... l, military, and moral-ethical. Participants: Survey data were obtained from all members of the Class of 2007 (N~1300), who ranged in age from 17 to 22 years. A stratified sample (n = 80) was selected to wear wrist-activity monitors. An additional 40 members of the junior and senior classes participated in the summer portion of the study. Measurements and Results: Sleep patterns prior to entering the United States Military Academy were compared with patterns during cadet basic training and fall and spring semesters. Actigraphy data were recorded on a sample of the class (n = 80) for 50 days during cadet basic training and 30 days during fall and spring semesters. During cadet basic training, incoming cadets received 5 hours 40 minutes of sleep per night. During fall 2003 semester, these same cadets received 4 hours 50 minutes of sleep on school nights and 6 hours 32 minutes on weekends. Sleep received during spring 2004 semester was similar, with 5 hours 06 minutes on school nights and 6 hours 29 minutes on weekends. Conclusions: This first year of baseline data collection describes cadet sleep patterns and sets the stage to assess the effectiveness of follow-on interventions. Citation: Miller NL; Shattuck LG.
