Research Focus

Dr. Novotny's research focus is in ethnic differences in diet, physical activity and body size and composition, especially patterns of growth and development, using anthropometry and DXA. She and colleagues have shown that Asian adolescent girls carry more trunk to peripheral DXA body fat than white girls, and that birth weight and birth length are inversely related to this relationship. They have also developed a novel measure of breast density, using DXA, which they are examining in girls and their mothers; and they are building a breast cancer risk model for Pacific Islanders that will expand the Gail model with novel risk factors. She was recently awarded a multi-million dollar multi-institutional grant to prevent child obesity throughout the Pacific Region.
