RESUMEN

Introduction Through its National Family Planning Programme, India has been relentlessly working to decrease society's unmet contraception needs. The postpartum period is of paramount importance for addressing these contraceptive needs owing to alterations in fertility and coital behavior associated with childbirth. Depot medroxyprogesterone acetate (DMPA), a long-acting reversible contraceptive, is one of the safe options available in the early postpartum period. In this study, we aimed to evaluate its efficacy and acceptability among postpartum women delivering in Guru Gobind Singh Medical College and Hospital. Methodology We recruited 206 early postpartum women for the study. After thorough counseling and ensuring establishment of lactation, we administered DMPA 150mg by injection intramuscularly and repeated it at intervals of three months in willing patients. We then evaluated them for their symptoms, side effects, and lactation status using a predesigned proforma either during their follow-up visits or telephonically. Results We found DMPA to be 100% efficacious as an early postpartum contraceptive measure. The main reasons for acceptance were its ease of use, long-term effects of a single dose, and noninterference with lactation. However, the continuation rate for the second dose was only 18% in our study, highlighting the need for better counseling and improving awareness among our patients. Ninety-nine percent of our patients were satisfied with their lactation. Conclusion We found injectable DMPA used as a contraceptive in the immediate postpartum period to be a safe and effective alternate method with no deleterious effect on lactation and an acceptable side effect profile. However, more awareness programs are necessary to encourage women, especially those in low-resource areas, to continue using DMPA.

RESUMEN

OBJECTIVES: To evaluate medication abortion (MAB) outcomes for participants receiving intramuscular depot medroxyprogesterone acetate (DMPA) injections or subdermal etonogestrel implants concurrently with mifepristone compared to those who did not in a real-world setting. STUDY DESIGN: This retrospective cohort study included MAB patients from one Planned Parenthood health center in St. Paul, MN, between 2017 and 2019. We abstracted electronic health records and compared sociodemographic variables, clinical information, and treatment failure rates (primary outcome) between study groups with logistic regression (generating odds ratios [OR] and 95% confidence intervals [CI]). RESULTS: Among 7296 MAB participants, 224 (3.1%) received DMPA injections and 309 (4.2%) received etonogestrel implants concurrently with mifepristone; 141 (62.9%) and 200 (64.7%) completed follow-up respectively. From a random sample of 1000, 990 comparison participants met inclusion criteria; 704 (71.1%) completed follow-up. Fourteen (9.9%) DMPA participants (aOR 4.26, 95% CI 1.87-9.68, p < 0.001) and 6 (3.0%) etonogestrel implant participants (aOR 1.38, 95% CI 0.48-3.55, p = 0.522) required additional treatment to empty the uterus and/or had an ongoing pregnancy, each contrasted with 15 (2.1%) comparison patients (models adjusted for gestational duration, patient age, parity, and race). CONCLUSION: Although our study is limited by high rates of loss to follow-up, our analysis suggests that concurrent administration of DMPA with mifepristone may decrease MAB efficacy, while etonogestrel implant placement does not appear to alter MAB outcomes. These findings are overall consistent with prior literature and inform post-MAB contraception counseling. IMPLICATIONS: This retrospective cohort study reinforces prior randomized controlled trial findings that concurrent depot medroxyprogesterone acetate injection with mifepristone administration may decrease medication abortion efficacy. Conversely, concurrent etonogestrel contraceptive implant placement with mifepristone administration does not appear to decrease medication abortion efficacy. These findings inform post-abortion contraception counseling.

RESUMEN

Background: Choosing a contraceptive method is a pivotal decision for patients, whereas health care professionals (HCPs) face challenges in providing suitable recommendations. Adverse sexual effects often lead to dissatisfaction and discontinuation of contraceptives, underscoring the importance of thorough counseling and shared decision making between HCPs and patients. Objective: This article aims to investigate the relationship between contraceptive methods and female sexual function through a comprehensive review of available literature, emphasizing the importance of considering sexual health in contraceptive prescription and management. Methods: A systematic analysis of existing literature, incorporating studies utilizing validated sexual health questionnaires, was conducted to elucidate the intricate interplay between contraceptives and female sexual function. Results: The review encompasses various contraceptive methods, including combined hormonal contraceptives, progestin-only pills, depot medroxyprogesterone acetate, subdermal contraceptive implants, hormonal intrauterine devices, permanent sterilization, and barrier methods. Insights gleaned from the analysis shed light on the impact of these methods on female sexual health. Conclusion: Comprehensive understanding of the effects of contraceptives on female sexual function is crucial for both HCPs and patients. By integrating sexual health considerations into contraceptive surveillance, compliance can be improved, contraceptive efficacy optimized, and the risk of unwanted pregnancies minimized. This review underscores the significance of tailored counseling and shared decision making in contraceptive management, particularly for cisgender women.

