An Assessment of Third-Party Reporting of Close Ties to Measure Sensitive Behaviors: The Confidante Method to Measure Abortion Incidence in Ethiopia and Uganda

Direct and indirect estimation of adolescent sexual intercourse and contraceptive use in Rajasthan India: an application of the best friend methodology

BACKGROUND

Existing estimates of adolescent sexual and reproductive health (ASRH) behaviors may be a gross undercount given the sensitivity of this behavior in Indian culture. The objective of this study was to estimate ASRH behaviors in Rajasthan, India using direct questions and the best friend approach that seeks to reduce social desirability bias.

METHODS

We used population-based data of adolescents aged 15-19 in Rajasthan collected between September and December 2022. Data include whether the respondent and her closest female friend ever had a partner, ever had sex, ever used contraception, and were currently using contraception. We estimated respondent and best friend ASRH outcomes separately, overall and among unmarried adolescents for whom we anticipate social desirability bias is greatest.

RESULTS

The best friend approach performed well, with method assumptions largely met even before adjustments. Respondent and best friend estimates were similar among all adolescents except for current contraceptive use, which was higher for friends (though not significantly so). However, we observed large differences in ASRH behaviors between unmarried respondents and friends, with a significantly higher percentage of friends who ever had a partner (4.3% respondents, 11.6% friends), and a slightly higher percentage who ever had sex (2.4%, 3.8%) and who were currently using contraception (17.0%, 19.7% among those in need of contraception).

CONCLUSIONS

We observed potential benefits of using the best friend methodology in estimating premarital sexual activity, but further work is needed to refine social network-based measures of sensitive adolescent behaviors in larger study samples to better understand ASRH needs.

Estimating induced abortion incidence and the use of non-recommended abortion methods and sources in two provinces of the Democratic Republic of the Congo (Kinshasa and Kongo Central) in 2021: results from population-based, cross-sectional surveys of reproductive-aged women

The changing abortion legal and practice landscape in the DRC in recent years calls for a re-examining of induced abortion experiences. The current study provides population-level estimates of induced abortion incidence and safety by women's characteristics in two provinces using direct and indirect approaches to assess indirect method performance. We use representative survey data on women aged 15-49 in Kinshasa and Kongo Central collected from December 2021 to April 2022. The survey had questions on respondents' and their closest friends' experience with induced abortion, including methods and sources used. We estimated one-year abortion incidence and proportion using non-recommended methods and sources overall and by background characteristics for each province separately for respondents and friends. The fully adjusted one-year friend abortion rate was 105.3 per 1000 women of reproductive age in Kinshasa and 44.3 per 1000 in Kongo Central in 2021; these were substantially higher than corresponding respondent estimates. Women earlier in their reproductive lifespan were more likely to have had a recent abortion. Approximately 17.0% of abortions in Kinshasa and one-third of abortions in Kongo Central involved non-recommended methods and sources according to respondent and friend estimates. The more accurate friend abortion incidence estimates indicate that women in the DRC often rely on abortion to regulate their fertility. Many use non-recommended means and sources to terminate, thus, significant work remains to actualise the commitments made in the Maputo Protocol to provide comprehensive reproductive health services that combine primary and secondary prevention services to reduce unsafe abortion and its consequences.

Abortion incidence and safety in Niger in 2021: Findings from a nationally representative cross-sectional survey of reproductive-aged women using direct and indirect measurement approaches

Niger is a country in which legal restrictions and a dearth of research has long limited our understanding of the extent and safety of induced abortion. The current study is the first national study of induced abortion in Niger. It uses direct (self-report) and indirect (best friend method) to provide nationally representative estimates of induced abortion incidence and safety and evaluates the performance of the indirect measurement approach. We used cross-sectional, representative survey data on women aged 15-49 in Niger collected between January and May 2022; final sample included 3,696 women. The survey included questions on respondents' and their closest female friends' experience with abortion, including methods and sources used. We calculated one-year abortion incidence and the proportion of abortions involving non-recommended methods and/or sources to determine safety separately for respondents and friends, overall and by background characteristics. The fully adjusted one-year friend abortion rate was 6.7 abortions per 1,000 women in 2021, which was substantially higher than the corresponding respondent rate of 0.4 per 1,000 women. Confidence intervals were wide, but friend estimates suggest higher abortion rates among women in their 20s, those with secondary or higher education, and those with no children. Nearly all abortions were unsafe (97% respondents, 100% friends), involving non-recommended methods and/or sources. While abortion numbers were small, unsafe abortion appeared more common among older women, married women, those with children, and those residing in rural areas. Our findings indicate that, despite legal restrictions, some women undergo abortions in Niger at great risk to their physical safety. Ensuring adequate access to quality voluntary family planning services to prevent unintended pregnancy and postabortion care to treat complications is essential to reducing the risk of unsafe abortion in the country.

