DHS considers each episode of use contributed by a woman in the calendar to calculate method discontinuation. This means that episodes from women who contribute only one episode of contraceptive use are combined with episodes from women who contribute multiple episodes of use. This paper explores the DHS calculation of episode-based discontinuation and proposes new indicators that focus specifically on the client and puts her as the unit of analysis. First, we attempt to replicate the DHS calculation by applying weighted averages to episodes from women who contributed only one episode and from women who contributed multiple episodes of use. We then calculate three client-centered discontinuation indicators, using the five-year calendar data of the DHS. The methodology is illustrated by using data collected in Bangladesh, Kenya, and Indonesia. Starting with the very first method used and reported in the calendar and following use over 12 months, we develop a client-centered discontinuation indicator. We build on the calculation of the client-centered discontinuation indicator by: (1) excluding switching to result in all contraceptive discontinuation (complete discontinuation); and (2) limiting discontinuation to women still in need of contraception applying the DHS definitions of in need.</p>","PeriodicalId":22069,"journal":{"name":"Studies in Family Planning","volume":"53 4","pages":"681-693"},"PeriodicalIF":2.1,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10538042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although conceptually straightforward, its estimation suffers from a number of methodological limitations, most notably its reliance on biased measures of women's stated fertility preferences. We propose a counterfactual-based approach to measuring unmet need at the population level. Using data from 56 countries, we calculate unmet need in a population as the difference between: (1) the observed contraceptive prevalence in the population; and (2) the calculated contraceptive prevalence in a subsample of women who are identified to be from \"ideal\" family planning environments. Women from \"ideal\" environments are selected on characteristics that signal their contraceptive autonomy and decision-making over family planning. We find significant differences between our approach and existing methods to calculating unmet need, and we observe variation across countries when comparing indicators. We argue that our indicator of unmet need is preferable to existing population-level indicators due to its independence from biases that are generated from the use of reported preference measures, the simplicity with which it can be derived, and its relevance for cross-country comparisons as well as context-specific analyses.</p>","PeriodicalId":22069,"journal":{"name":"Studies in Family Planning","volume":"53 4","pages":"657-680"},"PeriodicalIF":2.1,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/79/2f/SIFP-53-657.PMC10107817.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9690052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Already stressed maternal health services were deeply affected by the outbreak due to fears of viral transmission, reallocation of maternity staff, and broader policies to stop transmission including travel restrictions. This research sought to explore women's perspectives on delaying pregnancy during the Ebola outbreak using family planning methods. Qualitative data collection took place in Kambia District in 2018 and included 35 women participants, with women who were either family planning users or nonusers at the time of the outbreak. Women reported a variety of reasons for choosing to take or not to take family planning during the outbreak, which we categorized as proximal (directly related to the outbreak) or distal (not directly outbreak related). Proximal reasons to take family planning included to avoid interacting with health care spaces where Ebola could be transmitted, to avoid the economic burden of additional children in a time when economic activities were curtailed and to return to school when education resumed postoutbreak. Distal reasoning included gender roles affecting women's decision making to seek family planning, concerns related to the physiological side effects of family planning, and the economic burden of paying for family planning. Women's perspectives for choosing to take or not take family planning during the Sierra Leone Ebola crisis had not been explored prior to this paper. Using the lens of family planning to consider how women choose to access health care in an outbreak gives us a unique perspective into how all health care interactions are impacted by a generalized outbreak of Ebola, and how outbreak responses struggle to ensure such services remain a priority.</p>","PeriodicalId":22069,"journal":{"name":"Studies in Family Planning","volume":"53 4","pages":"575-593"},"PeriodicalIF":1.9,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10086979/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9286121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The region also has the highest rate of unintended pregnancy of any world region, and nearly half of such pregnancies end in abortion. However, fewer than 18 percent of the region's women live in countries where abortion is broadly legal. This paper estimates the causal effect of abortion legalization on adolescent fertility in Uruguay using official data on legal abortions provided after the 2012 reform. We employed a difference-in-differences strategy, classifying states by whether they are responsive or unresponsive to the reform. The results suggest that abortion reform had a negative impact on the adolescent birth rate by 2.5-2.8 births per thousand adolescents aged 15-19 (a 4 percent decrease from the preintervention average). Additionally, we exploited variation in reform implementation intensity through the estimation of fixed-effect linear regression models and found consistent results. Our findings are robust to controlling for a concurrent large-scale program of contraceptive implants. We conclude that legislation aimed at enhancing rights and reducing avoidable deaths and complications from unsafe abortions may also have spillover effects that help reduce adolescent fertility.</p>","PeriodicalId":22069,"journal":{"name":"Studies in Family Planning","volume":" ","pages":"491-514"},"PeriodicalIF":2.1,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40404716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we analyze changes in the rich-poor gaps in modern contraceptive prevalence (mCP) in urban Africa over time. We then determine the public source of the supply of modern contraceptives to the urban poor and how that supply may have changed over a 10-year period. The findings show that, in most Eastern and Southern African countries, previous gaps in mCP between the rich and poor married women have disappeared. Countries in Central and Western Africa, however, continue to have significant gaps in mCP between rich and poor women, with urban poor women experiencing only a modest improvement in mCP over the past decade.