RESUMEN

Introduction In India, one of the world's most populous and swiftly growing countries, it is crucial to prioritize the utilization of safe and effective contraception, as contraceptive strategies play a pivotal role in bolstering community health. It is widely acknowledged that ensuring appropriate timing and spacing of pregnancies is crucial for the well-being of reproductive, maternal, neonatal, child, and adolescent health. Adoption of reversible or spacing contraceptive methods can significantly enhance women's health outcomes by reducing the occurrence of undesired, closely timed, and mistimed pregnancies. Consequently, in response to the pressing need for dependable contraception in India, this study seeks to assess the acceptance, adherence, and side effects of the injectable contraceptive depot medroxyprogesterone acetate (DMPA) among its users. Methods This prospective observational study was done at the State Government Taluk Hospital in the Cuddalore District of Tamil Nadu from July 2022 to October 2022. A total of 40 women of reproductive age who opted for DMPA as their contraceptive method and met the inclusion criteria were recruited through a purposive sampling method. A structured questionnaire was used to collect the data. Results The majority of the participants were women aged 21-25 years (n=14; 35%). The participants were predominantly Hindu (n=39; 97.5%), and 35 (87.5%) had completed higher secondary education. All participants (n=40; 100%) resided in rural areas and the majority were homemakers. A significant proportion of the participants had two children (n=21; 52.5%), and all of them received information on DMPA primarily from health personnel. At the initial point of data collection, three-fourths of them took the first dose (n=13; 32.5%) and only a few took more than three doses (n=3; 7.5%). In the third month, the results showed a drop in DMPA use, which indicates a lower adherence particularly linked to side effects like irregular bleeding (n=15; 37.5%) and amenorrhea (n=9; 22.5%). Furthermore, 35 (87.5%) of the women chose DMPA for birth spacing due to its efficacy and convenience, with few initiating it during postpartum (n=4; 10%) and post-abortal (n=1; 2.5%) periods. The reasons for continuing DMPA use included efficacy (n=20; 50%), discreet usage (n=15; 37.5%), and curiosity (n=13; 32.5%). Half of the participants reported no side effects. The study identified associations between DMPA users and the number of living children and occupational status inferring that DMPA contraception is used for spacing births. Conclusion The results of this study imply that the use and adherence to injectable contraceptive DMPA need to be strengthened among rural women. Thus, the study suggests incorporating information, education, and communication strategies, to enhance awareness among rural women about injectable contraceptives.

