Background
Many women with opioid use disorder (OUD) do not use highly effective postpartum contraception such as long-acting reversible contraception (LARC). We evaluated factors associated with prenatal intent and postpartum receipt of LARC among women receiving medication-assisted treatment (MAT) for OUD.Study design
This was a retrospective cohort study of 791 pregnant women with OUD on MAT who delivered at an academic institution without immediate postpartum LARC services between 2009 and 2012. LARC intent was defined as a documented plan for postpartum LARC during pregnancy and LARC receipt was defined as documentation of LARC placement by 8 weeks postpartum. We organized contraceptive methods into five categories: LARC, female sterilization, short-acting methods, barrier methods and no documented method. Multivariable logistic regression identified characteristics predictive of prenatal LARC intent and postpartum LARC receipt.Results
Among 791 pregnant women with OUD on MAT, 275 (34.8%) intended to use postpartum LARC and only 237 (29.9%) attended the postpartum visit. Among 275 women with prenatal LARC intent, 124 (45.1%) attended their postpartum visit and 50 (18.2%) received a postpartum LARC. Prenatal contraceptive counseling (OR 6.67; 95% CI 3.21, 13.89) was positively associated with LARC intent. Conversely, older age (OR 0.95; 95% CI 0.91, 0.98) and private practice provider (OR 0.48; 95% CI 0.32, 0.72) were negatively associated with LARC intent. Although parity was not predictive of LARC intent, primiparous patients (CI 0.49; 95% CI 0.26, 0.97) were less likely to receive postpartum LARC.Conclusions
Discrepancies exist between prenatal intent and postpartum receipt of LARC among pregnant women with OUD on MAT. Immediate postpartum LARC services may reduce LARC access barriers.Implications
Despite prenatal interest in using LARC, most pregnant women with OUD on MAT did not receive postpartum LARC. The provision of immediate postpartum LARC services may reduce barriers to postpartum LARC receipt such as poor attendance at the postpartum visit. 相似文献2.

Background
The postpartum period is an opportune time for contraception adoption, as women have extended interaction with the reproductive healthcare system and therefore more opportunity to learn about and adopt contraceptive methods. This may be especially true for women who experience unintended pregnancy, a key target population for contraceptive programs and programs to eliminate mother-to-child HIV transmission. Among women in Zimbabwe surveyed in 2014, we examined the relationship between pregnancy intention associated with a woman’s most recent pregnancy, and her subsequent postpartum contraceptive use.Methods
In our analysis we utilized a dataset from a random selection of catchment areas in Zimbabwe to examine the association between pregnancy intention of most recent pregnancy and subsequent postpartum contraceptive use using multinomial logistic regression models. We also explored whether this association differed by women’s HIV status. Finally, we examined the association between pregnancy intention and changes in contraception from the pre- to postpartum periods.Results
Findings suggest that women who reported that their pregnancy was unintended adopted less modern (all non-traditional) contraceptive methods overall, but adopted long-acting reversible contraception (LARC) more frequently than women reporting an intended pregnancy (OR 1.41; CI 1.18, 1.68). Among HIV-positive women, this relationship was particularly strong (OR 3.12; CI 1.96, 4.97). However, when examining changes in contraceptive use from the pre-pregnancy to the postpartum period, women who had an unintended pregnancy had lower odds of changing to a more effective method postpartum overall (OR 0.71; CI 0.64, 0.79).Conclusions
We did not find evidence of higher modern method adoption in the postpartum period among women with an unintended pregnancy. However, women who were already on a method in the pre-pregnancy period were catalyzed to move to more effective methods (such as LARC) postpartum. This study provides evidence of low modern (non-traditional) method adoption in general in the postpartum period among a vulnerable sub-population in Zimbabwe (women who experience unintended pregnancy). Simultaneously, however, it shows a relatively greater portion specifically of LARC use among women with an unintended pregnancy. Further research is needed to more closely examine the motivations behind these contraceptive decisions in order to better inform distribution and counseling programs.3.

