Risk Factors of Moran et al for Stress Fracture in a Young Female Military Recruit During Basic Training

 

The precise stress fractures were not specified but most presumably would be in the lower extremities.

 

Parameters:

(1) body mass index in kg per square meter

(2) height in cm

(3) subjective sense of burnout on scale from 1 to 7 (in the implementation a VAS scale from 0 to 10 will be scaled appropriately)

(4) serum iron in µg/dL

(5) serum ferritin in ng/mL (or µg/L)

 

X =

= (0.079 * (height in cm)) - (0.105 * (body mass index)) + (0.464 * (burnout score)) - (0.014 * (serum iron)) + (0.035 * (serum ferritin)) - 13.98

 

probability of stress fracture =

= 1 / (1 + EXP((-1) * X))

 

The recruit at greatest risk is one who is tall, lean, iron deficient and burned out.
