To compare dietary knowledge, behaviors and self-efficacy of black middle school students of low socioeconomic status with their white counterparts of higher socioeconomic status.
Cross-sectional, school-based survey.
Large metropolitan area in the United States.
Middle school students (1,208 of low socioeconomic and 978 of higher socioeconomic status).
Dietary behaviors, dietary knowledge, and dietary self-efficacy were assessed by questionnaire.
Differences between black students of low socioeconomic status and white students of higher socioeconomic status in the above variables.
Black students of low socioeconomic status scored significantly lower than did white students of higher socioeconomic status on several of the variables. They were more likely to consume empty calorie food, meat, and fried food and less likely to eat fruit, vegetables, dairy products, and grains; they were less knowledgeable about dietary variables; and they had significantly lower self-efficacy regarding their ability to change dietary habits.
The results of this study suggest that black students of low socioeconomic status should be targeted for early intervention related to dietary behaviors. This age group is amenable to change, and interventions designed specifically for them may result in lifetime reductions in risk of morbidity and mortality.
比较低社会经济地位的黑人和高社会经济地位的白人初中学生的饮食知识、行为和自我效能。
横断面、基于学校的调查。
美国大都市区。
初中生(低社会经济地位的 1208 人,高社会经济地位的 978 人)。
通过问卷调查评估饮食行为、饮食知识和饮食自我效能。
低社会经济地位的黑人学生和高社会经济地位的白人学生在上述变量上的差异。
低社会经济地位的黑人学生在几个变量上的得分明显低于高社会经济地位的白人学生。他们更有可能食用空卡路里食物、肉类和油炸食品,而不太可能食用水果、蔬菜、乳制品和谷物;他们对饮食变量的了解较少;并且他们改变饮食习惯的能力自我效能感明显较低。
本研究结果表明,应针对低社会经济地位的黑人学生进行早期干预,以改变他们的饮食行为。这个年龄段的人是可以改变的,专门为他们设计的干预措施可能会降低他们一生中患病和死亡的风险。
