Are polymorphisms in the interleukin-6 receptor gene associated with bone mineral density and body mass index in Spanish postmenopausal women?
These data suggest that variants in the IL6R gene are not only involved in the determination of BMI but also relevant for the determination of BMD. The IL6R gene may belong to the growing list of genes known to be involved in both phenotypes.
Regardless of prepregnancy BMI, LTPA did not affect a woman's GWG according to IOM recommendations. Results may be due to LTPA not differing among BMI categories.