Self-reported abortion experiences in Ethiopia and Uganda, new evidence from cross-sectional community-based surveys

Unsafe abortion is a major contributor to maternal morbidity and mortality. To gain insight into the ways in which abortion restrictions and stigma may shape reproductive health outcomes, we present self-reported data on abortions in Ethiopia and Uganda and compare these findings across the two varying legal contexts. W investigate differences in sociodemographic characteristics by whether or not a woman self-reported an abortion, and we describe the characteristics of women's most recent self-reported abortion. In Ethiopia only, we classified abortions as being either safe, less safe, or least safe. Finally, we estimate minimum one-year induced abortion incidence rates using the Network Scale-Up Method (NSUM). We find that women who self-reported abortions were more commonly older, formerly married, or had any children compared to women who did not report an abortion. While three-quarters of women in both settings accessed their abortion in a health facility, women in Ethiopia more commonly used public facilities as compared to in Uganda (23.0% vs 12.6%). In Ethiopia, 62.4% of self-reported abortions were classified as safe, and treated complications were more commonly reported among least and less safe abortions compared to safe abortions (21.4% and 23.1% vs. 12.4%, respectively). Self-reported postabortion complications were more common in Uganda (37.2% vs 16.0%). The NSUM estimate for the minimum one-year abortion incidence rate was 4.7 per 1000 in Ethiopia (95% CI 3.9-5.6) and 19.4 per 1000 in Uganda (95% C 16.2-22.8). The frequency of abortions and low levels of contraception use at the time women became pregnant suggest a need for increased investments in family planning services in both settings. Further, it is likely that the broadly accessible nature of abortion in Ethiopia has made abortions safer and less likely to result in complications in Ethiopia as compared to Uganda.

Describing the safety of abortion at the population level using network-based survey approaches

BACKGROUND

Despite the negative impact of unsafe abortions on women's health and rights, the degree of abortion safety remains strikingly undocumented for a large share of abortions globally. Data on how women induce abortions (method, setting, provider) are central to the measurement of abortion safety. However, health-facility statistics and direct questioning in population surveys do not yield representative data on abortion care seeking pathways in settings where access to abortion services is highly restricted. Recent developments in survey methodologies to study stigmatized / illegal behaviour and hidden populations rely on the fact that such information circulates within social networks; however, such efforts have yet to give convincing results for unsafe abortions.

OBJECTIVE

This article presents the protocol of a study whose purpose is to apply and develop further two network-based methods to contribute to the generation of reliable population-level information on the safety of abortions in contexts where access to legal abortion services is highly restricted.

METHODS

This study plans to obtain population-level data on abortion care seeking in two Health and Demographic Surveillance Systems in urban Kenya and rural Burkina Faso by applying two methods: Anonymous Third-Party Reporting (ATPR) (also known as confidantes' method) and Respondent Driven Sampling (RDS). We will conduct a mixed methods formative study to determine whether these network-based approaches are pertinent in the study contexts. The ATPR will be refined notably by incorporating elements of the Network Scale-Up Method (NSUM) to correct or account for certain of its biases (transmission, barrier, social desirability, selection). The RDS will provide reliable alternative estimates of abortion safety if large samples and equilibrium can be reached; an RDS multiplex variant (also including social referents) will be tested.

DISCUSSION

This study aims at documenting abortion safety in two local sites using ATPR and RDS. If successful, it will provide data on the safety profiles of abortion seekers across sociodemographic categories in two contrasted settings in sub-Saharan Africa. It will advance the formative research needed to determine whether ATPR and RDS are applicable or not in a given context. It will improve the questionnaire and correcting factors for the ATPR, improve the capacity of RDS to produce quasi-representative data on abortion safety, and advance the validation of both methods.

