Background: Waist-to-height ratio (WHtR) is one of the anthropometric measures associated with cardiovascular risk (CVR). However, WHtR cut-off points may vary depending according to population characteristics, including sex and height.
Objective: To identify optimal WHtR cut-off points to predict CVR factors by sex in Mexican adults according to height.
Material and methods: Information from adults >20 years (n = 3550) from the 2016 National Health and Nutrition Survey were analyzed. Prevalence of high WHtR, CVR factors (glucose and insulin, lipid profile (total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) and blood pressure were estimated by sex and height (short height <1.60 and <1.50 m in men and women, respectively). The maximum proximity procedure was used to establish the point of maximum simultaneous sensitivity and specificity using the operating characteristic curve of the receiver. The estimates were stratified by sex and height condition.
Results: The WHtR cut-off points identified to predict CVR were higher than those suggested for international use (≥0.5), being significantly higher (p <0.0001) for women (0.61) than for men (0.56). Also, the WHtR cut-off points were higher for short stature (men 0.58 and 0.56, women 0.63 and 0.58, with short and normal stature, respectively).
Conclusions: The WHtR cut-off points for predicting CVR in the Mexican population were higher than 0.5 in both sexes and it was higher for individuals with short stature. The identified cut-off points may be an additional tool in screening the adult population in Mexico to predict CVR.
