Trends in Pregnancy Rates in an Urban Adolescent Clinic Before and During the COVID-19 Pandemic.

We examined COVID-19 pandemic-related changes on reproductive health care delivery and pregnancy rates in an adolescent clinic. Through a retrospective data collection as part of quality improvement project, we compared the number of pregnancies, visit percentages for newly diagnosed pregnancies, and number/percentage of long acting reversible contraception (LARC) visits. The percentage of visits for newly diagnosed pregnancies during the first 3 months of the COVID-19 pandemic (April-June 2020) increased significantly relative to pre-pandemic percentages while the absolute number of new pregnancies only trended upward. Over the same timeframe, the total number of LARC visits decreased, although they consisted of a higher percentage of all in-person visits than pre-pandemic. After the first few months of the pandemic, these values returned to pre-pandemic levels. The substantial increase in the rate of new pregnancies during the first 3 to 6 months of the COVID-19 pandemic demonstrates the importance of prioritizing access to reproductive health care services for adolescents and young adults.

Determinants of long acting reversible contraception utilization in Northwest Ethiopia: An institution-based case control study.

BACKGROUND: Though long-acting reversible contraceptives (LARCs) are highly effective, have minimal side effects, require minimal follow-up, and are low cost, only 10% of contraceptives used in Ethiopia are LARCs. The reason for this low uptake is not understood at the country or regional level. Therefore, this study identified determinants of LARC utilization in Northwest Ethiopia. METHODS: A facility-based unmatched case control study, using LARC users as cases and short- acting reversible contraception (SARC) users as controls, had been conducted at fourteen public health institutions in Northwest Ethiopia. A systematic random sampling technique was used to select participants with a 1:2 case to control ratio (n = 1167). Binary logistic regression analysis was used to identify determinants of LARC utilization among family planning service users. RESULTS: Wealth status [AOR:1.87, 95%CI (1.08, 3.24)], history of abortion [AOR:2.69, 95%CI (1.41, 5.12)], limiting family size [AOR: 2.38, 95%CI (1.01, 5.62)], good knowledge about LARCs [AOR: 2.52, 95%CI (1.17, 5.41)], method convenience [AOR: 0.23, 95%CI (0.16, 0.34)], good availability of method [AOR:0.10 (0.05, 0.19)], less frequent visits to health facility [AOR:2.95, 95% CI(1.89, 4.62)], health care providers advice [AOR:10.69, 95%CI (3.27, 34.87)], partner approval [AOR:0.66, 95%CI (0.45, 0.97)], and favorable attitude towards LARCs [AOR:13.0, 95%CI (8.60, 19.72)] were significantly associated with LARC utilization. CONCLUSION: Professional support, favorable attitude towards LARC use, high economic status, history of abortion, advantage of less frequent visits, having good knowledge towards LARC and interest of limiting births were significantly associated with LARC Utilization. On the other hand, perceived method convenience, and contraception availability were inversely associated with it. Family planning education about the benefits of LARC should be done by health providers and media. Male involvement in the counselling and decision making about the advantage of using LARC may improve the negative influence of partners on LARC utilization. It is also recommended that, future qualitative research further explore perceptions of LARC use.

Impact of a pay-for-performance scheme for long-acting reversible contraceptive (LARC) advice on contraceptive uptake and abortion in British primary care: An interrupted time series study.

