Consumption of sugar-sweetened beverages (SSBs) has been linked to obesity and type 2 diabetes.
We examined national trends in SSB consumption among US adults by sociodemographic characteristics, body weight status, and weight-loss intention.
We analyzed 24-h dietary recall data to estimate beverage consumption among adults (aged > or = 20 y) obtained from the third National Health and Nutrition Examination Survey (NHANES III, 1988-1994; n = 15,979) and NHANES 1999-2004 (n = 13,431).
From 1988-1994 to 1999-2004 on the survey day, the percentage of adult SSB drinkers increased from 58% to 63% (P < 0.001), per capita consumption of SSB increased by 46 kcal/d (P = 0.001), and daily SSB consumption among drinkers increased by 6 oz (P < 0.001). In both survey periods, per capita SSB consumption was highest among young adults (231-289 kcal/d) and lowest among the elderly (68-83 kcal/d). Young blacks had the highest percentage of SSB drinkers and the highest per capita consumption compared with white and Mexican American adults (P < 0.05). Overweight-obese adults with weight-loss intention (compared with those without) were significantly less likely to drink SSB, but they still consumed a considerable amount in 1999-2004 (278 kcal/d). Among young adults, 20% of SSB calories were consumed at work.
Over the past decade, US adult SSB consumption has increased. SSB comprises a considerable source of total daily intake and is the largest source of beverage calories. SSB consumption is highest among subgroups also at greatest risk of obesity and type 2 diabetes.
