The Sleep Experiment: Primary and Secondary Outcomes

The individual experiments in the Lifestyle Experiment (Sugar, Fitness, Sleep and Food) will all have shorter term, more responsive metrics called primary outcomes. Those are outcomes that are likely to change over the short (usually 3 month) period of the individual experiment. We call these "responsive" metrics because we expect that they might respond in that short period whereas other metrics, although very important to the overall experiment, they take longer to respond. Some of these longer term metrics might change in this short period but they might not. Thus, these longer term metrics will be secondary outcomes for the individual experiments.

The Primary Outcomes for the Sleep Experiment are as follows:

• Sleep Score: (Various Devices)

  • Total Sleep

  • Timing of Sleep

  • Restlessness Measures

  • Amount of Deep Sleep

  • Amount of REM Sleep
    

• Epworth Sleepiness Scale

• Subjective Motivation Scale

The Secondary Outcomes for the Sleep Experiment are as follows:

• HbA1c

• Fasting Insulin

• Fasting Glucose

• Triglycerides

• hsCRP
