A system for determining whether sleep disorders suffered based on forecast result and a method thereof are provided. By forecasting a occurrence timeframe of sleep disorders and a disorder physiology data on the occurrence timeframe in accordance with a measured physiology data by a sleep disorders forecast model, and determining a subject were suffered sleep disorders when a part of the disorder physiology data in the measured physiology data on the occurrence timeframe, the system and the method can determine whether a subject were suffered sleep disorders quickly, and can achieve the effect of determining what the sleep disorder suffered by the subject is.一種依據預測結果判斷是否存在睡眠障礙之系統及其方法,其透過睡眠障礙預測模型依據受測生理資料預測睡眠障礙發生之時間區間及睡眠障礙發生時所測得之障礙生理資料,當受測生理資料於時間區間內存在符合障礙生理資料之片段資料後,判斷受測者患有睡眠障礙之技術手段,快速判斷受測者是否患有睡眠障礙,並達成自動判斷受測者患有之睡眠障礙的技術功效。步驟310 提供可預測睡眠障礙之睡眠障礙預測模型步驟330 讀取受測者於睡眠時所測得之受測生理資料步驟350 睡眠障礙預測模型依據受測生理資料預測睡眠障礙發生之時間區間及睡眠障礙發生時所測得之障礙生理資料步驟370 判斷受測生理資料於時間區間內是否存在片段資料符合障礙生理資料步驟390 確認受測者患有睡眠障礙
