Evidence from health emergencies suggests COVID-19 will disrupt women's sexual and reproductive (SRH). In sub-Saharan Africa, which experiences the highest rates of unintended pregnancy unsafe abortion globally, is projected to slow recent progress toward universal access contraceptive services.We used longitudinal data collected women at risk in Burkina Faso (n=1186) Kenya (n=2784) before (November 2019-February 2020) during (May-July quantify dynamics COVID-19; examine sociodemographic...

Understanding contraceptive use dynamics is critical to addressing unmet need for contraception. Despite evidence that male partners may influence decision-making, few studies have prospectively examined the supportive ways men women's and continuation.This study sought understand predictive effect of partner influence, defined as partner's fertility intentions support contraception, discussions about avoiding pregnancy prior use, on (continuation, discontinuation, switching, adoption) over...

The individual impacts of several components family planning service quality on contraceptive use have been studied, but the influence a composite measure synthesizing these has not often investigated. We (1) develop score for based health facility data from Burkina Faso, Ethiopia, Kenya and Uganda (2) examine structural practice in four countries. used nationally representative cross-sectional survey facilities women reproductive age.

The importance of the family planning service environment and community-level factors on contraceptive use has long been studied. Few studies, however, have able to link individual health facility data from surveys that are nationally representative, concurrently fielded, geographically linked. Data Performance Monitoring Accountability 2020 address these limitations. To assess relative influences delivery community, household, a woman's likelihood using modern in five culturally diverse...

Health priorities since the UN Millennium Declaration have focused strongly on children younger than 5 years. The health of older (age 5-9 years) and adolescents 10-14 has been neglected until recently, especially in low-income middle-income countries, mortality measures for these age groups often derived from overly flexible models. We report global regional empirical estimates aged 5-14 years compare them with ones existing models.For this analysis, we obtained birth-history data surveys...

Abstract Norms and beliefs toward contraception, both positive negative, motivate contraceptive use; however, they have seldom been explored longitudinally in low‐ middle‐income countries, limiting our understanding of their influence on dynamics. We used PMA2020 Uganda national longitudinal data reproductive aged women 2018 (baseline) 2019 (follow‐up) to explore discontinuation switching among modern users at baseline (n = 688) use follow‐up nonusers 1,377).
