Sleep arrangement, marked with ethnic, economic status, and socio-cultural background characteristics, was more prevalent in non-western countries. The implication of sleep arrangement on psychosocial and physical development has not been definitively determined. Another study in Chinese adolescents revealed that adolescents and their parents had correlations in sleep/wake patterns, perceived sleep need, and insomnia symptoms [38]. All these studies revealed a close linkage in sleep behaviors between adolescents and their parents, though the intrinsic underlying mechanisms have not been clearly interpreted.
