| - | Scalp hair samples were collected from ~59,000 adult [[start|Lifelines]] participants during [[2A Visit 2]]. The main aim of hair collection was to use the samples for the assessment of hormone levels, e.g. [[https://en.wikipedia.org/wiki/Cortisol|cortisol]] ([[sections|section]]: [[physical state]]).\\ | + | [[start|Lifelines]] participants were asked the following questions about the state of their hair ([[sections|section]]: [[physical state]]).\\ |
| - | The hair collection protocol was piloted in a subcohort of 300 participants in september 2013 (during [[1A Visit 2]]) as an [[additional assessments|additional assessment]] initiated by researchers at the [[https://www6.erasmusmc.nl/roar/departments/internal-medicine|Department of Internal Medicine]] of Erasmus University, the Netherlands. During [[2A visit 2]] it was extended to ~59.000 participants. ~6000 samples have been analyzed for cortisol and cortisone and this data can be requested by sending an e-mail to data@lifelines.nl. | + | These questions can be combined with the analyses of the available [[hair samples]] from Lifelines participants. |

| - | Cortisol levels are typically assessed in serum, saliva, or urine samples. However, due to the circadian rhythm of cortisol, its pulsatile secretion, and the daily variation due to changing circumstances like acute stress, these samples provide non-representative snapshots of chronic cortisol levels in the human body. | + | | what is your natural hair colour at the moment? | wat is op dit moment uw natuurlijke haarkleur? | hair_colour_adu_q_1 | hair1 | [[2A Questionnaire 2|2A]] | 18+ | |
| - | For that reason, a novel non-invasive parameter to measure cortisol using scalp hair was developed((Manenschijn L et al. (2011). Evaluation of a method to measure long term cortisol levels. Steroids 76(10-11):1032-1036)), providing the unique opportunity to measure long-term cortisol levels that reflect the mean levels of several months (since hair grows with an average of 1 cm per month). Using this technique, it is now possible to study chronic cortisol levels over time in very large cohorts((Russell E. et al (2015). Toward standardization of hair cortisol measurement: results of the first international interlaboratory round robin. Therapeutic Drug Monitoring 37(1):71-75)). | + | | how often do you wash your hair a week? | hoe vaak wast u uw haren per week? | hair_wash_adu_q_1 | hair2 | [[2A Questionnaire 2|2A]] | 18+ | |

| - | During [[2A visit 2]], participants were asked to provide a lock of hair. Nurse practitioners that assisted in the visit cut off a lock of hair close to the scalp using clean scissors. The lock of hair was placed in an envelope, clearly marked and registered, and stored at room temperature.\\ | + | | have you used some form of corticosteroids (eg prednisone tablets, nasal spray, puffs, infusion, injection or skin creams) in the past three months? | hebt u in de afgelopen 3 maanden een vorm van corticosteroïden (bv prednisontabletten, neusspray, longpufjes, infuus, injectie of huidcremès) gebruikt? | hair_cortcosteroids_adu_q_1 | hair4 | [[2A Questionnaire 2|2A]] | 18+ | |
