Trial Outcomes & Findings for Aromatase Inhibitors and Weight Loss in Severely Obese Hypogonadal Male Veterans (Pilot) (NCT NCT02959853)

NCT ID: NCT02959853

Last Updated: 2020-01-30

Results Overview

Muscle strength was assessed using Biodex System 4 Isokinetic Dynamometer (Shirley, NY). Peak torque for isokinetic knee extension and flexion was measured at baseline, 6 months on the right leg. During the testing, participants sat with their hips flexed at 120 degrees, secured with thigh and pelvic straps. Testing was performed at an angular velocity of 60 degrees per second. The best result of 3 maximal voluntary efforts for each knee flexion and extension was used as the measure of absolute strength and reported as peak torque at 60 degrees in Newton-meter (N\*m) units. The higher the measured Newton-meter (N\*m), the greater the measured muscle strength.

PRIMARY outcome

Timeframe: baseline, 3 and 6 months

Symptoms of androgen deficiency were measured with 3 validated questionnaires done at baseline, 3 and 6 months. 1. The Quantitative Androgen Deficiency in the Aging Male (qADAM) questionnaire uses questions from a scale of 1-5. The final summation yields a total score between 10 (most symptomatic) and 50 (least symptomatic). 2. The second questionnaire used was the International Index of Erectile Function (IIEF). Total score ranges from 5 to 25, with 5 being severe erectile dysfunction and 25 being no erectile dysfunction. 3. The third questionnaire used was the Impact of Weight on Quality of Life Questionnaire-Lite (IWQOL-lite). Total score ranges from 31 to 155, with 31 being least symptomatic and 155 being the most symptomatic. Score change at 3 months calculated by: total score at 3 months minus total score at baseline Score change at 6 months calculated by: total score at 6 months minus total score at baseline
