Dr. Lim's research involves the epidemiologic investigation of nutrition and lifestyle risk factors and related racial/ethnic heterogeneity in cancer etiology. In particular, she is interested in understanding the carcinogenic effects of obesity and body fat distribution and how they vary across racial/ethnic populations. Obesity is becoming the leading risk factor for cancer, contributing to the development of over a dozen types of cancer. Combined disease burden of obesity or excess body fatness is estimated to be responsible for $150 billion in annual medical care and about 20% of all deaths in the U.S. Additionally, the detrimental metabolic effects of excess body fat is known to be greater when it is stored in the abdominal and intra-abdominal regions than in peripheral and sub-cutaneous regions. In the Multiethnic Cohort Study, Dr. Lim and colleagues have observed that Asian Americans, along with Latinos and Native Hawaiians, have a greater propensity to accumulate intra-abdominal fat in the viscera, liver, and pancreas, compared to whites or African Americans. In collaboration with multidisciplinary researchers, Dr. Lim is investigating additional disease burden from the high-risk fat depots, biomarkers for understanding their metabolic effects, and lifestyle interventions to improve the adiposity and metabolic profiles.