BACKGROUND: Long-acting reversible contraception (LARC) is among the most effective contraceptive methods, but uptake remains low even in high-income settings. In 2009/2010, a target-based pay-for-performance (P4P) scheme in Britain was introduced for primary care physicians (PCPs) to offer advice about LARC methods to a specified proportion of women attending for contraceptive care to improve contraceptive choice. We examined the impact and equity of this scheme on LARC uptake and abortions. METHODS AND FINDINGS: We examined records of 3,281,667 women aged 13 to 54 years registered with a primary care clinic in Britain (England, Wales, and Scotland) using Clinical Practice Research Datalink (CPRD) from 2004/2005 to 2013/2014. We used interrupted time series (ITS) analysis to examine trends in annual LARC and non-LARC hormonal contraception (NLHC) uptake and abortion rates, stratified by age and deprivation groups, before and after the P4P was introduced in 2009/2010. Between 2004/2005 and 2013/2014, crude LARC uptake rates increased by 32.0% from 29.6 per 1,000 women to 39.0 per 1,000 women, compared with 18.0% decrease in NLHC uptake. LARC uptake among women of all ages increased immediately after the P4P with step change of 5.36 per 1,000 women (all values are per 1,000 women unless stated, 95% CI 5.26-5.45, p < 0.001). Women aged 20 to 24 years had the largest step change (8.40, 8.34-8.47, p < 0.001) and sustained trend increase (3.14, 3.08-3.19, p < 0.001) compared with other age groups. NLHC uptake fell in all women with a step change of -22.8 (-24.5 to -21.2, p < 0.001), largely due to fall in combined hormonal contraception (CHC; -15.0, -15.5 to -14.5, p < 0.001). Abortion rates in all women fell immediately after the P4P with a step change of -2.28 (-2.98 to -1.57, p = 0.002) and sustained decrease in trend of -0.88 (-1.12 to -0.63, p < 0.001). The largest falls occurred in women aged 13 to 19 years (step change -5.04, -7.56 to -2.51, p = 0.011), women aged 20 to 24 years (step change -4.52, -7.48 to -1.57, p = 0.030), and women from the most deprived group (step change -4.40, -6.89 to -1.91, p = 0.018). We estimate that by 2013/2014, the P4P scheme resulted in an additional 4.53 LARC prescriptions per 1,000 women (relative increase of 13.4%) more than would have been expected without the scheme. There was a concurrent absolute reduction of -5.31 abortions per 1,000 women, or -38.3% relative reduction. Despite universal coverage of healthcare, some women might have obtained contraception elsewhere or had abortion procedure that was not recorded on CPRD. Other policies aiming to increase LARC use or reduce unplanned pregnancies around the same time could also explain the findings. CONCLUSIONS: In this study, we found that LARC uptake increased and abortions fell in the period after the P4P scheme in British primary care, with additional impact for young women aged 20-24 years and those from deprived backgrounds.

Projecting the fiscal impact of South Africa's contraceptive needs: Scaling up family planning post 2020.

BACKGROUND: Evidence-informed priority setting is vital to improved investment in public health interventions. This is particularly important as South Africa (SA) makes the shift to universal health coverage and institution of National Health Insurance. OBJECTIVES: To measure the financial impact of increasing the demand for modern contraceptive methods in the SA public health sector. We estimated the total cost of providing contraceptives, and specifically the budgetary impact of premature removals of long-acting reversible contraceptives. METHODS: We created a deterministic model in Microsoft Excel to estimate the costs of contraception provision over a 5-year time horizon (2018 - 2023) from a healthcare provider perspective. Only direct costs of service provision were considered, including drugs, supplies and personnel time. Costs were not discounted owing to the short time horizon. Scenario analyses were conducted to test uncertainty. RESULTS: The base-case cost of current contraceptive use in 2018 was estimated to be ZAR1.64 billion (ZAR29 per capita). Injectable contraceptives accounted for ~47% of total costs. To meet the total demand for family planning, SA would have to spend ~30% more than the estimate for current contraceptive use. In the year 2023, the 'current use' of modern contraceptives would increase to ZAR2.2 billion, and fulfilling the total demand for family planning would require ZAR2.9 billion. The base-case cost of implantable contraceptives was estimated at ZAR54 million. Assuming a normal removal rate, the use of implants is projected to increase by 20% during the 5-year period between 2019 and 2023, with an estimated 46% increase in costs. The cost of early removal of Implanon NXT is estimated at ZAR75 million, with total contraception costs estimated at ZAR102 million in 2019, compared with ZAR56 million when a normal removal rate is applied. CONCLUSIONS: The costs of scaling up modern contraceptives in SA are substantial. Early and premature removals of implantable contraceptives are costly to the nation and must be minimised. The government should consider conducting appropriate health technology assessments to inform the introduction of new public health interventions as SA makes the shift to universal health coverage by means of National Health Insurance.

