Oda and Kawai (1) have reported that lower vital capacity (VC) (VC ≤96%) is associated with diabetes but not with the metabolic syndrome (MetS) in nonobese Japanese men and that no significant association between low VC, diabetes, and MetS was found in nonobese women. However, the coexistence of type 2 diabetes and MetS is often observed even in nonobese people (2,3). Furthermore, because both are mostly due to insulin resistance, we wondered whether their involvement in a specific pathology can also occur in normal-weight people.
Therefore, we reanalyzed the data from our ongoing cross-sectional study (4) to evaluate the associations between impaired …
