Contributions of side effects to contraceptive discontinuation and method switch among Kenyan women: a prospective cohort study.

ABSTRACT:

Objective

To determine the contribution of specific contraceptive side effects to method switch and modern-method discontinuation among Kenyan women.

Design

A prospective cohort study.

Setting

Five counties in Western Kenya.

Participants

Women aged ≥18 years old and emancipated female minors ≥14 years old using modern, reversible contraception were recruited while attending 10 public health facilities.

Methods

Patient-reported adverse effect symptoms, method switch and discontinuation were reported through weekly text message-based surveys for 24 weeks.

Main outcome measurements

Prevalence, hazards ratio (HR).

Results

Among 825 women, 44% were using implants, 43% injectables, 7% an intrauterine device and 6% oral contraceptive pills at enrolment. Most (61%) women were continuing a method used in the previous month. During the 24-week follow up, incidence of contraceptive switch was 61.3 per 100 person-years (95% confidence interval [CI] 52.4-71.8) and incidence of discontinuation was 38.5 per 100 person-years (95% CI 31.6-47.0). On average, one-quarter (prevalence [Pr] 0.24, 95% CI 0.22-0.26) of participants reported side effects or method problems weekly, with sexual side effects the most prevalent symptom (Pr 0.15, 95% CI 0.13-0.16). Lack of expected bleeding was associated with higher risk of method switch (adjusted hazard ratio [aHR] 2.36, 95% CI 1.22-4.57). Risk of all-modern method discontinuation was higher among women experiencing irregular bleeding (aHR 2.39, 95% CI 1.20-4.77), weight changes (aHR 2.72, 95% CI 1.47-4.68) and sexual side effects (aHR 2.42, 95% CI 1.40-4.20).

Conclusions

Addressing irregular bleeding, weight changes and sexual side effects through development of new products that minimise these specific side effects and anticipatory counseling may reduce method-related discontinuation.

Project description:ObjectiveWe developed and validated a pragmatic risk assessment tool for identifying contraceptive discontinuation among Kenyan women who do not desire pregnancy.Study designWithin a prospective cohort of contraceptive users, participants were randomly allocated to derivation (n = 558) and validation (n = 186) cohorts. Risk scores were developed by selecting the Cox proportional hazards model with the minimum Akaike information criterion. Predictive performance was evaluated using time-dependent receiver operating characteristic curves and area under the curve (AUC).ResultsThe overall contraceptive discontinuation rate was 36.9 per 100 woman-years (95% confidence interval [CI] 30.3-44.9). The predictors of discontinuation selected for the risk score included use of a short-term method or copper intrauterine device (vs. injectable or implant), method continuation or switch (vs. initiation), < 9 years of completed education, not having a child aged < 6 months, and having no spouse or a spouse supportive of family planning (vs. having a spouse who has unsupportive or uncertain attitudes towards family planning). AUC at 24 weeks was 0.76 (95% CI 0.64-0.87) with 70.0% sensitivity and 78.6% specificity at the optimal cut point in the derivation cohort. Discontinuation was 3.8-fold higher among high- vs. low-risk women (95% CI 2.33-6.30). AUC was 0.68 (95% CI 0.47-0.90) in the validation cohort. A simplified score comprising routinely collected variables demonstrated similar performance (derivation-AUC: 0.73 [95% CI 0.60-0.85]; validation-AUC: 0.73 [95% CI 0.51-0.94]). Positive predictive value in the derivation cohort was 31.4% for the full and 28.1% for the simplified score.ConclusionsThe risk scores demonstrated moderate predictive ability but identified large proportions of women as high risk. Future research is needed to improve sensitivity and specificity of a clinical tool to identify women at high risk for experiencing method-related challenges.ImplicationsContraceptive discontinuation is a major driver of unmet contraceptive need globally. Few tools exist for identifying women who may benefit most from additional support in order to meet their contraceptive needs and preferences. This study developed and assessed the validity of a provider-focused risk prediction tool for contraceptive discontinuation among Kenyan women using modern contraception. High rates of early discontinuation observed in this study emphasize the necessity of investing in efforts to develop new contraceptive technologies and stronger delivery systems to better align with women's needs and preferences for voluntary family planning.

