Anthropometric variables as cardiovascular risk pbkp_redictors in a cohort of adult subjects with Turner syndrome

Abstract:

Background and purpose: Excessive adiposity is associated with cardiometabolic complications in Turner syndrome (TS) subjects. Reference data for pbkp_redictive anthropometric indices of overweight/obesity and metabolic syndrome (MetS) are lacking for subjects with TS. The purpose of this study was to identify the best anthropometric pbkp_redictor of cardiometabolic risk in a Latin-American cohort of TS subjects. Patients and methods: This was a cross-sectional correlational study conducted in adult TS subjects (n=88) over the past seven years. Anthropometric parameters, body composition and biochemical variables were evaluated in a study and in a reference (n=57) group. Overweight/obesity and MetS were diagnosed using international consensus. The area under the ROC curve (AUC-ROC) was then used to determine the value of each anthropometric variable in pbkp_redicting MetS or overweight/obesity. Results: The prevalence of MetS and overweight/obesity in TS subjects was 40% and 48%, respectively. All anthropometric and cardiometabolic variables were significantly increased in TS subjects when compared to the reference group, except for body mass index (BMI) and HDL-c. To detect MetS and overweight/obesity, waist to height ratio (WHtR) was found to have a higher correlation with cardiometabolic variables (TC, LDL-c, HDL-c levels and the LDL-c/HDL-c ratio), and to have a higher AUC-ROC and odds ratio than BMI, waist circumference (WC) and the waist to hip ratio (WHR). Conclusion: The prevalence of MetS and overweight/obesity is elevated in TS subjects. WHtR was the most useful variable in pbkp_redicting the presence of MetS and overweight and obesity in this TS cohort. A combination of WHtR with BMI or with WC could have the best clinical utility in identifying adult TS subjects with overweight/obesity and MetS, respectively.
