Understanding contraceptive decision-making, use and pregnancy outcomes
We study people's knowledge and perceptions of different methods of contraception, preferences and method choice, contraceptive use and continuation, and pregnancy and other health, economic and social outcomes, especially for underserved populations including adolescents. Our research informs public policy and programmatic efforts to promote contraceptive awareness, access, reproductive autonomy, and health equity.
We employ mixed methods, including survey research, medical records review, focus groups, in-depth interviews and policy analysis, to identify gaps in knowledge and to better understand patient preferences and the factors that influence contraceptive decision-making, including the role of health care providers, partners, and social support. We investigate disparities in contraceptive use and pregnancy outcomes by race, ethnicity, age and socioeconomic groups. Understanding these complex issues is essential to the development of effective programs and policies to advance health equity and improve public health outcomes.
