Demographic characteristics, lifestyle habits, allergy history, and family history were investigated using a questionnaire. The changes in heart rate and blood pressure from supine to sitting were monitored using a sitting test. The possible differences between STS patients and healthy children were analyzed using univariate analysis. Logistic regression analysis was used to explore the independent risk factors for STS. Univariate analysis showed that the daily sleeping time of the STS children were significantly shorter than that of the control group [(8.8 \u00b1 1.2) hours\/day vs. (9.3 \u00b1 1.0) hours\/day, P = 0.009], and the proportion of positive family history of syncope in the STS patients was higher than the controls (4\/42 vs. 3\/181, P = 0.044). Multivariate logistic regression studies showed that reduced daily sleeping time was an independent risk factor of STS in children (P = 0.006). Furthermore, when daily sleeping time was prolonged by 1 h, the risk of STS was decreased by 37.3%.<\/jats:p>\n<\/jats:sec>\n<jats:sec
