Abstract
Abstract Objective The objective was to examine levels of, correlates of and changes in the use of individual and grouped methods of contraception among US females aged 15–44 from 2008 to 2014. Study design Using three rounds of the National Survey of Family Growth, we analyzed samples of 12,279 (2008), 5601 (2012) and 5699 (2014) females. We conducted simple and multivariable logistic regression analyses to identify associations between demographic characteristics and contraceptive use, as well as between characteristics and changes in use patterns. Results In terms of overall trends in contraceptive use between 2008 and 2014, there was no significant change in the proportion of women who used a method among either all women (60%) or those at risk of unintended pregnancy (90%). Significant changes in use occurred among six methods. The largest increase in use was among users of long-acting reversible contraceptive (LARC) methods, including the intrauterine device and implant — from 6% to 14% — across almost all population groups of female contraceptive users, while the largest decrease occurred among users of sterilization — from 37% to 28% — with lower-income women driving the decline in female sterilization and higher-income women driving the decline in a partner's sterilization as a primary method. Moderate increases were seen in the use of withdrawal and natural family planning. Conclusion Most shifts in recent contraceptive use have occurred among the most effective methods — sterilization and LARCs. Differences in method-specific user characteristics underscore the importance of ensuring full access to the broad range of methods available. Implications The lack of change in the overall use of contraceptives among women at risk for unintended pregnancy may have implications for the extent to which further declines in national rates of unintended pregnancy can be expected.

Abstract Although many impacts of the Affordable Care Act (ACA) have been well studied, less attention has been paid to whether use of contraceptives (especially those covered by health insurance) changed in young adults. The ACA did several things that might influence contraceptive use: allowed children to stay on a parent's health insurance until age 26, required insurers to impose no co-payment for contraceptives beginning in 2012, and increased funding for family planning services. The autho...

Abstract Background The Affordable Care Act (ACA) substantially increased rates of insurance coverage within the first year of implementation, including among women of reproductive age. The ACA also requires that private insurance plans cover contraceptives without any out-of-pocket costs. These provisions may have led more women to start using prescription contraception. Study Design We conducted two cross-sectional studies, collecting data from 8,062 women aged 18 to 39 in the fall 2012 and sp...

CONTEXT Contraceptive failure rates measure a woman's probability of becoming pregnant while using a contraceptive. Information about these rates enables couples to make informed contraceptive choices. Failure rates were last estimated for 2002, and social and economic changes that have occurred since then necessitate a reestimation. METHODS To estimate failure rates for the most commonly used reversible methods in the United States, data from the 2006–2010 National Survey of Family Growth were ...

CONTEXT National and state-level information about abortion incidence can help inform policies and programs intended to reduce levels of unintended pregnancy. METHODS In 2015–2016, all U.S. facilities known or expected to have provided abortion services in 2013 or 2014 were surveyed. Data on the number of abortions were combined with population data to estimate national and state-level abortion rates. The number of abortion-providing facilities and changes since a similar 2011 survey were also a...

Patient cost sharing for contraceptive prescriptions was eliminated for certain insurance plans as part of the Affordable Care Act. We examined the impact of this change on women’s patterns of choosing prescription contraceptive methods. Using claims data for a sample of midwestern women ages 18–46 with employer-sponsored coverage, we examined the contraceptive choices made by women in employer groups whose coverage complied with the mandate, compared to the choices of women in groups whose cove...

The oral contraceptive pill is the contraceptive method most commonly used by US women, but inconsistent use of the pill is a contributor to high rates of unintended pregnancy. The relationship between consumer cost sharing and consistent use of the pill is not well understood, and the impact of the elimination of cost sharing for oral contraceptive pills in a mandate in the Affordable Care Act (ACA) is not yet known. We analyzed insurance claims for 635,075 women with employer-sponsored insuran...

