Trends in Sugar-Sweetened Beverages-attributable Burden in Ireland and the UK
Objectives: Excess consumption of sugar-sweetened beverages (SSB) is associated with non-communicable diseases and poor oral health, including dental caries. The objective of this study was to comprehensively assess the burden of SSB consumption by identifying specific long-term trends across five comparable nations – Ireland, Northern Ireland, Scotland, Wales, and England – from 1990-2019 to help inform oral health guidelines. Methods: Global Burden of Disease (GBD) 2019 Study was used to estimate age-standardized summary exposure value (SEV), years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs, DALY = YLL+YLD) across Ireland and the UK from 1990-2019. The GBD data are in public domain systematically collected from many sources. Joinpoint trend analysis was employed to identify and quantify SSB-associated patterns in these metrics by estimating the annual-percent-change (APC). Results: SSB consumption or SEV (per 100) increased yearly across all five regions, but the pace of increase in Northern Ireland and Scotland have slowed in recent years. Ireland had the highest yearly increase in SEV in 2014-2019 (APC=2.3%). Conversely, SSB-related age-standardized YLLs (per 100,000) decreased across all regions until mid-2010s, but increased thereafter, except for England. The largest yearly increase in YLLs was in Northern Ireland (2016-2019: APC=3.5%). SSB-related age-standardized YLDs (per 100,000) increased yearly across all regions from 1990-2019, accelerating since mid-2010s, except for Scotland, which showed a yearly decline from 2014-2017 (APC=-2.7%). Ireland had the largest yearly increase in YLDs from 2015-2019 (APC=9.1%). Overall, SSB-related age-standardized DALYs (per 100,000) declined yearly across all five regions but have increased in recent years. Conclusions: This study showed differential trends in SSB-attributable burden across Ireland and the UK indicating an overall decline in DALYs but an increase in morbidity since mid-2010s, except for Scotland. Such patterns are useful for informing current and future effective population-level strategies and guidelines on oral health and well-being.
