High vigor-activity scores reflect a good mood or emotion, and low scores in the other subscales reflect a good mood or emotion.
Total mood disturbance, which is calculated by subtracting the vigor subscale score from the total subscale score (range 0-200), also will be assessed.

Physical activity
Časové okno: 11-16 years post CALERIE trial
|
Physical activity as measured by the 7-Day Stanford Physical Activity Recall (PAR).
The PAR estimates an individual's time spent in sleep and physical activity for the 7 days prior to the interview.
Energy expenditure based on time spent in sleep and physical activities can be estimated.
Sub-scores of energy expenditure for each of the following activities are calculated, summed, and averaged to estimate energy expenditure as kilocalories per day: sleep, moderate physical activity, hard physical activity, and very hard physical activity.
Higher scores indicate greater physical activity per day.
Metabolic equivalent (MET) value for each activity is provided: 1 MET for sleep, 4 METs for moderate activity, 6 METs for hard activity, and 10 METs for very hard activity.
Time spent in each activity over 7 days is multiplied by the appropriate MET value.
The minimum value for each activity is zero; there is no maximum value.

Plán pro data jednotlivých účastníků (IPD)
Plánujete sdílet data jednotlivých účastníků (IPD)?
Popis plánu IPD
Podle zásad NIH Data Public Access Policy po uzavření studie datové koordinační centrum na Duke University uzamkne elektronickou databázi a vyčistí a deidentifikuje data před zveřejněním. Biovzorky odebrané pro bankovnictví budou deidentifikovány a převedeny do NIA AgingResearchBiobank, která využívá nejmodernější inventární systém pro skladování a distribuci studijních vzorků pro budoucí vědecký výzkum.
K dispozici bude také protokol studie a formulář informovaného souhlasu.
Časový rámec sdílení IPD
Kritéria přístupu pro sdílení IPD
Povolení používat data nebude omezeno. Zainteresovaní vyšetřovatelé se však musí zaregistrovat na příslušné webové stránce, aby měli přístup k údajům, které budou zpřístupněny prostřednictvím stažení. Data shromážděná v této studii budou vhodná pro regresi přizpůsobenou longitudinálním datům a multivariační multivariabilní analýze nebo dobré shody chí-kvadrát, neparametrické míry asociace.
Vyšetřovatelé, kteří mají zájem o přístup k biologickým vzorkům, budou muset požádat o přístup předložením žádosti prostřednictvím webové stránky NIA AgingResearchBiobank (https://agingresearchbiobank.nia.nih.gov/how-to-make-a-request/). K podání této žádosti se bude muset určený člen vyšetřovacího týmu zaregistrovat jako uživatel na webu AgingResearchBiobank. Každý výzkumník může podat žádost o přístup k biovzorkům pro budoucí výzkum, ale pro získání přístupu musí být schválen AgingResearchBiobank. Biovzorky budou poskytnuty jako vzorky, které budou odeslány schváleným vyšetřovatelům.
