Personality disorders (PDs) have significant, long-term effects in many areas, including physical health outcomes such as increased risk for chronic disease and mortality. Although research has documented this detrimental impact in relation to long-term physical health, no one has explored the more immediate influence of disordered personality on aspects of physical functioning, such as pain level, or health-related behaviors, such as medication use. The present study examined the unique effects of PD features on physical functioning, medical resource utilization, and prescription medication use to determine potential risk associated with PDs. We studied an epidemiologically-based sample (N = 608) of Saint Louis residents (ages 55-64) over two time points (6 months apart). We found that disordered personality was significantly predictive of worse physical functioning, role limitations, fatigue, and pain at both time points, even when current health problems, the presence of depression, and health behaviors (i.e., smoking, drinking, exercise) were controlled. PD features were also predictive of increased healthcare utilization and medication use at follow-up. These results suggest that the presence of disordered personality may be an important risk factor for worse functioning, regardless of actual health status.
人格障碍（PD）在许多领域都有重大的、长期的影响，包括身体健康结果，如慢性疾病和死亡率的风险增加。尽管研究已经记录了这种与长期身体健康有关的不利影响，但没有人探索过紊乱的人格对身体功能方面的更直接影响，例如疼痛程度，或健康相关行为，如药物使用。本研究探讨了 PD 特征对身体功能、医疗资源利用和处方药物使用的独特影响，以确定与 PD 相关的潜在风险。我们研究了圣路易斯居民（年龄在 55-64 岁）的基于流行病学的样本（N=608），在两个时间点（相隔 6 个月）进行了研究。我们发现，即使在控制了当前的健康问题、抑郁的存在和健康行为（即吸烟、饮酒、运动）后，紊乱的人格在两个时间点也显著预测了较差的身体功能、角色限制、疲劳和疼痛。PD 特征也预测了随访时的医疗保健利用和药物使用的增加。这些结果表明，紊乱的人格的存在可能是功能恶化的一个重要危险因素，而与实际健康状况无关。
