Intake of sugar sweetened soft drinks among adolescents: Trends and social inequality in Denmark 2002-2018

摘要

Background: Intake of sugar sweetened soft drinks (SSSD) has decreased among adolescents, but trends in social inequality in SSSD intake are unknown. Aim: Examine trends in social inequality in SSSD intake among adolescents in Denmark during 2002–2018. Methods: Five Health Behaviour in School-aged Children surveys with data on SSSD intake and parents’ occupational social class (OSC) from nationally representative samples of 11, 13 and 15 year olds, n =20,112. Results: The overall prevalence of daily SSSD intake decreased from 10.1% in 2002 to 6.4% in 2018. The prevalence decreased in both high OSC (from 8% to 5%) and middle OSC (from 10% to 6%) but remained around 12% in low OSC. The odds ratio (OR) estimates of low compared with high OSC increased over the years around an overall OR of 2.01 (1.74–2.34). Conclusions: Danish adolescents’ SSSD intake decreased during 2002–2018 and was higher the lower the parents’ OSC. Thus, social inequality increased during 2002–2018.