RESUMEN

BACKGROUND: Robust information on relative effects of hormonal contraceptives on endogenous androgens is important for understanding beneficial and adverse effects, method choice and development of new methods. METHODS: In this ancillary study at the East London, South Africa site of the ECHO multicentre randomized trial, we compared effects of three contraceptive methods on serum androgen levels among contraceptive users aged 18 to 35 years. Participants were allocated by centrally-managed randomization to open label depot medroxyprogesterone acetate (DMPA-IM), copper intrauterine device (IUD) or levonorgestrel implant. The primary outcome was free testosterone at 6 months. RESULTS: We analysed stored baseline and 6-month serum samples in 398/615 participants (DMPA-IM 131/205, IUD 135/205 and implant 132/205). Median testosterone levels at baseline were DMPA-IM 0.82, IUD 0.9 and implant 0.87 nmol/L; at 6 months, DMPA 0.68 (lower than IUD, mean percentage difference 28.35, (p <  0.001), IUD 0.86 (unchanged) and implant 0.66, lower than IUD, mean percentage difference - 22.98, p <  0.001). Median SHBG levels at baseline were DMPA 52.4, IUD 50.5 and implant 55.75 nmol/L; at 6 months, DMPA 40.65, lower than IUD (mean percentage difference 21.19, p = 0.005), IUD 49.1 (unchanged), and implant 23.35 nmol/L, lower than IUD (mean percentage difference - 50.04, p <  0.001 and than DMPA (mean percentage difference - 39.45, p <  0.001). Free testosterone levels at baseline were DMPA 10, IUD 12 and implant 11 pmol/L; at 6 months, DMPA 11, less than IUD (mean percentage difference 13.53, p = 0.047), IUD 12 and implant 14, higher than IUD (mean percentage difference 14.15, p = 0.038) and than DMPA, (mean percentage difference 29.60, p < 0.001). CONCLUSIONS: This is the first randomized trial to show lower SHBG and higher free testosterone with the levonorgestrel implant than with DMPA, and contrasts with reports of increased SHBG with combined oral ethinyl estradiol/levonorgestrel use, and reduced androgens (and impaired sexual function) reported with the etonorgestrel implant. The higher free testosterone with the LNG implant might improve sexual function, mood and bone health as well as increasing side-effects such as acne and hirsutism, and is consistent with the greater sexual activity (with respect to multiple sex partners, new sex partner and unprotected sex) with the implant compared with DMPA documented in the ECHO study. ECHO TRIAL REGISTRATION: ClinicalTrials.gov , number NCT02550067 15/09/2015. Contraception, or family planning, is central to the role of women in societies. It is most important to have accurate information on the relative side-effects of various contraceptive options in order to empower women to make informed choices regarding their preferred method. Hormonal contraceptives contain various forms of the female sex hormones, estrogens and/or progestogens. These hormones have direct effects on the users, as well as modifying the levels of the users' own circulating sex hormones, both the 'female' and the 'male' sex hormones (androgens). In this study, consenting participants requesting contraception, were allocated randomly to receive either depot medroxyprogesterone acetate (DMPA-IM) a 3-monthly progestogen injection, the copper intrauterine device (IUD), a non-hormonal contraceptive inserted within the womb, or the levonorgestrel implant, a device placed under the skin which releases a progestogen for 5 years. We measured the participants' androgen levels after 6 months, and found for the first time that the active form of testosterone (free testosterone) was 29% higher with the implant than with DMPA-IM. The level with the IUD was intermediate, and significantly different from the other two methods. This finding is relevant to the effects experienced by users of these methods, because free testosterone has effects on sexual function, bone health and mood, as well as on conditions such as acne and hair distribution patterns.

RESUMEN

OBJECTIVES: To measure plasma concentrations of medroxyprogesterone acetate (MPA) in users with epilepsy treated with antiseizure medications and compare these to MPA concentrations in those without epilepsy. STUDY DESIGN: For this multisite cross-sectional study, we obtained a single blood sample from those with epilepsy treated with various antiseizure medications (n = 18) within the week before their next depot medroxyprogesterone injection. Among the participants without epilepsy (n = 20), 10 similarly were scheduled within the week prior to the next injection, and 10 were scheduled at earlier intervals to attempt to balance the time intervals between groups. MPA concentrations were determined by a validated assay. RESULTS: MPA concentrations were similar among those with epilepsy and controls and between groups with and without the use of enzyme-inducing medications. The lowest MPA concentrations, under 0.07 ng/mL, were observed among two of eight using enzyme-inducing antiseizure medications, one of 10 using noninducing medications, and one of 19 controls had concentrations below 0.2 ng/mL. CONCLUSIONS: In this exploratory study, lower MPA concentrations in some participants using enzyme-inducing antiseizure medications suggest a potential interaction that could reduce depot medroxyprogesterone efficacy.

RESUMEN

PURPOSE: Short-acting progestin-only injectables containing depot medroxyprogesterone acetate (DMPA) are a safe method of contraception. Although DMPA has been available for several decades, there is little data on its influence on the risk of breast cancer. Hence, the aim of this paper was to provide an overview of the existing studies and create clarity regarding a possible association with breast cancer. METHODS: Literature searches were executed in MEDLINE, Embase, the Cochrane Library, ClinicalTrials.gov and ICTRP. Search terms were related to DMPA and breast cancer. After elimination of duplicates, 3'850 studies were identified and assessed according to inclusion and exclusion criteria. Finally, ten studies were selected and included in this review. RESULTS: All the selected papers were case-control-studies, except for one pooled analysis and one study comparing observed and expected number of cancer cases. Most of the included studies found no overall elevated breast cancer incidence in DMPA users, only one study found a slightly increased risk and two studies concluded with a significant increase for the overall breast cancer risk. CONCLUSION: There is little evidence that DMPA may increase the overall risk for breast cancer. However, the incidence of breast cancer is possibly increased in current and more recent users, especially in women younger than 35 years. Long-term use did not result in any risk increase. Nevertheless, further studies will be necessary to confirm these findings and weigh up the individual risks and benefits of this contraceptive method.

