Obesity and Cardiovascular Diseases, Cross-sectional Study in Saudi Arabia (OCCURS)

December 22, 2025 updated by: Novo Nordisk A/S

The purpose of this research study is to collect information on participants body weight, blood sugar levels, heart related diseases and lifestyle. The collected information will help estimate the prevalence of participants disease.

This study will take about 6 months. However, participants involvement in the study will not extend beyond their routine visit and will thus require a maximum of 1 day.

If participants choose to take part, they will be asked to give information about their health in routine clinical visit. Participants will be asked to complete a questionnaire about their lifestyle. Participants will complete this questionnaire during their normally scheduled visit with their doctor. Participants will continue their normal way of life and will not get any medication other than those prescribed to them by their doctor.

Participants will have no direct benefit from participation in this study and there are no risks involved.

Participants decide voluntarily whether they want to participate in this study or not. Participants' decision will not affect their medical care and they do not have to justify their decision.

Participants are free to leave the study at any time and without giving reasons. This does not affect their current or future treatment. The data collected up to that point are still being evaluated.

There is no additional cost to participants for being in this study.
