What is known about this topic?
Zika virus is transmitted through the bite of an Aedes species mosquito, sex with an infected partner, or from a pregnant woman to her fetus. Zika virus infection during pregnancy is a cause of congenital microcephaly and other severe fetal brain defects. It has also been associated with eye defects, hearing loss, and impaired growth. Nearly half of all pregnancies in the United States are unintended. Among nonpermanent contraceptive methods, long-acting reversible contraception (LARC) is the most effective contraceptive option for preventing unintended pregnancy.
What is added by this report?
State-based estimates of contraception use are provided for nonpregnant and postpartum women at risk for unintended pregnancy and sexually active female high school students. Among these populations, use of moderate and less effective contraception was most common; use of no contraceptive method and use of LARC varied by state, age group, and race/ethnicity.
What are the implications for public health practice?
State and local strategies are needed to increase access to contraceptive methods and related services, reduce the risk for unintended pregnancy, and minimize the number of pregnancies affected by Zika infection. Potentially effective strategies include addressing policies on high device costs and provider reimbursement, comprehensive provider training on insertion and removal of LARC, provision of youth-friendly services, support to resource-challenged jurisdictions, client-centered counseling and assessment of patient satisfaction, and increased consumer awareness of the full range of contraceptive methods to delay or avoid pregnancy.
Zika virus infection during pregnancy can cause congenital microcephaly and brain abnormalities (1,2). Since 2015, Zika virus has been spreading through much of the World Health Organization’s Region of the Americas, including U.S. territories. Zika virus is spread through the bite of Aedes aegypti or Aedes albopictus mosquitoes, by sex with an infected partner, or from a pregnant woman to her fetus during pregnancy.* CDC estimates that 41 states are in the potential range of Aedes aegypti or Aedes albopictus mosquitoes (3), and on July 29, 2016, the Florida Department of Health identified an area in one neighborhood of Miami where Zika virus infections in multiple persons are being spread by bites of local mosquitoes. These are the first known cases of local mosquito-borne Zika virus transmission in the continental United States.† CDC prevention efforts include mosquito surveillance and control, targeted education about Zika virus and condom use to prevent sexual transmission, and guidance for providers on contraceptive counseling to reduce unintended pregnancy. To estimate the prevalence of contraceptive use among nonpregnant and postpartum women at risk for unintended pregnancy and sexually active female high school students living in the 41 states where mosquito-borne transmission might be possible, CDC used 2011–2013 and 2015 survey data from four state-based surveillance systems: the Behavioral Risk Factor Surveillance System (BRFSS, 2011–2013), which surveys adult women; the Pregnancy Risk Assessment Monitoring System (PRAMS, 2013) and the Maternal and Infant Health Assessment (MIHA, 2013), which surveys women with a recent live birth; and the Youth Risk Behavior Survey (YRBS, 2015), which surveys students in grades 9–12. CDC defines an unintended pregnancy as one that is either unwanted (i.e., the pregnancy occurred when no children, or no more children, were desired) or mistimed (i.e., the pregnancy occurred earlier than desired). The proportion of women at risk for unintended pregnancy who used a highly effective reversible method, known as long-acting reversible contraception (LARC), ranged from 5.5% to 18.9% for BRFSS-surveyed women and 6.9% to 30.5% for PRAMS/MIHA–surveyed women. The proportion of women not using any contraception ranged from 12.3% to 34.3% (BRFSS) and from 3.5% to 15.3% (PRAMS/MIHA). YRBS data indicated that among sexually active female high school students, use of LARC at last intercourse ranged from 1.7% to 8.4%, and use of no contraception ranged from 7.3% to 22.8%. In the context of Zika preparedness, the full range of contraceptive methods approved by the Food and Drug Administration (FDA), including LARC, should be readily available and accessible for women who want to avoid or delay pregnancy. Given low rates of LARC use, states can implement strategies to remove barriers to the access and availability of LARC including high device costs, limited provider reimbursement, lack of training for providers serving women and adolescents on insertion and removal of LARC, provider lack of knowledge and misperceptions about LARC, limited availability of youth-friendly services that address adolescent confidentiality concerns, inadequate client-centered counseling, and low consumer awareness of the range of contraceptive methods available.
