For 1317 adolescents aged 15-19 years logistic regression was used to examine the association of overweight or high waist circumference with fast-food and sweetened beverage consumption, adjusting for potential confounders. Overweight occurs frequently among Jamaican 15-19-year-olds and is associated with increased consumption of sweetened beverages. High WC is more prevalent among females and is related to low consumption of fruits and vegetables. Measures to reduce the consumption of sweetened beverages and increase fruit intake may reduce the prevalence of excess body fat among adolescents.