RESUMEN

The injectable progestin depot-medroxyprogesterone acetate (DMPA) is a popular contraceptive choice in sub-Saharan Africa although mouse models indicate it weakens genital epithelial integrity and barrier function and increases susceptibility to genital infection. The intravaginal ring NuvaRing® is another contraceptive option that like DMPA suppresses hypothalamic pituitary ovarian (HPO) axis function with local release of progestin (etonogestrel) and estrogen (ethinyl estradiol). As we previously reported that treating mice with DMPA and estrogen averts the loss of genital epithelial integrity and barrier function induced by DMPA alone, in the current investigation we compared genital levels of the cell-cell adhesion molecule desmoglein-1 (DSG1) and genital epithelial permeability in rhesus macaques (RM) treated with DMPA or a NuvaRing®re-sized for RM (N-IVR). While these studies demonstrated comparable inhibition of the HPO axis with DMPA or N-IVR, DMPA induced significantly lower genital DSG1 levels and greater tissue permeability to intravaginally administered low molecular mass molecules. By identifying greater compromise of genital epithelial integrity and barrier function in RM administered DMPA vs. N-IVR, our results add to the growing body of evidence that indicate DMPA weakens a fundamental mechanism of anti-pathogen host defense in the female genital tract.

RESUMEN

Objectives: This study aimed to evaluate and compare local tolerability of investigational drug TV-46046 and reference drug Depo-subQ Provera 104, both containing medroxyprogesterone acetate (MPA) as an active ingredient. Study design: We conducted a randomized, crossover, single-center study. Twenty-seven healthy women aged 25 to 47 years at low risk of pregnancy received a subcutaneous injection of each of the four study drugs (120 mg/0.3 mL of TV-46046, 60 mg/0.3 mL of diluted TV-46046, 0.3 mL of TV-46046 placebo, and 104 mg/0.65 mL of Depo-subQ 104) in different quadrants of the abdomen. We assessed local tolerability by occurrence of injection site reactions (ISRs), as well as injection site pain and overall safety for at least 9 months postinjections. Results: Of a total of 108 study injections, three injections were partial due to needle blockage. We observed a total of 30 ISRs following 105 full-dose injections, including hypopigmentation (n = 24), bruising (n = 4), and atrophy/dimple (n = 2). Eleven cases of hypopigmentation occurred following 25 full-dose injections of undiluted TV-46046 (44.0%), six following 27 full-dose injections of diluted TV-46046 (22.2%), and seven following 26 full-dose injections of Depo-subQ 104 (26.9%). Hypopigmentations occurred on average 8 months postinjection. Injection pain was minimal and dissipated quickly after all four injections. Conclusions: Subcutaneous administration of MPA in a suspension formulation is associated with the delayed onset of hypopigmentation at the site of injection. Although not statistically significant, the rate of ISRs was over 60% higher for undiluted TV-46046 compared to Depo-subQ 104. This difference bears careful monitoring in future studies of TV-46046. Implications: From a safety standpoint, investigational drug TV-46046 is appropriate for further clinical testing as a 6-month contraceptive injectable. The previously underreported hypopigmentation associated with subcutaneous administration of MPA warrants further investigation and acceptability assessment among users of existing Depo-subQ 104 as well as careful monitoring of local tolerability of TV-46046 in future clinical trials. Trial registration: Registered at clinicaltrials.gov no: NCT02817464.

