Evidence suggests that depressive symptoms are associated with poorer dietary intake and inadequate physical activity; however, this association has not been examined in lower-income overweight and obese African American women. The objective of this cross-sectional study was to examine the associations between depressive symptoms and diet and physical activity in 196 women (87% African American; age, 25-51 years). Higher depressive symptoms were hypothesized to predict poorer diet quality, greater emotional eating, lower physical activity levels, and greater sedentary time. Depressive symptoms were measured using the validated short form of the Center for Epidemiological Studies Depression Scale. Dietary intake and quality were assessed using three 24-hour dietary recalls. Emotional eating was evaluated using 4 items from the emotional eating subscale of the Eating Behavior Patterns Questionnaire. Physical activity and sedentary time were objectively measured using the ActiGraph accelerometer. Linear regression models tested the associations between depressive symptoms and each dietary and physical activity outcome variable. Symptoms of depression were positively associated with total daily caloric intake from saturated fat and total sugars, as well as emotional eating scores (P < .05). Although not statistically significant, depressive symptoms were positively associated with sweetened beverage consumption (P = .06) and added sugars (P = .07). Depressive symptoms were not associated with total fat, sodium, fruit and vegetables, fast food consumption, the Alternate Healthy Eating Index score, moderate-to-vigorous physical activity, or sedentary time. Future studies should explore the mechanisms linking the identified associations between depressive symptoms and dietary intake, such as the role of emotional eating.
有证据表明,抑郁症状与较差的饮食摄入和不足的身体活动有关;然而,这种关联尚未在低收入超重和肥胖的非裔美国女性中得到研究。这项横断面研究的目的是检验196名女性(87%为非裔美国人;年龄25 - 51岁)的抑郁症状与饮食及身体活动之间的关联。研究假设较高的抑郁症状会预示较差的饮食质量、更多的情绪化进食、较低的身体活动水平以及更长的久坐时间。抑郁症状通过经过验证的流行病学研究中心抑郁量表简表进行测量。饮食摄入和质量通过三次24小时饮食回顾进行评估。情绪化进食使用饮食行为模式问卷中情绪化进食子量表的4个条目进行评估。身体活动和久坐时间使用ActiGraph加速度计进行客观测量。线性回归模型检验了抑郁症状与每个饮食及身体活动结果变量之间的关联。抑郁症状与来自饱和脂肪和总糖的每日总热量摄入以及情绪化进食得分呈正相关(P < .05)。虽然无统计学意义,但抑郁症状与含糖饮料消费(P = .06)和添加糖(P = .07)呈正相关。抑郁症状与总脂肪、钠、水果和蔬菜、快餐消费、替代健康饮食指数得分、中度至剧烈身体活动或久坐时间无关。未来的研究应探索将已确定的抑郁症状与饮食摄入之间的关联联系起来的机制,比如情绪化进食的作用。
