Project description:Background: Women living with HIV have the right to choose whether, when and how many children to have. Access to antiretroviral therapy (ART) and contraceptives, including implants, continues to increase due to a multitude of efforts. In Kenya, 4.8% of adults are living with HIV, and in 2017, 54% were receiving an efavirenz-based ART regimen. Meanwhile, 16.1% of all Kenyan married (and 10.4% of unmarried) women used implants. Studies have reported drug interactions leading to contraceptive failures among implant users on ART. This retrospective record review aimed to determine unintentional pregnancy rates among women 15-49 years of age, living with HIV and concurrently using implants and ART in western Kenya between 2011 and 2015. Methods: We reviewed charts of women with more than three months of concurrent implant and ART use. Implant failure was defined as implant removal due to pregnancy or birth after implant placement, but prior to scheduled removal date. The incidence of unintended pregnancy was calculated by woman-years at risk, assuming a constant rate. Results: Data from 1,152 charts were abstracted, resulting in 1,190 implant and ART combinations. We identified 115 pregnancies, yielding a pregnancy incidence rate of 6.32 (5.27-7.59), with 9.26 among ETG and 4.74 among LNG implant users, respectively. No pregnancies were recorded among women on non-NNRTI-based regimens, whereas pregnancy rates for efavirenz and nevirapine-containing regimens were similar, at 6.41 (4.70-8.73) and 6.44 (5.13-8.07), respectively. Conclusions: Our findings highlight the implications of drug interaction on women's choices for contraception.

Project description:ObjectiveTo examine the relationship between pregnancy coercion and partner knowledge of contraceptive use.Study designCross-sectional Performance Monitoring for Action-Ethiopia data were collected in October-November 2019 from a nationally representative sample of women ages 15 to 49. The analytical sample (n = 2,469) included partnered women using contraception in the past year. We used multinomial logistic regression to examine associations between past-year pregnancy coercion (none, less severe, more severe) and partner knowledge/couple discussion of contraceptive use (overt use with couple discussion before method initiation (reference group), overt use with discussion after method initiation, and covert use of contraception).ResultsMost women reported their partner knew they were using contraception and had discussed use prior to method initiation (1,837/2,469, 75%); 16% used overtly and discussed use after method initiation, and 7% used contraception covertly. The proportion of covert users increased with pregnancy coercion severity (4%none, 14%less severe, 31%more severe), as did the proportion of overt users who delayed couple contraceptive discussions, (14%none, 23%less severe, 26% more severe); however, overt use with couple discussion before method initiation decreased with pregnancy coercion severity (79%none, 60%less severe, 40%more severe). The risk of covert use among women experiencing less severe pregnancy coercion was four times greater than women who experienced no pregnancy coercion (adjusted relative risk ratio, (aRRR) = 3.95, 95% confidence interval (CI) 2.20-7.09) and ten times greater for women who experienced the most severe pregnancy coercion (aRRR = 10.42, 95% CI 6.14-17.71). The risk of overt use with delayed couple discussion also increased two-fold among women who experienced pregnancy coercion compared to those who did not (less severe aRRR = 2.05, 95% CI 1.39-2.99; more severe aRRR = 2.89, 95% CI 1.76-4.73).ConclusionWhen experiencing pregnancy coercion, women may avoid or delay contraceptive conversations with their partners. Increased pregnancy coercion severity has the greatest association with covert use and couple contraceptive discussions.ImplicationsThe presence and timing of couple discussions about contraception are critical for ensuring safety for women experiencing pregnancy coercion. Screening for pregnancy coercion must be included within contraceptive counseling so that women can choose methods that maximize their reproductive autonomy.

