OBJECTIVES
Self-reporting provides useful information for assessing the risk factors of osteoporotic fractures in large cohort studies. However, to data, no studies in Japan have confirmed the accuracy of this approach in this context. The aim of the study reported here was to determine the positive predictive value (PPV) for the self-reporting of fractures.
METHODS
A total of 133 participants of the Oguni cohort in the Japan Public Health Center-based Prospective Study who reported a vertebral, upper limb, or hip fracture on the 15-year follow-up questionnaire survey were evaluated. The accuracy of fractures was confirmed by cross-referencing medical records.
RESULTS
The average age of the participants was 72.4 (standard deviation 7.9) years. The PPV for vertebral fracture in the last 15 years was 17/20 (85.0%) for women and 2/9 (22.2%) for men, for a total of 19/29 (65.5%). PPVs for upper limb and hip fractures were as low as 30/68 (44.1%) and 12/22 (54.5%), respectively.
CONCLUSION
Female self-reporting provided PPVs suitable for symptomatic vertebral fracture over 15 years and can be used as an outcome measure in large cohort studies in Japan.
目的
在大型队列研究中，自我报告提供了评估骨质疏松性骨折危险因素的有用信息。然而，迄今为止，日本尚无研究证实这种方法在该背景下的准确性。本报告研究的目的是确定骨折自我报告的阳性预测值（PPV）。
方法
对日本公共卫生中心前瞻性研究奥羽队列的 133 名参与者进行了评估，这些参与者在 15 年随访问卷调查中报告了椎体、上肢或髋部骨折。通过交叉参考病历来确认骨折的准确性。
结果
参与者的平均年龄为 72.4（标准差 7.9）岁。女性在过去 15 年中椎体骨折的 PPV 为 17/20（85.0%），男性为 2/9（22.2%），总计为 19/29（65.5%）。上肢和髋部骨折的 PPV 低至 30/68（44.1%）和 12/22（54.5%）。
结论
女性自我报告在超过 15 年的时间里提供了适合症状性椎体骨折的 PPV，可以作为日本大型队列研究的结局指标。
