Abstract

The aim of this study was to explore the associations between diet quality, socio-demographic measures, smoking, and weight status in a large, cross-sectional cohort of adults living in Yorkshire and Humber, UK. Data from 43, 023 participants aged over 16 years in the Yorkshire Health Survey, 2nd wave (2013-2015) were collected on diet quality, socio-demographic measures, smoking, and weight status. Diet quality was assessed using a brief, validated tool. Associations between these variables were assessed using multiple regression methods. Split-sample cross-validation was utilised to establish model portability. Observed patterns in the sample showed that the greatest substantive differences in diet quality were between females and males (3.94 points; P < 0.001) and non-smokers vs smokers (4.24 points; P < 0.001), with higher diet quality scores observed in females and non-smokers. Deprivation, employment status, age, and weight status categories were also associated with diet quality. Greater diet quality scores were observed in those with lower levels of deprivation, those engaged in sedentary occupations, older people, and those in a healthy weight category. Cross-validation procedures revealed that the model exhibited good transferability properties. Inequalities in patterns of diet quality in the cohort were consistent with those indicated by the findings of other observational studies. The findings indicate population subgroups that are at higher risk of dietary-related ill health due to poor quality diet and provide evidence for the design of targeted national policy and interventions to prevent dietary-related ill health in these groups. The findings support further research exploring inequalities in diet quality in the population.

使用新的英国饮食质量调查问卷--UKDQQ,在英国大型队列中按社会人口特征、吸烟和体重状况划分的饮食质量不平等现象。
本研究旨在探讨居住在英国约克郡和汉伯郡的大型横断面成人队列中的饮食质量、社会人口测量、吸烟和体重状况之间的关联。本研究收集了约克郡健康调查第二波(2013-2015 年)中 43 023 名 16 岁以上参与者的数据,内容涉及饮食质量、社会人口统计指标、吸烟和体重状况。饮食质量采用简短的验证工具进行评估。采用多元回归方法评估了这些变量之间的关联。为了建立模型的可移植性,采用了拆分样本交叉验证的方法。样本中观察到的模式表明,女性与男性(3.94 分;P < 0.001)以及非吸烟者与吸烟者(4.24 分;P < 0.001)之间的饮食质量差异最大,女性和非吸烟者的饮食质量得分更高。贫困程度、就业状况、年龄和体重状况类别也与饮食质量有关。在贫困程度较低、从事久坐职业、年龄较大和体重健康的人群中,饮食质量得分较高。交叉验证程序表明,该模型具有良好的可移植性。队列中饮食质量模式的不平等与其他观察性研究结果显示的不平等一致。研究结果表明,由于饮食质量差,人群中与饮食相关的健康不良风险较高,这为制定有针对性的国家政策和干预措施以预防这些人群与饮食相关的健康不良提供了证据。研究结果支持进一步开展研究,探讨人口中饮食质量的不平等现象。