Project description:BackgroundIntravaginal washing, practised by a significant proportion of women globally, is associated with acquisition of human immunodeficiency virus (HIV), sexually transmitted infections and bacterial vaginosis (BV). A single prior study among women in the United States found that vaginal washing was associated with lower fecundability.ObjectiveTo examine the association between vaginal washing and fecundability among Kenyan women.MethodsHIV-negative Kenyan women who were trying to conceive and reported no history of infertility care-seeking were followed prospectively for incident pregnancy for up to six months. At monthly visits, participants reported the first day of last menstrual period, sexual behaviour, vaginal washing behaviour, underwent pregnancy testing and provided vaginal swabs for detection of BV by Gram stain (Nugent score ≥7). Discrete time proportional probability models were used to estimate fecundability ratio (FR) and 95% confidence interval (CI) comparing menstrual cycles when women reported vaginal washing to menstrual cycles when no vaginal washing was reported.ResultsFour hundred and fifty-eight women contributed 1,376 menstrual cycles and 255 pregnancies. At enrolment, a third (35.2%, 161 of 458) of participants reported vaginal washing with the majority using water only (73.9%, 119 of 161). After adjustment for age, frequency of unprotected intercourse and study site, vaginal washing in the prior four weeks was associated with a 29% lower fecundability (adjusted FR [aFR] 0.71, 95% CI 0.53, 0.94), which did not change after further adjustment for BV at the visit prior to each pregnancy test (aFR 0.71, 95% CI 0.54, 0.95).ConclusionsPericonceptual vaginal washing may reduce fecundability. Potential mechanisms include vaginal washing-associated changes in the vaginal microbiota, inflammation, disruption of cervical mucus and effects on sperm function. Vaginal washing has no known health benefits, and cessation may improve women's likelihood of conceiving.

Project description:BackgroundThe quality of contraceptive counseling that women receive from their provider can influence their future contraceptive continuation. We examined (1) whether the quality of contraceptive service provision could be measured in a consistent way by using existing tools from 2 large-scale social franchises, and (2) whether facility quality measures based on these tools were consistently associated with contraceptive discontinuation.MethodsWe linked existing, routinely collected facility audit data from social franchise clinics in Pakistan and Uganda with client data. Clients were women aged 15-49 who initiated a modern, reversible contraceptive method from a sampled clinic. Consented participants completed an exit interview and were contacted 3, 6, and 12 months later. We collapsed indicators into quality domains using theory-based categorization, created summative quality domain scores, and used Cox proportional hazards models to estimate the relationship between these quality domains and discontinuation while in need of contraception.ResultsThe 12-month all-modern method discontinuation rate was 12.5% among the 813 enrolled women in Pakistan and 5.1% among the 1,185 women in Uganda. We did not observe similar associations between facility-level quality measures and discontinuation across these 2 settings. In Pakistan, an increase in the structural privacy domain was associated with a 60% lower risk of discontinuation, adjusting for age and baseline method (P<.001). In Uganda, an increase in the management support domain was associated with a 33% reduction in discontinuation risk, controlling for age and baseline method (P=.005).ConclusionsWe were not able to leverage existing, widely used quality measurement tools to create quality domains that were consistently associated with discontinuation in 2 study settings. Given the importance of contraceptive service quality and recent advances in indicator standardization in other areas, we recommend further effort to harmonize and simplify measurement tools to measure and improve contraceptive quality of care for all.

Project description:ObjectiveLong-acting reversible contraceptive (LARC) method uptake has been low within the context of HIV prevention trials. Within a multinational study (MTN-020/ASPIRE), the Contraceptive Action Team improved LARC accessibility and uptake. In this secondary analysis, we determined the rate of contraceptive method continuation among the women enrolled.Study designASPIRE was a randomized, double-blinded, placebo-controlled phase III safety and effectiveness study of the Dapivirine Vaginal Ring for HIV-1 prevention. Between 2012 and 2014, sexually active women aged 18-45 from Malawi, South Africa, Uganda and Zimbabwe were enrolled. All participants were required to use contraception for enrollment to the study and could choose between all highly effective contraceptive methods available in their respective countries. Women were seen monthly and could change methods at any time. Continuation rates from study enrollment to 6 and 12 months were determined.ResultsThe overall contraceptive method continuation rate was 77% (1972/2551) at 6 months and 66% (1694/2551) at 12 months. The 6- and 12-month continuation rates were highest for implantable contraceptives (89%, 82%) followed by copper intrauterine device (83%, 77%). Rates of continuation for injectable contraceptives depot medroxyprogesterone acetate (80%, 69%) and norethisterone enanthate (71%, 54%) were higher than for oral contraceptives, which were continued at 47% at 6 months and 35% at 12 months. The continuation rates of all methods did not differ by users with and without previous contraceptive experience.ConclusionsLARC methods have the highest rates of continuation at 12 months and should be routinely offered in the context of HIV prevention trials in sub-Saharan Africa.ImplicationsIntrauterine devices and contraceptive implant continuation was high at 12 months among women participating in an HIV prevention trial in sub-Saharan Africa and LARCs and should be routinely offered.

