  • Impacts of Contraception on Future Fertility: Addressing Concerns to Improve Understanding

    Open AccessLorna Begg, Onikepe O Owolabi et al.ARTICLEStudies in Family Planning2026

    Even though one‐year pregnancy rates following contraceptive discontinuation are similar to pregnancy rates following nonuse of contraception, there are widespread perceptions that modern contraceptives will have adverse effects on future fertility. There are likely a variety of factors that contribute to these perceptions. One explanation could be the short‐term (

  • The association between female genital cutting and time-to-pregnancy among women of reproductive age – applying the current duration approach in demographic and health survey data from Nigeria

    Open AccessLaura Briggs Drew, Chelsea B Polis et al.ARTICLECulture Health & Sexuality2026

    Female genital cutting (FGC) may lead to clinical infertility (failure to achieve a pregnancy after 12 months of regular unprotected sexual intercourse) through gynaecologic morbidity and reduced sexual frequency, but previous studies were inconclusive. Therefore, we examined if FGC and FGC severity were associated with longer time-to-pregnancy (TTP) in Nigeria. We restricted 2013 Nigeria Demographic Health Survey (NDHS) data to women at risk of …

  • Estimating the incidence of abortion: Using the Abortion Incidence Complications Methodology in Ghana, 2017

    Open AccessChelsea B Polis, Philicia W Castillo et al.ARTICLEBMJ Global Health2020

    Introduction: Induced abortion is legally permitted in Ghana under specific conditions, but access to services that meet guidelines approved by government is limited. As part of a larger project comparing five methodologies to estimate abortion incidence, we implemented an indirect estimation approach: the Abortion Incidence Complications Methodology (AICM), to understand the incidence of abortion in Ghana in 2017. Methods: We drew a nationally r…

  • Estimating the incidence of abortion: A comparison of five approaches in Ghana

    Open AccessSarah C Keogh, Sarah Keogh et al.ARTICLEBMJ Global Health2020

    Introduction Induced abortion estimates are critical for reproductive health programming. In countries like Ghana where abortion is somewhat legally restricted and highly stigmatised, official records are incomplete and different approaches are needed to measure abortion incidence. We conducted a study in Ghana to test five methodologies for estimating incidence: direct reporting, the list experiment, the confidante method, the Abortion Incidence…

  • Perceived Infertility Among Young Adults in Balaka, Malawi

    Chelsea B Polis, Polis Polis et al.ARTICLEInternational Perspectives on…2020

    CONTEXT: Perceived infertility-an individual's belief that she or he is unable to conceive or impregnate a partner-may lead to contraceptive nonuse and unintended pregnancy, among other concerns, but has not been widely studied in low-income settings. METHODS: A measure of perceived infertility previously used in the United States was included in a 2015 survey of young adults in Balaka, Malawi. The prevalence of potential perceived infertility (i…

  • Prevalence and Correlates of Perceived Infertility in Ghana

    Open AccessChelsea B Polis, Easmon Otupiri et al.ARTICLEStudies in Family Planning2020Cited by: 3References: 37

    Perceived infertility is an understudied phenomenon in low‐ and middle‐income countries, where biomedical infertility can have severe consequences, particularly for women. We conducted a nationally representative survey of Ghanaian women, estimated the prevalence of and reasons for perceived infertility, and assessed factors associated with higher levels of perceived infertility using a partial proportional odds model. Among 4,070 women, 13 perce…

  • Global Contraceptive Failure Rates: Who Is Most at Risk

    Open AccessSarah E K Bradley, Sarah E Bradley et al.ARTICLEStudies in Family Planning2019Cited by: 11References: 21

    Contraceptive failure is a major contributor to unintended pregnancy worldwide. DHS retrospective calendars, which are the most widely used data source for estimating contraceptive failure in low‐income countries, vary in quality across countries and surveys. We identified surveys with the most reliable calendar data and analyzed 105,322 episodes of contraceptive use from 15 DHSs conducted between 1992 and 2014. We estimate contraceptive method‐s…

  • Using Measurements of Unmet Need to Inform Program Investments for Health Service Integration

    Open AccessShawn Malarcher, Chelsea B PolisARTICLEStudies in Family Planning2014Cited by: 3References: 7

    Demographic and Health Survey (DHS) data could potentially inform optimal strategies to reach women having unmet need with contraceptive services through integrated service delivery. Using 2010–11 DHS data from Nepal, Senegal, and Uganda, we estimate the proportion of married or cohabitating women of reproductive age (MWRA) having unmet need for family planning (FP) who have accessed selected health services and therefore could be offered FP serv…
