Effect of Estrogen Therapy on Objective Sleep Quality in Postmenopausal Women

December 26, 2012 updated by: Pimpika Tansupswatdikul, MD., Chulalongkorn University

Effect of Estrogen Therapy on Objective Sleep Quality in Postmenopausal Women at Menopause Clinic, King Chulalongkorn Memorial Hospital, Double- Blind, Randomized, Placebo-controlled Trial

  1. Sex hormone including estrogen have synergistic effect to serotonin activity and decrease activity of monoamine oxidase activity so the norepinephrine is not be metabolized, these substance are important to regulate hemostasis and circadian process of sleep

  2. Estrogen also regulate gamma-aminobutyric acid (GABA) secretion

    • GABA substance is in order to initiate sleep and continue sleep
  3. According to epidemiologic data, problem of sleep was increasing in postmenopause group compare to premenopause group (aged-match)
  4. This research perform to find out the actual effect of estrogen in improving sleep quality.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  1. 40-60 year-old postmenopausal women with insomnia and mild-moderate vasomotor symptom were screened and included in project

  2. Block of four randomization was use to categorize participants into 2 groups

    • Study group (estrogen patch)
    • Control group (placebo patch)

  3. Sleep quality was measured before intervention by subjective and objective sleep quality

    • Subjective sleep quality (self sleep questionnaire)
    • Objective sleep quality (wrist actigraphy and sleep diary):

    wrist actigraph sleep test at home for 1 week

  4. Intervention phase : continuous use of weekly patch for 8 weeks

    • Estrogen patch in study group
    • Placebo patch in control group

  5. Follow up phase

    • At 4 weeks of use, investigator will telephone call for follow up the participant's compliance and the side effects during patch use.
    • After completed use of 7th patch, sleep quality was measured again, self sleep quality questionnaire and 1 week-wrist actigraphy and sleep diary test
  6. Then the data will be analysed and open label, in nonhysterectomized postmenopausal women in study group will take the medroxyprogesterone acetate for washing out the endometrium for 2 weeks
  7. The participants will be counseled, further investigate and proper treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sleep efficiency (SE)
Time Frame: 8 months
Sleep efficiency is proportion of sleep in the period potentially filled by sleep-ratio of total sleep time to time in bed.
8 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Sleep latency (SL)
Time Frame: 8 months
Sleep latency is the time period measured from "lights out," or bedtime, to the beginning of sleep.
8 months
Total sleep time (TST)
Time Frame: 8 months
TST is amount of actual sleep time in a sleep period.
8 months
Wake time after sleep onset (WASO)
Time Frame: 8 months
WASO is the total time of awake occurring between sleep onset and final wake up.
8 months
Number of awakening
Time Frame: 8 months
Number of awakening is the number of awakening during onset of sleep and final wake-up.
8 months
Score of two sleep quality assessment questionnaires.
Time Frame: 8 months
  • Insomnia severity index is the 7 topic questionnaire for determine the severity of insomnia problem.
  • Ebworth severity index is the questionnaire to assess daytime sleepiness.
8 months
