Objective To study the trend and difference of the salivary testosterone and estradiol concentration in girls with different body composition and salivary testostero ne and estradiol concentration.
Methods 75 girls aged 10 were divided into three groups including obese group, moderate group and thin group.To observe for three years and to determine their body composition and salivary testoster one and estradiol concentration.
Results The body fat and lean body mass in three groups increased by the age and the salivary testosterone and estradiol concentration also increased by the age.T estostero ne and estradiol concentration of obese girls aged 12 was significantly higher than that of aged 11.Estradiol concentration of three groups aged 11 was mar kedly higher than that of aged 10.T estosterone concentration of obese group aged 10 was significantly lower than that of thin group.Estradiol concentration had no difference among three groups.T estoster one concentration of moderate and thin girls with menstruation was dramatically higher than those without menst ruation.T estosterone concentration of obese girl with menstruation was significantly lower than that of thin girls.
Conclusion Girls with different body composition or different sexual developmental stage had different testosterone concentration.
