Effects of Nutrition on Osteoarthritis in Women Over the 50 Years: Using the Korea National Health and Nutrition Examination Survey (KNHANES) Data

There are prior articles on osteoarthritis of demographic and nutritional factors, previous studies show a lack of empirical analysis using public data, focusing primarily on predicting or assessing risk factors focusing on demographic characteristics. Since the disease called osteoarthritis itself has yet to be clearly treated, we would like to establish that the preventive medical aspect of osteoarthritis is very important and that prevention through nutrient intake can reduce the social and economic costs of osteoarthritis. We intend to prepare basic data for osteoarthritis by analyzing the prevalence of osteoarthritis in women over the 50 age based on demographic and nutritional characteristics using the 7th National Nutrition Survey data in 2016 and 2017. As results, cholesterol and sodium negatively affect the odds of osteoarthritis and nutrients classified as inorganic reduce the odds of osteoarthritis in 50 age women to 59 years old. In addition, in women over 60 and under 69 years of age, vitamin B has been found to reduce the risk of osteoarthritis and iron has a significant effect on women in their 70s and older. Therefore, these nutrients are ‘micronutrients’ and, among the five major nutrients, were identified as the nutrients that assisted the ‘macronutrients’.
