Cancer Epidemiology
- Since 1992, the Takayama study, a cohort study comprised of approximately 30,000 residents in the Gifu Prefecture city of Takayama, has been conducted. The primary objective of the Takayama study is to investigate associations of diet and other lifestyle factors with cancer and other chronic diseases.
- Lifestyle or the environment early in life may be relevant to the risk of breast cancer during adulthood. This study includes preschool and school children to explore the links between lifestyle or environmental factors and urinary estrogen and melatonin levels.
- We are part of the International Pooling Project of Mammographic Density coordinated by the International Agency for Research on Cancer (PI: Dr. Valerie McCormack), and A Pooled Analysis of Mammographic Density and Breast Cancer Risk, coordinated by University of Hawaii Cancer Center (PI: Dr. Gertraud Maskarinec).
- Risk factors of heart disease, stroke, diabetes, hyperlipidemia, hypertension, cataracts, and allergies have been investigated using cohort studies or cross-sectional studies.
- A cohort study among primary school children has been initiated. The study evaluates the associations of diet and lifestyle with obesity and blood glucose and lipids levels. This knowledge can enable scientists to develop solutions to help reduce the risk of developing lifestyle-related diseases in adulthood.
- Soybeans are the predominant source of isoflavones, which possess estrogenic properties. The potential role of soy in the etiology of hormone-related diseases or conditions is being studied.
- Accurate measurement of children’s diet is essential for investigating the nutritional habits of children. We develop food frequency questionnaires to use among children and young people and undertake research to utilize them for dietary education.
