To examine associations between hours worked and diet quality, frequency of eating out and consuming takeaways.
Data were taken from the National Diet and Nutrition Survey (2008-2014). Associations between hours worked in paid employment and diet quality, assessed using the Diet Quality Index (DQI) and selected foods and nutrients, were tested using linear regression models. Associations between hours worked and frequency of eating out and consuming takeaways were tested using ordinal logistic regression models. All models were adjusted for sex, age, equivalised household income, household composition and household food role.
UK.
Adults (n 2154) aged 19-64 years in employment.
Mean (95 % CI) hours worked per week was 36·1 (35·6, 36·6) and mean DQI score was 41·9 (41·2, 42·5) %. Hours worked was not associated with DQI score, frequency of eating out or consuming takeaways. Hours worked was positively associated with consuming red meat, processed meat and alcohol intake. Adults working more hours had lower intake of fibre but higher total fat and saturated fat intakes if they lived in households with children.
Working hours may not be the main factor driving poor-quality diets among this sample of UK adults in employment. Focusing on consumption of foods prepared outside the household may not be the most efficient way to improve diet quality as effort is needed at all levels. Although it is unclear what is driving the differences in nutrient intakes according to household composition, they are important to consider when developing interventions to improve healthy eating.
研究工作时长与饮食质量、外出就餐频率及食用外卖之间的关联。
数据取自国家饮食与营养调查(2008 - 2014年)。使用线性回归模型检验有偿工作时长与饮食质量(采用饮食质量指数(DQI)评估)以及选定食物和营养素之间的关联。使用有序逻辑回归模型检验工作时长与外出就餐频率及食用外卖之间的关联。所有模型均对性别、年龄、家庭收入等值、家庭构成及家庭食物角色进行了调整。
英国。
19 - 64岁在职成年人(n = 2154)。
每周平均工作时长为36.1(95%置信区间:35.6,36.6)小时,平均DQI得分为41.9(41.2,42.5)%。工作时长与DQI得分、外出就餐频率或食用外卖均无关联。工作时长与食用红肉、加工肉类及酒精摄入量呈正相关。如果在职成年人生活在有孩子的家庭中,工作时长较长者膳食纤维摄入量较低,但总脂肪和饱和脂肪摄入量较高。
在该样本的英国在职成年人中,工作时长可能并非导致饮食质量差的主要因素。仅关注家庭外制备食物的消费可能并非改善饮食质量的最有效方式,因为各个层面都需要做出努力。尽管尚不清楚家庭构成导致营养素摄入量差异的原因,但在制定促进健康饮食的干预措施时,这些因素很重要,需要加以考虑。
