Social jet lag

2 papers6 findings

C, W, M, H: cells, worms or flies, mice, humans. Dark: independent labs found the same change there. Light: one lab or one study. Outline: nothing yet.

Labs are independent when their papers share no last author and no institution.

Against: findings that point the other way from most findings on the same outcome.

On aging: the drug’s trials ARN judged to be about aging, of every trial that tests it for any use.

No results posted: trials that ended more than a year ago with no results on ClinicalTrials.gov and no paper in ARN’s record.

Company ties: findings with an author at a company, or from a paper whose competing-interests statement declares ties to one.

Body mass index

no changein humans1

1 study

Social jet lag has no effect on body mass index in humans (p =.36).
“Social jet lag was not significantly associated with body mass index (p =.36), number of chronic conditions (p =.59), or self-rated memory (p =.72).”

Associations

Depressive symptoms

upin humans2

2 studies

Social jet lag is associated with depressive symptoms in humans.
“higher levels of social jet lag remained positively associated with higher depressive symptoms, and this association was moderated by age.”

Social jet lag is associated with depressive symptoms in humans (β = 0.14, p <.001, R-squared =.10).
“greater social jet lag was associated with higher depressive symptoms (β = 0.14, p <.001, R-squared =.10)”
