老年患者对功能性便秘症状回忆的准确性评价

The accuracy of symptom recall of functional constipation in elderly patients

目的了解老年患者对功能性便秘症状回忆的准确性及其影响因素。方法纳人年龄≥60岁、符合罗马Ⅲ诊断标准的功能性便秘患者115例。本研究中，患者回忆报告便秘病程和最近3个月6个便秘症状的频度和程度，称为回忆症状；在随后2周内记录症状日记，称为日记症状；由独立评判员对2项症状按统一表格和标准进行症状评分，以日记症状为标准，分析回忆症状的一致性及影响回忆准确性的因素。结果共纳入患者115例，年龄（70．1±6．5）岁。回忆症状和日记症状总分分别为（27．6±7．4）分和（26．1±7．6）分。回忆症状总计分和日记症状总计分一致性较好[线性回归方程截距0．437（95％CI：-1．917～2．790），回归系数0．930（95％CI：0．848～1．013）]，各个便秘症状计分一致性良好（均为k〉0．75）。便秘症状回忆的准确性受性别、年龄、体力劳动强度和家庭经济情况的影响（P〈0．05），与受教育程度和便秘病程、严重程度、分型无关（P〉0．05）。结论老年患者对功能性便秘症状的回忆准确性较高，性别、年龄、体力劳动强度、家庭经济状况等因素，可影响患者对个别便秘症状回忆的准确性。

Objective To evaluate the accuracy of symptom recall of functional constipation （FC） and its potential influencing factors in elderly patients. Methods All enrolled patients were 60 years old, and met Rome 111 FC diagnostic criteria. At the beginning of study, all subjects reported the duration of constipation, frequency and severity of 6 constipated symptoms during the past 3 months （recall symptoms）; then they took diary for two weeks （diary symptoms）. Symptom score was evaluated by the independent investigators according to the unified and standard forms. The consistency of recalled symptoms and diary symptoms, and the potential influencing factors for the accuracy of recalled symptoms were analyzed. Results 115 patients were enrolled in this study, with average age of （70. 1± 6.5） years old. The overall scores of recall symptoms and diary symptoms are （27.6±7.4） and （26.1±7.6） respectively. The overall score of recalled symptoms had a good consistency with the overall score of diary symptoms [equation of linear regression intercept 0. 437 （95%CI： --1.917-2.790）, regression coefficient 0.930（95% CI： 0.848 1.013）1, and the good consistency were found in the score of each constipation symptom （all k〉0.75）. Gender, age, labor intensity and economic situation influenced the accuracy of symptom recall in FC patients （all P〈 0.05）, but education level, duration and severity of constipation, subtype of FC were not the influencing factors for the accuracy of symptom recall （all P〉0.05）. Conclusions The accuracy of symptom recall is high in elderly patients with FC, and gender, age, labor intensity and economic situation might influence the recall accuracy of individual constipation symptom.
