Who Can Join?

You can enroll if you are:

  • A nurse or nursing student
  • Age 19 and over, but born after January 1, 1965
  • Living in the United States or Canada
  • Currently working, not working, or retired
  • If you’re already participating in another study (including the Growing up Today Study/GUTS)—that’s okay! You can still participate in NHS3!

Nurses must have or be working towards one of the following certifications:

  • Registered Nurse (RN)
  • Licensed Practical Nurse (LPN)
  • Vocational Nurses (LPN/LVN)
  • Specialized RNs, such as Nurse Practitioners (NP), Nurse Anesthetists (CRNA) or other RNs holding advance practice certifications/licensures (e.g. Certified Nurse Midwife)
  • Nurses who have earned non-nursing health-related degrees (e.g. MD, DDS, PhD).

Do I need to be invited to participate?

No! You do not need a special invitation to join the Nurses’ Health Study 3. Anyone who is eligible can participate. We hope you will help us spread the word.

What’s the deadline for joining?

We will continue recruiting participants until we reach our goal of 100,000.

Who can’t enroll in this study?

  • Anyone younger than 19 (but check back when you turn 19 to see if enrollment is still open)
  • Anyone born before January 1, 1965 (but we need your help—please tell nurses who qualify about this opportunity)
  • People living outside the United States or Canada
  • Professionals in nursing-related fields who are not RNs or LPNs/LVNs, such as Certified Nursing Assistants (CNA), Patient Care Assistants (PCA), State Tested Nurse Aides (STNA), or Nursing Assistants-Registered (NA/R)
  • Allied-health professionals who are not nurses, such as Physician Assistants, Dietitians, Respiratory/Occupational/Physical Therapists, Speech Pathologists, etc.
  • Current participants of NHS1 or NHS2 (but please spread the word by telling your eligible nurse-friends!)

I have an unusual medical history. Do you still want me to participate?

Yes! We hope everyone who is eligible will join. Occasionally, participants who have already had a major illness may not be asked to complete later questionnaires. But joining and completing the first questionnaire is very important!

Why only nurses?

NHS follows participants throughout their lives. Registered nurses were selected for the original study because researchers anticipated that their nursing training would increase their ability to respond with a high degree of accuracy to brief, technically-worded questionnaires. Researchers also hoped that nurses’ commitment to health would help motivate them to participate in a long-term study. The study still focuses on nurses so the researchers can accurately identify trends over time.

I’m not eligible but I wish I could participate…

If you’re not eligible to enroll in the study, you can still play an important role by helping us spread the word!

OK, I’m eligible. What’s required?
