Brief Summary

The COVID-19 pandemic and social isolation order induced stress/anxiety as well as cellphone dependence. As a result, sleep disruption and mental distress became major health concerns. Gamma-aminobutyric acid type-A receptor (GABAAR) is one of the key players in modulating sleep. Dihydromyricetin (DHM), an herbal compound, plays a role in GABAAR modulation and mitigating anxiety. The investigators' partner in China obtained 288 participants who completed the online survey to gain insight into how stress/anxiety and time spent on cellphones affected sleep and mood. The participants were then enrolled in a randomized placebo-controlled double-blind study to assess the effects of DHM on sleep and improvement on stress/anxiety and cellphone using time.

Outcome Measures

Primary Outcomes (4)

  • Effect of DHM on sleep duration

    Changes in hours of sleep reported as the difference between self-reported hours of sleep before and after DHM or placebo.

    20 days

  • Effect of DHM on stress levels

    Changes in stress levels reported as the difference between self-reported stress levels before and after DHM or placebo. Stress levels were scaled from 0 to 10, with 10 being the highest stress level.

    20 days

  • Effect of DHM on cellphone time

    Changes in hours spent on cellphone reported as the difference between self-reported cellphone usage before and after DHM or placebo.

    20 days

  • Effect of DHM on feelings after waking up

    Changes in negative feelings after waking up, reported as the difference between the self-reported negative feelings before and after DHM or placebo. In the survey, "feelings after waking up" included negative feelings such as tense, lack of motivation, and irritable/angry. To quantify these feelings, a 'Yes' counted as -1 point, a 'No' counted as 0 points, and a 'Not sure' counted as -0.5 points. The sum of these scores were calculated as the total negative feeling after waking up. Lower score (more negative) indicated worse feelings.

    20 days

Study Arms (2)

DHM group

EXPERIMENTAL

This arm is to evaluate DHM effects on the intervention of stress-induced insomnia during the pandemic. DHM granular preparation contains DHM 200 mg plus same excipients as placebo. The 244 participants were taken DHM granular preparation, which was dissolved in \~100 ml water for oral administration, once daily for 20 days.

Dietary Supplement: DHM

Control group

PLACEBO COMPARATOR

The placebo contained excipients including extracts of celery, strawberry, oranges, rose, and beet blended in powder form of 1 g

Dietary Supplement: Placebo

Interventions

DHMDIETARY_SUPPLEMENT

DHM is a positive modulator of GABA. We hypothesize the DHM could reduce stress/anxiety induced insomnia during the pandemic

Model Details: 288 subjects were recruited for the study. The sample size was based on a prior power analyses using G-Power 3, for a Mixed Model Repeated Measures Analysis of Variance (MMRMA) design, assuming a statistical power of 0.8, moderate effects of the DHM effects on sleep outcomes, and hypothesis tests conducted at a probability value of .05.
