PBF: Percent body fat; PLM: Percent lean mass; HDL: High density lipoprotein cholesterol; TC/HDL: Total cholesterol/HDL ratio;
LegL: Leg lean mass; CoitalF: Coital frequency per month; SOsteop: Osteoporosis of the spine at L2-L4;
HOsteop: Osteoporosis of the hip at the femoral neck; HOsteopn: Osteopenia of the hip at the femoral neck;
HOMA: Homeostasis Model Assessment score.
