Abstract Objective To investigate the relationship between bone mineral density (BMD) and dietary behavior of recruits,and to provide data for reducing the incidence of military training injuries and carrying out well-grounded training programs.Methods A total of 1489 recruits in 2019 had their bone mineral density (BMD) measured and filled in questionnaires on their dietary attitude and dietary behavior.The normal and low BMDs were screened and influencing factors analyzed.Results In terms of attitude to dietary nutrition,the 476 patients in the normal BMD group cared more about their dietary health and balance of daily food intakes than those in the low BMD group (304 cases),and the difference was statistically significant (P<0.05).Multivariable logistic regression analysis showed that dietary balance (OR=0.534,95% CI 0.370-0.770),daily intake of eggs(OR=0.603,95% CI 0.412-0.882) and milk consumption met(OR=0.419,95% CI 0.286-0.615) the dosage recommended by Chinese residents' dietary guidelines.Daily exercise (OR=0.653,95% CI 0.449-0.949) and outdoor activity time>2 hours(OR=0.153,95% CI 0.057-0.411) were protective factors,while habitual drinking of carbonated beverages (OR=3.182,95% CI 2.117-4.284) was a risk factor for BMD.Conclusions 38.8% of the recruits surveyed this time had a low BMD.There is the need to make individualized training plans,popularize relevant knowledge,and develop proper diet behavior in order to improve bone mineral density.