Project description:BackgroundPreventing unintended pregnancy is critical for women living with HIV (WLWH) to safely achieve their reproductive goals. Family planning services should support WLWH at risk of repeat unintended pregnancies. We examined the relationship between unintended pregnancy and subsequent contraception use among WLWH in Uganda.Study designThis was a retrospective analysis of data from a longitudinal cohort of individuals initiating antiretroviral therapy (ART), restricted to women with pregnancy (confirmed via urine β-hcg testing) between 2011-2013. The exposure of interest was intended vs unintended pregnancy, and the outcome was self-report of modern contraceptive use (hormonal methods, intrauterine device, sterilization, and/or consistent condom use) at 12 (range 6-18) months post-partum. A log-binomial model was used to estimate relative risks of modern contraceptive use post-partum based on intent of the index pregnancy, adjusted for age, socioeconomic status, education, relationship and HIV status of pregnancy partner, contraceptive use prior to pregnancy, years since HIV diagnosis, ART regimen, and CD4 cell count.ResultsAmong 455 women, 110 women reported 110 incident pregnancies with report on intent. Women had a baseline median age of 29 years, baseline CD4 count 403 cells/mm3, and were living with HIV for 3.8 years. Fifty pregnancies (45%) were reported as unintended and 60 (55%) as intended. Postpartum, 64% of women with unintended and 51% with intended pregnancy reported modern contraception (p = 0.24). In adjusted models, there was no association between pregnancy intent and post-partum contraception. However, contraceptive use prior to the referent pregnancy was positively associated with post-partum contraceptive use (aRR 1.97 (95% CI 1.12-3.48, p = 0.02), while higher baseline CD4 cell count was associated with lower post-partum contraceptive use (aRR 0.95, 95% CI 0.90-0.99, p = 0.02).ConclusionsAlmost half of incident pregnancies among WLWH in this cohort were unintended. Experiencing an unintended pregnancy was not associated with post-partum contraceptive use. Creative strategies to support contraceptive uptake for birth spacing and prevention of unintended pregnancies in the post-partum period are needed.

Project description:BackgroundLittle is known about contraceptive care for the growing population of women veterans who receive care in the Veterans Administration (VA) healthcare system.ObjectiveTo determine rates of contraceptive use, unmet need for prescription contraception, and unintended pregnancy among reproductive-aged women veterans.Design and participantsWe conducted a cross-sectional, telephone-based survey with a national sample of 2302 women veterans aged 18-44 years who had received primary care in the VA within the prior 12 months.Main measuresDescriptive statistics were used to estimate rates of contraceptive use and unintended pregnancy in the total sample. We also estimated the unmet need for prescription contraception in the subset of women at risk for unintended pregnancy. For comparison, we calculated age-adjusted US population estimates using data from the 2011-2013 National Survey of Family Growth (NSFG).Key resultsOverall, 62% of women veterans reported current use of contraception, compared to 68% of women in the age-adjusted US population. Among the subset of women at risk for unintended pregnancy, 27% of women veterans were not using prescription contraception, compared to 30% in the US population. Among women veterans, the annual unintended pregnancy rate was 26 per 1000 women; 37% of pregnancies were unintended. In the age-adjusted US population, the annual rate of unintended pregnancy was 34 per 1000 women; 35% of pregnancies were unintended.ConclusionsWhile rates of contraceptive use, unmet contraceptive need, and unintended pregnancy among women veterans served by the VA are similar to those in the US population, these rates are suboptimal in both populations, with over a quarter of women who are at risk for unintended pregnancy not using prescription contraception, and unintended pregnancies accounting for over a third of all pregnancies. Efforts to improve contraceptive service delivery and to reduce unintended pregnancy are needed for both veteran and civilian populations.

Project description:ObjectiveTo evaluate the association between marijuana use and a composite adverse pregnancy outcome using biological sampling.DesignRetrospective cohort study.SettingSingle tertiary center.PopulationYoung women (13-22 years old) with singleton, non-anomalous pregnancies delivered from September 2011 to May 2017.MethodsExposure was defined as marijuana detected on universal urine toxicology testing or by self-report. Multivariable logistic regression modelling was used to estimate the effect of any marijuana use on the primary composite outcome. The effect of marijuana exposure was also estimated for self-reported use, toxicology-detected use, and multiple use detected by toxicology.Main outcome measureThe primary composite outcome included spontaneous preterm birth, hypertensive disorders of pregnancy, stillbirth, or small for gestational age.ResultsOf 1206 pregnant young women, 17.5% (n = 211) used marijuana. Among the women who used marijuana, 8.5% (n = 18) were identified by self-report alone, 63% (n = 133) by urine toxicology alone, and 28.4% (n = 60) by both. Urine toxicology testing results were available for 1092 (90.5%) births. The composite outcome occurred more frequently in pregnancies exposed to marijuana (46 versus 34%, P < 0.001). This remained significant after adjusting for race/ethnicity and tobacco in the multivariable model (adjusted OR 1.50, 95% CI 1.09-2.05). When marijuana exposure was defined by self-report only, the association with adverse pregnancy outcome became non-significant (adjusted OR 1.01, 95% CI 0.62-1.64).ConclusionIn a population of young women with nearly universal biological sampling, marijuana exposure was associated with adverse pregnancy outcomes. The heterogeneity of findings in existing studies evaluating the impact of marijuana on mothers and neonates may result from the incomplete ascertainment of exposure.Tweetable abstractMarijuana use, as detected by universal urine testing, was associated with a composite adverse pregnancy outcome among young mothers.

