Dr. William McCarthy's current research includes lifestyle change prevention trials involving low-income Latinos and a comparative effectiveness trial pitting two government-sanctioned approaches to weight control, also involving predominantly low-income, immigrant Latino adult patients of a local community health center. McCarthy continues to contribute to the tobacco control literature, including recent research on adolescent electronic cigarette use. He has conducted epidemiological studies of tobacco use and tobacco use cessation patterns among adults and school age children, as well as diet and exercise patterns among African-American women and low-income children.
His past research includes the evaluation of California's SB 19 Pupil Nutrition Act, the evaluation of the tobacco prevention education efforts in California's public schools, statewide surveillance of tobacco use among residents of Asian/Indian ancestry and a county-wide intervention to reduce tobacco use among the residents of 26 transitional shelters for the homeless. Past research projects examined tobacco use among Asian subgroups, smoking cessation in low-income, pregnant women and a series of studies regarding mentholated cigarettes.
