Higher scores obtained using diet quality and variety indices are indicators of more optimal food and nutrient intakes and lower chronic disease risk. The aim of this paper is to describe the overall diet quality and variety in a sample of Australian adults who completed an online diet quality self-assessment tool, the Healthy Eating Quiz. The Healthy Eating Quiz takes approximately five minutes to complete online and computes user responses into a total diet quality score (out of a maximum of 73 points) and then categorizes them into the following groups: 'needs work' (<33), 'getting there' (33-38), 'excellent' (39-46), or 'outstanding' (47+). There was a total of 93,252 first-time respondents, of which 76% were female. Over 80% of respondents were between 16-44 years of age. The mean total score was 34.1 ± 9.7 points. Females had a higher total score than males ( < 0.001) and vegetarians had higher total scores than non-vegetarians ( < 0.001). Healthy eating quiz scores were higher in those aged 45-75 years compared to 16-44 years ( < 0.001). When comparing Socioeconomic Indices for Areas deciles, those most disadvantaged had a lower total score than those least disadvantaged ( < 0.001). Repeat measures showed that those who scored lowest (needs work) in their first completion increased their total score by 3.2 ± 7.4 at their second completion ( < 0.001). While the Healthy Eating Quiz data indicates that individuals receiving feedback on how to improve their score can improve their diet quality, there is a need for further nutrition promotion interventions in Australian adults.
更高的饮食质量和多样性得分表明食物和营养摄入更优，慢性病风险更低。本文旨在描述完成在线饮食质量自我评估工具“健康饮食测验”的澳大利亚成年人样本的总体饮食质量和多样性。健康饮食测验在线完成大约需要五分钟，它将用户的回答计算为总饮食质量得分（最高 73 分），然后将其分为以下几类：“需要改进”（<33 分）、“正在改进”（33-38 分）、“优秀”（39-46 分）或“杰出”（47+分）。共有 93,252 名首次回答者，其中 76%为女性。超过 80%的受访者年龄在 16-44 岁之间。平均总分为 34.1 ± 9.7 分。女性的总得分高于男性（<0.001），素食者的总得分高于非素食者（<0.001）。45-75 岁人群的健康饮食测验得分高于 16-44 岁人群（<0.001）。在比较社会经济区域指数的十分位数时，最弱势群体的总得分低于最弱势群体（<0.001）。重复测量显示，那些在第一次完成时得分最低（需要改进）的人在第二次完成时总分提高了 3.2 ± 7.4 分（<0.001）。虽然健康饮食测验数据表明，收到有关如何提高分数的反馈的个人可以改善他们的饮食质量，但澳大利亚成年人仍需要进一步的营养促进干预措施。
