Pistacho and Sleep Quality (PistaSleep)

2026年6月10日 更新者：Rocio Campos-Vega、Universidad Autonoma de Queretaro

Effect of Pistachio (Pistacia Vera L.) Consumption on Locomotor Activity and Molecular Regulation of the Circadian Clock in Adipose Tissue of Overweight Adults

The goal of this study is to evaluate the effect of pistachio (Pistacia vera L.) consumption on plasma melatonin, antioxidant capacity, and circadian rhythms in overweight young adults.

The main question it aims to answer are:

  • Can the consumption of pistachios, specifically their content of compounds like phyto-melatonin, effectively regulate the human biological clock and circadian rhythms?

主要结果指标

结果测量
措施说明
大体时间
Body composition analysis
大体时间：Baseline, 2 weeks, 4 weeks
Body composition analysis (BCA, including fat mass [FM] and fat-free mass [FFM], in kg and %) was performed with a seca mBCA 514/515 medical Body Composition Analyzer (Allers Hamburg, Germany). The measurements were conducted in accordance with the guidelines of the International Society for the Advancement of Kinanthropometry (ISAK).
Baseline, 2 weeks, 4 weeks
Waist circumference
大体时间：Baseline, 2 weeks, 4 weeks
Waist circumference (WC, in cm) was measured using an ergonomic SECA 201 measuring tape.
Baseline, 2 weeks, 4 weeks
Plasma melatonin
大体时间：Baseline, 2 weeks, 4 weeks
Plasma obtained from the same samples of biochemicals determinations. Plasma melatonin levels were measured before and after the intervention using a commercial plasma melatonin kit.
Baseline, 2 weeks, 4 weeks
Circadian locomotor activity
大体时间：Through study completion during 28-days.
A temperature sensor on the wirst, an activity and body position sensor was placed on the participant's arm and a luxometer was worn on the neck with a pendant over the clothing.
Through study completion during 28-days.
Questionnaire of activity during the day
大体时间：Baseline, 2 weeks, 4 weeks
Horne and Östberg morning- evening test. Visual Analog Score with a cumulative score scale
Baseline, 2 weeks, 4 weeks
Physical activity questionnaire (IPAQ)