Family planning in adolescents.

PURPOSE OF REVIEW: As politics continue to shape contraception and abortion care, providers have a responsibility to address the specific needs of the adolescent patient. Here we review the current literature on contraception and abortion in adolescents. RECENT FINDINGS: Shared decision-making among patients, parents, and providers is the cornerstone of successful adolescent family planning. Providers should be aware of local state regulations related to consent in minors. When provided directive and noncoercive contraception counseling at no cost, adolescents are motivated and effective decision-makers in their care. Long-acting reversible contraceptives should be offered as the first-line method of contraception in adolescents. SUMMARY: Family planning in adolescents presents unique challenges to obstetrician-gynecologists. Improved access to contraception and abortion services is significantly lowering unintended pregnancies rates in adolescents, but more data assessing the effectiveness of interventions in marginalized communities are needed.

Mobile Helpline and Reversible Contraception: Lessons From a Controlled Before-and-After Study in Rural India.

BACKGROUND: Researchers and activists have expressed concerns over the lack of availability and nonuse of reversible, modern, contraceptive methods in India for decades. New attempts to increase access, availability, and acceptance of reversible contraceptives need to be developed, instead of relying solely on female sterilization. Mobile health (mHealth) initiatives may offer one way to serve underprivileged populations who face challenges in sexual and reproductive health (SRH) in countries such as India. OBJECTIVE: This study aimed to examine the outcome of an mHealth intervention for enhancing knowledge of, and practices related to, reversible contraceptives in rural Western India. METHODS: We implemented a nonrandomized controlled trial (before-and-after study in an intervention area and a control area) in the Indian state of Maharashtra. The intervention in this case was a mobile-based SRH helpline provided by a nongovernmental organization (NGO). Baseline and follow-up surveys were carried out in two government-run primary health center areas, one each in the intervention and control area, and 405 respondents were surveyed in the two rounds. An interview-based structured questionnaire suitable for a low-literacy environment was used to collect data. The effect of the intervention was estimated using logistic regression, adjusted for gender, by calculating robust standard errors to take into account the clustering of individuals by the area (intervention or control). In each regression model, the effect of intervention was estimated by including a term for interaction between the intervention area and the period before and after the intervention. The exponent of the regression coefficient of the interaction term corresponding to the period after the intervention, along with the 95% CI, is reported here. The odds ratio for the control village multiplied by this exponent gives the odds ratio for the intervention village. Calls received in the intervention were recorded and their topics analyzed. RESULTS: The current use of reversible contraception (18% increase in intervention area vs 2% increase in control area; 95% CI) has seen changes. The proportion of respondents who had heard of contraception methods from an NGO rose in the intervention area by 23% whereas it decreased in the control area by 1% (95% CI). However, the general level of awareness of reversible contraception, shown by the first contraceptive method that came to respondents' mind, did not improve. Demand for wider SRH information beyond contraception was high. Men and adolescents, in addition to married women, made use of the helpline. CONCLUSIONS: A mobile helpline that one can confidentially approach at a time most convenient to the client can help provide necessary information and support to those who need reversible contraception or other sexual health information. Services that integrate mHealth in a context-sensitive way to other face-to-face health care services add value to SRH services in rural India.

Increase in Contraceptive Counseling by Primary Care Clinicians After Implementation of One Key Question® at an Urban Community Health Center.