RESUMEN

BACKGROUND: Self-administered depot medroxyprogesterone acetate subcutaneous injectable contraception (DMPA-SC) is registered in many countries. It shows great potential for improving contraceptive access, continuation, and autonomy. However, there are challenges in rolling out this new efficacious intervention, and major implementation problems have been encountered during scale-up. OBJECTIVE: To describe the implementation strategies to scale up self-administered DMPA-SC and the barriers, facilitators, and outcomes of these programs. METHOD: Recent guidelines, including the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews, were used to design and report this review. An article or report was eligible for inclusion if it reported interventions that could scale up self-administered DMPA-SC implementation or its facilitators, barriers, or outcomes. We searched six electronic databases and the grey literature for eligible articles and reports. Two reviewers independently screened the document titles, abstracts, and full texts to identify eligible documents. Data were extracted using structured forms. Using the Effective Practice and Organization of Care (EPOC) taxonomy of health systems framework for thematic analysis, data were presented in a narrative approach. RESULTS: Of the 755 retrieved documents, 34 were included in this review. Most of the documents included were multi-country reports (n = 14), and all documents were published within the last 5 years (2018-2021). This review identified documents that reported interventions in all EPOC domains. The most-reported interventions were: task-sharing amongst health workforce cadres, engaged leadership, encouraging policies, training and education, DMPA-SC demand generation, integration into existing programs, improved funding mechanisms, collaboration with development partners, and supply chain strengthening. The main barriers were suboptimal funding, inadequate human resources, and poor logistics supply of DMPA-SC. There was minimal evidence of scale-up outcomes. CONCLUSION: This scoping review reported a wide range of interventions employed by countries and programs to scale up DMPA-SC self-administration but minimal evidence of the scale-up outcomes. Evidence from this review can help design better programs that improves access to quality family planning services to achieve the Sustainable Development Goals (SDG) targets 3.7. However, efforts should focus on rigorous implementation research that assess scaled up self-administered DMPA-SC interventions and report their outcomes. REGISTRATION: The protocol for this review was registered in the protocols.io repository ( https://www.protocols.io/view/a-protocol-for-a-scoping-review-of-implementation-x54v9yemmg3e/v1 ).

RESUMEN

PURPOSE OF REVIEW: The long-acting reversible intramuscularly-injected contraceptive depot medroxyprogesterone acetate (DMPA-IM) is widely used by cisgender women in Africa. Although DMPA-IM provides reliable contraception, potential effects on the female genital tract (FGT) mucosa have raised concern, including risk of HIV infection. This review summarises and compares evidence from observational cohort studies and the randomised Evidence for Contraceptive Options in HIV Outcomes (ECHO) Trial. RECENT FINDINGS: Although previous observational studies found women using DMPA-IM had higher abundance of bacterial vaginosis (BV)-associated bacteria, increased inflammation, increased cervicovaginal HIV target cell density, and epithelial barrier damage, sub-studies of the ECHO Trial found no adverse changes in vaginal microbiome, inflammation, proteome, transcriptome, and risk of viral and bacterial STIs, other than an increase in Th17-like cells. Randomised data suggest that DMPA-IM use does not adversely change mucosal endpoints associated with acquisition of infections. These findings support the safe use of DMPA-IM in women at high risk of acquiring STIs, including HIV.

RESUMEN

OBJECTIVE: To assess the associations between depot medroxyprogesterone acetate (DMPA) and endometrial cancer. METHODS: This multicenter case-control study was conducted among tertiary hospitals in Thailand. Patients were women with endometrial cancer. Controls were women admitted for other conditions, matched for age within 5 years of the patients' age. The controls had to have no abnormal vaginal bleeding, history of hysterectomy, or cancers of the other organs. A standardized questionnaire was used to gather information. Conditional logistic regression was applied to calculate adjusted odds ratio (aORs) and 95% confidence intervals (CIs). RESULTS: During 2015 to 2021, 378 patients and 1134 controls were included. Ever use of DMPA was associated with a 70% decreased overall risk of endometrial cancer (aOR, 0.30 [95% CI, 0.21-0.42]). Endometrial cancer risk declined by 3% (aOR, 0.97 [95% CI, 0.96-0.98]) for every 3 months of DMPA use. The magnitude of the decline in endometrial cancer risk did not vary appreciably by cancer subtypes (aOR, 0.26 [95% CI, 0.17-0.41] and 0.38 [95% CI, 0.22-0.65] for low-grade and high-grade tumors, respectively). CONCLUSIONS: Depot medroxyprogesterone acetate use was inversely associated with endometrial cancer risk in a duration-dependent manner. This association was independent of cancer subtype.

