Association between dietary factors and health-related quality of life in adolescents longitudinally over three years from age 11-16 years.

ABSTRACT:

Background

Cross-sectional studies have linked adolescent food choices to health-related quality of life (HRQoL). This research sought to determine the degree to which adolescent food choices are linked to HRQoL longitudinally.

Methods

Data were collected in the UK as part of the Wellbeing in Schools (WiSe) survey. Adolescents (N = 2241) (49% female, n = 1112) were surveyed at age 11-12 (2014); 13-14 (2016); and 15-16 years (2018). HRQoL was assessed using the Kidscreen10 and food intake using a 17-item short food frequency questionnaire (sFFQ). Confirmatory factor analysis of FFQ responses indicated five food factors (junk food; fruit and vegetables; bread and dairy; meat; protein). Using a bidirectional strategy the five food factors and HRQoL were examined at three points