Introduction To provide quality family planning services and reduce racial and socioeconomic disparities in unintended pregnancy and pregnancy outcomes, primary care clinicians should routinely assess women's reproductive health needs and provide patient-centered contraceptive and preconception counseling. One Key Question® asks women if they would like to become pregnant in the next year and prompts clinicians to provide counseling appropriate to each patient. We conducted a pilot study to assess if implementing One Key Question® in the Electronic Medical Record (EMR) of an urban community health center, coupled with brief clinician training, would increase rates of contraceptive and preconception counseling. Methods We incorporated One Key Question® into a new EMR form and provided a brief training to primary care clinicians on reproductive life plan assessment, preconception counseling, and contraception. We surveyed women patients, ages 18-49, after their visit and compared pre- vsersus post-intervention rates of patient-reported contraceptive and preconception counseling. Results After One Key Question® was introduced in the clinic EMR and clinicians underwent brief training on its use, patients reported significantly higher rates of their clinician counseling them about contraception (52% vs. 76%, p = 0.040) and recommending a long-acting reversible contraceptive (LARC) method (10% vs. 32%, p = 0.035). There were no significant changes in preconception counseling. Discussion After EMR integration of One Key Question® coupled with brief clinician training, rates of contraceptive counseling and LARC recommendations increased in this community health center pilot study. Future research should compare One Key Question® to standard care in a prospective randomized trial.

Trends, patterns and determinants of long-acting reversible methods of contraception among women in sub-Saharan Africa.

BACKGROUND: Method-specific contraceptive prevalence varies widely globally, as huge variations exist in the use of different types of contraception, with short-term methods being the most common methods in sub-Saharan Africa (SSA). Evidence is scanty on the trends, patterns and determinants of long-acting reversible contraceptive (LARC) methods in SSA. This study aimed to address this knowledge gap. METHODS: Using a pseudo longitudinal research design and descriptive and inferential statistics, we analysed Demographic and Health Survey data of eight countries selected on the basis of contraceptive prevalence rates across SSA. Multinomial logistic regression modelling was used to tease out the predictors of the uptake of LARC methods in the selected countries. RESULTS: Findings exhibit a steady but slow upward trend in LARC methods across selected countries, as a marginal increase was recorded in LARC uptake over a 10-year period in many of the selected countries. Results established significant predictors of LARC methods uptake, including fertility-related characteristics, age, level of education, work status, wealth index and exposure to mass media. This study underscored the need to address various barriers to the uptake of LARC methods in SSA. It is recommended that governments at different levels undertake to cover the costs of LARC methods in order to increase access and uptake.

Contextual influences on the choice of long-acting reversible and permanent contraception in Ethiopia: A multilevel analysis.

BACKGROUND: Long acting reversible and permanent contraception (LARPs) offer promising opportunities for addressing the high and growing unmet need for modern contraception and helps to reduce unintended pregnancies and abortion rates in sub-Saharan Africa (SSA). This study examines the contextual factors that influence the use of long acting reversible and permanent contraception among married and fecund women in Ethiopia. METHOD: We use data from the 2016 Ethiopian Demographic and Health Survey to examine the contextual factors that influence choice of long acting reversible and permanent contraception among married, non-pregnant and fecund women. The DHS collects detailed information on individual and household characteristics, contraception, and related reproductive behaviors from women of reproductive age. In addition, we created cluster level variables by aggregating individual level data to the cluster level. Analysis was done using a two-level multilevel logistic regression with data from 6994 married (weighted = 7352) women residing in 642 clusters (communities). RESULTS: In 2016, 12% of married, non-pregnant and 'fecund' women were using long-acting reversible and permanent methods of contraception in Ethiopia. A higher proportion of women with secondary and above education (17.6%), urban residents (19.7%), in the richest wealth quintile (18.3%) and in paid employment (18.3%) were using LARP methods compared to their counterparts. Regression analysis showed that community level variables such as women's empowerment, access to family planning information and services, region of residence and knowledge of methods were significantly associated with use of LARP methods. Age, wealth status, employment status and women's fertility preferences were among the individual and household level variables associated with choice of LARP methods. With regards to age, the odds of using LARP methods was significantly lower among adolescents (OR, 0.53; 95% CI, 0.32-0.85) and women over the age of 40 (OR, 0.63; 95% CI, 0.44-0.90) compared to women in their 20's. CONCLUSION: The findings of this study indicate that the demand for long-acting reversible and permanent contraception is influenced not only by women's individual and household characteristics but also by the community's level of women's empowerment, socio-economic development, as well as access and exposure to family planning information and services. Thus, improving knowledge of long-acting reversible and permanent methods, improving women's decision making autonomy and upgrading the capacity and skills of health workers particularly the midlevel providers and community health extension workers on the provision of LARP methods and rights-based approach is important to improve the uptake of LARP methods.

