睡眠對於發展中的兒童至關重要，良好的睡眠有助於他們的身心健康、認知發展和學習成就，近期研究更發生3C產品使用行為與睡眠品質息息相關。充足的睡眠時間和高品質的睡眠有助於提升兒童的專注力、記憶力和情緒調節能力，兒童的生長發育和整體健康狀態以及3C產品使用行為的關係為何值得進一步探討。目的：本研究旨在探討國小兒童的3C使用行為、睡眠行為、睡眠品質與身體質量指數之間的相關情形。方法：以一百三十四名臺南地區小學為研究對象，以簡易睡眠日誌、PSQI量表、兒童睡眠習慣問卷及兒福聯盟3C生活行為問卷作為研究工具，探討睡眠行為和生活行為與兒童的身體質量指數 (body mass index, BMI) 的關聯。統計分析：以皮爾遜積差相關進行指標之間的關聯，又以單因子變異數進行受試者的分群並比較其間差異。結果：本研究發現，使用多種3C產品的兒童其類睡症狀顯著低於只使用一種3C產品的兒童。假日使用4～5小時3C產品的兒童BMI顯著高於其他時間段，使用2～3小時和3～4小時的兒童夜間醒來次數顯著高於其他時間段。睡前使用3C產品的兒童平均身高顯著高於未使用者。家庭關係親近的兒童其身高和體重大於疏離和無影響組，疏離家庭的兒童其類睡症狀較為嚴重。結論：本研究的結果支持了類睡症對兒童睡眠品質的負面影響，以及假日使用3C產品時間過長對入睡延遲的影響。未來的研究應關注3C產品使用對其他健康指標的潛在影響，以全面了解3C產品使用對兒童健康的影響。

Sleep is crucial for developing children, as good sleep contributes to their physical and mental health, cognitive development, and academic achievements. Recent studies have shown the close relationship between the use of 3C (computers, communications, and consumer electronics) products and sleep quality. Adequate sleep duration and high-quality sleep help enhance children's attention, memory, and emotional regulation abilities. It is important to further explore the relationship between children's growth and development, overall health status, and the use of 3C products. Objective: The purpose of this study is to investigate the relationships among sleep behaviors, sleep quality, the use of 3C products, and Body Mass Index (BMI) in elementary school children. Methods: Elementary school children from the Tainan area were selected as subjects (N=134). Research tools included a simple sleep diary, the Pittsburgh Sleep Quality Index (PSQI), the Children's Sleep Habits Questionnaire, and the Child Welfare League Foundation's 3C Life Behavior Questionnaire. These tools were used to explore the relationship between sleep behaviors, lifestyle behaviors, and children's BMI. Statistical Analysis: Pearson’s correlation and one-way ANOVA were used to analyze the correlations. Results: The study found that children using multiple types of electronic devices (3C products) had significantly lower sleep disturbance scores compared to those using only one type. Children who used 3C products for 4-5 hours on holidays had significantly higher BMI than those using them for other durations, while those using them for 2-3 hours and 3-4 hours had significantly more night awakenings. Additionally, children using 3C products before bed were significantly taller than those who did not. Children from close family relationships had higher height and weight compared to those from distant or unaffected family relationships, while children from distant family relationships showed more severe sleep disturbances. Conclusion: The results of the current study support the negative impact of parasomnia on children's sleep quality and the effect of prolonged use of 3C products on sleep onset latency during holidays. Future research should focus on the potential impact of 3C product usage on other health indicators for further clarifying the effects of 3C product usage on children's health.