Objective
The objective was to characterize uptake and correlates of effective contraceptive use postpartum.Study design
We analyzed data from a national, cross-sectional evaluation of prevention of mother-to-child HIV transmission programs that enrolled women attending 6-week or 9-month infant immunization visits at 120 Kenyan maternal and child health clinics. We classified women who resumed sexual activity postpartum and did not desire a child within 2 years as having a need for family planning (FP).Results
We included 955 (94%) of 1012 women 8–10 months postpartum in the analysis. Mean age was 25.8 years and 36% were primigravidas. By 9 months postpartum, 62% of all women used contraception and 59% used effective contraception [injectables, implants, intrauterine devices [IUDs], oral contraceptives [OCs] and tubal ligations]. Most contraceptive users (61%) used injectables, followed by implants (10%), OCs (6%), IUDs (4%) and condoms alone (2%). The majority (n=733, 77%) had a need for FP, and 67% of 733 women with FP need used effective contraception. Among women with a need for FP, effective contraception use was higher among those who discussed FP in postnatal care (PNC) than who did not discuss FP in PNC [prevalence ratio (PR) for PNC alone: 1.35, 95% confidence interval (CI): 1.16–1.58; PR for PNC and antenatal care (ANC): 1.42, 95% CI: 1.21–1.67; p=.001 for both].Conclusions
Two thirds of postpartum women with a need for FP used effective contraception at 9 months postpartum, and use was associated with discussing FP during PNC.Implications
Integrating FP counseling in ANC/PNC could be an effective strategy to increase effective contraception use. 相似文献4.
Objective
We sought to determine the prevalence of postpartum contraceptive use among women with postpartum depressive symptoms (PDS) and examine the association between PDS and contraceptive method.Study design
We evaluated data from 16,357 postpartum women participating in the 2009–2011 Pregnancy Risk Assessment Monitoring System. PDS was defined as an additive score of ≥10 for three questions on depression, hopelessness, and feeling physically slowed. Contraceptive use was categorized as permanent, long-acting reversible contraception (LARC), user-dependent hormonal, and user-dependent non-hormonal. Logistic regression models compared postpartum contraceptive use and method by PDS status.Results
In total, 12.3% of women with a recent live birth reported PDS. Large percentages of women with (69.4%) and without (76.1%) PDS, used user-dependent or no contraceptive method. There were no associations between PDS and use of any postpartum contraception (adjusted Prevalence Ratio (aPR) = 1.00, 95% CI 0.98–1.03) or permanent contraception (aPR=1.05, 95% CI 0.88–1.27). LARC use was elevated, but not significantly, among women with PDS compared to those without (aPR=1.16, 95% CI: 1.00–1.34).Conclusions
Large percentages of women with and without PDS used user-dependent or no contraception. Since depression may be associated with misuse of user-dependent methods, counseling women about how to use methods more effectively, as well as the effectiveness of non-user dependent methods, may be beneficial.Implications
A large percentage of women with PDS are either not using contraception or using less effective user-dependent methods. Since depression may be associated with misuse of user-dependent contraceptive methods, counseling women about how to use methods more effectively, as well as non-user dependent options, such as LARC, may be beneficial. 相似文献5.

Objective
This study assessed whether immediate postpartum insertion of levonorgestrel contraceptive implants is associated with a difference in infant growth from birth to 6 months, onset of lactogenesis, or breastfeeding continuation at 3 and 6 months postpartum compared to delayed insertion at 6 to 8 weeks postpartum.Study design
We conducted a randomized trial of women in Uganda who desired contraceptive implants postpartum. We randomly assigned participants to receive either immediate (within 5 days of delivery) or delayed (6 to 8 weeks postpartum) insertion of a two-rod levonorgestrel contraceptive implant system. This is a prespecified secondary analysis evaluating breastfeeding outcomes. The primary outcome of this secondary analysis was change in infant weight; infants were weighed and measured at birth and 6 months. We used a validated questionnaire to assess onset of lactogenesis daily in person while participants were in the hospital, and then daily by phone after they left the hospital, until lactogenesis was documented. We used interviewer-administered questionnaires to assess breastfeeding continuation and concerns at 3 months and 6 months postpartum.Results
Among the 96 women randomized to the immediate group and the 87 women to the delayed group, the mean change in infant weight from birth to 6 months was similar between groups: 4632?g in the immediate group and 4407?g in the delayed group (p=.26). Among the 97 women who had not experienced lactogenesis prior to randomization, the median time to onset of lactogenesis did not differ significantly between the immediate and delayed groups (65?h versus 63?h; p=.84). Similar proportions of women in the immediate and delayed groups reported exclusive breastfeeding at 3 months (74% versus 71%; p=.74) and 6 months (48% versus 52%; p=.58).Conclusion
We found no association between the timing of postpartum initiation of levonorgestrel contraceptive implants and change in infant growth from birth to 6 months, onset of lactogenesis, or breastfeeding continuation at 3 or 6 months postpartum.Implications
This study provides evidence that immediate postpartum initiation of contraception implants does not have a deleterious effect on infant growth or initiation or continuation of breastfeeding. 相似文献6.

