In Reply to ‘Is Sugar-Sweetened Beverage Consumption a Possible Confounder in the Inverse Association Between Coffee and Kidney Disease?’

We thank Dr Natella et al1 for their letter regarding sugar-sweetened beverages being a potential confounder in our study.2 We agree that in observational epidemiology, all possible confounders should be considered and taken into account, if appropriate. Using baseline data from the Atherosclerosis Risk in Communities (ARIC) Study, we ran an analysis similar to Natella et al and also found that sugar-sweetened beverage consumption was significantly lower among those with higher coffee consumption (Table 1).
