Särnblad, S., Magnuson, A., Ekelund, U., & Åman, J. (2016). Body fat measurement in adolescent girls with type 1 diabetes: a comparison of skinfold equations against dual energy X-ray absorptiometry.. Acta Paediatrica, 105 1211-1215. https://doi.org/10.1111/apa.13366
Aim: Skinfold measurement is an inexpensive and widely used technique for assessing the percentage of body fat (%BF) . This study assessed the accuracy of prediction equations for %BF based on skinfold measurements compared to dual -energy X -ray absorptiometry (DXA) in girls with type 1 diabetes and healthy age -matched controls . Methods: We included 49 healthy girls and 44 girls with diabetes aged 12 to 19 years old, comparing the predicted %BF based on skinfold measurements and the %BF values obtained by a Lunar DPX -L scanner. The agreement between the methods was assessed by using an Bland-Altman plot. Results: The skinfold measurements were significantly higher in girls with diabetes (p=0.003) despite a non -significant difference in total %BF (p=0.1). A significant association between bias and %BF was found for all tested equations in the Bland-Altman plots . Regression analysis showed that the association between skinfold measurements and %BF measured by DXA differed significantly (p=0.039) between the girls with diabetes and the healthy controls. Conclusion: The accuracy of skinfold thickness equations for assessment of %BF in adolescent girls with diabetes is poor in comparison with DXA measurements as criteron. Our findings highlight the need for the development of new prediction equations for girls with type 1 diabetes.
