Trial Outcomes & Findings for Omega-3 for Peri- and Postmenopausal Depression (NCT NCT00825994)

NCT ID: NCT00825994

Last Updated: 2014-08-21

Results Overview

The instrument used to measure mood at each visit was the Montgomery-Åsberg Depression Rating Scale (MADRS). The MADRS is a widely used 10-item clinician-rated scale that describes the severity of depressive symptoms (range 0-60, higher score indicates greater symptom burden).

Participant Flow

Of the 31 participants who consented at V1, 7 were ineligible at this visit. The remaining 24 were given a 1-week single-blind placebo lead-in. Women who met criteria for placebo response, defined as a \>= 50% decrease in MADRS (Montgomery-Asberg Depression Rating Scale) from screening to end of the run-in phase, were excluded from the study.

PRIMARY outcome

Timeframe: 8 weeks

Population: Of 31 women who consented to participate per protocol 24 were eligible. Of these 24 eligible participants, three women withdrew and one was a placebo responder. 20 women started omega-3 fatty acid treatment and 19 completed the study.

The instrument used to measure mood at each visit was the Montgomery-Åsberg Depression Rating Scale (MADRS). The MADRS is a widely used 10-item clinician-rated scale that describes the severity of depressive symptoms (range 0-60, higher score indicates greater symptom burden).

SECONDARY outcome

Timeframe: 8 weeks

Population: Of 31 women who consented to participate per protocol 24 were eligible. Of these 24 eligible participants, three women withdrew and one was a placebo responder. 20 women started omega-3 fatty acid treatment and 19 completed the study. Of these 20, 15 women had hot flashes at baseline and could be included in the hot flash analysis.

Vasomotor symptoms (hot flashes) were tracked by using a self-report Hot Flash Related Daily Interference Scale (HFRDIS). The HFRDIS is a 10-item self-report questionnaire in which subjects rate the degree to which hot flashes interfere with daily activities and quality-of-life during the prior week. Each item is rated on a scale from 0 (does not interfere) to 10 (completely interferes) for a total score range of 0-100 (higher score indicates greater symptom burden/interference).