Objective
To assess the impact of contraceptive counseling on the uptake of long-acting reversible contraception (LARC), namely, intrauterine devices and the contraceptive implant, by 3 months postpartum among women with a recent preterm birth.Design
We enrolled patients in a single-blinded, one-to-one, randomized, controlled trial to assess the impact of enhanced family planning counseling immediately after a viable preterm birth in the inpatient setting. Participants received either structured counseling with an emphasis on LARC by a family planning specialist (intervention) or routine postpartum care (control). We followed participants to the primary outcome of LARC use 3 months postpartum.Results
We followed 121 participants for 3 months. Primary outcome data were available for 119 participants (61 intervention, 58 control). We found no demographic differences between the groups. Participants in the intervention group were significantly more likely to use LARC at 3 months postpartum compared with controls (51% vs. 31%; p < .05). For every six women who received the counseling intervention, one additional woman was using a LARC method at 3 months.Conclusions
After a preterm birth, brief LARC-focused, structured counseling before hospital discharge significantly increased LARC method use at 3 months postpartum. 相似文献7.
Objectives
Postpartum contraception plays a significant role in reducing subsequent pregnancy. However, young mothers in Ottawa, the capital of Canada, face various barriers when trying to access contraception after delivery. Through this project, we aimed to explore these barriers and understand the decision-making processes of young mothers surrounding postpartum contraception.Study design
We conducted 10 semistructured in-depth interviews with young mothers living in Ottawa who had experienced a subsequent pregnancy within 24 months of their first childbirth. In addition, we interviewed 10 key informants who work with teenage mothers. We audio-recorded and transcribed all interviews and analyzed them using inductive and deductive techniques. We used ATLAS.ti software to manage our data.Results
Both young mothers and key informants report that teen mothers in Ottawa often do not use postpartum contraception or inconsistently use their chosen contraceptive method. Many factors, including cost, personal beliefs, personal priorities and knowledge, influence young mothers' decision making surrounding contraception.Conclusions
Our study suggests that when young mothers do not use postpartum contraception, the reasons are complex; for some, this is a choice, and for others, this is the result of systems-level, service delivery and information barriers. Supporting policies to ensure that a full range of contraceptive methods are available and affordable and developing educational programs in Ottawa that are sex-positive and nonjudgmental appear warranted.Implications
Ensuring that a full method mix, including contraceptive implants, is available to and affordable for young mothers in Ottawa could meet significant needs. Addressing existing systems-level, service delivery and information barriers through supporting evidence-based policies and sex-positive and nonjudgmental educational programs appears warranted. 相似文献8.

Objective
We sought to evaluate the impact of insurance type on receipt of an interval postpartum LARC, controlling for demographic and clinical factors.Study design
This is a retrospective cohort study of 1072 women with a documented plan of LARC for contraception at time of postpartum discharge. This is a secondary analysis of 8654 women who delivered at 20 weeks or beyond from January 1, 2012, through December 31, 2014, at an urban teaching hospital in Ohio. LARC receipt within 90 days of delivery, time to receipt, and rate of subsequent pregnancy after non-receipt were compared between women with Medicaid and women with private insurance. Postplacental LARC was not available at the time of study completion.Results
One hundred eighty-seven of 822 Medicaid-insured and 43 of 131 privately insured women received a LARC postpartum (22.7% vs 32.8%, P=.02). In multivariable analysis, private insurance status was not significantly associated with LARC receipt (OR 1.29, 95% C.I. 0.83–1.99) though adequate prenatal care was (OR 2.33, 95% C.I. 1.42–4.00). Of women who wanted but did not receive a LARC, 208 of 635 (32.8%) Medicaid patients and 19 of 88 (21.6%) privately insured patients became pregnant within 1 year (P=.02).Conclusion
Differences in receipt of interval postpartum LARC were not significant between women with Medicaid insurance versus private insurance after adjusting for clinical and demographic factors. Adequate prenatal care was associated with LARC receipt. Medicaid patients who did not receive a LARC were more likely to become pregnant within one year of delivery than those with private insurance.Implications
While insurance-related barriers have been reduced given recent policy changes, access to care remains an important determinant of postpartum LARC provision and subsequent unintended pregnancy. 相似文献9.
Objective
This study examined whether women with Medicaid are less likely to receive long-acting reversible contraception (LARC) in a clinic requiring two visits for insertion.Study design
LARC insertion and pregnancy rates were compared among women with Medicaid vs. private insurance, along with other predictors, in a retrospective chart review (N=447).Results
Univariately, fewer women with Medicaid vs. private insurance received LARC (66% vs. 79%, p<.01) and more become pregnant (18% vs. 6%, p<.001). Significant multivariate predictors of not receiving LARC were being unmarried and postpartum, both of which were associated with having Medicaid.Conclusion
Women with Medicaid are less likely than women with private insurance to have a requested LARC device inserted when a clinic requires two visits for insertion. 相似文献10.