Long-acting Reversible Contraception (LARC) Provision by Family Physicians: Low But on the Rise.

Although the fraction of family physicians (FPs) providing Long Acting Reversible Contraceptive (LARC) services increased between 2014 and 2017, the most recent estimates show that less than a quarter of family physicians include provision of LARC in their practice. Increasing the number of FPs providing LARC will help increase patients' access to the most effective forms of birth control currently available.

Changes in the use of effective and long-acting reversible contraception in Vietnam.

OBJECTIVES: To calculate the prevalence and identify correlates of unmet need for contraception and to assess whether prevalence of use of effective contraception and long-acting reversible contraception (LARC) has changed over time among married or cohabiting, reproductive-age women in Vietnam. METHODS: Study population was drawn from nationally representative Multiple Indicator Cluster Surveys conducted in 2000, 2006, 2011 and 2014. Unmet need for contraception was defined as occurring when a fecund, married or cohabiting woman is not using any method of contraception but either does not want children or wants to delay birth for at least 1 year or until marriage. Following the ranking of method effectiveness by the Centers for Disease Control and Prevention, we defined "effective contraception" as implant, intrauterine device, male and female sterilization, injectable, pill, patch, ring or diaphragm. We used multivariable logistic regression to identify correlates of unmet need for contraception in 2014 and Cochran-Armitage trend tests to assess changes in effective contraception and LARC use from 2000 to 2014. All analyses used survey weights to account for the complex sampling design. RESULTS: In 2014, 4.3% of married or cohabiting, reproductive-age women had unmet need for contraception. Multivariable analysis showed that age, education and number of children ever born were statistically significant correlates of unmet need for contraception. Use of effective contraception statistically significantly declined from 53.0% in 2000 to 45.7% in 2014 (p<.0001). Similarly, LARC declined from 39.6% in 2000 to 30.0% in 2014 (p<.0001). After adjusting for age, education, residence and having at least one son, these secular trends remained. CONCLUSION: Findings indicate that effective contraception and LARC use have decreased among married or cohabiting women of reproductive age in Vietnam. Correlates of unmet need for contraception should be used to inform interventions to prevent unintended pregnancy. IMPLICATIONS: Although the prevalence of unmet need for contraception was low (4.3%) in 2014, the use of effective contraception and long-acting reversible contraception declined among reproductive-age, married or cohabiting women in Vietnam from 2000 to 2014. This finding is particularly striking given the economic growth in the nation during this time frame.

Is Long-Acting Reversible Contraceptive Use Increasing? Assessing Trends Among U.S. College Women, 2008-2013.

Objective To assess LARC use trends among college women (18-24 years) and identify groups that have increased LARC use. Methods Data were extracted from the National College Health Assessment-II (NCHA-II) fall 2008-2013 surveys. Logistic regression statistics were used to assess LARC use. Results Although LARC use increased from 2008 to 2013 (aOR = 2.62; 95% CI 2.23-3.07), less than half of the sample (44%) reported using contraception at last vaginal sex. Only 2.5% of college women in this study reported using a LARC method; of LARC users, 90% reported using an intrauterine device. Nearly all sociodemographic factors were significantly associated with increases in LARC use including: age, sexual orientation, and insurance status. Conclusions LARC use significantly increased among college women. However, less effective methods such as condoms and short-acting reversible contraceptives are used more frequently. Promoting LARC use for women who desire to effectively prevent pregnancy can reduce unintended pregnancy and improve health outcomes for women while in college. Future work should examine the importance of individual and lifestyle factors that influence college women's decision to choose a LARC method and seek to eliminate barriers to college women choosing a contraceptive method they believe works best for them.

