Sleep-wake cycle of adolescents in Côte d'Ivoire: influence of age, gender, religion and occupation.

abstract：:The evening chronotype is strongly associated with greater alcohol use, though mechanisms underlying this association are not well understood. The current study evaluated emotion regulation as a potential mechanism linking evening chronotype and alcohol use. Participants were 81 undergraduate students. Chronotype was ...
