摘要
Aims: To investigate risk factors for metabolic syndrome in prepubertal boys with Klinefelter syndrome. Methods: Eighty-nine boys with Klinefelter syndrome, ages 4-12.9 years, and 34 age-matched control boys had height, weight, waist circumference and blood pressure measured and their parents completed a questionnaire about physical activity. The boys with Klinefelter syndrome also had measurement of lipids, fasting glucose and insulin. Insulin-glucose homeostasis model assessment was calculated, and the boys were evaluated for childhood metabolic syndrome. Results: The Klinefelter syndrome and control groups were similar ages (7.5 +/- 2.4 vs. 8.1 +/- 2.3 years). Body mass index measurements were similar, but waist circumference was > 90 percentile in 30% of boys with Klinefelter syndrome versus 21% of controls. The mean daily time spent running was 42 min less in the Klinefelter syndrome versus control groups (p < 0.01). About 37% of the boys with Klinefelter syndrome had elevated LDL cholesterol, 24% had insulin resistance, and 7% met the three criteria for diagnosis of metabolic syndrome. Conclusions: Truncal obesity, insulin resistance and metabolic syndrome are present in boys as young as 4-12 years with Klinefelter syndrome, and these occur in association with reduced running-type activity.
