Abstract

This study suggested that socio-economical level, waist circumference, body mass index and total body fat percentage are factors that influence decreased bone mineral intensity of Korean adults and control strategies to prevent and decrease the morbidity rate of osteoporosis should be developed based on the results of the study. For the purpose, the study used the results from 2009 Korea National Health&Nutrition Evaluation organized by the Korea Centers for Disease Control and Prevention and implemented from January to December 2009 targeting 7,153 adults consisting of 3,108 men and 4,045 women. As a result of the study, it was discovered that the prevalence rate of bone mineral intensity was 40.3% for the whole population, 32.7% of men, and 46.3% of women. The odds ratios of men in 50s and 60s were 1.85 and 1.66, the odds ratio of the subjects who made 1,000,000-1.990.000 of monthly income was 0.70, which indicates that bone mineral intensity decreased significantly. The odds ratio of total body fat rate was 1.08, which indicates that the higher total body fat percentage, the lower bone mineral intensity. The odds ratios of women subjects in fifties and sixties were 4.15 and 11.96, and the older they were, the less bone mineral intensity was. With educational background of primary school graduates as a standard, the odds ratios of high school graduates was 0.63 and the odds ratio of college graduates was 0.61, and the higher educational background they had, the higher bone mineral intensity they had. With the subjects having job as a standard, the odds ratio of no job was 1.22 and when they had no job, their bone mineral intensity decreased. The odds ratios of total body fat percentage was 1.03 and the higher total body fat percentage, the lower bone mineral intensity. In conclusion, some reasons of low bone mineral intensity of Korean adults were different between factors of men and women, which indicates that more different intervention is necessary. Future studies should consider cause and effects between variables used in the study to identify definitive relations between them.