RESUMEN

OBJECTIVES: Self-administered subcutaneous (SC) depot medroxyprogesterone acetate (DMPA) can improve contraception access by eliminating a health center visit for administration. For patients at our New York City health centers who were offered a switch to self-administered DMPA-SC at the onset of the coronavirus 2019 (COVID-19) pandemic, we sought to understand their experience of choosing to switch, of accessing and using the method, and their method satisfaction. STUDY DESIGN: Individual interview study of 22 patients using intramuscular DMPA prior to the start of the pandemic. All had a telehealth visit to discuss switching to self-administered DMPA-SC and received a DMPA-SC prescription during the first months of COVID-19. We used a grounded theory analysis approach. RESULTS: Respondents viewed switching to self-administered DMPA-SC as a decision they had to make if they wanted to continue DMPA. Most respondents experienced logistical challenges acquiring DMPA-SC from their pharmacy. Issues around convenience were important to respondents; however what respondents found convenient varied. Despite all this, respondents appreciated having the option of DMPA-SC and felt it to be overall empowering. CONCLUSIONS: This study exploring patients' experience with self-administered DMPA-SC during the initial year of the COVID-19 pandemic found that, notwithstanding initial hesitation about self-administered injections and logistical challenges getting the SC formulation, many found the experience of trying self-administered DMPA-SC to be empowering and appreciated having this option. Thus, self-administered DMPA-SC should be included in clinicians' routine contraception counseling and provision, insurance companies should cover DMPA-SC without requiring prior authorization, and pharmacies should consistently stock DMPA-SC. IMPLICATIONS: Self-administered DMPA-SC is an acceptable contraception option that provides an opportunity to maintain contraception access while eliminating need for an in-person visit. Thus, self-administered DMPA-SC should be included in clinicians' routine contraception counseling and provision, insurance companies need to cover this contraceptive without need for prior authorization, and pharmacies should consistently stock DMPA-SC.

RESUMEN

Important questions remain on how hormonal contraceptives alter the local immune environment and the microbiota in the female genital tract and how such effects may impact susceptibility to HIV infection. We leveraged samples from a previously conducted clinical trial of Malawian women with (n = 73) and without (n = 24) HIV infection randomized to depot medroxyprogesterone acetate (DMPA) or the levonogestrel implant in equal numbers within each group and determined the effects of these hormonal contraceptives (HCs) on the vaginal immune milieu and the composition of the vaginal microbiota. Longitudinal data for soluble immune mediators, measured by multiplex bead arrays and enzyme-linked immunosorbent assays (ELISAs), and vaginal microbiota, assessed by 16S rRNA gene amplicon, were collected prior to and over a period of 180 days post-HC initiation. DMPA and levonogestrel had only minimal effects on the vaginal immune milieu and microbiota. In women with HIV, with the caveat of a small sample size, there was an association between the median log10 change in the interleukin-12 (IL-12)/IL-10 ratio in vaginal fluid at day 180 post-HC compared to baseline when these women were classified as having a community state type (CST) IV vaginal microbiota and were randomized to DMPA. Long-lasting alterations in soluble immune markers or shifts in microbiota composition were not observed. Furthermore, women with HIV did not exhibit increased viral shedding in the genital tract after HC initiation. Consistent with the results of the ECHO (Evidence for Contraceptive Options and HIV Outcomes) trial, our data imply that the progestin-based HC DMPA and levonorgestrel are associated with minimal risk for women with HIV. (This study has been registered at ClinicalTrials.gov under registration no. NCT02103660). IMPORTANCE The results of the Evidence for Contraceptive Options and HIV Outcomes (ECHO) trial, the first large randomized controlled clinical trial comparing the HIV acquisition risk of women receiving DMPA, the levonorgestrel (LNG) implant, or the copper intrauterine device (IUD), did not reveal an increased risk of HIV acquisition for women on any of these three contraceptives. Our study results confirm that the two different progestin-based hormonal contraceptives DMPA and levonogestrel will not increase the risk for HIV infection. Furthermore, DMPA and levonogestrel have only minimal effects on the immune milieu and the microbiota in the vaginal tract, attesting to the safety of these hormonal contraceptives.

