Associations between poor sleep and pain may be amplified for children who also have depressive or anxious symptoms. This study examined associations between child sleep at eight years and recurrent pain at nine years along with the moderating role of internalizing symptoms. Families were from a community-based, ongoing longitudinal study (N = 632 children). At eight and nine years, twins (49.2% female, 56.7% non-Latinx European American, 28.8% Latinx) and caregivers participated in assessments focused on child sleep and pain, respectively. Approximately 53% of children had pain in at least one location at least monthly. Internalizing symptoms at age eight were positively associated with number of pain sites at age nine. Lower sleep efficiencies were associated with more pain sites for children with higher levels of internalizing symptoms. Later midpoint times were associated with more pain sites for children with lower levels of internalizing symptoms. Interventions focused on improving children’s pain outcomes may consider targeting sleep behaviors and mental health.

对于也有抑郁或焦虑症状的儿童，睡眠不足和疼痛之间的关联可能会被放大。这项研究检查了 8 岁儿童睡眠与 9 岁复发性疼痛之间的关联，以及内化症状的调节作用。家庭来自一项以社区为基础的、正在进行的纵向研究（N = 632 名儿童）。在 8 岁和 9 岁时，双胞胎（49.2% 为女性，56.7% 为非拉丁裔欧洲裔美国人，28.8% 为拉丁裔）和看护人分别参加了针对儿童睡眠和疼痛的评估。大约 53% 的儿童至少每月在至少一个部位出现疼痛。八岁时的内化症状与九岁时疼痛部位的数量呈正相关。对于内化症状水平较高的儿童来说，较低的睡眠效率与更多的疼痛部位有关。对于内化症状水平较低的儿童，较晚的中点时间与更多的疼痛部位有关。专注于改善儿童疼痛结果的干预措施可以考虑针对睡眠行为和心理健康。
