This comparative study tests for ethnic differences in dietary fat consumption in a community-based sample of Hispanic and white adults with low educational attainment (< 12 years of schooling) and a separate sample of their children.
Data are presented for adults (age 20-64, n = 886) and youths (age 12-19, n = 170) from four California cities who participated in one of four sequential cross-sectional surveys (1981-1990).
After adjustment for age, sex, city of residence, and time of survey, white adults were significantly (P < 0.03) more likely than Hispanic adults to have eaten high-fat foods in the last 24 hr, such as red meat (75.7% vs 68.4%), cured meats, (39.1% vs 25.8%), and cheese (41.4% vs 32.7%). Furthermore, white adults consumed significantly (P < 0.001) more fat, as measured by percentage of calories from total fat (37.7% vs 33.3%) and saturated fat (13.7% vs 11.8%), and consumed significantly less dietary carbohydrate (45.5% vs 49.7%) and fiber (17.1 g vs 26.0 g) than Hispanic adults. Ethnic differences were similar for the youth sample (except for carbohydrates), but were generally not significant. A graded relationship was found between acculturation and dietary measures, where more acculturated Hispanics (English-speaking) were intermediate between less acculturated Hispanics (Spanish-speaking) and whites in their dietary intake.
This study illustrates the high dietary fat consumption of whites with low educational attainment, the increasing fat consumption of Hispanics at higher levels of acculturation, and the need for effective dietary interventions for low educated whites and Hispanics.
本比较研究在受教育程度较低( schooling < 12年)的西班牙裔和白人成年人及其子女的社区样本中,测试饮食脂肪摄入量的种族差异。
呈现了来自加利福尼亚四个城市的成年人(年龄20 - 64岁,n = 886)和青少年(年龄12 - 19岁,n = 170)的数据,他们参与了四项连续横断面调查之一(1981 - 1990年)。
在对年龄、性别、居住城市和调查时间进行调整后,白人成年人在过去24小时内食用高脂肪食物(如红肉,75.7%对68.4%)、腌制肉类(39.1%对25.8%)和奶酪(41.4%对32.7%)的可能性显著高于西班牙裔成年人(P < 0.03)。此外,按总脂肪热量百分比(37.7%对33.3%)和饱和脂肪(13.7%对11.8%)衡量,白人成年人摄入的脂肪显著更多(P < 0.001),而摄入的膳食碳水化合物(45.5%对49.7%)和纤维(17.1克对26.0克)显著少于西班牙裔成年人。青少年样本中的种族差异类似(除碳水化合物外),但一般不显著。在文化适应与饮食指标之间发现了一种分级关系,文化适应程度较高的西班牙裔(说英语)在饮食摄入量上介于文化适应程度较低的西班牙裔(说西班牙语)和白人之间。
本研究表明受教育程度较低的白人饮食脂肪摄入量高,文化适应程度较高的西班牙裔脂肪摄入量增加,以及对低教育程度的白人和西班牙裔进行有效饮食干预的必要性。
