Factors affecting osteoporosis in Korean women over 50 years of age

Osteoporosis is a systemic disease in which bone strength is weakened and fractures easily occur due to structural aging. It occurs frequently in the elderly and postmenopausal women, and is particularly closely related to fractures in those over 50 years of age. In addition, the Korea National Health and Nutrition Examination Survey showed that the prevalence of osteoporosis in those over 50 years of age was 34.9% for women and 7.8% for men, confirming that the prevalence of osteoporosis in women is higher than in men. Therefore, the purpose of this study was to identify factors affecting osteoporosis in Korean women over 50 years of age using the raw data from the 8th National Health and Nutrition Examination Survey (2019-2021) of the Korea Centers for Disease Control and Prevention. To this end, we analyzed the data of 1,553 women over 50 years of age among the 22,559 subjects surveyed in the 8th (2019-2021) using the raw data from the Korea National Health and Nutrition Examination Survey. In the data analysis, the general characteristics and lifestyle characteristics of the research subjects were verified by frequency, weighted percentage, mean, and standard deviation through complex sample analysis. The differences in general characteristics and lifestyle characteristics between the normal group and the osteoporosis group were verified by chi-square test. The factors affecting osteoporosis were analyzed by logistic regression analysis. As a result, age, household income, education level, and BMI were identified as factors affecting osteoporosis. Therefore, the results of this study are expected to be helpful in developing osteoporosis prevention and intervention programs in the future.
