A bias in perceived risk for health outcomes, including fracture, exists.
We compared perceived risk and biases in perceived risk for fracture to fracture preventive behavior.
Women over age 55 (n = 2874) completed a survey five times over 5 years, and data was pulled from the medical record. Perceived risk was measured by asking women to rate their risk of fracture compared to similar women. Actual risk was measured using FRAX score. Bias was measured using an interaction between perceived and actual risk.
Higher perceived risk was related to lower quality of life and self-reported health, more medication and calcium use, increased bone density scan use, and less walking. Bias was only associated with less medication use. Neither perceived risk nor bias predicted medication adherence.
Perceived risk, but not bias, may predict different fracture prevention behaviors. Clinicians may need to base interventions on risk perceptions.
在包括骨折在内的健康结果的感知风险方面存在偏差。
我们比较了骨折的感知风险以及感知风险偏差与骨折预防行为之间的关系。
55岁以上的女性（n = 2874）在5年中完成了5次调查，并从病历中提取数据。通过让女性将自己的骨折风险与类似女性进行比较来测量感知风险。使用FRAX评分来测量实际风险。使用感知风险与实际风险之间的相互作用来测量偏差。
较高的感知风险与较低的生活质量和自我报告的健康状况、更多的药物和钙的使用、增加的骨密度扫描使用以及较少的步行有关。偏差仅与较少的药物使用有关。感知风险和偏差均不能预测药物依从性。
感知风险而非偏差可能预测不同的骨折预防行为。临床医生可能需要根据风险认知来制定干预措施。