Temporal Trends in the Uptake and Continuation of the Etonogestrel Implant in a Large Private Practice Setting.

OBJECTIVE: To assess temporal trends in the uptake and continuation of the etonogestrel subdermal implant in a large private practice setting. METHODS: This was a retrospective cohort study based on billing records from a large multispecialty private practice in Las Vegas, Nevada. We looked at women of all ages seeking long-acting reversible contraception (LARC) between January 1, 2013, and December 31, 2016. The main outcome measure was uptake of the etonogestrel subdermal implant, expressed as a fraction of all insertions of LARC across four calendar years (2013-2016). The Kaplan-Meier method was used to estimate 12-month continuation stratified by year of insertion. RESULTS: There were 3477 total LARC insertions across the 4-year study period. In unadjusted analyses, the uptake of the etonogestrel implant increased from 3.0% of LARC insertions in 2013 to 9% in 2016 among women aged 30 years and older. For women younger than 30 years, the uptake of the implant stayed stable from 2013 to 2015 (22.8%, 21.7%, and 22.4%, respectively), but increased to 30.9% in 2016. We modeled the uptake of the implant as a function of year of insertion adjusted for age (continuous) and insurance status (private vs. Medicaid), and we stratified the models by age (younger than 30 years, 30 years, and older than 30 years). The positive association between year of insertion and uptake of the implant was significantly stronger for women aged 30 years and older, compared to women younger than 30 years. There was a progressive decrease in the 12-month continuation of implant from 2013 (95.7%) to 2015 (57.7%). CONCLUSIONS: In this large private practice setting, among women aged 30 years and older, we observed a threefold increase in the uptake of the subdermal implant from 2013 to 2016. We also observed a significant decrease in the 12-month continuation of the implant over time. Further studies of implant uptake and continuation in the private practice setting are needed.

Trends in contraceptive use according to HIV status among privately insured women in the United States.

BACKGROUND: There is limited information on the patterns and trends of contraceptive use among women living with HIV, compared with noninfected women in the United States. Further, little is known about whether antiretroviral therapy correlates with contraceptive use. Such information is needed to help identify potential gaps in care and to enhance unintended pregnancy prevention efforts. OBJECTIVE: We sought to compare contraceptive method use among HIV-infected and noninfected privately insured women in the United States, and to evaluate the association between antiretroviral therapy use and contraceptive method use. STUDY DESIGN: We used a large US nationwide health care claims database to identify girls and women ages 15-44 years with prescription drug coverage. We used diagnosis, procedure, and National Drug Codes to assess female sterilization and reversible prescription contraception use in 2008 and 2014 among women continuously enrolled in the database during 2003 through 2008 or 2009 through 2014, respectively. Women with no codes were classified as using no method; these may have included women using nonprescription methods, such as condoms. We calculated prevalence of contraceptive use by HIV infection status, and by use of antiretroviral therapy among those with HIV. We used multivariable polytomous logistic regression to calculate unadjusted and adjusted odds ratios and 95% confidence intervals for female sterilization, long-acting reversible contraception, and short-acting hormonal contraception compared to no method. RESULTS: While contraceptive use increased among HIV-infected and noninfected women from 2008 through 2014, in both years, a lower proportion of HIV-infected women used prescription contraceptive methods (2008: 17.5%; 2014: 28.9%, compared with noninfected women (2008: 28.8%; 2014: 39.8%, P < .001 for both). Controlling for demographics, chronic medical conditions, pregnancy history, and cohort year, HIV-infected women compared to HIV-noninfected women had lower odds of using long-acting reversible contraception (adjusted odds ratio, 0.67; 95% confidence interval, 0.52-0.86 compared to no method) or short-acting hormonal contraception method (adjusted odds ratio, 0.59; 95% confidence interval, 0.50-0.70 compared to no method). In 2014, HIV-infected women using antiretroviral therapy were significantly more likely to use no method (76.8% vs 64.1%), and significantly less likely to use short-acting hormonal contraception (11.0% vs 22.7%) compared to HIV-infected women not using antiretroviral therapy. Those receiving antiretroviral therapy had lower odds of using short-acting hormonal contraception compared to no method (adjusted odds ratio, 0.45; 95% confidence interval, 0.32-0.63). There was no significant difference in female sterilization by HIV status or antiretroviral therapy use. CONCLUSION: Despite the safety of reversible contraceptives for women with HIV, use of prescription contraception continues to be lower among privately insured HIV-infected women compared to noninfected women, particularly among those receiving antiretroviral therapy.