RESUMEN

BACKGROUND: There continues to be controversy regarding the simultaneous encouragement of both breastfeeding and immediate postpartum contraception. RESEARCH AIM: To explore postpartum women's perspectives about breastfeeding and their breastfeeding behaviors, while using one of three different hormonally systemic contraceptive methods immediately postpartum over a 6 month period of time. METHODS: This was a retrospective, longitudinal, three group comparative, secondary analysis of a prospective cohort study (N = 471) of immediate postpartum contraception. Breastfeeding, for this study, was defined as providing any human milk to the infant. Participants who chose one of three different hormonally systemic forms of contraception immediately postpartum (a long-acting hormonal reversible contraceptive (n = 200), depot medroxyprogesterone acetate 150 mg (n = 98), or a non-hormonal method (n = 173)) were compared at hospital discharge, 6 weeks, 3 months, and 6 months postpartum. The primary outcome was any breastfeeding at 6 months. Secondary outcomes included any and exclusive breastfeeding, concerns about breastfeeding while using contraception, and reasons for breastfeeding discontinuation. RESULTS: There was no significant difference in the rate of any breastfeeding between the two hormonal and the non-hormonal contraceptive groups at 6 months postpartum (long-acting hormonal 20.1%, non-hormonal 21.7%, depot medroxyprogesterone acetate 13.9%, p = .77, 0.28, respectively). The number of participants who reported stopping breastfeeding due to decreased milk supply was not significantly different between any groups at all time points (total number who discontinued at 6 months postpartum was long-acting hormonal 24.7%, non-hormonal 25.1%, depot medroxyprogesterone acetate 19.3%, p = .30). CONCLUSIONS: Breastfeeding perspectives and behavioral outcomes over the first 6 months postpartum were not influenced by participants chosen form of immediate postpartum contraception.

RESUMEN

Depot-medroxyprogesterone acetate (DMPA) is a highly effective long acting reversible contraceptive. Alterations in lipid profile have been associated with use of DMPA, however there is considerable debate about how profound these effects are. Hence the aim of this study is to determine the effect of DMPA on lipid profile and the associated cardiovascular risks. This was a prospective longitudinal study conducted at the family planning clinic of Olabisi Onabanjo University Teaching Hospital Sagamu, Ogun State. Sixty eight new acceptors of DMPA who had their blood samples collected for lipid profile assays at initiation of DMPA, and then at 3 months and 6 months. Data were analyzed using SPSS version 24. After 3 months of DMPA use, there was statistically significant increase in serum Total Cholesterol (TC) concentration (P=0.022), serum Low Density Lipoprotein (LDL) concentration (P=0.033), non significant increase in serum Triglyceride (TG) concentration (P=0.150) and non-significant decrease in serum Higher Density Lipoprotein (HDL) concentration (P=0.076). However, after 6 months of DMPA use, there was statistically significant increase in serum TC concentration (P=0.002), serum LDL concentration (P=0.003), serum TG concentration (P=0.001) and significant decrease in serum HDL concentration (P=0.001). DMPA use is associated with increased serum TC, TG, LDL, and reduction in HDL after 6 months of use. These changes in lipid profile may increase the risk of cardiovascular diseases.

RESUMEN

BACKGROUND: Injectable contraceptives are the most popular method of contraception in sub-Saharan Africa (SSA), but their availability in clinical settings has been severely limited, despite the scarcity of health care providers and limited access to health facilities. WHO and USAID have endorsed the community-based distribution of injectable contraceptives as a promising option for improving access to family planning services and expanding the method mix for women who want to limit the number of births. Studies have shown that community health workers (CHWs) can provide women with injectable contraceptives that meet acceptable quality standards. The goal of this study is to identify, evaluate and synthesize evidence supporting the use of community-based administration of injectable contraceptives in SSA. METHODS: This review's guidance was based on a previously developed protocol. Nine international electronic databases and the websites of organizations known to support community-based reproductive health initiatives in SSA were searched systemically. Experts in this area were also contacted for the identification of unpublished literature and ongoing studies. The reference lists of eligible studies were reviewed. The Effective Public Practice Project tool was used to assess the quality and risk of bias in eligible studies. Data were extracted and analysed using a custom data extraction form and a narrative synthesis. RESULTS: The search strategy identified a total of 1358 studies with 12 studies meeting the inclusion criteria. One unpublished study was provided by an expert making a total of 13 studies. The results showed that irrespective of the study designs, well-trained CHWs can competently administer injectable contraceptives safely and community-based delivery of injectable contraceptives is acceptable in SSA. Also, the use of community health workers in the provision of depot-medroxyprogesterone acetate expanded access to inhabitants of hard-to-reach areas and led to an overall uptake of injectable contraceptives as well as family planning. Studies that compared CHWs to clinic-based providers revealed equivalent or higher levels of performance in favour of CHWs. CONCLUSIONS: The CHWs can competently provide injectable contraceptives within SSA communities if appropriately trained and supervised. Hence, SSA policymakers should give this initiative due consideration as a way of improving access to family planning services.

