Baseline Characteristics

Members of the genetic testing service MYCODE who have given consent for research to be conducted using samples and information obtained through MYCODE

Participant flow

Among the members of the genetic testing service MYCODE, those who have given their consent to the research to be conducted using the samples and information obtained through MYCODE will be invited to participate in the study through web and email notifications. Members will review the explanatory content of the study, including the consent explanatory document, on the web and, if they fully understand the content and are willing to participate voluntarily, they will express their consent on the web. This consent is carried out on a webpage displayed exclusively for members, where they can log in by entering their MYCODE registered email address, password and secret question, and where only they can view the webpage. There will also be a contact point for any questions regarding the study. If you do not consent to participate, you will not be disadvantaged because of this. After obtaining consent for the study, participants will be asked to complete an application questionnaire on a subsequent webpage concerning items related to vegetable preferences and the selection criteria for the test to measure skin carotenoid concentrations, as well as the possible test dates for participation. A target of 550 research subjects will be selected who meet the selection criteria and who have been judged by Kagome and DLS (business unit) to have no problems participating in the study. The research subjects will be notified by email from the DLS (business unit) and invited to visit the study site. Those who are not selected as research subjects will also be informed by the DLS (business unit), at which point their participation in the study will be terminated. Study subjects will have their skin carotenoid levels measured at the study site using Vegicheck. Study subjects will also be notified in advance by email about the web-based Food Frequency of Intake Survey (FFQ NEXT detailed version) provided by Kenpakusha Co Ltd (hereafter referred to as Kenpakusha) on its servers and asked to respond to the survey. If responses to the web-based FFQ cannot be confirmed by the day of the visit, participants may be asked to respond at the site on the day of the study. Research subjects who have participated in the study to the end will be sent an acknowledgement Amazon gift certificate worth 5,000 yen by email from the DLS (Business Unit) at a later date.

Other related information

Among the members of "MYCODE," a genetic testing service conducted by the DeNA Life Science, Inc., participants who have agreed to participate in a comprehensive study will be invited to participate in this study through web and e-mail notifications. After obtaining informed consent for this study, participants will be asked to complete a questionnaire at the time of application regarding items related to vegetable preferences, selection criteria for this study to measure skin carotenoid concentrations, and available study dates for participation. Participants will be measured for their skin carotenoid levels measured at the study site. In addition, participants will be notified in advance through e-mail of a web-based version of the food frequency questionnaire (FFQ) and asked to complete it. Statistical analysis will be conducted by KAGOME CO., LTD. A search for genes associated with skin carotenoid concentration, vegetable preference, and vegetable consumption will be conducted using characteristics information such as age and gender, questionnaire data at the time of application, skin carotenoid concentration data, FFQ data obtained in this study, and SNPs data already obtained in the MYCODE study.
