The incidence of sleep problems is increasing in children, and they are thought to contribute to pain in functional abdominal pain disorder (FAPD). In this study, we aimed to evaluate the pattern of sleep disturbance in children with FAPD and identify the associated factors. We retrospectively analyzed patients aged 12–18 years who were diagnosed with FAPD based on the Rome IV criteria. To assess sleep problems, we used the Korean version of the Pittsburgh Sleep Quality Index (PSQI-K). To evaluate factors associated with sleep disturbances, we used the odds ratios (OR) estimated in logistic regression models. Among the 66 patients evaluated, 57.6% (38/66) had a total PSQI-K score > 5, indicating a significant disturbance in sleep, 52.6% (20/38) had irritable bowel syndrome (IBS), and 47.4% (18/38) had functional abdominal pain-not otherwise specified. The mean PSQI-K score was 7.2 ± 6.0, and longer sleep onset latency was noted (26.33 ± 19.44 min) in all patients than healthy controls. Almost all PSQI-K subscales scores were elevated in patients with IBS. In univariate analysis, abdominal pain score > 7 and IBS were associated with poor sleep quality. In multivariate analysis, only IBS was associated with sleep disturbance. A relatively large proportion of patients with FAPD had sleep problems and these were more common in patients with IBS. Thus, interventions for improving sleep quality should also be considered in patients with FAPD with severe abdominal pain and IBS.

儿童睡眠问题的发生率正在增加，并且被认为是导致功能性腹痛障碍 (FAPD) 疼痛的原因之一。在这项研究中，我们旨在评估 FAPD 儿童的睡眠障碍模式并确定相关因素。我们回顾性分析了根据罗马 IV 标准诊断为 FAPD 的 12-18 岁患者。为了评估睡眠问题，我们使用韩国版的匹兹堡睡眠质量指数 (PSQI-K)。为了评估与睡眠障碍相关的因素，我们使用逻辑回归模型中估计的优势比 (OR)。在接受评估的 66 名患者中，57.6% (38/66) 的 PSQI-K 总分 > 5，表明睡眠受到显着干扰，52.6% (20/38) 患有肠易激综合征 (IBS)，47.4% (18 /38) 有功能性腹痛——未另有说明。平均 PSQI-K 评分为 7.2 ± 6.0，所有患者的入睡潜伏期均比健康对照者更长（26.33 ± 19.44 分钟）。 IBS 患者几乎所有 PSQI-K 分量表评分均升高。在单变量分析中，腹痛评分 > 7 和 IBS 与睡眠质量差相关。在多变量分析中，只有 IBS 与睡眠障碍相关。相对较大比例的 FAPD 患者存在睡眠问题，并且这些问题在 IBS 患者中更为常见。因此，对于伴有严重腹​​痛和 IBS 的 FAPD 患者，还应考虑改善睡眠质量的干预措施。
