Objectives:
Attrition and nonadherence are common concerns that can distort findings in clinical trials. This study examines the potential for systematic attrition in the largest sample to date of adolescents undergoing sleep manipulation.
Methods:
Using pooled data across two trials involving 242 adolescents, a cumulative logistic regression tested whether demographics and baseline sleep predicted study completion/adherence.
Results:
Race, a composite measure of socioeconomic status, and its elements (e.g., income, education) individually predicted completion/adherence. When entered concurrently into a multivariate predictive model, only socioeconomic status and study (trial A vs. B) were significant. Adolescents from households with higher socioeconomic status were more likely to complete or adhere to the protocol than those from households with lower socioeconomic status, p < .001.
Conclusions:
Systematic attrition in sleep manipulation research could distort conclusions about under-resourced groups. Future sleep trials should intentionally measure systemic/structural factors and adopt strategies to recruit and retain participants from various backgrounds.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
