Promoting access to contraception, safe abortion, and new technologies globally

Our research contributes to science, clinical practices, and policy globally in low-resource settings where maternal mortality is high. Our global work focuses on access to contraception, safe abortion, and the integration of new prevention technologies into clinical practice.

We have worked closely with the Center for Research on Environment Health and Population Activities (CREHPA), a leading research organization in Nepal, to document improvements to women’s health over the past decade in Nepal. Our research showed a decline in the severity of abortion complications at hospitals following abortion legalization in 2004. Other studies have demonstrated ongoing barriers to safe abortion and contraceptive care, including widespread use of unsafe medications and attitudinal and structural barriers.

Our research in Mexico has focused on providers' and potential users’ knowledge, perceptions, and experiences with abortion and contraceptive services.

In sub-Saharan Africa, we conducted an NIH-funded R01 to assess the integration of new contraceptive and HIV prevention technologies into clinical practices. Our results guide efforts to integrate novel prevention methods, including microbicides, male circumcision, and long-acting reversible contraceptives, into patient education, counseling, and service delivery.
