included.
-
Public coverage only: Individuals were considered to have public coverage only if they met both of the
following criteria: 1) they were not covered by private insurance at any time during the year, and 2) they
were covered by one of the following public programs at any point during the year: Medicare, Medicaid,
or other public hospital/physician coverage.
-
Uninsured: The uninsured were defined as people not covered by private hospital/physician insurance,
Medicare, TRICARE, Medicaid, or other public hospital/physician programs at any time during the entire
year or period of eligibility for the survey.
About MEPS-HC
MEPS-HC is a nationally representative longitudinal survey that collects detailed information on health
care utilization and expenditures, health insurance, and health status, as well as a wide variety of social,
demographic, and economic characteristics for the civilian noninstitutionalized population. It is cospon-
sored by the Agency for Healthcare Research and Quality and the National Center for Health Statistics.