RESUMEN

Contraceptive self-injection (SI) is a new self-care practice with potential to transform women's family planning access by putting a popular method, injectable contraception, directly into the hands of users. Research shows that SI is feasible and acceptable; evidence regarding how to design and implement SI programs under real-world conditions is still needed. This evaluation examined women's experiences when self-injection of subcutaneous depot medroxyprogesterone acetate (DMPA-SC) was introduced in Uganda alongside other contraceptive options in the context of informed choice. We conducted structured survey interviews with 958 randomly selected SI clients trained in three districts in 2019. SI clients demonstrated their injection technique on a model to permit an assessment of injection proficiency. A randomly selected subset of 200 were re-interviewed 10-17 months post-training to understand resupply experiences, waste disposal practices and continuation. Finally, we conducted survey interviews with a random sample of 200 clients who participated in training but declined to self-inject. Data were analyzed using Stata IC/14.2. Differences between groups were measured using chi square and t-tests. Multivariate analyses predicting injection proficiency and SI adoption employed mixed effects logistic regression. Nearly three quarters of SI clients (73%) were able to demonstrate injection proficiency without additional instruction from a provider. Years of education, having received a complete training, practicing, and taking home a job aid were associated with higher odds of proficiency. Self-reported satisfaction and continuation were high, with 93% reinjecting independently 3 months post-training. However, a substantial share of those trained opted not to self-inject. Being single, having a partner supportive of family planning use, training with a job aid, practicing, witnessing a demonstration and exposure to a full training were associated with higher odds of becoming an SI client; conversely, those trained in a group had reduced odds of becoming an SI client. The self-care program was successful for the majority of women who became self-injectors, enabling most women to demonstrate SI proficiency. Nearly all those who opted to self-inject reinjected independently, and the majority continued self-injecting for at least 1 year. Additional research should identify strategies to facilitate adoption by women who wish to self-inject but face challenges.

RESUMEN

Background: Evidence on a possible association between newer hormonal contraceptives (HC) and risk of breast cancer remains inconclusive, especially as concerns progestogen-only methods. Methods: In this nationwide prospective cohort study, all Swedish women aged 15-34 at study start on January 1st 2005, or who turned 15 years during the study period, were followed until December 31st 2017. Using information from seven National Registers, we assessed the risk ratio of developing breast cancer and breast cancer in situ in relation to different HC using Poisson regression. We adjusted the analyses for several known confounders of breast cancer. Findings: This cohort included 1.5 million women providing more than 14 million person-years. During the study period, 3842 women were diagnosed with breast cancer. Compared with never users of any HC, we found no increased risk of developing breast cancer among current users of any combined HC, IRR 1.03 (0.91-1.16), whereas current users of progestogen-only methods had an increased risk of developing breast cancer, IRR 1.32 (1.20-1.45). Across all types of HC, the risk of developing breast cancer appeared to be highest the first five years of use (combined HC IRR 1.39 (1.14-1.69); progestogen-only methods IRR 1.74 (1.44-2.10). The risk disappeared ten years after the women stopped using HC. The absolute risk of breast cancer per 100,000 women-years was 22.4 for never users, 10.9 for current users of combined HC, and 29.8 for current users of progestogen-only methods. Interpretation: Current use of progestogen-only methods is associated with a small increased risk of developing breast cancer, whereas we could only detect an increased risk among users of combined HC during the first five years of use. This may partly be explained by a selective prescription of progestogen-only methods to women with risk factors for breast cancer, like smoking or obesity. As the absolute risk of breast cancer was small, the many health benefits associated with HC must also be taken into account in contraceptive counselling. Funding: This study was funded by the Swedish Cancer Society and by the Uppsala County Council, the Faculty of Medicine at Uppsala University.