Project description:This retrospective cohort study attempts to investigate pregnancy complications and adverse pregnancy outcomes in women of advanced maternal age (AMA). Data were extracted from electronic medical records system at West China Second University Hospital of Sichuan University from January 2013 to July 2016. The study cohort consisted 8 subgroups of women on 4 different age levels (20-29 years, 30-34 years, 35-39 years and ≥40 years) and 2 different parities (primiparity and multiparity). In the study period, 38811 women gave birth at our hospital, a randomized block was used to include 2800 women of singleton pregnancy >28 gestational weeks, with 350 patients in each subgroup. Maternal complications and fetal outcomes were collected and defined according to relevant guidelines. Confounding factors representing maternal demographic characteristics were identified from previous studies and analysed in multivariate analysis. There was an increasing trend for the risks of adverse pregnancy outcomes with increasing age, especially in AMA groups. Our study showed that AMA, primiparity, maternal overweight or obesity, lower educational level and residence in rural area increased pregnancy complications and adverse fetal outcomes. Increased professional care as well as public concern is warranted.

Project description:BackgroundOpioid use has increased dramatically in North America. The safety of opioids in pregnancy is uncertain, but they are associated with several fetal abnormalities and contribute to rising rates of neonatal abstinence syndrome. We examined opioid use before and during pregnancy in a complete population-based cohort.MethodsWe examined opioid use in a cohort of all pregnant women in Manitoba, Canada, from 2001 to 2013. Opioid use was defined by prescriptions for opioids, converted to oral morphine equivalents (MEQ), during the 3 months before pregnancy and for each trimester. Given that the exposure per person may vary (because not all women complete all time periods), we determined a weighted number of pregnancies in each period.ResultsDuring the study period, 174 848 completed pregnancies were eligible for analysis (173 680 live births and 1168 stillbirths and intrauterine deaths), which represented a weighted value of 175?174 pregnancies. Among these pregnancies, 6.7% of the women filled opioid prescriptions in the 3 months before pregnancy. Use declined to 4.2% during the first trimester and further declined to 3.0% and 2.9% in the second and third trimesters, respectively. Over the study period, there was a modest increase in opioid use overall (from 7.3% to 7.7%). MEQ did not decline during pregnancy, and the mean MEQ increased significantly over the study period (from 284 mg to 1218 mg). Prescriptions for codeine were filled by 96.9% of the users, accounting for 66.2% of MEQ.InterpretationAlthough many of the women using opioids before pregnancy discontinued or reduced use of these drugs during pregnancy, the volume of opioids consumed by those who continued opioid use did not decline during pregnancy. The increasing dosage and increased use of higher-potency opioids by pregnant women highlights the need for continued evaluation of and education about the benefits and risks of this practice.

