Cross-sectional associations between lunch-type consumed on a school day and British adolescents' overall diet quality.

Diet quality of children consuming school meals tends to be better than that of children consuming packed lunches (from home) or food bought outside school. This study investigates the association between different types of lunch consumed in a school day and diet quality of UK adolescents. A total of 2118 British adolescents were included from the National Diet and Nutrition Survey (Years 1-8; between 2008 and 2016).

The cross-sectional relationships between consumption of takeaway food, eating meals outside the home and diet quality in British adolescents.

Objective: The present study aimed to evaluate the association of frequency of consuming takeaway meals and meals out with diet quality of UK adolescents.

Design: The Diet Quality Index for Adolescents (DQI-A) tool was used to assess diet quality, where adolescents' food intake was based on 4d diary records obtained from the UK cross-sectional National Diet and Nutrition Survey (NDNS) rolling programme Years 1-6. Models included confounders.
