Poor sleep quality has been shown to adversely affect neurobehavior including an increase in depression symptoms. Police officers are at increased risk of poor sleep quality due to occupational factors. This study analyzed self-reported sleep and depression data from police officers; 391 police officers from Buffalo, New York reported on sleep and depression by completing the Pittsburgh Sleep Quality Index (PSQI) and the Center for Epidemiological Studies Depression (CES-D) questionnaires. Mean CES-D scores were assessed across quintiles of PSQI. As PSQI scores increased, reflecting poorer sleep quality, CES-D scores also increased significantly indicating an increase in depression symptoms as sleep quality worsens. This trend held for both male and female officers. Mean CES-D scores across quintiles ranged from 4.72 to 12.65 in men and from 5.53 to 12.63 in women. Multivariate adjustment only very slightly attenuated the association in female officers. After adjustmnent, five of the seven PSQI components showed statistically significant associations with CES-D scores in male officers and two in female officers. Sleep quality was significantly and independently associated with depressive symnptoms as evidenced by a trend of increasing depressive symptom scores with decreasing sleep quality in both male and female officers.
睡眠质量差已被证明会对神经行为产生不利影响，包括抑郁症状的增加。由于职业因素，警察睡眠质量差的风险更高。本研究分析了警察自我报告的睡眠和抑郁数据；来自纽约州布法罗市的391名警察通过填写匹兹堡睡眠质量指数（PSQI）和流行病学研究中心抑郁量表（CES-D）问卷报告了睡眠和抑郁情况。在PSQI的五分位数中评估平均CES-D得分。随着PSQI得分的增加，反映出睡眠质量较差，CES-D得分也显著增加，表明随着睡眠质量恶化，抑郁症状增加。这种趋势在男性和女性警察中均成立。男性五分位数的平均CES-D得分在4.72至12.65之间，女性在5.53至12.63之间。多变量调整仅略微减弱了女性警察中的这种关联。调整后，PSQI的七个组成部分中有五个在男性警察中与CES-D得分显示出统计学上的显著关联，在女性警察中有两个显示出显著关联。睡眠质量与抑郁症状显著且独立相关，男性和女性警察中抑郁症状得分均随着睡眠质量下降而增加的趋势证明了这一点。
