Depression affects more than 15 million Americans in a given year. Compared to physical health, less is known about the affect of diet quality on symptoms of depression.
This study investigated the relationship between diet quality and reported symptoms of depression in a low-income urban population.
SUBJECTS/SETTING: Subjects included 1,118 African-American and white adults, aged 30 to 64 years, living in Baltimore, MD, and represented a subsample of the initial examination and recruitment phase of the Healthy Aging in Neighborhoods of Diversity across the Life Span study.
Nutrition data were based on two 24-hour dietary recalls collected by trained interviewers using the US Department of Agriculture Automated Multiple Pass Method. Diet quality was calculated using the US Department of Agriculture Healthy Eating Index (HEI)-2005. Depressive symptoms were assessed by a trained interviewer using the Center for Epidemiologic Studies Depression scale.
Both linear and logistic regression analyses were used to examine whether or not diet quality was associated with depressive symptoms. The dependent variable was depressive symptoms and independent variables included HEI-2005, race, sex, age, education, income, and food-assistance program participation.
Mean HEI-2005 score was 52.17+/-0.40 (out of 100). Mean Center for Epidemiologic Studies Depression scale score was 11.64+/-0.25 (out of 40). Diet quality was significantly associated with reported symptoms of depression. However, income was a significantly stronger predictor of depression compared to diet quality, education, and sex.
Registered dietitians should be aware of relationships between psychological status and nutritional health when assisting clients to better manage their food choices to improve their overall health and quality of life.
在特定年份，抑郁症影响着超过1500万美国人。与身体健康相比，饮食质量对抑郁症症状的影响了解较少。
本研究调查了低收入城市人群中饮食质量与报告的抑郁症症状之间的关系。
研究对象/研究背景：研究对象包括1118名年龄在30至64岁之间的非裔美国人和白人成年人，他们居住在马里兰州巴尔的摩市，是“全生命周期多元社区健康老龄化”研究初始检查和招募阶段的一个子样本。
营养数据基于经过培训的访谈员使用美国农业部自动多次通过法收集的两次24小时饮食回忆。饮食质量使用美国农业部2005年健康饮食指数（HEI）进行计算。抑郁症状由经过培训的访谈员使用流行病学研究中心抑郁量表进行评估。
使用线性和逻辑回归分析来检验饮食质量是否与抑郁症状相关。因变量是抑郁症状，自变量包括HEI - 2005、种族、性别、年龄、教育程度、收入和食品援助计划参与情况。
HEI - 2005的平均得分是52.17±0.40（满分100）。流行病学研究中心抑郁量表的平均得分是11.64±0.25（满分40）。饮食质量与报告的抑郁症症状显著相关。然而，与饮食质量、教育程度和性别相比，收入是抑郁症的一个显著更强的预测因素。
注册营养师在协助客户更好地管理食物选择以改善其整体健康和生活质量时，应了解心理状态与营养健康之间的关系。
