Objective. To estimate the relationship between obesity (defined by both BMI and SAD) and various levels of depressive symptoms in women in the United States. Methods. This is a cross-sectional design. All data were collected from NHANES 2011-2012 and 2013-2014. The Patient Health Questionnaire (PHQ-9) was the primary variable used to index depressive symptoms. SAD was assessed using an abdominal caliper. We stratified participates into three groups according to SAD (trisection): T1: low (11.8-18.4 cm), T2: middle (18.5-22.8 cm), and T3: high (22.9-40.1 cm). Other data were collected following the NHANES protocols. We aimed to investigate the effects of obesity on the depression in the NHANES populations. Results. A total of 4477 women were enrolled in the final study population. Participants with a high SAD had the highest risk of clinical depression symptoms (, 95% CI: 1.1-1.4), which was, in particular, the case for moderate-severe depression (, 95% CI: 1.1-1.7) and severe depression (, 95% CI: 1.0-1.9). We also found a significant relationship between SAD and BMI (). We did, however, not find a significant relationship between BMI and severe depression. Conclusions. SAD had a better correlation with clinical depression symptoms than BMI, especially regarding severe depression symptoms.

美国女性抑郁症状与不同类型肥胖指标（BMI、SAD）之间的关系

客观的。评估美国女性肥胖（由 BMI 和 SAD 定义）与不同程度的抑郁症状之间的关系。方法。这是横截面设计。所有数据均来自 NHANES 2011-2012 和 2013-2014 年。患者健康问卷 (PHQ-9) 是用于索引抑郁症状的主要变量。使用腹部卡尺评估 SAD。我们根据 SAD（三等分）将参与者分为三组：T1：低（11.8-18.4 厘米），T2：中（18.5-22.8 厘米），T3：高（22.9-40.1 厘米）。其他数据是按照 NHANES 协议收集的。我们的目的是调查肥胖对 NHANES 人群抑郁症的影响。结果。最终研究人群共有 4477 名女性。SAD 较高的参与者出现临床抑郁症状的风险最高（， 95% CI：1.1-1.4），尤其是中重度抑郁症的情况（， 95% CI：1.1-1.7）和严重抑郁症（， 95% CI：1.0-1.9）。我们还发现 SAD 和 BMI 之间存在显着关系（）。然而，我们并未发现体重指数与严重抑郁症之间存在显着关系。结论。与 BMI 相比，SAD 与临床抑郁症状的相关性更好，尤其是严重抑郁症状。
