Hai-Yen Sung, Ph.D. is Associate Adjunct Professor at the Institute for Health & Aging and the Department of Social and Behavioral Sciences.
She received her Ph.D. in Agriculture Economics from the University of California, Berkeley where she was also a NIA postdoctoral fellow in Economics of Aging and Health Services Research.
Dr. Sung's research activities have focused on the economics of tobacco control and policy, cancer screening and outcomes, and economic costs of illness and smoking. Examples of tobacco control research include assessing the effects of taxation, anti-smoking media campaign, regulation, tobacco industry's advertising, over-the-counter nicotine replacement drugs, and national tobacco settlement on cigarette smoking; examining the relationship among the use of smoking cessation programs, smoking cessation behavior, and medical care utilization and costs.
Examples of cancer and outcomes research include the effects of screening intervals and follow-up on the risk of cervical cancer incidence among HMO enrollees; evaluation of quality of care for HMO members with chronic conditions, and risk-adjusted hospital outcomes.
Examples of costs of illness research include estimating the direct and indirect costs of chronic illness, osteoporosis, gender-specific cancers, and smoking.
Title: Cigarette Price Sensitivity of Smokers with Comorbid Alcohol, Drug, or Mental
Disorders
Project Period: 3/01/07-2/29/08
(Co-Investigator)
Funding Agency: Robert
Wood Johnson Foundation, Substance Abuse Policy Research Program
Description: The
goals of this project are to (1) determine if the price elasticity of
cigarette smoking participation among individuals with comorbid alcohol,
drug, or mental (ADM) disorders differs depending on the specific
comorbidity, and (2) determine whether factors, such as treatment of ADM
disorders, exist that increase the likelihood that smokers with comorbid
ADM disorders will quit following a cigarette tax increase.
Title: Tobacco Control Policy Analysis & Intervention Evaluation in China
Project Period: 7/01/02-6/30/07
(Co-Investigator)
Funding Agency: NIH,
Fogarty International Center
Description: This
project aims to increase research capacity among Chinese researchers on
tobacco control and evaluation research with collaborators from
University of California, the World Bank, Chinese Ministry of Health,
Chinese Center for Disease Control and Prevention, Sichuan University,
Fudan University, and Beijing University. Studies will examine the
economic costs of smoking, the environmental risks of smoking, the
impact of tobacco control and international trade policies on China's
cigarette consumption, tobacco agricultural sector and tobacco industry,
and the cost-effectiveness of tobacco control interventions.
Title: The Disproportionate Cost of Smoking for Communities of Color
Project Period: 7/1/2004-6/30/2006 (Co-Investigator)
Funding Agency: California Tobacco-Related Disease Research
Program
Description: The purpose of this project is to estimate
smoking-attributable costs for African Americans, Hispanics, and others
in California for 2002 with three specific aims are to estimate (1) the
direct costs of smoking-related illness, (2) the value of lost
productivity from smoking-related illness, and (3) losses resulting from
smoking-caused mortality.
Title: Smoking Cessation and Medical Care Use/Costs in a Large HMO
Project Period: 7/1/03-6/30/06
Funding Agency: California Tobacco-Related Disease Research Program
Description: This study examines the association between the use
of smoking cessation programs and individual's smoking cessation
behavior, and assesses the impact of smoking cessation on medical care
utilization and costs among members of a large managed care health plan
in Northern California. It also determines if excess costs are incurred
by current smokers and former smokers compared with never smokers, if
the magnitude of excess costs by former smokers diminishes over time
after quitting, if the excess costs are mainly caused by treating
tobacco-related diseases, and if there are gender-specific differences
in the excess costs.
Title: The Cost of Breast Cancer in California
Project Period: 7/1/2003-6/30/2006 (Co-Investigator)
Funding Agency: California Breast Cancer Research Program
Description: The
purpose of this research is to estimate (1) the annual cost of breast
cancer in California, including direct health care costs, (2) the value
of lost productivity for those living with the disease, and (3) the
value of lives lost prematurely.