BRFSS is a cross-sectional, random-digit–dialed, state-based telephone survey that collects data on risk behaviors and preventive health practices among adult respondents living in all 50 states, the District of Columbia, Puerto Rico, Guam, and the U.S. Virgin Islands.§ Data from 17 states that might be at risk for mosquito-borne transmission of Zika virus (3) and had implemented questions on self-reported contraceptive use as part of the BRFSS Family Planning module in 2011 or as state-added questions in 2012 or 2013 were used to estimate use of contraception among women aged 18–44 years at risk for unintended pregnancy.¶ PRAMS is an ongoing state-based and population-based surveillance system designed to monitor selected self-reported maternal behaviors and experiences that occur before, during, and after pregnancy among women who recently delivered a live-born infant.** Data from 28 PRAMS states, reporting in 2013, were used to estimate contraceptive use at the time of the survey (4–6 months postpartum) among women aged 15–44 years with a recent live birth who were at risk for unintended pregnancy.†† PRAMS sites were included if they might be at risk for mosquito-borne transmission of Zika virus (3) and achieved a weighted response rate of ≥55%.§§ The 2013 MIHA was used to estimate contraceptive use for postpartum women in California. Using methods comparable to PRAMS, MIHA is an annual, statewide-representative survey of women with a recent live birth.¶¶ YRBSs are conducted by state health and education agencies among representative samples of students in grades 9–12, to monitor health-risk behaviors, including sexual behaviors related to unintended pregnancy and sexually transmitted diseases.*** Data from 2015 YRBSs conducted in 28 states that might be at risk for mosquito-borne transmission of Zika virus (3) were used to describe contraceptive use among female high school students at last sexual intercourse.†††
For all data sources, contraceptive use was classified according to the estimated percentage of users who experience pregnancy during the first year of typical use as highly effective (<1%), moderately effective (6%–10%), and less effective (>10%) (4). Among women reporting more than one contraceptive method, the most effective method was coded. Highly effective, permanent contraceptive methods included female sterilization, tubal ligation, or partner vasectomy. Highly effective LARC methods included intrauterine devices (IUDs) and contraceptive implants. Moderately effective contraceptive methods included hormone injections, contraceptive pills, transdermal contraceptive patches, and vaginal rings. Less effective methods included diaphragm, condoms (male or female), cervical cap, sponge, withdrawal, spermicide, fertility-based awareness methods, emergency contraception, and “other.” Data for the use of permanent contraceptive methods, although included in the denominator for calculating percentages, are not presented because women reporting female sterilization or partner vasectomy do not need ongoing contraceptive services.§§§
Weighted prevalence estimates and 95% confidence intervals for contraceptive use were calculated overall and by age group, as appropriate (BRFSS: ages 18–24, 25–34, and 35–44 years; PRAMS/MIHA: ages 15–19, 20–24, 25–34, and 35–44 years) and by race/ethnicity (non-Hispanic white [white], non-Hispanic black [black], and Hispanic). For all surveys, non-Hispanic other race was included in the denominator, but not presented because of small sample sizes. PRAMS/MIHA data were used to estimate the prevalence of contraceptive use by insurance status (private insurance, Medicaid, and none)¶¶¶; other insurance was not presented because of small sample sizes. Estimates were excluded when they did not meet the reliability standard established for each surveillance system.****
In the 17 states for which BRFSS data were available, use of LARC at last sexual intercourse among women aged 18–44 years at risk for unintended pregnancy ranged from 5.5% (Arizona) to 18.9% (Utah) (Table 1). The proportion of women at risk for unintended pregnancy who used no contraception was lowest in Vermont (12.3%) and highest in Tennessee (34.3%). For all states, moderately and less effective contraception use was lower among older women (available at https://stacks.cdc.gov/view/cdc/40511). Use of less effective contraception was more common among Hispanic women than among white women (available at https://stacks.cdc.gov/view/cdc/40511).
PRAMS and MIHA data indicated that the proportion of women aged 15–44 years at risk for unintended pregnancy using LARC during the postpartum period ranged from 6.9% (New Jersey) to 30.5% (Utah) (Table 2) and was typically highest among adolescents aged 15–19 years (available at https://stacks.cdc.gov/view/cdc/40512). The proportion of postpartum women at risk for unintended pregnancy who did not use contraception ranged from 3.5% (Vermont) to 15.3% (Hawaii). In general, use of LARC and moderately effective contraception was lower in older women (available at https://stacks.cdc.gov/view/cdc/40512). The proportion of women using less effective contraceptive methods tended to be higher among white and Hispanic women than black women (available at https://stacks.cdc.gov/view/cdc/40512). Among women with no insurance, use of LARC ranged from 5.3% (New Jersey) to 34.2% (Utah) (available at https://stacks.cdc.gov/view/cdc/40513).
