What this trial studies
This study investigates how physical activity and motivational counseling can affect fertility and pregnancy outcomes among women trying to conceive. It aims to determine the relationship between physical activity levels and fecundability, spontaneous abortion rates, and other birth outcomes such as gestational diabetes and preeclampsia. The study will utilize activity trackers and motivational conversations to encourage women to maintain or increase their physical activity during the preconception period and early pregnancy. A web-based platform will be used for recruitment and data collection.
Why it matters
Potential benefit: If successful, this study could provide evidence that increased physical activity improves fertility and reduces pregnancy complications.
How similar studies have gone: Other studies have shown positive associations between physical activity and fertility outcomes, suggesting that this approach is promising.
