BACKGROUND Somatic symptom and related disorders (SSRDs) and pain are highly comorbid in the pediatric population. Little is known about the prevalence of pain and factors that may predispose and perpetuate pain in hospitalized youth with SSRD. OBJECTIVE To describe the prevalence of pain and widespread pain symptoms in hospitalized youth with SSRD and describe differences between patients who endorsed limited (1-4 sites) versus widespread (5-8 sites) pain. METHODS Retrospective chart reviews were conducted of pediatric patients with SSRD seen over a 32-month period at a tertiary pediatric hospital and assessed by the psychiatry consultation service. During admission, patients completed the Childhood Somatization Inventory, which assessed pain and other physical symptoms. Descriptive statistics, one-way analysis of variances, Pearson's χ2, stepwise linear regressions, and internal consistency analyses were used. RESULTS Of the 219 patients (aged 8-18 y), 97% reported pain symptoms, and of those reporting pain (n = 213), 48% reported widespread pain. Patients with widespread pain had greater rates of comorbid depression (P = 0.012), neglect (P = 0.016), family psychiatric history (P = 0.013), diagnostic tests/procedures (P = 0.012), and prescribed opioid use (P = 0.016), when other medical and demographic factors were considered. When compared dichotomously to youth with limited pain, there was no difference in prevalence of medical conditions; however, patients with widespread pain had higher rates of trauma and stressor-related disorders (P = 0.017), sexual abuse (P = 0.031), emotional abuse (P = 0.041), and prior child protective service involvement (P = 0.011). CONCLUSIONS Pain symptoms and widespread pain are common in medically hospitalized youth with SSRD, with unique psychiatric and psychosocial factors associated with widespread pain.

患有躯体症状和相关疾病的儿科住院患者疼痛的患病率、模式和相关性

背景 躯体症状及相关疾病 (SSRD) 和疼痛在儿科人群中高度共存。对 SSRD 住院青年的疼痛患病率和可能诱发和持续疼痛的因素知之甚少。目的 描述 SSRD 住院青年疼痛和广泛疼痛症状的患病率，并描述支持有限（1-4 个部位）与广泛（5-8 个部位）疼痛的患者之间的差异。方法 对在三级儿科医院就诊 32 个月并由精神病学咨询服务机构评估的 SSRD 儿科患者进行回顾性图表审查。在入院期间，患者完成了童年躯体化量表，用于评估疼痛和其他身体症状。描述性统计、单向方差分析、Pearson χ2、使用逐步线性回归和内部一致性分析。结果 在 219 名患者（8-18 岁）中，97% 报告了疼痛症状，在报告疼痛的患者中（n = 213），48% 报告了广泛性疼痛。广泛疼痛的患者共患抑郁症 (P = 0.012)、忽视 (P = 0.016)、家族精神病史 (P = 0.013)、诊断测试/程序 (P = 0.012) 和处方阿片类药物使用 (P = 0.016) 的发生率更高)，当考虑其他医疗和人口因素时。与疼痛有限的青年进行二分类比较时，医疗状况的患病率没有差异；然而，广泛疼痛的患者有较高的创伤和压力相关疾病（P = 0.017）、性虐待（P = 0.031）、情感虐待（P = 0.041）和先前参与儿童保护服务（P = 0.011）的发生率。
