Hypothesis

Low levels of physical fitness and health-damaging behaviour at the beginning of military service are associated with an increased incidence of premature discharge from military training.

Conclusion

Low levels of aerobic and muscular fitness and poor school success are associated with premature discharge from military service.

Supporting Evidence

  • 9.4% of participants were discharged for medical reasons, mainly due to musculoskeletal and mental disorders.
  • Low physical fitness was associated with a hazard ratio of 3.3 for medical discharge.
  • Poor school success had a hazard ratio of 4.6 for discharge.
  • Self-assessed health was linked to a hazard ratio of 2.8 for discharge.

Takeaway

If young men are not fit enough when they start military service, they are more likely to get sent home early. This means it's important to be healthy and active before joining.

Methodology

The study followed four cohorts of male conscripts for 6 months, analyzing predictive associations between medical discharge and various risk factors using multivariate Cox's proportional hazard models.

Potential Biases

Potential bias due to the exclusion of conscripts who were discharged before the study began.

Limitations

The study's findings may not be generalizable to women, as only 2.4% of participants were female, and some data were missing due to health issues during measurements.

Participant Demographics

Participants were male conscripts aged 18-28 years, with a median age of 19.
