目標：本研究旨以縱向視野探索青少年時期家庭脈絡（包括，家庭結構、親子關係、父母監管）與成年初期睡眠行為間之關聯，及離家過渡在這之間的潛在調節機制．方法：納入台灣青少年成長歷程研究（簡稱TYP）中完整參與高二至大二時期之受訪者（N=2,123，共兩世代：2005年至2007年的國一世代和2003年至2004年的國三世代），並以多元邏輯斯迴歸分析睡眠時間（短、建議〔7h-9h〕、長）；負二項迴歸分析失眠症狀（三種症狀加總）。結果：青少年時期生於單親家庭者，其成年初期有較高可能睡眠時間相對長（相對風險比 [Relative Risk Ratio] RRR 1.52，95% CI 1.02-2.25）；與父母關係較佳或受父母較多監管者，日後則較低可能睡眠時間相對短（RRR 0.75，95% CI 0.61-0.92；RRR 0.91，95% CI 0.85-0.97）。此外，親子關係較佳者，日後失眠症狀風險也相對低（發生率比 [Incidence Rate Ratio] IRR 0.90，95% CI 0.83-0.98）。進一步探究於成年初期離家者，可見親子關係和父母監管與睡眠行為仍存顯著相關。結論：青少年時期所處家庭脈絡與成年初期睡眠行為間存在縱向關聯．為預防後續出現不建議睡眠時數和失眠症狀，青少年時期親子關係和父母監管為建議優先介入措施。

Objectives: This study seeks to delineate the effects of family context during adolescence, namely family structure, parent-child relationship, and parental monitoring, and their longitudinal associations with sleep behaviors during young adulthood, with a focus on a possible moderating effect of leaving home transition. Methods: Data were retrieved from the Taiwan Youth Project (TYP) (N=2,123, and consisted of a two-cohort sample from 12th grade at school up to an age of around 20 years, these cohorts consisted of a 7th-grade one from 2005 to 2007 and a 9th-grade one from 2003 to 2004). Sleep duration (short, recommended [7h-9h], and long) was analyzed by multinomial logistic regression, while insomnia symptoms were analyzed by negative binomial regression. Results: Youth living in a one-parent family during adolescence had an increased risk of long sleep duration during young adulthood (Relative Risk Ratio [RRR] 1.52, 95% CI 1.02- 2.25); whereas those with a more positive relationship with parents, or receiving more parental monitoring, were less likely to experience short sleep duration (RRR 0.75 95% CI 0.61-0.92; RRR 0.91, 95% CI 0.85-0.97). Moreover, youth with a more positive parent-child relationship were also found to be at lower risk of insomnia symptoms (Incidence Rate Ratio [IRR] 0.90, 95% CI 0.83-0.98). Furthermore, when the sample was restricted to those who had left home during young adulthood, the effects of a positive parent-child relationship and parental monitoring remain significant and had the same effect on the various sleep behaviors. Conclusions: Our results suggest that the importance of family context and its longitudinal association with sleep behaviors. To prevent an unrecommended sleep duration and the development of insomnia symptoms during young adulthood, early intervention that targets parent-child relationships and parental monitoring are suggested as a priority.
