Despite the accumulated evidence on the health risks associated with sugar-sweetened beverages (SSB), the industry has funded mass communication strategies promoting the idea that soft drinks, including SSB, may represent a source of well-being. This study assessed the association between consumption of soft drinks and health-related quality of life (HRQL), as a proxy of well-being, in the adult population of Spain.


The cohort was established in 2008-2010 with 8417 individuals representative of the Spanish population aged 18-60 years. Habitual soft drink consumption was assessed with a validated diet history at baseline. HRQL was measured using the SF-12 questionnaire at baseline and in a subsample of 2132 study participants in 2012. The analyses were performed using linear regression and adjusted for the main confounders.


In cross-sectional analyses at baseline, those who drank ⩾1 serving/day of SSB had a lower (worse) score on the physical composite summary (PCS) of the SF-12 (adjusted linear regression coefficient: -1.08; 95% confidence interval (CI): -1.60 to -0.54) than those who drank <1 serving/week. Results were similar among individuals younger than 35 years (-1.06; 95% CI: -1.79 to -0.32), those who were not dieting (-1.21; 95% CI: -1.80 to -0.62), those who did not lose >5 kg in the previous 4 years (-0.79; 95% CI: -1.87 to 0.29), and in those without morbidity (-1.18; 95% CI: -1.91 to -0.46). Neither SSBs nor artificially sweetened beverages (ASBs) showed an association with the mental composite summary (MCS) of the SF-12. In the prospective analyses, no association was observed between baseline consumption of SSBs or ASBs and the changes in the PCS and MCS score from 2008/2010 to 2012.


No evidence was found that soft drink consumption has a beneficial effect on either the physical or mental dimensions of HRQL.