What factors and subgroups have propelled the recent increase in intrauterine device (IUD) use in the USA?The increase in IUD use, from 1.8 to 9.5% in the USA between 2002 and 2012, was driven primarily by a marked uptake among parous women who intended to have more children.Recent data suggest an unprecedented increase in IUD use among women in the USA, yet less is known about how this increase has affected the overall proportion of women, at risk of unintended pregnancy, who are using contrace...

How contraceptives affect women’s sexual well-being is critically understudied. Fortunately, a growing literature focuses on sexual aspects of contraception, especially hormonal contraception’s associations with libido. However, a more holistic approach to contraceptive sexual acceptability is needed to capture the full range of women’s sexual experiences. We conducted a narrative literature review of this topic, working with an original sample of 3,001 citations published from 2005 to 2015. In ...

Despite clinical guidelines and national data describing the use of one contraceptive method as the best and most common way to prevent unintended pregnancy, limited evidence indicates a more complex picture of actual contraceptive practice. Face-to-face in-depth interviews were conducted in November of 2013 with a sample of women from two cities in the United States (n = 52). The interviews explored the ways participants used contraception to protect themselves from unintended pregnancy over th...

Background: The Covid-19 pandemic has introduced acute and persistent psychosocial stressors for many individuals, with emerging gender differences that suggest women may be at greater risk for poorer mental health outcomes. This may have unintended consequences for women's overall health and well-being, including disruptions to reproductive function as elevated stress is often associated with menstrual cycle irregularities. The objective of this study was to determine if and how the Covid-19 pa...

A major shift in the U.S. contraceptive method mix has been the recent growth in the use of long-acting reversible contraceptives (LARCs)—intrauterine devices and implants. Quantitative research into LARC’s impacts until now has focused on evaluating their efficacy in reducing unintended pregnancies. The next question, of whether births after discontinuing LARC use are then more likely to result from an intended pregnancy, has received almost no attention. We analyzed data from 2984 women who re...

Adolescents are at risk for unwanted pregnancy when they become sexually active, and contraception is an important part of mitigating this risk. Use of contraceptive methods, and long-acting reversible contraceptive methods such as implants and intrauterine devices in particular, has increased among adolescents. Although sexual activity has declined and contraceptive use has increased among adolescents in the United States in recent years, the unintended pregnancy rate remains high. All of the c...

Abstract Objective : To evaluate the likelihood of a short inter-pregnancy interval (IPI) resulting in a birth among women covered by Medicaid, as a function of postpartum contraceptive method type. Study Design : We used Medicaid claims and eligibility data to identify women (aged 15-44) who had a Medicaid-financed birth in Delaware in the years 2012-2014 (n=10,328). Claims were analyzed to determine postpartum contraceptive type within 60 days of the index birth, and linked birth certificates ...

BACKGROUND In the United States, up to 57% of women report resumption of sexual activity by the 6 week postpartum visit. Effective contraception should be addressed and provided at that time, to avoid unintended pregnancies and optimize interpregnancy intervals. Long-acting reversible contraceptives are the most effective forms of reversible contraception and are increasingly popular during the postpartum period. However, timing of postpartum intrauterine device (IUD) placement varies among prov...

INTRODUCTION Metabolome variations have long been associated with normal hormonal fluctuations, and similar effects, related to the use of early generation synthetic hormones as a means of contraception, have also been identified. OBJECTIVE We investigated the serum amino acid and acylcarnitine profiles induced by the use of combined oral contraceptives (COCs) consisting of Ethinylestradiol (EE) and a 4th generation progestin, Drospirenone (DRSP). METHOD Gas chromatography mass spectrometry and ...

Women have more difficulty maintaining smoking cessation than men, and experience greater withdrawal symptomatology as well as higher prevalence of relapse. Further, currently available treatments for smoking cessation, such as the nicotine patch and varenicline, have been shown to be less effective in women. Fluctuations in ovarian hormones across the menstrual cycle can affect craving and smoking relapse propensity. In addition, many women who smoke use some form of oral contraceptives, which ...
