Depression is associated with a decreased cardiorespiratory fitness, and physical activity [PA] levels, higher rates of obesity, and dysfunction in autonomic control of heart rate [HR]. However, these parameters were mostly recorded with indirect methods. Thus, the aim of the current study was to investigate the relationships between depression scores and objective measures of body fatness, autonomic indices (i.e. HRV and HRR), cardiorespiratory fitness and PA levels; and subsequently to present the best predictive models of depression scores for this population, based on these variables. Thirty-five non-exercising women (26-43 years; maximal oxygen consumption [VOmax] ~ 17.4-38.3 mL/kg/min) volunteered for participation in this study. All participants responded to the Beck Depression Inventory [DBI] and were evaluated for body mass index [BMI], percentage of body fat, sum of skinfolds, and VOmax. Subsequently, over four consecutive days, an orthostatic test and a submaximal exercise on a cycle ergometer were performed to record HRV and HRR, respectively. In addition, incidental PA was recorded during 5 consecutive days using accelerometers. depression scores were related to VOmax ( = -0.446, = 0.007) and the sum of skinfolds ( = 0.434, = 0.009). Several stepwise multiple linear regression models were performed and only VOmax was revealed as an independent predictor of the Beck scores (ß = -0.446, = 0.199, = 0.007). The present study revealed that VOmax and the sum of skinfolds were moderately related to depression scores, while VOmax was the only independent predictor of depression scores in female workers.
抑郁症与心肺适能下降、身体活动（PA）水平降低、肥胖率升高以及心率（HR）自主控制功能障碍有关。然而，这些参数大多是通过间接方法记录的。因此，本研究的目的是调查抑郁评分与身体脂肪客观测量指标、自主指标（即心率变异性[HRV]和心率恢复[HRR]）、心肺适能和PA水平之间的关系；随后，基于这些变量，给出该人群抑郁评分的最佳预测模型。35名不运动的女性（年龄在26 - 43岁之间；最大摄氧量[VOmax]约为17.4 - 38.3毫升/千克/分钟）自愿参与本研究。所有参与者都完成了贝克抑郁量表[DBI]，并接受了体重指数[BMI]、体脂百分比、皮褶厚度总和以及VOmax的评估。随后，连续四天分别进行了直立试验和在自行车测力计上的次最大运动，以记录HRV和HRR。此外，连续五天使用加速度计记录日常PA。抑郁评分与VOmax（r = -0.446，p = 0.007）和皮褶厚度总和（r = 0.434，p = 0.009）相关。进行了几个逐步多元线性回归模型，结果显示只有VOmax是贝克评分的独立预测因子（β = -0.446，SE = 0.199，p = 0.007）。本研究表明，VOmax和皮褶厚度总和与抑郁评分中度相关，而VOmax是女性工作者抑郁评分的唯一独立预测因子。