Trends of contraception use among married reproductive age women: Tehran lipid and glucose cohort study 2002-2011.

OBJECTIVES: This study aimed to examine the trends of contraception use among married reproductive age women in Tehran Lipid and Glucose study between 2002 and 2011. METHODS: This analysis investigated a proportion of women users and non-users of family planning, using data from 10year population-based Tehran Lipid Glucose Study from surveys conducted in 2002, 2005, 2008, and 2011. Of the 6813, 6993, 7077, and 6789 women in the four phases mentioned, 34.1%, 33.9%, 33.5% and 35% of participants in each phase preferred to use contraception. Number of participants studied were 2506 women in 2002, 2529 women in 2005, 2594 women in 2008 and 2525 women in 2011. RESULTS: Types of methods and patterns of change in contraception differed across time. The percentage of women using traditional methods increased significantly from 25.7% in 2002 to 34.6% in 2011 (p value for trend=0.001). Accordingly, modern contraception use showed a reverse trend. From 2002 to 2011, 61.4%, 61%, 57.7%, and 51% of married women reported currently using various modern contraceptives, respectively (p value for trend=0.001). The proportion of users relying on condoms showed a significant increase during this decade, being 10.9% in 2002, 15.2% in 2005, 20% in 2008 and 21.9% in 2011. The prevalence of non-users for contraception was generally low; 12.7%, 8.2%, 8% and 14.3%, respectively from 2002 to 2011, but increased significantly across time (p=0.005) CONCLUSION: Relying on less effective contraceptive methods has increased rapidly among women in the Tehran Lipid and Glucose cohort study, a trend that could be a warning to policy makers about the possibility of higher unsafe abortion and maternal mortality/morbidity rates in the near future.

Trends in Long-Acting Reversible Contraception Use in Adolescents and Young Adults: New Estimates Accounting for Sexual Experience.

PURPOSE: The purposes of the analysis were to compare long-acting reversible contraception (LARC) use estimates that include all reproductive age women with estimates that are limited to women at risk for unintended pregnancy and to examine trends for adolescents (15-19 years) and young adults (20-24 years). METHODS: Using the 2006-2010 and 2011-2013 National Surveys of Family Growth, we compared LARC estimates for all women with estimates limited to women at risk for unintended pregnancy (those who were sexually experienced, and neither pregnant, seeking pregnancy, postpartum or infecund). We used t tests to detect differences according to the population included and to evaluate trends for adolescents and young adults. RESULTS: Among adolescents and young adults, 56% and 14%, respectively, have never had vaginal intercourse, versus 1%-4% for women aged 25-44 years. Given the high percentage of adolescents and young adults who never had vaginal intercourse, LARC estimates were higher for these age groups (p < .05), but not for women aged 25-44 years, when limited to those at risk for unintended pregnancy. Among adolescents at risk, the increase in LARC use from 2006-2008 (1.1%) to 2008-2010 (3.6%) was not significant (p = .07), and no further increase occurred from 2008-2010 to 2011-2013 (3.2%); by contrast, among young adults at risk, LARC use increased from 2006-2008 (3.2%) to 2008-2010 (6.9%) and from 2008-2010 to 2011-2013 (11.1%). CONCLUSIONS: Because many adolescents and young adult women have never had vaginal intercourse, for these groups, including all women underestimates LARC use for pregnancy prevention. Among young adults, use of LARC for pregnancy prevention has increased but remains low among adolescents.