Objective
To explore patient experiences of contraceptive coercion by healthcare providers at time of abortion.Study Design
We conducted a qualitative study of English-speaking women seeking abortion services at a hospital-based clinic. We used the Integrated Behavioral Model and the Reproductive Autonomy Scale to inform our semi-structured interview guide; the Scale provides a framework of reproductive coercion as a lack of autonomy or power to decide about and control decisions relating to reproduction. We enrolled participants until thematic saturation was achieved. Two coders used modified grounded theory to analyze transcribed interviews with Nvivo 11.0 (Κ=0.81).Results
The 31 women we interviewed from June 2016 to March 2017 were all in the first trimester, and predominantly young (mean age 27±5 years), non-Hispanic Black (52%) and Medicaid-insured (68%). Some participants (42%) reported feeling “pressured” into choosing some form of contraception. A subset of participants (26%) voiced that providers seemed to prefer LARC methods or were “pushing” a specific method. Several participants perceived pressure to choose any method due to providers' preference to prevent repeat abortions. Conversely, participants who were offered a range of methods through the use of decision aids and who were given time to deliberate demonstrated more reproductive autonomy.Conclusions
Almost half of participants perceived a form of coercion around their contraceptive counseling. Coercion manifested in perceived provider preference for specific methods or immediate initiation of a method. Participant narratives involving decision aids to offer a range of methods and time for deliberation demonstrated greater reproductive autonomy and less coercion. Abortion stigma may mediate potentially coercive interactions between patients and providers.Implications
This qualitative study explored contraceptive coercion at the time of abortion. Findings highlighted provider pressure to initiate contraception, LARC preference, and abortion stigma. Offering many methods and opportunity for deliberation supported autonomy and satisfaction. Findings inform ongoing efforts to improve contraceptive counseling and promote reproductive autonomy, while addressing unintended pregnancies. 相似文献11.

Objective
To investigate whether demographic, socioeconomic, and reproductive health characteristics affect long-acting reversible contraceptive (LARC) use differently by race-ethnicity. Results may inform the dialogue on racial pressure and bias in LARC promotion.Study design
Data derived from the 2011–2013 and 2013–2015 National Surveys of Family Growth (NSFG). Our study sample included 9321 women aged 15–44. Logistic regression analyses predicted current LARC use (yes vs. no). We tested interaction terms between race-ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic) and covariates (for example, education, parity, poverty level) to explore whether their effects on LARC use vary by race-ethnicity.Results
In the race-interactions model, data did not show that low income and education predict LARC use more strongly among Black and Hispanic women than among White women. There was just one statistically significant race-interaction: experience of unintended pregnancy (p=.014). Among Whites and Hispanics, women who reported ever experiencing an unintended pregnancy had a higher predicted probability of LARC use than those who did not. On the other hand, among Black women, the experience of unintended pregnancy was not associated with a higher predicted probability of LARC use.Conclusions
With the exception of the experience of unintended pregnancy, findings from this large, nationally representative sample of women suggest similar patterns in LARC use by race-ethnicity.Implications
Results from this analysis of NSFG data do not provide evidence that observed differences in LARC use by race-ethnicity represent socioeconomic disparities, and may assuage some concerns about reproductive coercion among women of color. Nevertheless, it is absolutely critical that providers use patient-centered approaches for contraceptive counseling that promote women's autonomy in their reproductive health care decision-making. 相似文献12.

