Trial Outcomes & Findings for Evaluation of Diet and Sleep in Vascular Health: A Pilot Study (NCT NCT04990973)

NCT ID: NCT04990973

Last Updated: 2024-10-17

Results Overview

The 19 questions which compose this survey assess sleep quality, latency, duration, habitual sleep efficiency, sleep disturbances, medication use and daytime dysfunction. Scores range 0 (minimum) to 21 (maximum) with \>5 indicating poor sleep quality so a lower score is a better outcome.

Measure
Mediterranean Diet, Then Average American Diet
Healthy participants that are randomized to the MedDiet followed by a 4-week washout and a crossover to the AAD. Average American Diet (AAD): Participants will follow specified diet requirements. Macronutrient targets for the AAD will be approximately 35-37% of energy from fat (13.5% from saturated fat), 15% from protein, and 48-50% from carbohydrates (10 g fiber/d for an average 2000 kcal/d diet). Mediterranean Diet: Participants will follow specified diet requirements. Macronutrient targets for the Mediterranean diet will be approximately 40% of energy from fat (8.5% from saturated fat), 20% of energy from protein, and 40% from carbohydrates (40 g fiber/d for an average 2000 kcal/d diet).

PRIMARY outcome

Timeframe: 4 weeks

Population: 1 participant in the Mediterranean Diet condition did not complete the questionnaire.

The 19 questions which compose this survey assess sleep quality, latency, duration, habitual sleep efficiency, sleep disturbances, medication use and daytime dysfunction. Scores range 0 (minimum) to 21 (maximum) with \>5 indicating poor sleep quality so a lower score is a better outcome.

PRIMARY outcome

Timeframe: 4 weeks

Sleep Fragmentation is an index of restlessness during the sleep period expressed as a percentage (0 to 100%). The higher the index, the more sleep is disrupted.

Timeframe: Change from baseline to 4 weeks

Population: Due to study termination, data was not collected and therefore not analyzed.

Urinary 6-sulfatoxymelatonin will be measured by competitive ELISA and urine creatinine by clinical chemistry analyzer.
