Abstract P6-10-01: Consumption of sugar-containing beverages and cancer risk: Results from the NutriNet-Santé prospective cohort

Abstract

Abstract OBJECTIVE To assess the associations between the consumption of sugar-containing and artificially sweetened beverages and cancer risk. DESIGN Population based prospective cohort study. SETTING AND PARTICIPANTS Overall, 101 257 participants aged ≥18y (mean age: 42.2±14.4y) from the French NutriNet-Santé cohort (2009-2017) were included. Consumptions of sugar-containing and artificially sweetened beverages were assessed using repeated 24h-dietary records, designed to register participants' usual consumption for 3300 different food and beverage items. MAIN OUTCOME MEASURES Associations between beverage consumption and overall, breast, prostate and colorectal cancer risk were assessed by multivariable Cox Proportional Hazard models adjusted for known risk factors. RESULTS A 100mL increase in the consumption of sugar-containing beverages was significantly associated with an increased risk of overall cancer (HR=1.08, 95% confidence interval 1.04 to 1.12, P<.0001) and breast cancer (HR=1.11, 95% confidence interval 1.04 to 1.19, P<0.002). The consumption of artificially sweetened beverages was not associated with cancer risk. In sub-analyses, a 100 mL increase in the consumption of 100% fruit juice was significantly associated with an increased risk of overall cancers (HR=1.08, 95% confidence interval 1.02 to 1.15, P=0.01). These associations were strongly mediated by the sugar contained in these beverages. In contrast, weight gain during follow-up did not appear as a strong mediator. Besides, results were similar in overweight and non-overweight participants. CONCLUSIONS In this large prospective study, a 100mL increase in the consumption of sugar-containing beverages in the diet was associated with an 8% significant increase in overall cancer risk and an 11% significant increase in breast cancer risk. 100% fruit juices were also associated with an 8% increased risk of overall cancers. Given the massive consumption of sugar-containing beverages in Western countries, these results suggest that they may represent a key modifiable risk factor for cancer prevention.
