详细描述
Questionnaire:
If you agree to take part in this study, you will complete a questionnaire about your family's characteristics. For example, the questionnaire will have questions about your educational level, your eating habits, your health conditions, your family's income level, and how many people live in your house. The study doctor will also ask you questions about any drugs you may be taking. The questionnaire should take about 30-35 minutes to complete.
The completed paper questionnaire will be placed in a secured, locked cabinet and will be given a code number. Only the researcher in charge of the study will have access to the code numbers and be able to link the questionnaire to you. After the study ends and after information from the questionnaire has been entered in a password protected database, the paper copy of the questionnaire will be sent to M. D. Anderson to be stored for up to 5 years. After 5 years, it will be destroyed.
Urine Sample:
You will have a urine sample collected. Researchers will study the urine samples to learn what your level of exposure may be to certain chemicals in the environment, specifically chemicals called phthalates. Phthalate is the only chemical that will be measured.
