African Americans in the United States suffer from many health disparities such as obesity, diabetes or hypertension. Lifestyle factors including diet and physical activity play an important role in prevention of these health conditions. The purpose of this research project was to assess beliefs, barriers and self-efficacy of eating a healthy diet and self efficacy of shopping for foods such as whole grains or foods designated as low fat or low sodium. Additionally, the objective was to assess beliefs about healthfulness, appropriate consumption, and protective aspect of specific foods including fruits, vegetables, and whole grains. The assessment was done using a survey instrument developed for this study. Data collection took place at two church locations. Data were obtained from 57 African Americans, mean age 50 years old (SD 12.70) completed the survey. The majority of respondents (58.1%) were females and most (75%) had at least some college education. Generally, benefits of eating healthy foods received considerably higher scores compared to barriers of eating healthy. A belief that healthy foods would help to take care of one's body received the highest mean score while a belief that healthy foods are too expensive had the highest score from all barriers. The results showed high self-efficacy of eating and purchasing healthy foods, high awareness of knowledge regarding foods associated with disease prevention but low awareness of recommendations for fruits and vegetables. The high scores for benefits, self-efficacy and knowledge regarding eating healthy foods did not translate into the perception of intake of such foods. Most participants believed that they do not eat enough of healthy foods. Interventions design to help African Americans make dietary changes should be culturally relevant and should involved working on a community level utilizing messages that are familiar and relevant to African Americans.
美国的非裔美国人面临着许多健康差异,如肥胖、糖尿病或高血压。生活方式因素,如饮食和体育活动,在预防这些健康状况方面起着重要作用。本研究项目的目的是评估非裔美国人关于健康饮食的信念、障碍和自我效能感,以及购买全麦或低脂、低钠食品的自我效能感。此外,研究的目的还在于评估对具体食物(如水果、蔬菜和全麦)的健康程度、适当消费和保护作用的信念。该评估使用为此项研究开发的调查工具进行。数据收集在两个教堂地点进行。共有 57 名非裔美国人完成了调查,平均年龄 50 岁(标准差 12.70)。大多数受访者(58.1%)为女性,大多数人(75%)至少接受过一些大学教育。总的来说,食用健康食品的好处得分明显高于食用健康食品的障碍。食用健康食品有助于照顾自己的身体这一信念获得了最高的平均得分,而健康食品太贵这一信念则在所有障碍中得分最高。结果表明,食用和购买健康食品的自我效能感较高,对与疾病预防相关的食品的知识意识较高,但对水果和蔬菜的推荐意识较低。食用健康食品的好处、自我效能感和知识的高分并没有转化为对这些食品摄入的感知。大多数参与者认为他们没有摄入足够的健康食品。帮助非裔美国人改变饮食的干预措施应该具有文化相关性,并应在社区层面上进行,利用对非裔美国人来说熟悉和相关的信息。
