PARENT STUDY PAGE

Thank you for being part of Gemini for the last 11-12 years. Please find the links for the online parent questionnaire and game below. If possible, try to complete the whole questionnaire (35 to 40 minutes) and the online game (10 minutes) in a single session. Please complete the questionnaire on a laptop, a desktop or a tablet. Please do not do the online game on a mobile phone or a tablet.

Body measurements

In the questionnaire we will ask you to measure your and your twins'waist circumferences using the tape measure and instructions we sent you by post. You will also need to have measured the twins’ heights and weights and to have made a note of all the measurements before completing the questionnaire so you can enter them when prompted. Watch the short instruction video on the right which shows you how to measure waist circumference correctly.
