Determination of the waist circumference threshold for type 2 diabetes risk in Peruvian adults

Determinación del punto referencial de perímetro abdominal para riesgo de diabetes mellitus tipo 2 en adultos peruanos

Abstract

Objective: determine the abdominal perimeter reference point for risk of diabetes mellitus-2 in the Peruvian population.

Methods: analytical and cross-sectional study of the Demographic and Health Survey (ENDES-2022). The entire population was studied (n=28,407). The variables were sex, abdominal circumference (BP) and risk of diabetes mellitus-2 (DM-2) from Bang et al. Diagnostic tests and receiver operating curve (COR) were used. The results were reproduced in the ENDES-2023 population (n=30,782).

Results: in women, the AUC was 0.688 (CI:0.678-0.699; p<0.001), with BP cut-off point for DM-2 risk of 91 cm. In men it was 0.821 (CI: 0.814-0.828; p<0.001), with a cut-off point for DM-2 risk of 88 cm. In men, the international cut-off point (95 cm) and the COR curve (88 cm) had Cramer's V V=0.519;V=0.489), Kappa K=0.507;K=0.496, sensitivity S=64%; S=82%; specificity E=87%; E=61%, respectively. In women, with international parameters (82 cm) and the cut-off point (91 cm), Cramer's V was V=0.115; V=0.240, Kappa=0.060; K=0.203, sensitivity S=88%; S=71%, specificity E=23%;E=57%, respectively. The results were reproduced in ENDES-2023, obtaining similar values.

Conclusions: the abdominal perimeter reference point in the Peruvian population for risk of DM-2 in men was 88 cm and in women 82 cm. The advantages of the PA, which only requires a tape measure, make it a useful tool for DM-2 risk screening for massive epidemiological studies, with the possibility of individualized clinical use in men, being less recommended in women.
