Study
What is the purpose?
The COBRA study investigates changes in body composition, which is the amount of adipose and muscular tissue, of women with breast cancer who are treated with or undergoing chemotherapy. Therefore, we study how women experience possible changes in diet, physical activity and quality of life during treatment and which suggestions they have in order to prevent those changes. Women who have not been diagnosed with breast cancer are also included in this study in order to determine which body changes are caused by chemotherapy and which effects occur in “healthy” women of the same age group.
 
What does that involve?
The COBRA study is an observational study, which means that the researchers collect data without an intervention. The study consists of two research methods: quantitative and qualitative. In the quantitative research of the study all participants undergo body measurements, donate blood samples and fill out questionnaires. For the qualitative research of the study a smaller group of participants is invited to take part in interviews, and after the interviews focus groups will be organized. Participants will be monitored for a period of one year.
 
Who can participate?
For women with breast cancer participation in the COBRA study is possible if they are having chemotherapy at one of the cooperating hospitals. Women without breast cancer can only participate in the study if they are invited by a participating woman with breast cancer and if they meet the inclusion criteria.
