The objective of the present study was to investigate the associated factors with short and long sleep duration at ages 11 (pre-adolescence) and 22 years old (early adulthood).
Participants of the 1993 Pelotas birth cohort with self-reported sleep records at 11 (n = 4442) and 22 (n = 3800) years were included. The total sleep time duration was categorised as short (<9 h for 11 years and <7 h for 22 years), long (>11 for 11 years and >9 for 22 years) and recommended according to the National Sleep Foundation criteria. Multinomial regression analyses were applied according to a hierarchical approach in order to investigate the associated factors with sleep duration patterns. All analyses were stratified by sex.
Higher income was associated with higher odds of short sleep duration in 11-year-old boys [OR = 1.54 (CI95%: 1.08; 2.19)] and girls [OR = 1.45 (CI95%: 1.03; 2.06)] and also with lower odds of long sleep duration in both ages. At 22 years, common mental health disorders were associated with higher odds of short sleep duration in both men [OR = 1.56 (CI95%: 1.18; 2.06)] and women [OR = 1.48 (CI95%: 1.11; 1.99)]. Sleep duration was also related to screen time and physical activity showing different association patterns according to sex and age.
Different factors may be associated with sleep duration patterns in pre-adolescence and early adulthood. Our results emphasise the importance of considering stratification analyses to identify associated factors with sleep duration since they may vary according to age and sex.
本研究的目的是调查11岁（青春期前）和22岁（成年早期）时短睡眠时长和长睡眠时长的相关因素。
纳入1993年佩洛塔斯出生队列中在11岁（n = 4442）和22岁（n = 3800）时有自我报告睡眠记录的参与者。根据美国国家睡眠基金会标准，将总睡眠时间分为短睡眠（11岁时<9小时，22岁时<7小时）、长睡眠（11岁时>11小时，22岁时>9小时）和推荐睡眠时长。采用分层方法进行多项回归分析，以调查睡眠时长模式的相关因素。所有分析均按性别分层。
较高收入与11岁男孩[比值比（OR）= 1.54（95%置信区间：1.08；2.19）]和女孩[OR = 1.45（95%置信区间：1.03；2.06）]短睡眠时长的较高几率相关，且与两个年龄段长睡眠时长的较低几率相关。在22岁时，常见心理健康障碍与男性[OR = 1.56（95%置信区间：1.18；2.06）]和女性[OR = 1.48（95%置信区间：1.11；1.99）]短睡眠时长的较高几率相关。睡眠时长还与屏幕使用时间和身体活动有关，根据性别和年龄呈现不同的关联模式。
不同因素可能与青春期前和成年早期的睡眠时长模式相关。我们的结果强调了考虑分层分析以确定睡眠时长相关因素的重要性，因为这些因素可能因年龄和性别而异。
