PRESTO (Pregnancy Study Online)

PRESTO is a web-based research study that examines whether lifestyle factors such as diet, exercise, and medication use have an impact on fertility and pregnancy.

Women are being invited to complete one online questionnaire at enrollment and every 2 months for 12 months, or until conception, whichever occurs first.

Women will also have the opportunity to invite their male partners to participate.

Half of enrolled women get a VIP membership at, an “app” that records menstrual patterns and fertility signs (available to new FF members only).

PRESTO is a non-profit study being conducted at Boston University. It is funded by the National Institutes of Health.

Eligible female participants are:

-Age 21-45

-Not currently using any methods to prevent pregnancy

-Not using fertility treatments

-In a stable relationship with a male partner

-Thinking about becoming pregnant in the next 6 months and not currently pregnant

-Willing to participate in a 12-month study

The study objectives are to identify lifestyle factors that affect the chances of successful pregnancy. The study will also examine predictors of miscarriage, preterm birth, and low birth weight.

– One online survey at enrollment (30-35 minutes).

– One online survey every 2 months for up to 12 months or until you get pregnant (10-15 minutes).

– One online diet survey 10 days after enrollment (30-40 minutes).

– If you become pregnant, one survey in early pregnancy (10-15 minutes), one survey in late pregnancy (10-15 minutes), and one survey at 6 months’ postpartum (10-15 minutes).

– Optional: male partner survey (10-15 minutes) and male dietary survey (30-40 minutes).
