Considering that adolescent females with T1D, as also found in this study, are often heavier than their non-diabetic peers as a side effect of intensified insulin therapy and other life-style factors (Domargård et al., 1999; Fröhlich-Reiterer et al., 2014; Minges et al., 2017), it could be hypothesized that their parents may further stress the importance of thinness and consequently pressure daughters to take control of their weight to better meet diabetes rules. This evidence concerns the gene INS and diabetes mellitus.
