Plain-language summary
The specific aim of this observational study is to characterize changes in bone turnover makers (BTMs), bone mineral density (BMD), and bone microarchitecture in a cohort of nurses during their first year of night compared to day shift work. The hypothesis is that night shift nurses will have poorer bone health indices at one year compared to day shift nurses.

Inclusion Criteria
* Healthy, nonpregnant adults 20-50 years old who recently (≤6 months) graduated from nursing school and were hired by University of Colorado Hospital for their first nursing position
* For women to be eligible, they must be premenopausal, not breastfeeding, not pregnant with no plans to become pregnant during the year of observation and willing/able to maintain their current method of contraception use as detailed below.
* Willing and able to travel to/from CU-AMC for study measurements at baseline and quarterly for one full year
Exclusion Criteria
* Non-nursing school related shift work 1 year prior to study. (note: many nursing students work as an Advanced Care Partner (ACP) or as a Student Nurse Extern (SNE) and these positions will not be considered exclusionary).
* Current smokers at baseline (or within the previous year of study).
* Individuals who are concurrently participating in another research protocol that would influence their safe participation in this study. For example, participants involved in a study that requires blood draws or ingestion of experimental medication as this would increase the risk of participation in our study and/or compromise study results.
* Any clinically significant unstable medical or surgical condition within the last year (treated or untreated), including history of a clinically significant abnormality of the neurological system (including cognitive disorders or significant head injury) or any history of seizure…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
