Diet is a modifiable contributor to health. The lack of adherence to recommended dietary guidelines may contribute to the disproportionate burden of obesity and other chronic conditions observed in the Deep South region of the United States. The objective of this cross-sectional study was to describe food group intake and diet quality by race and weight status of women in the Deep South. Study participants were eighty-nine healthy female volunteers (56 % black, 44 % white, mean age 39⋅7 ± 1⋅4 years) recruited from Birmingham, AL, USA. Body Mass Index (BMI) determined weight status (non-obese/obese). Healthy Eating Index-2010 (HEI-2010) calculated from dietary recalls assessed diet quality. Wilcoxon sum-rank test compared HEI-2010 scores by race and weight status. analysis compared the percentage of women who achieved maximum points for HEI-2010 index food components by subgroup. Caloric and macronutrient intake did not differ by race or weight status (mean kcal 1863⋅0 ± 62⋅0). Median Total HEI-2010 Score for the sample was 51⋅9 (IQR: 39⋅1-63⋅4). Although there was no statistical difference in diet quality by race, more whites achieved the maximum score for vegetable intake compared to blacks, while blacks reported higher total fruit intake. Non-obese women reported better diet quality (56⋅9 46⋅1; = 0⋅04) and eating more whole fruits, and more achieved the maximum score for protein from plant and seafood sources. In summary, differences in diet quality were observed by weight status, but not race among this sample. These results point to tailored dietary interventions for women in metropolitan areas of Alabama, USA.
饮食是健康的一个可改变的影响因素。不遵守推荐的饮食指南可能会导致肥胖和其他慢性疾病在美国南部地区不成比例的负担。本横断面研究的目的是描述美国南部地区女性的食物组摄入量和饮食质量与种族和体重状况的关系。研究参与者是 89 名来自美国阿拉巴马州伯明翰的健康女性志愿者(56%为黑人,44%为白人,平均年龄 39.7±1.4 岁)。体重指数(BMI)确定体重状况(非肥胖/肥胖)。从膳食回顾中计算出的健康饮食指数-2010(HEI-2010)评估饮食质量。Wilcoxon 总和秩检验比较了种族和体重状况的 HEI-2010 评分。方差分析比较了按亚组达到 HEI-2010 指数食物成分满分的女性百分比。热量和宏量营养素的摄入量不因种族或体重状况而有所不同(平均热量 1863.0±62.0)。样本的总 HEI-2010 评分中位数为 51.9(IQR:39.1-63.4)。尽管种族之间的饮食质量没有统计学差异,但与黑人相比,更多的白人达到了蔬菜摄入量的最高分,而黑人报告的总水果摄入量较高。非肥胖女性的饮食质量较好(56.9±46.1;=0.04),并且食用更多的完整水果,并且更多的人达到了植物和海鲜来源蛋白质的最高分。总之,在这个样本中,体重状况而不是种族会导致饮食质量的差异。这些结果表明,在美国阿拉巴马州的大都市地区,需要针对女性进行有针对性的饮食干预。
