This thesis consists of two studies. The first study aimed to evaluate the impact of a multi-component intervention involving teacher training, changes in the school environment and physical education classes on sleep duration, sleepiness and nutritional status of elementary school adolescents. The second study investigated the impact of the same intervention on sleep quality, eating disorders and symptoms of depression in a subgroup of obese adolescents. Sampling was performed by clusters. Adolescents from 7th to 9th grade from the six public schools of full-time education in Fortaleza, Brazil, were included, and three schools were randomly allocated to each condition (intervention or control). The intervention lasted four months. Data collection was performed at the beginning, in July 2014, and immediately after the intervention, in December 2014. In the first study, sleep duration was obtained by self-report (short duration <8h); the degree of daytime sleepiness by the Epwort Sleepiness Scale and nutritional status by the body mass index. In the second study, in obese adolescents, subjective sleep quality was measured by the Pittsburgh Sleep Quality Index; symptoms of depression by the Depression Population Screening Scale; eating disorders, by the Eating Attitudes Test- 26. The total sample consisted of 1085 students (548 in the intervention group and 537 in the control group), aged 11 to 18 years. Significant impact of the intervention was observed in the frequency of adolescents with satisfactory sleep duration on school days, for the age group of 11 to 12 years and also in those who attended the 7th grade. Significant effects in overweight individuals were identified only in the lower social strata. In obese adolescents, the intervention promoted a significant increase in sleep hours and a decrease in the percentage of adolescents with symptoms of depression. In conclusion, multi-component intervention with the mentioned characteristics may have a beneficial effect on sleep duration and nutritional status of adolescents, particularly in the earliest age groups and promote improved sleep duration and symptoms of depression in obese adolescents. These results are relevant in targeting health interventions for the school population.
