Sažetak
In Croatia both elementary and high school students attend classes in two shifts. They generally go to school one week from 08:00 to 13:00 and the next from 14:00 to 19:00. Therefore, if the parents are working shifts too, all members of the family are "shiftworkers". In this study we compared the sleep characteristics of three groups of adolescents that attended school in two-shift system: first group with both parents working only day shifts, second group with one parent on day shift and the other one working evening, night or rotating shifts and third group with both parents working evening, night or rotating shifts. Our hypothesis was that the adolescents whose parents were working shifts would have more irregular sleep patterns and would consequently be more sleep deprived than the adolescents whose both parents were day workers. During October and November 2001 and 2002 a total of 2365 students from 24 elementary and high schools in Zagreb completed the Croatian version of School Sleep Habits Survey (1). In this study the results of 1141 students (nelementary= 656, nhigh= 485) of both genders, who lived with both parents and whose both parents were employed full-time, were analyzed. The average age of elementary school students was 12.2 years (S.D.=1.2) and of high school students 16 years (S.D.=1.2). Elementary and high school adolescents, whose both parents work shifts, go to bed significantly later on the morning shift week than the adolescents whose both parents work only day shifts or only one parent works unusual hours. For the other sleep variables the parents’ working time had more impact on sleep patterns of high school students than of elementary school students. High school students, whose both parents work shifts, wake up earlier in the morning shift week than the other two groups. Since they also go to bed later their total sleep time on morning shift is the shortest of all three groups. On weekends high school adolescents whose both parents work shifts go to bed later. They also show greater irregularity in their sleep patterns than adolescents whose both parents work dayshift or only one of them works unusual hours. The differences between their bedtime on weekends and both school weeks are greater than in other groups. The parental control over the adolescents’ bedtime is weakest on weekends and strongest on the morning shift week. However, that control is generally rare. Thus on the morning shift week only 11.2% of elementary school and 3.6% high school adolescents report their bedtime has been set by the parents. Biological factors aside, as adolescents get older their sleep habits are shaped by various psychosocial influences. The results of this study imply irregular sleep and wake time of parents to be a behavioral model related to adolescents sleep patterns. 1. Wolfson AR, Carskadon MA.
