Abstract :
Background Military recruits undertake intense loads of physical
training as part of their recruitment to reach a physical level
compatible with their line of duties. This training is often conducted
over a short time span and complicated by injuries and premature recruit
discharge. Identification of risk factors that could decrease the risk
of injuries is ideal. Objectives The present study aimed at correlating
pre-recruitment vitamin D levels to injury risk during basic military
training in a group of recruits. Methods A total of 90 recruits
commencing their basic military training were invited to participate in
the study. The cohort comprised 81 males and 9 females, with a mean age
of 22.6. All acute and gradual onset musculoskeletal injuries as well as
medical ailments were recorded using the Orchard Sports Injury
Classification System. Injuries and medical ailments were analyzed for
associations with vitamin D levels. Recruits were grouped according to
their serum vitamin D levels into deficient, insufficient, or sufficient
as per the Endocrine Society range guidelines. Results A total of 34
(26.2%) recruits sustained at least 1 injury during the course of their
basic military training. Vitamin D level as well as vitamin D status was
not associated with injury risk although weak rejection of association
with leg injuries and vitamin D insufficiency status was noted (P =
0.057). A total of 60% of recruits were identified as being vitamin D
deficient or as having insufficient vitamin D levels. Conclusions
Vitamin D deficiency and insufficiency are relatively common in areas
with high mean sunlight exposure and should be considered in individuals
who might otherwise be at risk. Further studies are recommended in the
military using larger populations and possibly focusing on leg injuries.