YRBS data indicated that among currently sexually active female high school students in 28 states, LARC use ranged from <2% (North Carolina and Pennsylvania) to 8.4% (Vermont) (Table 3). Use of less effective contraceptive methods ranged from 36.3% (Vermont) to 59.9% (Florida); the proportion of sexually active female high school students not using any contraception was lowest in Vermont (7.3%) and highest in Arkansas (22.8%). Limited data were available to describe sexually active female high school students using contraception by method effectiveness and race/ethnicity (available at https://stacks.cdc.gov/view/cdc/40514).
During 2011–2013 and 2015, nonpregnant and postpartum women at risk for unintended pregnancy, and sexually active female high school students in states that might be at risk for mosquito-borne transmission of Zika virus, used moderately effective and less effective contraceptive methods most frequently; use of no contraception varied among states. LARC was used by fewer than one fourth of nonpregnant women, approximately one third of women who recently delivered a live birth, and fewer than one tenth of sexually active female high school students. LARC use also varied by state, age group, race/ethnicity, and insurance status. Increasing accessibility of contraceptive services, including LARC, can reduce unintended pregnancy, including the number of pregnancies affected by Zika virus infection among women who are returning, or whose partners are returning, from areas with ongoing Zika virus transmission (5).
Despite the availability of a wide range of FDA-approved contraceptives, unintended pregnancy remains common in the United States; the most recent estimates indicate that 45% of all pregnancies are unintended (6), with variation across states (7) and by age group, income, education, and race/ethnicity (6). LARC methods are highly effective, reversible methods for reducing unintended pregnancy, do not depend on user compliance, and are medically appropriate for most female adolescents and adult women (4,8). Nationally, although use of LARC methods nearly doubled in recent years (9), use remains lower than that of other reversible contraceptives such as oral contraceptive pills and condoms (9), and considerable barriers to access and contraceptive method availability remain (10).
The most recent estimates for the United States suggest that lower income women had rates of unintended pregnancy up to five times higher than women with higher incomes (6). During 2000–2010, the need for publicly funded contraceptive services increased 17% (11).†††† Although publicly funded providers met approximately 42% of contraceptive need in 2013, unmet need varied by state, suggesting gaps in access to subsidized contraceptive care (11). Among low income women with Medicaid insurance, recent guidance emphasizes provision of contraceptive services without cost-sharing.§§§§ Also, whereas women with private insurance coverage reported decreased out-of-pocket costs for LARC following the 2012 Affordable Care Act requirement for most private health plans to cover contraceptive services, 13% of women continued to cost-share (12), further highlighting differences in access and availability (13). Although federal regulations for publicly funded coverage enable minors to obtain contraceptive care without parental consent, private insurers often follow state laws, which vary by jurisdiction, potentially limiting access (14). To improve access and availability to the full range of contraception, a number of state-level and jurisdictional-level strategies exist and could be adopted by state and local agencies (Box).
The findings in this report are subject to at least five limitations. First, information on contraceptive use was self-reported and might be subject to recall or social desirability bias, and response rates varied by state and surveillance system.¶¶¶¶ Second, consistent and correct use of contraception affects effectiveness rates, and this was not measured. Third, population estimates are generalizable only to specific populations for which data are collected; for example, estimates among sexually active female high school students are not generalizable to adolescents who do not attend school. Fourth, the current contraceptive use profile in states might have changed since the data were collected. Finally, only 39 of the 41 states had data from at least one surveillance system, highlighting the need for ongoing collection of state-level data on contraceptive use (3).*****
State-level strategies for increasing access to the full range of FDA-approved contraceptive methods and related services can reduce unintended pregnancies among women, including women who might be exposed to Zika virus. CDC supports states in 1) implementing vector control strategies; 2) identifying, diagnosing, and clinically managing infection and exposure among pregnant women; and 3) increasing information about effective contraception to avoid unintended pregnancy (15). Prevention efforts for all women and men of reproductive age include targeted education about Zika virus and its transmission, condom use to avoid sexual transmission to pregnant women, and contraceptive counseling for women who want to delay or avoid pregnancy (15). Because contraception is the primary means to prevent unintended pregnancy for women at risk for Zika virus infection, sexually active nonpregnant women of reproductive age and their sex partners need to have access to all approved contraceptive methods, and these methods need to be readily available and accessible.
