Environmental Pediatrics Research Studies NYU FIRST Study


If you are thinking about becoming pregnant in the next 6 to 12 months, you may be eligible to participate in NYU FIRST—short for Factors Influencing Reproductive Success and Time to Pregnancy—a study led by researchers in the Division of Environmental Pediatrics at NYU Langone.

VIDEO: Dr. Linda Kahn discusses the NYU FIRST Study, which investigates how lifestyle factors may affect fertility.

NYU FIRST is an observational study investigating the role of diet, lifestyle, and chemical exposures on fertility. Women who are planning to become pregnant in the near future or have recently begun trying, either naturally or with the use of fertility treatments, are eligible to enroll.

Eligible participants will complete background and dietary questionnaires and attend a baseline clinic visit in which they will provide blood, urine, and other biological samples; be weighed and measured; and undergo cardiac function tests and body composition analysis.

In monthly follow-up emails or telephone calls, depending on the participant’s preference, participants will report on their pregnancy status and any changes in behavior. Free pregnancy test strips will be provided.

At home, participants will collect a first-morning urine sample once a week and mail it to our lab for analysis. In-person visits are scheduled once every five months until conception.
