OBJECTIVES
Although Mexican Americans consume diets that may protect them against adverse health, dietary advantages may disappear with increased acculturation. This study examined whether the nutrient intake of second-generation Mexican-American women of childbearing age deteriorates compared with that of first-generation Mexican-American women and approximates that of White non-Hispanic women.
METHODS
Data on the absolute and relative intake of eight nutrients were obtained from a 24-hour recall and compared among 475 first-generation and 898 second-generation Mexican-American women, and among 2326 White non-Hispanic women.
RESULTS
Although first-generation Mexican-American women were of lower socioeconomic status than were second-generation or White non-Hispanic women, they had a higher average intake of protein; vitamins A, C, and folic acid; and calcium than the other two groups. Whereas the mean adequacy ratio of the eight nutrients studied was highest in first-generation Mexican women, it was lowest in their second-generation counterparts.
CONCLUSIONS
First-generation Mexican women stand a markedly lower risk of eating a poor diet than second-generation Mexican women, whose nutrient intake resembles that of White non-Hispanic women.
目的
尽管墨西哥裔美国人的饮食可能对他们的健康有益，但随着文化适应程度的提高，饮食优势可能会消失。本研究调查了第二代育龄墨西哥裔美国女性的营养摄入量与第一代墨西哥裔美国女性相比是否恶化，以及是否接近非西班牙裔白人女性的营养摄入量。
方法
通过24小时饮食回顾法获取了475名第一代和898名第二代墨西哥裔美国女性以及2326名非西班牙裔白人女性的8种营养素的绝对和相对摄入量数据，并进行了比较。
结果
尽管第一代墨西哥裔美国女性的社会经济地位低于第二代或非西班牙裔白人女性，但她们的蛋白质、维生素A、C和叶酸以及钙的平均摄入量高于其他两组。在研究的8种营养素中，第一代墨西哥女性的平均充足率最高，而第二代墨西哥女性的平均充足率最低。
结论
第一代墨西哥女性饮食不良的风险明显低于第二代墨西哥女性，第二代墨西哥女性的营养摄入量与非西班牙裔白人女性相似。