Project description:BackgroundThere are gaps in understanding longitudinal patterns and predictors of perinatal depressive symptoms in sub-Saharan Africa. This study aimed to explore trajectories of depressive symptoms and associated factors from pregnancy to 9 months post partum among Kenyan women.MethodsIn this prospective cohort study, we analysed data from the PrEP Implementation for Mothers in Antenatal Care (PrIMA) study in which HIV-negative women were enrolled in pregnancy and followed up to 9 months post partum in 20 public sector maternal-child health clinics in western Kenya. Pregnant women were eligible for enrolment if they were not infected with HIV, aged 15 years or older, and were able to provide consent. Eligible participants were screened and enrolled between Jan 15, 2018, and July 31, 2019, and followed up to 9 months post partum, with the last participant study visit conducted on Jan 15, 2021. Study nurses serially assessed depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CESD-10), intimate partner violence with the Hurt, Insult, Threaten, Scream scale, and social support with the Medical Outcomes Study scale. Generalised estimating equations were used to identify correlates of moderate-to-severe depressive symptoms (CESD-10 score ≥10) and group-based trajectory modelling identified discrete trajectories of perinatal depressive symptoms.FindingsAmong 4447 participants in the main PrIMA study, 3555 had complete depressive symptom data in pregnancy and depressive symptom data post partum and were included in the primary analysis. Median age was 24·0 years (IQR 21·0-28·7), 1330 (38%) participants had low social support, and 278 (8%) reported intimate partner violence in pregnancy. All participants (100%) were female and all (100%) were of African Kenyan ethnicity. Prevalence of moderate-to-severe depressive symptoms was higher in pregnancy than post partum (870 [24·5%; 95% CI 23·1-25·9] vs 597 [6·8%; 15·6-18·1]; p<0·0001). Five patterns of depressive symptoms were identified; persistent moderate-to-severe depressive symptoms in pregnancy and post partum (295 [8·3%]), moderate-to-severe depressive symptoms in pregnancy that resolved post partum (139 [3·9%]), moderate-to-severe depressive symptoms that emerged post partum (40 [1·1%]), chronically mild symptoms (2709 [76·2%]), and no depressive symptoms (372 [10·5%]). Emergent moderate-to-severe depressive symptoms were associated with older age. Emergent, persistent, and resolving moderate-to-severe depressive symptoms were associated with intimate partner violence during pregnancy; and persistent and resolving moderate-to-severe depressive symptoms were associated with low social support and high HIV risk (all p<0·05). Moderate-to-severe depressive symptom risk was significantly increased with intimate partner violence (adjusted odds ratio 2·07 [95% CI 1·81-2·31]; p<0·0001), low social support (1·74 [1·56-1·95]; p<0·0001), and partner HIV-positive status (1·48 [1·22-1·78]; p<0·0001). 23·34% (95% CI 18·77-27·65) of cases of perinatal moderate-to-severe depressive symptoms were attributable to low social support.InterpretationOne third of women had perinatal moderate-to-severe depressive symptoms; nearly half of these had higher severity phenotypes of resolving, persistent, and emerging moderate-to-severe depressive symptoms that might require tailored interventions. Perinatal women with comorbid psychosocial stressors such as intimate partner violence and previous pregnancy loss should be prioritised for mental health services that augment social support within routine maternal-child health care.FundingNational Institutes of Health.TranslationFor the Kiswahili translation of the abstract see Supplementary Materials section.

Project description:BackgroundThe effective use of contraception among adolescents and young women can reduce the risk of unintended pregnancies. However, the prevalence of contraceptive use remains low in this age group. The objective of this study was to estimate the rate of contraceptive method discontinuation among adolescents and young women and to identify its associated factors in Burkina Faso, Mali, and Niger.MethodThis was a secondary analysis of data from Demographic and Health Surveys of Burkina Faso (2010), Mali (2012-2013), and Niger (2012). The dependent variable was the time to discontinuation of contraceptive methods. Independent variables were represented by sociodemographic, socioeconomic, and cultural characteristics. Mixed-effects survival analysis with proportional hazards was used to identify the predictors.ResultsA total of 2,264 adolescents and young women aged 15 to 24 years were included in this analysis, comprising 1,100 in Burkina Faso, 491 in Mali, and 673 in Niger. Over the last five years, the overall contraceptive discontinuation rate was 68.7% (50.1% in Burkina Faso, 59.6% in Mali, and 96.8% in Niger). At the individual level, in Burkina Faso, occupation (aHR = 0.33), number of living children (aHR = 2.17), marital status (aHR = 2.93), and region (aHR = 0.54) were associated with contraceptive discontinuation. Except for education and marital status, we found the same factors in Mali. In Niger, a women's education level (aHR = 1.47) and her partner (aHR = 0.52) were associated with discontinuation. At the community level, the region of origin was associated with discontinuation of contraceptive methods.ConclusionMost adolescents and young women experienced at least one episode of discontinuation. Discontinuation of contraceptive methods is associated with the level of education, occupation, number of children, marital status, and desire for children with the spouse. Promotion of contraceptive interventions should target adolescents, young women, and their partners, as well as those with a low education level or in a union.

