This study assessed if there are sex differences in the relationship between amount of physical activity and depression in primary care outpatients. Participants (N= 111), referred by their family physicians, wore a heart-rate monitor for 24 hr. The two-lead monitor collected the number of beats per minute and minute-averaged horizontal movement data, e.g., from walking or moving about. All participants underwent structured clinical interviewing using the Structured Clinical Interview for DSM-IV and completed the Beck Depression Inventory-II and the Symptom Checklist-90-Revised. For the total sample, patients with low activity were more likely to be depressed (p<.006). Adults under the age of 45 (n=85) with low activity were 7.4 times more likely to be depressed than young adults who showed normal activity. However, in adults 45 or older, there was no relationship between activity and depression. In a subsample of women under the age of 55 (n=70), 91% of the low activity group and 39% of the normal activity group were diagnosed with depression (p<.003). Women in the low activity group were 15.7 times more likely to be depressed than women in the normal activity group. In contrast, there was no relationship between activity and depression in men. Additional research is needed to assess whether low activity is a potent predictor of depression in women.
本研究评估了初级保健门诊患者中身体活动量与抑郁之间的关系是否存在性别差异。由家庭医生转诊的111名参与者佩戴心率监测器24小时。双导联监测器收集每分钟心跳次数和平均每分钟水平运动数据，例如来自行走或四处活动的数据。所有参与者都使用《精神疾病诊断与统计手册》第四版的结构化临床访谈进行了结构化临床访谈，并完成了贝克抑郁量表第二版和症状自评量表90修订版。对于总样本，活动量低的患者更有可能抑郁（p<0.006）。45岁以下活动量低的成年人（n = 85）患抑郁症的可能性是活动正常的年轻人的7.4倍。然而，在45岁及以上的成年人中，活动量与抑郁之间没有关系。在55岁以下女性的一个子样本（n = 70）中，低活动量组的91%和正常活动量组的39%被诊断患有抑郁症（p<0.003）。低活动量组的女性患抑郁症的可能性是正常活动量组女性的15.7倍。相比之下，男性的活动量与抑郁之间没有关系。需要进一步的研究来评估低活动量是否是女性抑郁症的有力预测指标。
