ABSTRACT
OBJECTIVE:
To determine the cardiometabolic risk of adolescents and adults with Turner syndrome (TS) and whether and how anthropometry and body composition predict this risk.METHODS:
We compared the anthropometric, biochemical, and dual-energy x-ray absorptiometry-derived body composition parameters of 103 girls and women with TS aged 12 to 30 years and 103 controls of the same age and body mass index (1) between TS with and without metabolic syndrome (MetS), (2) between the different karyotypes of TS, and (3) between growth hormone recipients and nonrecipients.RESULTS:
Individuals with TS had higher prevalence rates of truncal obesity (57.2%), MetS (37.9%), prediabetes (20.4%), dyslipidemia (73.8%), hypertension (9.7%), and hepatic steatosis (15.5%) and a greater total body fat percentage (38.43% vs 34.26%) and fat mass index (9.15 vs 6.71 kg/m2) but a lower lean mass index (11.05 vs 12.49 kg/m2) than controls (P <.001). Individuals with TS and MetS (n = 39) had a higher total body fat percentage (41.74% vs 36.42%, P <.0001), truncal fat percentage (44.66% vs 36.09%, P <.0001), and visceral adipose tissue mass (495.57 vs 276 g, P <.0001) than those with TS but without MetS. Those with classic TS (45,X) had a higher prevalence of prediabetes (32.6% vs 10.5%, P =.01). Growth hormone recipients had a lower prevalence of MetS and lesser truncal obesity. Altered body composition was significantly correlated with metabolic risk. The truncal fat percentage independently predicted MetS (odds ratio, 1.12; 95% confidence interval, 1.003-1.24; P =.04). Waist circumference and waist-hip ratio predicted metabolic risk with good sensitivity and specificity.CONCLUSION:
Adverse cardiometabolic risk and altered body composition start early in life in TS. Postpubertal women with TS should be routinely assessed for truncal obesity, dysglycemia, dyslipidemia, and liver steatosis, irrespective of body mass index and karyotype.Palavras-chave