Project description:BackgroundUnderstanding contraceptive use dynamics is critical to addressing unmet need for contraception. Despite evidence that male partners may influence contraceptive decision-making, few studies have prospectively examined the supportive ways that men influence women's contraceptive use and continuation.ObjectiveThis study sought to understand the predictive effect of partner influence, defined as partner's fertility intentions and support for contraception, and discussions about avoiding pregnancy prior to contraceptive use, on contraceptive use dynamics (continuation, discontinuation, switching, adoption) over a one-year period.MethodsThis study uses nationally representative longitudinal data of Ugandan women aged 15-49 collected in 2018-2019 (n = 4,288 women baseline; n = 2,755 women one-year follow-up). Two analytic sub-samples of women in union and in need of contraception at baseline were used (n = 618 contraceptive users at baseline for discontinuation/switching analysis; n = 687 contraceptive non-users at baseline for adoption analysis). Primary dependent variables encompassed contraceptive use dynamics (continuation, discontinuation, switching, and adoption); three independent variables assessed partner influence. For each sub-sample, bivariate associations explored differences in sociodemographic and partner influences by contraceptive dynamics. Multinomial regression models were used to examine discontinuation and switching for contraceptive users at baseline; logistic regression identified predictors of contraceptive adoption among non-users at baseline.ResultsAmong users at baseline, 26.3% of women switched methods and 31.5% discontinued contraceptive use by follow-up. Multinomial logistic regression, adjusting for women's characteristics, indicated the relative risk of contraceptive discontinuation doubled when women did not discuss pregnancy avoidance with their partner prior to contraceptive use. Partner influence was not related to method switching. Among non-users at baseline, partner support for future contraceptive use was associated with nearly three-fold increased odds of contraceptive adoption.SignificanceThese results highlight the potentially supportive role of male partners in contraceptive adoption. Future research is encouraged to elucidate the complex pathways between couple-based decision-making and contraceptive dynamics through further prospective studies.

Project description:Study questionIs bacterial vaginosis (BV) associated with fecundability?Summary answerWomen with BV may be at increased risk for sub-fecundity.What is known alreadyWhile BV has been associated with poor IVF outcomes, the association between vaginal microbiota disruption and non-medically assisted conception has not been thoroughly explored.Study design, size, durationKenyan women with fertility intent were enrolled in prospective cohort that included monthly preconception visits with vaginal fluid specimen collection and pregnancy testing. Four hundred fifty-eight women attempting pregnancy for ≤3 menstrual cycles at enrollment were eligible for this fecundability analysis.Participants/materials, setting, methodsAt monthly preconception visits, participants reported the first day of last menstrual period and sexual behavior, underwent pregnancy testing and provided vaginal specimens. Discrete time proportional probabilities models were used to estimate fecundability ratios (FRs) and 95% CI in menstrual cycles with and without BV (Nugent score ≥ 7) at the visit prior to each pregnancy test. We also assessed the association between persistent BV (BV at two consecutive visits) and fecundability.Main results and the role of chanceParticipants contributed 1376 menstrual cycles; 18.5% (n = 255) resulted in pregnancy. After adjusting for age, frequency of condomless sex and study site, BV at the visit prior to pregnancy testing was associated with a 17% lower fecundability (adjusted FR (aFR) 0.83, 95% CI 0.6-1.1). Persistent BV was associated with a 43% reduction in fecundability compared to cycles characterized by optimal vaginal health (aFR 0.57, 95% CI 0.4-0.8).Limitations, reasons for cautionDetection of vaginal microbiota disruption using Gram stain and a point-of-care test for elevated sialidase identified a non-optimal vaginal environment, but these non-specific methods may miss important relationships that could be identified by characterizing individual vaginal bacteria and bacterial communities using molecular methods. In addition, results may be subject to residual confounding by condomless sex as this was reported for the prior month rather than for the fertile window during each cycle.Wider implications of the findingsGiven the high global prevalence of BV and infertility, an association between BV and reduced fecundability could have important implications for a large number of women who wish to conceive. Multi-omics approaches to studying the vaginal microbiota may provide key insights into this association and identify potential targets for intervention.Study funding/competing interest(s)This work was supported by a National Institutes of Health grant (NICHD R01 HD087346-R.S.M.).
