## Abstract

PROJECT SUMMARY
Over the past three decades, extensive health, economic, and social costs have been associated with obesity.
Children from disadvantaged backgrounds are more likely to be obese, with weight gain in childhood
continuing into adulthood and resulting in the early onset of cardiovascular disease. Such adverse effects are
pronounced among women than men. Gender differences are also evident in socioeconomic opportunities,
psychosocial resources, and emotional/behavioral coping strategies, suggesting that there may be gender-
driven psychosocial, behavioral, and biological, e.g., genetic and reproductive, mechanisms linking early life
adversities (ELAs) to obesity and cardiovascular risk. Nonetheless, some individuals who have experienced
ELAs do not succumb to cardiovascular risk; they may leverage individual psychosocial resources to halt or
reverse accumulated disadvantages from childhood, although the availability of such resources may also vary
by gender. Few studies have employed an integrative approach to understanding the broader set of influences
on gender differences in obesity and cardiovascular risk. The overall goal of this Pathway to Independence
Award is to provide the PI with the interdisciplinary training and research experience needed to investigate how
ELAs affect body weight and cardiovascular risk, via the interplay of psychosocial, behavioral, and biological
mechanisms, while characterizing gender differences throughout the analysis. Having previously worked as a
nurse in South Korea, the PI brings front-line experience to the task of understanding health disparities. During
her subsequent training and research in sociology and population health science, she applied theories of social
determinants of health to multiple nationally representative data sets. The PI is well along the path to becoming
a leading researcher on gender, life adversities, and health. During the K99 phase, the PI seeks training and
mentoring to broaden her focus beyond social perspectives to include epidemiological and psychological
knowledge of (1) causal inferences in behavioral obesity research (including co-twin control analyses), (2)
cardiovascular disease, (3) reproductive health, and (4) resilience. During the R00 phase the PI will develop an
integrative life-course approach to study the gender-specific pathways through which ELAs affect risk of adult
obesity and cardiovascular disease by combining her primary expertise in sociology with additional
epidemiological and psychological knowledge. The proposed research will be based on a nationally
representative longitudinal data set, known as MIDUS (Midlife in the United States), which began with 7,108
adults, including 998 twin dyads. Findings from the PI's research should be relevant for development of
gender-specific interventions to reduce the risk of obesity and cardiovascular disease, particularly for
individuals who have experienced adversities in early life.
