To examine baseline fat-related dietary behaviors of white, Hispanic, and black participants in Minimal Contact Education for Cholesterol Change, a National Institutes for Health-funded cholesterol screening and education project conducted in New England.
A sample of 9,803 participants who joined the study at baseline (n=7,817 white; n=1,425 Hispanic; and n=561 black).
Participants completed baseline questionnaires that included demographic and psychosocial items as well as the Food Habits Questionnaire, a dietary assessment tool measuring fat-related dietary behaviors. They also had their blood cholesterol level and height and weight measured.
Analysis of variance (ANOVA) was used to compare racial/ethnic groups on continuous demographic variables, and the chi(2) test of association was used to compare groups on demographic categorical variables. Multivariate analysis of variance (MANOVA) was used to compare mean differences between racial/ethnic groups on six behavioral subscales (Fat Factors) differentiating domains of behavior related to fat intake and to compare 27 individual fat-related dietary behaviors.
After adjusting for sex, age, marital status, education, employment status, and percent time lived in the United States, white participants had the lowest Food Habits Questionnaire summary score (2.44) (indicating a lower fat diet), followed by Hispanic (2.61) and black (2.68) participants. The three ethnic groups also differed on the prevalence of Fat Factors and specific fat-related dietary behaviors. White participants were more likely to use lower-fat alternatives, to avoid frying, to replace meat, and to modify meat to make it lower in fat. However, they were least likely to eat fruits and vegetables for snacks and desserts. Hispanic participants were more likely to engage in fat-avoidance behaviors and to eat fruits and vegetables for snacks and desserts. Black participants were less likely to eat meatless meals and modify meats to make them lower in fat. Black and Hispanic participants were more likely than white participants to fry foods. Hispanics were less likely to read food labels for nutrition information. The most and least prevalent fat-related behaviors also differed by each ethnic group, showing that different behaviors were more and less easily implemented by each ethnic group.
CONCLUSIONS/APPLICATIONS: The results of this study suggest that there is a need for improvement in dietary behaviors related to fat intake, especially for blacks and Hispanics, and that the specific dietary behavior issues differ widely by ethnicity. These results can be used by nutrition educators and researchers to help them decide what messages to emphasize in dietary counseling, nutrition education programs, and materials. The results can also be used to help design better dietary assessment tools and more effective interventions for culturally diverse populations.
在“胆固醇变化的最小接触教育”项目中,研究新英格兰地区白人、西班牙裔和黑人参与者与脂肪相关的基线饮食行为。该项目是一项由美国国立卫生研究院资助的胆固醇筛查和教育项目。
9803名在基线时加入研究的参与者样本(n = 7817名白人;n = 1425名西班牙裔;n = 561名黑人)。
参与者完成基线调查问卷,其中包括人口统计学和心理社会学项目,以及“饮食习惯问卷”,这是一种测量与脂肪相关饮食行为的饮食评估工具。他们还测量了血液胆固醇水平、身高和体重。
方差分析(ANOVA)用于比较不同种族/族裔群体在连续人口统计学变量上的差异,卡方关联检验用于比较不同群体在人口统计学分类变量上的差异。多变量方差分析(MANOVA)用于比较不同种族/族裔群体在区分与脂肪摄入相关行为领域的六个行为子量表(脂肪因子)上的平均差异,并比较27种与脂肪相关的个体饮食行为。
在对性别、年龄、婚姻状况、教育程度、就业状况以及在美国居住的时间百分比进行调整后,白人参与者的“饮食习惯问卷”总分最低(2.44)(表明脂肪摄入量较低的饮食),其次是西班牙裔(2.61)和黑人(2.68)参与者。这三个种族群体在脂肪因子的患病率和特定的与脂肪相关的饮食行为方面也存在差异。白人参与者更有可能使用低脂替代品、避免油炸、替代肉类以及改变肉类使其脂肪含量降低。然而,他们最不可能将水果和蔬菜作为零食和甜点食用。西班牙裔参与者更有可能采取避免脂肪的行为,并将水果和蔬菜作为零食和甜点食用。黑人参与者不太可能吃无肉餐,也不太会改变肉类使其脂肪含量降低。黑人和西班牙裔参与者比白人参与者更有可能油炸食物。西班牙裔参与者阅读食品营养标签的可能性较小。每个种族群体中最普遍和最不普遍的与脂肪相关的行为也有所不同,这表明不同的行为在每个种族群体中实施起来难易程度不同。
结论/应用:本研究结果表明,与脂肪摄入相关的饮食行为需要改善,尤其是黑人和西班牙裔,并且特定的饮食行为问题因种族差异很大。营养教育工作者和研究人员可以利用这些结果来帮助他们决定在饮食咨询、营养教育项目和材料中强调哪些信息。这些结果还可用于帮助设计更好的饮食评估工具以及针对文化多元群体的更有效的干预措施。
