The lack of validated, cross-cultural measures for examining quality of contraceptive counseling compromises progress toward improved services. We tested the validity and reliability of the 10-item Quality of Contraceptive Counseling scale (QCC-10) and its association with continued protection from unintended pregnancy and person-centered outcomes using longitudinal data from women aged 15-49 in Burkina Faso, Kenya, and Nigeria. Psychometric analysis showed moderate-to-strong reliability (alphas: 0.

Importance: COVID-19 racial disparities have gained significant attention yet little is known about how age distributions obscure racial-ethnic disparities in COVID-19 case fatality ratios (CFR).

Objective: We filled this gap by assessing relevant data availability and quality across states, and in states with available data, investigating how racial-ethnic disparities in CFR changed after age adjustment.

Design/setting/participants/exposure: We conducted a landscape analysis as of July 1st, 2020 and developed a grading system to assess COVID-19 case and death data by age and race in 50 states and DC.

Background: The remarkable growth of cell phone ownership in low- and middle-income countries has generated significant interest in using cell phones for conducting surveys through computer-assisted telephone interviews, live interviewer-administered surveys, or automated surveys (ie, interactive voice response).

Objective: This study aimed to compare, by mode, the sociodemographic characteristics of cell phone owners who completed a follow-up phone survey with those who did not complete the survey.

Methods: The study was based on a nationally representative sample of women aged 15 to 49 years who reported cell phone ownership during a household survey in Burkina Faso in 2016.

Estimated use of emergency contraception (EC) remains low, and one reason is measurement challenges. The study aims to compare EC use estimates using five approaches. Data come from Performance Monitoring and Accountability 2020 surveys from 10 countries, representative sample surveys of women aged 15 to 49 years.

Article Synopsis
  • The Family Planning 2020 (FP2020) initiative was launched in 2012 with the goal of increasing modern contraceptive use among 120 million women in the 69 poorest countries by 2020, requiring significant growth in contraceptive prevalence rates.
  • Researchers analyzed trends in contraceptive use in nine settings across eight sub-Saharan African countries using data from 45 rounds of PMA2020 surveys post-2012, focusing on women aged 15-49.
  • The study used statistical models to estimate changes in contraceptive prevalence rates, revealing insights into the effectiveness of the initiative in different regions.

Objectives: With over 420 million unique cell phone subscribers in sub-Saharan Africa, the opportunities to use personal cell phones for public health research and interventions are increasing. We assess the association between cell phone ownership and modern contraceptive use among women in Burkina Faso to understand the opportunity to track family planning indicators using cell phone surveys or provide family planning interventions remotely.

Study Design: We analyzed data from a cross-sectional, nationally representative population-based survey of women of reproductive age in Burkina Faso, the Performance Monitoring and Accountability 2020 Round 4, which was conducted between November 2016 and January 2017.

Objective: Measuring current use of contraception relies on self-reported responses from survey respondents. Reporting validity may be affected by women's interpretation of the question and may vary by background characteristics of women. The study aims to understand levels and patterns of underreporting of female sterilization in a population with high sterilization rates.

Objectives: Equality is a central component of the Sustainable Development Goals (SDGs). We took one SDG indicator and benchmark-percent of family planning demand met with modern contraceptives, with a benchmark of at least 75% in all countries-as a case study to illuminate recommendations for monitoring equality. Specifically, we assessed levels, patterns, and trends in disparity by key background characteristics and identified disparity measures that are programmatically relevant and easy to interpret.

Background: Meeting demand for family planning can facilitate progress towards all major themes of the United Nations Sustainable Development Goals (SDGs): people, planet, prosperity, peace, and partnership. Many policymakers have embraced a benchmark goal that at least 75% of the demand for family planning in all countries be satisfied with modern contraceptive methods by the year 2030.

Objective: This study examines the demographic impact (and development implications) of achieving the 75% benchmark in 13 developing countries that are expected to be the furthest from achieving that benchmark.

The subcutaneous (SC) injectable, widely known by its commercial name Sayana Press, has potential to improve access to contraceptive methods. In Burkina Faso, SC-injectables were first piloted in select regions in 2014 and introduced nationally in 2016. PMA2020 is the first national survey to track programmatic progress of SC-injectable introduction at both population and health facility levels in the country across 2 rounds of data collection: March-May 2016 and November 2016-January 2017.

With growing attention to monitoring and improving quality of care, it is critical to have evidence-based recommendations to measure quality of care indicators and guidelines to interpret estimates from different data sources. This study facilitates methodological discussion regarding measurement of counseling for side effects in family planning, a critical component of quality. The study assesses and compares estimates of side effects counseling based on three data sources.

The government of Nepal revised its law in 2002 to allow women to terminate a pregnancy up to 12 weeks gestation for any indication on request, and up to 18 weeks if certain conditions are met. We evaluated the readiness of facilities in Nepal to provide three abortion services, manual vacuum aspiration (MVA), medication abortion (MA) and post-abortion care (PAC), using the service availability and readiness assessment (SARA) framework. The framework consists broadly of three domains; service availability, general service readiness and service readiness specific to individual services (i.

Expanding access to family planning (FP) is a driving aim of global and national FP efforts. The definition and measurement of access, however, remain nebulous, largely due to complexity. This article aims to bring clarity to the measurement of FP access.

Background: In order to track progress towards the target of universal access to sexual and reproductive health care services of the post-2015 Sustainable Development Goals (SDGs), a measure (demand for family planning satisfied with modern contraceptive methods) and a benchmark (at least 75% by 2030 in all countries) have been recommended.

Objectives: The goal of this study was to assess the prospects of reaching the benchmark at the country level. Such information can facilitate strategic planning, including resource allocation at global and country levels.

Background: The etiology of >90% of cases of suspected neonatal infection remains unknown. We conducted community-based surveillance in conjunction with hospital-based surveillance in a rural region in Bangladesh from June 2006 to September 2007 to assess the incidence and etiology of community-acquired viral infections among neonates.

Methods: Community health workers (CHWs) assessed neonates at home on days 0, 2, 5 and 8 after birth and referred cases of suspected illness to the hospital (CHW surveillance).

This study assesses the quality of Demographic and Health Survey (DHS) data regarding self-reported current use of the lactational amenorrhea method (LAM). LAM is an important modern contraceptive method that, when practiced correctly, has a 98 percent effectiveness rate six-months postpartum. The objectives of this study are to examine the accuracy of self-reported LAM use, compared with the constructed correct-practice variable, and to explore differentials in accuracy measures by characteristics at the individual and survey level by analyzing data from 73 DHSs conducted in 45 countries between 1998 and 2011.

Infection is the major cause of neonatal deaths. Home born newborns in rural Bangladeshi communities are exposed to environmental factors increasing their vulnerability to a number of disease agents that may compromise their health. The current analysis was conducted to assess the association of very severe disease (VSD) in newborns in rural communities with temperature, rainfall, and humidity.