Objective
The objective was to determine if young women initiating long-acting reversible contraceptives (LARCs) who report new sexual partner(s) would be less likely to report use of a condom than women using short-acting reversible contraceptive (SARC) methods.Study design
We enrolled a prospective cohort of 13–24-year-old women attending an adolescent-specific contraception clinic. Participants completed questionnaires at the contraceptive initiation visit and 6 months later. At follow-up, we asked if they had sexual intercourse with a new partner, if they had used condoms, if their condom use patterns had changed and why. We analyzed factors associated with condom use.Results
We enrolled 1048 women; 771 (73.6%) initiated LARC and 384 (36.6%) initiated SARC. At 6 months, 508 participants (48.5%) completed the follow-up survey: 380 LARC initiators and 128 SARC initiators. Approximately 23% of LARC initiators and 27% of SARC initiators reported a new partner. SARC initiators who had a new partner were more likely to report condom use at least one time than LARC initiators reporting a new partner [82.4% vs. 59.6%; odds ratio (OR): 3.17, 95% confidence interval (CI): 1.19–8.43]. Such condom use was 42% higher among LARC initiators who reported a new sexual partner than those without and 38% higher for SARC initiators. In multivariable logistic regression, new sexual partner [adjusted OR (aOR) 3.29, 95% CI 2.10–5.16], SARC initiation (aOR 2.08, 95% CI 1.35–3.22) and age <20 (aOR 1.68, 95% CI 1.14–2.49) were independent predictors of condom use.Conclusion
While young women are less likely to report condom use in the 6 months after initiating a LARC than after initiating a short-acting method, both groups increase their condom use similarly if they report a new sexual partner.Implications
The differential in condom use between LARC initiators and SARC initiators is likely related to their perceived need for pregnancy prevention, as both groups increase their condom use similarly if they had new sexual partners. 相似文献14.

Objective
Researchers traditionally rely on participant self-report for contraceptive use. We hypothesized that self-reported contraceptive use by clinical research participants may disagree with objectively measured hormonal status.Study design
We enrolled women in Harare, Zimbabwe, aged 18–34, who by self-report had not used hormonal or intrauterine contraception for >30 days, or depot medroxyprogesterone acetate for >10 months, into a study designed to assess biologic changes with contraceptive initiation and use. Blood samples obtained at enrollment and each follow-up visit (N=1630 from 447 participants) were evaluated by mass spectrometry for exogenous hormones. We individually interviewed a subset of participants (n=20) with discrepant self-reported and measured serum hormones to better understand nondisclosure of contraceptive use.Results
Discrepant with self-reported nonuse of hormonal contraception, synthetic progestogens were detectable in 120/447 (27%, 95% confidence interval 23%–31%) enrolled women. Measured exogenous hormones consistent with use of contraceptive pills (n=102), injectables (n=20) and implants (n=3) were detected at enrollment, with 7 women likely using >1 contraceptive. In-depth interviews revealed that participants understood the requirement to be hormone free at enrollment (100%). Most (85%) cited partner noncooperation with condoms/withdrawal and/or pregnancy concerns as major reasons for nondisclosed contraceptive use. All interviewed women (100%) cited access to health care as a primary motivation for study participation. Of participants who accurately reported nonuse of hormonal contraception at enrollment, 41/327 (12.5%) had objective evidence of nonstudy progestin use at follow-up that disagreed with self-reported nonuse.Conclusions
Women joining contraceptive research studies may misrepresent their use of nonstudy contraceptive hormones at baseline and follow-up. Objective measures of hormone use are needed to ensure that study population exposures are accurately categorized.Implications statement
Among Zimbabwean women participating in a contraceptive research study, 27% had objective evidence of use of nonstudy contraceptives at enrollment that disagreed with self-report. Studies that rely on self-report to identify contraceptive hormone exposure could suffer from significant misclassification. 相似文献15.

Objective
To compare the proportion of women receiving same-day long-acting reversible contraception (LARC) between two different models of contraceptive provision adapted from the Contraceptive CHOICE Project.Study Design
We used a controlled time-trend study design to compare 502 women receiving structured contraceptive counseling in addition to usual care (“Enhanced Care”) to 506 women receiving counseling plus healthcare provider education and cost support for LARC (“Complete CHOICE”) at three federally qualified health centers. We provided funds to health centers to ensure an “on-the-shelf” supply and no-cost LARC for uninsured women. We recorded the contraceptive method chosen after contraceptive counseling and the healthcare provider appointment as well as the contraceptive method received that day. Among women choosing LARC, we calculated proportions and performed Poisson regression with robust error variance to estimate relative risks for same-day insertion.Results
Participant demographics reflected the health center populations; 69% were black, 66% had a high school diploma or less, 57% were publicly insured, and 75% reported household income less than 101% federal poverty line. There were 153 (30.5%) women in “Enhanced Care” and 273 (54.0%) in “Complete CHOICE” who chose LARC (p<0.01). Among women who chose LARC (n=426), those in “Complete CHOICE” were more likely to receive a same-day insertion, 53.8% vs. 13.7% (RRadj 4.73; 95%CI 3.20–6.98) compared to “Enhanced Care.”Conclusions
A contraceptive care model that included healthcare provider education and cost support for LARC in addition to structured contraceptive counseling resulted in higher rates of same-day LARC insertion compared to contraceptive counseling and usual care alone.Implications
Contraceptive care provision which includes contraceptive counseling, healthcare provider education, and “on-the-shelf”, long-acting reversible contraception facilitate same-day initiation of these methods. Interventions that focus solely on contraceptive counseling do not address other structural barriers to same-day contraceptive provision of all methods including cost and provider practice. 相似文献16.

