Senior Theses

Despite the topic’s popularity in research, the relationship between sleep duration and physical activity (PA) remains unclear. Measurement protocol differences, highly specific samples, and incomplete data contribute to varying results suggesting that additional research is needed. The purpose of the TRACK II study was to examine the relationship between PA, BMI, and self-reported sleep in adolescents. 369 9 th and 10 th grade students from 2 diverse school districts participated in the study.

Relationships Of Chronotype, Social Jetlag, Sleep, Physical Activity And Diet With Mood, Perceived Stress, Obesity, Blood Pressure And Prostate Cancer, Daria M. Mcmahon

Theses and Dissertations

Background: Chronotype, social jetlag, poor sleep, proinflammatory diet, and low physical activity have been associated with increased risk of chronic diseases: obesity, diabetes, cardiovascular disease, depression and cancer. Yet the relationships between these factors have not been extensively investigated in prospective studies.

Methods: Two studies were conducted. The first study followed 390 healthy men and women ages 21-35 for two years. Social jetlag [SJL] and sleep measures (total sleep time [TST], sleep onset latency [SOL], wake after sleep onset [WASO]), sleep efficiency [SE]), were derived from physical activity personal (armband) monitoring. The participants wore the armband for 4-10 …
