We thank Safiri S and Ayubi E [1]. for their methodological observations to our manuscript [2]. We agree with their affirmation that the categorization of variables implies loss of information, but we prefer to do so to be able to compare our results with other studies. Indeed, the majority of studies included in a recent systematic reviews [3–6] use BMI categories based on recommendations from the World Health Organization [7], the National Heart, Lung, and Blood Institute [8], and local criteria due to the statistical distribution of the data.
