Relationships between age, body weight, physical fitness and sex-hormone-binding globulin capacity.

Semmens JB, Rouse IL, Beilin LJ, Masarei JR.

The associations between sex-hormone-binding globulin capacity (SHBG), age, body mass index (BMI), and physical fitness have been studied in 34 men and 36 women. Multivariate analysis was used to look for independent associations with SHBG. The data indicate that when controlled for a number of other factors SHBG levels are related, in men but not in women, to age (positively, p less than 0.001) and BMI (negatively, p less than 0.001).