Social Network-Based Induced Abortion Incidence Estimation in Burkina Faso: Examining the Impact of the Network Generating Question

Social network-based methods are increasingly used to estimate induced abortion incidence and investigate correlates. Approaches differ in the social tie definitions used to identify which social network members' abortion experiences respondents will report. This study compares the effect of using the "best friend" (closest female friend) versus "confidante" (specifying mutual sharing of personal information) definition on abortion incidence estimation. We use data from a nationally representative survey of women aged 15-49 in Burkina Faso (conducted in 2020-2021) where respondents were randomized into two versions of an abortion module, using different friend definitions. We computed abortion rate estimates by friend definition and adjusted for assumption violations (transmission bias, surrogate sample selection bias). Unadjusted incidence rates varied from 11.7 [4.1-19.2] abortions per 1,000 women to 15.6 [9.7-21.4], depending on friend definition. The confidante definition yielded higher adjusted estimates (36.2 [25.1-47.2]) than the best friend definition (17.0 [8.7-25.3]) due to greater transmission bias adjustment. Both estimates exceeded the respondent self-reported abortion incidence (4.0 [2.2-5.9]). Our results indicate that either friend definition produces higher incidence estimates than self-report but suggest a potential advantage for the "best friend" over the "confidante" definition given lower transmission bias. Further research should assess generalizability of these findings in other contexts.

An investigation of the impact of the Global Gag Rule on women's sexual and reproductive health outcomes in Uganda: a difference-in-differences analysis

In 2017, the Trump administration reinstated the Global Gag Rule (GGR), making non-U.S. non-governmental organisations ineligible for US government global health assistance if they provide access to or information about abortion. Little is known about the impact of the Trump administration's GGR on women's outcomes. Data for this analysis come from a panel of women surveyed in 2018 and 2019 in Uganda (n = 2755). We also used data from meetings with key stakeholders to create a detailed measure of exposure to the GGR within Uganda, classifying districts as more or less exposed to the GGR. Multivariable regression models were used to assess changes in contraceptive use, all births, unplanned births, and abortion from before to during implementation of the GGR. Difference-in-differences (DID) estimates were determined by calculating predicted probabilities from interaction terms for exposure/survey round. Descriptive analyses showed long-acting reversible contraceptive use increased more rapidly among women in less exposed districts after GGR implementation. DID estimates for contraceptive use were small. We observed a DID estimate of 3.5 (95% CI -0.9, 7.9) for all births and 2.9 (95% CI -0.2, 6.0) for unplanned births for women in more exposed districts during the period the policy was in effect. Our results suggest that the GGR may have attenuated Uganda's recent progress in improving SRHR outcomes, with women in less exposed districts continuing to benefit from this progress, while previously increasing trends for women in more exposed districts levelled off. Although the GGR was rescinded in January 2021, the impact of these disruptions may be felt for years to come.

Induced abortion incidence and safety in Burkina Faso in 2020: Results from a population-based survey using direct and social network-based estimation approaches

This study aims to estimate induced abortion incidence and safety in Burkina Faso using direct and indirect methods, overall and by women's background characteristics. Data come from a nationally representative survey of reproductive aged women (n = 6,388). To address social desirability bias in abortion reporting, we asked about respondents' closest female friends' experience with abortion. The one-year abortion incidence in 2020 for respondents was 4.0 (95% CI 2.2-5.9) per 1,000 women aged 15-49 while the adjusted friend incidence was 22.9 (95% CI 15.8-30.0). Although not significant, abortion incidence was higher for adolescents, unmarried women, those with higher education, and those in urban areas among both respondents and their friends. Approximately nine out of ten abortions were unsafe (90% respondents, 95% friends), with respondent and friend findings suggesting higher risk of unsafe abortion among older women, less educated women, and women residing in rural areas. Despite recent increases in contraceptive use and continued legal restrictions, abortion remains common in Burkina Faso and is largely unsafe, with evidence of potential disparities.
