Abstract
My experience work on the PENN Ovarian Aging Study (POAS) has contributed to my career in many ways. In this talk I describe how my work on this project has shaped my views on team science and collaboration. I will illustrate some examples of how this research team has influenced my interests and methodological contributions.
POAS tracked a population-based cohort of pre-menopausal women age 35-47 years over 14 years to determine associations between reproductive hormones and menopausal symptoms. Well timed annual visits over the study period afforded a unique opportunity to examine not only longitudinal trends in hormones over the menopausal transition but allowed us to examine the question of whether fluctuations in hormones contribute to symptom onset. I will describe the development of a joint modeling approach that utilizes individual-level longitudinal measurements of follicle stimulating hormone (FSH) to predict the risk of severe hot flashes. In this work we developed two approaches, a shared random effects and a latent class framework for the primary-outcome model. Simulation studies are developed to compare and contrast model performance.
Key words: Joint model; Latent class; Long-term trend; Short-term variability