Objectives
To measure the 24-month impact on continuation, unintended pregnancy and satisfaction of trying long-acting reversible contraception (LARC) in a population seeking short-acting reversible contraception (SARC).Study design
We enrolled 916 women aged 18–29 who were seeking pills or injectables in a partially randomized patient preference trial. Women with strong preferences for pills or injectables started on those products, while others opted for randomization to LARC or SARC and received their methods gratis. We estimated continuation and unintended pregnancy rates through 24 months. Intent-to-treat principles were applied after method initiation for comparing incidence of unintended pregnancy. We also examined how satisfaction levels varied by cohort and how baseline negative LARC attitudes were associated with satisfaction over time.Results
Forty-three percent chose randomization, and 57% chose the preference option. Complete loss to follow-up was<2%. The 24-month LARC continuation probability was 64.3% [95% confidence interval (CI): 56.6–70.9], statistically higher than SARC groups [25.5% (randomized) and 40.0% (preference)]. The 24-month cumulative unintended pregnancy probabilities were 9.9% (95% CI: 7.2–12.6) (preference-SARC), 6.9% (95% CI: 3.3–10.6) (randomized-SARC) and 3.6% (95% CI: 1.8–6.4) (randomized-LARC). Statistical tests for comparing randomized groups on unintended pregnancy were mixed: binomial at 24-month time point (p=.02) and log-rank survival probabilities (p=.14 for first pregnancies and p=.07 when including second pregnancies). LARC satisfaction was high (80% happy/neutral, 73% would use LARC again, 81% would recommend to a friend). Baseline negative attitudes toward LARC (27%) were not clearly associated with satisfaction or early discontinuation.Conclusions
The decision to try LARC resulted in high continuation rates and substantial protection from unintended pregnancy over 24 months. Despite participants' initial desires to begin short-acting regimens, they had high satisfaction with LARC. Voluntary decisions to try LARC will benefit large proportions of typical SARC users.Implications
Even women who do not necessarily view LARC as a first choice may have a highly satisfying experience and avoid unintended pregnancy if they try it. 相似文献18.
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. 相似文献19.
Correlates of long-acting reversible contraception versus sterilization use in advanced maternal age
Shelby N. Apodaca Melissa D. Mendez Sheralyn S. Sanchez Zuber D. Mulla 《Annals of epidemiology》2018,28(7):447-451
Purpose
To identify correlates associated with choosing long-acting reversible contraception (LARC) over female sterilization (FS) from a subsample of women aged 35 to 44 years in a nationally representative survey.Methods
We analyzed data from women aged 35 to 44 years from the 2011–2013 National Survey of Family Growth Female Respondent File (n = 1532). Data were analyzed using SAS 9.3 software. All analyses accounted for the complex survey sample design. Multinomial logistic regression was used to identify factors associated with choosing LARC versus FS. A domain analysis was performed focusing on women aged 35 to 44 years.Results
Approximately 90% of the surveyed women had not received counseling or information about birth control in the past 12 months. Factors associated with using an LARC method versus FS were higher level of education, birth outside of the United States, and higher number of lifetime male sexual partners. Factors associated with using FS versus an LARC method were non-Hispanic black race and women who had not had a checkup related to using a birth control method in the last 12 months.Conclusions
The results of our study suggest that a large proportion of women of advanced maternal age in the United States have not received contraceptive counseling in the past 12 months. Providers should focus on providing comprehensive contraceptive and sterilization counseling to women aged 35 to 44 years, especially those using unreliable, reversible contraception. 相似文献20.
