Abstract

Background and purpose: Low dietary folate intake has been associated with depression outcomes, but few studies have been reported on the association in diverse populations. Using data from the National Health and Nutrition Examination Survey (NHANES), we examined the relationship between depression and folate intake from diet and supplementation in non-Hispanic whites, Hispanics and African Americans.

Methods: 3,687 adult respondents from the 2009-2010 NHANES cycle were included. Statistical methods for analyzing data from complex survey sample designs were used to assess differences by race/ethnicity in demographic, behavioral, dietary and depression variables and to assess the relationship between depression and folate, adjusting for confounding variables using multivariable logistic regression.

Results: We observed significant (p < 0.01) differences by race/ethnicity for all demographic, behavioral, dietary and depression variables, except for physical activity. The relationship between dietary folate and depression significantly differed by race/ethnicity (p = 0.03), with an inverse and significant association in Hispanics only (OR= 0.25; 95% CI= 0.09 - 0.70.; p for trend = 0.02).

Conclusion: These data suggest that a diet high in folate, such as from dark green leafy vegetables, may be associated with a reduced odds for depression, and specifically, Hispanics may benefit from nutrition education to potentially reduce depression in the population.

三个种族/族裔群体中叶酸总摄入量与抑郁症之间的关系。
背景和目的:低叶酸摄入与抑郁症有关,但在不同人群中很少有相关研究报道。利用国家健康与营养调查(NHANES)的数据,我们研究了非西班牙裔白人、西班牙裔美国人和非洲裔美国人从饮食和补充剂中摄入叶酸与抑郁症之间的关系。方法:选取2009-2010年NHANES周期的3687名成人调查对象。采用统计方法分析来自复杂调查样本设计的数据,评估不同种族/民族在人口统计学、行为、饮食和抑郁变量方面的差异,评估抑郁与叶酸之间的关系,并使用多变量逻辑回归对混杂变量进行调整。结果:我们观察到除体育活动外,所有人口统计学、行为、饮食和抑郁变量在种族/民族之间存在显著差异(p < 0.01)。膳食叶酸与抑郁症之间的关系因种族/民族而有显著差异(p = 0.03),仅在西班牙裔中呈显著负相关(OR= 0.25;95% ci = 0.09 - 0.70。P代表趋势= 0.02)。结论:这些数据表明,富含叶酸的饮食,如深绿色叶蔬菜,可能与降低抑郁症的几率有关,特别是,西班牙裔可能受益于营养教育,以潜在地减少人口中的抑郁症。
