镉（Cd）是一种有毒金属，存在于某些食物中。关于镉暴露与营养和食物组消费的关系的证据有限，几乎没有关于饮食模式的信息。目的是评估饮食和尿镉之间的关联，并探讨金属浓度是否会根据某些营养素的摄入量而变化。采用串联质谱法测定了墨西哥北方891名女性居民的尿镉浓度。我们通过食物频率问卷获得食物消费量，并使用先前定义的食物组和因子分析估计的饮食模式。我们发现镉和非淀粉类蔬菜的每日消费量之间存在正相关（CI = 0.067，95% CI 0.030，0.1023），豆类（= 0.139，95%CI 0.065，0.213）和加工肉类（= 0.163，95%CI 0.035.0.291），以及西方（= 0.083，95%CI：0.027.0.139）和谨慎饮食模式（= 0.035，95%CI：-0.020，0.091）。相比之下，我们观察到与植物油组呈负相关（= −0.070，95%CI −0.125，−0.014）。此外，我们发现50岁以下的女性中镉的浓度较高，铁的摄入量低于推荐水平。食物是暴露于这种金属的来源，同时提供调节其代谢的营养素。制定膳食指南以减少镉暴露对健康的影响是很重要的。
Cadmium (Cd) is a toxic metal found in some foods. There is limited evidence about the relationship of Cd exposure with nutrient and food groups consumption, and almost no information regarding dietary patterns. The objective was to evaluate the association between diet and urinary Cd, and to explore whether metal concentrations vary according to the intake of some nutrients. Urinary Cd concentrations of 891 female residents of northern Mexico were determined by tandem mass spectrometry. We obtained food consumption through a food frequency questionnaire and we used previously defined food groups and estimated dietary patterns by factor analysis. We found positive associations between Cd and daily consumption of non-starchy vegetables (ß = 0.067, 95% CI 0.030, 0.1023), legumes (ß = 0.139, 95% CI 0.065, 0.213) and processed meats (ß = 0.163, 95% CI 0.035.0.291), as well as the Western (ß = 0.083, 95% CI: 0.027.0.139) and Prudent dietary patterns (ß = 0.035, 95% CI: −0.020, 0.091). In contrast, we observed a negative association with the vegetable oil group (ß = −0.070, 95% CI −0.125, −0.014). In addition, we found higher concentrations of Cd in women under 50 years of age with a lower iron intake than recommended. Food is a source of exposure to this metal and at the same time provides nutrients that modulate its metabolism. It is important to generate dietary guidelines to reduce the health effects of Cd exposure.
