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 Stress and Time to Pregnancy—a new 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. Couples who are planning to become pregnant in the near future or have recently begun trying without the use of fertility treatments are eligible to enroll.

Male and female participants will complete initial 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. Free pregnancy test strips are provided.

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

At home, female participants 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 the couple conceives or seeks medical intervention.