Project description:ObjectiveTo completely and quantifiably determine the effect of systemic lupus erythematosus (SLE) on pregnancy outcomes in a Chinese cohort.DesignA retrospective cohort study.SettingData were collected at a tertiary medical centre located in Shanghai, China, from September 2011 to May 2017.ParticipantsWe assigned 338 pregnant women with SLE to the study cohort and 1014 randomly selected pregnant women without SLE (three for every woman with SLE) to a comparison cohort. The relevant medical records of all pregnant women were retrospectively reviewed. Cases of multiple pregnancy and cases in which an artificial abortion was performed for personal reasons were excluded.Primary and secondary outcome measuresMaternal and fetal outcomes were primary outcomes, and management of antenatal care was the secondary outcome.ResultsThe risks of pregnancy-induced hypertension (OR 2.68, 95% CI 1.75 to 4.09), pre-eclampsia (OR 3.13, 95% CI 1.95 to 5.03) and premature rupture of membranes (OR 2.53, 95% CI 1.46 to 4.40) were significantly different between women with and without SLE. Gestational diabetes was negatively associated with SLE in pregnant women (OR 0.49, 95% CI 0.28 to 0.85). Pregnant women with SLE displayed significantly higher rates of fetal loss (OR 10.23, 95% CI 5.08 to 20.59), including spontaneous abortion (OR 4.42, 95% CI 1.52 to 12.80), therapeutic abortion (OR 16.57, 95% CI 5.80 to 47.35) and stillbirth (OR 13.25, 95% CI 1.49 to 118.11), and a higher risk of preterm birth (OR 3.15, 95% CI 2.21 to 4.50), intrauterine growth restriction (OR 2.20, 95% CI 1.35 to 3.58), a child who was small for the gestational age (OR 1.86, 95% CI 1.11 to 3.13), a caesarean section (OR 4.73, 95% CI 3.30 to 6.80) or a neonatal intensive care unit admission (OR 3.48, 95% CI 2.21 to 5.48) than women in the non-SLE population after adjusting for confounding factors.ConclusionsIn this study, SLE significantly increased the risk of adverse pregnancy outcomes. Therefore, a preconception assessment and close antenatal monitoring by both rheumatologists and obstetricians should be performed in pregnant women with SLE.

Project description:Recent HIV prevention trials required use of effective contraceptive methods to fulfill eligibility for enrollment. We compared pregnancy rates in a subset of participants enrolled in the Microbicide Trials Network protocol (MTN-003), a randomized trial of chemoprophylaxis to prevent HIV acquisition among women aged 18-45 years who initiated depot medroxyprogesterone acetate (DMPA) or combined oral contraceptives (COCs) at enrollment, relative to those already using DMPA or COCs.Data were analyzed from MTN-003 participants from Uganda. Before enrollment, information on contraceptive type and initiation date was obtained. Urine pregnancy tests were performed at monthly follow-up visits. Cox proportional hazards models were used to compare pregnancy incidence among new users (initiated ?60 days before enrollment) and established users (initiated >60 days before enrollment).Of 322 women enrolled, 296 were COC or DMPA users, 82 (28%) were new users, and 214 (72%) were established users. Pregnancy incidence was higher among new contraceptive users compared to established users (20.70% vs. 10.55%; adjusted hazard ratio [HR]?=?1.66; 95% confidence interval [95% CI] 0.93-2.96). Among DMPA users, pregnancy incidence was 10.20% in new users versus 3.48% in established users (HR?=?2.56; 95% CI 0.86-7.65). Among new COC users, pregnancy incidence was 42.67% in new users versus 23.67% in established COC users (adjusted HR?=?1.74; 95% CI 0.87-3.48).New contraceptive users, regardless of method, at the Uganda MTN-003 site had an increased pregnancy risk compared to established users, which may be due to contraceptive initiation primarily for trial eligibility. New users may benefit from intensive contraceptive counseling and additional contraceptive options, including longer acting reversible contraceptives.

Project description:The objective of this study was to determine factors associated with modern contraceptive use and unintended pregnancy among young women and men in Accra, Ghana. From September-December 2013, we conducted a cross-sectional survey with 250 women and 100 men aged 18-24. We explored determinants of modern contraceptive use among males and females and unintended pregnancy among females. Descriptive statistics, chi-square tests, Fisher's exact tests, and multivariable logistic regression were used. Participants had an average of three lifetime sexual partners, and 91% had one current partner. Overall, 44% reported current modern contraceptive use. In multivariate modeling, modern contraceptive use was associated with higher education compared to primary (AORs 2.1-4.3); ever talking with someone about contraception (AOR 4.7); feeling unsupported by a healthcare provider for contraception (AOR 2.2); and not feeling at risk of unintended pregnancy (AOR 2.7). While ≥70% of participants recognized most contraceptive methods, awareness of some methods was lacking. Nearly all respondents (91%) felt at least one modern method was unsafe. Nearly half of all females (45%) reported their last pregnancy was unintended, and 63% of females and 58% of males felt at risk for future unintended pregnancy. Women were more likely to experience unintended pregnancy if they had ever given birth (AOR 6.7), their sexual debut was 8-14 years versus 20-24 years (AOR 3.4), or they had 3-4 lifetime sexual partners versus 1-2 (AOR 2.4). Targeted interventions are needed to improve understanding of the safety of modern contraceptive methods, increase awareness of long-acting methods, and consequently increase modern contraceptive access and use.
