Objective: To determine the prospective relationship between changes in sugarsweetened beverage (SSB) intake and central adiposity in older children. Design: Dietary intakes of children were obtained by 3 d food records at ages 10 and 13 years. Waist circumference (WC) and weight and height to determine BMI were measured at 10 and 13 years and total body fat mass (TBFM) at 13 years by dual-energy X-ray absorptiometry. Analyses were conducted using multivariable linear regression. Reporting errors were measured and participants were categorized as under-, plausible and over-reporters of dietary intakes. Setting: Community-based British cohort of children participating in the Avon Longitudinal Study of Parents and Children. Results: Among 2455 older children, increased SSB consumption from ages 10 to 13 years was associated with higher WC (standardized β = 0·020, P = 0·19), BMI (β = 0·028, P = 0·03) and TBFM (β = 0·017, P = 0·20) at 13 years. Effects were strengthened among plausible dietary reporters (n 1059): WC (β = 0·097, P < 0·001), BMI (β = 0·074, P < 0·001) and TBFM (β = 0·065, P = 0·003). The association between change in SSB and WC was weakened, but remained statistically significant after accounting for BMI (β = 0·042, P = 0·02) and TBFM (β = 0·048, P = 0·01). Conclusions: Higher consumption of SSB from ages 10 to 13 years was associated with a larger WC at age 13 years independent of differences in total adiposity. Accounting for dietary reporting errors strengthened associations. Our findings further support recommendations to limit intakes of SSB to reduce excess weight gain in children and suggest that SSB have an additional deleterious effect on central adiposity.

Sugar-sweetened beverages Waist circumference Children ObesityObesity is a primary threat to public health. Childhood obesity strongly tracks with age (1) , raising the risk of mortality, CVD, certain cancers and osteoarthritis, as well as other conditions in adulthood (2)(3)(4)(5) . In adults a key driver of the metabolic consequences of excess fat is that located abdominally, or central adiposity, which predicts mortality and CVD independent of BMI (5)(6)(7) . Currently 32 % and 17 % of children and adolescents in the USA are overweight and obese, respectively (8) . Moreover, waist circumference (WC) of children has increased over time and some evidence suggests that the rate of increase in WC has outpaced that of BMI (9)(10)(11)(12)(13) . Therefore, it is paramount to identify modifiable risk factors of excess total and abdominal weight gain in children to help prevent or reverse obesity and its related co-morbidities both in childhood and later life.To date it remains unclear as to whether intake of sugar-sweetened beverages (SSB) has specific effects
