30-50 subjects aged from 20 to 80 years old without sleep apnea or with low arousal threshold obstructive sleep apnea will be enrolled in this randomized, double-blind, cross-over, and placebo-controlled 8-week period experiment.
At the treatment period (0th to 8th week of the experiment), subjects will receive 2 placebo or capsules of sesame complex (37-56mg sesamin per capsule). The 9th to 11th week will be the washout period. The control and sesamin group will be cross-over at 11th week to 12th week of the experiment. Sleep quality, life quality examination and anti-oxidative functions will be carried out in this study. The basic anthropometric examination will be carried out at the beginning, 4th, 8th, 11th, 15th, and 19th week of the study. Routine laboratory parameters including liver function, kidney function, blood sugar, lipid profile, and anti-oxidative status will be investigated at the beginning, 8th, 11th and 19th week of the study. The questionnaire evaluation including the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Beck Depression Inventory-II, Beck Anxiety Inventory, and Short form-12 items health survey will be investigated at the beginning, 8th, 11th, and 19th week of the study. We expect that sesame complex including 37-56mg sesamin may improve oxidative status which in turn ameliorates the sleep quality, life quality, and anti-oxidative functions in patients with sleep disorder.
