目的：本研究旨在瞭解學齡前嬰幼兒睡眠時數、睡眠習慣與睡眠品質情形，並探討睡眠品質的相關因素及其對睡眠習慣之關係。方法：研究工具以自編的結構式問卷進行調查，針對新北市43家公共托嬰中心的嬰幼兒為研究樣本，問卷調查經家長同意後並代替填寫，總計有效問卷為1878份，資料分析包括描述性統計、卡方檢定和羅吉斯迴歸分析。結果：在1878位學齡前嬰幼兒中，男童981人（52.2%）、女童897人（47.8%），本研究1-3歲嬰幼兒的睡眠品質得分平均為3.03±0.41分。嬰幼兒的睡眠潛伏期、健康狀況、主要照顧者性別、教育程度、經濟狀況、同床共眠、陪伴一同入睡及睡眠環境等是嬰幼兒睡眠不良的相關因素。嬰幼兒睡眠潛伏期較長或時間不定者，其睡眠品質不良的可能性較高 （勝算比＝2.83，95%信賴區間＝2.15-3.72）。結論：新北市1-3歲公共托嬰中心嬰幼兒睡眠潛伏期、睡眠環境、主要照顧者社經地位與睡眠品質有關。

Objectives: This study aims to understand sleep hours, sleep habits and sleep quality of young children, and to explore the association between sleep quality and sleep habits factors in municipal infant care centers of New Taipei city. Methods: We used general investigation and self-made structured questionnaires to survey municipal infant care centers of young children who aged 1-3 years among 43 centers in New Taipei City. Information of questionnaires included socioeconomic characteristics, sleep hour, sleep habits and sleep quality in municipal infant care centers of young children. We used descriptive statistical analysis, chi-square test and multivariate logistic regressions to calculated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of poor sleep quality associated with sleep habits and socioeconomic related factors Results: Among 1878 pre-school infants and young children, 981 (52.2%) boys and 897 girls (47.8%) had an average sleep quality score of 3.03 ± 0.41 for infants and young children aged 1-3 years in New Taipei City. The sleep onset latency of young children, health status, gender and education level of primary caregiver, economic status, care giver accompanied sleep, bed-sharing sleep and the sleeping environment are all related factors of poor sleep quality in young children. Young children who seldom adjust their sleeping environment have a higher risk of poor sleep quality than who always adjust their sleep onset latency, the risk of poor sleep quality had enhanced (OR=2.83; 95% CI=2.15-3.72). Conclusions: The sleep onset latency, sleep environment and education level of primary caregiver are related to sleep quality in 1 to 3 years-old young children of New Taipei City.
