摘要

目的:补充维生素 D 对贫血有积极影响,但贫血患者铁蛋白相关膳食模式、铁参数和维生素 D 之间的关系尚不清楚:这项横断面研究分析了 2017-2019 年全国营养与健康调查的数据,其中包括 1423 名 15 岁以上的孕妇。膳食摄入量通过半定量食物频率问卷和 24 小时膳食回忆进行评估。以血液参数为响应变量,以 32 种食物类别为预测变量,采用降序回归法确定了 FrDP。线性和二项式逻辑回归分析评估了FrDP与血清生物标志物之间的关联,并对人口统计学变量和饮食变量进行了调整。此外,还评估了FrDP与维生素D浓度之间的风险关联:FrDP解释了6个反应变量中18.5%的变化,其特点是鱼类、大豆、面筋面食、坚果、内脏肉、腌制蔬菜和海洋植物的消费量高。FrDP 与血清血红蛋白(r = 0.76)、铁(r = 0.52)、铁蛋白(r = 0.79)、叶酸(r = 0.86)和维生素 B12(r = 0.86)呈正相关。线性回归显示,FrDP 与血清铁之间存在正相关。FrDP最高三分层的女性血清铁含量较低(OR = 0.65,95% CI 0.50-0.85),但25(OH)维生素D浓度较低(OR = 1.79,95% CI 1.32-2.43):FrDP与孕妇血清铁呈正相关,但与血清25(OH)维生素D呈负相关。

A ferritin-related dietary pattern is positively associated with iron status but negatively associated with vitamin D status in pregnant women: a cross-sectional study.

Purpose: Vitamin D supplementation positively impacts anemia, but the relationship between a ferritin-related dietary pattern, iron parameters, and vitamin D in anemia is unclear.

Methods: This cross-sectional study analyzed data from the 2017-2019 National Nutrition and Health Survey, including 1423 pregnant women over 15 years old. Dietary intake was assessed using a semi-quantitative food frequency questionnaire and a 24-hour dietary recall. The FrDP was identified using reduced rank regression with blood parameters as response variables and 32 food groups as predictors. Linear and binomial logistic regression analyses evaluated the associations between the FrDP and serum biomarkers, adjusting for demographic and dietary variables. Risk associations between the FrDP and vitamin D concentrations were also assessed.

Results: The FrDP explained 18.5% of the variation in 6 response variables and was characterized by high consumption of fish, soy, gluten pasta, nuts, organ meat, pickled vegetables, and marine plants. The FrDP correlated positively with serum hemoglobin (r = 0.76), iron (r = 0.52), ferritin (r = 0.79), folate (r = 0.86), and vitamin B12 (r = 0.86). Linear regression revealed a positive association between the FrDP and serum iron. Women in the highest FrDP tertile were less likely to have low serum iron (OR = 0.65, 95% CI 0.50-0.85) but more likely to have low 25(OH) vitamin D concentrations (OR = 1.79, 95% CI 1.32-2.43).

Conclusions: The FrDP was positively associated with serum iron but negatively associated with serum 25(OH) vitamin D in pregnant women.

期刊介绍: The European Journal of Nutrition publishes original papers, reviews, and short communications in the nutritional sciences. The manuscripts submitted to the European Journal of Nutrition should have their major focus on the impact of nutrients and non-nutrients on immunology and inflammation, gene expression, metabolism, chronic diseases, or carcinogenesis, or a major focus on epidemiology, including intervention studies with healthy subjects and with patients, biofunctionality of food and food components, or the impact of diet on the environment.
