What this trial studies

The PROMISE study aims to explore the impact of pre-conception lifestyle factors such as sleep, nutrition, and physical activity on reproductive outcomes for women and their children. By focusing on women aged 18-44 who are seeking pregnancy, the study seeks to gather data on social and epidemiologic determinants of health before conception. This observational study will utilize validated surveys to collect information on modifiable lifestyle factors, with the goal of identifying actionable interventions that could improve long-term health outcomes. The study will follow participants for up to 25 years, allowing for a comprehensive analysis of health trends over time.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18-44 who are actively seeking pregnancy and have not undergone prior IVF cycles.

Not a fit: Patients using donor oocytes or gestational carriers, or those unable to provide informed consent, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved reproductive health outcomes for women and their children by identifying effective pre-conception interventions.

How similar studies have performed: While there is existing research on maternal and child health, this study's focus on pre-conception factors is relatively novel and has not been extensively tested.
